The anti-jamming ability of igniter depends on the charge in the igniter. The combustion of the igniter charged with barium nitrate and those charged with magnesium powder and PTFE is stable, while the igniter charged with zirconium hydride and lead oxide is unstable. The standard error of duration of the third kind of igniter flame is 523 ms ,and also its nozzle hole is blocked seriously.

不同药剂的点火具抗干扰性能不同，其中以硝酸钡为药剂主成分的点火具和以镁粉＋PTFE为药剂主成分的点火具燃烧性能稳定，以氢化锆、二氧化铅为药剂主成分的点火具工作稳定性较差，火焰持续时间标准差为523 ms，点火具喷孔堵塞严重。

The major components in extracts of larval frass and egg masses of O.furnacalis were fatty acids.In contrast,the major chemicals in extract from larval frass of O.nubilalis were a blend of FAs and fatty acid methyl esters,and those from egg masses of O.nubilalis were FAMEs.

取食人工饲料后，亚洲玉米螟幼虫粪便和卵块提取液中的主要成分为脂肪酸；欧洲玉米螟幼虫粪便提取液中主要成分为脂肪酸和脂肪酸甲酯的混合物，卵块提取液中主要成分为脂肪酸甲酯。

Based on the data of aerosol chemical compositions obtained at WMO GAW (World Meteorological Organization Global Atmospheric Watch) station in eastern China－Lin'An regional background air pollution monitoring station, two methods (referred as Malm method and Stelson method) that were described by Malm (Malm et al.,1994) and Stelson (Stelson and Seinfeld, 1981) were used to study the mass closure of sampled aerosols.

本文通过在WMO GAW 区域大气本底污染监测站－临安大气本底污染监测站采集的气溶胶样品的化学成分的分析结果，分别用Malm（1994）和Stelson（1981）提出的方法（分别记为Malm方法和Stelson方法）重建气溶胶质量浓度，并与称重获得的质量浓度进行对比，发现虽然Stelson和Malm方法所考虑的物质组成及所使用的化学成分个数并不相同，其计算结果略有差异，但总的来说两种方法都能较好的反映绝大部分的气溶胶质量，在实际应用中可以根据所分析的化学成分数据情况和研究的目的采用不同的质量重建方法。

This may lead to a change of certain gene components, which is prerequisite for an incisive reorganization of the gene

这又会引起某些基因成分的改变，基因成分的改变是基因成分彻底改组的前提。

It implies that the calculation of movements of mobile cells is not accurate enough, that must affects the mass exchange between the mobile cells and immobile cells. Furthermore, because the value of concentration be calculated is always at center of an element and the finite difference grid is fixed, which may gives rise to numerical dispersion, especially when the steps of space are injudiciously selected.

另一方面，颗粒的位置直接影响到其所含各种成分的质量变化，这将在一定程度上影响最终各种成分的浓度计算精度，而且，该算法最终统计各种成分的浓度时，所用的窗口也是已有的固定的有限差分网格，当网格选择不合适时，有可能产生人工数值弥散。

Nutrient components of sweet potatoes with weed management in organic cultivation was better by intercropped soybean. Crude protein, reducing sugar and starch were better with thrice intertillage. Nutrient components of sweet potatoes with different mulch was better by peanut shell.

不同方式控制杂草对甘薯营养成分之影响试验中，四种不同绿肥间植，以绿肥大豆在各成分中表现较佳；四种耕犁次数控制杂草试验，三次耕犁对粗蛋白、还原醣及淀粉有较佳之表现；四种敷盖物以花生壳对各种成分有较佳之表现。

The results showed that there's clear negative correlation between the chemical components such as protein, total nitrogen and nicotine etc., and the sensory quality such as quality and concentration of aroma, offensive taste, irritancy, after taste and so on, but these chemical components and the sensory quality such as physiological strength an...

然而 ，烟叶化学成分是相当复杂的，目前在烟叶中已鉴定出的化学成分已超过 30 0 0种，因此，要直接分析烟叶化学成分与烟叶质量的关系是困难的。目前主要采用的方法是数理
