The paper fristly compared the fertile soil with the incinerated sterile soil on the number of micro-algae , soil pH value , soil organic matter soil available phosphorus and soil nitrogen.And then, the author put fertile soil, which included micro-algae, proportionally into sterile samples and cultivated them respectively under illumination condition (micro-algae can live and reproduce)and dark condition(micro-algae will die in some time).The above indices were measured in 0, 30, 60 and 90days respectively, The analyse of the interrelation between the change of micro-algae"s number and the changes of soil pH value, soil organic matter, soil available phosphorus and soil nitrogen indicated:Soil micro-algae which were native to fertile soil conld adapt to the changed circumstance and light acted as a decisive role to the distribution of soil micro-algae.Under dark condition,the micro-algae"s number declined gradually and went to zero in the end,while under illumination condition ,on the 90th day, the micro-algaes number of per gramme was 6-7 times more than that of the beginning.

本文首先对肥沃土壤与经高温焚烧后的贫瘠土壤中的微藻数量、土壤pH值、有机质含量、有效磷含量和全氮量进行比较研究，然后将包含微藻的绿化苗圃地肥土按不同比例接种进入贫瘠土样中，分别在光照条件和黑暗条件下进行培养，在0天、30天、60天和90天分别检测以上指标，比较有光条件和无光条件下，即有藻条件和无藻条件下贫瘠土样所发生的变化，并分别对微藻数量的变化与土壤pH值、有机质含量、有效磷含量和全氮量的变化之间做相关性分析，以评估肥沃土壤中的微藻接种进入贫瘠土壤后的生长情况以及对贫瘠土壤的改良作用。

Finally, the author proves the sharp bound for the indices of convergence of n*n reducible Boolean matrices with f〓≥2 the writer lets f〓 be the greatest common divisor of the distinct lengths of the elementary cycles of the associated digraph D (A for a reducible Boolean matrix A , and characterizes the matrices with the largest index.

最后，设f〓为可约布尔矩阵A的伴随有向图D的所有圈长的最大公约数，当f〓≥2时，我们得到了可约布尔矩阵幂敛指数的一个上界和达到最大幂敛指数的矩阵的完全刻划。

By analyzing these indices, combined with their flight behaviors at the airport and its neighbourhood, we identified bird species that have the potential to threaten flight security at Baita Airport; The results showed that the 23 bird species including magpie and red falcon are the most hazard to flight security and the eight bird species including sparrow Hawk and Greenfinch are the hazard.

其结果表明：构成飞行安全威胁有两类：喜鹊和红华等23种鸟类为最危险的鸟类，雀鹰和金翅雀等8种鸟类为较危险的鸟类。

The results of the study show that the Japanese men judoka have the features such as gregariousness,courage,frankness,self—confidence;While the top judoka reveal the dis- tinquished difference from the ordinary judoka in the six facors—gregarousness,agitation, courage,strain strain and so on.has also been pointed out that all these psychological indices could be ...

研究结果表明，日本男子柔道运动员在乐群、敢为、直率、自信等7个因素上趋于高分特征；优秀柔道运动员则在乐群、兴奋、敢为、紧张等6个因素上，与普通柔道选手相比存在显著性差异。这些心理学指标，可作为选择和培养优秀柔道运动员的理论及测试依据。

A numerical method to estimate hemolysis level in blood pump was presented and hemolysis indices were calculated.

给出了一种利用数值方法计算溶血指标的方法，并通过溶血指标的计算评价了血泵内的溶血程度，发现雷诺切应力是导致溶血的主要原因。

Methods Before treatment, the first hemospasia and BPRS evaluation were taken, and indices of blood rheology measured using XNs Electron Auto Whole Blood Viscosity Red Cell Electrophoresis Apparatus (researched and produced by Shanghai Medical University) in the 32 schizophrenics.

经氯丙嗪治疗2周后，重复上述实验及第2次BPRS评定。统计学处理采用t检验。结果32例精神分裂症病人治疗前血液流变学指标较正常人有明显异常，经氯丙嗪治疗后，全血高切变、全血低切变、红血球压积和红血球电泳时间有显著下降，同时BPRS评分也下降，其差异均有显著意义（P＜0.05）。

However,the number of the LmPRM is very poor in the actual applications.The reasons of baffling their wide application have many aspects, hereinto includes:since the variety of mechanism type,difficult to select an optimal mechanism solution for a operation task;the performance indices depend on their topological limb types,the actuated layouts,and design parameters, such that their design is a difficult task.

然而实际在用的并联机器人机构的数目却非常少，阻碍其广泛应用的原因有很多，其中包括：机构类型的多样性，难以选择适合于操作任务的最佳机构方案；机构的性能指标依赖于其拓扑类型、驱动布局和设计参数，难以设计。
