查询词典 peak

The foundation of this system provides a good reference to promote the standardization and intelligence of the overhaul and maintenance of vacuum switches. This paper develops a special HF pulse power supply for internal pressure estimation, which achieves the output of HF-HV sinusoidal pulse wave whose frequency and amplitude can be modified respectively, and meets the design requirements according to the results of Simulink simulation and practical experiments. With the help of AT89S52, this paper designs an I~2C serial bus based signal detection system for peak value signal acquisition of HF pulse currents, which communicates with the upper computer by asynchronous serial communication for uploading the data. In the upper computer, a human computer interface is developed by Matlab software, whose functions are to do some computation and graphic display, such as calibrating the relation curve of vacuum degree and peak value of HF pulse currents, vacuum degree computation, and vacuum lifetime evaluation analysis basing on grey forecasting model as well as making relative suggestions.

3Though the variety of the biotite content in granite is not very important to the influence of macroscopic peak strength of granite, from the microscopic view, a range still a demand attractor that it affect, the peak strength of granite is the highest when the biotite content is about 5%.

3花岗岩中云母含量的变化对花岗岩宏观峰值强度的影响虽然不是非常显著，但是，从细观角度考虑，其影响的幅度还是需要引起注意的，在云母含量在大约5%时，花岗岩的峰值强度最高。

The variation of the mechanical properties, including peak stress, Young's modulus and poisson ratio of Gypsum Breccia, was obvious. The peak stress and Young's modulus were improved after drying. The mechanical properties were obviously affected by the natural water content.
