Radial basis function coupled with a polynomial basis function was used as a trail function, and a Heaviside function was used as a test function of the weighted residual method.

这种无网格方法采用径向基函数耦合多项式基函数来近似试函数，采用Heaviside函数作为加权残值法中的权函数。

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

Trace element exhibits enrichment of LREE and antipathic elements. Trace element spidergram of obvious right deviation and extremely high containing of Sr, Zr and Hf are different from the negative anomaly of dunite which lies the bottom of ophiolite, but has weak positive anomaly.

微量元素显示LREE和不相容元素的富集，右倾的微量元素分布模式，异常高的Sr含量，Zr、Hf不同于蛇绿岩底部纯橄榄岩的负异常，而显示出微弱正异常，这些特征都与经典蛇绿岩层序底部的地幔橄榄岩不同。

Hydride generation atomic absorption spectrometry, phosphate rock, wet-process phosphoric acid, trace arsenic, trace mercury, determination

With the development of science and technology, sensitive, rapid, reproducible, simple and accurate analytical methods are required for the determination of trace elements in geological, biological and environmental samples. The direct determination of extremely low concentration of trace element with modern atomic spectroscopic method, such as atomic absorption spectrometry is so difficult. On one hand, the limitations are associated not only with the insufficient sensitivity of these techniques but also with matrix interference.

随着科学技术技术的发展，在进行地质、环境、生物等样品中痕量金属元素的测定时，常常要求达到ppb级的水平，虽然火焰原子吸收分光光度法具有很高的灵敏度，但是要直接测定这些样品中的痕量组分却很难，这是因为，一方面，样品本身的物理化学状态有的不适合直接测定，或组分的含量低于分析方法的灵敏度；另一方面是存在基体干扰。

Therefore, by configuring appropriate filters, we can bifurcate different event data to go to different sinks, something that the trace class and trace listeners definitely lacked.

因此，通过配置适当的过滤器，我们可以分叉不同的事件数据到不同的接收器，这是历史类的跟踪和追查听众绝对没有。"/页"

利用Ti对溴酸钾氧化酸性品红的抑制作用，建立了动力学光度法测定痕量Ti的新方法。

You can trace the outlines of such patterns, you know how to move your head to get a better view, and you know when you have moved it too far to see the whole keyboard. You can obscure any feature of the keyboard by holding your finger at an appropriate location between it and your eye. And instead of describing the relation between the Intel logo and the 'P' key, you can use your finger to trace a connecting path.

你能循迹这样的样式，知道如何移动你的头获得更好的视角，你知道当你移动足够员能够看到全部键盘的时候，你能在它和你的眼睛之间，用手指分不清任何键盘的特征，取代在'图标'和'P键'之间关系的描述，你能用你的手指循迹一个相关路径。
