The electron line itself in a Feynman diagram represents a "bare" electron ,whereas the real observable particles are the "bare" particles "dressed " by these virtual processes,the so-called"self-energy" terms which contribute to the mass and charge of the electron that the experimentalist measures.

一个 Feynman 图表的电子线本身表现"赤裸的"电子，然而真正的观察得出的粒子是被这些虚拟的程序穿着的"赤裸的"粒子，那所谓的"自己的-能源"成为块和实验者测量的电子费用的因素期限。

In addition, through plotting the hydrograph of mean annual and natural yearly runoff and the residual mass diagram of frequency factor from 1919 to 2002 in Sanmenxia Station, 2 continuous low water periods from 1922 to 1932 and from 1990 to 2002 are obtained.

通过绘制多年均值和天然年径流量过程线以及模比系数差积曲线，得出黄河三门峡站1919～2002年系列中存在1922～1932年和1990～2002年两个连续枯水段。

Through a study of the cases of transit signaling system improvement in the world, this paper introduces the development of CBTC-MB, which is compared with the traditional Fixed Block, the principle, the functional block diagram and the technical standard of CBTC-MB, holds that this technology will be further developed and applied in urban mass transit.

通过国际上城市轨道交通列车控制系统发行的案例，介绍了移动闭塞在国际上的发展概况。比较了基於通信的列车控制的移动闭塞列车控制方式和传统闭塞方式之间的不同。介绍了移动闭塞的工作原理、组成及相关的技术标准。指出移动闭塞和CBTC必将在城市轨道交通中得到发展和应用。

In this paper the conflicting discussion of scholastic view-point on seepage force which has lasted many years is stated. Then the physical concept of seepage force and its related forces including the resolved two components (a seepage force and a buoyant force) from seepage resultant force, the transformation between the seepage force and boundary pore water pressures, schematic diagram of forces acting on unit soil mass and the mathematic proof by Green theorem are described.

追述了多年来对渗透力学术观点的争论，并再就此问题论述了渗透力的物理概念及其与之相关的各力（包括渗流作用合力及其分解成的两个分力，渗透力与周边孔隙水压力的转换关系及各力作用在单位土体的图示；从数学上引用格林公式，证明土体表面水压力与土体本身渗透力之间的转换关系。

The ion motion in such an electric field is derived,and the stability of ions is presented in the a-q diagram which is commonly used for sinusoidal wave quadrupole mass spectrometry in association with the solution of Mathieu Equation.

本文推导了离子在矩形波四极场中的运动规律，并以常用于正弦波四极场的马绍方程参量a，q来表出离子的稳定性。

As to the high polarity, high boiling point resultant—trimesic acid, the analysis methods of infrared spetrum, gas chromatography-mass spectroscopy, vapour-phase chromatography, acid number titration and so on are seperately used to characterize its property. Infrared spetrum and gas chromatography-mass spectroscopy are used to have a qualitative analysis on the resultant and are compared with the stand diagram. Sulfuric acid-methanol esterification and rapid esterification are used to prepare the trimesic acid trimethyl-ester and have a FID quantitative analysis. So that we make sure the purity of trimesic acid in the resultant and also we have an acid alkali titration on the resultant to get its acid number, in order to verify the purity of trimesic acid in the resultant.

对于高极性、高沸点的固体产物均苯三甲酸，分别采用红外光谱、气质联用、气相色谱、酸值滴定等分析手段进行了表征：利用红外光谱、气质联用的方法进行产物的定性分析，并与在同一仪器、同一条件下做出的标准谱图进行比对；采用硫酸-甲醇酯化法和快速酯化法制备出均苯三甲酸三甲酯，对其进行气相色谱FID定量分析，进而确定固体产物中均苯三甲酸的纯度；用酸碱滴定法确定固体产物的酸值，以对固体产物中均苯三甲酸的纯度进行验证。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
