Finally, calculate the response of the ionization chamber with the equivalent electron source theory.

在等效电子源理论计算中，先通过解析的方法得到等效电子源，然后用蒙特卡罗技术计算等效电子源在电离室内的能量沉积，将蒙特卡罗技术和等效电子源理论结合起来。

To overcome the shortcomings of present divisible e-cash scheme, for the first time, the thesis introduces group signature into divisible e-cash system and view the e-cash withdrawn by users as the group certificate issued by group administrator. As all of ancestor nodes of the payment node arc blindly transformed, the divided parts from one e-cash are no longer linkable.

针对现有可分电子现金方案存在的诸多缺陷，本文首次将适合于大群的群签名思想引人到可分电子现金中，将用户提取电子现金视为群管理员颁发给用户的群证书，通过将支付节点前的祖先节点进行盲化使得同一电子现金分割后的不同分割单元间不再有可链接性。

The camera length of electron diffraction in transmisson electron microscopy is one of the main technical parameters in designing electron microscope and the electron diffraction analysis to microcrystal sample.

透射式电子显微镜(Transm isson E lectron M icroscopy，TEM)中的电子衍射相机长度，是电子显微镜设计和对微晶体样品进行电子衍射分析的主要技术参数之一。

Mitochondria was relatively little in size. Round primary lysosome with high electron-densed granules and secondary lysosome with high or low electron-densed granules were seen frequently. DCs contained many rough endoplasmic reticulum, the Golgi apparatus and ribosomes. The vacuoles with flocculent electron-densed granules were rare. Some special granules in cytoplasm were seen, whose surface like earphone were covered with a membrane. High electron-densed contents in the granules were near one side and the other side was bright. The nucleus became markedly small in volume, nephroid or hoofed in shape. The nucleus had little euchromatin and lots of heterochromatin under nuclear membrane.

子宫内膜癌组织DC超微结构特征如下：细胞形态不规则，与正常子宫内膜组织DC相比，胞膜较光滑，胞膜表面树突状胞浆突起显著减少，部分突起呈粗短状；胞质中线粒体相对少，圆形而电子密度高的初级溶酶体和不规则形且电子密度高低不一的次级溶酶体多见；高尔基体、粗面内质网、核糖体丰富；含微量絮状电子致密物的胞饮小泡显著减少；胞质中可见形态特殊的颗粒，该颗粒外周膜包裹，略呈圆形，中间部位稍弯曲，如耳机状，颗粒中由高电子致密物居于一侧，而另一侧则呈透亮状；胞核显著减小，居于胞质一侧，常呈肾形或马蹄形，核内常染色质较少，异染色质多边集于核膜下。

We described that the nitro group is a stronger electron withdrawing and meta activating characters than the imide group, the amino and hydroxy are both electron donating groups and had ortho, para activating characters. The methyl group might have a steric hindrance effect in this reaction. Our results indicated that methyl group at the ortho position of the amino group on the benzene ring, the steric hindrance effect became stronger.

另一方面，由产率上的结果来看，可以得知硝基为强力的拉电子基团，会减少邻位和对位胺基的电子密度比间位多；而氢氧基与胺基是供电子基团，会增加邻位和对位胺基的电子密度比间位多；甲基取代对反应则只有立体障碍的影响，而且与反应的氨基成邻位存在下影响最大。

The four fluorescence peaks are generated separately by the combined actions of the methyl parathion and the acetone. In methyl parathion molecule, there are the transition of n electrons in nitryl, the transition of π electronic structure formed by the oxygen atom and the benzene ring and the transition of n electrons in P=O group. In acetone molecule, there is the transition of n electrons in C=O group.

分析得到，四处荧光峰分别是溶剂丙酮分子中C=O上的n电子跃迁、硝基上的n电子跃迁、甲基对硫磷分子中氧原子与苯环形成的大共轭π电子结构跃迁以及P=S上的n电子跃迁共同作用产生。

Because of the nondirectional property of ionic bond and the fully delocalized property of pi electrons on carbon layers, translation will not change the electronic structure of carbon layers, resulting in that A-GIC and AE-GIC hare quite good lubrication as well. The electrons come from metals mainly transfer to the delocalized pi orbitals of carbon layers, and the increase of delocalized electrons will make metal graphite intercalation compound more electro-conductive than graphite itself. Because ionic bond between metals and carbon layers is weaker and its lattice energy is much less than that of typical NaCl crystal, so metals could be left from interlayers. The Mulliken populations of C-C in intercalation compounds are smaller than that of graphite, and the HOMO energy level of GIC is higher than that of graphite too. These Lead to that GIC will easier be oxidized.

由于离子键没有方向性，又由于碳层中的π电子是充分离域的，所以碳层不会由于平移而改变其电子结构，金属石墨层间化合物仍具有很好的润滑性；金属失去的电子主要转移到碳层的离域π轨道中，碳层离域电子增多使金属石墨层间化合物的导电性比石墨增强；金属与碳层间的离子键强度比较弱，其晶格能远小于典型的离子晶体，因而金属易从石墨层中脱出；金属石墨层间化合物中的C-C间Mulliken布居值小于石墨中C-C间的值，且金属石墨层间化合物的HOMO能级也高于石墨的HOMO能级，所以石墨层间化合物中的碳原子较石墨更易被氧化。

Theoretical predict is given, that electron density of inner shell at nuclear surface decreases and energy level also decreases with increasing of charge state, nuclear lifetime increases slightly with previous reason but increases with a jump when energy level drops to a critical value.

理论预言了随着电荷态的增加，内壳的电子在核表面的电子密度降低，内壳电子能级也降低，不稳定原子核的寿命由于前一原因而缓慢增加，但当内壳电子能级降到特殊能量时产生剧烈增加。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
