The authors carried many researches of the feasibility about enriching and separating trace zinc from almost cadmium, and the rate of recoveries of several common metal ions according to this methodo Through repeatedly probed and tried out, at last, a thought as collaborated with traditional methods was established - using diantipyrinylmethane as complex reagent ,with ammonium thiocyanate and zinc forming the triple ionic compound in the medium of hydrochloric acid , extracted by trichloromethane, extracted the organic system by ammonium hydroxide in order to gain zinc .

本文主要研究了从镉基体中富集分离微量锌的可行性，以及采用该方法几种常见金属离子的回收率。通过反复的摸索、试验，最终确立了与传统方法相结合的思路—采用二安替比林甲烷作为络合剂和硫氰酸铵、锌在盐酸介质中形成三元离子缔合物，用三氯甲烷作为萃取剂，最后用氨水作为反萃剂将有机相中的锌洗脱出来与镉分离。

Methods Male NIH rats were treated with water containing 0.1% lead acetatic trihydrate for establishing an experimental lead poisoning rats model. QQL health liquid was administrated to rats through every day. Thirty days later, rats were killed, then the concentration of lead in blood, liver and femur were determined.

取小鼠，饮水给予0.1%三水合乙酸铅水溶液建立小鼠预防性铅中毒模型，同时灌胃给予不同浓度的受试物，喂养30天后测定血、肝脏和股骨中的铅含量。

Remember, the alcohol is taking the contents out of suspension—undissolving them, as it were—so we can actually see much of the content.

记住，酒精是将物质由悬浮物中萃取出来，不是将物质溶解，所以我们可以实地看出它的含量。

In this study, We used longer DD primers in combination with a two-step PCR protocol to overcome these two problems in term of modified methods of Martin and Pardee.K562 erythroleukemia cell differentiation induced by HEMIN or PMA for 36 hours was used as erythriod or megakaryocytic differentiation model in vitro.Total RNAs were extracted from induced and uninduced K562 cells and were applied to mRNA differential display analysis.

为解决此问题，我们参照Martin和Pardee的改进方案［3］，建立了一种使用长引物，进行二步PCR的改进DDRT-PCR方法，以氯高铁血红素和肉豆蔻佛波酯诱导K562细胞36小时作为体外红细胞和巨核细胞分化模型，取诱导前后的细胞总RNA进行mRNA差异显示分析。

It is also the main factors to control the abundances of noncrystal phase. The typical feature is that the elemental concentrations in this speciation and the percentages of this speciation in samples have significantly variation down the core, especially there is a sharp change at the depth of 80cm.

3铁锰氧化物结合态是除残渣态外的又一元素主要赋存形态，是控制元素在非晶质结合态中赋存的主要因素，同时也是岩芯不同深度沉积物中元素含量和萃取比例变化最大的一个相态。

Subsequently, the possible adducts formed in the interacting reaction were then isolated and purified.

其次，两者在交互作用中可能产生的反应加成物，也经一系列步骤加以萃取、分离并纯化。

The analytes were extracted from alkalized plasma. ion pair extracted with TBAP further purified and concentrated by SPE method, derived and detected finally by GC/MS.

在碱性环境中提取血浆样品中积雪酸，高氯酸四丁基铵与之形成离子对缔合物，经固相萃取、净化、衍生，采用内标法进行GC/MS检测。

As an indispensable converter of the paradox in life and art, Gao Yang not only boldly deletes and changes his characters' figures and sometimes even cruelly amputates or cuts off their limbs in his plane works but also brands them with his own unique media and artistic techniques.

作为生命与艺术双重矛盾的必然转换物，高炀的平面作品不仅在取材上对人物形象进行大胆的删取以至几近&残忍&地截肢、切割，而且在选用的媒介和技巧手法上也深深地被打上烙印。

The MMY biodegrading culture medium of the Lbrevis has been cultured for 10 hours,then was extracted by aceticethanol and analyzed by Mass spectra,me analytical results indicated there is new mass produced about bigger 74D than the o-Nitrophenol.

培养10h后的培养液经重蒸乙酸乙酯革取后，用质谱分析表明，新产生的中间代谢产物比底物分子量约大74D。

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。
