下降

The RRs of symptoms decreased gradually after the accident day（lag 1~5d）. The RRs of breathe hard, ocular acerbity, lachrymation and temper oppression returned to normal level on the lag 3d; the RRs of cough, phlegm, throat desiccation and nonnasality saline and sternutation returned to normal level on the lag 4d; the RR of snivel returned to normal on the lag 5d.

沙尘暴过后虽然各种症状RR均有所下降，但下降速度不同：在滞后1~2d，气短、眼睛干涩、流泪和心情压抑等4种症状RR仍显著高于沙尘暴前，直到滞后3d才恢复到正常水平；而咳嗽、咯痰、咽干口苦和打喷嚏等4种症状RR在滞后4d才恢复正常；流涕症状RR在滞后5d才基本恢复正常。

Third, by summary and analysis the factors which influence landslide stability, discovered that the landside stability evolution could divide into drop model and drop–rise model, which take the ratio of water level change speed, infiltration coefficient, specific yield as criterion.

3通过总结分析影响滑坡稳定性的因素发现，滑坡体的稳定性演变趋势可以水位变动速度和渗透系数、给水度的比值作为判别依据，将滑坡的稳定性演变规律分为下降型和下降-上升型。

As the pounds fall off—thirty in four months—Leith becomes an evangelist: his obituary of Atkins in the Guardian of April 19, 2003, is a panegyric.

随着体重下降——四个月内下降了30磅——里斯变成了一个布道者：他2003.4.19日在卫报刊登的阿特金的讣告中对其大加赞赏。

Previously, the little-understood fall had been estimated at 40-250 metres.

以前对海平面的下降知之甚少，曾经估计下降的幅度在40至250米。

Results showed that enzyme activities were significantly different, urease activity: park＞school＞residence＞industry＞road; phosphatase activity: park＞industry＞school＞residence＞road; invertase activity: residence＞park＞industry＞road＞school; But the dynamic patterns of SOC mineralization from different functional areas were similarly, the rate of SOC mineralization decreased quickly at the beginning, and then decreased slowly during the middle incubation time, and keep relatively constant during the later incubation time, and fitted to logarithmic equation with incubation time.

结果表明：不同功能区土壤酶活性差异显著，脲酶：公园＞学校＞居民区＞工厂＞道路；磷酸酶：公园＞工厂＞校园＞居民区＞道路；转化酶：居民区＞公园＞工厂＞道路＞学校；但不同功能区土壤有机碳矿化过程动态表现出相同规律，在培养前期有机碳矿化速率迅速下降，培养中期缓慢下降，培养后期保持相对稳定的趋势，有机碳矿化与培养时间符合对数关系；整个培养期内，土壤有机碳矿化速率及累计矿化量公园＞工厂＞道路＞学校＞居民区。

The ocean surface's average pH is currently estimated to be around 8.1, and to have dropped from about 8.2 since around 1800, before the industrial revolution took off, says Zeebe. A reduction of 0.1 units does not sound like much, but pH units are on a logarithmic scale, so a drop of one unit corresponds to a tenfold increase in acidity.

齐伯说：据估计，目前海洋表面的平均 pH 值大约下降到了8.1，在工业革命开始之前的1800年前后， pH 值为8.2.0.1的下降幅度听起来并不大，但是 pH 值单位利用的是对数标度，所以降低一个单位对应着酸度上升10倍。

In presence of non- cancer suspicious patients, serum MMP-2 activity in chronic hepatitis is contrary to decrease at lowest among them. The level of MMP-9 similarly low compare with normal control. Therefore found out that the process from chronic hepatitis to hepatoma, a variation of MMP-2 is earlier to decrease and then to rise. Although there is no great variation but lower in MMP-9 compare to normal control.

肝癌病人的血清中MMP-9及MMP-2两者的变化与正常人相比差距最易观察，当比较所有非癌症病人血清时，慢性肝炎病人血清MMP-2活性表现相反的下降，而且是其中最低的，因此可以看出由慢性肝炎到肝癌的过程MMP-2的变化是先下降再升高，MMP-9虽然没有大变化，相较於正常人却都偏低。

The calculating result shows that the ununiformity of fiber distribution on the shell side can lead to the serious maldistribution of flow on this side, and significant channeling effect can be observed, the flux of practical hollow fiber module is much less than that of the ideal one.

该类间歇操作模拟计算结果表明，组件通量随料液浓度的升高而下降主要是由于水的蒸汽压随浓度的升高而下降，低浓度时浓度极化的影响可以忽略；随着浓度的升高，浓度极化的作用越来越明显。

And economic benefit and to the malposition of internal and external equity allocation of enterprises on micro-level and to the declining of enterprise's value.

国家主导下的基本产权制度变迁过程中，各产权主体争夺共同财产的博弈决定着我国上市公司资本结构的演进和现状，而这种资本结构造成了：宏观上整个社会产权配置错位，国家控制了过多的社会经济资源，社会经济效益下降；微观上企业内外产权配置错位，企业价值下降。

S control of too many social and economic resources and to the decrease of social and economic benefit and to the malposition of internal and external equity allocation of enterprises on micro-level and to the declining of enterprise's value.

摘 要：国家主导下的基本产权制度变迁过程中，各产权主体争夺共同财产的博弈决定着我国上市公司资本结构的演进和现状，而这种资本结构造成了：宏观上整个社会产权配置错位，国家控制了过多的社会经济资源，社会经济效益下降；微观上企业内外产权配置错位，企业价值下降。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
