英文: And it is indicated that the corrosion residual life of the pressure vessel and pipeline shouldn't be calculated with normal distribution model since the coefficients of variation
of maximal corrosion depth and corrosion rate are often more than 0.2.
中文: 最后指出最大腐蚀深度和腐蚀速率等参数的变异系数往往大于0.2，因此不宜用正态分布模型进行压力容器与管道耐腐蚀剩余寿命的计算与分析。 更详细...
英文: As even a variation
in one item leads to corresponding construct variation
s, without the other indicators necessarily having to vary too, this construct consequently has a formative structure (Diamantopoulos/Winklhofer, 2001).
英文: As long as the truck is moving in a straight line, the ring gear, differential gears, and drive axles turn together without variation

英文: Biological variation
resulting from recombination, mutation, and selection.
中文: 生物多样性来自于基因的重组、突变、和筛选。 更详细...
英文: Both experimental and calculated results on variation
of groove depth with impress depth have been compared, resulting in that the two were in accordance with each other hence correct and believable numerical results.
中文: 最后对槽深与压痕深度的关系问题进行了数值模拟与实验结果对比，二者符合较好，说明数值模拟给出的研究结论是可信的。 更详细...
