The level of tPA before and after treatment was not significantly different .Me made the conclusion that tPA had no effect on sperm\' growth , migration and maturation .However we found that the level of uPA in seminal plasma of health adult and patient had statistics difference(P.01). The health adult\'s level of uPA in seminal plasm was higher than patient\'. The level of uPA was improved after treatment and has statistics difference(P 0.01). The incrementation of upa had linear correlation with incrementation of sperm motility of

根据实验研究结果，再结合上述的病机假说，我们认为本实验证明了少、弱精性不育患者精浆中出现了"精瘀"的中医微观证，"精瘀"为其主要的病理变化；在病机演化中，肾虚是不育疾病之本，血瘀是肾虚的继发病理产物，血瘀日久会导致肾虚；并对肾虚-血瘀-不育三者关系作了理论探讨，对聚精汤的(来源：A5a2a2aBC论文网www.abclunwen.com)组成药物进行了本草析微、方义剖析，得出补肾活血法治疗此疾病不但有理论基础，也有实验依据，补肾活血法是治疗这类疾病的有效法则；还提出可以把uPA看作"精瘀"的实验指标，这对男性不育的病因分析、疗效观察、预后判断有一定的来源：A7676BC论文网www.abclunwen.com

As Oona herself was the child of a large family with its own problems, she was well-prepared for the battle that Chaplin's life became as unfounded rumors of Marxist sympathies surrounded them both — and, later on, she was the center of rest in the quarrels that Chaplin sometimes sparked in their own large family of talented children.

由于沃娜本人出生在一个被各种麻烦困扰的大家庭，她对卓别林生活中将面临的挑战也作好了充分准备，因为当时有毫无根据的流言说他俩是马克思主义的同情者。后来在他们自己的有那么多天才孩子的大家庭中，卓别林有时会引发争吵，而她则成了安宁的中心。

In the stereotyped view of the job, there's a set time to start work, another to stop.

根据对工作的传统观点，开始工作有固定的时间，结束工作也有固定的时间。

With the acquisition of historicity , these formations also acquire another crucial quality, or, more accurately, perfect a quality that was incipient as soon as A and B began the reciprocal typification of their conduct: this quality is objectivity.

随著这个历史根据的获得，这些形式也得到另一个关键特质，或者更精确地说，甲与乙一开始有行为的相互类型化时，就有了此特质的发端──即客观性。

But out of the 6,700 of the world's identified languages, nearly 2,500 are deemed at risk according to UNESCO, the UN's cultural body.

根据联合国教科文组织的数据，世界已被确认的6700种语言中，已有接近2500种被认为有消失的危险。

There was good ground, therefore, for the complaint that the religious world was thrown into disorder by the teachers who gave halakic decisions according to their own mishnaic collections (Soah 22a), since a clear and reliable Halakah could not be found in any individual compilation Shab.

有良好的地面，因此，对于有投诉指宗教世界被扔进紊乱，由老师给予halakic决定根据自己的mishnaic收藏（ soah 22A条），因为一个清晰而可靠的halakah无法找到任何单独汇编

A cDNA segment was isolated from M. meretrix larvae. The results of caspase in situ detection in larval developmental stages revealed that there were activated caspase from L1 to L3, indicating caspase is involved in the whole developmental process. The main apoptosis area was found in velum at L3 before metamorphosis, indicating the degradation of velum might be the process of apoptosis. The larvae before metamorphosis were treated by caspase specific inhibitor to analyze the role of caspase in this process. The results indicated that caspase have function metamorphosis.

根据caspase在不同物种中的保守区域设计简并引物，在文蛤幼虫中扩增到cDNA序列片段；检测有活性的caspase在文蛤幼虫各发育时期的分布部位，发现其在L1至L3期幼虫中都有分布，说明整个幼虫形态变化过程中都有caspase的参与；细胞凋亡检测结果显示，幼虫主要发生细胞凋亡的部位在L3期幼虫的面盘，即变态过程中要退化的器官，说明细胞凋亡可能是文蛤幼虫变态过程中面盘退化的主要机制；用caspase特异性抑制剂处理变态前幼虫，发现幼虫变态率下降，初步验证了caspase在文蛤幼虫变态过程中的作用。

Most of the confidences were unsought—frequently I have feigned sleep, preoccupation, or a hostile levity when I realized by some unmistakable sign that an intimate revelation was quivering on the horizon; for the intimate revelations of young men, or at least the terms in which they express them, are usually plagiaristic and marred by obvious suppressions.

绝大多数的隐私都不是我打听来的——每逢我根据某种明白无误的迹象看出又有一次倾诉衷情在地平线上喷薄欲出的时候，我往往假装睡觉，假装心不在焉，或者装出不怀好意的轻佻态度。因为青年人倾诉的衷情，或者至少他们表达这些衷情所用的语言，往往是剽窃性的，而且多有明显的隐瞒。（第1－2页）辨析原文只有一句话，由三个部分组成，有两层递进关系。

From what I can see, there is no gung-ho pro-rotation lobby in the way there can seem a rabidly anti-rotation one; just those of us who are sick of the level of criticism it receives, much of it superficial and baseless.

在我看来﹐我没有看到有任何激进的亲轮换派人士﹐有的确是很多疯狂的反轮换制派人士。跟我一样想法的人只不过是厌倦了轮换制所带来的永无止境的批评﹐当中有很多都是表明性和毫无根据的。

Results of sequence and homology analysis show that MD 1 has 97% similarity with mark in maize chloroplast genome,a gene encoding RNA maturase involved in group Ⅱ intron splicing of RNA transcript;MD2 has 99% similarity with the gene serine/threonine phosphorylase 2C in Sporobolus stapfianus;and MD3 has 99% similarity with rice the gene encoding metacaspase,an arginine/lysine-specific cysteine protease.

序列分析和同源性比对表明，MD1与编码成熟酶的玉米叶绿体基因matK有97%的相似性，MD2与极端耐旱植物Sporobolus stapfianus编码丝氨酸/苏氨酸蛋白磷酸酶的PP2C基因有99%的相似性，MD3与属精氨酸/赖氨酸特异性半胱氨酸蛋白酶类的水稻metacaspase酶基因有99%的相似性。根据MD2片段序列，结合电子克隆和RT-PCR方法，克隆出一条1731 bp的全长cDNA序列，它编码388个氨基酸。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
