In order to solve the problem,We proposed a simple formula for computing paraxial travel time of single-way wave operator. The formula is based on the forward and inverse transform between time-space domain to frequency-wavenumber domain and from vector field to exponential manifold. The travel time are expressed as polynomials of the horizontal offset between the two points, and the single-square-root operator in frequency-wavenumber domain are expressed as polynomials of wavenumber. Coefficients of travel time polynomials and that of single-square-root operator are related each other and calculated by Lie algebraic integrand, exponential map and the saddle-point method.

Secondly, the correlation between talent people resource index and economic index is studied and the regression model in which talent people resource index is as independent variable is established. In the end, some suggestions and countermeasures on the development of talent people resource in Shannxi province are presented.

通过建立的陕西省人才资源指数体系和经济发展指标体系，分析研究体系中各指标的相关性，建立以人才资源指数为自变量的经济发展与人才资源的数学关系模型，定量分析研究了陕西人才资源对经济发展的影响；提出了陕西省人才资源开发的规划和对策。

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。

The feeding and excretion of three little fishes (Hemiculter. leucisculus, Tilapia. aurea and Cirrhinus. molitorelld) was studied and their effect on water quality of Qiankeng reservoir in Shenzhen City Around the topdown effect of fish was also studied. Based on the analysis of their stomach contents, their diet composition was assayed. The three fishes" feeding rhythm in cage and their rate of digestion indoor were looked into, and their daily ration was estimated through the method of daily average fullness index. Using the spectrophotometer, the content of chlorophyll a in the stomach was measured, and the feasibility of taking the chlorophyll a as an index of measuring the feeding of fish on phytoplankton was studied. Adopting the national standard method, the effect of the three fishes" excretion on total nitrogen, total phosphorus, CODMn, pH, turbidity and conductivity coefficient was surveyed. The effect of feeding and excretion offish on water quality was discussed and the results revealed as follows:H.
