查询词典 distances

Poisson line technique is a method of generating a straight line by diffraction for high precision alignment,which can keep the center of Poisson spot in this line at long distances (several tens or hundreds of meters).

Poisson斑的中心可以在很长的距离内保持与轴心共线因而能实现高精度的对心瞄准，这一技术被称为Poisson线技术。

为了避免这种情况，玻璃的顶部与屋檐的底部应至少保持层高H的30%的距离。

Determining the distances and ages to globular clusters like M2 constrains the scale and age of our entire universe.

测定类似M2一样的球状星团的距离和年龄将限定整个宇宙的年龄和规模。

The mean square end-to-end distances and their components,as well as the mean square radius of gyration and their distributions were calculated at different temperatures.

计算机模拟得到了端基附壁链的均方末端距及其分量，均方回转半径及分布随温度的变化。

This kind of throwing motion can be used at short distances when a quick spin is needed, but is not very useful for throws longer than a half-turn.

当距离较近，需要较快的转速时，这种情形是有用的，但当投掷距离比半周投掷的合适距离远时，就不那么管用了。

Take the trouble to measure your half-turn distance with some care, because it's used to calculate your basic half turn, a handy unit for measuring all knife throwing distances.

在测量自己的半周投掷距离时要用心，因为这将成为衡量所有投掷距离的一个方便的单位。

This seems also like a long ways away to be causing this kind of damage; but considering Niburu is 5 times the size of earth, has 25 times the mass, and is 100 times more dense than earth; in fact it is one of the most devastating distances Niburu could be and here's why, according to Mark Hazelwood.

那看起来好像是一个很长的距离，不会引起这种损害，但考虑到nibiru是地球的5倍大，质量是地球的25倍，密度比地球大100倍，事实上，这个距离是nibiru最能造成毁坏的距离之一，那也是为什么Mark Hazelwood会说"一个巨人从旁通过"。nibiru过境仅会偶尔造成极移，但它通过时总是给地球带来严重损坏，在地球上留下了极具毁灭性的印记。

The genetic distances to resistant gene are 9.6 cM and 10.4 cM, respectively. The resistance to sorghum head smut physiological race 3 may be controlled by two mutual independent nonallelic genes, and there is interaction between them. It is found that molecular markers are easier to find in B population than R population during the screening of SSR markers. It may show the different resistance mechanism between restorer line and maintainer line.

高粱对丝黑穗病菌3号生理小种的抗性可能受2对彼此独立的非等位基因控制，并且基因之间存在着互作；筛选SSR标记时发现，高粱抗丝黑穗病基因的分子标记较易在保持系群体中找到，在恢复系群体中DNA片段多态性较少，表明恢复系和保持系在抗性机制上可能存在差异。

At the shorter distances the .338 Lapua is too powerful, and unless you need a deep penetration, the Mini Hecate wold be an overklill choice.

在短距离的0.338拉普尔是过于强大，除非你需要一个深穿透，迷你赫科特泽沃尔德是overklill的选择。

The temperatures of the dust with different properties, dimensions of grain and heliocentric distances have been obtained.

得到了性质不同，颗粒大小不同，日心距不同的尘埃的温度。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
