衰退

In contrast with the rapid nucleus degradation, cell organelles in cytoplasm, such as rough endoplasmic reticulum, amyloplast, and mitochondrion, maintained their metabolic functions for a longer time.

在核衰退的同时，其胞质中的粗面内质网、淀粉质体和线粒体等细胞器具有正常的代谢功能，细胞仍在合成并积累营养物质，淀粉胚乳细胞一边衰退一边行使其功能，直至死亡。

In the process of nucleus degeneration, cell organella, for example, rough endoplasmic reticulum, amyloplast, and mitochondrion, maintained normally metabolic functions in cytoplasm, and nutrient substance was still synthesized and accumulated at the time of nuclear degeneration, the starchy endosperm cells carried out their functions until cell death simultaneously.

在核衰退的同时，其胞质中的粗面内质网、淀粉质体和线粒体等细胞器具有正常的代谢功能，细胞仍在合成并积累营养物质，淀粉胚乳细胞表现出一边衰退一边在行使其功能，直到细胞死亡。

We're uncertain at this point whether this slowdown after the most recent recession is going to be temporary, as it was after preious recessions before 1990, or whether it will be longer term, such as we saw after the recession in the early '90s, said Aaron Catlin, also a CMS economist and the lead author of the study, which appears in the current issue of Health Affairs.

Aaron Catlin，也是CMS的经济学家，即将在保健事务的最新一期发表研究文章的主要作者。他说"我们并不确定这种发生在经济衰退以后的医疗费用减慢趋势是否暂时的。就像1990年前的衰退所看到的，或者是否更长时间。"

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。

In TRPL we did not observe the constant decay time even at low temperature.

测量的衰退时间常数在30K时为3.6ns，这是我们所知道的最长的衰退时间常数。

Calcium deposits were localized on the vacuolar membrane and in the nucleus of nucellar cells at the early degenerative stage, then they were also observed on the plasma membrane including vacuolar membrane and nuclear envelope at the middegenerative stage.

初始衰退的珠心细胞，Ca〓主要分布于液泡膜上和核内；在衰退中期的珠心细胞中，Ca〓主要分布在核膜、液泡膜及质膜上；在严重衰退的珠心细胞，Ca〓仅存在于液泡中。

We still expect Japan's upswing to resume in the first half of 2005 and support overweighting Japanese equities and the yen.

日本刚公布的经济成长率连续两季下滑，按理论而言，日本景气应算是过去十四年来的第三次衰退，但事实不然，日本景气并不那么恐怖，美国运通认为日本景气仍在上升的轨道上，所以建议在日本股和汇市再加码，虽然2004年整体日本经济成长为2.6%，但在下半年则度过一个浅碟的衰退，这个衰退有很大的原因是来自于日本在下半年遭受到台风的侵袭，使得消费支出减少，是气候的影响而非经济的实际改变。

The current decay of CO oxidation at Pt SPE gas sensing electrode in short time scale has been studied.

对短时间内Pt－SPE气敏电极上CO氧化电流的衰退现象的研究表明，Pt表面无CO吸附态情况下，衰退主要与电极阳极极化后Pt表面氧化程度加深有关；采用动电势扫描法可使电极对CO氧化的催化活性基本恢复，但随着电极的进一步极化，衰退仍会继续。

The result is still a deep recession, similar in length and depth to the 1975 and 1982 recessions.

预测结果仍然是严重的经济衰退，衰退周期和严重程度与1975和1982年时的经济衰退大体相同。

With a supporter in Mr Charest and an admirer in Mr Dumont, Mr Harper may be encouraged to call an election himself.

由于在沙雷那边有个支持者，杜蒙那边有个崇拜者，鼓励哈珀为自己举行一次选举。
