脉动流化床脱硫特性实验研究对不同初始SO_2浓度、不同初始脱硫剂颗粒平均直径、不同燃烧区温度条件下脉动与非脉动状态下流化床内的脱硫实验研究表明，Rijke型自激式脉动流化床具有类似于常规流化床燃烧器的脱硫特性：固硫剂的CaO利用率随初始SO_2浓度的增加而增加，脱硫燃烧温度存在最佳值，以及CaO利用率随脱硫剂颗粒平均直径的增加而减小。

The calcium is in the life each growth stage, from childhood to the adulthood is to went to the old ages to all carry to emphasize to want the physiology function, the thesis is mainly from the existence of the calcium inside the human body, the physiology function of the calcium ion, the human body is to the absorption of the calcium ion, supersession, regulation mechanism to calcium ion etc.

钙在人生各个生长发育阶段，从幼年到成年乃至老年都肩负着重要生理功能，论文主要从人体内钙的存在，钙离子的生理作用，人体对钙离子的吸收、代谢及调节机制等方面来写。

In this paper, the marine soft soil is mixed with 10% cement added with 0.5% NaOH and 0.5% Na2CO3 separately, which form two types of new cement-soils. Comparing with the undisturbed soil and the 20% cement-soil results in that the alkalescence additive can contribute to generate a large number of needle-like, rod-like or fibriform hydrate calcium silicate crystals. The hydrate calcium silicate crystals can inhibit the generation of calcic alum crystal which would bring expansive action. At the mean time, it can separate out hydrate calcium. The hydrate calcium silicate crystals and hydrate calcium constitute the filling and inclusions together among soil particles and on the surface of soil particles, which cut down the interstices of cement soil obviously. Therefore, the soil mass can be reinforced and the intensity can be improved.

现场试验中将海积软土与分别掺入0.5%NaOH和0.5%Na2CO3的10%水泥就地搅拌，形成两种新型水泥土，在与原状土及20%纯水泥土进行比较后，发现碱性外掺剂可以促使生成大量针状、棒状或纤维状水化硅酸钙晶体，抑制了能产生膨胀作用的钙矾石的生成，同时，有Ca2晶体析出，它们共同构成土颗粒间和土颗粒表面的充填物和包裹物，使水泥固化土的孔隙明显减小，密度和强度得到极大提高。

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。

The above results indicate that the release of CGRP evoked by ETX from the sensory fibbers of rat spinal cord is dependent on extracellular calcium. After entering into the cell through the N-type voltage dependent calcium channel, calcium binds to calmodulin, and triggers calcium release from intracellular calcium store by activating the caffeine-sensitive mechanism.

提示内毒素引起离体大鼠脊髓感觉神经纤维释放CGRP，依赖于细胞外〓的存在，〓主要通过N-型钙通道进入细胞后，与钙调蛋白结合，激活细胞内对咖啡因敏感的钙池〓释放，从而引起CGRP释放。

To investigate the effects of serum calcium and phosphorus on the model of calcium-deficient laying ducks, one hundred and twenty Shan sheldrakes were allocated into normal diet, half calcium carbonate and quarter calcium carbonate groups randomly. Serum calcium and phosphorus were detected by automatic biochemistry analyzer one day before and one, three and five weeks after fed with above diets.

将120只600日龄产蛋山麻鸭随机分为正常日粮组、1/2石粉组和1/4石粉组，自动生化分析仪测定更换饲料前1 d及更换饲料后1、3、5周血清钙、磷水平，观察缺钙日粮对蛋鸭血清钙、磷的影响。

In order to extend use of calcium carbonate, the samples were modified by hydrazine hydrate, triethanolamine and sodium stearate. Hydrazine hydrate was 0.08%～0.24% of calcium oxide, triethanolamine was 0.1%～0.3% of calcium oxide, sodium stearate was 5% of calcium carbonate,modification time was 40 minute. Calcium carbonate has better active exponent and white degree.
