Unfortunately, it has been shownthat these methods are not suitable to study about chemical bonds due to not involvingchemical bonds. In order to consider chemical bonds obviously, we have proposed an atom-bondelectronegativity equalization model on the basis of density-functionaltheory and electronegativity equalization principle. The main contents of our atom-bond electronegativity equalization model contain:(1)Considering the fact that there are varies of chemical bonds in molecules andpartitioning the molecular electron density as summations of atomic electron densitiesand chemical bond's electron densities, we obtained the basic equations of atom-bondelectronegativity equalization model: the expression of the total energy 〓, theexpression of the atom electronegativity 〓 and the expression of the bondelectronegativity 〓.

为了明确地考虑和处理分子中存在的化学键，以便能够更好地描述体系中的电荷分布进而准确地描述分子体系中的有关物理化学性质，尤其是与化学键有关的物理化学性质，我们在密度泛函理论和电负性均衡原理基础上提出了原子-键电负性均衡模型，原子-键电负性均衡模型的主要内容是：(1)考虑到分子体系中存在各种化学键这个事实，将分子空间看成是由原子区和化学键区组成的，将分子的单电子密度表达成为分子中各组成原子的单电子密度和各化学键的单电子密度的加和，从而得到了原子-键电负性均衡模型的基本方程：分子体系总能量〓和分子中原子电负性〓和化学键电负性〓表达式。

There was no notable difference in avifaunal zoogeographical pattern of China before and after 30 years by cluster analysis. The accordance of present analysis and zoogeographical region division in Cheng(1976), Zhang(1991), and Cheng(1997)'s reflected long term stability in evolution of avifauna.

鸟类区系的动物地理分布格局聚类分析结果，在30年前后没有明显差异，和郑作新（1976），张荣祖（1991）以及郑作新等（1997）的动物地理区划结果一致，反映了鸟类区系演化的长期稳定性。

It accounts for more than 64% of species recorded in China. The study was the most comlplete , systematic work about birds in Yunnan and recorded the most species of birds in Yunnan at present. The recources status and geographical distribution of birds in Yunnan were deeply studied, and the characters and evolution tendency of avifauna in Yunan, geographical division of birds in Yunnan were discussed.

本项目通过系统的分类和区系研究工作，共描记云南鸟类848种(1074种和亚种)，占中国记录鸟类种数的64％以上，是目前记录云南鸟类物种最多、最全面和最系统的工作；并在深入研究云南鸟类资源状况和地理分布的基础上，探讨了云南鸟类的区系特征及其演化趋势、三级地理区划。

Main streets of area buildings to the "beauty" for back-alley street "new clothes" and promote City "beauty project"-- this is the Lo Wu District since last March as our civilization District, the continuation of civilization in the district to a new level activities measure.

对辖区主要街道建筑物再"美容"，让背街陋巷换"新衣"，全面推进城区"美容工程"―――这是罗湖区自去年3月成为我市文明区之后，今年继续开展文明区再上新台阶活动的举措之一。

A third backcourt area extends from the service line to the base line.

第三个是后区，是由发球区线延伸到底线之间的区域。

We found that it is the effect of odd-order term of f which describe the total energy collocation between forward wave and backward wave that causes the difference of modulation instability between normal dispersion region and abnormal dispersion region.

第三，根据增益谱的比较，我们从色散关系式中看到了产生这种变化的原因。正是由于存在f奇次项的影响而导致了这种在正常色散区和反常色散区变化趋势的不同。

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。

Beijing Real Estate and Construction Bar Association Professional Committee of Liu Hua, deputy director of the Law Society: The contract agreement in the area, it seems to me there are at least two flaws: First, it agreed to construction area for the sale area, construction area is passed and the pool area and the area, and in this contract on the pool area also lacks transparency, developers will not tell you specific assessments where the location of the area, the specific area is the number, which for him provided an opportunity for fraud; Secondly, the contract agreed by the parties, permit the forecast area of 3% error, if the pool size increases as long as no more than 3%, you can only increase the pool for this increase the size back the principal.

北京地产及建造界律师协会专业委员会刘华副主任律师公会：合同协议，在该地区，在我看来至少有两个缺陷：第一，它同意建筑面积的销售区，建筑面积是通过和游泳池区和地区，并在此合同的游泳池也缺乏透明度，开发商不会告诉你具体评估那里的位置，面积，具体领域是的数目，这为他提供了一个机会，欺诈；其次，该合同约定，允许预测面积的3 ％的错误，如果池大小的增加，只要不超过3％，你只能增加池的大小增加本金。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
