New bought a one likes to books, paper-based is kind of the Special is important to keep them lightly pico yellowed's original health certificate is the disguise of dictionary on a leash, and the light-blue hardware binders, is a share greatly windows the bedroom, blue-the floret shrug it off on a wooden the old on the floor,, streak 兰 masked whip up kicks exposed below a pure-white bed-linen, Pan Hu Hu the two big pillows rely on together, on one of the walls arbitrarily hung simple Photo Frame, the visibility of window, to clean the weather, the bluer sky and white-yun, the Green tree, there in sight for the garbageman Rope 松松, scattered and, scattered and Da Zhe the clothing, a pair of Silver SHOES IN, slender shoelace Shuan-in Rope, Feng Er Qingbai......

前一阵子，新买了一个喜欢的本本，纸质是那种特别轻巧微微泛黄的原生纸，包装成字典的样子，淡蓝色的硬封皮上，是一间有着大大窗户的卧室，浅兰的小花洒落在木制的老旧的地板上，条纹兰的被罩掀起一脚露出下面洁白的床单，胖乎乎的两个大枕头靠在一起，一面墙上随意挂着简单的像框，望向窗外，干净的天气，蓝的天，白的云，绿的树，还有近在眼前的纤细绳上松松散散搭着的衣物，一双银色的舞鞋，细长的鞋带拴在绳上，风儿轻摆。。。。。。

The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

方法回顾性分析200例行适应性前瞻性心电门控双源CT冠状动脉血管成像的患者(排除扫描过程中，屏气配合差，出现心律不齐的患者及行支架置入或搭桥术后复查的患者)，包括屏气时平均HR≤75 bpm患者122例，HR≥91 bpm患者78例；其中30例同期行选择性冠状动脉血管造影，按屏气时HR将其分为2组，A组17例：HR≤75 bpm，B组13例：HR≥91 bpm，分别与金标准SCAG对照，计算2组患者的阳性诊断准确率，应用SPSS 13.0统计学软件，利用Kappa检验比较每组患者的2种诊断方法诊断结果的一致性，利用两样本率x~2检验，比较2个心率组间的诊断准确率有无明显统计学差异，并计算此30例患者的平均有效辐射剂量。

And tastes of each of the goods have a soft heart and brittle heart of the sandwich, there are two different options, so it can be given to pairs of new ideas, to bundling, the market for such products to make up for gaps, market has great potential.

并且本品的每种口味都有软心和脆心有两种不同的夹心可供选择，所以可以赋予其成双成对的新理念，将之捆绑销售，弥补市场上此类产品的空白，市场潜力巨大。

The copper atom changed six-coordinate in a distorted octahedral configuration to five-coordinate in a distorted trigonal bipyramidal configuration.

在2个配合物中，金属Cu的配位数都由前体中的6转变为5，由原来前体中的畸变的八面体结构转变成畸变的三角双锥结构。

The results showed that the addition leading to -2-phenyl-2-(2-vinylpiperidin-1-yl) ethanol 7 could proceed with good diastereoselectivity and excellent yield (95%).(3) The selective N-deprotection of -2-phenyl-2-(2-vinylpiperidin-1-yl) ethanol 2 without affecting the vinyl group in the substrate were untaken.(4) The Zip reaction for the transformation of -1-(3-aminopropyl)-3-methylazecan-2-one 8 to -7-Methyl-1, Sdiaza-cyclotetradecan-6-one 9 were undertaken. The results showed that, under controlled conditions, acceptable yields (43%) could be achieved and racemization can be minimized during the ring expansion reaction.

该合成路线与文献方法相比，反应条件较温和，也缩短了反应时间；(2)哌啶衍生物2与乙烯基格氏试剂进行加成反应的条件和立体选择性，取得了较好的结果（差向异构体比为80：20，产率95％左右）；(3)不饱和哌啶衍生物7在不影响碳碳双键的情况下去除苯基甘氨醇手性辅助基的条件；(4)具有羰基α位手性的氨基酰胺8在不同条件下经Zip重排反应转变为9的反应，控制反应条件，可使反应中消旋化减小到最小的程度。

At the approach of spring the red squirrels got under my house,two at a time, directly under my feet as I sat reading or writing,and kept up the queerest chuckling and chirruping and vocal pirouetting and gurgling sounds that ever were heard; and when I stamped they only chirruped the louder, as if past all fear and respect in their mad pranks, defying humanity to stop them.

春天临近时，赤松鼠来到了我的屋子底下，成双作对，正当我静坐阅读或写作的时候，它们就在我脚下，不断地发出最奇怪的卿卿咕咕的叫声，不断地长嘶短鸣，要是我蹬了几脚，叫声就更加高，好像它们的疯狂的恶作剧已经超过了畏惧的境界，无视于人类的禁令了。

For the calculations of Mon (n= 2-55) clusters, the linear and planar clusters have a strong tendency to form diatomic pairs to assemble short-long bonds alternation structures which makes them like non-metallic clusters, the short bonds are characterized as covalent non-metallic bonds and the long ones are much like weak metal bonds.

本文首先计算了各种不同结构的Mon（n=2-55）原子簇，发现一维和二维Mo原子簇表现出了一定的非金属原子簇的性质，簇中原子有明显的成双原子对趋势，致使原子簇具有短-长键交替的几何结构，短键和长键分别呈现强共价键和弱金属键的特性。

The two strands of the double helix are linked by pairs of nucleic acids like the treads in a spiral staircase.

这个双螺旋结构的两股之间是由成对的核酸联结的，它们就像螺旋式楼梯中的踏步板。

I found later that they had something in common that they still could be described as childish, goodhumoured with sparkling eyes, no matter what high position they got in the eyes of their posterities.

后来我发现她们的共性，无论她们已经在后人的神话里尊崇到了什么地位，但是她们依然被描述成孩子气的，兴致勃勃的，一双眼睛闪闪发光的。

Through computer simulation, such patterns are generated and then analyzed by using variance: mean method and nearest neighbor distance method.

通过计算机模拟实验，可以说明方差/均值法和最近邻体距离法都不能够说明小规模上的均匀性，而把这样的双规模格局大都检验成随机的或聚集的。

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！
