z-coordinate meaning in English

z坐标

They are not computed by the depth of the object , or z - coordinate
雾化效果不是按对象深度或z坐标计算的。
All calculations are in the hypothesis of " ideal slot " , that is the slots are so narrow that longitudinal field along the slots can be ignored and all fields are independent about the z - coordinate
在当中忽略缝隙口面场随缝隙倾角变化而在z方向上产生的变化? ?即认为场量与z无关。在此前提下可以将三维问题简化为二维问题，用边界元素法直接求解。
The nonlinear dimensions are decomposed into several sets of linear dimensions , and the 3d dimension chain is projected into dimension chains of three individual directions , namely , x - coordinate direction , y - coordinate direction and z - coordinate direction . every individual dimension chain is checked with an improved algorithm of dimension testing , and the conflicting dimension is adjusted by the mechanism of dimension rank and the principle for adjusting the dimension model
介绍了各种非线性尺寸虚拟分解成线性尺寸的方法，将空间的尺寸链投影成x 、 y 、 z三个方向上的单向尺寸链，在此基础上根据改进的尺寸冗余判断算法对各单向尺寸链进行尺寸封闭检查；引入尺寸的优先机制和尺寸模型调整的原则，据此对冲突的尺寸进行调整。
