The author found that the chromone ring could be cleaved at high temperature in PPA, and the change of the ratio of ring-opened product versus the target one with the change of reaction time and temperature was investigated in details.

我们采用了两条不同的合成路线合成了第Ⅳ类化合物，对部分反应条件进行了优化，在研究过程中发现了色酮化合物在高温下的开环反应及多聚磷酸的水解作用，并对前者进行了详细研究了，获得了不同反应温度和时间下未开环产物和开环产物的比例，得到了制备相应的未开环产物和开环产物的最佳反应条件。

Thus the chemical composition of intermediate A is that of nickel nitrate tetrahydrate, that of intermediate B is of nickel nitrate dihydrate, that of intermediate C is of the monohydrate whilst that of D is anhydrous nickel nitrate.

因此，中间产物A的化学成分是四水硝酸镍，中间产物B的化学成分是二水硝酸镍，中间产物C的化学成分是一水化物，而中间产物D的化学成分是无水硝酸镍。

From the point view of product distribution, conversion of dimethyl ether and energy consumption, with RCD plasma DME conversion was higher and was hardly affected by the residence time of dimethyl ether, and hydrogen, carbon monoxide and unsaturated hydrocarbons with RCD plasma were more than those with DBD plasma.There was no liquid product with RCD plasma, but the liquid product obtained with DBD plasma consisted of aldehydes, alcohols and methoxy-containing organic compounds, for instance, formaldehyde, methyl alcohol, dimethoxy ethane and so on.Moreover, most compositions of liquid product were methoxy-containing compounds, and the liquid product selectivity was as high as 32.23%.However, energy consumption for the reaction with DBD plasma was more than that with RCD plasma.

从产物分布、转化率及能耗上看，利用RCD所获得的二甲醚的转化率高，几乎不受二甲醚停留时间的影响，且氢气、一氧化碳和不饱和烃的含量大，几乎没有液相产物，而利用DBD能获得较多的液相产物，包括一些醇、醛和含有甲氧基的有机化合物，如甲醛、甲醇和二甲氧基乙烷，且大部分组成都是含有甲氧基的化合物，液相产物的选择性高达32.23％，但是能耗较大。

Depending upon the catalyst (AlCl3, H3PO4) and the reaction conditions, either the monosubstituted product (2) or the disubstituted

乙醯化的主产物究竟是单取代产物(2)，就是双取代产物(3)，这取决于催化剂(AlCl3，H3PO4)和一些反应条件，给出特定的反应条件，学生将会确定主产物究竟是橙色的乙醯二茂铁(2)呢还是红色的1，1-二乙醯二茂铁3

乙醯化的主产物究竟是单取代产物(2)，就是双取代产物(3)，这取决於催化剂(AlCl3，H3PO4)和一些反应条件，给出特定的反应条件，学生将会确定主产物究竟是橙色的乙醯二茂铁(2)呢还是红色的1，1-二乙醯二茂铁3

In this case, the solidification of the liquid phase formed at the hipping temperature led to the formation of crystalline intergranular phases at all temperatures: however, the chemical compositions of the intergranular phases formed in the specimens with and without carbon additions were different, since for high carbon contents the resulting intergranular phase was observed to be richer in Yttrium(85% at Y/15% at Si).

在这种情况下，加压温度下液态产物的凝固在所有温度范围下都将生成间粒晶体：但是，是否添加了碳则将会使产物晶体的化学成分发生不同，因为在高碳含量下，产物晶体会更富含钇(85%Y比15%Si)另一方面，我们必须强调的时，如果Al2O3作为第三方物质加入反应混合物粉末中，那么产物晶体的结晶度将被破坏。

The result shows that the greater positive influence is from the dissolutions of carotene and browning reaction,next come the cembratriendid compounds and hypoglycemia compounds,while the negative influence is from indoles,toluene and some aldehydes,and the negative influence from...

结果表明，对评吸结果影响较大的是胡萝卜素降解产物类和棕色化反应产物类；类西柏烷类和苯丙氨酸类中性致香物质的贡献较小；负面影响较大的成分主要集中在吲哚、甲苯及一些醛类上，类胡萝卜素降解产物类和棕色化反应产物类中的个别成分也有一定的负面影响。

The analysis of X-ray diffraction and scanning electron microscope energy dispersion spectra show that the primary hydrolysis products of antimony pentachloride and its hydrochloric acid solution are amorphous antimony oxide rather than SbO2Cl.

X射线衍射和扫描电镜能谱分析表明：五氯化锑及其盐酸溶液的初始水解产物不是SbO2Cl，而是一种非晶态锑氧化合物；随着水解母液酸度的降低，五氯化锑溶液水解产物陈化五天后的晶型由非晶态向晶态变化；五氯化锑溶液水解产物经无水乙醇洗涤后水解产物仍为非晶态，而经蒸馏水洗涤虽主要为非晶态，但有少部分结晶的Sb2O5·4H2O晶体存在。

The molecular structure was clarified by IR, which revealed the existence of ether bonds. The content of tartaric acid and unreacted maleic acid were detected by spectrophotometer. The effect of some factors on the yield of ESA and scale inhibition efficiency of PESA was investigated.

利用红外光谱表征了该产物结构，表明分子链中含有醚键；利用紫外－可见分光光度法测得体系内副产物酒石酸和未反应的马来酸的含量，并系统地研究了各因素对中间产物环氧琥珀酸钠的产率和最终产物聚环氧琥珀酸钠阻垢性能的影响。

The results showed that PPC was a thermotropic liquid crystal and displayed the cholesteric banded texture. The reaction conditions had the distinct effects on the propoxy content and liquid crystal property of PPC, with the reaction temperature and content of propionyl chloride increased, the degree of substitution of propoxy increased at the beginning, then trended to steady. The transition temperature and range of liquid crystalline phase were changed with the DS of propoxy, as the DS of propoxy increased, the melt point decreased, and the liquid crystalline phase transition temperature range of PPC get wider.

结果表明，产物PPC具有明显的热致液晶性能，且呈现出胆甾型液晶的彩色条纹织构；反应条件对产物丙酰基含量和液晶性能有显著影响，随反应温度提高和丙酰氯用量增加，产物丙酰基的取代度先增大，后趋于稳定；其相转变温度和温域随丙酰基取代度改变而相应变化，随丙酰基的取代度增大，产物的熔点降低，液晶温度范围变宽。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
