Ultimatums, bringing up past pain andunresolved issues, jealousy, or unusual neediness or possessivenessmay all be part of the scenario, and what makes all of this quitestressful is that most of it is not blatant but subtle andinsidious.

最后通牒：提起过去的伤痛与未解决的问题，嫉妒，不同寻常的穷困与占有欲都有可能成为这次的剧情。这些因素会造成关系紧张的原因是他们并不明显反而微妙且阴险。

Generally, the air leakage in condenser can be attributed to tube and valve imprecision of vacuum system or deficiency or even intermittence of steam seal pressure. Besides, it is probably engendered by low-efficient air ejector, which cannot totally extract the air leakage in condenser.

空气漏入凝汽器的原因，通常是由于真空系统管道阀门不严密或汽封压力不足甚至中断所造成的；也可能由于抽气器效率降低，不能将漏入凝汽器的空气完全抽出而造成的。

Macrophanerophytes such as pine and cedar are more and occupie greater percentage to from bottom to top, which are affected by clime and geography and human avtivity. Because people pay more attention to Macrophanerophytes and less to shrub and herbge plants, ecology of the forest is unbalance and benefit is low.

在整个沉积物柱的孢粉组合中，松、杉等大型乔木始终占有很高的比例，而且越到上部比例越大，这除了受滇中地区气候地理因素的影响外，可能还有人为的原因，人们在保护森林资源和植树造林过程中往往只是注重了大型的乔木而忽视了灌木和草本植物，从而使森林生态失衡，生态效益低下。

I got carried away And not just by balloon: Wonderful They called me "Wonderful" So I said "Wonderful"- if you insist I will be "Wonderful" And they said "Wonderful" Believe me, it's hard to resist 'Cause it feels wonderful They think I'm wonderful Hey, look who's wonderful - This corn-fed hick Who said:"It might be keen To build a town of green And a wonderful road of yellow brick!"

我带走 而不是仅仅由气球：精彩的他们叫我&奇妙&所以，我说：&奇妙&-如果你坚持我将&奇妙&他们说：&奇妙&请相信我，这是难以抗拒'的原因，感觉奇妙他们认为，我是奇妙嗨，看看谁精彩-这种玉米喂养希克谁说：&这可能是渴望要建立一个镇的绿色和美好的道路黄色砖！&

Backyard breeder: A dog owner whose pet either gets bred by accident or who breeds on purpose for a variety of reasons. This breeder is usually ignorant of the breed standard, genetics, behavior, and good health practices.

&后院&繁殖者：一个狗主人，他可能是因为意外或者多样的原因进行了繁殖，这种繁殖者通常会忽略这个品种的标准，基因，行为表现，和有益的健康的锻炼。

Background and Objectives: Keloid is benign hyperproliferative collagen formation in response to skin trauma. Although the pathoetiology of keloid formation remains unclear, over reaction of the TGF-β pathway is believed to be a mechanism. In this study, we survey the differences in clinical presentation and the change in molecules of the TGF-β pathway after pulsed dye laser therapy.

背景及目的： Keloid组织除在临床上造成外观问题，也有痛或痒的困扰，但是及造成原因并不明确，很多研究指出和TGF-β路径有相关性，临床上治疗方式有很多种，染料雷射是其中之一，在临床治疗提供显著的改善，所以研究对於TGF-β路径其中分子的影响，及其可能的机转为何。

Specific protein bands were observed in cellular and extracellular protein electrophoresis for both strains 593 and 18.There were also different protein expression in certain protein bands.It is indicated that a significant difference existed between the proteome of strains 593 and 18.This difference may contribute to the different cariogenic potential of these two strains.

两菌株的菌体和菌外可溶性蛋白电泳图谱中均可见各自特异表达的蛋白条带，且部分相同位置的蛋白条带在蛋白表达量上也存在差异，表明两菌株的蛋白组存在明显差异，该差异可能是导致其致龋力差异的原因之一。

However, they are more likely to suffer from an interrupted night's sleep because of health problems - forcing them to adapt by catnapping, or coping with tiredness in the day, the research showed.

不过，由于某些健康方面的原因，这些上岁数的人可能会承受夜里睡眠被打断的痛苦，并迫使他们适应这种小睡生活，同时还要应对白天的疲倦。

Prolonged intake of melamine will damage animal reproduction and urinary systems, bladder/renal stones will further induce bladder cancer.1994 International Programme on Chemical Safety and European Commission coedited International Chemical Safety Manual Vol.3 and International Chemical Safety Cards specify that:: prolonged or repeated intake of melamine might influence kidney and bladder, giving rise to stones. The preliminary investigation of 2007 America pet food contamination incident regards that wheat protein powder doped with ≤6.6%%melamine is the cause of pet food poisoning.

动物长期摄入三聚氰胺会造成生殖、泌尿系统的损害，膀胱、肾部结石，并可进一步诱发膀胱癌。1994年国际化学品安全规划署和欧洲联盟委员会合编的《国际化学品安全手册》第三卷和国际化学品安全卡片说明：长期或反复大量摄入三聚氰胺可能对肾与膀胱产生影响，导致产生结石。2007年美国宠物食品污染事件的初步调查结果认为：掺杂了≤6.6%%三聚氰胺的小麦蛋白粉是宠物食品导致中毒的原因。

"Maggot therapy was more effective and efficient in debriding nonhealing foot and leg ulcers in male diabetic veterans than was continued conventional care," the authors write."In addition to issues of efficacy and safety, future studies also must address the cost-effectiveness of maggot debridement therapy and conditions in which is likely to be futile."

蛆虫疗法在处理男性糖尿病患者足部伤口溃疡的清创效果比传统疗法更为有效，也更安全，研究人员认为未来对於蛆虫疗法的研究最好能放在其对清创治疗的成本效益（cost-effectiveness）分析，以及可能使它无效的原因为何。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
