The fire retardancy and smoke suppression of soft PVC were tested.The results showed that:(1)the mechanical property of coupling agent-treated fire retardant was improved since the interfacial combination between the fire retardant and matrix was enhanced;(2)the using amount of molybdenum trioxide had no significant influences on...

结果表明：经偶联剂处理过的阻燃剂，由于增强了其与基体的界面结合力，从而使其力学性能得到提高；三氧化钼的用量对聚合物的阻燃效果影响不明显，而随着硼酸锌和三氧化二锑用量的增加，其阻燃效果越来越好。

Total electron energy and dipole moment of water molecular calculated are consistent with experiment quite well.

计算多粒子体系的电偶极矩时，根据最强化学键原理可采用有节面的精确类氢原子轨道为基函数，而不用径向光滑化的STO和GTO，因此不需作自洽计算。

A new spectrophotometric method for the determination of chromium has been developed. In HCl medium, the chromium oxidizes hydroxylammonium chloride to form nitrite, which produces a pink azo dye when reacting with p-aminobenzene sulfonic acid and α-naphthylamine.

基于铬在稀盐酸介质中氧化盐酸羟胺产生亚硝酸根，而亚硝酸根与对氨基苯磺酸重氮化后可与α-萘胺偶联产生粉红色偶氮染料，提出了分光光度法测定铬的新方法。

In HCl medium, iodate oxidizes hydroxylammonium chloride to form nitrite, which can produce a red azo dye with the reaction of p nitroaniline and α naphthylamine.

基于碘酸根在稀盐酸介质中氧化盐酸羟胺产生亚硝酸根，而亚硝酸根和对硝基苯胺重氮化后可以与α-萘胺偶联产生红色偶氮染料，提出了分光光度法测定碘的新方法。

In any case,as is well known,people resisted eating this New World food at first because its membership in the Nightshade family made it suspect,but it is now eaten throughout the worldwhile Aztec civilization is memorialized by ruins.

不管如何样，就像偶们知道的，由于它属于茄科使它受到怀疑，人们起初拒绝吃它，当然现在全世界的人们都在吃西红柿，而阿兹特克文明都只存在于废墟之中了tomato[tE5mB：tEu， tE5meitEu]n。

The results show the dispersive curve of one-dimensional photonic crystals have the normal dispersion in the transmitted bands and abnormal dispersion in the band gaps which is similar with that of elastic electronic dipolar.

结果表明一维光子晶体的色散曲线与弹性电偶极子的经典色散曲线类似，在光子晶体的导带为正常色散，而在禁带呈现反常色散。

And the judgement of sex of function odd even is Chongzhongzhi is weighed undoubtedly, the appears easily error solving a problem when the article plans to solve this kind of problem through be opposite undertakes classify is analysed, with period help classmates clarify understanding further, deepen understanding, promote master.

而函数奇偶性的判定无疑又是重中之重，本文拟通过对解决这类新问题时轻易出现的解题误区进行归类剖析，以期帮助同学们进一步澄清熟悉，加深理解，促进把握。

Theycan travel at tens or possibly even hundreds of kilometers per second,and in the case of young stars extend over a parsec in length.

它们的速度可从10km/s直到数百km/s，而来自年轻恒星的偶极外向流能延伸到1秒差距外。

Set up of pooling capital from Wenzhou Xinbo Chemical Industry Co., Ltd and American Arbor International Trade Stock Co., Ltd, Xinya Meticulous Chemical Industry Co., Ltd of Wenzhou of Sino America joint-ventures is a professional chemical enterprise specialzing in organic pigment of matenitrogwn series.

中美合资温州鑫雅精细化工有限公司是近年脱颖而出的专业生产偶氮系列有机颜料的化工企业，于1997年由原温州市鑫博化工有限公司与美国雅博国际贸易股份有限公司(AARBOR INTERNATIONAL CORPORATION)合资组建而成。

Since β values are obtained by a power series expansion of electronicenergy or dipole moment in AM1-FF scheme, it does not provide us the insightinto the electronic origin of excited states to NLO responses.

由于在AM1-FF方案中，β是由能量或偶极矩对场强的级数展开而得到的，因此AM1-FF方法无法解释β的起源，以及激发态对β的贡献。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
