It is discussed mainly in four aspects:how to choose proper evaluative factor and establish reasonble evaluative index system;how to make the specific check items of every evaluative index;how to decide the importance and degree of each index,and how to organize and carry out the evaluation.

主要从如何选取评定因素，建立合理的指标体系；制定各考评指标内容；确定指标权重和等级标准；成绩评定的组织实施4个方面进行了论述。

Analyses show that refractive index changeinduced by thermal effect is similar to the change induced by other effects for linearabsorption,if laser pulse width is far less than the characteristic time of sample,i.e.refractive index change is directly proportional to spatial part of incident pulse laserintensity,so time averaged nonlinear refractive index can be defined.

结果表明，当激光脉冲宽度远小于被测样品的特征时间时，对于线性吸收来说，其热效应产生的折射率变化与其它效应产生的折射率变化有类似的形式，即与入射脉冲激光光强的空间部分成正比。因而可定义时间平均非线性折射率。在这种情况下，可用通常的Z-scan法进行非线性折射率及热光系数的测量，所得结论符合以前的实验结果。

At the lower generation (C5) of the autotetraploid eggplant, plant shape index and the ratio of the well-balanced plants (9.19%) are low. The average shape index for 12 strains of the three different female parents is 0.4779. But its genetic rate is: h^2=96.39%±3.52%. Plant shape index shows strong minus correlation with average fruiting ability, it's relique interrelated coefficient is: r=-0.9989 and correlative heritability is: h=-95.22%.

In general under ideal perfect competitive environment, because of the replaceability the active output of a certain generating set will fall in vast scale while its bidding price is slightly raised, and the sensitivity index based on its own price will be a very small negative value; along with the increment of market power this index will gradually increase until sensitivity index becomes zero. This conclusion can be spread to the situation of multi-generating sets.

在理想的完全竞争环境中，由于可替代性，某台发电机组稍微提高投标价格一般会导致其有功输出的大量减少，基于自身价格的灵敏度指标为很小的负值，随着机组市场力的增加，该指标逐渐趋于增大，直至为零，此结论可推广至多台机组的情形。

Since 1997, the trend of deflation has been appeared in our country , the commodity retail price index, the residents consumption price index and the production material trade price index all have been appeared to be negative growth, the increase extent of money supply and the money circulation velocity also have been appeared to decline.

1997年以来，我国出现了通货紧缩的趋势，商品零售价格指数、居民消费价格指数、生产资料批发价格指数均出现了负增长，货币供应量增幅和货币流通速度也出现了下降的趋势。

Methods Five body indices of a total of 1 757 AGA neonates converged from 12 cities in China were caculated with computer,which were the gestational maturation,the Quetelet Index,Rohrer Index,Recumbent length Croun Rump length Index,Recumbent length/Head circumference,Mid-Arm circumference/Head circumference r...

Based on systematic analysis, nine seismometry parameters that response earthquakes well in North China are selected, which are seismic frequency, seismicity scale, mf-value, b-value, D-value,η-value, seismicity intensity entropy and seismicity time entropy. Using synthetic anomaly index method, we calculated their seismic anomaly index values separately and synthesized these values into a chronogenesis curve. After studying its short-term anomaly characteristics to earthquakes, the criterion index for M≥5.8 earthquakes in North China is obtained. The R-value test indicts that it has good prediction effect.
