熔岩

With the different distances between fissures and Laoheishan volcanic cone and the types of lava flows (sheet lava flows or small sub-overflows), the tension fissures show the different features.

随着距离老黑山火山锥位置的不同和熔岩流的类型(如席状熔岩流、小规模次级溢流体)不同，张裂呈现不同的特征。

White volcanic gases escape from the vent and erupting lava, while a steam plume rises where the hot lava meets snow.

白火山气体逃离发泄和喷发熔岩，而蒸汽柱在上升的热熔岩会见雪。

Andesitic lava flows also occur within the caldera, and are overlain by a chaotic complex of silicic lava and intracaldera pyoclastic flow deposits.

安山质熔岩流也出现在火山口，并得到了硅酸熔岩流沉积和intracaldera pyoclastic混乱复杂的覆盖。

The parental magmas of the Wudangshan Group and Yaolinghe Group basic lavas from Wudangshan area were then subjected to shallow level gabbroic (cpx+plag±ol) fractionation and the chemical evolution of the basic lavas and basic dykes from other areas was controlled by a clinopyroxene+olivine fractionation.

武当山地区的武当山群和耀岭河群基性熔岩的母岩浆经受了浅层位辉长岩质(cpx+plag±ol)分离作用，而其他地区基性熔岩和基性岩墙的化学演化则是受控于单斜辉石±橄榄石分离作用。

The chemical evolution of the LT1, LT2 (in central Tianshan and Baishan of Gansu), LT4 (in western Tianshan, Jungar and Baishan of Xinjiang) and LT3, HT lavas is controlled by an olivine + clinopyroxene fractionation, but gabbroic fractionation accounts for the chemical variation of the LT4 lavas from eastern Tianshan.

LT1、LT2、LT4（天山西段、新疆北山和准噶尔）和LT3、HT熔岩的化学演化系受控于橄榄石+单斜辉石结晶分离作用；而天山东段的的LT4熔岩的化学变异则是经受了辉长岩质结晶分离作用。

A hornito develops when lava is forced up through an opening in the cooled surface of a flow and then accumulates around the opening.

当熔岩通过已经冷凝的表面之开口被迫向上挤出时，就在开口周围堆积形成熔岩丘。

Hornito is a Spanish term meaning "little oven," and small lava cones like this one from Hawaii resemble old-fashioned outdoor wood-fired ovens.

翻译成中文为：Hornito是西班牙语，意思是&小火炉&，是小型的熔岩锥，在夏威夷的熔岩丘像老式的户外燃木火炉。

The author has paid attention to the two kinds of lavas which locate the south-east end of the Kalamaili belt. Through the field investigate and the geochemistry experiment the author has contrasted the two kinds of lavas in the ophiolitic melange, made clear the tectonic background and summarized the geochemical characteristic and then discussed the formed environment and tectonic significance.

作者以该蛇绿混杂岩中的两类中基性火山熔岩为研究对象，通过野外实际观察和室内地球化学实验分析，将这两类火山熔岩进行对比研究，弄清其大地构造背景，总结其地球化学特征，并由此探讨该蛇绿混杂岩的形成环境及其构造学意义。

We can see copper-bearing asphalt amygdaloidales in the basalt lava and stockwork of native copper in the carbon-rich tuff. There area so much carbon in the ores that people only can see the native copper aggregate after splitting and polishing the ores.

最近，在该熔岩层上下的凝灰岩中鉴别出难识别矿化类型，即与沥青和有机质碳紧密伴生的富铜矿石，甚至在气孔状熔岩中发现呈杏仁体含铜沥青，因而可能构成大规模矿化。

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。

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％。
