I find some embers left as if he had but just gone out, where he baked his pot of beans; and while at evening he smoked his pipe, whose stemless bowl lies in the ashes, chatted with his only companion, if perchance he had any about the depth of the snow on the morrow, already falling fast and thick without, or disputed whether the last sound was the screech of an owl, or the creak of a bough, or imagination only; and through his broad chimney-throat, in the late winter evening, ere he stretched himself upon the straw, he looked up to learn the progress of the storm, and , seeing the bright stars of Cassiopeia's Chair shining brightly down upon him, fell contentedly asleep.

我发现还有一些用来烘焙豆子的余灰，这又似乎说明他仍未走远；我们好像看到晚上他抽着烟，烟斗被放在灰中，他和朋友聊着天，讨论着明天降雪的深浅，或者争论刚才的声响是猫头鹰在叫还是树枝在颤动，抑或是自己的错觉；通过向烟囱外张望，他察看了一下外面风雪的情况，却发现仙后座的星光清晰地照在自己身上，然后他舒服地伸了个懒腰，爬到草堆上，沉沉睡去。

So, the aromaticity of acenaphthenyl groups in C_2 gum should be the least. In order to explain the reason, quantum chemical calculation is utilized. The optimized geometrical structrures of condensed aromatics in C_1 gum, C_2 gum and C_3 gum are calculated at B3LYP/6-31G* levels. We find that some phenyl groups in acenaphthenyl groups are coplanar and have the largest conjugated structure.

为了解释其原因，我们利用量子力学方法进行了计算，研究了三种稠环基团在B3LYP／6-31G*基组水平下优化得到的几何结构，发现苊式多苯基苯基中的萘环和中间的苯环共面，电子离域性最大，而其他二者所有苯环都不共面，发生了明显地扭曲；同时，在优化几何结构的基础上，对三种化合物进行了前线分子轨道的分析，利用密度泛函理论方法(density function theory，DFT)计算了稠环基团的最高占有轨道和最低未占轨道之间的能量差，即能隙，发现C_2胶上苊式多苯基苯基的Eg最小，解释了C_2胶具有最好的辐射保护效果的原因。

Using stereomicroscope, we observed the fracture line direction and location as well as the angle between the fracture line and the attrite plane. The data was compiled into statistics and analyzed. The results revealed that most of the vertical root fractures occurred in teeth with severe attrite crown and flat root. Numerous bucco-lingual oriented fractures occurred in the mesial root of molars, and we found three non-endodontically treated cases with mesio-distal oriented fractures in the palatal roots.

结果发现，两组的垂直牙根断裂均好发於牙冠严重磨耗（77.4-88.2%）且扁平的牙根（61.8-75.8%）上，以大臼齿的近心牙根发生率最高（64-85.7%），多为颊舌侧走向（91.2-91.9%），且於未根管治疗组别亦发现三例腭侧根断裂，走向为较宽的近远心方向，显示牙根断裂会沿著牙根较宽的方向发生；同时，未经根管治疗而产生垂直牙根断裂的牙齿具有根叉位置较低的现象（61.8%），牙根於比例上有较短小的特徵。

objective to study the ct diagnosis of ureteral calculus at the distal end of ureter.methods 82 cases of ureteral caculus were examined by ct scanning.all cases were proved by clinical therapeutic results.results ureteral calculuses were showed as high density image in ct scanning.the ct values of the ureteral calculuses less than 7.5mm in diameter were beyond 83hu.the detection rate by ct was 96.3%.in all the 82 cases,ureteral with calculuses were found dilated and 69 cases with nephrohydrosis.in 13 cases with no nephrohydrosis,caculuses less than 3.8 mm in diameter were found.conclusion ct is the most valuable way to diagnose ureteral calculus at the lower end of ureter.appropriate methods of ct scanning are essential.

目的 回顾性分析输尿管膀胱入口处结石的ct诊断结果，评价其ct检查的临床应用价值。方法分析82例输尿管膀胱入口处结石的ct检查结果，所有病例均经尿道排石证实。结果输尿管膀胱入口处结石具有特征性的ct表现，即圆形或枣核状钙化高密度影，结石直径＜7.5mm，ct值≥83hu，ct确诊率96.3%。82例均发现病侧输尿管增粗，69例发现病侧肾盂少量积水，肾盂未见积水的输尿管膀胱入口处结石13例，其结石直径＜3.8mm。结论 ct检查输尿管膀胱入口处结石具有准确、无创、直观等优点，是诊断输尿管膀胱入口处结石不可替代的检查方法。

The place that rawish effect can reflect on the website most is the BUG of the program, if a member that the program is developed perhaps opens source program on the net,undertaking fair when measure or failing to discover BUG in time, be eager to going up line, to on the BUG that discovery of the ability after the line still has a lot of can bring the person that visit an undesirable impression so!

夹生效应最能在网站上体现的地方就是程序的BUG，如果一个程序开发员或者网上开源程序在未进行公测或者未能及时发现BUG的时候就急于上线，到上线后才发现还有很多的BUG这样就会带给访问者一个不良的印象！

We have multiple systems of mirror neurons, with more being discovered as time goes on. There seems to be a multitude of such neural systems that remain as yet unmapped.

大脑中存在着多重运行的镜子神经系统，而且随着时间推移，越来越多的这种系统被发现，但似乎还有很多的这种系统未被发现。

I've been in this business for thirty years.I've never had to call the police to eject a disorderly dog.Never had a dog set fire to a bed with a cigarette.I've never found a hotel towel or blanket in a dog's suitcase.

我为它作的译文如下：我在这个行待了30年，从未召来警察将无法无纪的狗赶出去，也从未发现有狗在床铺上纵火，更未在狗的箱子里发现有酒店的毛巾或毯子。

Help the discussions above is useful for the relative research in the future. From experiment, we found the gussets buckle without stiffeners. After adding stiffeners at the edges of gusset, the buckling of gussets never occurred.

试验过程当中发现斜撑之接合板在未加劲之下会产生挫屈的现象，而在加劲过后挫屈现象便受到有效的控制，分析中发现亦可以缩短斜撑端部与所接梁柱之距离来避免接合板挫屈的发生。

Ti element is found to aggregate, forming an ultra-fine reaction layer in the active filler metal-ceramic joint after 260℃/24hr aging treatment. Two different-color intermetallic compounds are observed in the interface of active filler metal-copper. One is Cu6Sn5 , which is closer to active filler metals;the other is Cu3Sn, which is closer to the copper substrate.

接合后之试片，经260℃/24hr时效反应后，发现Ti元素聚集於焊料与陶瓷界面处形成一层极薄的反应层且发现在焊料与铜之反应界面有了明显颜色不同之两层介金属层生成，靠近焊料端的介金属层为Cu6Sn5，Cu片端的是Cu3Sn；而Cu6Sn5化合物从原本未时效10μm成长为25μm。

The empirical study discovers that:(1) The information technology companies in Taiwan that invest in China shows better financial performance, growth opportunities and company assets than those that don't. It indicates that the companies investing in China have better performance, higher growth in the future, and the tendency to expand;(2) In terms of the relationship between the scale of investment and the performance of the parent companies, the information technology companies listed in Taiwan show an S curve while the top 100 information technology companies in 2005 lead to a U curve, which indicate that information technology companies adopt different management methods at different stages. The enterprises with better sales don't exceed the optimal degree of investment;(3) The growth opportunities of the information technology companies listed in Taiwan investing in China have positive

实证结果发现：（1）台湾资讯电子业赴大陆投资在财务绩效、成长机会与母公司规模皆高於未赴大陆投资者，显示出赴大陆投资者绩效较好、未来具有较高的成长、有大型化的趋势；（2）台湾上市柜资讯电子公司与2005年前百大排名电子公司大陆投资程度与母公司绩效关系分别呈现S型与U型，显示资讯电子业在不同阶段有不同的经营模式，营收较佳的企业未超过最适的投资程度；（3）台湾上市柜资讯电子业赴大陆投资之成长机会对财务绩效具正向影响，显示出大陆投资之成长机会愈高，则有较佳的财务绩效；（4）台湾上市柜资讯电子业之大陆投资程度会影响母公司成长机会，显示随著大陆投资程度的变动，明显牵动母公司的成长机会。
