It is also the main factors to control the abundances of noncrystal phase. The typical feature is that the elemental concentrations in this speciation and the percentages of this speciation in samples have significantly variation down the core, especially there is a sharp change at the depth of 80cm.

3铁锰氧化物结合态是除残渣态外的又一元素主要赋存形态，是控制元素在非晶质结合态中赋存的主要因素，同时也是岩芯不同深度沉积物中元素含量和萃取比例变化最大的一个相态。

All ofthese reactions were carried out under mild conditions and are new effective methodsfor the preparation of indolizine derivatives. The reaction of phthalazinium and quinoxalinium N-ylides with electron-deficientolefins in the presence of oxidants have also been studied, it has been found that activemanganese dioxide could behave as a dehydrogenating oxidant. Pyrrolo[2,1-a]phthalazines and pyrrolo[1,2-a]quinoxalines are obtained in this way.

The main species of the antimony catalysts are antimony trioxide, antimony acetate and the recent widely concerned ethylene glycol antimony.

此外，用于酯交换反应的锰、锌、钙、钴、铅等金属的醋酸盐对缩聚反应也有一定的催化作用。

The exponential regularity of the shock wave attenuation coefficient versus the charge diameter in PMMA was obtained by fitting experimental data.

利用锰铜压阻传感器法测量了某聚奥传爆药在不同直径下的小尺寸装药爆轰输出冲击波经不同厚度有机玻璃隔板衰减后的冲击波压力，通过对实验数据进行拟合，得到了有机玻璃介质中冲击波衰减系数与装药直径的指数型关系。

Meso-Tetrakis(2,6-dichlorophenyl)porphyrinmanganese chloride and carbonyl ruthenium meso-tetrakis(2,6-dichlorophenyl)porphyrin were prepared and used to catalyze the diastereoselective epoxidation and amidation of 3β-substituted Δ 5-steroid derivatives.
