Especially now the need to abate pollution is very important,so the request of letting is more and more strict.Many developed countries use feul ejecting technique and leting microtechnique to satisfy the request.

特别是目前对环境污染治理的要求不断提高，发动机的排放法规要求越来越严格，许多发达国家采用了电控燃油喷射技术和电控排放微处理技术来满足法规要求。

Objectives: We attempt to determine if obstructive sleep apnea leads to higher incidence of positive microvolt T-wave alternan; thus higher risk for arrhythmic death; and correlate MTWA result with severity of OSA as measured by apnea hypopnea index.

目的：我们研究阻塞性睡眠呼吸暂停综合症是否导致阳性微伏级T波电交替发生率增加从而使得致死性心律失常发生的风险增加；由呼吸暂停低通气指数确定的严重睡眠呼吸暂停综合征是否与微伏级T波电交替相关。

The authors research the algorithm for power system static voltage stability. Taking the modulus minimum eigenvalue of power flow Jacobian matrix as the criteria to weigh the weakness of power system, the active power injected into nodes equivalent is substituted by equivalent conductance to ground as well as the reactive power injected into nodes is substituted by equivalent susceptance to ground.

研究了电力系统静态电压稳定性算法，以潮流雅可比矩阵最小模特征值的大小作为衡量电网薄弱程度的标准，以等效对地电导代替节点注入有功功率，以等效对地电纳来代替节点注入无功功率。

The two molecules of the permanent electric dipole moment and induced electric dipole moment of the interaction, called induced force.

这两个分子间的永久电偶极矩和诱导电偶极矩的相互作用，称为诱导力。

The results indicate that the effect of anhydrous and un-hydroxyl resin is better than liquid paraffin and each of electrocast zirconia and monocline zirconia can promote sintering of magnesia-calcia brick,and the effect of monocline zirconia is better than that of electracast zirconia.

结果表明：作结合剂用时无水无羟基树脂效果好于液体石蜡；作为添加剂时电熔氧化锆和单斜氧化锆均能显著促进镁钙砖的烧结，其中单斜氧化锆的效果好于电熔氧化锆。

The exciting effect of motherwort herb on the uterine smooth muscle may have something to do with the alteration of the ion concentration in relation to myoelectric activity, resulting in the increase of myoelectric activity of pacesetter cells as well as in the acceleration of depolarization of spike activity.

益母草对子宫的兴奋作用可能是通过改变了与电活动有关的一些离子浓度，使起步细胞电活动加强及动作电位去极化速度加快所致。

The mudsill and bracket of RWD/QX--48 X1X 2 electrical dust precipitator act as the primary study subject in this paper, and finite element analysis and optimization analysis are made by use of large-scale finite element analysis software I-DEAS, aiming at the demerit of nonstandard design on electrical dust precipitator in our country.

中文摘要：本论文主要以RWD/QX—48×1×2型电除尘器的底梁和支架为研究对象，针对我国电除尘器生产单位对其设计不规范、结构不合理的缺点，利用大型通用有限元分析软件I-DEAS对其进行了有限元分析和优化计算。
