Based on the complexity of the sources for the sediments in the Okinawa Trough, the sequential extraction procedure was applied to the hydrothermal influenced sediments in the core H9 recovered from the middle Okinawa Trough. Five fractions, including exchangeable, bound to carbonates, bound to iron and manganese oxides, bound to organic matter, and residual were acquired. Based on detailed analysis for major, minor and rare earth element compositions, the distributions of the elements in various speciations of the sediments were determined and the controlling mechanism was discussed. The variations of hydrothermal signatures in the core, partitioned from the terrigenous, volcanic and biogenic materials, have been demonstrated and the accumulation rates of some elements were evaluated.

本文针对冲绳海槽多种物源沉积作用混杂的特征，采用顺序淋滤萃取方法对海槽中部受热液活动影响的H9岩芯沉积物进行了分离，将沉积物中分为可交换态、碳酸盐结合态、铁锰氧化物结合态、有机结合态和残渣态五个部分，并对各个结合态中常量、微量和稀土元素组成进行了分析，确定了不同元素在不同结合态中分配的比例，分析了控制不同元素进入沉积物的主要机制。

When PEN and PET were melt blended, however, transesterification between two homopolymers would take place and the resultant product may be not crystallizable.

PET／PEN共混物在熔融共混时可能会发生酯交换反应，生成嵌段共聚物或无规共聚物，从而对PET／PEN共混物的结晶性能和热性能产生不利的影响。

Intercalation of metal complexes into the interlamellar space of clay is an excellent method for homogeneous catalyst heterogenization .

粘土的可膨胀的二维空间有助于将催化活性的金属络合物用阳离子交换法和配位体交换法插入到粘土层间，因而易于制得粘土层间金属络合物催化剂，这是匀相催化剂多相化的一种好方法。

At first, bartering took place as an exchange between two people.

最初的物物交换只是作为一种交换形式在两个人之间发生的。

At first, bartering took place as an exchange between two people.

过去，最早的&物物交换&是发生在2个人之间的一种交换。

Previously, anthropologists have already done lots of relevant researches about the exchange and the market, but limited systematic research on barter in market economy.

许多人类学家对交换和市场做了大量的研究，但是关于市场经济条件下的物物交换方面的系统研究则较少。

In a barter economy it would be necessary to determine how many plates were worth one hundred weight of cotton, or how many pens should be exchanged for a ton of coal, which would be a difficult and time-consuming task.

根据原文的上下文，我们可猜测出barter economy就是&物物交换经济&，由此可知正确答案为C：货物被交换，而不是用货币。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
