查询词典 Poisson ratio

Through the analysis of the increment, storage and configurative conditions in three industrial of agricultural and husbandry areas of Inner Mongolia,we calculate the participant factors'efficiency and construct economic model of the optimized configuration. The thesis points out that now the ratio of human resource of the optimized configuration factors in Inner Mongolia agricultural and husbandry is not at the best ratio point.

首先，从农牧区人力资源的增量、存量和在三次产业中的结构配置状况分析了内蒙古农牧区人力资源的现状；其次，利用线性回归的分析方法，对农牧区各投入要素对经济增长的贡献进行了测算，分析了影响农牧区人力资源配置效率的因素，并构建了农牧区人力资源优化配置计量模型，据此分析得到：内蒙古农牧区物质资本与人力资本投资比例位于最佳比例点附近，且大于最佳比例，需要通过增量调整来实现产出最大化。

The sulfate-reducing-bacteria were immobilized in polyvinyl alcohol to treat wastewater containing zinc. The effects of different crosslinking reagents on the conglobation, cohered efficiency of the carbon source, reduction ratio of sulfate, removal ratio of Zn, and COD of drainage were considered.

摘 要：以聚乙烯醇为包埋介质，对硫酸盐还原菌进行固定化处理；以含锌废水为处理对象，考察不同交联剂对成球性能影响、营养源内聚效果、硫酸盐还原效果、锌离子去除率和出水COD等因素。

Results indicate that in lauric acid and toluene quality ratio of 1: 2, R12-1.0G of Congo red transfer rate of 84.26%; as the R12-1.0G concentration increases, dye transfer of Congo red ratio increases, this experimental results and guest molecules of chemical structure.

结果表明：在月桂酸与甲苯的质量比为1：2时，R12-1.0G对刚果红的转移率达到84.26%；随着R12-1.0G浓度的增加，染料刚果红的转移率也随之增大，这一实验结果与客体分子的化学结构一定的关系。

eccentricity：释义 eccentricity 离心率椭圆的离心率即是指椭圆上点到焦点的距离与到准线的距离的比值。

In the first stage, the ratio of endogenesis GA3 to IAA in new corm rised on the whole, the ratio of IAA to ZR in new corm and cormel was rather low, the case of ABA to GA3, ZR and IAA was quite short.

籽球形态建成初期，新球内源GA3与IAA比值整体表现为上升，新球和籽球IAA相对ZR含量较低，ABA与GA3、ZR和IAA比值较低。

A counter argument, for example, is that China's investment ratio is actually not that high compared to its saving ratio.

但是该说法可能忽略一个重要事实，即中国的储蓄率不光全球最高，而且历史罕见。

Based on the EDF strategy, an adaptive dynamic criticalness algorithm was introduced to reduce scheduling miss ratio. In order to lower the task missed deadline percentage and make sure the success of scheduling ratio of critical tasks, the group tasks and the selection scheduling strategy based on the judgment function were adopted.

在优先级调度策略的基础上，引入自适应调度策略来降低调度错失率，采用任务分组的方法，通过判断函数动态地选择调度策略，利用可达截止期优先来降低任务错失率，保证了全局优先级高的任务的调度成功率。

The factors affecting water absorption were studied, such as mass of initiator and cross - linker, mass ratio of starch and monomer, mass ratio of acrylic acid and acrylamide.
