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。

Only 1O-day pretreatment of germinated seeds at 5℃ or 10℃ was enough to enhance the floral bud differentiation in the spring variety'Duanye 13', whereas at least 20-day pretreatment was required for the promotion of floral bud differentiation in the winter variety'Yidianhong'. Non-vernalized'Duanyi 13'plants flowered 70 days after transplanting in a warm (above 15℃) and long photoperiod (16h) growth condition, but non-vernalized 'Yidianhong'plants did not flower 90 days after transplanting in the same growth condition as'Duanye 13'.
处理温度越低和/和处理时间越长,对花芽分化和开花的促进作用越明显;春性品种'短叶13'的萌动种子在5℃和10℃条件下处理10d就能显著促进其花芽分化,而且即使未经低温处理,并给予15℃以上的生长温度和16h的长日照条件,植株也能在播种后70d内开花;但冬性品种'一点红'则需要在5℃或10℃下处理20d以上方能显著促进花芽分化,若不给予低温处理,即使给予16h的长光照条件,在播种后90d也不能开花。

Thus we conclude that JA might be one of the potent factors, other than auxin, involving in the regulation of LR formation.3. Relationship between JA and SA on LR formation in rice seedlingMouse monoclonal antibodies against salicylic acid was produced and characterized for the first time. The McAb S2-8F, were derived from an immunogen in which 5-aminosalicylic acid (5-ASA) was conjugated to KLH (hemocyanin from keyhole limpets) through its-NH2 group.
实验结果还表明IBA对水稻幼苗侧根发生的促进作用可能并非是通过转化为吲哚乙酸(indole-3-acetic acid,IAA)而实现,因为外源IAA不能促进水稻幼苗侧根的发生,荣莉酸对水稻幼苗侧根发生的诱导效应及其与生长素和水杨酸的关系却和 IBA一样可以抑制种于根伸长及促进侧根伸长,只是IAA具有这种效应需要的浓度是IBA的20多倍。3。
