纲后，丝网品栽较众，产物参不差不齐，但有一点务必不合明，丝网的纲数与丝径不决着丝网的开孔率和网布薄度，同时，又感化着感平乳剂的网上驻留度，较着，开孔率不小、丝线不细的丝网可涂布的感平乳剂不离薄，所以曝平工夫也答相答加长，反之则曝平工夫缩长。

The exposure dose from various nuclide through eachpathway to the population surrounding the nuclear power plant whichwas assumed to be in an accident was calculated by statistic calculationmethod using practical meteorological data.The relationship betweenradioactive release and exposure dose was obtaine,dwhich is independentof the accidential process and the meteorological condition.

本文借助于核电站假想事故条件下的放射性释放量，按不同的核素组，分组计算了其经各种照射途径对周围居民造成的剂量；并考虑了气象资料的统计数据，使得因天气条件两低估剂量的可能不超过5%；从而得到了与事故过程和天气条件无关的释放量和照射剂量间的关系。

Results There was a downtrend in weight of dams on GD20 as the DBTD exposure dose increased. The weight of dam's utero significantly decreased in 30 mg/kg group. A significant decrease in fetal weights was observed in all DBTD groups, and fetal sizes in 20, 30 mg/kg groups. Exposure to DBTD from GD 12-19 resulted in a distinct increase in normalized anogenital distances in female fetuses, but no effects were seen in male ones.

结果 妊娠20d时，孕鼠体重随DBTD剂量升高呈下降趋势，但与对照组比较，差异无统计学意义，30mg/kg组孕鼠子宫重量显著降低；所有DBTD染毒组雄性、雌性胎鼠体重均显著降低，20、30m/kg组胎鼠体长显著降低；所有DBTB染毒组雌性胎鼠肛门距生殖器的标化距离显著增长，而雄性胎鼠无显著变化。

The effects of doping concentration of iodine, doping time, doping temperature and exposure time on volume resistivity of anthracite were studied; and also the effects of solution concentration of cupric chloride, doping time, doping temperature, soking time of cupric chloride and exposure time on the volume resistivity were studied; Anthracitic resistivity has been decreased in dissimilar extent, and furthermore ,volume resistivity stability of the doping anthracite made by liquid phase doping method is more better than gas phase mothed; Resistivity and its stability were better than the doping method of iodine in fused salt doping method of cupric chloride.

研究了I_2掺杂浓度、掺杂时间、掺杂温度和暴空时间对无烟煤电阻率的影响；探讨了CuCl_2溶液的浓度、掺杂时间、掺杂温度和CuCl_2溶液浸泡放置时间以及暴空时间对无烟煤电阻率的影响：结果发现：I_2气相掺杂和液相掺杂均使无烟煤的电阻率有不同程度的降低，而液相掺杂法所得材料的电阻率稳定性更高；CuCl_2熔盐掺杂法所得材料的电阻率及其稳定性均优于I_2掺杂法。

At 4th week, the percentages of Clara cells over bronchiolar epithelial cells were similar between groups. At 24th week, the percentages of Clara cells were reduced in mice exposed to TCDD, NNK, CSC, or TCDD+CSC exposure, but not in mice exposed to TCDD+1 mg NNK. Thus, these findings suggested that TCDD, NNK, CSC, or TCDD+CSC exposure injuried Clara cells to lose CCSP protein in mice lung.

在A/J mice 4周实验组中，TCDD或NNK各实验组Clara cell的数目(26.6%-34.3%)与控制组(34.2%)比较，并没有明显的差异；反观A/J mice 24周实验组中，除了TCDD+NNK (1 mg)实验组外，其他各实验组Clara cell的数目与控制组(55.9%)比较明显下降11.7%-41.4%，显示暴露NNK、TCDD、CSC或TCDD+CSC皆会伤害Clara cell，暗示Clara cell对这些环境毒物比其他呼吸道上皮细胞敏感。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
