Abstract
In order to solve the new threats to human health and the earth environment brought by the large number of discarded power batteries in the future, we propose a method of power battery evaluation and recovery. We use trusted block chain technology to build a scientific, efficient and reliable power battery evaluation and recovery platform, through the power battery production, sales, use and recovery process, contact the manufacturers, dealers, users, charging stations, and other nodes. At the same time, through the battery built-in BMS system and wireless communication terminal, real-time access to the battery usage and performance parameters. When it is detected that the power battery meets the recycling standard, the battery can be transported to the waste battery treatment center through the logistics network established by the manufacturer. The treatment center uses alkaline precipitation and biocatalysis to centrally process the recycled materials and realize the recycling of the recycled materials. The method breaks down the technical barriers in the field of power battery evaluation and recovery, and provides scientific, efficient and advanced support for environmental protection.

Authors: Gao Zan , Jin Penggang , Ren Songtao , Yang Jian 
Published: October 2019

Abstract
A testing system was established to measure at 71°C the expansion pressure of a thermoplastic explosive with different charge quantities and of thermoplastic explosives with the same charge quantity but different formulations. It is indicated that the growth of expansion pressure of the thermoplastic explosive is non-linear with the increase rate of the charge quantity. And the expansion pressure has the possibility of decreasing when the charge quantity reaches a certain value. The expansion pressure will vary remarkably with the selection of polymer materials with differed dynamic mechanical properties as additives.

Published: October 2019

Abstract
The water level of NO.2 high pressure heater rised when the 150MW turbogenerator set of a power plant operated normally, it was unassembled and checked. After the high pressure heater was put into operation, the water level of the boiler drum droped. After the standby electric pump was started and the electric load was reduced, the water level of the boiler drum still droped, resulting in the boiler feed water flow reduced to the protection action and the unit shutdown. Through inspection, it was found that the connecting rod pin of the manual valve at the outlet of the high-pressure heater was broken, which maked the manual valve at the outlet not fully open and lead to low water flow rate at the water side of the high-pressure heater.After the corresponding improvement and optimization measures were taken, the unit can be restarted and run normally .

Published: October 2019

Abstract
During the performance test of the unit, the HP heater emergency hydrophobic leakage will lead to errors in the calculation of the flow flowing through the turbine, thus causing deviation in the calculation of the test results. The influence of the main flow benchmark of feed water flow and condensate flow at the deaerator inlet on the test results is given by an example. The effect of the HP heater emergency hydrophobic leakage on the economy of the unit itself is analyzed by the equivalent heat drop method. It is concluded that when the condensate flow at the deaerator inlet is the main flow benchmark, the result deviation of the test results is much greater than that of the leakage on the economy of the unit itself.

The design of the cross-arm frame, the joint design and the dimensional design are considered. The finite element static analysis is carried out in ANSYS, and results show the maximum deflection of the cross-arm is 36.8mm in the condition of loads long-term effects. According to the national design code for overhead transmission lines, the maximum node displacement of the 35kV FRP cross-arm tower meets requirements of the national code. In addition, the maximum stress of the 35kV composite cross-arm tower is 242MPa, which is far less than the FRP strength values 1130MPa listed in the Mechanics of composite materials, so its design strength also meets the design requirements. Subsequently, through economic analysis, it shows that there are good economic benefits, social benefits and broad application prospects in the 35kV composite cross-arm tower.

Authors: Wang Guochun , Zhang Xuesong , Liu Shengchun , Ma Longtao , Li Bo , Wu Xueliang , You Yi 
Published: October 2019

Abstract
Aeolian vibration control measures for JL/G1A-400/35-48/7 conductors were studied with the energy balance method. The results show that the dynamic bending strain of the JL/G1A-400/35-48/7 conductors with FR dampers is much smaller than the conductor itself under a tension level of 25% RTS, but the dynamic bending strain of the conductors exceeded 120×l0-6 when vibration frequencies are between 30 Hz and 40 Hz and additional FR dampers have no obvious effect. The festoon wire dampers have very good energy dissipation capacity within wide frequencies. The Bate wire dampers were eventually designed as combinations of a 1.2 m single festoon wire dampers, which could reduce the dynamic bending strain of the JL/G1A-400/35-48/7 conductors between 30Hz and 40 Hz. The Bate wire dampers combined with FR dampers could respond to most of the frequencies experienced over the range of wind speeds causing vibration, and keep the dynamic bending strain of the JL/G1A-400/35-48/7 conductors under the required standard, which provides a reference for research and construction of UHV engineering projects.
Finite-time Extended State Observer Based Adaptive Optimal Control of Continuous-time Linear Systems
Authors: Zhang Qinghua , Lin Yong , Wen Yangdong 
Published: October 2019

Abstract
In this paper, a novel strategy iterative method based on finite-time extended state observer is proposed to find the online adaptive optimal controller for a class of linear continuous-time systems with completely unknown system dynamics and unmeasurable state variables. In this method, finite-time state observer estimates the system state variables by using the input and output information of the system and the policy iterative method uses the estimated state variables and system input information to iteratively solve the algebraic Riccati equation until the adaptive optimal controller is obtained. It is worth noting that the method proposed in this paper only uses the input and output information of the system, without requiring the apriori knowledge of the system matrices and the state variables. A numerical simulation example will be provided to demonstrate the effectiveness of the method.

Missile-borne image guidance system is still facing a series of difficult issues of anti-interference. This paper constructs a practical image tracking model using Kalman Filter based on fusion of MEMS-IMU Data and Vision Data after deriving the transformation matrix between the image sequences and MEMS-IMU data. The tracking model is tested by experiments. The result shows tracking based on fusion of MEMS-IMU Data and Vision Data is an effective solution of rotating scene and tracking accuracy is about 4 times better than vision only.
