While great progress in developing the single postal territory have been made since the establishment of the Universal Postal Union 134 years ago, large differences in quality of service, postal reform and on the adoption of new technologies still exist between industrialized and developing nations, said Mudavadi before more than 1,500 delegates to Congress, including about 70 ministers from most of the 191 member countries of the Union.

虽然发展中国家单一邮政领土很大的进展一直以来，万国邮政联盟134年前成立了，在服务，邮政改革和质量上的巨大差异在采用新技术仍然存在着工业化国家和发展中国家表示，在1500多名代表参加大会，其中包括约70来自该联盟191个成员国大多数部长穆达瓦迪。

Though the Waddington and von Bertalanffy programs have not been confirmed in the typical accomplishments and representations in molecular biology in general, and molecular genetics in particular, there are interesting advances that fall between those searches for broad theories couched in mathematically precise differential equation form, and the narrow classes of mechanisms, usually described in qualitative multilevel causal language, that constitute the vast majority of current biomedical explainers.

Waddington 和 von Bertalanffy氏方法，尽管其贡献和代表性并没有在一般意义上得到分子生物学或者在特别意义上得到分子遗传学的确认，但还是在以下方面产生了有益的进展，即，它使我们的广泛的理论搜寻进步到精确的数学微分方程式的形式和通常以定性的多级因果语言来描述的机理的狭窄类别之间，由此构建了当代生物医学因果辨析的主体内容。

This project was conducted starting with the three interrelated subjects the structural characteristics of desertification landscapes in different bioclimatic zones, desertification driving factors and their function mechanism, and the dynamic model of landscape space for the occurrence and development of desertification in representative desertification regions and on the basis of in-depth studies of the relations between landscape structural characteristics and processes of desertification and their stability; the driving force of different time-space scales of desertification and their proportion, manifestation form, and action mechanism in the desertification processes; and the establishment of threshold conditions for the surface wind erosion and has achieved important progress in the definition of desertification conception

本课题从三个相互联系的专题（即不同生物气候区荒漠化景观的结构特征、荒漠化驱动因素及其作用机理、典型荒漠化地区荒漠化发生与发展的景观空间动力学模型）入手，在深入研究荒漠化景观结构特征与过程的关系及其稳定性，不同时空尺度的荒漠化过程驱动力及其在荒漠化过程中所占比重、表现形式及作用机制，地表风蚀临界条件的确定等内容的基础上，虽未建立荒漠化景观空间动力学模型，但在沙漠化概念，末次间冰期以来沙漠化过程时间序列和特征冷暖时期沙漠、沙地空间分布格局，现代沙漠化过程中自然因素和人文因素的作用、贡献率、沙漠化土地对气候的反馈作用以及风蚀临界值，沙粒跃移轨迹参数和能量分布，我国沙漠化防治思路和对策，沙尘暴区划和沙尘暴指数等方面取得了重要进展。

This study consisted of two sections, the one is about the relationshipe between ear and jaw, the other is about the comprehensive treatment for microtia.

在我国，近年来各地相继开展了耳廓再造手术，晚近又有同期进行中耳成形术的报道，在手术设计方面进展较大，但对小耳畸形和颌面部畸形的关系至今尚未见到有关的研究报道，对第一、二鳃弓综合症缺乏足够的认识，反映在对小耳畸形的治疗上也缺乏全面考虑。

In the article, we took part sample out of 158 patients to exam the expression level of Bcl-2 and Fas in myasthenic thymus tissue, and to find the role of which in whole pathogenesis. we also try to find the role of neopterin and sIL-2R through examing the concentration of neopterin and sIL-2R in peripheral blood of 26 MG patients. Material and methods1.select of case: to choose 158 patients who wear followed up from 1988 to 2002 after operation. All patients were diagnosed as MG, and treated with same medical cure during period of preoperation and post operation. 2.Collectionofdata:.To collect all data through designing a uniform follow-up table for thymectomized patients ,and to analysis the effect of factors including age, gender, disease duration of preoperation, clinic types and pathological types to prognosis at three follow-up period?

本文拟在对全组病例的远期预后进行流行病学统计分析的基础上，通过抽取一定量样本，研究重症肌无力患者胸腺组织中伽 12、Fas的异常表达及生发中心的形成在重症肌无力发病机制中可能的作用，以及它们对胸腺切除术后远期预后的影响；与之相似，通过检测部分样本外周血清中新碟吟和可溶性IL－2受体的浓度及其与正常对照组的差异，以期推测两者在重症肌无力起病及病情进展中的作用和意义，并分析其对胸腺切除术后远期预后的影响。

The reaction of cyclic b-keto esters with CF3CO2ZnCH2I provides the corresponding ring-expanded products with the advantage of mild condition in moderate to good yields. A simple and efficient procedure has been developed for a variety of 1,3-diketones converted into the corresponding 1,4-diketones and trans-1,2-disubstituted cyclopropanols in high yields. In conclusion, this new type of organozinc reagents has been developed for many useful reaction in organic synthesis.
