Results: The PCNA mean labelling index was 48.84％± 13.63％, and the apoptotic labelling index was12.26‰± 5.20‰. The Kaplan-Meier survival curves showed that the postoperative survival time of the patient was shorter when the tumor infiltrated to the adventitia of esophagus,with lymph node metastasis, without keratinization, PI ≥ 40％ or AI＜10‰. Using forward multivariate Cox regression analysis, only the parameters of pN category and PI could be verified as independent prognostic factors.

结果：36例手术切除的食管鳞癌组织平均PCNA表达指数(PCNAlabellingindex，PI)为48.84％±13.63％，细胞凋亡指数(apoptosisindex，AI)为12.26‰±5.20‰；PI升高与患者年龄小、分化程度低、有淋巴结转移和肿瘤进行性浸润呈正相关，而AI升高与分化程度高、角化明显呈正相关；绘制Kaplan－Meier生存曲线，发现病变侵及食管外膜、有淋巴结转移、无角化、PI≥40％或AI＜10‰的患者术后生存率明显降低；COX比例风险模型分析，发现只有淋巴结转移和PI是影响预后的独立因素。

Take Chongqing for example,the relation between each compositive index and load is analyzed,and the relation curve of power load and compositive index in observation year is also drawn.

The results of this study indicate that: 1 the post–surcharge secant secondary compression index decrease with the increase in surcharge ratio; 2 the amended post-surcharge secant secondary compression index also decrease with the increase in surcharge ratio; 3 time at which secondary compression reappears increases with the increase in surcharge ratio; 4 the post-surcharge secondary compression strain rate under the same final load with surcharging and without surcharging have a linear logarithm to logarithm relationship.

根据研究的结果显示：1超载比愈大，后超载割线二次压缩指数所受到的折减愈大，表示对软弱粘土的二次压缩沉陷量改良效果愈好；2修正之后超载割线二次压缩指数亦随超载比的增加而折减；3二次压缩再现时间与超载比的关系显示，增加超载比会延迟二次压缩再现的时间并可将分析结果以一均值曲线表示； 4对后超载应变速率分析发现在相同最终载重，未受超载作用与受超载作用的二次压缩应变速率呈现一双对数的线性关系。

On the one-week postoperative radiographs, the mean Cobb angle was 15.4 degrees, the mean curve correction was 73.4%, and the mean fulcrum bending correction index was 122.1%.

在术后一周的X片中，平均Cobb角为15.4 °，平均曲线修正指数为73.4％，平均支点弯曲校正指数为122.1％。

Based on the mechanism of nitrogen transfer among different rice leaves, red edge slope and red edge position of the most upper and the 3rd expanded leaves were investigated specially. And using the two red edge parameters (red edge slope and red edge position), a new vegetation index (red edge curve shoulder angle vegetation index, abbreviation RSAVI) was calculated to detect rice nitrogen nutrition status.

基于氮素在水稻不同功能叶片之间运转规律的机理，文章重点分析了第一和第三完全展开叶红边斜率和红边位置的变化，并基于红边位置和红边斜率构建了一个新的植被指数（命名为&红边曲线肩夹角植被指数&，简称为RSAVI）监测水稻氮素营养状况。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
