查询词典 decrease in population

For the all classes of dies, if we analyse the fluctuate, tendency of increase and decrease and law which appeared in the die's whole life, we will find that the master of the error are changeless; the error that because the abrade of the cutter and impression will be as the cutter grinding times increased at the same time. And that will cause the error oversize gradually; and also have another part error are unconventional , unforeseen.

对各类冲模冲件误差在冲模整个寿命中出现的波动、增减趋向及规律等进行全面分析便可发现：冲件误差的主导部分是不变的；因刃口或型腔的自然磨损而出现的误差增量随冲模刃磨冲数增加而使这部分误差逐渐加大；还有部分误差的增量是非常规的、不可预见的。

So how to decrease the abrasion of bearings becomes one of the important researching subjects.

因此，如何减少轴承磨损是振动机构研究的主要课题之一。

The negative effect of this reinforcement is usually a decrease in impact strength and an increase in abrasiveness.

这种加强的负作用通常是抗冲击强度降低及磨损性增加。

Diagnosis and treatment at earliest can decrease the incidence of placental abruption and death rate of perinatal.

对病因进行早期诊断和治疗，可以降低胎盘早剥的发生率和围产儿死亡率。

The results showed that with temperature decreased, levels of endogenous hormone changed obviously,such as the increase of the content of Abscisic acid,and the decrease of Gibberellic acid.

结果表明，低温半致死温度降低的同时，脱落酸含量上升，赤霉素含量下降，尤其值得引起关注的是脱落酸含量与赤霉素含量的比值的变化表现出与低温半致死温度更密切的关系(R =- 0 992 0 )。

It was found that deficient or excessive soil moisture led to increase in abscission of squares and bolls and decrease in fiber quality.

研究发现，土壤水分不足或过大，均易造成蕾铃脱落增加和品质下降。

NiAl-Al2O3-TiC acted as transferring stress and supporting for protective layer. With increase of test temperature, decrease in strength and hardness of NiAl-Al2O3-TiC led to abscission and cracking of protective layer.

NiAl-Al2O3-TiC对保护层起到传递应力和支撑作用，随着试验温度的升高，NiAl-Al2O3-TiC强度和硬度的降低导致保护层的开裂和脱落。

The results show that moist milling using absolute ethyl alcohol as medium and higher rotational speed can effectively decrease the particle size of Mo.

实验结果表明：使用无水乙醇作为球磨介质进行湿磨以及提高球磨的转速都可有效的降低Mo颗粒的尺寸。

This finding gives a good explanation to some experiment results which were not understood previously, such as"additional temperature effects"meaning that the flashover voltages after air density correction still increase with the decrease of temperature, and the increment of AC flashover voltage over an insulating surface caused by increase of unit absolute humidity is abnormally high, etc.

根据这一发现，可以很好地解释以往无法解释的一些试验结果，如所谓"温度的附加影响"，即同一绝对湿度对应的工频闪络电压，经过空气密度校正之后，仍随环境温度下降而明显增加。

The absolute magnitude of the strain in the bulk of the wire is attenuated significantly along the width direction. At the wire center, the strain-modified direct bandgap increases with the decrease in wire width.

文章还具体讨论了量子线线宽对应变分布和带隙的影响，结果表明：沿线宽方向，应变的绝对值逐渐减小，并随线宽的增加而变大；带隙则随线宽的减小而增大。
