Objectives: Substance use and physical abuse during pregnancy are known health problems that detrimentally affect maternal health and birth outcomes; however, many health professionals pay little attention to these problems. The aims of this study were to estimate the prevalence of substance use and physical abuse during pregnancy in different ethnic groups and to explore the effects on birth weight.

目标：物质使用及受虐是公认危害母体及胎儿之危险因子，但甚少受到医疗工作人员的关注，为协助妇女保健工作之推展，本研究系以问卷资料访谈评估不同种族妇女於怀孕期间物质使用及受虐经验对婴儿出生体重之影响。

Filling of the ventricular occurs during ventricular diastole while ventricular contraction and ejection of blood occur during ventricular systole.

对心室充盈时发生心室收缩和血液过程中发生心室射血时心室收缩舒张。

We showed that Sgs1 is hyperphosphorylated during S phase and is usually under-phosphorylated in G1 stage. The Cdk1-crippling backgrounds led to diminishment of Sgs1 hyperphosphorylation during S phase.

我们发现Sgs1磷酸化的程度在S 期最多，而在G1时期则最少，在Cdk1受损时这样的磷酸化变化则会消失。

Based on the data observed in four seasons during May 2004 to February 2005 and collected during the red tide occurrence period from 2001 to 2005 in the Nanji Islands sea area, the seasonal variations in species composition, dominant species and cell abundance of phytoplankton in the sea area, their relations to the environmental factors and the occurrence conditions of dinoflagellate red tide in spring are analyzed.

根据2004年5月－2005年2月4个季节的调查资料以及2001-2005年赤潮发生时收集的资料，分析了南麂列岛海域浮游植物的种类组成、优势种类、细胞丰度的季节变化及其与环境因子的关系、春季甲藻赤潮发生状况。

To study the different permeability characteristics of rock, transient permeability tests of limestone and diorite were carried out. The permeability evolution and the relation between pore pressure and time of rock specimens during the complete stress-strain course were investigated. The strain-permeability equations of rock specimens during the deformation and failure course were set up. Finally, the penetration mechanism of two types of rocks was analyzed.

为研究岩石不同渗透特性，对石灰岩和闪长岩进行了瞬态渗透实验，研究了岩样全应力－应变过程中的渗透率演化规律以及孔隙压差与时间的关系，并建立了岩样变形破坏过程的应变－渗透率方程，最后分析了这两种不同类型岩石渗透机理。

SRG-L protein wasmainly observed in diplotene/pachytene spermatocytes, round and elongating spermatids.We can conclude this gene was activated during the early stage of meiosis, andtranscription of it kept high level during spermiogenesis.

因此初步判断这个基因在减数分裂早期被激活，转录在整个精子形成期维持较高水平的表达，有可能在精子发生后期起特殊作用，与减数分裂和精子变态成形相关。

LC filter is an important part of this hybrid reactive power dynamic compensation. The parameters of capacitor and inductive winding of LC filter change during operation with the changing surrounding temperature, the self-heating and the insulation ageing of capacitor, etc. During the installation and commissioning, there may exist errors that can deviate the actual parameters and correspondent harmonic oscillation frequency from the designed value and result in filter disarrangement.

LC滤波器是动态无功补偿装置中的重要组成部分，由于它的电容器和电感线圈参数，在运行过程中会因周围温度的变化、自身发热和电容器绝缘老化等因素影响而发生变化，在安装和调试过程中会存在误差，从而使实际参数和相应的谐振频率偏离设计值，导致滤波器失谐，这就要求对滤波器进行优化设计。

Only during those centuries in Paris when I was a penitent, one of Satan's discalced Children of the Night, during that long slumber only, did I give up my rings.

只有在巴黎，当我作为一名忏悔者，作为撒旦那赤足的黑暗之子进入漫长沉睡的世纪里，我才没有配戴我的戒指。

Some people find that their minds are more active or distractible during walking than during sitting meditation. This may be because walking is more active and the eyes are open.

有些人感觉他们的心在行禅时较坐禅更容易掉举散乱，这可能是因为行禅是动态的，而且眼睛又是睁开的缘故。

The dynamic coherence analysis based on multivariate autoregressive modeling was applied in the observation of synchronization between brain areas during cognitive processing.The result indicates that the synchronization of relative brain areas happens automatically despite the distractive stimulus during object perceiving,but the disturbed attention affects the synchronization of those areas involved in the judgement and voluntary movement as the way it affects the reaction time.

基于多变量自回归模型的动态相干性分析方法，被用于观察不同脑区在认知过程中的同步化，结果显示，人在感知和识别物体时，相关的脑区自动地发生了同步化的神经活动，这种同步化被证实是不受干扰刺激影响的，但被干扰的注意力确实影响了与判断和主动运动有关的脑区的同步化，而且这种影响的趋势与反应时间的分析结果一致。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
