Useful life assessment for a type of turbojet engine.

某型涡喷发动机使用寿命的评定方法。

In addition, the change of main operating parameters of the twin-spool turbojet engine was also predicted in the process of jetting-water and forcing surge.

此外，还预测了喷水逼喘过程中双轴涡喷发动机主要工作过程参数的变化。

A turbojet engine and its main fuel control system with hydro-mechanical regulator are studied. The rotational speed control system is modeled according to the analysis of the engine control program.

以某型涡喷发动机及其主燃油系统的机械液压式调节器为研究对象，在考虑其控制规律的前提下，建立了转速控制系统及其各部件的数学模型。

The way a basic Turbojet engine burns it's fuel is exactly the same as in car engine, but instead of burning the fuel in discrete packets, the jet engine continuously sucks, squeezes, bangs and blows all at the same time!

一个基本的方式涡喷发动机燃烧它的燃料是完全一样的汽车发动机，而是燃烧的哪类燃料，喷气发动机，不断吸，挤，爆炸和打击在同一时间！

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似；(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集，而配分模式的相似性反映了火山物质来源与玄武岩具有同源性；(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式，说明界线粘土岩成因也不同于煤山剖面的界线粘土；(4)大量的玄武岩岩屑；(5)Ti元素的富集；(6)亲铁元素Ni和Co含量较低，特别是在界线异常层含量降低，表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件，这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。

A fountain of lava erupts from the Mauna Ulu vent in Hawaii's Kilauea volcano.

喷泉熔岩喷发从茂乌卢发泄在夏威夷的几劳亚活火山。

Patterns in Nature: Lava A fountain of lava erupts from the Mauna Ulu vent in Hawaii's Kilauea volcano.

喷泉熔岩喷发从茂乌卢发泄在夏威夷的几劳亚活火山。

"Hawaii's Mauna Ulu spouts a fountain of molten rock. A geologist, approaching cautiously from the upwind side, records the volcano's tantrum."

意译：夏威夷的Mauna Ulu 喷发熔岩浆，一位地质学者慎重的自逆风侧接近，他记录了火山是如何发脾气的。

As volcano eruption is deemed to be an uninsurable risk, there are few studies to turn to.

因为现在认为火山爆发是不可投保的风险，所以有关火山喷发的研究甚少。

After that the territor ial extensional stress field caused by the plates movement and the mantle upheave etc. makes the Yishu fault system keep on cutting downward tend to form rift valley. The tectonism causes the fairly large-scale invasion of the small neutral -partial alkaline rock-bodies and the gold mineralization in the Linyi area.

燕山中期板块俯冲运动和地幔上涌等因素引起的区域性拉张作用使沂沭断裂继续向下深切张裂，向裂谷性质演化，造成沂南、临沂等地区较大规模中性偏碱性次火山岩型小岩体的侵入和火山喷发，在火山机构内或围绕次火山岩小岩体形成与中性偏碱性次火山岩有关的次火山岩型金矿化。

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％。
