Particles shorter or narrower than 0.04m seem to not be drawn at all... UNLESS at some point in the particles life it is both wider and taller than 0.04m, your milage may vary.

粒子效果，当短窄于0.04m，这是不充许的，除非粒子效果中的一些点包括宽和高于0.04m，你的milage可能会变大。

The results showed that the irradiation of mixed high-energy particle field inhibited mitoses and produced various chromosomal aberrations such as micronucleus, chromosome bridges, circular chromosomes and dissociative chromosomes in root tip cells of wheat with significant dose-effects.

混合粒子场与γ射线诱发的微核畸变率和染色体畸变率均存在明显的剂量效应，但混合粒子场的损伤效应明显高于γ射线。

Mullers breakthrough was to find a way to date how long ago any particle was melted--meaning he could build up a picture of whether the moon gets a constant barrage or suffers spells of intense bombardment.

马勒的突破是他找到了一种确定粒子被融化的年代的方法，这意味着他可以确立这样一幅画面，即月球是受到接二连三的轰击还是经历了间歇性的强烈的粒子辐射。

These galaxies are located in the direction of the constellation Virgo, and the radiation consists of particles called muons, which are so powerful they can penetrate about 2.5 kilometers of sea water or 900 meters of rock--enough to reach just about every living thing on Earth and damage its DNA.

这些星系位于Virgo星座的方向，并辐射一种被称为&介子&的粒子，这种粒子有着强大的贯穿力，它们可以穿透大约2.5公里的海水或者900米的岩石，这已经足以到达并破坏或地球的任何一种生物，并损坏它们的DNA。

The reacting cosmic particles producing nuclides primarily include secondary fast neutrons, thermal neutrons and slow negative muons. Due to the differential special distribution of these reacting particles, the production rates of Cosmogenic nuclides at different latitude, altitude and depth are different.

产生宁宙成因核素宇宙射线粒子主要是次生快中子、热中子和负慢介子，由于这些宇宙射线粒子在空间分布上的不同，地球上不同纬度、海拔高度和深度处的宇宙成因核素生成速率也表现出较大的差异。

Under the excitation of 488 nm light beam of argon ion laser source, single suprahelical species could be observed with the aid of a common microscope due to the strong scattered light emitted by the suprahelical species. By capturing the RLS images of the single suprahelical species with a cooled charge coupled device camera, and analyzing the RLS data, herein an RLS imaging method of DNA was proposed based on the linear relationship between the counts of suprahelical species in the detection focus plane and the concentration of DNA in nanograms.

在488nm 氩离子激光光源的激发下，单个超螺旋聚集体的散射光可以通过普通显微镜观察到，用冷却型电荷耦合器对此单个粒子的RLS信号进行成像和分析，发现在聚焦平面上检测到的超螺旋粒子的个数与溶液中纳克级的DNA浓度成正比，基于此建立了一种测定DNA的方法。

We use the single particle model and find a new nonlinear resonant acceleration criterion analytical: nw(1)+mw(2)=NW, m,n,Nare integers, w(1,w(2), W are the frequency of the two waves and the charged particle cyclotron respective,this result can be extended to the multiple waves ,we make numerical simulation and numerical results are consistent with the analytical results. This paper consists six chapters.

因此本文从基本的情况开始，以两个静电波与磁化等离子体相互作用问题为研究出发点，通过多标度展开的理论方法，求解带电粒子的运动方程，得到的一个新的非线性共振加速条件：nw(1)+mw(2)=NW，（m，n，N为整数，W，w(1)，w(2)分别为带电粒子的回旋频率以及两个静电波的频率），该结果可以推广到多个静电波作用于磁化等离子体的情况，随后通过数值计算证实了解析结论的可靠性。

When exterior factors such as the addition of electrolyte to colloids lead to the formation of lower symmetry aggregates such as trimers and tetramers, HRS signal is enhanced, but it is required that the aggregation of particles is compact and irreversible.

当外界因素导致的胶体中形成低对称性的粒子聚集体时，对HRS信号有增强作用，但要求粒子间的聚集是紧密的和不可逆的。
