二钙

By methods of indirectly labelling with NaH〓PO〓 and directly labelling in atomic pile, Ca〓-P, Ca〓-P, Ca〓-P, Fe-P and A1-P were isotopically labelled.

试验结果进一步证明，菌丝际的土壤pH有所降低（0.2-0.4个单位）；磷酸二钙和磷酸八钙处理的菌丝际土壤溶液中磷浓度显著地高于基他处理。

She was born weighing 6 kg 3 two to 12 kg now 22, height 61 cm, what is not normal, can be put on the钙粉drink milk in it?

她出生时体重6斤3两，现在12斤二两，身高61公分，请问是不是正常，钙粉可以放在奶粉里喝吗？

This thesis has systematically studies the microstructure of the sinter bearing fluorine of different compositions and in different sintering condition.(1) The main units of the Low Fluorine Sinter are magnetite、hematite、 SFCA、larnite、glass and pore. The cuspidine doesn't form for the low content fluorine, and the fluorine is in glass; Sinter basicity dominates the forming of the larnite and SFCA, when basicity is between 1. 72 and 1. 96, there are more larnites in the binder phase, and when the basicity is biger than 1. 96, there are more SFCA in the binder phase; the hematite appears like magnetite and usually is around pore.

为此，本文对不同组成、不同烧结条件的烧结矿样品进行了系统的显微分析和研究，其主要内容包括：(1)构成低氟烧结矿的主要组元有磁铁矿、赤铁矿、铁酸钙、硅酸二钙、玻璃体和气孔，由于含氟量的降低，枪晶石等含氟矿物并未形成，氟分布在后期凝固的玻璃体中，其中硅酸二钙和铁酸钙受碱度影响较大，硅酸二钙在碱度为1.72～1.96范围内形成较多，铁酸钙在碱度大于1.96含量增多，赤铁矿呈磁铁矿假象，多分布在气孔周围，各组元的生成顺序为：磁铁矿—硅酸二钙—铁酸钙—玻璃体。

CaO was surrounded by tricalcium silicate and dicalcium silicate with a grain size of 40 μm.

CaO被硅酸三钙和硅酸二钙所包围，晶粒尺寸在40 μm左右。

SiO2 causes early decomposition of CaSO4 due to the formation of calcium silicate and dicalcium silicate during the reaction of CaO and SiO2 at high temperature, and the formation of calcium sulphosilicate above 1200℃ helps to retard CaSO4 decomposition.

SiO2在高温下易与CaO发生固相反应形成硅酸二钙和硅酸钙使得CaSO4的初始分解温度降低，在1200℃以后硫硅酸钙的形成对CaSO4的分解有一定的延缓作用。

Based on analysis of factory converter slag,predominate phosphorus was found concentrated in a solid solution of dicalcium silicate and tricalcium phosphate,as reported in some research about slow cooled converter slags.

研究显示，如文献中对缓冷钢渣的研究结果一样，工厂稳定化处理后的转炉钢渣中的磷主要以磷酸三钙与硅酸二钙形式的固溶体存在。

The results showed that VA mycorrhizal fungi and dicalcium phosphate, octocalcium phosphate, iron phosphate, aluminium phosphate promoted growth and increased phosphorus content of corn plant.

结果表明：VA菌根真菌和磷酸二钙、磷酸八钙、磷酸铁和磷酸铝均促进了玉米植株生长，增加了植株含磷率和吸磷总量。

In the high alumina cement , dicalcium aluminate silicate is transformed into Q phase.

将高铝水泥中的惰性成分硅铝酸二钙(C2AS)转化为水化活性良好的Q相，组成Q相铝酸一钙七铝酸十二钙(C12A7)高铝水泥系统，对此系统的烧成条件进行研究。

The invention relates to coated seeds of certain plant species, the seeds having a coating for improving the efficiency of phosphorus in the plant nutrients during the early growth of the plant, the coating comprising : i an aqueous fixing agent which contains a fluid byproduct of agriculture or fermentation and possibly an emulsified oil, and ii a fertilizer powder which, depending on the plant species, is monopotassium phosphate, monocalcium phosphate, dicalcium phosphate, or urea phosphate.

本发明涉及某些植物品种的包衣种子，所述种子具有能提高植物生长的早期阶段的植物营养物中的磷效率的包衣，所述包衣含：i含农业或发酵的流体副产品和可能含有的乳化油的含水固定剂，和ii肥料粉末，所述肥料粉末根据植物品种是磷酸二氢钾、磷酸一钙、磷酸二钙或磷酸尿素。

That if the process can produce much liquid phase during the sintering, and which can become into completely-crystal needle-shap or aborization or bar-shap calcium ferrite instead of glass in the cooling process; if the magnetite is interweaved by the caking into the melting corrosion structure, the granular structure or the eutectic structure instead of exiling in the massive isolation; if the mount of the poreis is little, and uniformitly distributing; if the grain is little; if the organizational structure is symmetrical, all of which can improve the quality of the sintering.

另外还归纳出有利于强度提高的工艺参数和操作制度。分析工业试验和水钢现行生产的矿物组成、结构表明，水钢烧结矿以他形晶磁铁矿为主，铁酸钙为主要的粘结相，多形成熔蚀结构、粒状结构和共晶结构，强度较高；而在台车边缘和表层，由于存在较严重边缘效应和点火温度较低，使该区域的烧结矿组织结构疏松，局部呈蜂窝状或薄壁大孔状，铁酸钙较少而硅酸二钙和玻璃质较多，形成骸晶状结构和磁铁矿连晶，强度较低，致使返矿升高。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
