In a special circulating system with high velocity flow, boundaryshear stresses in clear water flow, aerated flow and sediment laden flow are measured.
在高速水流循环系统中，用自行研制的剪切力传感器分别量测了清水、掺气水流及挟沙水流壁面上的剪切力；

It is found that the initial slip length controls the slip behavior at small shear rate, but the critical shear rate controls the boundary slip at high shear rate.
研究发现初始滑移长度对低剪切率下的滑移行为起主要作用，而临界剪切率决定了高剪切率下的边界滑移程度。

Series solutions were derived for the in-plane strain, deflection and bending strain that satisfy the simplified boundary conditions to calculate the shear lag coefficient.
