Under the 6 h stress, SOD activity had been to maintain a high level, POD activity showed a greater change. When the stress lasted until 24 h, POD activity decreased and almost flatted compared with the control, this showed that POD activity was sensitive under the low temperature stress. Changes of CAT and SOD activity were in the line, the results indicated that activity of two enzymes coordinated the regulation of low-temperature adaptation.

本实验中，SOD活性一直保持较高的水平；POD活性表现为波动较大，当胁迫持续到24 h时，POD活性明显降低几乎与对照持平，说明POD受低温影响更敏感；CAT活性与SOD活性变化保持一致，表现出这两种酶在低温适应性调节过程中的协同作用。

国内外有关喷丸强化后残余应力的松弛行为及规律研究很少，尤其是对超高强度结构材料的研究更少，因为在工程应用上存在着一个普遍的认识，即：材料的强度越高，残余应力越稳定ls。

Nevertheless, as to the antioxidant activity, HA andβ-PPA could also protect cells against oxidative stress within a relatively short duration time when compared to α-Toc. TS didn't show any effect against oxidative stress in the range of our treated doses. In the remanding experiments, all of HA,β-PPA and TS didn't show any activity in the protection of rat primary hepatocyte cells against H2O2-induced oxidative stress, and in the inhibition of telomerase.

在前骨髓白血球HL-60程式化死亡系统中，HA会诱发HL-60的程式化死亡，β-PPA和AMBL-029C-TS只会直接诱发细胞的坏死，在观测抗氧化效果方面，以对HL-60细胞不呈细胞毒性的浓度观察，得知HA和β-PPA在短时间内有保护细胞不受氧化压力的能力，但在长时间后，对抗氧化压力的效果不如α-Toc明显，AMBL-029C-TS则没有明显抗氧化压力的能力。

After soil slaked, in view of the effect of soil slaking deformation, stress and stress level evidently drop. The difference of maximal principal stress on the bottom of waterishlogged field between before or after slaked goes nearly to fifty percent in the case.

分析了在堤基为上强下弱、堤基为深厚的强透水层等多种情况下，各种垂直防渗墙（全封闭式防渗墙、半封闭式防渗墙和悬挂式防渗墙）的适用条件和防渗方案的优化等，同时探讨了防渗墙的渗透系数对防渗效果的影响。

5The height, length of leaves, width of leaves, fresh weight of single plant, fry matter weight of single plant, leaf areas of single plant, LAI, yield of single plant and yield components were reduced during drought stress at different growth stages. The decreased percent was the most great to grains per corncob at tasseling drought stress; hundred-grain-weight, at grain stage drought stress; yield of single plant, at booting-blossoming, and the extent was

不同生育时期干旱胁迫处理春玉米株高、平均叶片长度、平均叶片宽度、单株鲜重、单株干重、单株叶面积、叶面积指数、产量及产量构成因子均有不同程度下降。

Recently, it is found that the neuron apoptosis caused by brain ischemia is associated with signal pathway of endoplasmic reticulum stress, which is different from the traditional apoptotic pathway. Caspase-12 has been identified as a molecule which initiates apoptosis selectively in response to ER stress and is not activated by other pathways. Caspase-12 is localized on the ER membrane, but once specifically activated by ER stress, it translocates to the cytoplasm.

最近的研究发现，这种细胞凋亡与内质网应激(endoplasmic reticulum stress ER stress)有关，其是一种不同于经典的凋亡途径的新途径，分子伴侣葡萄糖调节蛋白78(glucose regulated protein， GRP78/Bip)表达增高是反应ER stress的最敏感的指标，胱冬酶-12(caspase-12)为鼠源性的内质网膜上的蛋白，它的特点是只被内质网诱导的凋亡所激活而不被其它非内质网因素所激活。

The data from stress box indicate that the observed values usually are smaller than the theoretical ones, and the relationship between the vertical or lateral stress and the fill soil thickness can be described in a power function curve: a- a hb. The fact that the soil stress is bigger in the portion adjacent to the central part of gully and becomes smaller in the portion close to the side illustrates that the gully has an apparent unburdening effect. From the monitoring results of the settlement deformation during and after constructingperiod, the study conducts statistical system analysis and evaluation on the change of settlement with time.
