It is included that 4-5 types of active sites exist in the catalytic system and the active site produced polymer with low molecular weight is easy to be activiated while TEA is used as the cocatalyst. While TIBA, the active site produced polymer with high molecular weight and seldom active site produced polymer with low one is prone to be activiated. MAO tends to activiate the active site produced polymer with middle-level molecular weight. In TEA-TIBA catalytic system, TEA and TIBA activiate the corresponding active site and the weight of every active site gradationally varied with the change of the ratio of the two cocatalysts. And the activity of the active site produced polymer with high molecular weight is proportion to the concentration of TIBA.

发现：TEA作为助催化剂时产生低分子量产物的活性中心易于活化，且体系中具有活性的活性中心有4～5种；TIBA易于活化产生高分子量的活性中心，基本上不能活化产生低分子量产物的活性中心；MAO对产生中等分子量产物的活性中心活化能力较强；在TEA-TIBA混合物体系中，TEA和TIBA各自对活性中心的作用表现为明显的互补现象，各活性中心的相对强度随着两种助催化剂之间的比例改变呈现渐次变化，其中产生高分子量产物的活性中心的相对活性(来源：c5AB3fC论文网www.abclunwen.com)与TIBA的浓度有明显的正相关性。

E. , approximately four months; 2 the active periods occur much longer than the non-active periods; the main climatic characteristics of the non-active periods, compared with the active periods, is weaker monsoon with westerlies at 850-hPa and easterlies at 200-hPa on the deviation fields of circulations over the SCS (active time minus non-active time); it is warmer in the active periods than in the non-active periods at lower and upper levels; 3 in most circumstances, the low frequency vibrations of the summer monsoon and its rainfall are quite in phase.

2其中活跃期出现时间要比非活跃期长的多。与活跃期相比非活跃期主要气候特征表现为季风的减弱，在环流的偏差场上在南海上空850hPa上为西风，200hPa上为东风，活跃期高低空都比非活跃期要暖一些。(3)在多数情况下夏季风和夏季风降水的30-60天的低频振荡比较一致。

The comparative studies of lithogeochemistry for the volcano-intrusive complexes both from Jiulongzhang and from xiangshan reveal that the chemical compositions of the volcano intrusive complexes in the two areas are very close, and the trace element spidergrams and REE patterns basically coincide with each other. It is also shown that the two volcano-intrusive complexes have the same source features and the active continental margin tectonic settings. At the same time, it is found that, from early volcanic magma activities to later intrusive magma activities, the content of SiO2 and the Rb/Sr ratio decreased, on the contrary, the content of MgO and the ratios of K/Rb, Ba/Rb and LREE/HREE increased. It is shown that the hypabyssal or ultra-hypabyssal intrusives are not the products of the volcanic magmatic differentiation.

两地区的火山－侵入杂岩的岩石化学成分及其变化特点极为相近，微量元素蛛网图和稀土配分型式也基本一致，它们具有相似的岩浆过程和统一的活动陆缘构造背景；同时，从早期火山岩浆活动到晚期浅成－超浅成岩浆侵入活动，其w(SiO2)和w/w的值降低，而w以及w/w、w/w和w/w的值增高，晚期浅成－超浅成侵入岩与早期火山岩没有直接的分异演化关系。

active volcano：活火山

由于岩浆中含大量挥发分,加之上覆岩层的围压,使这些挥发分溶解在岩浆中无法溢出,当岩浆上升靠近地表时,压力减小,挥发分急剧被释放出...活火山(active volcano) 一般来说,只有活火山才会发生喷发.
