熔岩

In 1975 the National Science Foundation commissioned another cost analysis of the nuclear subterrene.

1975年，美国国家科学基金会委任了另一个核子熔岩钻的成本分析。

Whether or not nuclear subterrene tunneling machines have been used, or are being used, for subterranean tunneling is a question I cannot presently answer.

核子熔岩钻隧道掘进机是否已经被用于，或正在被用于为地下隧道挖掘是个问号，我目前无法回答。

In this way the nuclear subterrene slices through the rock like a nuclear powered, 2,000 degree Fahrenheit (1,100 Celsius) earthworm, boring its way deep underground.

用这种方法，核子熔岩钻切割穿过岩石，就像一个核动力的、2000华氏度(摄氏1100度)的蚯蚓，在向地下深处钻孔。

The nuclear subterrene has an advantage over mechanical TBMs in that it produces no muck that must be disposed of by conveyors, trains, trucks, etc.

核子熔岩钻较一般的隧道掘进机有一大优势，就是它不产生碎矿/碎石，要不还要用输送带、火车、卡车、等等来处理。

The nuclear subterrene (rhymes with 'submarine') was designed at the Los Alamos National Laboratory, in New Mexico.

核子熔岩钻(subterrene；与&submarine水下的&相谐音)被设计安置在新墨西哥州的洛斯阿拉莫斯国家实验室。

Over one hundred sixty volcanic cones,pyroclastic sheet,river valley lava and eight maars with phreatomagmatic eruption genesis distribute of Longgang volcano,Jilin Province.The volcanic rock of Longgang volcano is trachybasalt with very similar chemical composition(SiO2=48-50%).

龙岗火山区分布160多个玄武质火山渣锥，以及火山碎屑席、河谷熔岩和8个射气岩浆喷发的低平火山口－龙湾，所有火山岩为单一钾质粗面玄武岩(SiO2变化于48-50%)。

The scientists examined the lava from 18 explosions of Mount Unzen that took place during many thousands of years.

科学家们检测了熔岩从18爆炸发生在山的Unzen数千年了。

A unusual mineralizing types, native copper aggregate associated closely with asphalt and organic carbon, were discovered in tuff and the vesiculate lava at the top and bottom of the.

过去已知在峨眉山玄武岩顶部气孔状熔岩中含有杏仁状自然铜，但很少构成连续的铜矿体。

Dr Whiteside found the ratio yawed around like a drunken sailor as the continents split apart and the lava started pouring out.

怀特塞德博士发现在大陆断裂、熔岩开始喷发时，同位素的比率就如醉酒的水手一般摇晃不定。

On the third evening a stream of lava began to boil up from the centre of the volcano.

在第三天晚上，一大股熔岩从火山中奔腾涌出。

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。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
