查询词典 trace fossil

It has unique physiological structure and some evolutionary trace so it is called the living fossil.

第三部分是中华鲟生长激素受体和生长激素结合蛋白质的鉴定。

Results: The profiles of split trace of 40 bone fossil samples respectively from Stegodon orientalis, Chinese rhinoceros, Cervus and other mammalian fauna were identified, some of them were found blunt and might be rodent bite marks.

结果 经40件东方剑齿象、中国犀、鹿等残骨化石标本断裂痕迹剖面的观测，发现有部分骨化石断裂剖面圆钝，似啮齿动物的咬痕，但大部分骨化石断端剖面呈锥形切削改造，有的双面削刮呈锐利器型，有的存在明显打击或铲刮的"印记"，初步认为属早期人类制作骨器的遗迹。

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

氢化物发生-原子吸收光谱法，磷矿石，湿法磷酸，微量砷，微量汞，测定

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"

Based on the inhibitory effect of trace Ti on the oxidation of fuchsin acid by potassium bromate,a new kinetic spectrophotometric method for the determination of trace Ti has been developed.

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。

A historical region of southwest France between the Pyrenees and the Garonne River. The duchy of Aquitaine was joined with France after the marriage of Eleanor of Aquitaine to King Louis VII in1137, but its possession was disputed after her subsequent marriage to Henry II of England.

阿基坦法国西南部一个历史地区，位于比利牛斯山和加隆河之间，在1137年阿基坦的埃莉诺与国王路易斯七世结婚之后阿基坦公国加入法国，但当她再嫁英国亨利二世后，其归属权便受到争议

There are moments when I look at the smiling , happy faces of my expectant staff and wonder how they will cope when confronted by an outraged housemaster along with an unrepentant and recalcitrant bleached blond teenager in 18 years ' time .

有时候，我看着那些满怀期待的员工微笑，幸福的脸，想着当他们遇到一位愤怒的宿舍管理员和一位不知悔改，叛逆，而且将头发染成白色的18岁少年时，他们会如何处理。
