Radiological studies using this facility found that only 20%of irradiated cells were killed by a single particle, and the dose response curve for nuclear irradiation with exact number of particles was not significantly different from the curve obtained using average particle traversals of broad-field exposure.

应用该微束装置的放射生物学研究发现单个α粒子仅导致大约20％的致死率，其存活率曲线类似于用常规照射获得的平均粒子存活曲线。

Surface tension of nanometer particle La(1-x)Sr_xMnO_3 can be reduced remarkably that adding un-ionic surface-active agent. It prevent colloidal particle from growing up and original particle reuniting, thereby minish effectively particle size of oxide and improve its dispersing.

添加非离子表面活性剂可以显著降低纳米微粒 La_(1-x)Sr_xMnO_3的表面张力，防止原生粒子团聚和胶体粒子长大，从而有效地提高粉体的分散度并减小粒径。

In this paper, it is shown that the increment of the plasma confinement time without consideration of radiation losses is a good scale for evaluating the plasma confinement improvement during the L-H like transition induced by electrode bias in tokamaks, if the ratio of the radiation power to the total loss power in the transition changes evidently.

辐射下降表明进入等离子体的中性粒子通量减少。这是中性粒子再循环的减小而造成的。同时，边缘密度和边缘温度下降，中心温度上升，约束得到改善，能量约束时间增加。径向电场是控制托卡马克等离子体从L模过渡到H模的关键因素。如果径向电场足够强，极向ExB旋转产生很大的剪切，剪切能够抑制边缘湍流1j。

If tachyons were shown to exist we might have to rethink the idea of causality, since they would appear in some circumstances to go backwards in time, so that to a hypothetical observer the emission of a tachyon would appear to be its absorption.

假如超光速粒子真的被证明是存在的，我们需要重新构想一下因果关系的概念，因为它们在某些情况下会在时间中逆行，所以对一名假想的观察者来说，超光速粒子的辐射将以吸收出现。

It's a prototype tachyon accelerator, built to generate faster-than-light particles.

这是一个超光速粒子加速器的原型机，用来制造超光速粒子。

However if h is allowed to evolve freely to maintain a constant number of neighbours in SPH summations , such unwanted effects can be avoided and accuracy improved .

若随时调整h的值使得SPH方法计算粒子的邻近粒子数总和保持不变，则可以避免这种有害的影响，使准确性得到提高。

When particles are set to Sprites, an image or sequence can be mapped onto the individual particles.

当粒子被设置为精灵，一幅图像或序列可以被直接映射到独立的粒子上去。

The experimental results show that the erosion behavior is similar to that of brittle ceramic materials while the maximum erosion is found to occur at a jet angle of 90 degrees. The successive spalling of splats ...

结果表明：Cr3C2 NiCr涂层的冲蚀磨损呈现脆性材料的冲蚀磨损特征，在 90°冲蚀率最大；磨料冲击引起的裂纹沿涂层内粒子界面萌生、扩展并最终导致粒子剥落，是涂层主要的冲蚀磨损机制。

Meanwhile, it is also illustrates that the smaller chromium carbides have less restriction to formimg thin splats than larger ones, which beneficial to limit the size of pieces removed by impact of the sand particles, and the higher volume fraction of small chromium carbide may effect the erosion through enhancing interlamellar bonding of the splats which leads to increase the erosion resistance of the coating.

揭示了细小碳化物颗粒有利于获得扁平粒子厚度较小的涂层结构，可减小涂层冲蚀磨损过程中每次剥落的体积；较高含量的细小碳化物颗粒有利于提高涂层扁平粒子间的结合，从而提高涂层抗冲蚀磨损性吉臣。

Significantly different scalings of the mean IMF multiplicities with neutron,charged-particle,light charged-particle multiplicities,and Zbound are observed for the two reactions.

观察到两个反应系统中，中等质量碎片多重性、中子多重性、荷电粒子多重性与轻荷电粒子多重性之间的关联存在着明显的差别。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
