The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

For if he shall begin to fall into dotage, perspiration and nutrition and imagination and appetite, and whatever else there is of the kind, will not fail; but the power of making use of ourselves, and filling up the measure of our duty, and clearly separating all appearances, and considering whether a man should now depart from life, and whatever else of the kind absolutely requires a disciplined reason, all this is already extinguished.

因为他将在排泄、营养、想像和胃口或别的类似能力衰退之前，就开始堕入老年性昏聩，而那种运用我们自己的能力，满足我们义务标准的能力，清晰地区分各种现象的能力，考虑一个人是否应当现在辞世的能力诸如此类的能力绝对需要一种训练有素的理性，而这种性整个地已经衰退了。

DREAMED up in the go-getting 1990s, the Port Klang Free Zone was supposed to turn a medium-sized harbour into a regional trans-shipment hub that might one day rival Singapore. The project got a green light in March 1999, as Malaysia was emerging from a recession. A decade on, amid another recession, the block of reclaimed swampland sits virtually empty—and bust.

建设巴生港口自贸区的想法诞生于野心勃勃的90年代，按照设想，它将把巴生港这个中型港口发展成一个有朝一日能与新加坡相匹敌的地区转运中心。1999年5月，随着马来西亚逐渐走出经济衰退，该计划得到了政府的许可。10年之后的今天，又是一场经济衰退，这一大片填筑于沼泽之上的土地是空空如也，事实上早已停工倒闭了。

There were high positive correlations between activity of root and photosynthetic rate of flag leaf, ZRs content and activity in root, ZRs content and photosynthetic rate in flag leaf respectively.

根系活力的下降速度和叶片的叶绿素下降速度相比，根系活力的下降大于叶绿素的下降，根系活力的衰退先于叶片的功能衰退。

The results showed that for both of the alloys grains were obviously refined to same extent with increase in Ti content, and the grain sizes were coarsened to some extent due to evident fading of Ti effect during melt holding period....

随着保温时间的延长，所有合金的晶粒尺寸均不同程度发生了粗化，Ti对晶粒的细化效果明显发生了衰退。电解加钛铝合金晶粒细化效果的抗衰退能力优于熔配加钛铝合金，这种趋势对Ti的质量分数为 0 。1%～ 0 。2 %的合金特别明显。

While the stock market bubble that popped in 2000 caused only a mild recession, the housing and credit bubble has had a much greater punch — driving the unemployment rate to a high, so far, of 10.2 percent, compared with a peak of 6.3 percent following the last such downturn.

实验的结果很糟糕，当股市泡沫在2000年破裂时只导致了一次中等规模的衰退，而房产和信用泡沫的冲击则大的多－导致失业率在达到上次衰退导致的顶峰－6.3%之后，紧接着增加到迄今的10.2%。

All recessions have cultural and social effects, but in major downturns the changes can be profound.

所有的衰退都有文化和社会的影响，但是在大的衰退中这种改变是深刻的。

Based on the study of the cycling capacity degradation mechanism of the alloys, it is found that the structure stability of the alloys and their hydrides is good during cycling and has not effect on the cycling capacity degradation of the alloys.

对La〓MgNi〓等合金的循环容量衰退机制进行的研究结果表明，在充放电循环过程中，上述合金及其氢化物的结构稳定性良好，与合金循环容量衰退较快的行为无关。

He terminal cell apoptosis depended on the time of complete degradation of protoplast in cell.During PCD process,all kinds of cell organelles in protoplast promoted secondary wall deposition at different degree.

EM观察结果表明纤维、基本薄壁组织细胞、导管分子的分化过程均是典型的衰退过程，它是由次生壁的沉积和原生质体的衰退这两个密切相关的过程组成。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
