The results showed that LRK could significantly inhibit the mammary hyperplasia caused by estrin, reduce the content of serum 〓, raise P level, promote the production of DA in hypothalamus and mammary tissue, decrease the release of 5-HT, inhibit the secretion of serum PRL, reduce the sensitivity of mammary tissue to estrin and progestogen, prevent the expression of mammary tissue on PCNA, the effect was equal to triphenylamine oxide, obviously superior to the control group of Ru Zeng Ning.

通过实验研究，建立了具有肾虚肝郁证侯群的乳腺增生病理模型，利用免疫组化技术、图像分析系统、荧光分光光度法、放射免疫法等现代医学研究方法，从病理形态学、医用体视学、神经内分泌学、阴道细胞学等方面，观察了利乳康口服液对模型动物整体状态、乳腺组织病理形态、血清激素、神经递质以及卵巢功能的影响，结果表明利乳康口服液能明显抑制雌激素引起的乳腺组织增生，降低血清E〓含量，升高P水平，促进下丘脑及乳腺组织中DA的产生，减少5-HT释放，抑制血清PRL分泌，降低乳腺组织对雌、孕激素的敏感性，阻止乳腺组织PCNA的表达，其效应与三苯氧胺相当，明显优于乳增宁对照组；另外，利乳康口服液还能缓解模型动物肾虚肝郁证侯群，增加其体重，调节其整体状况，改善模型动物不规则动情周期，减轻其子宫及卵巢的病变，抑制子宫内膜的过度增长，调节卵巢功能，揭示了中药利乳康口服液对神经内分泌和卵巢功能的整体调控作用，以及对本病发生、发展的预防作用

Biodiversity is one of the front areas of current biological research. The mechanisms of the formation, spatial distribution pattern, conservation and utilization of biodiversity have been an important area of biological and environmental research. In this study, through analyses of data about plant diversity, animal diversity, geographic factors, climatic factors, and energy factors by use of GIS software, statistic software and ecology software, the mainland of China was divided into 241 small districts of 2° by 2°. The environmental factors in each district were analyzed and isopleth maps of environmental elements were depicted.

生物多样性是当今生物学研究的热点问题之一，生物多样性的形成机制和分布格局以及保护利用问题一直是生物学和环境科学所研究的重要内容，本文由此出发，以中国陆地为研究区域，通过植物多样性数据、动物多样性数据、地理因子、气候因子、能量因子等资料，利用MAPGIS、MAPINFO等GIS软件，SPSS、DPS等统计学软件以及CANOCO等生态学软件，将中国陆地划分为241个小区，分析了各区内的环境特点，统计了各区内生物多样性的数量，并绘出环境因子等值线图，中国陆地种子植物科、属、种，裸子植物种、蕨类植物种、兽类、鸟类、爬行类、两栖类种数的等值线分布图，对中国陆地植物、动物多样性现状、分布格局及与环境因子的关系进行了研究。

The relations between the growth of Noctiluca scintillans, Prorocentrum sigmoides Bohm ,zooplankton and physical,chemical factors of seawater were studied in this paper.

研究大鹏湾夜光藻、反曲原甲藻、浮游动物种群增殖与浮游动物和海水理化因子之间的关系，采用的方法是根据它们的种群增殖态势与浮游动物和理化因子的比较，依据空间理论的数学基础，按照规范性、偶对称性、整体性和接近性这四条原则，确定参考数列（母序列：夜光藻和反曲原甲藻、浮游动物）和若干比较数列（子序列：浮游动物和海水理化因子）之间的关联度。

Founded in 1963, the International Research Group on Ostracoda is an interdisciplinary, international organization of about 400 research scientists studying living and fossil Ostracoda.

介形类动物国际研究组成立于1963年，是跨学科的国际性组织，它拥有约400多位从事活的介形类动物和介形类动物化石研究的科学家。

We compared three competing hypotheses which maintained that euprimates originated in Africa, the India subcontinent, or East Asia. Combined the recent achievements on the mammalian fauna exchanges during early Eocene between Europe and Africa, Europe and Asia, and Asia and India subcontinent, the paleogeographic models of around Turgai Strait, the new dating results of the collision between Indian subcontinent and Asia, and the phylogenetic analysis of euprimate, we suggested that the Asian-origin hypothesis of euprimates are more reliable.

全面对比了真灵长类动物亚洲起源说、非洲起源说和印度次大陆起源说，结合前人有关欧洲与非洲之间、欧洲与亚洲之间、亚洲与印度次大陆之间早始新世时的动物群交流的研究，以及有关图尔盖海峡古地理、印度板块与欧亚板块碰撞时间的研究成果，在真灵长类动物分支系统分析的基础上，提出真灵长类动物亚洲起源说是目前获得支持证据最多的假说。

Since its establishment in 1936 as the nation's first wildlife experiment station, the Patuxent Wildlife Research Center has been a leading international research institute for wildlife and applied environmental research, for transmitting research findings to those responsible for managing our nation's natural resources, and for providing technical assistance in implementing research findings so as to improve natural resource management.

Patuxent野生动植物研究中心始建于1936年，是美国第一个野生动物实验站，目前，该中心已成为国际一流的研究机构，主要从事野生动物和应用环境研究，促进研究成果的转让和应用，更好的管理自然资源。

The studies of relationship between zoobenthos and environmental factors were conducted in this paper,and how to protect and utilize zoobenthos has been suggested. zoobenthos ; environment factors ; effect ; protect and utilize

底栖动物的生长繁殖、种类组成和现存量在不同水体和区域间存在着明显的差异，环境因子对底栖动物的影响相当复杂，不仅因子众多，而且各个因子对底栖动物中不同类群的作用并不完全一致，因此对这方面进行研究具有重要的意义，以下从理化因子和生物因子对底栖动物影响来加以概述。1理化因子对底栖动物的影响1.1水质对

The second part is a generalization about developing of the animal law. Laboratory animal law. A new trend of legislating on this issue is put forward in the third part ,. The last part do some primary studies on the newly emending wild animal law.

第二部分对动物法的发展做了归纳，第三部分在对实验动物的情况和实验动物法做了介绍与初步研究，最后对野生动物保护法的修订这个中国动物法的重要方面做了初步的探索。

When we used those two multivariate statistic analytical techniques to study the spatio-temporal variation laws of benthic community structure at Shenzhen Bay, the results indicated that: 1 There was not obverse difference in intertidal benthic community structure between Futian, Shenzhen and MaPi, HongKong in Shenzhen Bay in Spring, 2000. However, there was continual gradient change in community structure from outer bay to inner bay. 2 There was obvious deference with the respect of benthic community structure between station C and stations Al, A2, A3 in transect A and station B in transect CBA in Shenzhen Bay. There being no benthos at station C in Summary, 2000, it indicated that station C had been polluted very heavily. 3 Deferent seasons and deferent tide sites are the most two important factors which play influence on benthic community structure at stations Al, A2, A3 and B3 in Shenzhen Bay.

用这两种多变量方法研究深圳湾底栖动物群落结构时空差异，结果表明(1)2000年春季深圳湾底栖动物群落结构组成在深圳福田一侧与香港米埔一侧并没有明显的差异，而是沿湾外向湾内呈现连续的梯度变化；(2)在深圳福田一侧的C断面的底栖动物群落结构与A、B断面有明显的差别，2000年夏季在C断面没有采到任何底栖动物，表明C断面已经遭受了严重的污染；(3)季节和潮区是影响深圳湾A1、A2、A3、B3站位底栖动物群落结构组成时空差异的两个最重要的因素。

However, enamel and enameloid are significantly different in development, and dentin shows many histological variations; hence their evolution has been intensively studied. Nevertheless, their genetic basis has been revealed only in tetrapods.

这两类动物的釉质和釉质瘤发育是截然不同的，牙本质发育在组织学上差异也较大，关于这两类动物进化方面的研究很多，但涉及遗传基础的研究仅限于四脚动物。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
