It is home to the world's largest consentration of geysers, such as Old Faithful Geyser, hot springs, mud pots, fumaroles, and travertine terraces.

它是世界上最大的consentration的喷泉，如老忠实喷泉，温泉，泥盆，喷气孔，和石灰梯田。

The practice of burning the mixed gas shows that the mixed combustion process favors the comprehensive utilization of surplus blast furnace gas and reduces gas consumption cost for producing lime, thus it has good economic and environmental benefits.

石灰窑燃烧混合燃气的实践表明，该混烧工艺既有利于富余高炉煤气的综合利用，又降低了生产石灰的用气成本，具有良好的经济效益、节能降耗效益、环保效益。

The gas burning lime upright stove is improved at Jigang. The cylinder form was changed as rectangular plus arcuate forms, the structure of lime discharge machine was redesigned, the air and gas heat exchangers are connected in series in dedusting flue. The rate of raw and over burning of lime is less than 7%, the breakages of tooth and shafts on lime discharge machine are decreased and gas is saved.

济钢对气烧石灰窑进行改进，将圆柱型窑形改为矩形+弓形，并重新设计了出灰机结构，在除尘烟道上串联增设了空气，煤气换热器，使石灰的生，过烧率低于7%，减少了出灰机的断齿，断轴现象，而且节约了煤气。

After reform and opening up, China's number of building materials production jumped first in the world, such as cement, glass, construction ceramics, clay, lime and so on, but at the same time their development is based on excessive energy consumption and environmental pollution for the price.

经过改革开放以来，中国的一些建筑材料生产跃升世界第一位，如水泥，玻璃，建筑陶瓷，粘土，石灰等，但同时它们的发展是基于过度的能源消耗和环境污染价格。

Longquan kiln glaze in powder blue and green plums, known use of lime alkali glaze, glazing thick, so that objects appear plump appearance, and to appear or soft elegant device surface, like a sapphire in pink green glazed color, or color appears comparable with emerald green glazed plum color, celadon glaze color and texture, they become the pinnacle of the United States.

龙泉窑釉色以粉青和梅子青著称，采用石灰碱釉，施釉较厚，使器物外观显得饱满，并使器面出现或柔和淡雅，有如青玉的粉青釉色，或出现色调可与翡翠媲美的梅子青釉色，它们成为青瓷釉色与质地美的顶峰。

The influences of the addition of ground limestone,fly ash and the mixed addition of ground limestone and fly ash on the chloride diffusivities of the high strength concrete are studied by using NT BUILD 492 method.

我国石灰石粉来源丰富，价格低廉，并已广泛用作水泥工业的混合材和混凝土的矿物掺和料。

The brick floor was inhabited by both competitive and communist insect life, despite the lime dust with which I covered the cracks.

虽然我用石灰粉填塞了砖缝，但是各种昆虫仍然栖居在那儿，有相互争斗的，也有紧紧地拥挤在一起的。

The results of the test showed that when the pH value of the wastewater was1.5,the dosage of iron filings was1%,the particle size of iron filing was60mesh,and the reaction time was40minutes,the removal rat...

目前在国内经济发达地区如苏南，都是直接用石灰中和来除去金属离子，其结果会产生大量的含铜含铝废渣

The traditional approach to supplementing P for plants is to apply P fertilizer to the soil, but most of it may be readily immobilized or fixed by calcium ions in the lime soil or by iron and aluminum hydroxide in the acid soil, which results in a low use efficiency of P applied.

改善植物磷营养的传统方法是对土壤增施磷肥，但大部分磷肥被石灰性土壤中的钙和酸性土壤中的铁、铝氢氧化物固定成为无效态在土壤中积累起来。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
