查询词典 crude

That crude oil and natural gas lie in petroliferous basins is related to the basinal basement crust's insulation which allows the preservation of volatile compositions in asthenosphere of upper mantle bulge and the full geochemical actions.

石油及天然气储存在含油气盆地之中是与盆地基底地壳的特性有关，它的隔热性保证了地幔隆起上部软流层中挥发组分的保存和充分的地球化学作用。

The need of crude oil and its products increase day by day at the present time.

本课题旨在通过一种新的方法来研究微生物降解石油废水。

A novel method was proposed for the direct determination of biomarkers,such as n-alkanes,terpanes and steranes in crude oil by GC/MS coupling with backflush cutting technique and micro-fluidic splitter.

Save the solvent: Only need to join 5-6 times of solvents of crude drugs quantity once, utilize new solvent conduct of hot backset

溶剂节省：只需一次加入药材量的6-8倍溶剂、利用热回流的热冷凝液新溶剂作为补充，可使药材的投放量成倍增加。

High drawing rate:Because the constant supplement of solvent of the hot backset current, make crude drugs and sllvent remain

提取率高：由于热回流的新溶剂不断的补充，使药材与溶剂始终保持较高浓度梯度，加快了药材有效成份的溶出，提取较为安全。

According to practical experience and study for many years, hot condensation liquid of backset current invite within 2.5-3 hours drawing former solvent of pot all change once, can keep a higher density to the draw pot crude drugs in unit time.

回流的热冷凝液约在2.5-3小时内将提取罐原溶剂全部更换一次，使提取罐内中药材组成中溶质浸出液中的溶质在单位时间能保持一个较高的浓度差，既继承了传统提取罐二次提法的工艺，又节省了50％溶剂投放量。

In fact, crude began its most recent backwardation in August 2007 at around $75/barrel and increased dramatically over the next nine months to $133/barrel at contango levels.

事实上，原油价格在2007年8月每桶75美元的时候开始其最近一次的现货溢价，随后油价在接下来的9个月内暴涨至每桶133美元的期货溢价水平。

In 2005, the discussion was focused on the distorting effect the rapid inflow of money tracking commodity indices were having on the crude oil forward curve, which had flipped from backwardation to contango.

在2005年，跟踪初级产品价格指数的资金迅速流入市场，使得原油价格由现货升水状态转变为期货升水状态。这些资金对原油远期价格曲线的干扰效应就成了当时讨论的焦点。

Exploitations and prospects of natural lotus leaf bacteriostat were discussed.The main results were as follows:1、The extraction rates of crude extract, flavonoids, alkaloids and volatile oils from lotus leaves were high, and they had strong inhibition on bacteria activities but no distinct inhibition on yeast and mold.

主要研究结果如下：1、荷叶粗提物以及荷叶中的主要功能性成分黄酮、生物碱和挥发油都具有较高的提取得率，对所有供试细菌有较强的抑制作用，对霉菌和酵母菌的抑制作用相对较弱。
