Through the experiments on hydration of AH in the following sulphate（Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4）, dissoluble sulfate hydrate origining from hydration process of AH affects it's hydrous rate, hydrous rate of AH does not connect with Z/R of cation in stimulation, theory that Z/R affect hydrous rate of AH does not exist. Third, hydration of AH in dissoluble sulfate complies with dissolve-nucleate -grow theory, concentration of Ca~2+ from dissolving of CaSO_4 is higher than one of CaSO_4·2H_2O, calcium sulphate dihydrite gets a motivity of crystallization. dissoluble sulfate takes the following function: double-salt or dissoluble sulfate hydrate from hydration of AH in it becomes heterogeneous particle and a kind of nucleation catalyzer, and reduces surface barrier when DH becomes crystal because the crystal of DH precedently appears in uneven place. Results indicate hydration of AH does not conform with double-salt theory, but it conform with this mechanism: dissolve-nucleate-grow, formation of DH is an uneven nucleation and crystalizaion process.

通过对CaSO_4在Na_2SO_4 、K_2SO_4 、Rb_2SO_4 、Cs_2SO_4 、(NH_4)_2SO_4溶液中水化过程，以及CaSO_4·2H_2O、CaSO_4与以上硫酸盐反应速度、产物的研究，说明复盐理论不正确；CaSO_4在（Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO_4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4）溶液中水化，水化过程中硫酸盐水合物的析晶影响着无水硫酸钙水化，与激发剂阳离子Z/R值大小无关，阳离子的Z/R参数影响水化率的规律并不存在； 3、无水硫酸钙在可溶性硫酸盐中的水化按照溶解-成核-生长理论进行，CaSO_4达到溶解平衡时Ca~2+的浓度大于CaSO_4·2H_2O溶解平衡的Ca~2+的浓度，CaSO_4·2H_2O获得结晶的驱动力，可溶性硫酸盐起到形成晶核的作用：水化过程与CaSO_4生成复盐或析出水合物所形成的细小物相，作为异质微粒使母相中存在不均匀性，这些不均匀性有效地降低成核时的表面能位垒，使CaSO_4·2H_2O晶核优先地在这些具不均匀性的地方形成，因此这些物质起成核催化剂作用。

Fertilizing date presented obvious effects on root growth and distribution. Fertilization after watering was more primitive to the root in up-soil layers than before watering. Fertilization of Ca-Mg was positive to the increase of root in 5-15cm soil layer, but negative to that in the surface layer. Both fertilization date and Ca-Mg fertilizer affected root vigor obviously.

施肥时期对根系也具有明显的影响，与灌水前施肥相比，灌水后施肥有利于促进根系在上层土壤中的生长和分布；钙镁肥的施用能增加5~15cm土层根重，但对表层根的生长不利，施肥时期和钙镁肥施用与否对根系活力的影响也较大。

The study on the hardening mechanism of the soft soil with the materials shows that the hardening procedure can be divided into three stages:(1). Hydrating and dissolving stage, when material A and material B of the high-water-content and quick-setting materials respectively dissolve and balance in water.(2). Gel and consolidating stage, when the materials hydrate into calcium crystal and the ion exchange and aggregation of soil particles occur in an alkaline environment.(3). the structure developing stage, when the calcium crystals connect each other, absorb and crystallize the water around; the hydrate remnants, calcium hydroxide, carbonate continuously in water and in the air.

本文对高水速凝材料-软土硬化机理的研究表明，高水速凝材料-软土的硬化过程可分为三个阶段：①水化溶解阶段：主要为高水速凝材料的甲、乙料分别与水的溶解、维持平衡阶段；②胶凝固化阶段：主要为高水速凝材料的水化反应生成钙矾石晶体以及土颗粒在碱性环境中发生离子交换和团粒化作用；③强度增长阶段：钙矾石晶体相互连接，大量吸收周围环境中的水分，并将水分变成自己的结晶水；水化残余物氢氧化钙在水中和空气中发生碳酸化作用。

We understand Sunland manufactures and sells quicklime products; it also operates a trading business of quicklime products to customers as well .

我们了解，目前公司除了销售自己生产的氧化钙产品外，还从其他公司采购氧化钙并直接销售。

Quicklime is calcium oxide or calcium-magnesium oxide.

生石灰是氧化钙或钙镁氧化物。

By statistical analysis,the normal value of haircalcium and magnesium for healthy children in Jiujiang region was made.1688 children(73.39%)were found rachitis to varied degree,of which,1471(87.14%)had a low level serumal magne-sium simutaneously,The authors think that adding calcium can strengthen therapeutic effective-ness of rachitis caused by vitamine D deficiency.

通过统计学处理，制定出了我市健康小儿发钙、发镁的背景值。发现1688名小儿患有不同程度的佝偻病，占调查人数的73.39％。这组佝偻病患儿中1471例同时伴有低镁，缺镁率为87.14％。作者提出，对维生素D缺乏性佝楼病同时补充钙、镁，可提高疗效。

The calcium ion participates in the physiology function measuring cell's variety, correct the irreplaceable effect being maintaining life getting up, be not worth may arouse slow , new growth bone structure dissociation , skeleton deformation, rachitis happened if long range calcium shooting enters amounts.

钙离子还参与调节细胞的多种生理功能，对维持生命起着不可替代的作用，如果长期钙的摄入量不足，可引起生长迟缓、新骨结构变异、骨骼变形、发生佝偻病。
