The literature reading course is to carry out teaching activities around the main line of scientific and technical literature retrieval, reading and discussion. In the aspect of cultivating students' innovation ability, it has the advantage that can not be replaced by other courses. In this paper, the cultivation of students' innovation ability as the core of teaching thought, and the literature reading teaching mode are discussed in the systematization of the knowledge of the literature retrieval and literature reading, the class discussing mode of cultivating students' innovative thinking, the teaching evaluation method of literature reading course. The research results provide a reference for the cultivation of students' innovative ability.

Lacking communication and coordination between suppliers and retailers is the main cause of the shortage. The combination is simple bundle between two sides. For integrate back-end integration and supply chain, the two sides need powerful data analysis capabilities, this paper proposed trust evaluation indicators established a model of cooperation based on trust.

The MCU system is used to simulate laser signals and the signals received by avalanche transistors so as to conduct signal detection of actual circuit boards.With establishing a library of fault cases through the computer serial port, the MCU and the fault setting module can be based on to realize the fault simulation of actual circuit boards and conduct the training in fault detection and removal. The designed fault setting software and assessment software can be combined to assess the training effects of fault analysis, detection and removal. The developed prototype passes the test of training, showing good results and high training benefits

The laser divergence angle is an important parameter of laser beam quality. In order to meet the actual needs of engineering, a method for measuring the laser divergence angle was derived. The laser divergence angle was obtained by measuring the total laser energy and the laser energy behind the aperture. A measuring device was designed for validation. The experimental results showed that the result of the measurement was accurate with an error being smaller than 0.001 mrad . The entire measurement method and the system are simple, easy to operate and can quickly and accurately measure the laser divergence angle. They completely satisfy actual needs.
