It also applies kernel density estimation method to investigate the accumulative relative productivity and the dynamic evolvement of its distribution. The result shows that there exists no country level absolute convergence of the provincial productivity whether incorporating environmental factors or not. The provincial TFP index is in a divergence trend and the provincial technical efficiency index has a convergence trend when incorporates environmental factors.

objective to evaluate the value of infrared thermography in the diagnosis of injuries in such soft tissues as neck,shoulder,waist,leg,elbow and wrist.methods infrared thermograph (type wp-95) was used to do general physical check up for 221 young soldiers with a regular military training history ranging from 1 to 5 years,whose infrared thermograms were then compared with those of 100 new recruits without any military training experience.results there were abnormal thermograms on 180 (81.45%) of the 221 cases and 6 (6%) of the 100 new recruits （p.05.all of the 186 cases with abnormal thermograms were x-rayed with only 28 cases(i.e.15.05%) abnormal.there was a distinct difference between the two methods of physical check-up (p.05).conclusion infrared thermography manifests distinctive abnormal thermograms of soft tissue injuries suffered from military training,providing definite diagnostic message for clinic.to utilize infrared thermography correctly is of vital importance in ensuring the health of servicemen.

目的 探讨软组织损伤颈、肩、腰、腿、肘、腕红外热像图的诊断价值。方法应用wp-95型红外热像仪，对221例常规军事训练1～5年的年轻干部及战士进行红外热像仪的全身检查，并与刚入伍未参加训练的新兵100例进行对照。结果 221例经红外热像图检查发现颈、肩、腰、肘、腕出现异常热像图的有180例，占81.45%；而100例新战士仅有6例颈、肩、腰、肘、腕出现异常热像图，占6.00%，两者比较差异有显著性（p＜0.05）。186例异常热像图受检者全部做x线摄片检查，x线摄片异常者仅28例，占15.05%，两者检查比较差异有显著性（p.05）。结论红外热像图对军事训练所致软组织损伤有其独特的异常热像图，为临床提供明确的诊断信息，正确的使用红外热像图，对保证部队广大指战员的健康水平有着重要作用。

In the second place, this paper uses the financial data reported by China's private listed companies and statistical analysis skills to test the theories and hypotheses. The research collects all required data from 2000 to 2002, examines the profit ability, the gain ability, the repay ability, and the cost control ability for all sampling listed companies by using Paired-Samples T test in the quantitative analysis section. The results show that these listed companies'profit decreases, income increases, repay ability enhances after the companies go public. Finally the paper takes the non-operating expenses as the illustrating index for the cost control capability of the companies to demonstrate that there is an obvious increase of non-operating expenses after getting great amount of money in IPO, in this sense it can be stated that there is the intendancy of low capital utility rate in private companies.

研究选用了描述性统计分析方法对样本企业IPO前后时段的财务指标进行了对比考查，并运用配对样本t检验方法进行了显著性检验，研究结果表明民营企业在IPO前后的盈利水平总体上是显著下降的；同时研究也显示虽然获利水平出现了小幅上升，但这是由于企业通过IPO融资增加了投资规模导致的；企业的偿债能力在IPO之后有明显的好转；研究最后以营业外支出作为企业成本控制能力的解释指标，发现企业在IPO上市融得大量资金后对主营业务以外的支出有明显的增多，可以判断民营企业存在资本利用效率低下的现象。
