侵蚀

Wulingyuan has many huge rocks with strange appearance, some of them are very dangerous and steepy: they gather together, just like many coral come out from the deep blue sea; Wulingshan also boasts its great variety of plants, most of them can leave a deep impression onto the mind of guests with their bizarre looks; here is also the home of brooks, springs, lakes and waterfalls, with the shadow of clouds and fog, the entire scene looks mysterious and vague; the water-eroded caves here are another particularity.

武陵源有许多巨大的岩石与奇怪的外观，其中一些是非常危险和steepy ：他们聚集在一起，就像许多珊瑚走出深深的蓝色海洋；武陵还拥有极大的各种植物，其中大部分是可以留下深刻印象进入到客人的离奇期待；这里也是家中布鲁克斯，泉水，湖泊，瀑布，与阴影的云和雾，整个场景看起来神秘和模糊；水侵蚀洞穴里的另一个特殊性。

The United States, for example, in Arizona, Colorado canyon remain rocks formed by station, erosion of many GuFeng, stelae, cave clusters, modelling such vivid peculiar landscape, attracts tourists from all over the world.

例如，美国亚里桑那州的科罗拉多大峡谷，基本保持了岩石经过风华、侵蚀后形成的许多孤峰、石柱、洞穴等千姿百态、造型生动的奇特景观，吸引了来自世界各地的大量游客。

This isothermal line can be regarded as the final decision line to termine the corrosion inside the blast furnace bottom.

用有限元方法计算了宝钢三号高炉炉缸、炉底的二维稳态传热过程，得到了该高炉的1 150℃等温线，该等温线可以看作高炉炉底的侵蚀终止判定线。

Effects of temperatures on thaumasite formation were investigated.

硫酸盐侵蚀是影响混凝土耐久性的重要因素之一。

Results show that paste containing ground limestone can be destroyed at the temperature of 0-10℃ by the sulphate attack of thaumasite form.

结果表明：掺石灰石粉的水泥石在0-10℃的温度范围内，可形成碳硫硅钙石的硫酸盐侵蚀破坏。

The physical and chemistry simulation on TSA process was established, and the mechanism of thaumasite formation was taken on further discussion.

摘 要：研究水泥砂浆试件在碳硫硅酸钙型硫酸盐侵蚀过程中的物理化学性能变化，对TSA过程进行模拟，进一步探讨碳硫硅酸钙的形成机理。

This proves that concrete can produce thaumasite in a sulfate environment over 15 ℃, and the existence of Mg2+ can accelerate the formation of thaumasite.

证明水泥混凝土在＞15 ℃的硫酸盐侵蚀环境下亦可生成碳硫硅酸钙，而Mg2+的存在对碳硫硅酸钙的形成过程具有加速催化作用。

Cement concrete may undergo the thaumasite form of sulfate attack when it is exposed to low temperature, high humidity, sulfate, carbonate and adequate water for a long period of time.

TSA侵蚀是水泥混凝土在低温、高湿、硫酸盐与碳酸盐长期作用下发生的一种特殊的硫酸盐侵性形式。

Limestone filler mortar suffers a typical thaumasite form of sulfate attack and its strength loss is more than pure cement mortar.

矿物掺合料的加入降低了水泥石中CH晶体含量，从而在一定程度上提高了水泥砂浆的抗TSA侵蚀能力。

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。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
