Authors: Guo Feiran , Liu Qin 
Published: July 2020

Abstract
In the early stages of China’s economic development, the development mode characterized by “high pollution, high cost, and low efficiency” caused serious environmental pollution and resource shortages. The mode gradually restricted the healthy development of the industry. Accelerating economic system reform and promoting an update of green transformation about the industry are imminent. This research is based on text mining and sorting out of existing literature and news comments to construct an evaluation index for the green innovation capability of manufacturing companies. Through empirical research of new energy vehicle companies, this paper further analyzes the green innovation levels of typical domestic new energy vehicle companies. Empirical evidence shows that the level of green innovation of an enterprise is mainly determined by its ability to innovate green technology, and at the same time it is affected by the multiple effects of government policies, market environment, and consumer behavior. Finally, this article puts forward relevant suggestions for the development of the new energy vehicle industry from the government and enterprise levels.

Published: July 2020

Abstract
Irrigation water consumption statistical work is very important to water resources management. As for Zhejiang province, the problems of irrigation water consumption statistics are that there are too many water sources to monitor which discharge and too many usages to separate from a certain amount of water. At the meantime, the irrigation water can return to the downstream fields and be reused in its irrigation, but the amount of reuse water is very difficult to monitor and count. Taking Wanyao irrigation area as the study object, the layout methods of monitoring facilities built to monitor the key sectors of water circulation were proposed, including the supplication sector, the utilization sector and the drainage sector. The water circulation model of irrigation area was constructed based on the monitoring facilities’ observed data, then the constructed model was applied to simulate the natural water circulation and the social water circulation. The supplication and utilization progress of irrigation water were extracted from the simulation results, and the reuse progress of irrigation water was analysed. Actual irrigation water consumption in irrigation area was counted in the last. The result shows that it’s feasible economically and technically to layout the monitoring facilities based on water circulation simulation of irrigation area, and the statistics method of irrigation water consumption by simulating the water circulation is reliable and high precise.

Authors: Ling Mei , Xin Yu , Peng-ming Jiang 
Published: July 2020

Abstract
Plant roots have a positive effect on shallow landslides on slopes. In order to study the influence of typical vegetation on the slope stability in the hilly area of the lower reaches of the Yangtze River, the triaxial test was used to obtain the shear strength parameters of the root-soil complex of typical vegetation of Salix babylonica and Pterocarya stenoptera in the hilly areas of the lower Yangtze River. On this basis, the slope stability calculation model based on the limit element theory is established. The safety factor of the reinforced slope was calculated under three kinds of slope conditions (30°, 39°, 45°), and the influence of root type, position and depth on the slope stability was analyzed. Studies have shown that different types of plant roots mainly affect the stability of slope by enhancing the cohesion of soil. The improvement of slope stability by root system is related to the reinforcement position of root system. The effect of vegetation root on the reinforcement effect of slope The range is roughly in the vicinity of the sliding surface of the slope, and the closer to the sliding surface, the better. Plant roots have a peak effect on the slope at a certain depth, not as deep as possible. This paper provides a reference for studying the influence of vegetation on slope stability, and provides a reference for guiding the slope greening in the hilly areas of the lower Yangtze River.

Authors: Chen Lei 
Published: July 2020

Abstract
During the typhoon period, sudden silting is easy to happen in the port area, which will affect the normal operation of the ship. It is an important reference for port maintenance to evaluate the Sudden Siltation after typhoon. In this study, a coupled mathematical model of wave, tidal current and sediment is established to simulate the sudden deposition of Ruoshan port area under the action of typical typhoon. The results show that the sediment concentration in the typhoon period is much higher than that in the normal weather because of the larger current velocity and the obvious wave action. The research results can provide design support for dredging and maintenance of Ruoshan port.

Published: July 2020

Abstract
In order to optimize the structural parameter setting at the transfer point, the principle of CFD-DEM coupling is used to simulate the production conditions of the material mass flow rate: 150kg/s, height difference: 3m, material density: 1400kg/cm3, and the operation of different structural parameter settings at the transfer point. Based on the pumping volume, equipment wear degree and dust concentration in the exhaust pipe, the weight coefficients of the three indicators given by the comprehensive analytic hierarchy process and the CRITIC method are 0.49, 0.32 and 0.16 respectively, and then the structure parameter settings obtained by the orthogonal test are simulated and optimized by using the BP neural network model. The optimized parameters of orthogonal test are the chute angle of 45 degrees, the number of suction ports of 3, the belt speed of 1.5m/s and bandwidth of 1000mm; the optimized parameters of BP neural network model simulation are chute angle of 45.53 degrees, the number of suction ports of 2.86, the belt speed of 1.48m/s and the bandwidth of 996mm. The results show that the BP-ANN model has the advantages of simplification, high efficiency and time saving, and can provide a new method for enterprises to set the structural parameters at the transfer points reasonably according to their own production conditions.
Discussion on the dynamic corner frequency in the case of 2011 Great East Japan Earthquake
Authors: Tao Zhengru , Wang Xinyan , Song Yana 
Published: July 2020

AbstractFor the simulation of broadband near-fault ground motion, one of the key points is to start with a reasonable source spectral model. Corner frequency is a parameter of source spectrum. We redefined the parameterNRijof the dynamic corner frequency as the number of rupturing sub-faults, rather than that of ruptured ones, in the model of Motazedian and Atkinson (2005). Four sizes of sub-fault are given, and ground motion on 51 bedrock stations is simulated randomly by a finite fault model, in the case of the 2011 Great East Japan Earthquake. The variation with sub-faults size is reduced to a certain extent, and the improvement is more obvious at the periods of 0.1-1s. By comparing with the response spectra of strong ground motion records, the long-period parts fit better, and the short-period (≤0.1s) parts are lower than the observed spectra, while for several stations, the simulated spectra fit with the observed ones over the periods to 10s. And, the influence of the corresponding energy conservation factor (or scaling factor) on the simulated ground motion is analysed. Compared with strong ground motion records, the dependence on sub-fault size is further weakened, and the simulated spectra fit with the observed ones at the periods of less than 0.1s.

Published: July 2020

Abstract
Based on a certain low-head ecological weir project’s requirement of the fishway construction and fish migration, a three-dimensional mathematical model of a natural fishway was established. The structure of the fishway which includes the bottom slope and the number of partition walls has great influence on the water flow conditions of the fishway pond room, which were analyzed from three aspects: the flow pattern of the tank room, the mainstream flow velocity, and the turbulent kinetic energy. The numerical simulation results were verified by model tests. The results of the research show that when the bottom slope is set to i = 1:35 the natural fishway has an obvious three-dimensional water flow structure. What’s more, under this circumstance, the mainstream of the fishway is clear, the flow pattern is good. The overall turbulent kinetic energy is not large, and the maximum flow velocity at the vertical joint is basically the same, slower than 1.5ms−1, which basically meets the target fish’s traceability requirements. With pebbles applied, the flow of the water in the pond room becomes richer. With the traceback path increased, the efficiency of fish communities can be vastly improved. The actual application of the fishway should adjust to the design of the ecological weir and its topographic and geological conditions.

Published: July 2020

Abstract
Removal of NOX and SO2 from flue gas by Ozone (O3) oxidation and NaOH absorption was carried out in practical engineering. The effects of the liquid to gas ratio (L/G), the molar ratio of O3 dosage and initial content of NOX (O3/NOX), pH and NaOH concentrations on the removal efficiencies of NOx and SO2 were investigated. In addition, the influences of O3/NOX and voltage on the removal of PM were analyzed. The results show that the NOX removal efficiency increases with the increasing of O3/NOX (0∼2.0), solution pH (4∼7) and L/G (2∼8), while is slightly affected by NaOH concentration (0.05∼1%). The SO2 removal efficiency increases with the increase of L/G from 2 to 8 L/Nm3, but is hardly changed by O3/NOX (0∼2.0), NaOH concentration (0.05∼1%) and solution pH (4∼10). It was found that the outlet concentration of PM (CPM) decreased with the rise of voltage ranging from 0 to 40 kV, however, slightly increases with the increment of O3/NOX at a range from 1.6 to 2.0. The optimal operating conditions can be established when taking running costs and rigorous ultra-low emission standards into consideration. Under the optimal conditions, the removal efficiencies of NOX and SO2 reached more than 75% and 98% respectively, and CPM could be also controlled within 5 mg/Nm3.

Authors: Haifeng Wang , Leiyu Feng 
Published: July 2020

Abstract
Non-destructive detection with colored-liquid was an effective detection method, which was widely used in non-destructive detection industry. High-concentration of wastewater with COD, color and surfactants would be produced in detection process. Through the biochemical treatment combined with wet oxidation, the COD dose would be reduced from 49200 mg/L to less than 100 mg/L. The color will be degraded from 5000 times to less than 40 times, which will match the requirements for reuse and discharge. Through the molecular distribution and bacteria toxicity test, wet oxidation reduced the inhibition rate of toxicity from 99.99% to 90.88%, which promoted the biochemical treatment performance. The average molecular weight of non-destructive wastewater was reduced obviously from 1486118 to 20376. In the end, the residual chlorine indicator was used to control dose of chlorine less than 3 mg/L to ensure that the color was less than 40 times and residual chlorine was not harmful to environment. The oxidation process was intelligence oxidation. The lab-scale experiment provided potential and available treatment process for non-destructive detection-wastewater.
