要避免因填充墙不均匀分布引起的薄弱层效应，最有效办法就是控制结构在薄弱层附近的侧移刚度比。

The results show that the main cause of the angular distortion of the lap joint is the non-uniform distributed inherent shear strain component that is vertical to the weld line and exists in the plane paralleling to the weld line.

结果表明：搭接接头焊接角变形的产生主要是由焊缝及其附近区域与焊缝平行的平面内垂直于焊缝方向上不均匀分布的固有剪切应变分量引起的。

With increasment ofE/N,electron average energy and probabilities of electric excitation,dissociation,ionization,dissociative ionization collisions are increased.

随着E/N的升高，电子平均能量升高，发生激发、离化、电离和离化电离碰撞的概率增大；非均匀分布的电场使分子获得更高的离化率，同时显著增强出射电子的能量。

By careful study to the deflection response of a hinged-fixed circular plate u nder concentrated impulse loading,the saturated impulse phenomenon in the proces s of response is discussed.

利用有限变形弹塑性连续体的最小加速度原理，建立了分析圆板动力响应问题的数值方法，并通过对均匀分布的脉冲载荷作用下铰支圆板位移响应的细致分析，探讨了响应过程中的饱和冲量现象，指出对于高载范围内的脉冲载荷，相应于最大变形的饱和冲量确实是存在的。

Gear drives: The tines evenly distributed on the gear serve the purpose of power transmission.

齿轮传动机构：它靠均匀分布在轮边上的齿的直接接触来传递力。
