The apparent weight of calcium,the length and weight of the rats,and the length,weight,bone density and calcium content of the femurs were measured in every group.

将SD大鼠随机分成6组，分别喂养氨基酸钙复合物、碳酸钙和低钙饲料，通过测量相应饲料喂养大鼠的身长和体重，钙表观吸收率，以及股骨的长度、重量、骨密度、钙含量指标，观察氨基酸钙复合物对SD大鼠骨密度的影响。

Experiments on decalcification and activation of osteoinductive ability, comparison between the osteogenesis of demineralized bone matrix in orthotopic and in heterotopic sites, and correlation between immune response to allograft of bone and osteoinductive activity of the graft, were reported in this paper. 1. Syngeneic deminerolized bone matrix and the mixture of DBM with bone ash or acid-soluble protein extracted from demineralization was implanted into muscle pouch of mice, subsequently, the inhibition of DBM osteoinduction by bone ash or acid-soluble protein was demonstrated with histological and by means of alkaline phosphatase assay.

本文对脱钙处理使骨诱导活性表达的作用、脱钙骨基质植入不同部位的成骨表现，以及同种异体骨移植引发的免疫反应与骨诱导活性的内在关系三方面进行了研究：（1）在小鼠肌肉植入同系脱钙骨基质及其与脱钙所去除的骨矿盐和酸溶性蛋白混合物，碱性磷酸酶和组织学检查表明：骨矿盐和酸溶性蛋白具有抑制脱钙骨基质骨诱导活性的作用。

Under drought stress, 5mmol/L and 10mmol/L Ca~(2 ) test can increase thecontent of endogeny calcium, then improve the drought resistance of strawberry. And5mmol/L Ca~(2 ) test can increase the content of endogeny CaM, because CaM adjustinner enzyme activity, improve the drought resistance of strawberry.

在干旱胁迫下，5mmol／L和10mmol／L钙处理能提高草莓内源钙含量，从而提高草莓的抗旱性。5mmol／L钙处理能提高草莓内源钙调素含量，是由于钙调素调节了体内酶的活性，从而增强了草莓的抗旱性。

The results of magnesium and calcium ions tolerance test indicated that the modified SPS, synthesized from the above two methods,has good chelation with magnesium and calcium ions for the crablike carboxyl and ester group and increase the reaction weight with magnesium and calcium ions for addition of hydrophilic group.Both of the two modified petroleum sulfonates could produce ultra-low interfacial tension at calcium and magnesium ions concentration lower than 600 mg/L,whereas the general petroleum sulfonates could only produce ultra-low value below 300 mg/L.

耐钙镁离子能力测试结果，以大庆炼化公司两种渣油为原料，采用上述两种合成方法制备的改性石油磺酸钠，由于产物中引入蟹爪状羧酯基，对钙镁离子有较强的螯合作用，同时增加了亲水基，增大了表面活性剂分子与钙镁离子的反应量，因而在600mg/L的钙镁离子溶液中获得10-3级的超低界面张力；而普通石油磺酸钠仅能在300mg/L的钙镁离子溶液中获得超低界面张力。

The origin of glauberite attributes to various processes, including(1) direct crysllization from sulphate solution;(2) substitution of glauberite for gypsum;(3) transformation from hydrous glauberite; and(4) ion exchange between sodium sulfate and calcium-bearing mud.

钙芒硝的成因可归纳为：(1)直接从硫酸盐溶液晶出；(2)交代石膏成因；(3)从卤水中先沉积水钙芒硝后脱水变为钙芒硝；(4)硫酸钠溶液与含钙淤泥之间发生离子交换而生成。与菱镁矿紧密共生产出于海相地层之钙芒硝很可能形成于潮坪盐湖环境。

Solubility and stability of calcium arsenates under different CO2 pressures are studied based on the data of precipitation and solution experiments simulated by PHREEQC program. The result shows that calcium arsenates can dissolve incongruently by the effect of CO2 in high pH（pH〉8. 3）and make their solubility higher. The higher the CO2 pressure is, the lower the acidity of the incongruent dissolution is.

文章摘要：通过沉淀和溶解两方面的实验数据，应用PHREEQC程序模拟了砷酸钙在不同CO2分压条件下溶解度的变化情况，发现环境中的CO2可使砷酸钙盐在酸度较高（pH大于8.3）的条件下发生不一致溶解，使其溶解度升高；CO2分压越大，砷酸钙盐发生不一致溶解的酸度越低；CO2主要影响3：2和5：3的砷酸钙盐，而对4：2砷酸钙盐的影响较小。

The process of translocating Ca2+ from fruit surface into pulp tissue could be accelerated by IAA,GA or NAA, which also led to an increment on 2%HOAc extractable Ca. Meanwhile, the Ca existed in the stalk and leaves could be excessively transported into fruits by applying IAA on the fruit surface, resulting in too much accumulation of Ca in fruit and bad quality of fruit, while no such effects were observed in those with GA or NAA.

IAA、GA和NAA均可促进果面钙运往果实内，并导致2%HOAc提取钙与5%HCl提取钙组分增加，IAA虽可促进大量的树体钙向果实转移，却会导致果实钙含量过高，品质变差；GA和NAA则不能夺取树体内的钙，对果实品质无不良影响。

Inorganic calcium mainly calcium carbonate, calcium citrate, calcium lactate, calcium gluconate and other classes of organic calcium.

无机钙主要是碳酸钙，柠檬酸钙，乳酸钙，葡萄糖酸钙和有机钙的其他类。

The calcium sulfate was dissolved and led to the rapid increase of calcium ion concentration in the solution. So the calcium sulfate is not suitable for being seed crystal of low-salt concentration. The quartz sand and calcium carbonate both can be used as seed crystals, but it is much faster and more complete to use calcium carbonate as seed crystal compared with using quartz sand.

当硫酸钙加入处理液中发生了硫酸钙溶解现象，导致溶液钙离子浓度迅速增加，故硫酸钙不适合做低浓度盐水的晶种，而石英砂和碳酸钙均能对钙离子的结晶起到效果，但碳酸钙做晶种对钙离子的结晶更快捷、更彻底，在条件允许的情况下，采用碳酸钙做晶种为宜。

Vitamin D_3 levels are generally considered imperative for mineral metabolism in most animals, particularly to the surface-dwelling animals, because of its central role via mediating absorption and reabsorption of mineral respectively in intestine and kidney, and direction to the skeleton mineral.

维生素D是哺乳动物维持机体钙磷平衡的基础，维生素D促进小肠对钙磷的吸收，肾脏对钙磷的滤过、重吸收，钙磷在骨骼中的沉积与释放，在钙磷代谢中具有决定性调节作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
