四重

So the little impudent fellow would waste many an ear in a forenoon; till at last, seizing some longer and plumper one,considerably bigger than himself, and skilfully balancing it, he would set out with it to the woods, like a tiger with a buffalo, by the same zig-zag course and frequent pauses, scratching along with it as if it were too heavy for him and falling all the while, making its fall a diagonal between a perpendicular and horizontal, being determined to put it through at any rate;—— a singularly frivolous and whimsical fellow;—— and so he would get off with it to where he lived, perhaps carry it to the top of a pine tree forty or fifty rods distant, and I would afterwards find the cobs strewn about the woods in various directions.

就是这样，这个唐突的家伙一个上午就糟蹋了好些玉米穗；直到最后，它攫起了最长最大的一支，比它自己还大得多，很灵巧地背了就走，回森林去，好像一只老虎背了一只水牛，却还是弯弯曲曲地走，走走又停停，辛辛苦苦前进，好像那玉米穗太重，老是掉落，它让王米穗处在介乎垂直线与地平线之间的对角线状态，决心要把它拿到目的地去；——一个少见的这样轻桃而三心二意的家伙；——这样它把玉米穗带到它住的地方，也许是四五十杆之外的一棵松树的顶上去了，事后我总可以看见，那穗轴被乱掷在森林各处。

In this study, the variable region genes of three stem McAb 1A〓-D〓, 2F〓-B〓 and 2E〓-E〓 against metal-bound tetrapeptide were joined into a single chain antibody with a linker respectively. And insert 39bp fragment of N-terminal CGRP to C-terminal of heavy chain and constitute V〓linker-V〓-CGRP single chain genes.

为获得有催化活性的抗体酶，本文将〓和〓〓三株金属螯合四肽单抗的轻、重链可变区基因，通过linker分别连接成单链基因，并在其后插入编码CGRP的N端十三肽的39bp基因片段，组成〓-linke-〓-CGRP，将该基因克隆入分泌表达载体pTC01中，获得表达产物。

A new technology for making chromium trioxide and potassium nitrate simultaneously by using nitric acid to decompose potassium dichromate has been analyzed according to phase diagrams of the K2Cr2O7-CrO3-KNO3-HNO3-H2O quaternary system at 0oC, 25oC and 45oC based on experimental results.

以实验测得的K2Cr2O7-CrO3-KNO3-HNO3-H2O四元体系相图为依据，对用硝酸酸化重铬酸钾联产铬酸酐和硝酸钾工艺过程进行分析，确定了铬和钾利用率最大时的操作条件。

The fourth was astounding.I saw a woman disguised in her maid's clothes hear her husband speak the first tender words he's offered her in years.Simply because he thinks she is someone else.I heard the music of true forgiveness filling the theater conferring on all who sat there, perfect absolution.God was singing through this little man to all the world.Unstoppable.

那段二重唱是很美丽，但我还是喜欢第四幕里gente，gente， all'armi， all'armi那一段，那是我在米洛斯福尔曼的传记电影莫扎特里感染到的，在最后一幕里费加罗的未婚妻装扮成女仆然后她的未婚夫-当然就是费加罗当着她的面在说他有多么的爱他的未婚妻，因为他重来没有尝试这表达，而他今天表达的只应为他并不知道女仆就是她的未婚妻。

The efficacy of photocatalytic oxidation was relative to the number of dip-coated plate, which 2 and above plates was superior to one plate, and also vertical plane to the light source was more efficient than parallel plane. The reaction rate constant showed the color removal decreased as initial MB concentration was raised. As for efficiency of catalyst durability, it was found that TiO2 dip-coated stainless steel plate performed 95% color removal at 5ppm MB even after 4 times repeated usage, which showed favorable durability. However, when the concentration up to 10 ppm, the color removal decreased as the used counts was raised.

脱色率和钢网片数有关，钢网片数超过2片以上时，其光催化效能优於单片者；光催化效能与钢网摆放方式或光源入射的角度有关，与光源垂直摆放的脱色率优於与光源平行摆放者；由反应速率常数得知，反应物之脱色率随著反应物初始浓度的提升而递减：在耐用性方面，亚甲基蓝5ppm在重覆使用四次后，其六个小时脱色率皆维持95%，显示自制光触媒钢网之耐用性颇佳，若将反应物浓度提升至100ppm，其脱色率随著使用次数之增加而递减。
