It is an important aspect in cause of petroleum formation that hydrocarbon from fatty acid or ester decarboxylation catalyzed by minerals at low temperature.

中文摘要：矿物低温催化脂肪酸或酯的脱羧生烃是石油成因机制的一个重要方面。

Fatty acid ; mineral catalysis ; low temperature ; decarboxylation ; detecting method ; carbon dioxide

脂肪酸；矿物催化；低温；脱羧作用；检测方法；二氧化碳

Therefore, based on these experiments, it can be deduced that the transfer ability of electron in slag phase is of great importance to decarburization reaction at low carbon level.

因而推断：在低碳含量范围内，熔渣中电子的传递能力对反应起着非常重要的作用。

In TRPL we did not observe the constant decay time even at low temperature.

测量的衰退时间常数在30K时为3.6ns，这是我们所知道的最长的衰退时间常数。

In this paper,the in- fluence of the coupling aperture on the sound energy decay and coupling constant in the primary room is investigated by means of the finite-difference time-domain method,and the investigation is limited within the low-frequency range.

文中运用时域有限差分法，在低频范围内模拟了耦合窗面积的改变对主厅中不同位置的耦合常数和声能衰减的影响。

From the junction temperature-varied optical properties measurement, we find that the luminous efficiency will decay more quickly at low current operation. However, when the current density increases to the saturation capacity of the quantum well, the decay ratio will reach a constant.

在变温的光学特性量测上，由实验结果发现，发光效率在较低电流时会衰减的较快，然而在注入电流达到量子井的饱和量后，其发光效率随接面温度升高衰减的现象则会趋近於固定的比例。

In the world, become world the biggest fruit to produce a country, but long-term since because take crop seriously, negligence quality, take measure of the increase production before collecting seriously, negligence collects an aftertreatment, store up treatment, the decay after causing fruit greens product to collect is degenerative and serious, loss is great, main show is in these problems the following respects: 1Structure of breed of product of.1 fruit greens is unreasonable although the crop of fruit greens product of our country is tall, but quality is poorer, market price is low, breed structure is unreasonable, early, medium scale of ripe, late-mature breed is undeserved, do not have especially comfortable the high grade breed at treatment, restricted our country fruit to machine the development of course of study apparently.

因此提高果蔬产品的质量，发展贮藏加工业，是我国果蔬产业发展亟待解决的问题。1 目前我国果蔬产业发展中存在的问题自 1993年以来，我国果品产量跃居世界第 1位，成为世界第一大水果生产国，但是长期以来由于重视产量，忽视质量，重视采前增产措施，忽视采后处理、贮藏加工，造成果蔬产品采后腐烂变质严重，损耗极大，这些问题主要表现在以下几个方面：1.1 果蔬产品品种结构不合理我国的果蔬产品产量虽高，但质量较差，市场售价低，品种结构不合理，早熟、中熟、晚熟品种比例不当，非凡是没有适于加工的优质品种，明显制约了我国果品加工业的发展。

This means that in emergency situations or sudden deceleration, the transmission can quickly step down to LOW gear.

这意味着在紧急情况或突然减速时变速器能够快速的降到低齿轮。

But its design takes long times and great eforts with low designing efficiency; with development of science and technology and national economy, not only the requirement of worm decelerator is in larger and larger number, but also in higher and higher quality.

但其设计过程繁琐、周期长、效率低；随着科学技术和国民经济的发展，蜗轮蜗杆减速器的需求量越来越大，且对质量提出了更高的要求，而采用传统的设计方法己远远不能够满足技术发展的需要。

The book reports that cancelling mechanic decelerator brings along the problems of low speed and high torque gearless drive system, and how to get a strategy for solving problems.

重点介绍了取消机械减速机后，给低速大转矩无齿轮传动系统带来的问题及其解决策略，并且强调电子-电气-机械一体化最优是解决策略的基本原则。

"Please accept this talisman as a token of our thanks."

请收下这个护身符以表达我们的感谢。

If I have that magic, I will be more acceptable in the society.

如果我拥有那种魔法，我将更加被这个社会所容纳。
