The roughness shape of ceramic machining surface is analysed by four kinds of test methods: surface profile, scanning electron microanalyses, bearing ratio curve and profile ratio of peak to valley. Ceramics are machined by"plateau honing"to obtain the plateau property and wearability of machining surface. The machining surfaces own its functional surface.

采用表面微观轮廓、扫描电镜观察、表面支承长度率曲线以及表面轮廓峰谷比等四种研究方法，详尽分析了陶瓷材料加工表面的轮廓形状特征，并采用平顶珩磨加工方法，获得陶瓷加工表面的平顶特性，提高了加工表面耐磨性。

The truth is,that she was ravishing in every respect, and that she distinguished the difference between a bonnet from Gerard and one from Herbaut in the most marvellous way.

事实是：她在任何方面都是楚楚动人的，并且能万无一失地分辨出哪顶帽子是热拉尔铺子的产品，哪顶帽子是埃尔博铺子的产品。

To wit, the two pillars, and the pommels, and the chapiters which were on the top of the two

所造的就是两根柱子和柱上两个如球的顶，并两个盖柱顶的网子

Air is clean spend and fall next bacterium are current air of product of province IVC system, isolator purifies Jiangsu to roughly two kinds of air current organize means, one kind sends a top to answer for the top: IVC remands wind filters through containing directly top of basket case case, horniness isolator remands on ben top wind; remands another kind to be the same as one side parallel: IVC remands wind contains filter film with a side face in basket box undertake inside aperture, soft qualitative isolator is sent by ben a side wind is answered on wind, means of two kinds of air current all is be not one-way and popular form.

目前实验动物相关国家标准对此类设备各项技术指标的检测并无说明，笔者对该类产品按江苏省地方标准[1]检测进行了初步的探索。1空气洁净度和落下菌目前江苏省IVC系统、隔离器产品空气净化大致有两种气流组织方式，一种为顶送顶回：IVC送回风直接通过含有过滤膜的笼箱盒盖，硬质隔离器在内室顶上送回风；另一种为同一面平行送回：IVC送回风在笼箱同一侧面含有滤膜孔内进行，软质隔离器由内室一侧送风对面回风，两种气流方式均为非单向流行式。

He is from seven to thirteen years of age, he lives in bands, roams the streets, lodges in the open air, wears an old pair of trousers of his father's, which descend below his heels, an old hat of some other father, which descends below his ears, a single suspender of yellow listing; he runs, lies in wait, rummages about, wastes time, blackens pipes, swears like a convict, haunts the wine-shop, knows thieves, calls gay women thou, talks slang, sings obscene songs, and has no evil in his heart.

他的年龄在七至十三岁之间，过着群居生活，在街上游荡，在野外露宿，穿着自己父亲的一条破裤，拖着鞋后跟，顶着另一父辈的一顶破帽，压过耳朵，挎着半副黄边背带，东奔西跑，左张右望，寻寻觅觅，悠悠荡荡，把烟斗抽到发黑，满嘴粗话，坐酒铺，交小偷，逗窑姐，说黑话，唱淫歌，心里却没有一点坏念头。

The bottom frustum and the top face shall be scabbled to flat. The bottom face shall be no less than 60% of the top face.

底面截锥体、顶面应粗琢平整，底面积不应小于顶面积的60%。

When content of Nicotine increased, protein decreased in leaf and root of toped tobacco. This probably because the content of IAA decreased rapidly and acted as the first signal to transfer to root in toped tobacco, and this made the second signal 桝BA and ZR increased, activated biosynthsis of Nicotine.

打顶以后烟碱含量增加的同时，叶和根中的蛋白氮含量均降低，还原糖含量增加，这可能是由于打顶以后，IAA的迅速降低作为第一信号，沿木质部向下运输到根，引起根部的第二信使一ABA、ZR等含量的增加及GA；含量的减少，激活烟碱合成的三种酶，使总氮中用于合成蛋白质的氮减少，自由氨基酸增加，促进烟碱的合成。

In the toped and untoped tobacco when applied with hormone, both content of IAA and GA3 increased but others decreased in tobacco that treated with IAA and GA3; The content of ABA increased significantly but the content of IAA and GA3 decreased when applied with ABA.

打顶与不打顶喷施外源植物激素的处理中，IAA和GA_3均可使叶和根中该激素含量提高，而其他激素含量下降；喷施ABA可以使烟株体内ABA明显增加，IAA和GA_3含量下降，ZR略有增加，但增幅不大。

The experiments were done from 1999 to 2001. Effects of exdogenous hormone on content of Nicotine and hormone were studied in flue-cured tobacco which were treated with exdogenous hormone when toped and untoped.

本文于1998年—2001年研究了烤烟(NC89)烟株打顶与不打顶状况下外源喷施植物激素(IAA、GA_3、6-BA、ABA)及TIBA对烟株体内烟碱合成和激素的影响。

Because biosynthsis of Nicotine was rapid in the 0-10 days after toping, if plant hormone was used to regulate content of Nicotine in production, it had better be applied in the toping day.

由于烟碱的合成在打顶后0叶0天较快，因此，施用植物激素调控烟碱含量应当及早进行，最好打顶当日即施用。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
