Abstract］ objective to evaluate the distinctive clinical value of magnetic resonance urographymru）in the diagnosis of primary ureteral carcinoma.methods to compare the accuracy of diagnosis of mru with ultrasonography,urography,retrograde ureteropyelography and ct,diagnostic imaging and progress of ureteral carcinoma were analyzed in twenty-four cases from 2000 to 2006,twenty cases had mru examinations.the original preoperative diagnostic reports of various imaging facilities were analyzed on account of the results of operation and pathology.results mru could clearly show the obstructive location of ureter.with regard to the ureteral carcinoma,accuracy of the location diagnosis was 100%.mru was superior to ulstrasonography,kub+ivp,ureteropyelography and ct we used to apply.conclusion comparing with other diagnostic imaging facilities,it has an important value in highly efficient,accurate location,safe,noninvasive and so on with mru,which can be used to show the features of primary ureteral carcinoma and has a wider scope of clinical application.

目的 探讨磁共振水成像技术在原发性输尿管肿瘤中的临床诊断价值。方法分析2000～2006年24例原发性输尿管肿瘤的影像学诊断结果，并基于术中所见和病理报告，将磁共振水成像技术20例）与超声24例）、泌尿系造影24例）、逆行造影15例）、ct(19例）的确诊率相比较。结果 mru能清晰显示输尿管的梗阻部位，定位诊断准确率为100%，梗阻病因确诊率高于b超、泌尿系造影、逆行造影和ct检查。结论与其他影像诊断方法相比较，磁共振水成像在显示原发性输尿管肿瘤特征方面具有效率高、定位准确和安全无创等重要价值，而且有更广泛的临床应用范围。

The excising quota system for distributing water resources has its innate defects and disadvantages. In order to minimize and finally to eliminate the imbalance between supply and demand of water resources, the thesis argues that it is necessary to establish water rights marketing in China, and to achieve the unity of justice and efficiency in administration ,therefore, we ought to bring new ideas to the administrative systems concerning water resources.

为提高水资源的利用效率，实现水资源的可持续利用，实现以流域为单位的整体性开发与保护，在水资源配置过程中引入市场机制，建立与完善水权市场己势在必行，这必然也对水权市场的管理提出更高的要求。

In the present study, two soybean genotypes (BZ10 and BL2) differing in root architecture and phosphorus efficiency were intercropped with a maize cultivar (Huatian 1) in a field experiment to assess the effects of soybean root architecture on nitrogen and phosphorus nutrition of the intercrops.

在温室的根箱试验中发现，浅根型、磷高效率的大豆品种巴西10号根系在土壤有效磷相对较高的表层分布较多，其表层的根系数量和长度均显著地高于深根型、磷低效率品种本地2号。同时巴西10号的根系与玉米根系接触较多。

The common power can only be used in the common fields ,but because of its inborn characteristics of forcing and outstretching, the private right often is overlooked and damaged . and the most effective approach to limit the political power is the rule of law.Bureaucratism : exorbitant administrative cost and too low administrative efficiency.

公共权力只能运作于公共的领域，但因其具有先天的强制和扩张的禀性，所以私人权利常被其觊觎和损害，而对政治权力扩张最有效的途径就是法治官僚主义：过高的行政成本和过低的行政效率。

A testing triangulation experiment for a polygon with 100 inside islets was done with this algorithm, and the result showed that this algorithm is efficient and robust for triangulating complex polygons with large numbers of inside islets. This algorithm has been successfully applied to the three- dimensional ore-body modeling and visualization system, in which it is used to triangulate the sectional polygons with inside islets, e.g., the inside stones or holes in ore-body, and its high efficiency has been proved.

因此，开征社会保障税的呼声越来越高，但要设计出既体现公平性又兼顾效率性的社会保障税，则有必要对其特点及其经济效应进行充分的认识。2社会保障税的特点社会保障税的特点，主要体现在对收

Because metal naphthalocyanine has larger conjugate system than MPc does, and its main absorption peaks shift to 750～850nm region, which is optimal for light penetrating tissue. That would endow MNc with strong photodynamic effect and weak phototoxic by-effect. And it would be a new and practical PDT photosensitizer.

本文考虑到比金属酞菁具有更大共轭体系的金属萘酞菁配合物（Metal Naphthalocyanines，简称MNc）其电子吸收光谱Q带主吸收峰比金属酞菁红移100—150nm，达到750—850nm范围，位于人体最佳透射波段的近红外区，这既可使之具有较高的激发效率和较强的肿瘤细胞杀伤效应，又可更进一步降低可见光引起的光毒副作用，可望成为新一类有应用前景的抗癌光敏剂。
