The results show that when the shearing force is small, this model in the paper can be used well to study the relationship between the force acting on the brim of the pillar and the displacement of the top pillar.

算例结果验证了对于剪切变形较小的情况，考虑剪切的杆模型在反映杆端力和位移关系方面是正确的，描述反复加载条件下的杆本构关系是可行的。

It has a smaller head, shorter shaft than the driver and a loft of 15 degrees.

他的杆头相对开球杆小一些，杆身稍短，干面角度为15度。

A new special economical experimental unit which applies to the R717 recurrence system of the screw compressor with the economizer has been designed and set up. The experiential results of the single stage recurrence and recurrence with the economizer, such as refrigerating capacity, shaft power, volumetric efficiency etc, under different conditions are got from the experiments. The author analyze and the calculate results of theory in this paper.

建立了独特节能的R717工质带经济器螺杆制冷循环系统的试验装置，通过对所研究压缩机的试验测试，得到了普通单级螺杆循环和带经济器螺杆循环在各种工况下的制冷量、轴功率、容积效率、相对补气量、中间压力等数据，并与了本文理论计算的结果进行了比较分析。

Start stem O-ring seal over stem, then press into position as handle is pressed down over stem.

从阀杆上的阀杆O形环密封开始，然后在手柄安装在阀杆上后，将其压进手柄的位置上。

To meet the demand of higher built-up rate ,single-bending screw drill tool with large angle is used during the drilling of the moderate-and short-radius horizontal well.

钻中短半径水平井，在采用弯角较大的单弯螺杆钻具以满足高造斜率的需要时，由于套管内径较小，螺杆钻具钻头处位移比较大，螺杆钻具能否顺利通过直井段是钻中短半径水平井面临的一个重要问题。

Therefore, the pump body with the outer surface of screw and screw and screw more space should be as small as possible.

因此，泵体与螺杆外圆表面及螺杆与螺杆间隙应尽可能小些。
