It was verified that the particle size of more than 90% of the acidic phosphorite powder was less than 4.227 μm, and more than 90% of activated phosphorite powder was less than 220 nm.

采用扫描电镜观察、X－射线衍射分析、激光粒度测试，证明了90%的酸化磷矿粉粒径为4.227 μm，90%的活化磷矿粉粒径达到220 nm。

Additionally, the crystallization of activated phosphorite powder declined, and the surface area increased.

活化磷矿粉结晶度降低，比表面积增大，有利于磷素在土壤中的释放与吸附。

The thickness of the metallic layer is in positive correction with the development of phosphorite but in negative correction with the thickness of the stone coal layer.

黑色岩系的底部为厚度不等的磷块岩层，其上为金属层或石煤层，金属层的厚度与磷块岩的发育呈正相关，与石煤层的厚度呈负相关。

It is pointed out that upwelling may be the major mechanism of phosphorite formation, and that direct source of phosphorus is pore water and bottom water in shelf region.

指出上升洋流机制可能为磷块岩形成的主要机制，磷的直接物质来源是陆架区的孔隙水和底水。

The results showed that no difference contents of calcium and phosphorous in serum between control group and experimental group.

试验结果表明，酮病阳性组牛的钙、磷含量与对照组牛的钙、磷含量相比有所下降，但差异不显著。

Many Chinese phosphorous chemical products production capacity and output in the world has become the first and second, phosphorous chemical power.

In this paper, the stereoeffect on the protein's phosphoryl transfer reaction mechanism was investigated by a model systemphosphoamino acids.

本文建立了以磷酰化氨基酸为模型化合物，定量研究磷酰基转移反应的方法，得到了以下成果

This paper also discovered that the phosphoryl transfer reactions of Nphosphoamino acids were catalyzed by imidazole with factors of 10-38, and the catalytic reaction rates could be influenced by the concentration of imidazole, structure of amino acids and alcohol.

磷酰化氨基酸的分子内N→O磷酰基转移反应具有很强的立体效应，丝氨酸与高丝氨酸，苏氨酸与来苏氨酸的反应活性分别相差6倍和1倍左右。

College of Environment and Energy Engineering, Beijing Polytechnic University, Beijing 100022, China ）Abstract The phosphoryl N → O migration reaction and ester exchange reaction on phosphorus of phosphoserine with methyl alcohol involving hexa-coordinate phosphorus intermediate 3 had been studied by MNDO method.

用MNDO方法对磷酰化丝氨酸仿生化反应机理中所形成的六配位磷中间体(3)可能的3个异构体的结构及其反应活性进行了研究。

After thehexa-coordinate phosphorus intermediate formed, the phosphoryl N→Omigration reaction would have the lowest activated energy and should be themain reaction.

六配位磷中间体形成之后，继而发生磷酰基的N→O转位反应的活化能非常低，所以它是主反应。
