In this paper, after taking over coupling effect between electronic spin and orbital angular momentum, to revise the formula of electronic angular momentum in Bohr's theory, and electronic speed formula is obtained in a single-electron system, and to correct the energy level formula of atomic orbit in Schr? dinger's method by relativistic effect, the theoretical improving formula is built for spectrum fine splitting calculation, the calculated values are in good agreement with experimental ones, and reflect changing law of spectrum fine splitting values.

本文在考虑了电子的自旋角动量与轨道角动量的耦合作用后，通过对Bohr理论中的电子运动角动量的修改，推导出单电子体系的电子速度公式，结合对Schrdinger的原子轨道能级表达式相对论效应修正，从而得出本文的氢及类氢离子光谱精细结构值的理论计算公式，应用此改进公式，所得的计算值与实验观测值符合得很好，计算结果也反映了氢及类氢离子光谱精细结构数据变化的规律性。

Through the method of experts'investigation, to analyze the risk on this project and choose out the headstream of the risk 2. Through the method of classification, to disassemble this project 3. Through the method of simulation, to estimate the risk of investment 4. To provide the scheme to avoid and manage the risk All of these efforts made us realizing the features of this project and mastering the rule of risk. So we can complete the project within 1000 days, and create the miracle in the field of the construction on track traffic, with the features of the limited manager, the short term, the low cost, the high technology, the high quality and the perfect safety. It has been the successful nonesuch on the research of risk management art.

High above it all like the racket24 of raucous25 angels, were the joyful screams of the roller coaster riders as the cars rose and dove down the tracks next to the breakers. It was in Rockaway's "Irishtown" in all its noisy glory, seventy years ago, where Irish-Americans forgot about the Depression for a day or two, and my mother first met my father, Daniel Patrick Cassidy, and fell in love.

而高高在上压过这一切的，是乘坐过山车的人们发出的欢快的尖叫声，飞车随着轨道时而骤升，时而速降，轨道旁浪花飞溅，人们的叫声此起彼伏，就像一群喧闹天使的吵闹和嬉戏声。70年前，正是在洛克威海滩的这个"爱尔兰城"里，在这一切喧嚣、繁华之中，在爱尔兰裔美国人暂时忘掉大萧条、偷得一两天闲暇的地方，母亲遇到了父亲丹尼尔·帕特里克·卡西迪，两人相爱了。

At that time the weather visibility was not high, is having the drizzle, in fact, enlightened plum Tela to say, the train already broke down "star of in the European" to that which collapsed the railroad bridge very is also far, suddenly transmits exceptionally "sharply checks 车声", because got on the brakes extremely anxiously, in left "star of the European" the very far place all to be possible to see on the spark and the track rain water which the track burst out the mist which got on the brakes scalding hot evaporates.

当时天气能见度不高，下着微雨，事实上，迪梅特拉说，在"欧洲之星"列车离那座已经垮塌的铁路桥还很远的时候，就忽然传来异常"尖利的刹车声"，由于刹车非常急，在离"欧洲之星"很远的地方都可以看见轨道迸发的火花和轨道上的雨水被刹车的灼热所蒸发出的雾气。

Kinds of Schiff base derivatives of 2-N-benzylidene Furanmethanamine have been designed. The Net Charges of main atoms, bond lengths, bond angles, dihedral angles, IR have been calculated by means of HyperChem6. 0 program. 36 kinds of Schiff base derivatives of benzylidene adenine have been designed. Also the net charges of main atoms, bond lengths, bond angles, dihedral angles, IR, the energy gap △E between HOMO and LUMO and the nonlinear second-order polarizability β have been calculated by means of HyperChem6. 0 program. The calculated results indicated that the nonlinear second-order polarizability β were up in accordance with the △E down.

设计了腺嘌呤缩苯甲醛36种衍生物，计算了这些分子的气相几何，腺嘌呤缩苯甲醛中各原子的电荷分布，最高占有轨道HOMO和最低未占有轨道LUMO的能量以及它们之间的能量差△E，同时还计算了这些分子的二阶非线性极化率β，我们发现腺嘌呤缩苯甲醛的二阶非线性光学系数与△E有近似一致的变化关系，随着△E的减小，二阶非线性光学系数有增大的趋势。

A new method for ab initio energy partition is being developed in order to gain new insight into the nature of electron delocalization, and it is able to provide any molecule with a fragment MO basis set in which the π and σ systems have been separated out no matter whether molecule is planar or nonplanar as well as whether the π system is conjugated or cumulated.

我们的方法可以为任何一个共轭分子(无论是平面的还是非平面的，是含共轭双键的还是含累积双键的)，提供一个π与σ体系彻底分离的片断分子轨道基组。这个轨道基组不仅满足分子特殊的对称性，而且还具有确切的电子占据数。
