熔岩隧道

At Thurston Tube, thick tree ferns and ohia trees nearly engulf lava tunnels, leftovers from an ancient flow.

在瑟斯顿，厚树蕨和ohia树木几乎被熔岩吞没隧道，这是来自一个古老的流动。

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。

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。

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。

As the lava beneath pulses and flows along its channel, small gouts of it spatter up and outward, building a little pile around the opening（图版I—1）( http://geology.about.com).

当下面隧道中的熔岩流沿着隧道脉动时，小股熔岩向上向外溅落，这样熔岩就在开口周围堆叠在一起。

Hornitos form along the tops of lava tubes, wherever an opening in the solid upper crust appears.

熔岩丘在熔岩隧道之上的地表形成，凡是熔岩隧道上部固态壳有开口的地方就出现熔岩丘。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
