In range of 300℃~900℃, all the transition metal oxide catalysts could get high ammonia conversion, during the initial stages of the reaction, the SO〓 conversion is relatively low since the catalysts have not been sulfureted, but it increases gradually and attain constant with rising temperature and time continuance,〓 is better than other catalysts in reactivity and elemental sulfur selectivity; XRD indicates that, in the SO〓-SCR process, stable transition metal sulfide is generated which is very important to SO〓 reduction and transition metal sulfide probably is the active phase of catalyst, further the reduction of SO〓 by H〓 to H〓S is the limiting step of all process, then the activity is somewhat related to its lattice oxygen yet not so notable; XPS indicates that little sulfur on surface exists as S〓 in sulfate, showing that TiO〓 could restrain the generation of sulfate.

对于过渡金属氧化物催化剂的研究发现,在300℃~900℃范围内,不同的催化剂均可获得很高的NH〓转化率,反应初期由于催化剂还未硫化,所以SO〓的转化率较低,随着温度升高和反应时间的延续,SO〓的转化率逐渐升高并达到了稳定值;七种过渡金属氧化物中,以〓对于NH〓还原SO〓反应的活性和选择性最好;XRD结果表明在NH〓-SO〓反应后生成了稳定的硫化物相,硫化物对SO〓的还原过程具有重要作用,催化剂的活性相可能是过渡金属硫化物,而且在硫化物催化剂上进行的H〓还原SO〓生成H〓S的反应是整个过程的速率控制步骤,所以催化剂的活性与其自身的晶格氧的氧化还原能力有一定的联系,但关系不明显;XPS结果表明催化剂表面的硫大部分以过渡金属硫化物的形式存在,只生成少量的S〓,说明TiO〓催化剂能够较好的抑制硫酸盐的生成。

The net photosynthetic rate was significantly negatively correlated with intercellular CO2 concentration.

The results show:(1) After soybean seed is treated with seed coating, The length of lateral root anlage Initiating area obviously increases in contrast with control (seed which is not coated with agent is regarded as control; shortened form is CK).The order is from greatness to smallness in turn as follow: HK>ND>CK.(2) Initiating progress of lateral root anlage is quickened when seed is treated with seed coating. General trend is as follow: HK>ND>CK. By variance analysis, treatment and control has obvious difference.(3) Initating status of lateral root anlage is definite related with contents of endogenous hormone. Occurring of lateral root is as the result of some endogenous hormone corresponded and playing manysided role, especially IAA plays important role in the cause of inducing to occurring of lateral root anlage.(4) The use of seed coating may elevate the number of lateral root anlage occurring and shorten the time of lateral root anlage occurring, especially the effect of Chemical control seed coating is better.

结果表明:(1)种衣剂包衣后,侧根原基发生区长度明显比对照(不包衣的种子为对照,用CK表示)增加,从大到小依次为:HK>ND>CK;(2)种衣剂处理加快了侧根原基的发生进程,总的趋势是HK>ND>CK,经F检验表明,处理和对照差异极显著;(3)侧根原基的发生状况与侧根原基发生区内源激素的含量有一定的关系,侧根的发生是几种植物内源激素相互协调、综合作用的结果,其中生长素类物质在诱导侧根原基的发生过程中起主导作用;(4)应用种衣剂可以提高侧根原基发生的数量,缩短侧根原基的发生时间,其中以化控种衣剂效果最好。

Research on Keeping Quality of Different Flesh Types of Prunus persica L.Niu Liang, Wang Zhiqiang, Liu Shu'e, Song YinhuaAbstract: Effects of post-harvest cold storage and Modified Atmosphere Package on fruit hardness, weight losing and soluble solid content of different peach or nectarine varieties were investigated. The results showed that:(1) There were obviously differences of fruit hardness among varieties of different flesh types. In room temperature, FH of '24-30' and 'Zhongtao No.2' went down slower than 'Zhongyoutao No.5' and 'Zhongyoutao No.10'. In cold storage, '24-30', FH of Zongyoutao No.5' and 'Zhongyoutao No.10' descent quickly after 2 weeks of storage while that of 'Shuguang' and 'Zhongtao No.2' quickly descent just after storage.(2) MA package could effectively slow down the decreasing of FH. There were obvious differences among different varieties while 'Zhongyoutao No.10' was less sensitive than others.(3) Soluble solid content went down after harvest and the procedure was slower in lower temperature. In room, MA package seems accelerate the descendent of SSC.
