工作脉动器引起的动态效应导至它的极值测力机构的示值和试样承受负荷的偏差。在大多数讲述这个问题的著作中[1-6],都注意研究分配极值的阀门(分流)原理,不可认为是非常接近和精确的。但是,目前正寻求实际的应用以及活门 The dynamic effect caused by the working pulsator leads to its indication of the extreme force-measuring mechanism and the deviation of the specimen from the load. In most of the writings on this subject [1-6], attention was paid to the study of the principle of valve distribution (shunting), which can not be considered very close and precise. However, the practical application and the door are currently being sought
