查询词典 variation

Variation of the grid spacing and attenuation factor was studied to get the best CoMSIA model.

This paper presents new data of electronic microprobe analvses on clinopyroxenes from the layers of picrite and associated basalt in this area. It is shown that the clinopyroxenes from the picrite are exclusively diopside, whereas those from the basalt are diopside and augite, suggesting a continuous variation in composition.

本文对该地区苦橄岩及其共生的玄武岩中单斜辉石的矿物化学成分进行了电子探针分析，结果表明，苦橄岩中的单斜辉石全部为透辉石，玄武岩中的单斜辉石种属有普通辉石和透辉石两类，但玄武岩中的单斜辉石成分呈连续演化关系。

To avoid or reduce re-analysis, we derived the augmentative matrix variation only in summation of the previous matrices time the outside-perturbed parameters by decomposing the element stiffness and mass matrix. The implicit function of amplitude about design variables such as cross-areas and lengths is changed into simplistic function about the perturbed parameters of design variables. Several methods for determining the value of perturbed parameters are detailed.

为避免或减少重分析，将有限元单元阵进行了分解变换组装，使振幅与设计变量如截面面积、长度的复杂隐函数关系转化为对设计变量摄动参数的显式关系，进而将设计变量摄动参数提取在分解后的几个常数刚度阵、质量阵之外，避免了在迭代求解过程中重组刚度阵与质量阵，较快地获得问题的解。

Experiment results demonstrated that EPS production by A. auricula was very sensitive to pH variation in submerged fermentation.

在此基础上提出了A.auricula发酵生产黑木耳多糖的两阶段pH控制策略：0—48h控制发酵液pH5.0，48h后控制pH5.5。

This spiral shape is unique. It is definitely not a variation of the aurora borealis - northern lights.
