American stocks represented 66% of the world's market value in 1970 and have been declining bumpily since then, primarily as a result of the growth in emerging markets, according to Russell Investments, which uses Russell and Morgan Stanley Capital International, or MSCI, indexes in its analysis.

广告据Russell Investments根据罗素指数和摩根士丹利资本国际指数所作的统计显示，1970年时，美国股票在全球总市值中占66%，但随着新兴市场的发展，这个比例持续下滑。

These results indicate that sperm washing by centrifugate in morphology analyses has impact on SDI and TZI.

精子形态学分析中离心精液对精子畸形指数和畸形精子指数有影响。

Methods Semen analyses were carried out according to the World Health Organization manual for 47 subfertile men,film preparation before and after centrifugate washing,then use HE dyeing,and assess the deformity ratio of sperm headbodytail and SDITZI.

47例人精液标本进行常规检测密度及活力后，分别在离心前后涂片，应用快速苏木素-伊红染色法进行染色，检测精子头部、体部、尾部畸形率。对比精子畸形指数和畸形精子指数是否受到离心洗涤的影响。

Myzus persicae were prevail in plantation of Chaenomeles spciosa, occurrence degree had no relative with altitude , but had direct ratio with the number of summer

桃蚜在资丘木瓜种植区普遍发生，发生程度与海拔高度无明显相关性，但与木瓜树的夏梢多少成正比；研究有蚜株率和蚜情指数与木瓜产量的相关性表明：当蚜情指数达0.3以上时，木瓜产量降低60％以上；采取及时剪去嫩梢或喷洒1％洗衣粉40kg／666.7m~2等无害化治理措施能有效的防治蚜害。

Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.

仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量；(2)可分出4种基本的群落类型：马尾松林、柏木林、栓皮栎林和马尾松＋栓皮栎林，各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异；(3)污染胁迫下，物种在群落中的生态优势度发生了变化，反映了群落中不同物种相互替代的过程，这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考；(4)对群落中王要物种更新的调查发现：栓皮栎林对污染不敏感；柏木林污染区与对照区幼苗数量及分布格局均有明显差异，污染条件下群落未来演替受到严重干扰。

The results show that the value of burning rate pressure exponent of propellant and its change law can bring about a great change of interior ballistic behavior, The new type high-energy propellant whose burning rate pressure exponent is decrescent as pressure increasing can obtain higher interior ballistic piezometric efficiency, and reduce the sensitivity of bore pressure and muzzle velocity on loaded conditions of propellant.

结果表明，发射药燃速压力指数的大小及其随压力的变化规律对内弹道性能有很大的影响，对于燃速压力指数随压力升高而减小的新型高能发射药，可获得较高的内弹道示压效率，降低膛压和弹丸初速对发射药装填条件的敏感性。

The diversity index of soil dematiaceous hyphomycetes was the highest but the evenness was lower in town-oasis, whereas in desert and gobi the diversity index was obviously lower, and the species evenness was higher.

在小镇-绿洲生境中，土壤暗色丝孢菌的Shannon-Wiener多样性指数最高，均匀度较低；而在沙漠和戈壁生境中多样性指数明显较低，而物种的均匀度较高。
