钙华

We're able to provide granite, marble, slate, sandstone, quartzite, limestone, andesite, basalt, travertine, lava of China origin, but also able to supply granite, marble, limestone or travertine from all over the world, such as America, Brazil, Italy, Spain, Portugal, Norway, Australia, Finland, India, Saudi Arab, Iran, Turkey and so on.

我们还可以提供花岗岩，大理石，板岩，砂岩，石英石，石灰石，安山岩，玄武岩，钙华，熔岩的中国血统，而且还能够供应花岗岩，大理石，石灰石或钙华来自世界各地，如美国，巴西，意大利，西班牙，葡萄牙，挪威，澳大利亚，芬兰，印度，沙乌地阿拉伯，伊朗，土耳其等。

Another use of oxalic acid is in the final polishing of onyx, marble, and travertine.

另一种使用的草酸，是在最后的抛光玛瑙，大理石，和钙华。

Carbonate rock saprolite is formed in zones of alteration and made up of travertine and residual carbonate crystals.

碳酸盐岩腐岩形成于包气带，由原岩中的碳酸盐溶解后再次沉淀形成，主要由钙华和残余碳酸盐晶体组成。

The world's biggest travertine beach land

世界上最大的地表钙华滩流

Before this alkaline lake went dry, tufa formed when a freshwater spring percolated from below and formed calcium carbonate deposits.

在此之前，碱性湖泊变为干燥，钙华形成时，淡水喷泉过滤从下面，并形成碳酸钙的沉淀。

The aptly named Art collection features travertine tiles in a range of modern metallics like gold, copper, silver and iron, or in mother of pearl, red and violet finishes for a more modern twist on an antique look.

在恰当命名的艺术收藏的功能像黄金，铜，银，铁，或在母亲的现代金属色瓷砖范围钙华珍珠，红色和更现代的扭曲紫完成对古董看看。

However, in recent yean, the landscape come to be dried up. Blacken, sanded, which have seriously affected the sight's admiring value. It is Very important to take the landscape measures and control human activity to research the rules and influencing factors of travertine. It will be good to society, economy.

但近年来黄龙钙华出现了干涸、变黑、沙化等现象，严重影响了景观的可观赏性：深入研究该区的钙华演变规律和影响因素，对于采取科学的保护措施，控制人为活动时钙华资源的不利影响将其有重要作用。

Before this alkaline lake went dry, tufa formed when a freshwater spring percolated from below and formed calcium carbonate deposits.

在此之前，碱性湖泊变干燥，钙华形成时，当淡水泉过滤来自下面，并形成碳酸钙的沉淀物。

Comparison of the same Southwest monsoonal climate areas and the same study period with Dongge Cave and Kahf Defore Cave in δ18O values, the tufa core of δ18O in Huanglong is higher extent than these of Cave records, which altitude effect and different removal of moisture source regions maybe lead to extent difference in δ18O values; and we can draw a conclusion the tufa core records of Huanglong in the high altitude and middle latitude areas is more sensitive respond to climatic environmental changes than records of stalagmites in Dongge Cave and Kahf Defore Cave from the low altitude areas.

同属西南季风区、由于海拔效应和距离水汽来源远近不同等因素的影响，在同时段内黄龙钙华δ18O 的变化范围和变化幅度都比董歌洞和Kahf Defore 洞的δ18O记录要大，说明处于中纬度、高海拔的黄龙钙华相对于低海拔的董歌洞和Kahf Defore洞石笋对气候环境的响应可能更加敏感。

Being high in Li, Be, Mo, Ga, Rb and Cd contents and low in Cu, Pb and Zn contents in sinters of gold mineralization can be used as an indicator for further prospecting.

地表热泉沉积物主要是硅华和钙华及其过渡类型，大多数是硅华和钙华的混合堆积物。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
