如果离子固体有外力的约束，或者缺陷分布的不均匀，都会导致这样的偏离，因而会引起固体体积的改变，也就是说会产生内应力。
Such deviation generates volumetric change in the solid, which will result in mechanical stresses if the ionic solid is under mechanical constraints, or if the defect distribution is not uniform.
型挡墙，冲击区体积较小，钢液混合不均匀，钢液在整个中间包内的平均停留时间较短。
The pound region volume of the baffle C type is still too small, so the liquid steel can't mix sufficiently, and the average residence time in the tundish is short.
另外，炭黑粒子分布的不均匀性导致了海绵的体积电阻率较高。
The uneven dispersion of CB in foam results in higher volume resistivity.
如体积变化不均匀即体积安定性不良，容易产生翘曲和开裂，降低工程质量甚至出现事故。
Such as volume change uneven or volume stability, prone to warping and cracking, reduce the engineering quality and even an accident.
大核仁电子密度较高，质地不均匀，有时有一个体积很大的核仁泡位于其中。
The larger nucleolus was higher in electron-density, but the inside structure was not even, sometimes there was a very large nucleolar vacuole in it.
颗粒在管内的浓度分布是不均匀的，随颗粒的体积分率和流型的变化而变化；
The distribution of particle concentration in pipe is unequality and the unequality degree varies with the cent of volume and regime flow;
颗粒在管内的浓度分布是不均匀的，随颗粒的体积分率和流型的变化而变化；
