熔岩钻

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。

A 1973 Los Alamos study entitled Systems and Cost Analysis for a Nuclear Subterrene Tunneling Machine: A Preliminary Study, concluded that nuclear subterrene tunneling machines would be very cost effective, compared to conventional TBMs.

1973年，在美国洛斯阿拉莫斯，有一份书名为《对于一种核子熔岩钻隧道挖掘机的系统和成本分析：一项初步研究》的研究，得出的结论是，核子熔岩钻隧道挖掘机，相比于传统的隧道掘进机，是非常有成本效益的。

The United States Atomic Energy Commission and the United States Energy Research and Development Administration took out Patents in the 1970s for nuclear subterrenes.

20世纪70年代，美国原子能委员会和美国能源研究与开发管理部门拿出了核子熔岩钻的专利。1972年的第一个专利去了美国原子能委员会。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
