According to XRD analysis, the high concentration doping of dysprosium ions in Fe3O4 can not be obtained due to the difference of ionic radius, and Fe^3＋ ions are replaced by only a small amount of dysprosium ions.

通过X射线衍射分析发现，由于离子半径的不匹配，Fe3O4中稀土离子的高浓度掺杂不能实现，仅有极少量的稀土离子取代了Fe3O4中的Fe^3＋。

The characteristics of the MHD structure observed in the soft x-ray tomography are as follows. It is constructed with m=2 mode oscillation, so that the magnetic surface is made up of two islands. The structure of the magnetic surface is relatively stable. It rotates in the direction of the electron dia-magnetic drift, and the rotation frequency is the half of the oscillation frequency of soft x-ray signals.

通过SX反演图象分析，MHD型磁面结构的特点：一是m=2模的振荡构成，因而此磁面始终有两个岛组成；二是磁面结构相当稳定，在MHD放电过程中没有明显变化；三是磁面结构整体沿电子逆磁方向极向旋转，旋转的频率是软X射线测量的信号频率的一半。

In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).

扎采品表示，充有高能量的粒子（大多数太空射线都属于原子核，因此也就具有正电）应该会由于太空微波背景下（渗透到整个宇宙的大碰撞所遗留下的辐射）的光子碰撞而减慢速度。

A plausible charge distribution of Fe and Mo valence states is proposed, and the stability of the compounds is discussed. Polycrystalline samples of 〓(0.8≤x≤1. 5) are prepared by solid-state reaction at high temperature. The alteration of the relative content between Fe and Mo in 〓 exhibits a significant effect on the crystal structure and the ionic ordering of the compounds.

采用传统高温固相烧结反应法合成了非化学配比的双钙钛矿型〓系列化合物。X射线粉末衍射数据分析结果表明，非化学配比的双钙钛矿结构〓（0.8≤x≤1.5）系列化合物的晶体结构随着Fe含量x的变化在x=1.2附近有一个由四方14/mmm对称向立方Fm〓m对称的结构结构相变发生。

Phosphate porous starch and PVA were cross linked by methenamine and boric acid Crystal area was serious destroyed by esterification and cross linked. 6 Biodegradation experiment was carried out with soil-burying method.

5红外光谱和X-射线衍射的结构分析表明：在改性淀粉的羟基上引入了磷酰基团，并未破坏原淀粉的基本化学结构；交联剂在改性淀粉和PVA之间形成了C-O-C化学交联键；酯化和交联反应均有较强的淀粉晶区破坏作用。

In the computer vision analysis system of wood across compression,early wood cell,latewood cell,wood ray cell and resin canal cell were recognized and classified automatically byusing neural network technology,applying the function of network recognition and the learningfunction of self-organizing and self-adapting,and wood tectonics feature were taken down byinstructed-learning or uninstructed-learning.

在木材横纹压缩计算机视觉分析系统中，采用了人工神经元网络技术，并运用人工神经元网络的网络识别功能和自组织、自适应的学习功能，通过有导师或无导师学习来记忆所学习过的木材构造学特征，实现了对针叶材管胞中的早晚材细胞、木射线细胞和树脂道细胞进行自动地识别与分类。

The analysis of X-ray diffraction and scanning electron microscope energy dispersion spectra show that the primary hydrolysis products of antimony pentachloride and its hydrochloric acid solution are amorphous antimony oxide rather than SbO2Cl.

X射线衍射和扫描电镜能谱分析表明：五氯化锑及其盐酸溶液的初始水解产物不是SbO2Cl，而是一种非晶态锑氧化合物；随着水解母液酸度的降低，五氯化锑溶液水解产物陈化五天后的晶型由非晶态向晶态变化；五氯化锑溶液水解产物经无水乙醇洗涤后水解产物仍为非晶态，而经蒸馏水洗涤虽主要为非晶态，但有少部分结晶的Sb2O5·4H2O晶体存在。

Results of meausred radioluminescence spectra show that energy transfer mechanisms occurring from Gd3+ cations towards Tb3+ emssion centers as well as the cross relaxation among Tb3+ cations within the certain concentration range exert tremendous effects on the emission intensity of glasses.

Tb3+离子的掺杂浓度范围为1－5 mol %。玻璃样品的X射线激发发射光谱结果显示，发生在玻璃基质中由Gd3+离子向发光中心Tb3+离子的能量转移机制以及在一定浓度范围内Tb3+离子之间的交叉驰豫过程对玻璃的发光性能有重要影响。

Smith has indeed shot Jones; but fuller inquiry shows that he did it unintentionally: perhaps he shot at a bird not foreseeing that Jones would suddenly and without warning step into the line of fire, or that the bullet would ricochet off a tree: or perhaps he thought on good grounds that the gun he was playfully pointing at Jones was unloaded.

史密斯的确枪杀了琼斯。但更为全面的调查表明，他是非故意这样做的：也许他是在打鸟，而未料到琼斯会突然毫无预兆地闯入射线，或者没有想到子弹会从树上跳飞；也许他有充分根据认为，他开玩笑地对准琼斯的枪没装子弹。

And the X-ray imaging tube with this new type phosphor screen can obtain higher space resolution.

实验结果表明新型荧光屏具有较高的耐压性能，对提高X射线变像管的空间分辨率有重要作用，而且能延长变像管的寿命。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
