硝酸钙

Injecting calcium nitrate into sediments is a new technology of in-situ treatment developed in the late 10 years.

受污染底泥的修复已经成为水环境修复中的重要组成部分，在底泥中注入硝酸钙则是近10多年来发展起来的一种污染底泥原位处理技术。

Therefore, 5 mmol/L calcium nitrate and treated for 12 h could delayed the maturation and consenescence process of muskmelon.

因此，5 mmol/L硝酸钙，并且处理12 h具有较好地减缓网纹甜瓜果实衰老的作用。

Muskmelon discs taken at ripening stage were used by different concentrations of calcium nitrate (1, 3, 5 mmol/L) and various time (4, 8, 12, 16, 20, 24 h) in order to investigate related to maturation and consenescence physiological parameters.

为明确钙在调节网纹甜瓜果实成熟衰老中的生理作用，以网纹甜瓜果实圆片为材料，研究了不同浓度硝酸钙(1，3，5 mmol/L)处理4，8，12，16，20和24 h情况下，甜瓜果实成熟衰老相关生理指标的变化。

Muskmelon discs taken at ripening stage were treated with different concentrations of calcium nitrate 1, 3 and 5 mmoloL^(-1 and various time (4, 8, 12, 16, 20 and 24h) in order to investigate the fruit softness and the relative physiological parameters.

以网纹甜瓜果实圆片为材料，研究了不同浓度硝酸钙1， 3， 5mmolL^(-1处理4，8，12，16，20，24h情况下，甜瓜果实软化及其相关生理指标的变化。

"The term is also used for sodium nitrate and calcium nitrate, both of which are used in the nitric acid industry and as fertilizers, and for ammonium nitrate, a high explosive and fertilizer"

这一名词也用于表示硝酸钠和硝酸钙，此两者在硝酸工业中被当作肥料使用。硝石也指硝酸铵，一种高爆炸性炸药和化学肥料。

Calcium sprays were effective ifdone correctly, and our results indicated both calcium nitrate and calciumchloride were effective calcium sources Fig.

我们试验结果显示硝酸钙和氯化钙是十分有效的钙来源。

The working conditions of equipments, the mediums and their concentrations, and the interference of coexisting ions were investigated. The results showed that when the flame was shielded with oxygen enriched, the barium in lapis lazuli could be determined using calcium nitrate as releasing agent in 5% nitric acid. The obtained results were satisfied.

对仪器的工作条件、介质及其浓度、共存离子的干扰进行了探索，结果表明，在富氧屏蔽火焰条件下、体积分数为5%硝酸介质中，以硝酸钙作释放剂，测定天青石中的钡，可获得满意结果。

Salt solution approximate 10^(-1M treatments were more effective in the inhibition of elongation. Fiber formation and lignification were also inhibited to various degrees by salt solutions.

以10^(-1)M左右的硝酸镁、硝酸钙、硝酸钠溶液处理，嫩茎的抽长被抑制得更多；纎维化和木质化也受到明显的抑制。

Six Treatments of foliage sprays on 18-year-old satsuma mandarintreeswith 1000 ppm calciferous solutions plus 5 ppm GA_3 thrice at interval of 15 days before fruitcoloring reduced intensively the occurrence of peel puffing.

以18年生枳低砧温州蜜柑为试材，采用叶面喷施，分别设醋酸钙、硝酸钙、碳酸钙各1000ppm，另在以上3种试剂中各1000ppm加5ppm赤霉素(GA_3)及清水对照共7个处理，于果实将近着色时，每半月喷施1次，共喷3次。
