Environment radon is mainly from rock and soil in geological environment, but the research is not connected with geological environment now. On the basis of physical field, the theoretical distribution model of radon in soil and exchange model of earth—air are set up by using Fick diffusion law and Dacy law, and then the research of environment radon is linked with geological environment. This paper described how the evry parameter of the theoretical model influence the radon concentration in air. The results of research indicat that molecule diffusion of radon is different from it's eddy form. Under the condition of surface radon source, the model experiment is used to study the transportation and distribution of radon in medium. The data of experiment show the relationship between radon and depth can be described by exponent. If the radioelement is well—distributtion, the concentration of radon in different depth or in different point at the same depth change with time, but the accumulated exhalation amount of radon at different point on the surface of model are close in relative long time. The author studied the exchange of radon between mediums and verified the theoretical models too.

环境氡主要来自岩石、土壤，而目前环境氡研究中与地质环境结合很少，为此作者以物理场为基础，运用气体运移的费克扩散定律和达西定律，建立起壤中氡浓度分布与大地—大气间氡交换理论模型，首次在理论上将环境氡与地质环境结合起来；论文中从理论上讨论了模型中各参数对空气中氡浓度的影响，发现空气中氡运移的分子扩散方式和湍流扩散方式存在明显差异；通过面状氡源条件下的氡运移模型实验，研究了介质中氡的运移与分布，实验数据表明氡浓度随深度的变化规律可用指数函数描述，在放射性元素分布均匀的条件下，介质中不同深度和同一深度不同点的氡浓度随时间而变，但介质表面不同点在较长时间内向空气中累计释放的氡的量是相近的；同时研究了不同介质间氡的交换，并验证了所建立的理论模型；运用理论模型预测青岛市城区壤中氡浓度、江西临川一住宅区空气中氡浓度及江西二个测区的区域空气中氡浓度分布，取得了较好的效果。

This is very important in modern lens, the reflective glass surface decreased, so that there is more than a dozen pieces of the zoom lens on a reflective glass surface will be much less, so that the light through the lens will not be significantly reduced.

这在现代镜头上非常重要，玻璃表面的反光下降，这样在有十几片镜片的变焦镜头上的玻璃表面的反光就会少很多，这样通过镜头的光就不会明显减少。

I was experiencing seducer's paradox: The better a seducer I became, the less I loved women.

These days many actresses tend to be dressed skimpily to draw the attention of the media. Regarding this issue, Eric expressed,"In fact, to dress skimpily may not be sexy.'Sexy" is actually a kind of feeling.

现在不少女星都是靠暴露性感来博出位，对此孙耀威就表示："其实并不是穿得少就是性感，性感其实是一种感觉，有时候一双鱼网丝袜，一只特别的唇膏颜色都可以让女孩子变得很性感。"

Highelevation and lowreliefsurface,which is preserved between large rivers in SE plateau,is generically linked to the lowrelief surface in plateau interior and shows a gradual transition to less preservation because of southeastwardly increased river incision.

虽然随着河流下切深度往南逐渐增加，残留面虽越来越少，但仍然可以识别，最终终止在雅砻江逆冲断裂带附近，该断裂带以南地区没有明显负地形特征。北东向展布的雅砻江逆冲断裂带对应着50～200 km宽的地形相对陡变带。

But rare is the book on evolution theory that tells the story of steadfastness.

不过，进化理论的书很少讲述关于不变的故事。

When a woman decides to use one of these tools, their hair becomes flat and free of curls without damage, because the heat they output is much less damaging than steam and standard flat iron hair straighteners in general.

当一个女人决定使用这些工具，他们的头发变得平坦和自由的卷发而不损坏，因为它们的热量要少得多产出比蒸汽破坏和标准持平铁头发直一般。

It's quite convenient, since there's one variable less to worry about. If you get the grind, and tamp right, you can do other stuff while pulling a shot - eg. make breakfast, or lunch, or get the milk from the fridge.

这真的是挺方便的一项设计，至少我们可以少担心一项变因了，只要你把研磨、填压都搞定，冲煮过程中你还可以顺便去做其他的事。

In the course of the extension of subsoiling mini-till,small shar-ed subsoiler is screened from 8 kinds of tillage practices to carry outshallow plowing and interval subsoiling,shallow plowing is 7-8 cmdeep.and at the interval of 35 cm,the subsoiling is 20-35cm deep.Thus,the co-exitence of loose and compact tilths is created(ratiobetween the loose and compact tilths is 3:4).Owing to the unchan-ge of surface soil position,water,fertilizer,aeration and heat are incoordination,and yield increase is stable.when...

在试验推广深松少耕法的过程中，从八种耕作措施中筛选出用小铧杆尺深松犁，进行浅翻间隔深松，浅翻7—8厘米，间隔35厘米，深松20—35厘米，创造的虚实并存的耕层(虚实比8∶4)，由于表土位置不变，水、肥、气、热协调，增产效果稳定，种小麦、大豆平均增产分别为21.6%和15.5%；而且还有节省油料、降低成本，不用大量增添新的耕作机具的优点，并具有明显的抗旱、抗涝、防止土壤风蚀、水蚀的结果。
