减弱

In physiolgoical state,the action of traditional RAAS on blood pressure might be decreased with age in aged people,and the vasoactive peptides might contribute more to the cardiovascular action to keep blood pressure stable. Activity of vasoconstrictive peptides were incresaed and activity of vasodilative peptide was decreased.

老年人随着年龄的增长，在生理状态下传统的RAAS的作用减弱，更多的是血管活性肽(ANP，ET，CGRP)参与心血管活性的调节，老年EH患者缩血管肽ET的活性增高、舒血管肽CGRP活性减弱。

The dynamic changes of the the neuron apoptosis and correlative genes in hippocampus of ACET-groups and twice-ACET-groups suggested that ACET can slower the apoptosis by inhibiting p~(53)and prolong the ascending period of p~(53) in 4 days after the seizure,this effect would weaken after 4 days.ACET may inhibit the descending of Bax,prolong its descending period and then promote its expression,in order to weaken the inhibition of the apoptosis during 4 to 10 days after seizure and then promote the apoptosis during 10 to 14 days after.This effect of ACET can be enhanced after treating again within 7 to 14 days later.

埋线组和二次埋线组大鼠海马神经元凋亡及相关基因表达的动态变化结果提示：埋线治疗在癫痫发作后的早期(4d内)可通过抑制促凋亡基因p~(53)蛋白表达、延缓其达峰值的时程，从而减缓神经元凋亡的发生，此作用在4d后减弱；埋线治疗抑制大鼠海马神经元凋亡的作用在癫痫发作后的中期(4d～10d)减弱，甚至在远期(10d～14d)出现促进凋亡的作用，可能是通过抑制Bax蛋白表达的下降、延长其降至低峰值的时程，促进Bax蛋白表达的回升的结果；在中远期(7d～14d)内予二次埋线治疗对该效应有续效叠加的作用。

Initially it is crisis alone that attenuates the role of political institutions as we have already seen it attenuate the role of paradigms.

最初只有危机减弱政治制度的作用，就象我们已经看到它减弱范式的作用一样。

After dialyzing for 10～20 min, SNP at a concentration of 1 μmol/L increased the induced responses to innocuous mechanical stimulation and decreased those to noxoius mechanical stimulation. The induced responses to both innocuous and noxious mechanical stimulations were all decreased after dialyzing the same dose of SNP for 20～30 min. The decrease was shown within 7～15 min dialysis when SNP was used at a concentration of 20 μmol/L.

脊髓深层神经元透析1 μmol/L SNP， 10～20 min后，非伤害性机械刺激诱发的反应增强，伤害性机械刺激诱发的反应减弱；透析20～30 min后，伤害性和非伤害性机械刺激诱发的反应均减弱；透析20 μmol/L SNP 7～15 min内伤害性和非伤害性机械刺激诱发的反应均降低。

Following anovulatory dose of hCG, the positive reactivity of Cyclin G1 in preovulatory granulosa cells was decreased. Furthermore, the luteinized granulosa cells showed the weak staining.

至排卵前卵泡颗粒细胞，Cyclin G1表达水平减弱，当颗粒细胞分化为黄体细胞后表达水平进一步减弱。

The crushed rock in the side abutment weakens the side restriction while the side wall and the apron strengthen the side restriction. The analysis showed a new stress distribution with automatic modification and less stress concentration when the side restriction is weakened by using crushed rock in the abutment.

结合某碾压混凝土拱坝的拱座，在减弱和加强侧约束时，即在坝体部分高程的破碎软弱岩石减弱坝体侧约束以及坝体下游边墙和护坦增强坝体侧约束的情况下，研究侧约束对于坝体应力和位移的影响。

The larvae on different development stage indicated different sensitivity to reactive oxygen species, the napuli VI showed the most sensitive. 2 Antioxidants could decrease the damage effect of reactive oxygen species on larvae in certain level.The addition of antioxidants in culture system had risen larva suvival rate and the metamorphosis rate of cyprid .

外源抗氧化剂的加入在一定程度上减弱了活性氧对东方小藤壶幼虫的伤害作用，从而提高了幼虫的存活率和变态率；在减弱活性氧对东方小藤壶幼虫的伤害作用中，不同类型的抗氧化剂对不同类型的活性氧所起的作用大小不同。

Specifically, the science-majored college students tender to mastery goal orientation. In the test of mastery goal, the junior students get the highest score; the senior undergraduates get the lowest score. There shows a tendency that mastery goal firstly gets strengthen and then gets weaken gradually along with the grade elevation in the college students. In avoid performance goals, the junior students get the lowest score, the senior undergraduates get the highest score. There shows a tendency that avoid performance goals firstly get weaken and then get strengthen gradually along with the grade elevation.

具体表现为：理科大学生更倾向于掌握目标定向；在掌握目标上，大三学生得分最高，大四学生得分最低，大学生掌握目标随年级升高呈现出逐渐增强又减弱的趋势；在成绩回避目标上，大三学生得分最低，大四学生得分最高，大学生成绩回避目标随年级升高呈现出逐渐减弱又增强的趋势。

同时 ，在 Al2 O3载体中引入 Ti O2 后，能明显减弱 Al2 O3上 L酸的强吸附部位，从而减弱了 Al2 O3载体水合反应的能力，提高了催化剂的抗水合性能

In this article, the effect of different water pH (pH 5, 6, 7, 8, 9)on the secretion of nacre of freshwater pearl mussel Hyriopsis cumingii were studied with histochemical methods and transmission electron microscopy.

结果表明：在中性水环境中，贝体能积极地从外界水环境中吸收钙，并能旺盛地合成和分泌贝壳珍珠层及珍珠有机基质前体物质；持续的酸性水环境导致贝体的钙严重丢失，并引起珍珠质分泌细胞对有机基质前体物质的合成和分泌能力减弱；持续的碱性水环境虽能导致贝体对钙的积累，但珍珠质分泌细胞合成和分泌珍珠质有机基质前体物质的能力减弱；水环境的酸性或碱性程度越高，对珍珠质分泌细胞的合成和分泌活动的影响越大。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
