酸模

The testing results showed that the higher Shore A hardness, tensile strength, elongation at break, modulus at 100% elongation of MMg/NBR vulcanization were obtained when compared to those of C.B./NBR system; and the presser-resistant property of packer-rubber can be improved for 5Mpa with new structure.

结果显示：与炭黑/NBR体系相比，在过氧化物硫化体系下，甲基丙稀酸镁可以有效补强丁腈橡胶，MMg/NBR硫化胶的邵A硬度，拉伸强度，扯断伸长率和100%定伸强度均较高；新设计的胶筒结构简单合理，易卸模，成品率高，并通过模拟试验发现，新的结构形状可以有效改善胶筒的抗破坏性能，耐压差性能平均提高5MPa。

Objective To evaluate the effect of dimensional accuracy of alginate and silastic and polyether impression materials after immersion in a new disinfectant and provide evidence for clinical application.

目的：研究新型浸泡消毒剂浸泡后，对藻酸盐、硅橡胶和聚醚精细印模材料尺寸稳定性的影响，为临床应用提供依据。

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。
