Four sheep lines, HU-Yang, Chinese M erino monotocous, Chinese Merino multiparous for wool production and Chinese Merino multiparous for mutton production, were used in this study. Litter sizes were recorded for each ewe in the four lines. Primers for BMP15 and BMPR-IB gene were designed from database sheep sequence and polymorphisms were detected by PCR-RFLP method.

Results There was no noticeable changes in nasality and total NAR for type Ⅰ patients at stage one, but further study showed that simple maxillary sinusitis had effects on nasality while frontal sinusitis and sphenoid sinusitis failed to.

结果 Ⅰ型1期患者术后1月鼻音和总鼻阻力与术前无明显变化；进一步研究发现，单侧上领窦炎对鼻音有一定影响，手术后1月及3月基本恢复正常；单侧额窦炎或蝶窦炎对鼻音无明显影响。

The clinical characteristics of renal involvement in H and C groups consisted of 2 cases (50%) and 12 cases (43%)of simple hematuria, 1 case (25%) and 14 cases (50%) of hematuria plus proteinuria, 2 cases (7.27%) of hematuria plus nephrosis, respectively.

低分子肝素钠治疗组中紫癜性肾炎单表为单纯型血尿3例，血尿+蛋白尿1例；对照组单纯血尿12例(43%)，血尿+蛋白尿14例(50%)，血尿+肾病2例(7.2%)。

Aeromonas hydrophila BA6 was identified as a nonpathogenic agent,while the other seven strains (BA1,BA3,BA10,BAH,BA15,BA16 and XA23) were pathogenic. However,there would be difference in virulence among the strains of the same or different species.

结果表明嗜水气单胞菌BA6株为非致病株，其余7株嗜温气单胞菌为致病株，但细菌的毒力大小在不同表型种间和不同菌株间都存在差异。

There was significant difference among monoterpene volatiles released from healthy, weevil damaged trunks of Pissodes punctatus and their branches. Walking P. punctatus in maturation feeding and sexually matured stages displayed different olfactory responses toward monoterpenes in a Y-tube olfactometer.

通过GC-MS分析，发现健康的与遭受华山松木蠹象Pissodes punctatus Langor et Zhang危害的华山松Pinus armandii Franch树干以及华山松枝梢释放的挥发性单萜烯在含量上存在较大差别；利用Y-型双向选择嗅觉仪进行的室内趋向反应实验发现，处于补充营养期和交尾产卵期的华山松木蠹象对单萜烯表现出不同的趋向反应。

In the project of micro pedrail mobile robot, monocular vision can not satisfy the requirement of visual navigation and monocular vision s visual field is obviously smaller than binocular vision.

在微小型履带式移动机器人项目中，单目视觉不能满足机器人的视觉导航需要，并且单目视觉机器人的视野范围明显小于双目视觉机器人的视野。

It is in Japan and Taiwan separated from the plane on the basis of the Division I researchers developed a new type of fiber separator, the first in the domestic production of single-effect separator manufacturers, patent number: 200730017298.8 one outlining the type XRDF-Ⅱ Single-efficiency separator for separation of waste paper in the light and heavy debris and water from the pulper slurry broken for the second solution.

该机是在日本和台湾分离机的基础上由我司科研人员开发出来的一种新型纤维分离机，在国内第一家生产单效分离机的厂家，专利号：200730017298.8一、概述 XRDF-Ⅱ型单效分离机主要用于分离废纸浆中的轻重杂物，并对来自水力碎浆机的浆料进行二次碎解。

We study the phase-separation and microstructure of the pure binary and trinary mixed LB and LS films of Dimyristoyl phosphatidyicholine cholesteroland sphingomylin deposited from pure water subphase by π-A isotherms and tapping mode Atomic Force Microscopy.

在本章中我们用这种极易溶于水的阳离子型聚合物PEI为一软垫，研究以此软垫为基底的不同生物分子和它们不同种二元及三元混合单分子膜体系在含PEI亚相上的相结构情况，初步的讨论了它们以云母为基底的IS膜和LB膜的微结构或者说是该软垫对单分子膜微结构的影响。

Nowadays the researches of frequency distribution of data are almost limited to normal distribution, while other distributions are seldom studied. Many frequency distributions of data are not normal. This kinds of frequency distribution of data widely exist. Unimodal frequency distribution of data often occurs.

现在绝大多数关于频数资料分布的研究都是基于正态分布的，而对其他类型的分布研究得比较少，实际上频数分布在许多情况下并非呈现正态分布，分布的形态丰富多彩，很多资料都是呈现单峰分布，本研究就是利用数学上常见的八种连续型变量的分布类型去拟合单峰频数资料。

To eliminate common-mode voltage of cascaded multi-level inverter, three kinds of phase-difference SVM based on left and right bridge vectors are proposed firstly. From these three modulations, equivalent SPWM components are deduced, and the unipolarity and bipolarity of output waveforms are analyzed. 2π/3 PD-SVM (phase-difference space vector modulation) is testified be unipolar.

为消除级联型多电平逆变器的输出共模电压，首先提出了基于左、右桥臂矢量的三类相差空间矢量调制(space vector modulation，SVM)技术，数学推导出三类调制技术的等效正弦脉宽调制(sine pulse width modulation，SPWM)的调制波，并分析了其各自相电压输出波形的单、双极性，证明2π/3相差SVM必为单极性调制。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
