The effect of 60 Co γ\|ray irradiation on growth of Cymbidium sinense rhizome and shoot regeneration were studied.

本文报道了用60 Coγ射线辐照对墨兰根状茎生长和分化的效应。

Under the same condition as methane partial oxidation, the reaction results are as follows: CH4 conversions is 88%, CO selectivity is 90%, H2 selectivity is 68%, CO2 selectivity is 12%.H2-TPD indicates that it is difficult for H2 to desorb from catalyst. It is estimated that the reaction between hydrogen and oxygen being absorbed is the primary approach to produce H2O, and it maybe lead to the lower H2 selectivity.

反应结果如下：CH4转化率88%；CO选择性90%；H2选择性68%，CO2选择性12%。H2-TPD实验表明，H2在催化剂表面难于脱附，表面氢与表面氧反应可能是生成H2O的主要途径，这也可能是H2选择性比较低的原因。

The bands of gem-dicarbonyl CO gradually decreased in intensity and fully desorbed at 300℃ during TPD dynamic process.

在TPD动态过程中，孪生CO谱带强度逐渐减弱并在325℃完全脱除。

Herein the latest developments of olefin aqueous polymerization which are mainly promoted by late- transition metal catalysts are reviewed including ethylene,α-olefins, cyclo-olefins and dienes polymerization, along with ROMP of cyclo-olefins and CO/olefins copolymerization.

本文综述了后过渡金属催化剂水相催化烯烃配位聚合的一些新进展，内容包括烯、α-烯烃、环烯烃、二烯烃的聚合反应和环烯烃的开环聚合反应以及CO/烯烃的共聚反应等方面。

The specific surface area of the material prepared at 900℃ by dopping Co or Ni in the position "B" of the La_4BaCu_5O_13＋δ is increased about 10% than that of the material prepared by the traditional method.

BET测试表明，在La_4BaCu_5O_13＋δ A位掺Sr可在一定程度上增大材料的比表面积，而在A位掺Ce 则不利于材料比表面积的提高。900℃在B位掺杂Co、Ni合成的材料的比表面积比传统的方法制备的材料的比表面积提高了近10%。

The XRD spectrum of the material prepared by dopping Co and Ni in the position "B" of the La_4BaCu_5O_13＋δ, indicates that there are still some foreign matter phase at 750℃ and the material has a single perovskite-like structure at 900℃.

XRD测试图谱表明在La_4BaCu_5O_13＋δ B位掺杂Co和Ni的材料在750℃以下时材料中则仍会有部分杂相存在。

The grain size of the material prepared by dopping Sr in the position "A" or dopping Co or Ni in the position "B" of the La_4BaCu_5O_13＋δ is small but it becomes bigger by dopping Ce in the position "A" of the La_4BaCu_5O_13＋δ.

SEM测试表明材料的粒径随着温度的升高而迅速增大，但颗粒的分布比较均匀。A位掺Sr和B位掺Co和Ni时合成的材料的粒径较细小，而A位掺Ce时合成材料的颗粒较大，这与BET测试和孔径分布测试相一致。

The changes are a result of the spin-polaried injection of Co and the magnetic filed effects, both of which increase the fraction of siglets among the total excitons, and the former one is primary.

效率的增强是Co的自旋极化的注入和磁场效应共同作用的结果，其中自旋极化注入起主要作用。
