In common glass fiber reinforced polyolefine pipe, when the volume faraction is less than the critical value, the glass fiber can not act as reinforcement, on the contray, it would reduce the whole intensity of the compound material. However, when extruded in combined stress field, the extend intensity of the compound system increases when the volume fraction of glass fibers is less than the critical value. When the glass fiber volume fraction is higher than the critical value, the required glass fiber volume fraction of compound fibers extruded in the combined stress field is less than theory value.

一般玻璃纤维增强管材在常规挤出时当添加的玻璃纤维体积含量小于临界体积分数(当添加的玻纤的复合体系拉伸强度等于基体聚合物材料的拉伸强度时的玻纤体积分数)时，玻纤起不到增强的作用，反而会使复合材料的整体强度降低；但在复合应力场下挤出时，当添加的玻纤含量小于临界体积分数时，复合体系的拉伸强度不但没有降低反而升高了；当添加的玻纤含量大于临界体积分数时，复合体系要达到同样强度，经过复合应力场的玻纤增强管材需要的体积分数小于理论值。

There existed dual-critical effect of such organic retarders as sucrose and citrin on cement hydration. First, when the amount was relatively low, cement hydration was delayed.

蔗糖、柠檬酸对水泥水化历程的调控作用存在双临界效应：一、在掺量较低时，表现为缓凝效果，当掺量较大时，则表现为促凝作用，但是浆体长时间不硬化；二、缓凝效果存在临界掺量值，低于临界值时，缓凝效果随掺量增加而增加，超过此临界值时，缓凝效果随掺量增加而下降。

For the entire subaqueous delta, accurate calculations for the critical value will depend upon a sound understanding of the sediment retention of the deltaic system.
