Laser technology is a highly advanced field. It requires a certain level of theoretical knowledge and practical skills to be applied to practice. Therefore, the research on the construction of a laser intelligent equipment teaching base (LIETB) jointly built by schools and enterprises will be studied. First, the necessity of constructing a LIETB from three aspects is given such as the characteristics of the LIETB, the importance of constructing the LIETB, and the significance of the school-enterprise joint construction model for the teaching base. Secondly, a practical plan for the construction of a LIETB is proposed. Finally, the evaluation methods and indicators for the practical effects of the school-enterprise joint construction of the LIETB are improved from two aspects, such as teaching effectiveness and employment situation evaluation methods. This study is of great significance for improving students’ practical environment and skill training, further enhancing the quality and quantity of laser intelligent equipment(LIE) application talents, promoting industry-university-research cooperation, and promoting the development of related industries.

Velocity factors are important parameters to determine the efficiency of turbine stages, and it is necessary to systematically study the effect of decline in velocity factors on stages efficiency under off-design conditions. In this paper the definition of the sensitivity of the velocity factors is proposed and effect of each parameter on the sensitivity is analysed. A simplified off-design model was also established to study the change of sensitivity of a governing-stage and pressure stage under the varying mass flow conditions. The results show that for the calculated turbine, the nozzle sensitivity of the governing stage is always greater than the blade for off-design conditions, and the efficiency of the nozzle in the governing stage should be emphasized. While the sensitivity of the pressure stage is related to the flow rate, it is more meaningful to improve the blade velocity factors in large mass flow conditions and it is reverse for low mass flow conditions. These findings will be meaningful in the optimization of turbine operation and design

With the rapid development of automation control technology, the majority of enterprises have begun to introduce automation equipment, but in some photovoltaic cell production in the enterprise, for the crystal silicon pile of temperature control in the process is still in the traditional way of manual control, this way of temperature control for the employee’s personal safety demand is higher, there is a certain risk. Aimed at this problem, this paper designed a crystal silicon velvet temperature control system based on MCU, the system consists of DS18B20 temperature sensor, 51 single chip microcomputer, sound and light alarm system, LCD1602 display module and motor drive module, the implementation of the system of velvet groove temperature monitoring, to ensure that the quality of the crystal silicon cell, through the simulation test system is stable, reliable and has certain practical application and popularization value.
