比较地

Jiangxi immigrants came to Western Hunan and Southern Hunan whose economy was backward and traffic was inconvenient, due to their seldom contacting with the outside world, suffering impact tinily so that they can, better retain this phenomenon.

With such a triumvirate, things will be easier; reorganization at lower levels, implementation of the relevant plans, and so on, will go more smoothly.

有了这样的三把手，事情就比较好办了，下面单位的调整，计划的执行等等，就可以比较顺利地进行了。

It is my belief that much unnecessary perplexity can be avoided if we limit ourselves strictly to the two units, money and labour, when we are dealing with the behaviour of the economic system as a whole; reserving the use of units of particular outputs and equipments to the occasions when we are analysing the output of individual firms or industries in isolation; and the use of vague concepts, such as the quantity of output as a whole, the quantity of capital equipment as a whole and the general level of prices, to the occasions when we are attempting some historical comparison which is within certain limits avowedly unprecise and approximate.

我相信，当我们论述整个经济体系的行为时，如果我们将自己的讨论严格限定于使用两种单位，即货币和劳动，那就可以避免很多不必要的困惑和混乱。当我们孤立地分析单个厂商或单个行业的产出时，可以在这种情形继续使用特定产出和设备的原用单位。当我们试图进行某种历史比较时，可以在这种情形使用诸如总产出数量，总资本设备量和一般价格水平之类含糊不清的概念，这是因为在一定限度内，历史的比较本来就是不精确的和粗略的。

The phylogeny and applied prospect of MES are summarized in the paper. The principle of this system is analyzed from the point of view of acoustics. The surveying and filtering technology of auxiliary parameters, sounding data and the theory of image form, backscatter strength data processing, are researched deeply in the paper. The optimal model of velocity of sound is given. For sound ray tracing, some methods of correction of sound ray curve are developed. At the same time, an ideal model of sound ray tracing is proved and given. The GPS technology is applied for the determination of tide, attitude of vessel. Moreover, some methods are given. As an important topic, the systematic error is discussed in the paper. Some filtering methods are researched in this paper. Based on the current methods of image processing, the procedure and methods are tested and given that adapt to sonar image processing.

ABSTRACT Amorphization of Cu-Zr system by mechanical alloying of elemental Cu and Zr powder mixtures (30-65at% Cu) and mechanical grinding of the alloys with Cu concentration ranging from 59 to 75at% have been extensively investigated. The structural changes, crystallization behavior as well as atomic short range ordering were followed by differential scanning calorimetry , X-ray diffractometry and nuclear magnetic resonance spectroscopy .

本文采用多种技术系统地研究了球磨Cu和Zr混合粉末制备的Cu〓Zr〓（x=30，33，40，50，55，59，65）非晶合金的形成过程和球磨金属间化合物得到的Cu〓Zr〓（x=59，65，70，75）非晶合金的形成过程，比较了它们形成过程的异同，同时研究了球磨形成的非晶合金的晶化行为以及原子短程有序结构，并与急冷非晶合金作了详细的比较。

W. Herbert, afterwards Dean of Manchester, in the fourth volume of the "Horticultural Transactions," 1822, and in his work on the "Amaryllidaceae"(1837, pp. 19, 339), declares that 'horticultural experiments have established, beyond the possibility of refutation, that botanical species are only a higher and more permanent class of varieties.

，后来曾任曼彻斯特教长，在1822年《园艺学报》第四卷和他的著作《石蒜科》（Amaryllidace一书（1937年，19，339页）中宣称，&园艺试验不可反驳地证明了植物学上的物种不过是比较高级和比较稳定的变化而已&。

As an important grain production base of North China, Hetao area can provide high-grade farm products. But there are some serious eco-geochemical problems including soil salification, which restricts regional agricultural development, and endemic diseases of arseniasis and fluorosis, which badly affect the human health.

作为我国北方重要的粮食生产基地可以为全国生产出优质的绿色产品；但河套地区也具有比较严重的生态地球化学问题，首先是土壤的盐渍化制约了河套地区农业的发展，其次是全区以砷氟中毒为主的地方病比较严重，极大地影响了该区人民的身体健康。

The subject used many research methods, such as combination of autoptical and survey data, the combination of comparative research and empirical studies. Recalling history and status of the reform of public and nonprofit hospital. After comparative study on theory and model of international typical corporate governance, we analyzed corporate governance reform, point out that the current corporate governance reform in public and nonprofit hospital exists problems as following: persons absent from their duties in hospital, the Boards right and obligation is ambiguous and confused, the management practices in hospital beyond control and supervision, lack of effective corporate governance, motivation mechanisms is not perfect.

本课题采用资料调查与实地考察相结合，比较研究和实证研究相结合等研究方法，回顾了我国公立非营利性医院改革的历史及现状，经过对国际上典型的公司治理理论和模式的比较研究，剖析国有企业法人治理结构改革的经验教训，指出了目前公立非营利性医院法人治理结构改革中还存在着医院国有资产出资者缺位、董事会权利划分缺乏细化、医院管理层行为得不到有效控制和监督、缺乏有效地法人治理、激励与约束机制不完善等问题。
