In this region of convergence we find the deepest earthquakes, great topographic relief, and intensive volcanic activity . 在这种聚合地区,我们发现了最深的地震,巨大的地形起伏和强烈的火山活动。
Depending upon reaction conditions, the product may be a polyketone formed b y addition polymerization of the ketene double bond . 随着反应条件的不同,产物可以是由烯酮的双键加成聚合得到的聚酮。
Reports in the literature suggest that these derivatives can initiate various types of polymerizations in suitable circumstances . 文献中的报道指出,这些衍生物在适宜的条件下可以引发出多种聚合反应。
The arrangement of the monomers-controllable during the polymerization process-gives the material the characteristics we need . 在聚合过程中进行人为控制,使单体的排列方式能给出人们所需要的材料特性。
The dichroic agent is polymetric iodine formed by impregnating an initially transparent plastic sheet of polyvinyl alcohol with iodine and heating . 其二向色剂是聚合磺,它是将透明的聚己烯醇塑料薄片在磺内浸渍后加热制成的。
Aldehydes and other carbonyl compounds are most easily polymerized by essentially anionic mechanisms on account of the stability of alkoxide ions . 醛类和其他的羰基化合物,由于烷氧基离子的稳定性,最容易通过本质上是负离子的机理进行聚合。
Known nuclei range from the single proton in hydrogen to aggregates of more than 100 protons and 150 neutrons at the other end of the periodic table . 已知的原子核包括了从单个质子的氢到周期表的末端,由100个以上质子和150个以上中子聚合而成的核。
The third chapter discusses social organizations 第三章:社会聚合的组织纽带。
Of movement , as well as providing a converging 的运动轨迹锻? ,另提供聚合运动模式
The aggregation can be defined as being semi - additive 可以将聚合定义为半累加。
