It can effectively prevent cracking,by analyzing the chemical and mechanical pefformanee of this clad plate,carrying on the non-standard highest hardness test,metallographic analysis and simulation welding test,and using 890 ℃×4 h preweht air-cool heat treatment,postweld 250 ℃×2 h hydrogen removal heat treatment and final 620

通过分析该复合管板的化学成分和机械性能，并进行了非标准的最高硬度试验、金相分析和模拟试焊，采用890℃×4h焊前空冷热处理、焊后250℃×2h消氧热处理以及最终620℃×4h退火热处理措施，可有效防止裂纹产生。

From the polarity of atomic proposition, a series of CTL formulae is derived by substituting the atomic proposition with TRUE or FALSE, before they are verified by model checking tools. If one of the CTL formulae has passed the verification, then it is concluded that the system property is a vacuity.

根据原子命题的极性，用TRUE 或FALSE替换原子命题，得到一系列的CTL公式，再对这些CTL公式用模型检验工具验证，若CTL公式中有一个通过了验证，则可得出该系统属性是一个空属性。

It is an new approach of time interval and frequency measurement, which can be used to measurement short time interval by detecting the phase coincidence point between the signal and its transfer delay with related length.

这一理论利用信号的时——空关系通过对被测时间信号与其在长度空间上传输延迟的重合检测来测量短时间间隔，依此为基础可完成各种时间间隔与频率测量仪器。

By the time I got to the meeting, the only chair open was right next to Corky.

我到达会场的时候，唯一的空位子就在可奇边上。

BACKGROUND: Oxygen-derived free radicals are produced during non-enzymatic glycosylation of diabetic protein and accompanied with decrease in nitrogen monoxide synthesis so as to cause the calcium increase in cell,evacuation of pykno-granule and apoptosis induced by activating endoenzyme.

背景：糖尿病蛋白质非酶糖化过程中可产生大量的氧自由基，同时伴有一氧化氮合成下降，致使细胞内钙增加，胞内致密颗粒排空、激活胞内酶而启动细胞凋亡的发生。

For PCR product analysis area or last area of three areas (area for amplification and product analysis), direction of air flow shall be from outside to inside of the area by setting up fume hood, exhaust fan or other exhaust system in the area.

产物分析区或三个区域的最后一个区域，空气流向应由室外向室内，可通过在室内设置通风橱、排风扇或其他排风系统达到空气流由室外向室内流动的要求。

For PCR product analysis area or last area of three areas (area for am-plification and product analysis), direction of air flow shall be from out-side to inside of the area by setting up fume hood, exhaust fan or other exhaust system in the area.

2.2 产物分析区或三个区域的最后一个区域，空气流向应由室外向室内，可通过在室内设置通风橱、排风扇或其他排风系统达到空气流由室外向室内流动的要求。

In the angle of safety, economy and persistent development, how to choose the filling material to fill the goaf is presented.

从安全，经济和可持续发展的角度阐述了矿山采空区充填材料的选取原则。

The effect of heat treatment on the properties of high Cr-W cast iron was studied in this paper.

研究了热处理对高铬钨铸铁力学性能的影响，结果表明，高铬钨铸铁经980℃×2h空冷+400℃×2h回火处理可获得较高的力学性能。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
