The function o f the assembling of the injection mol ding screw head is very important for press ure control during molding operations . 对于成型过程的压力控制,注射成型螺杆头组件的作用非常重要。
Lateral earth pressures acting on the wall could be predicted from the Rankine active earth pressure theory with the undrained assumption in the short term. 对土压力结果的分析表明，作用于圆筒岸壁的侧向土压力可依据朗肯主动土压力理论，根据筒后土体的不排水强度进行预测。

The figure of Rankine active earth pressure in clayey soil is corrected.And the cohesion stress region in it is conformed.Various incorrect statements of cohesion on that part are put right. 更正了粘性土朗肯主动土压力分布示图,更改其间“拉应力”区的提法,提出了广义粘聚力概念。
