结果表明，二段硫化温度越高，硫化时间越长，胶料的拉伸强度和定伸应力越大，硬度越高；而撕裂强度、伸长率、拉断永久变形以及压缩永久变形越小，其中胶料的硬度、拉伸强度、伸长率、压缩永久变形在一定时间后基本上趋于平衡，较好的二段硫化条件为150℃～160℃×3～4h。

Reactive oxygen species causing DNA oxidative damage comes from two kinds of ways:one is from cellular normal physiological metabolism;the other is from outer environment.Redox-sensitive green fluorescent protein was expressed in Saccharomyces cerevisiae.Recombinant cells were evaluated in monitoring the changes in the redox state of living cells when challenged with toxicologically relevant metal ions NaAsO_2 or Pb(NO_3)_2 by measuring emission intensity at 510 nm with a Hitachi F6500 fluorescence spectrophotometer,roGFP expressed in yeast responded not only to typical membrane-permeant oxidants H_2O_2 and reductants DTT,but also to toxicological metal ion-induced intracellular redox changes in a dose-dependent manner.Moreover,exposure of yeast cells to NaAsO_2 or Pb(NO_3)_2 at concentrations that induced redox changes reported by roGFP caused up to 2～3 fold increases in DNA mutation frequency.This mutagenic effect was largely caused by oxidative stress since blocking the production of hydryl radicals with thiourea significantly reduced the mutation rate as well as delayed the cell death.

本文将对氧化还原状态变化敏感的绿色荧光蛋白roGFP1-R12，在酵母细胞中实现了多拷贝强表达；荧光扫描经强氧化剂H_2O_2和还原剂DTT以及环境中重金属NaAsO_2或Pb(NO_3)_2处理后的酵母细胞悬液，测定510 nm处的荧光发射强度结果显示，表达的绿色荧光蛋白对氧化还原水平敏感，且在510 nm处的荧光强度与一定的重金属浓度呈正相关，即roGFP1-R12在510nm处的荧光发射值随重金属浓度的增高而增强，从而说明重金属对细胞的毒性在一定程度上很可能是通过破坏细胞内的氧化还原平衡发生作用；同时通过该绿色荧光蛋白对胞内氧化还原状态变化的响应情况可以来实时检测环境中的重金属；遗传学的点突变频率及致死率实验数据表明，重金属能导致菌体的点突变频率和致死率升高，且活性氧的清除剂巯基脲能明显降低这种点突变和致死率，说明由重金属引发的这种点突变和致死效应在很大程度上是依赖于重金属对细胞诱导产生的氧化胁迫。

Methods Thirty-four ears with traumatically perforated tympanic membrane and 57 ears of secretory otitis media with incised tympanic membrane were selected.

During underbalance drilling gas reservoir is opened gradually,gas is in the shape of spherical from formation into annular flow and bubbles will be inflation migration,so radius of bubbles formation is important for the annular fluid.

欠平衡钻井过程中气层逐渐被打开时，气体将以小气泡的形式从地层进入环空流体中，气泡进入环空后将膨胀运移，变成大气泡，因此气泡生成半径对环空流体的流动规律有重要影响。

The experiment is done based on a glass cell and all the results are quite in agreement with the theory. The decay process of the background vacuum pressure caused by the untrapped cesium atoms after shutting off the desorption light is well explained quantitatively.

As the environment gets worse and worse,humen begun to realize that the wolves were so wise,beacuse the wolves didn't kill out their hunt in order to hold the balance of nature.even we can compare the wolve to the cleaner in nature.

在环境恶化后，人类才意识到狼有多么聪明，因为他们不会对猎物赶尽杀绝，以维持生态的平衡。甚至我们可以称其为自然界的清道夫。

The sliding wedge, behind the retaining wall of not reaching the limit displacement, can be divided into numerous differential slices paralleling to the sliding plane. Then, with the force analysis of these differential slices and the relationship mentioned above, equations can be set up and the inclination of the sliding plane is also derived. Thereby, the calculation formula of the nonlimit active earth pressure is obtained.

对于未达到极限位移的挡土墙，结合已取得的位移与摩擦角之间的关系，采用与滑裂面相平行的微条对墙后滑动楔体进行划分，对微条进行受力分析，建立平衡方程，推导了滑裂面的倾角，从而得到非极限主动土压力计算公式。

Using the fractional ultrasonic-extraction on four different-rank coals, including lignite, coking coal, low- and mid-metamorphism anthracites by different solvent, isotherm adsorption experiment was made after equilibrium-water accessioned into raw coals and their residues. The change of the adsorption capacity and its affecting factors were analyzed combined with the pore-structure and equilibrium-water content measurement.
