several typical successful cases are introduced in this paper, and the permissible value of displacement under service load is studied which can be taken as reference for other similar projects.
when choosing a value for r6, ensure that q2's base-emitter voltage is less than approximately 0.5v at the maximum permissible value of the load current.
选择r6的阻值时要确保在负载电流的最高允许值的条件下,q2的基极-发射极电压大约低于0.5v。
these data are analyzed and compared to stipulate sound particle velocity and permissible value of wall rock. the engineering blasting parameters and timbering measures are suitable for th…
经与规定的质点振动速度和围巖变形相对允许值比较、分析,认为该工程爆破参数和支护措施是适宜的。
it is pointed out that the peak shear strength may be larger then the permissible value of the peak shears.
