比例性

The results showed that when the proportion of the resistant subpopulation within the h-VRSA was low, te level of the toxic factor and its pathogenicity to animals had no difference from that of the standard strain. If proportion of the resistant subpopulation increased the level of coagulase and lecithinase changing from positive from negative and the ring of hemolysis disappeared. The speed of proliferation of the organisms in the animal slowed down and the LD50 increased.

结果 当试验菌株中耐药亚群的比例较少时，其毒力因子及动物致病性检测结果与金葡菌标准菌株无显著差异；随着试验菌株中耐药亚群的比例增加，表现为血浆凝固酶、卵磷脂酶由阳性转为阴性，血琼脂平板上溶血环消失，细菌在动物体内增殖速度减慢，对动物的半数致死量(LD50)增加。

We herein report two cases of goats with sexual deformity.They had two systems of reproductive organs and the karyotype analysis showed mosaicism for their sex chromosomes,i.e.,60,XX / XY.The proportion of XX cell line was 42% and 54%,while XY cell line was 58% and 46%,respectively,in the two abnormal goats.

本文报道2例两性畸形的山羊，它们均具雌雄两套生殖器官，染色体组型分析显示它们均为性染色体嵌合体，核型为60，XX/XY，两头畸形山羊的XX细胞系的比例分别为42%和54%，XY细胞系的比例分别为58%和46%。

Firstly,we discuss whether the proportion of null hypothesis could be estimated, and we give the condition of the identification of the proportion of null hypothesis.

首先，我们对原假设比例的可估性进行讨论，给出了原假设比例可估的条件。

There are three principles of content : proper principles, principles and the need to narrow the principle of proportionality.

The results show that the major contribution to DOS of Mg and Pb are the 2p orbit of Mg and the 5d orbit of Pb, followed by the 3s orbit of Mg and the 6p orbit of Pb, the 6s orbit of Pb is the smallest one. There are a large number of charges around Mg, it has the characteristics of typical metal bond. Mg and Pb share some charges to form covalent bond, but the distortion of the charge at the junction is little; the proportion of covalent bond is less than the metal bond, Mg2Pb is semimetal. The elastic modulus and shear modulus of Mg2Pb are 68.6 and 27.9 GPa, respectively. Based on Pugh empirical criterions and Poisson's ratio, Mg2Pb is brittle in nature.

结果表明：Mg和Pb对态密度的贡献主要是Mg的2p轨道和Pb的5d轨道，其次为Mg的3s轨道和Pb的6p轨道，Pb的6s轨道贡献最小；在Mg原子周围有大量的电荷存在，呈典型的金属键特征，Mg、Pb之间存在共用的电荷，有较强的离域性，以共价键形式存在，但交界电荷的畸变不大，故共价键所占比例较少，金属键所占比例较大，Mg2Pb化合物呈半金属性；Mg2Pb的弹性模量和切变模量分别为68.6和27.9 GPa，Pugh经验判据和泊松比均表明Mg2Pb具有脆性。

Great majority Special Farmers" Cooperation set up by relying on the ability person , group leader business enterprise, or farming technology section, forming the property structure with differences, Hebei province is also the same, with the performance of the higher store capitalization concentration degree, appearing the difference between the big shareholder society member and small shareholder society member, the core society member and non-nuclear heart society member, the investor society member and manufacturer"s society member. the existence of advantage stock is the actual controller in co-operative societies, the surplus of the co-operative societies incline toward advantage shareholder, the Share Capital dividends is comparison far from the sum return according to trade return, Ministry of Finance funds nation the public finance prop up a funds and bring of the income is also basic for the big shareholder of the school store income.

合作社产权结构的同质性是合作社实现成员民主管理、资本报酬有限、盈余按惠顾额返还的基础，而河北省农村现阶段经济社会条件是资本和具有企业家素质的人才相对于劳动是稀缺的生产要素，绝大多数农民专业合作社都是依托能人大户、龙头企业、或农技部门组建，形成了农民专业合作社异质性的产权结构，表现为合作社股金集中度普遍较高，社员中出现大股东社员和小股东社员，核心社员和非核心社员，投资者社员和生产者社员的差别，合作社中的优势股为农民专业合作社的实际控制者，农民专业合作社的利益分配自然倾向于优势股东，按股分红的比例远高于按交易额返还的比例，国家财政扶植资金及带来的收益也基本为合作社的大股东所得。

Reverse-phase chromatography was employed for chiral separation of tropine acid enantiomers on the cellulose tribenzoate chiral stationary phases coated on a small-particle spherical silica support in an eluant system consisting of a mixture of alcohol and water.

摘 要：以乙醇-水流动相，用纤维素-三作为手性固定相对外消旋体托品酸进行了高效液相色谱手性分离考察了不同比例的乙醇-水流动相、不同流速以及用不同醇类酯化对托品酸酯在手性色谱柱上的色谱行为。
