查询词典 particles

By using the method of linear regress, the relation between the cosmic ray intensity of the OULU neutron monitor and the differential fluxes of space energetic proton and ion during quiet time has been studied. The differential spectrum of interplanetary particles with high energy is also calculated through the intensity of neutron at the ground level.

采用线性回归的方法研究了太阳活动平静时期空间高能质子和重离子微分通量与地面OULU宇宙线台站中子强度之间的相关性，利用地面中子强度数据来反演空间高能质子和重离子通量。

The morphology of T-ZnO has a very small change at a low sintered temperature. The needle of T-ZnO sublimated vanished with the increase of sintering temperature because of Joule-Thomson effect, and ZnO particles and massive ZnO appeared.

在低温下烧结(50oC)，四针状纳米ZnO的形态改变不大；随着烧结温度的升高，由于汤姆逊效应，针尖升华，导致针体部分逐渐消失，颗粒状、块状ZnO逐渐增多。

This paper introduces the study of characteristics of electric charge carried by dust particles due to the Millikan testing method.

对颗粒电荷测量方法进行了研究，将密立根方法应用于自然状态下尘土颗粒电荷的测量。

The study of characteristics of electric charge for charged dust particles by the Millikan testing method is introduced.

结果表明：尘土颗粒所带电荷的变化趋势可用一元三次多项式表示，电荷分布呈现带状区域，其所带的平均正电荷高于所带的负电荷。

While observing mammalian cells with an electron microscope in 1988, Olavi Kajander and his colleagues at the University of Kuopio in Finland observed ultrasmall particles inside many of the cells.

Olavi Kajander和他的同事1988年的时候，在芬兰的库奥皮奥大学曾经在电子显微镜下观察哺乳动物的细胞时曾经发现极小部分的外在微生物。

In the days of sailing vessels the crew were afraid they would be becalmed on the ocean.

在使用帆船的时代，船员们担心他们会因为无风而无法在海洋上航行。

As long as foreign donors pay the PA's salary bill, few expect a new intifada.
