石灰

The experimental results show that after immersion for 450 d, the samples including limestone exposed to 5％ MgSO4 solution at 5 ℃ and 20 ℃ both could produce thaumasite.

试验结果表明：掺加石灰石粉的水泥砂浆试件置于5﹪ MgSO4溶液、5 ℃及20 ℃温度环境下浸泡450 d后，均能生成碳硫硅酸钙。

Effects of temperatures on thaumasite formation were investigated.X-ray diffraction,scanning electron microscope,energy dispersive spectrum and laser Raman spectrum analysis were used to identify thaumasite in paste sample stored in 10% of MgSO 4 solution at different temperatures.

研究了环境温度对碳硫硅钙石形成的影响。降浸泡于不同温度的质量分数为10%的MgSO 4 溶液中的含石灰石粉水泥石试样进行X射线衍射分析、扫描电子显微分析、能谱分析和激光Raman光谱分析。

The results show that one type of soft slurry occurs on the surface of mortar prism due to addition of limestone filler and a mass of thaumasite and gypsum forms in the slurry.

结果表明：掺石灰石粉使水泥砂浆受侵蚀后表面呈软泥状，主要腐蚀产物为硅灰石膏和石膏，表现为典型的TSA破坏特征，其强度损失率大于纯水泥砂浆。

A limed hide was made by treating an unhaired hide with a lime solution.

生皮用石灰液处理并经过氧化氢或硫化物脱毛之后得到灰裸皮。

The relation between unhairing effect and residual sodium sulfide in limed water was studied to lead to a complete solution of sulfide, lime and organic substance pollution in unhairing and liming process.

实验首先研究了脱毛废液中残余硫化钠含量与脱毛效果的关系，从理论上和实际应用中都解决了脱毛废液中硫化物、石灰和有机物的污染，将污染消除在生产过程中。

I had the previous winter made a small quantity of lime by burning the shells of the Unio fluviatilis, which our river affords, for the sake of the experiment; so that I knew where my materials came from.

前一个冬天，我就曾经试验过，用我们的河流中学名Unio fluviatilis的一种介壳烧制成少量的石灰；所以我已知道从什么地方去取得材料了。

Orange is short of calcic disease lamina advocate fade is green near arteries and veins and Xie Yuan, fade green place produces withered spot to fall off after, vimineous top is down withered dead.

当土壤偏酸，或土壤中氮。钾。镁偏多时，都轻易造成土壤中缺钙。所以应适当施用石灰，可中和土壤中酸，提高置换性钙的含量和肥沃度，能减少缺钙症发生。

Travertine is a volcanically heated, calcium-rich flow from hot springs.

石灰华是火山的热，含钙丰富的流出热的喷泉。

Travertine is a volcanically heated, calcium-rich flow from hot springs.

石灰华是火山似的热，富有的钙流动来自于温泉。

Travertine is a volcanically heated, calcium-rich flow from hot springs.

石灰华是一个火山激烈，富钙流来自温泉。
