Our research suggests that the cholic acids depress the growth rate of HUVEC with time-concentration dependence.

结论胆酸对HUVEC的生长率有很强的时间-浓度依赖性抑制作用，这种抑制作用除了直接损伤内皮细胞外，还可能与其抑制内皮细胞本身的分泌VEGF有关。

At the same time, young people should be encouraged to communicate with their peers and develop their interpersonal skills, which may help them greatly to reduce dependence on their parents and are essential in the maintenance of healthy mental cond ition.

The factors affect on the degree of substitution of product, yield and apparent viscosity, such as the mol rates of EPTAC with -NH2, reaction temperature, reaction time and the content of water in system have been discussed in detail. FTIR spectrometer and UV spectrometer are used to characterize the structure of the derivative and it is proved that substitution reaction mainly occurs on the -N element .The particle size and morphology of chitosan and quantemary ammonium salt of chitosan are analysised by comparing photos of their scanning electron microscope. The degree of substitution of HACC is determined by acid -base conductometric titration. An error in current formula of DS has pointed out and a correct formula has presented.On the base of experience of above experiment, the reaction conditions of HACC were systematically investigated through orthogonal design, and then the best conditions are found. Water-solubility and dependence of pH are studied.

壳聚糖和环氧丙基三甲基氯化铵在异相条件下发生反应，通过单因素实验，制备了一系列不同性能的壳聚糖季铵盐，本文首次详细讨论了反应条件(反应摩尔比、反应时间、反应温度、水含量)对产率及产物性能的影响；用红外光谱和核磁共振对结构进行表征分析时，发现季铵盐阳离子基以N位上取代为主；通过电镜图片对壳聚糖和季铵盐衍生物外观形貌进行对比，采用酸碱电导滴定法测定产物的取代度，并对常用取代度公式做了修正。

Furthermore , the occurrence of density dependence is closely associated with species abundance and the strength of conspecific aggregation at local scales .

此外，局部尺度密度制约效应的发生与物种丰富度，同种聚集强度存在紧密的关联。

Abundant species with high strength of conspecific aggregation tend to show density dependence

个体数多、同种聚集度高的物种易于受到密度制约效应的影响。

We first investigated whether habitat heterogeneity influenced tree distributions, and then examined the conspecific tree patterns and density dependence after removing the effects of habitat heterogeneity.

我们首先分析了生境异质性是否影响树木的分布，然后排除生境异质性的干扰检验同种分布格局和密度制约效应。

The school sports development\'s condition and the locality economic development level present the obvious correlational dependence.

2学校体育发展的状况和当地经济发展水平呈现出明显的正相关关系。

According to the correlational of the house price and the land price dependence, summarizes the three major problems of Taiyuan real estate development, proposed the three adjustment mentality of the real estate development.

根据房价与地价的相关关系总结出太原市房地产发展的三大问题。提出了今后房地产发展的三项调整思路。

曾经FeedBurner推出过中文版，现在如果你进入FeedBurner网站，点选上方Languages想要选择语言时，你会发现并没有中文选项，这对有些人要使用可能不方便。。。。

The polymers substituted with hexyl and octyl on phenylene also show a nematic phase, however, the nematic phase disappears for the polymer substituted with decyl. The polymers substituted with alkoxy on phenylene self-organize into a lamellar structure, and their phase behavior shows obvious dependence on the alkoxy length.

苯环上烷基、烷氧基取代的聚合物都具有纤维状的特征形貌，当烷基、烷氧基碳原子数为6时在高温都存在一个向列液晶相，当烷基碳原子数增加到10时液晶相消失，而烷氧基碳原子数增加到12时该向列液晶相仍然存在。
