When this flag has been specified, whitespace within the RE string is ignored, except when the whitespace is in a character class or preceded by an unescaped backslash; this lets you organize and indent the RE more clearly.

当该标志被指定时，在 RE 字符串中的空白符被忽略，除非该空白符在字符类中或在反斜杠之后；这可以让你更清晰地组织和缩进 RE。

Firstly, need some geometric information which include the vanishing line of the ground plane, a vanishing point for the vertical direction and a known vertical height.

该方法首先根据单幅图像提供的一些几何信息———地平面(或者是与地平面平行的平面)上两对不同方向的平行线和竖直方向的一对平行线———在图像上求得地平面的消影线和竖直方向的消影点；然后，用一个已知的参考高度来确定高度测量方程中的比例因子α；最后只要输入待测高度的端点坐标就可以获得该高度的实际值。

I was very intimate with some of them; but now they are totally immersed in worldliness.

我与他们中的一些人走得非常近；但他们现在都完全地陷进世俗中。

The results show:βdiversity is high in Mudan River,lower in Balan River and lowest in Weiken River.

在3个样条中均以河流－平原间的样地中水生植物多样性为高。

I knew that I had a facility with words and a power of facin unpleasant facts, and I felt that this cerated a sort of private world in which I could get my own back for my failure in everyday life

我知道我能熟练地运用文字，有能力面对不愉快的事实，我感到这给我创造了一个个人世界，在这个小天地地里我能补偿我在日常生活中的失败。

T tube drainage was able to decrease bile viscosity effectively.The number of bacteria decreased significantly until 21 postoperative days.The time that T tube is drawn out is on 14 postoperative days.Bacteria may exist in bile continuously and play a role on relapse of choledochitis and bile duct stone.

胆汁中的细菌和粘度升高在胆管结石形成中起协同作用。T管引流能有效地降低胆汁粘度，而胆汁中细菌量在引流术后第3周才有显著减少，临床2周时拨除T管细菌可潜伏下来，对胆管炎和胆管结石的复发可能起作用。

We investigated the saturated solubilities of NMD in various vehicles and the coeffect between all kinds of oils and surfactants.

本实验中我们考察了尼莫地平在各种介质中的饱和溶解度，以及各种油相与乳化剂配伍情况。

Andersen's magical tales werte rich as chocolate cake after a diet of wholesome gruel, and the narrative voice spoke familiarly, warmly, conspiratorially to children, rather than preaching to them from on high.

故事中的叙述者不是居高临下地向儿童进行道德说教，而是以亲切、热情的语气窃窃私语般地向儿童倾诉。

Using nuclear DNA C-values for 539 angiosperms in China, we examined the variation of these values among growth forms and taxonomic groups and the relationship of these values with invasiveness. Mean DNA C-value of the 539 angiosperm species was 4.06 pg. Mean DNA C-value was(1) significantly lower for woody species (1.84 pg) than for herbaceous species(5.02 pg);(2) significantly lower for 360 dicots (2.20 pg) than for 179 monocots (7.80 pg);(3) significantly lower for annuals (2.78 pg) than for perennials(6.65 pg);(4) significantly lower for 134 weed species (1.93 pg) than for herbaceous non-weeds (6.75 pg) and for several families that have an unusually high proportion of weed species;(5) significantly lower for 47 exotic weed species (1.76 pg) than for 134 native weeds (1.93 pg), but significantly lower than that of "non-weedy" herbaceous species (6.75 pg);(6) lower for weeds than for "non-weedy" species in same genus or family; and (7) in herbaceous species, generally lower for weedy compared to "non-weedy" species, with some exceptions such as Avena fatua, whose DNA C-value is as high as 14.15 pg, contrarily, and some "non-weedy" herbaceous species in Cruciferae and Cucurbitaceae with very low values.

统计了中国境内有分布的539种被子植物的DNA C-值，分析了它们在不同分类群、生活型、倍性、生活史类型以及在杂草和非杂草类群中的分布情况，主要结果如下：(1)539种被子植物DNA C-值平均为4.06 pg，其中木本植物的DNA C-值平均为1.84 pg，低于草本植物的平均值(5.02 pg)；(2)双子叶植物(360种)的DNA C-值平均为2.20 pg，极明显地小于单子叶植物(179种)的平均值(7.80 pg)；(3)1年生植物的DNA C-值平均为2.78 pg，明显小于多年植物的平均DNA C-值(6.65 pg)；(4)134种杂草的DNA C-值平均为1.93 pg，明显小于非杂草草本植物的平均值(6.75 pg)，含杂草较多的科，平均DNA C-值相对较小；(5)统计的47种入侵杂草的DNA C-值平均为1.76 pg，略小于134种杂草的平均DNA C-值(1.93 pg)，极显著地小于非杂草性草本植物(6.75 pg)；(6)以科为单位，不同科的DNA C-值存在着极大的差异；(7)DNA C-值与染色体倍性的关系并不明显，但是，随着倍性的增加，基因组变小；(8)在同一科、属中，与非杂草相比，典型杂草的DNA C-值往往偏小；(9)总体上杂草或杂草性强的植物，它们的DNA C-值比非杂草性植物的要小。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
