In addition concentrated QC can also inhibit the growth of skin tumor caused by shope papilloma virus. But neither concentrated QC, nor D77 could inhibit the mouse skin tumors caused by chemical carcinogen and tumor promoter with initiation and promotion protocol.

另外中药QC膏剂还可抑制Sh〓乳头瘤病毒所致的兔乳头瘤；D〓腹腔注射时对S-180腹水瘤也有一定的抑制作用；但无论是中药QC膏剂，或D〓对化学致癌物3-甲基胆蒽与促癌物巴豆油合用诱生的小鼠皮肤瘤无抑制作用。

After the acidizing, the core was clean and there were no retentions.

酸化后岩心清洁，无任何滞留物。

We didn't cook none of the pies in the wash-pan -- afraid the solder would melt; but Uncle Silas he had a noble brass warming-pan which he thought considerable of, because it belonged to one of his ancesters with a long wooden handle that come over from England with William the Conqueror in the Mayflower or one of them early ships and was hid away up garret with a lot of other old pots and things that was valuable, not on account of being any account, because they warn't, but on account of them being relicts, you know, and we snaked her out, private, and took her down there, but she failed on the first pies, because we didn't know how, but she come up smiling on the last one.

我们并没有在洗衣盆里烘饼，深怕盆的焊锡见火会化。西拉斯姨父有一把珍贵的铜暖炉，是他珍爱之物，因为这有木头长把子的炉，是他的一个祖先随着征服者威廉坐&五月花&之类早先的船只从英格兰带来的，他一直把它和其它珍贵的古物藏在顶楼上。珍藏的原因倒不是因为有什么价值，它们并无什么价值，但却是因为这些是古董。我们把它偷偷弄了出来，带到下边的树林子里。烘开头几次馅饼时失败了，因为我们开头不得法，不过最后还是成功了。

Although many researchers have studied the synthesis of allyl phenyl ether by phase-transfer catalysis, no studies have used it in membrane reactor up to now. The purpose of this paper is to combine the studies of membrane reactor and phase-transfer catalysis. The membrane was used to stabilize the aqueous/organic interface at a fixed position, also the quaternary ammonium ion in the membrane was used as the catalyst to partake in the reaction system directly, and so it can also separate the product and reactants at the same time. A theoretical model is also presented.

中文摘要对於利用相间转移触媒催化技术来合成丙烯基苯基醚的反应，已有不少专家学者研究过，而至今还无在薄膜反应器中进行此反应之研究，本研究则是要结合薄膜反应器与相间转移触媒两者之特性，固定水油两相之界面，并且利用薄膜上的四级铵离子为触媒，直接在反应系统中参与反应，并同时分离产物及反应物，进而推导出相关之理论模型。

A detailed analysis of the experimental results implied that the attractive forces play a main role in the collisional quenching processes of NCO by the quenchers studied in this work, and for some quenchers, the quenching of NCO is probably controlled by the entrance-channel and might be ascribed to the contribution of chemical reactions.

这一加成过程是一个入口势能面属于纯吸引型的无垒过程，故是NCO+O反应的主要通道。二是O原子攻击NCO分子的O原子得到中间物tran-NCOO，再通过C-O键的断裂生成产物CN+OO。该产物通道由于是吸热的，故很难发生。

I sometimes dream of a larger and more populous house, standing in a golden age, of enduring materials, and without gingerbread work, which shall still consist of only one room, a vast, rude,substantial, primitive hall, without ceiling or plastering, with bare rafters and purlins supporting a sort of lower heaven over one's head —— useful to keep off rain and snow, where the king and queen posts stand out to receive your homage, when you have done reverence to the prostrate Saturn of an older dynasty on stepping over the sill; a cavernous house, wherein you must reach up a torch upon a pole to see the roof; where some may live in the fireplace,some in the recess of a window, and some on settles, some at one end of the hall, some at another, and some aloft on rafters with the spiders, if they choose; a house which you have got into when you have opened the outside door, and the ceremony is over; where the weary traveller may wash, and eat, and converse, and sleep, without further journey; such a shelter as you would be glad to reach in a tempestuous night, containing all the essentials of a house, and nothing for house-keeping; where you can see all the treasures of the house at one view, and everything hangs upon its peg, that a man should use; at once kitchen, pantry, parlor, chamber, storehouse,and garret; where you can see so necessary a thing, as a barrel or a ladder, so convenient a thing as a cupboard, and hear the pot boil,and pay your respects to the fire that cooks your dinner, and the oven that bakes your bread, and the necessary furniture and utensils are the chief ornaments; where the washing is not put out, nor the fire, nor the mistress, and perhaps you are sometimes requested to move from off the trap-door, when the cook would descend into the cellar, and so learn whether the ground is solid or hollow beneath you without stamping.

我有时梦见了一座较大的容得很多人的房屋，矗立在神话中的黄金时代中，材料耐用持久，屋顶上也没有华而不实的装饰，可是它只包括一个房间，一个阔大、简朴、实用而具有原始风味的厅堂，没有天花板没有灰浆，只有光光的椽木和桁条，支撑着头顶上的较低的天，——却尽足以抵御雨雪了，在那里，在你进门向一个古代的俯卧的农神致敬之后，你看到衍架中柱和双柱架在接受你的致敬；一个空洞洞的房间，你必须把火炬装在一根长竿顶端方能看到屋顶，而在那里，有人可以住在炉边，有人可以往在窗口凹处，有人在高背长椅上，有人在大厅一端，有人在另一端，有人，如果他们中意，可以和蜘蛛一起住在椽木上：这屋子，你一打开大门就到了里边，不必再拘泥形迹；在那里，疲倦的旅客可以洗尘、吃喝、谈天、睡觉，不须继续旅行，正是在暴风雨之夜你愿意到达的一间房屋，一切应有尽有，又无管理家务之烦；在那里，你一眼可以望尽屋中一切财富，而凡是人所需要的都挂在木钉上；同时是厨房，伙食房，客厅，卧室，栈房和阁楼；在那里你可以看见木桶和梯子之类的有用的东西和碗橱之类的便利的设备，你听到壶里的水沸腾了，你能向煮你的饭菜的火焰和焙你的面包的炉子致敬，而必需的家具与用具是主要的装饰品；在那里，洗涤物不必晒在外面，炉火不熄，女主人也不会生气，也许有时要你移动一下，让厨子从地板门里走下地窖去，而你不用蹬脚就可以知道你的脚下是虚是实。

A fourth pit at the tomb was apparently left empty by its builders, while Qin Shihuang's actual burial chamber at the center of the complex has yet to be excavated.

当初建陵墓者显然刻意让第四号坑内空无一物，位於秦陵中央真正的秦始皇陵寝迄未开挖。

We successfully identified JSRV mRNA expression and proviruses DNA in sheep lung tissues infected with JSRV and control group has no postive signals,Validating the use of exogenous virus-specific DNA probes in the analysis of oncogenic proviral integration sites and identification of integrated exogenous proviral sequences.

用地高辛随机引物法标记exJSRV特异的env片段，制备探针，原位杂交检测SPA肺组织中的RNA及前病毒DNA，结果表明SPA患羊肺组织内有JSRVenv基因mRNA的表达，同时也检测到了前病毒DNA，而相应的阴性对照却无阳性信号，证实外源性病毒特异的DNA探针在致瘤性前病毒的整合位点和整合的外源性前病毒的检测中具有可信度。

Each of them had 3 anterior maxillary teeth restored by porcelain-fused-to-nichrome crowns, without other metal fillings or protheses.

对象：选择2006-01/12在河北北方学院附属第一医院口腔修复科就诊的60例上颌前牙有3颗行镍铬合金烤瓷冠修复的患者为实验组，男28例，女32例，平均40岁，均无其他金属充填物和修复体者。

MMPs are usually secreted as latent, inactive proenzymes, which need to be activated (Fig 1 ), and/or are bound to their native inhibitors, the tissue inhibitors of metalloproteinases.8 Activation may involve proteolysis and/or oxidation of the latent enzyme.8 Proteolytic activation of the proenzymes cleaves the propeptide sequence, which masks the active site of the latent enzyme.

金属蛋白酶常以无活性的酶原方式分泌，而后者要么需要被激活要么与附近的或组织中金属蛋白酶抑制物结合。激活作用包括了具有潜在酶的蛋白水解作用或氧化作用。酶原的蛋白水解激活作用能将掩盖活性部位的潜在酶的前肽序列破坏。
