钙

In the presence of hypoalbuminemia, although total calcium level may be low, the ionized calcium level may be normal

在低白蛋白血症的时候，血清总钙水平已经低于正常，但离子钙水平仍可在正常范围内。

The lower the serum albumin, the higher the portion of the total calcium that is present in ionized form.

血清白蛋白越低，血清钙中离子钙的比例就越高。

Baby is so small, and ate formula, in your doctor confirmed that he did not receive calcium or zinc circumstances, is best not to blindly supplement, calcium, zinc premium will lead to more sexually precocious child!

孩子这么小，而且吃的是配方奶，在你没有得到医生确认他缺钙或锌的情况下，最好不要盲目地补，钙、锌补多了会导致孩子性早熟！

Compared to carbonate, phosphate is more propitious to the decomposition of calcium molybdate.

从热力学角度来看，在钼酸钙分解过程中，添加磷酸盐比碳酸盐更加有利于钼酸钙的分解。

From the development of the Carboniferous reefs, the metazoan framework reefs and the reefs dominated by microbes and calcareous algae may be two parallelling evolution reef ecosystems. The development of the metazoan framework reefs after the extinction event reflects an obvious evolutionary lag time. The recovery of the reef-building communities dominated by microbes and calcareous algae became faster after the extinction event.

从石炭纪整个生物礁的发展情况来看，后生动物骨架礁与以微生物和钙藻为主导的生物礁或许是两个平行发展的礁系统，后生动物骨架礁的发展在大规模生物灭绝事件之后有明显的演化滞后现象，以钙藻和微生物为主导的造礁群落的复苏在生物灭绝事件之后更为迅速。

In vivo, CXCR4-A549 and A549 cells were injected subcutaneously into nude mice(each group in 6).Four weeks later the mice were scarified and the tumors in situ and the lungs were taken out to be examined histologically.(3) Th cell cycle distribution was measured by flow cytometry to analyse the effect of SDF-1/CXCR4 in the cell proliferation and atoposis. The changes of the intracellular calcium concentration after SDF-1 activation were aslo measured by flow cytometry. Western blot was used to anlayse the phosphorylation of AKT and ERK, and the expression of MMP-2 and VEGF-C.

3为探讨SDF-1/CXCR4在肺癌侵袭和转移中的作用机制：①利用流式细胞仪检测CXCR4-A549与A549两组细胞的增殖和凋亡，分析上调CXCR4的表达后，对细胞生长周期的影响；②利用流式细胞仪检测两组细胞钙离子内流强度，分析SDF-1/CXCR4对钙离子通道活性的调控；③采用Western blot实验检测两组细胞PI3K/AKT、MAPK/ERK相关信号通路的活性，分析SDF-1/CXCR4可能激活的下游信号分子；④采用Western blot和RT-PCR检测两组细胞肿瘤转移相关基因VEGF-C、MMP-2的表达，探讨SDF-1/CXCR4与VEGF-C、MMP-2的相互作用关系。

The development of metal-air battery and air electrode is briefly introduced in this paper. Then, the catalysts for oxygen reduction, especially perovskite-type oxide, are reviewed in detail. Meanwhile, the principle of sol-gel technology is summered, and then their preparation with Sol-Gel method has been briefly introduced.

本论文简述了锌-空气电池及空气电极，介绍了金属-空气电池用催化剂特别是钙钛矿型复合氧化物催化剂的研究现状及进展，并对溶胶-凝胶制备法制备钙钛矿型复合氧化物作了简要的介绍。

High alumina cement system ; Q phasealumina calcium-7 alumina 12 calcium system ; sintering ; compressive strength

高铝水泥； Q相铝酸一钙七铝酸十二钙系统；烧成；抗压强度

In the samples containing aluminum sulphate, some ettringite crystalparticles are formed, which do not match with dihydrate gypsum crystals and increase thedefects in the hardened plaster. The strength decreases sharply with increase of aluminumsulphate amount.

硫酸铝的引入，使石膏浆体中生成部分钙矾石晶体，钙矾石晶体与二水石膏晶体不匹配，从而增加了硬化体内部的缺陷，因此，随着硫酸铝掺入量的增加，硬化体强度的降低比较严重。

300Mg Calcium L-threonate containing 40mg 〓Ca was given to the subjects shortly after intravenous injection of 4mg 〓Ca chloride solution. Urine samples were collected for 48 hours, and purified by precipitation of ammonium oxalate.

研究中，14名受试者在空腹状态下口服〓Ca标记的L-苏糖酸钙咀嚼片（含300mg元素钙，其中〓Ca 40mg），同时静脉注射含有4mg 〓Ca的氯化钙溶液，分段收集给药前和给药后48小时内的全部尿样。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
