  crystal water
The results suggest that the reduction in tablet hardness is dependent on the dehydration of crystal water, and the values of the slopes indicate that the bonding energy of the unpulverized sample was stronger than that of the pulverized sample.
      
As a result, a three-dimensional framework of [Ca(H2O)H2Edta)] with built-in crystal water molecules is formed.
      
Its ionic structure is composed of [NiL]2+ complex cations, ClO4- outer-spheric anions, and crystal water molecules.
      
Under storage in light, the compounds decompose from the surface; in darkness I and II are stable, whereas III and IV can lose part of the crystal water.
      
The structures are built up of [RuNOCl5]2- (I, IV), [RuNOCl4OH]2- (II, III), and [RuNOCl4(H2O)]- (IV) complex anions, (n‐Bu4N)+ cations, and crystal water molecules (III, IV).

This paper discussed some physical and chemical properties of trihydrated MgCO3 and its hydrolytic product-basic MgCO3 is obtained from NH4HCO3 reacting with MgCl2 solution. The trihydrated MgCO3 and basic MgCO3 are examined with differentia thermal gravimetric, differential thermal, infrared spectra and X-Ray diffraction analyses. Besides, we find out that the two molecules of crystal water in MgCO3·3H2O have different bonding abilities, that the structural formulae of MgCO3·3H2O and 3MgCO3·Mg (OH)2·4H2O...

Besides, we find out that the two molecules of crystal water in MgCO3·3H2O have different bonding abilities, that the structural formulae of MgCO3·3H2O and 3MgCO3·Mg (OH)2·4H2O are Mg(HCO3)(OH)·2H2O and Mg(HCO3) (OH)·Mg(OH)2·H2O respectively; and that the exothermic peak of basic MgCO3 at 515℃ has certain relationship with physical property of the product itself.

本文考察了用碳酸氢铵(或氨与二氧化碳)和氯化镁溶液所制得的三水碳酸镁及其水解物——碱式碳酸镁的热化学行为及其红外光谱,从而探讨其结构,所得结果有些尚未见有文献报导.

The Neutron Moisture Meter can give autointergral determination to average moisture content of various glass raw materials in bins. The determination has not only high precision and quick reaction but is not to be affected by the partical size and temperature of the raw materials either.As the detecting head does not touch the materials, so there is no contamination of the materials being measured.But there are some limitations with the instrument: First, the difference can not tell between crystal water...

The Neutron Moisture Meter can give autointergral determination to average moisture content of various glass raw materials in bins. The determination has not only high precision and quick reaction but is not to be affected by the partical size and temperature of the raw materials either.As the detecting head does not touch the materials, so there is no contamination of the materials being measured.But there are some limitations with the instrument: First, the difference can not tell between crystal water and free one according to total hydrogen content measured. Second, it is not efficient to determinate moisture content of the material, if its volume is small and the moisture content is very low. When to measure the material of great changeable density or the material is composed of lump the density must be reguluted.

中子水分仪可对料仓中各种玻璃原料的平均水分含量进行自动积分测定,精度高、反应快,不受物料温度及精度的影响。由于探头不与物料接触,也不会污染被测物料。其局限性是测定的总含氢量不能区分是结晶水还是自由水.不适于小体积、低水分物料的水分测定.对密度变化大或块状物料的测定必须进行密度修正。文中介绍了中子测水的原理,仪器的组成及主要性能等。

The experimental data of solubility and supersolubility of calcium lactate were determined and studied. In the experiments, it was found that the solubility curve has an abnormal point. The TGDTA results showed that one molecule of calcium lactate contains five and three molecules of crystal water respectively when calcium lactate was crystalized below and over 41℃.

研究并测定了乳酸钙的溶解度、超溶解度数据,并用多无线性最小二乘法进行拟合。从试验中发现,乳酸钙溶解度曲线有一变态点。结晶水含量测定结果表明:在41℃以下结晶得到的乳酸钙含5个结晶水,而在4l℃以上结晶得到的乳酸钙含3个结晶水。
