We have found that there are regularity changes in the Raman spectra of grossular-andradite as the rise of iron in the crystal structure from grossular to andradite after studying of Raman spectra of grossular-andradite, that is to say, their peaks shift to low wavenumber; At the same time , there are some changes in the bond angles of O-Si-O and O-Y-O:the higher of iron contents, the evidenter of splitting of two wind vibration peaks of SiO4 tetrahedron and YO6 octahedron.

通过对钙铝榴石-钙铁榴石的拉曼光谱研究发现，从钙铝榴石到钙铁榴石，随着矿物结构中铁的含量的增加，他们的拉曼光发生规律性的变化，即所有的峰向低波数方向发生漂移；同时，由于铁含量的不同使得石榴石晶体结构中O-Si-O与O-Y-O之间的键角发生了一定的变化，在其拉曼光谱谱图上表现为铁的含量越高，[SiO4]四面体和Y-O八面体的两个弯曲振动峰分裂得越明显。

The factor is organic matter both in cinnamon and Fluvio-aquio soils, while those in Burozem, Gravel blackland and Salinized soil were K+, total calcium and pH value respectively . Meanwhile, the calcium contents of apple fruits sampled from different orchards were analyzed.

不同类型土壤上红富士果实的钙素含量亦差别较大，砂礓黑土上的红富士果实钙含量达到156.83 mg/kg，极显著高于其它四种土壤，潮土上的果实钙含量次之，再次为褐土和棕壤，以盐碱土果园的苹果钙含量最低。

An important development is calcium-deoxidized steels, in which oxide flakes of calcium silicates are formed.

脱氧钙钢一个重要的发展是脱氧钙钢，在脱氧钙钢中矽酸钙盐中的氧化物片的形成。

A high efficiency decalcification agent RPD-Ⅱhas been developed for the crude with high calcium content.

针对高含钙原油开发研制了RPD Ⅱ新型高效原油脱钙剂，考察了脱钙剂注剂量、原油性质、油水混合强度、注水率和注水pH值等对脱钙效果的影响，结果表明，在剂钙比为 3～ 4时，原油脱钙率达到 90 %以上。

A high efficiency decalcification agent without phosphorus matter or metal content has been developed for Liaohe crude with high calcium content,and calcium in the crude before and after decalcification are analyzed by atomic absorption spectrometry.

针对辽河高钙原油研制开发了无磷不含金属的高效脱钙剂，利用原子吸收光谱对原油中的钙含量进行分析，考察了剂钙摩尔比、注水率、反应温度、沉降时间和搅拌时间对脱钙效果的影响。

In order to choose the suitable kind of calcium fortifier calcium-enriched food, some considerations should be fully carried out, including calcium content, solubility, absorbility and some other factors of the fortification itself, as well as the promoter of calcium absorption, the type of product and the consumer etc.

在选择钙营养强化剂时，必须充分考虑钙的含量、溶解度、吸收率、口感等钙剂自身因素，以及钙吸收促进剂、产品类型、消费对象等其它客观因素，才能实现安全、高效、经济补钙的目的。

The microstructure of an uvarovite sample was analyzed using SEM methods. Tiny quartz and chromite inclusions, calcite filling in microfractures and grossularite that forms a solid solution with uvarovite were discovered in the sample. This demonstrates that the uvarovite of eastern Tibet is of skarn origin. The spectral characteristics of the uvarovite were investigated using UV-VIS absorption spectrometry.

采用扫描电镜观察钙铬榴石样品的显微结构并进行能谱分析，结果表明其内部含有颗粒很小的铬铁矿和石英包裹体，以及裂隙中充填的方解石和与钙铬榴石为类质同象连续关系的钙铝榴石，从而为该钙铬榴石的夕卡岩成因和产状提供了佐证。

This paper aims at observing the effect of combined use of calcium antagonistwhich acts on the cell membrane and that acts intracellularly on theportal venous pressure of normal rats and that of the rat model of cirrhosis with portalhypertension, Two experiments were included in this study.

本文旨在观察细胞膜和细胞内钙拮抗剂单独与联合使用对正常大鼠和肝硬化门脉高压大鼠门脉压力的影响。实验分两部分进行：钙拮抗剂对钙离子诱导大鼠门脉压力升高的影响；钙拮抗剂预防及阻止鼠肝硬化门脉高压症的研究。

Plants were hydroponically grown in solutions containing 3 mM Ca(NO3)2 or 3 mM NH4NO3 as nitrogen source. Mature plants were harvested eight times in one day at a 3 hr. interval from 8:00PM Aug. 12 to 5:00PM Aug. 13. Diurnal variations of the shoot nitrate content were observed in either Ca(NO3)2 or NH4NO3 treatment. Shoot nitrate content of Ca(NO3)2 treated plants were higher than those treated with NH4NO3 at every harvest. The average shoot nitrate content of lettuce with Ca(NO3)2 was 0.68% of the dry weight, and it was 0.29% for the NH4NO3 treated lettuce. The fresh weight of the NH4NO3 treated lettuce were 1.43 or 1.2 fold heavier than those with Ca(NO3)2 treatment for shoot or root respectively.

R36品种以3mM硝酸钙(6mM N)或3mM硝酸铵(6mM N)处理，於8月12日下午8点开始采收，每隔3小时采收一次，采收至8月13日下午5点。3mM硝酸钙与3硝酸铵两种养液处理的地上部硝态氮含量皆有日变化，而且在8个采收时间，3mM硝酸钙养液处理的地上部硝态含量皆高於3mM硝酸铵处理。8个采收时间的硝态氮含量平均，3mM硝酸钙养液为乾物含量的0.68%，而3mM硝酸铵处理为0.29%。3mM硝酸铵养液处理的地上部与根部鲜重分别为3mM硝酸钙处理的1.43倍及1.2倍。
