查询词典 variation method

In the auto-body assembly process, the sound joint configuration would reduce and/or eliminate assembly variation propagation between parts, because rational allocation and design of joint configuration enable to adjust assembly process locators to achieve slip joint absorb or compensate the variation accumulation to improve the assembly robustness, therefore, the paper study joint type design and configuration and describe a multi-station auto-body assembly propagation model.

在车身装配过程中，良好的接头设计可以减小甚至消除零部件间的装配公差的传播，而且合理的接头配置方案有助于装配偏差的减小与装配过程的稳定性，因此论文详细分析了接头类型设计与接头配置，并介绍了多站点车身装配偏差传播模型。

A probability calculation formula used for the cavity dimension of injection mold is derived on the basis of analysing the variation rule of plastic shrinkage rate, and a quantitative relation among the variation of plastic shrinkage rate, plastics dimension tole-rance, manufacturing tolerance and wear allowance is discussed.

文摘：在分析塑料收缩率波动规律的基础上，导出了注塑模成型零件工作尺寸的概率计算公式，讨论了塑料收缩率波动范围、塑件尺寸公差、制造公差以及修模裕磨量之间的关系。

Polymorphic loci, polymorphic frequencies, Nei's index of phenotypic diversity and Shannon index were 228, 62.81%, 0.2781, 0.4092, respectively, among Changjiang population, and 269, 74.10%, 0.3077, 0.4493, respectively, among Minjiang population. The results suggested that the two East Sea eel populations had abundant genetic variation, and the Minjiang river population was lower than the Changjiang river population, which indicated that high levels of genetic variation existed in the natural populations of Chinese Anguilla japonica.

In the increase density 0.05, 0.5mgkg-1 scope, the sea cabbage average increase returns-ratio is 85.1%~93.3%, the coefficient of variation is 5.39%~12.05%; The soil average increase returns-ratio is 90.9%~98.5, the coefficient of variation is

在添加浓度0.05、0.5mg·kg-1范围内，甘蓝平均添加回收率为85.1%~93.3%，变异系数为5.39%~12.05%；土壤平均添加回收率为90.9%~98.5，变异系数为

Results show that in recent years, the summer rainfall in Harbin displayed the most apparent cyclical variation on a 29-38-year scale, the largest modulus, and the strongest energy; and the summer rainfall in Nenjiang did an obvious cyclical variation on a 19-30-year scale, and its energy value is quite large. Both the two cyclical variations showed a trend of being stronger in energy with the time.

结果表明：哈尔滨近年来夏季降雨在29~38a尺度周期变化最明显，模值最大，能量最强；嫩江夏季降雨在19~30a周期变化较强，能量值较大；2个周期变化都具有随时间推移能量进一步加大的趋势。

The results show that the variation in elevation angle of roof beam can be controlled by the equilibrium jack in moving support and the stress at different parts can be adjusted according to the variation of the support load in coal caving process, greatly improving the adaptability of the 2-leg shield support in top-coal caving working face.

分析结果表明，通过平衡千斤顶可以控制移架过程中顶梁仰角的变化，并可调节支架各部位受力以适应放煤过程中顶梁外载的变化，从而提高了两柱式支架对放顶煤工作面围岩活动规律的适应性。研究结果对于现场操作及新架型的改进都有一定的指导作用。

For the variation of short period of astronomical factors, whether for local time or local sidereal time and lunar phase there is the phenomenon of occurrence of concentrating a interval time for the earthquakes. For the short variation of earth rotation this phenomenon is clear; either the earthquakes occur in most fast or in lowst of earth rotation.

对于天文因素的短周期变化，无论是对于地方时，地方恒星时与月相，都有集中发生在某一段时间的现象；对于地球自转的短周期变化更是比较明显，要么发生在其变化最快时期，要么发生在其变化的最慢时期。

One QTL for SRLD was detected on chromosome 12 with about 12%variation, and two QTLs for SRLD were detected on chromsome 2 and 11, and about 13.37% and 18.23% of total phenotypic variation were explained.

这与以前的报道所得到种子根长相关的 QTLs 所在位点不一致，这种不一致性可能是由于不同遗传材料及不同实验条件的差异所致，也可能是因为表型测定时期不同所致。

The variation is due to the variation of the magnetic reaction.

这些变化是由不同磁性的永磁颗粒的相互作用造成的。

As the results suggest that, during the period of 1800～2005, the 82-year and 48-year quasi-periodic components are available for the secular variation of dipole magnetic field, which are not directly related to the periodicity of the length-of-day variation.

结果表明，1800～2005年期间，偶极子磁场长期变化有82年和48年准周期分量，它们与日长变化的周期没有直接关系。

"The operators will suffer a temporary decrease in the number of consumers and short message services as people may not like having to provide their ID cards for a phone number," Xu Junqi, vice-dean with the Policy-Making Institute of the Telecommunications Research Centre under MII, said yesterday.
