Additionally, some trace elements in coals, which indicate the paleoclimate and the types of bog in coal-forming period, can also show hydrocarbon generating potential of coal, such as Cu which has a strong affinity to organic macromolecule in coals. Cu is a fades element, and may be an indicator element of hydrocarbon generating potential.

其中Cu既是一个有着与煤的大分子物质较强亲和力的元素，又是一个可以显示古气候古成煤沼泽类型的"指相"元素，因而在指示煤的生烃潜力方面可能具有普适性。

Tones, given the series of six generating formula, random from the series were selected as a game of this round of the series, and from the series of randomly selected to three consecutive elements, which users guess the next series is one element of what?

猜数字，给定六个数列的生成公式，随机地从上述数列中选取一个作为本轮游戏的数列，并从该数列中随机地选取连续地三个元素，请用户猜该数列的下一个元素是什么？

The main results are as follows:We review the existing Monte Carlo control variates estimators of the price of Asian options and propose a new one. According to pratical needs, we define efficiency as the inverse of the product of the variance of an estimator and its computational time and make it a standard for comparisons to draw the following conclusions: Firstly, the more control variates correlate with arithmetic average Asian options, the larger is the efficiency of an estimator with these control variates, but among which the geometric average option plays the most important role; Secondly, an estimator with more control variates is better than one with less ones only when the time to maturity is long and the volatility is high.

在综合已有研究工作的基础上，本论文的主要创新成果如下：（1）我们回顾了已有的亚洲期权价格的蒙特卡罗控制变量估计，并提出了一个新的控制变量估计，且从客观实际出发，将估计值的方差和计算时间的乘积的倒数定义为效率并以它为标准比较各估计，得到以下结论：与算术平均亚洲期权相关程度越大的控制变量构成的估计的效率越大，而其中起主要作用的控制变量为几何平均亚洲期权的价格；只有在到期时间较长且标的资产的波动率较大时，元素多的多元控制变量估计比元素少的效率大。

In addition, the colonization of Glomus mosseae also reduced N∶P ratio of clover, this can lead to the shift in limitation from P to N nutrient.

此外，在一定磷水平下，菌根真菌的存在降低了三叶草中N∶P比，这会改变三叶草的受限制方式，由受P元素限制变为受N元素限制。

What They Do - They contain magnesium which aids in fighting gloominess, misery and confused states of mind.

作用——上述物质都含有镁元素，镁元素有助于抵抗沮丧、苦恼和困惑的精神状态的发生。

From the angle of graphics, the different aesthetic sensibility of each chirog-raphy and font are also decided by their graphic character: the strokes' form and configuration, which makes it easier for us to see the close relationship between Chinese character and graphics.

从图形的角度来看，汉字的各种书体、字体之所以具有各自的感性特征，是由其构成元素--笔画造型、间架结构这些具有图形性质的元素决定的，由此我们更可看出汉字与图形的密切联系。

Developed from GNZ series of mobile suits, the chassis is reused from GN-008GNHW/B Seravee Gundam GNHW/B and shows some similar design elements of the GNZ-series of mobile suits, like the GNZ-001 GRM Gundam and GNZ-003 Gadessa, as well as some elements from the GN-002 Gundam Dynames.

拉斐尔高达从GNZ系列MS发展而来，同时重新运用了GN-008GNHW/B Seravee Gundam GNHW/B的骨架，在设计元素上与GNZ系列有相似之处，同时也采用了GN-002 Gundam Dynames的一些元素。

Effects : Finds an iterator to the first element whose key is "key" according to the given hasher and equality functor or end if that element does not exist.

作用： 找到一个迭代器，指向按给定散列函数及相等性函数其键值为"key"的第一个元素，如果该元素不存在，返回 end。

Second, men can donate blood regularly Cancer Prevention British scientists study found that men can donate blood cancer, it is because contains a lot of iron in the blood, and the body of continuing high level of iron content will be promoting cancer, regular blood donors to be effective in lowering blood-content hemosiderosis, health men can donate blood regularly received from the cancer effects.

二、男子定期献血可防癌英国科学家研究发现男子献血可以防癌，这是因为血液中含有大量铁元素，而人体内铁元素含量水平持续过高会促会癌症，定期献血可有效地降低血液中铁血素的含量，因此健康男子定期献血可收到离癌的效果。

Sc, there are two kinds of isotopes shaped body, the structure is trigonal system and the hexagonal Department, is found in the periodic table predicted decades before the first one confirmed the correctness of the periodic table of elements, which is very famous.

周期表中ⅢB族有银白色金属光泽的固体金属过渡元素，又属稀土元素，原子序数Z＝21，原子量4959，化学符F号Sc，有两种同位素异形体，结构正方晶系和六角晶系，是周期表预言十年后才发现的第一个证实周期表正确性的元素，因而很有名气。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
