Abstract
Here, we report on role of pre-ionization using non-resonant 2.45 GHz microwave heating (P
2.45 GHz < 20 kW) in plasma start-up of neutral beam injection (NBI) for heliotron configurations in low beam power (P
NB) under non-resonant heating condition. A rapid electron heating towards burn-through of the low-Z impurities was observed experimentally in the early phase of beam injection when the seed plasma density produced by the non-resonant heating was enough for the plasma start-up. Beam heating time to the burn-through increased with decreasing the seed plasma density and a critical density condition of the seed plasma for successful start-up was observed experimentally. Proper timing of the gas fuelling is critical for plasma expansion because the beam fuelling is not significant. A 0-dimensional (0D) model analysis of the NBI start-up developed in this study well reproduces the experimental results. The 0D model clarifies the physical mechanism of the NBI start-up using pre-ionization described as follows: (1) the seed plasma produces sufficient beam ions immediately after beam injection, (2) the beam ions heat up electrons that promote the ionization/dissociation of the background neutrals, (3) this process acts as a positive feedback loop resulting in further electron heating towards burn-through. The 0D model analysis shows that the critical density corresponds to the state at which the electron heating by the beam ions is equal to electron power loss due to conduction and ionization/dissociation.

Authors: Shi Ling , Liu Honghai , Xi Chen , Zhang Zhiwen 
Published: August 2021

Abstract
At present, many cities in China have both severe water shortages and waste of large amounts of rainwater resources during heavy rains caused by urbanization. Turning rainwater resources into cities can reduce urban runoff and reduce peak floods. At the same time, it can increase urban water supply, beautify and clean the urban environment, improve urban microclimate, reduce ground subsidence, control rain and flood processes and reduce urban flood control. Drainage infrastructure investment greatly reduces urban flood disasters, which will bring considerable economic, social and environmental benefits. Therefore, as one of the hot topics in the preparation of special plans for drainage engineering in the new period, urban rainwater should be carried out using the SWMM model and computer software. The plan provides the possibility for further compiling special plans for rainwater utilization and guides the utilization of urban rainwater resources.

Published: August 2021

Abstract
The development of multimedia technology makes English learning more and more simple. This paper mainly studies the influence of four different annotation forms, namely Chinese, English, Chinese + pictures and English + pictures. The results showed that the Chinese annotations were more effective than the English annotations in promoting incidental vocabulary learning. The combination of text and picture annotation is more conducive to incidental vocabulary learning than the text-only annotation. Among the four kinds of annotations, the combination of Chinese and pictures is the most effective for incidental vocabulary learning. Those with higher English proficiency are significantly better than those with lower English proficiency in using annotations to learn vocabulary and maintain word memory.
Research on the Development of Computer Cross Border E-Commerce from the Perspective of International Trade
Authors: Tang Xiaojing 
Published: August 2021

Abstract
Based on the perspective of ITT, the development of cross border e-commerce (hereinafter referred to as CBEC) is directly related to many industries, which promotes the employment and development of many industries, such as logistics, it, production, etc. Therefore, CBEC accounts for a large proportion in economic development. With the improvement of e-commerce platform, the traditional international trade (hereinafter referred to as ITT) has gradually changed to CBEC. In the perspective of ITT, the “Internet plus foreign trade” CBEC is a modern sales way, which caters to the characteristics of the fragmentation of sales orders and the individualization of product demand. Therefore, the average annual growth rate of CBEC in China exceeds 30%, which has become a new direction of ITT transformation and upgrading. Through CBEC, ITT has broken through the limitation of time and space, which has gradually reduced transaction costs. Therefore, computer CBEC has a positive impact on ITT. First of all, this paper analyzes the role of CBEC development. Then, this paper puts forward some problems. Finally, some suggestions are put forward.

Mathematics exists in all aspects of human society, which plays an important role in production and life. With the application of computer technology, mathematical computing ability has been greatly developed, which can also be used to calculate more complex social problems. Therefore, solving practical problems through mathematical methods has become the most important way. Mathematical modeling is a tool to solve practical problems, which is also an important basis for computer application in various industries. Through the idea of modeling, we can solve many practical problems. Therefore, college teachers should make rational use of the idea of modeling in mathematics teaching, which has important theoretical and practical value. By cultivating students’ awareness of discovering, analyzing and solving problems, colleges can cultivate students’ observation ability, abstract ability and cooperative spirit, which will improve students’ ability of applying mathematics.
