变质

Adverse forecasting factor includes that of adverse structure, adverse magmatic rock, adverse lithofacies paleogeography and adverse metamorphism.

不利预测因素包括不利的构造因素、不利的岩浆岩因素和不利的岩相古地理因素以及不利的变质作用。

It can therefore, be deduced that the protolith from which sapphirine was derived is not necessarily magnesiorich pelite.

含假蓝宝石的变质岩石之原岩未必是富镁泥质岩。

The protolith of northern khondalite series in neighbouring region is a suite of flyschoid formation consisting of argillaceous arkose-pelitic feldspathic greywaske with intercalations of pelite, silt as well as carbonate and marl beds. They were deposited on continental margin under relative stable tectonic enviroment.

所有特征表明二者之间不存在有些研究者所认为的不整合接触关系，而是大量奥长花岗质-英云闪长质和一些中基性岩浆顺层侵入到一套沉积和火山-沉积表壳岩中，并一起经受多期复杂的变质和变形作用所成。

Genetic mechanism of metamorphic peridotite in the ophiolites is partial melting of the upper mantle peridotite. Difference between two types ophiolites is dicided by degree of the partial melting.

两类蛇绿岩中变质橄榄岩的成因机制是上地幔岩部分熔融，两者之间的差异则是由部分熔融程度决定的。

This paper gives a brief review of the characteristics and petrogenesis of mantle peridotite in continental subduction and collision belts, and then discusses in more detail the petrogenesis of peridotites in the North Qaidam ultrahigh pressure metamorphic belt.

论述了大陆俯冲碰撞带中地幔橄榄岩的基本特征和成岩类型，并重点讨论柴北缘超高压变质带中不同性质的橄榄岩及其成因。

For perilla oil contains high proportion of unsaturated fatty acid such as α-linolenic acid,it is very easy to deteriorate.

紫苏油含有大量的不饱和脂肪酸，是迄今发现的α-亚麻酸含量最高的植物油，极具药用价值和保健功效，但也极易氧化变质。

Products with the greatest potential for regular air movement are those having high value or extreme perishability.

高价值或易腐变质产品最有可能成为定期空运的产品。

Because our pet food is perishable, it is important to protect it from the Big Three

由于宠物粮是容易变质的，因此规避以下三大影响因素是很重要的

A given tectonic force may be resolved into two parts: homogeneous stress and differential stress. Homogeneous stress refers to isotopic pressure,which is superimposed on the original pressure and affects the equilibrium of various chemical reactions. It is also a factor that influences petrogenesis,metallogenesis and metamorphism.

构造力可以分解为两部分一部分是均应力，指各向相等的应力，它叠加在原有压力之上，并且影响着各种化学反应的平衡，也是成岩、成矿和变质作用的影响因素。

The fluid inclusions in several types of rocks in the Dabie UHP zone were systematically investigated in the aspects of petrography and temperature of phase change.

对大别超高压变质带主要构造单元各类地质体岩石中的流体包裹体进行了岩相学和相变温度的观察与测定。

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％。
