Carbon nanotubes after oxidation and purification were used to pack a micro-column which was incorporated into a sequential injection system for facilitating online selective sorption of lysozyme from egg-white. The retained protein was afterwards quantitatively eluted by a carbonate buffer. With a sample loading volume of 2.0 mL, an enrichment factor of 12 was obtained, along with a retention efficiency of 100% and a recovery rate of 100%.

According to the results of the former study in our laboratory, trans-1, 2-cyclohexanediol is produced with a lot of acids and water, for extraction of trans-1, 2-cyclohexanediol from the solution, ethyl acetate and butyl acetate were used as extraction reagents, the solubility data of the trans-1, 2-cyclohexanediol in corresponding mixed solvents of some sorts of acetates and water are needed.

根据本实验室前期研究结果可知，反式-1，2-环己二醇是在酸性和大量水存在的条件下得到的，为了把反式-1，2-环己二醇从反应液中萃取出来，本工艺所采用的萃取剂是乙酸乙酯和乙酸丁酯，需要获得反式-1，2-环己二醇在这些酯类与水混合溶剂中的溶解度数据，因而对反式-1，2-环己二醇进行相关固液相平衡的研究是非常迫切和必要的。

It includes a set of baggies that cover the claws, preventing them from getting messed up in the process and also provides a convenient way to transport the materials until you can find a garbage can to dispose of them.

这款抓取器还包括一条包裹爪子的袋状物，它主要是用来在抓取过程中防止那东东乱成一团，同时也方便你运输这些&物质&，直到你找到垃圾箱处理掉它们。

He wanted to sae the whole world, so he went to India and tried to get scriptures. He hoped they would do good to the people. All deils were impressed by his spirit. Heaen Emperor saw that. He gae the monkey a chance to reie. He planned the master and the disciple to meet here. Then they can finish the journey to the west. Now, you know why there are so many deils here.

菩提老祖：唐三藏当年为了普渡众生不怕千辛万苦去取西经，就是为了借此经书感化世人，满天神佛都被他这种精神所感动，因此如来佛祖给了唐三藏一次五百年后重生的机会，好让他徒弟孙悟空保护他再取西经，为什么那么多妖怪在这儿出现你明白了。

Experimental results indicated that the contaminants generally existed in mussel, such as α-HCH,β-HCH,γ-HCH,δ-HCH, o·p-DDT, p·p-DDT, p·p-DDD, were degraded completely under the above conditions, whereas DDE, aldrin and dieldrin were partly degraded. No detectable degradation of PCB 1242 and PCB 1248 were observed. Thus the conventional preparation of the contaminants using the columns packed with Florisil or SiO〓 could be left out.

测定贻贝中的PCBs时，以KOH甲醇溶液处理试样，在微波能作用下，试样的微波皂化与有机氯农药的微波碱解同时进行；测定土壤和沉积物中的PCBs时，以KOH甲醇溶液处理试样，在微波能作用下，PCBs的微波萃取与有机氯农药的微波碱解同时进行，1M KOH甲醇溶液对PCBs的微波萃取能力与纯甲醇溶剂相当。

The different adsorbed species such as sulfates sulfites and adsorbed sulfur dioxides under various temperature, pressure and evacuated treatment conditions were characterized by in situ-IR. In the absent of oxygen, two bands were observed at 1050cm〓 and 1330cm〓, the former is the weakly chemisorbed sulfur dioxide species and the latter is the strongly chemisorbed SO〓.

首次利用正电子淹没技术求取了CeO〓在MgAl〓O〓上单层分布的阈值为0.075g／gMgAl〓O〓，此值略小于利用XRD法求取的单层分布阈值0.08g／gMgAl〓O〓，并且发现催化剂的氧化吸硫活性，O-Ps的生成率与CeO〓的负载量之间良好的对应关系，当CeO〓在MgAl〓O〓上形成单层分布时，O-Ps的生成率最小，此时，催化剂的活性最优。

Silk is dyed with nine reactive dyes containing various reactive systems and having different reactive groups. After the dyeings being thoroughly extracted to remove all noncovalently bounded dyes,they are treated with buffer solutions in pH range from 1.89-10.65 at 70℃.

丝用九个含有不同活性基团和活性基个数的活性染料染色，着色丝上非共价结合的染料被萃取净后，用pH值从1.89至10.65五个不同缓冲溶液于70℃进行水解，吸附在丝上的水解染料再次被萃取净。

The 2, 4 mg tubes and the control tubes were not precipitated except for the 8 mg tube with 10000 r/min configuration. The 3 transparent tubes were desalted with column of Sephadex G-25 Superfine HiTrap respectively. All of the eluents of the 3 tubes were half-diluted consecutively with phosphate buffer saline respectively to change totally into 36 samples of 2 mg group, 4 mg group and control group, with 12 in each group.
