量出

Arrange a keyword: Had wanted before making a station your site popularizes what keyword, retrieve on the net after the keyword that had better think up you to want to do below, must not retrieve a quantity certainly big, popular keyword is occasionally bad to do, be inferior to be like a hand from a few minor term, for instance I stand this Tianjin website construction is a popular keyword, do very hard, I had avoided he, the keyword that I push above all is Tianjin webpage design, tianjin webpage is made, so easy search is recorded some.

整理要害词：在做站之前要想好你站点推广什么要害词，最好想出你要做的要害词后在网上检索下，不一定非要检索量大，有时候热门的要害词不好做，倒不如从一些小词如手，比如我这个站"天津网站建设"就是个热门要害词，非常难做，我就避过他，我首先推的要害词是天津网页设计，天津网页制作，这样轻易搜录些。

This method undertakes comparative getting the area between the spare parts to equation of geometry of the face in model of CAD of different spare parts above all - surface contact relation and type, use amount coming back theory general face - the face expresses to be helix; relative to instantaneous motion next, the helix that goes up to many surface contact undertakes making operation,; of helix of the motion when making the opposite very short time between the spare parts is final, according to the spare parts abut concern plan and abut spare parts move relatively helix, undertook an analysis to assembling instantaneous of whole of the spare parts in the model to concern with drive movably, give out not between the method of calculation of helix of opposite instantaneous motion between photograph adjacent spare parts and them but the judgement method of drive sex.

该方法首先对不同零件CAD模型中面几何方程进行比较得到零件之间的面-面接触关系和类型，并应用旋量理论将面-面相对瞬时运动表示为螺旋；然后，对多个面接触上的螺旋进行交运算，生成零件之间的相对瞬时运动螺旋；最后，根据零件邻接关系图和邻接零件相对运动螺旋，对装配模型中零件整体瞬时可动性和驱动关系进行了分析，给出不相邻零件之间的相对瞬时运动螺旋计算方法和它们之间可驱动性的判定方法。

RESULTS There were no complications relating to ECC in all of the 240 infants.The ECC time ranged from 49 min to 184 min and the aorta cross-clamp time ranged from 17 min to 110 min.The ultrafiltration volume ranged from 150 ml to 400 ml. The intraoperative Hct ranged from 16% to 20% and the hematocrit after MUF ranged from 30% to 39%.The mechanical ventilation support time after operation ranged from 6 h to 72 h.

结果 240例患儿未发现同ECC有关的并发症，ECC时间为49～184 min、升主动脉阻断时间17～110 min，改良超滤滤出液体150～400 ml，全组患者术中Hct维持0.16～0.20，改良超滤结束Hct为0.30～0.39，术后呼吸机辅助时间6～72 h，24 h胸腔引流量30～110ml，术后输入库血量100～200 ml。

Based on the repeated tests, the optimum structure of muffler were defined and the influence of inside pipe structure variation of the muffler on muffling effect were studied.

在大量试验的基础上，研究了二级扩张室式消声器中穿孔管结构的变化对消声器消声效果的影响，并优选出最佳结构的消声器，该消声器消声量大且功率损失小，能满足对内燃机日益严格的噪声要求

During December 1st 2006 to May 30th 2007, data collection was conducted by the semi-structural in-depth interviews and questionnaires of Pittsburg Sleep Quality Index, social support scale and Parental Stress Index to repeatedly measure 14 primipara and multipara in three time periods: the first week after the birth, the first week after the infant is transferred out, and the first week after they go home.

於2006年12月1日至2007年5月30日期间，分别在早产儿出生一周、转出加护病房一周以及返家后一周，以匹兹堡睡眠品质量表、社会支持量表、亲职压力量表，重复追踪14位初经产妇并进行半结构式深度访谈，以更深入了解早产儿母亲之睡眠品质及其影响因素，研究对象有效答覆率为93.33％。

In this paper, we mainly discuss some preliminary studies about statistical diagnostics for one kind of restricted multivariate linear regression model. At first, we give the parameters estimation of this model. After that, the problem of outlier test is considered by giving the equivalence relations of estimators and statistics in multivariate case deletion model and mean shift outlier model under the restricted condition.

本文主要讨论的是一种带线性约束的多元线性回归模型（这里的多元是指多个因变量对多个自变量的情形），重点在与统计诊断方面的一些初步研究，首先给出带有线性约束的多元线性回归模型的参数估计，其次讨论了该模型的异常点检验问题，主要介绍了常见的数据删除模型及均值漂移模型，并证明了此两种模型统计量之间的等价性。
