In the three systems, system realizes the crosslinking of PVC bases on the peroxide crosslinking mechanism, the tensile strength of crosslinked PVC has been improved somewhat, the IR spectrum of gel demonstrates that there are characteristic absorption peaks of n-alcohol that belongs to ethanol amine and benzenoid group. From the analysis of gel structure , deduces that the mechanism of crosslinking reaction: under the initiations of peroxide and high temperature, PVC yields macromolecules free radicals, at the same time , styrene"s polymerization and grafting onto PVC takes place, at last the system forms crosslinking structure through coupling between radicals; confirms that triethanol amine can absorb HC1 produced by degradation of PVC, so improves the crosslinking efficiency of peroxide, decreases the HCl"s promotion for PVC"s degradation; deduces that triethanol amine can activate the PVC macromolecules and prolong the free radicals" life-time of PVC macromolecules; the effect to the PVC macromolecule makes styrenes graft reaction easy, and thus improves the crosslinking efficiency.

三种体系中三乙醇胺/过氧化二异丙苯/苯乙烯体系基于过氧化物交联机理实现了聚氯乙烯的交联，聚氯乙烯交联后拉伸强度有一定提高，凝胶红外光谱分析证实了凝胶结构中含有乙醇胺的伯醇基团特征吸收和苯环的特征吸收，由凝胶结构分析，推断出交联反应的机理：聚氯乙烯在过氧化物和热作用下产生大分子自由基，苯乙烯在过氧化物和大分子自由基的作用下发生聚合和接枝反应，最终通过自由基之间的偶合产生交联；证实三乙醇胺可以吸收聚氯乙烯分解产生的HCl，提高了过氧化物的交联效率，消弱了HCl对聚氯乙烯降解的促进作用；推断三乙醇胺可以活化聚氯乙烯大分子并有可能使聚氯乙烯大分子自由基存在的时间得以延长，对聚氯乙烯大分子的作用使苯乙烯的接枝反应易于发生，从而提高了交联效率。

Aeruginosa and S. quadricauda in HAC were lager than in HA without reference to pure or mixed culter. It indicated that the growth of M. aeruginosa and S. quadricauda need HCO3(superscript -) as carbon source to balance its C:N:P ratio. Cyclotella sp. could not survive in HAC. M. aeruginosa and S.

铜绿微囊藻与四尾栅藻在HAC中纯培养和共培养的生物量K和最大增长速率r均远大于在HA中，表明这两种藻的增殖需要HCO3作为碳源平衡胞内营养平衡；小环藻不能在有HCO3的培养基中生存。

This is not a climate-change negotiation,' said Janos Pasztor, director of the U.N. secretary-general's climate-change support team.'It's about something much more fundamental. It's about economic strength.

House s S peaker Na n cy Pelosi said while the measure was is not perfect, overall it helps keep the Americans safe and does not violate American ' s constitution al or rights.

众议院发言人南希·帕罗希说尽管措施不是完全的，然而它帮助维护美国人的安全而且没有破坏美国人的宪法或权利。

S.N.Eisenstadt exposed the logic of multiple modernities through questioning and criticizing social evolution theories after Marx's and Weber's, rethinking complex modern history, making comparative historical analysis to observe dynamical process and developing orientation of modernities from origin and the spreading to ultimate shaping.

艾森斯塔特通过对自马克思及韦伯以来的社会进化理论的质疑和批判，对纷繁复杂的现代性历史的反思，采用比较历史的研究方法考察了现代性从起源、传播到成型的动态变化过程和发展方向，揭示了现代性沿着多样性特征展开的逻辑。

Since H〓S and SO〓 adsorbed on TiO〓 could react with each other and TiO〓 is the medium of their electron transfer, thus SO〓 could not be adsorbed quite strong on the active site of TiO〓, which makes it more resistant to sulfating and increase the stability of catalyst. Finally, the model and mechanism of the reduction of SO〓 by NH〓 to elemental sulfur is advanced as follows: on the sulfide catalyst, ammonia is decomposed to N〓 and H〓, and H〓 reacts with SO〓 to form the intermedium of H〓S; then H〓S and SO〓 react as Claus reaction on TiO〓 catalyst.

反应系统中过量水蒸气的存在使催化剂表面某些活性位被水蒸气抑制使活性和选择性有较大幅度降低，但这种影响是可逆的，不会造成催化剂永久性中毒；另外当单质硫和水蒸气同时存在时，在〓催化剂上能够生成硫化氢和二氧化硫，而且由于硫化氢和二氧化硫化学吸附能力不同而导致它们的脱附顺序不同，硫化氢的生成温度总是低于二氧化硫的生成温度，说明过量水蒸气的存在会导致氧化物催化剂上逆克劳斯反应的发生；而在硫化物催化剂上几乎没有硫化氢和二氧化硫生成，说明硫化物催化剂能够抑制逆克劳斯反应的发生。
