C Language Programming is one of the main courses for computer science majors’ students. As the first programming language, it is difficult to learn and teach for both of students and teachers. In our traditional teaching methods, we had to introducing statements and syntaxes, in addition to some simple examples. However, this method showed the lack of logic system training in the programming approach and the students taught by this mode were not so competent for handling problems occurring in programming. Therefore, the teaching method of C Language programming needs reforming. After years of experiencing the new teaching modes, we come to a conclusion that teaching C Language Programming should be based on the programming approach, importing the software engineering ideas into teaching, and practicing Case Studies and Project teaching mode, i.e, teaching students in accordance with their aptitude.

This paper is concerned with an optimization design for the solar car body under a single load is carried out by using finite element optimization design (FEOD) model. Topology optimization and sizing optimization are explored to find out an optimal manufacturing feasible design from multiple optimized designs of material reinforcement of the solar car body for rigidity improvement. The application of these methods demonstrates that through innovative utilization of the topology optimization technique, an optimal manufacturing feasible design can be obtained. The relationship between the rigidity improvement and different configuration of material reinforcement is also investigated. It is concluded that through appropriate application of FEOD methods, the overall rigidity of the solar car body framework can be improved substantially in a cost effective manner and provides more convincing evidence for optimization design of the solar car body. The results demonstrate that the optimized solar car body is safer and lighter.

This paper proposes the construction mode of a two-level distributed alarming system, in which alarms are coordinately processed by substations and control center. In substation side, we classify alarms into several grades according to the degree of their importance and send the extracted key alarms to control center, thus reduce the amount of alarm passing and ensure the transmission reliability and speed; meanwhile, we carry out alarm verification and pretreatment through information redundancy to validate alarm correctness. In control center side, we integrate the data of ordinary Supervisory Control and Data Acquisition (SCADA) and the alarms received directly from substations, and carry out comprehensive fault reasoning and correctness verification. In order to illustrate the feasibility of the substation-control center distributed alarming system, the overall structure, substation smart alarm (SSA), control center smart alarm (CCSA) and cooked data transmission of this construction mode will be discussed in detail.

β-SiC particles were synthesized using silicon powder and carbon black at 1300°C. The effect of grinding the silicon powder raw material into smaller particles on the synthesis and crystallinity of the SiC particles was investigated. The size of the silicon particles decreased and the surface of the silicon particles increasingly oxidized into silicon oxide with increasing grinding time, thus decreasing the yield of SiC because of the higher SiO2 content in the ground silicon powder, since SiO2 transforms into SiC at a higher temperature than does silicon. Although the sizes of the silicon particles in the raw materials were different, all the synthesized SiC crystallites showed similar size. Transmission electron microscopy-energy dispersive X-ray spectroscopy analysis showed that although most of the synthesized SiC particles were smaller than 100 nm, the primary SiC particles had aggregated, and some unreacted silicon was observed inside the large aggregated SiC particles.
