Methods This study contained a total of 16 culture groups, including one group as control and 5 groups treated by 5 drugs (calcium L-threonate, sodium L-threonate, alendronate, 17β-estradiol and calcium gluconate) each at the final concentrations of 10^(-9)mol/L, 10^(-7)mol/L, 10^(-5)mo1/L respectively. After 7 days, eight bone slices of every group were stained with toluidine blue and the areas of resorptive pits were analyzed under light microscope; the concentrations of C-telopeptide of type Ⅰ collagen CT(subscript x or Crosslaps in culture supernatants were measured by ELISA.

制备骨磨片，培养OC，并分别加入高中低浓度10^(-5、10^(-7)、10^(-9)mol/L的L-苏糖酸钙、L-苏糖酸钠、阿仑麟酸钠、17β-雌二醇、葡萄糖酸钙，实验设以上各浓度组及对照组（共16组，每组n=8），甲苯胺蓝染色一光镜观察分析骨片上骨吸收陷窝面积，ELISA测定上清液Ⅰ型胶原C-末端肽（CTx或Crosslaps）浓度。

If it is exclusive breastfeeding, nursing mothers can serve calcium, milk-fed babies have a calcium deficiency symptoms should calcium agents, such as calcium gluconate, milk half an hour after feeding, a sub-fed two or three times better absorption and also cod liver oil should continue to serve on weekdays Rideau sun 9:00 choose a more moderate after the sunlight, as much skin exposed limbs, to the best of direct sun to sun, the sun through the window glass was not effective, it should also be noted, In addition, when the sun of the need to protect your baby's eyes, not straight into the sun.

如果是纯母乳喂养，乳母可以服钙剂，奶粉喂养的宝宝有缺钙的症状就要补钙剂，比如葡萄糖酸钙，奶后半小时喂，一支分两三次喂吸收较好，另外还要继续服鱼肝油，平日里多晒太阳，选择上午9点后比较温和的阳光，尽量多露出四肢的皮肤，要直接晒到太阳最好，透过窗户玻璃的阳光没有效果，这点要注意，另外晒太阳时注意保护宝宝的眼睛，不能直对着阳光。

Because the body cannot produce Calcium,a balanced diet,regular exercisr,healthy lifestyle choices and adequate intake of Caicium can play a roke in maintaining bone health.

因为人自身不能产生钙，饮食平衡、定期运动、选择健康的生活方式和摄入足够的钙在保持人类骨骼健康方面起着重要作用。

AIM: To systematically investigate the effects of sarcoplasmic reticulum Ca2+ content depletion on cardiac Ca2+ release.

目的：较系统地肌浆网内钙容量的减少对心肌细胞钙释放的。

AIM摘要: To systematically investigate the effects of sarcoplasmic reticulum Ca2+ content depletion on cardiac Ca2+ release.

目的摘要：较系统地探究肌浆网内钙容量的减少对心肌细胞钙释放的影响。

It is the fast Ca 2+ release channel of the sarcoplasmic reticulum.

钙释放通道又称ryanodine受体，是细胞内质网膜上介导细胞内钙信号转导的离子通道。

This is a new way for comprehensive utilization of waste fat and oil. The dropping points of lithium grease and lithium-calcium complex grease can be improved through adding the complex additives. Oxalic acid and sebacic acid are effective on lithium grease' and lithium-calcium complex grease' respe...

采用加入复合剂提高锂基润滑脂和锂-钙基润滑脂的滴点，加入草酸复合剂对所制备的锂基润滑脂的滴点的提高最为有效，加入癸二酸复合剂对锂-钙基润滑脂的滴点提高效果最好。

PMW-PT, PNW-PT and PMW-PNN-PT ceramics with pure perovskite structure were prepared by the Semichemical Method or the Hydrothemal-Derived Precursor Method.

采用半化学法或水热前驱体法制备了纯钙钛矿结构的PMW-PT、PNW-PT和PMW-PNN-PT基弛豫铁电陶瓷粉体，探讨了钙钛矿相陶瓷粉体的形成机理，系统研究了各种影响因素对粉体或陶瓷的相组成、显微结构和介电性能的影响。

Most of small intrusive bodies are stocks or dikes, and each of the dimension is less than 1km2 ; they are mostly granite-porphyry、porphyritic-granite、monzogranite,a small amouts of them are quartz diorite or diorite; the chemical characters are high content of SiO2、K2O and low content of Mg and CaO, on the SiO2-K2O diagram all the samples fall in the field of high-K calc-alkalic series and shoshonite series.

小岩体多呈岩株或脉状产出，出露面积多数在1km2以下；岩性主要为花岗斑岩、似斑状花岗岩、二长花岗岩，少量为石英闪长岩及闪长岩等；岩石化学成份以高硅、富碱、多钾、贫镁、少钙为特征，属高钾钙碱性系列或钾玄岩系列。

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