To evaluate bone mineral density of normal humans in Henan of China,BMD of whole body,lumbar vertebrae,upper and lower limbs and pelvis of 417 healthy subjects was measured by Hologic 4500W dual energy X-ray absorptiometer made in USA.Only BMD of limbs and pelvis was analyzed.

为了解我国河南地区正常人骨密度的数据，作者应用美国Hologic生产的双能X线4500W型骨密度仪，对417例正常人进行了全身和腰椎正、侧位检测，现就四肢和骨盆骨密度的测试结果加以分析。

But in the + moiety, the three benzimidazole rings shared the whole space equally, the dihedral angel among them is about 120°, just like three fan blades of an airscrew, the molecular structure appear gear-like shape.

X-射线单晶衍射测试、红外、紫外等方法确定了三(2-苯并咪唑亚甲基)胺的Fe和Co配合物的结构，由晶体结构发现金属配位情况不同、配合物在结构上存在着差异，Fe为八面体构型，而Co为三角双锥构型；其次，两配合物中的苯并咪唑环间夹角不同，配合物中包含N2和N4的两个苯并咪唑环间夹角仅为9.41(0.11)，几乎构成一个平面，呈蝴蝶形；后者Co三个苯并咪唑环几乎平分了整个空间，它们之间的夹角约为120，呈三扇叶螺旋桨式构型，为齿轮形。

The mismatch or match segments of gated DISA imaging were defined by two experienced physicians of nuclear medicine who are not aware of clinical data. Regional wall motion score were interpreted as 16 segments system by American Echocardiography Association in 5 score: 0=regional wall motion normal; 1=slight decrease of regional wall motion; 2=severe decrease of regional wall motion; 3=dyskinesia; 4=akinesia.

门控DISA SPECT结果，由两位核医学科医生采用双盲法判断心肌灌注／代谢匹配情况，并根据美国超声心动图学会16段法分段，以5分法判断各节段局部室壁运动记分：0分=局部室壁运动正常；1分=运动轻度减低；2分=运动明显减低；3分=无运动；4分=反向运动。

The final refinement converged to R=0.0686 and 0.0688. In the two complexes, the metal atom is coordinated with one nitrogen atom of alkylamine and three sp^2 nitrogen atoms from NTB and one oxygen atom from H~2O to form a distorted trigonal-bipyramid configuration.

配合物中的金属原子与配体NTB分子中的一个烷胺氮原子、三个sp^2氮原子和一个水分子中的氧形成五配位的扭曲三角双锥构型。

Nor can the amassment of roughly a hundred international and local artists say anything significant about their specific culture or nationality without deflating the principles of modernity in a global footprint.

在没有违反全球现代性的原则下，这双年展的100多位国际及本土艺术家也不能提及有关于他们的具体文化或国籍。

The girl is a woman that graceful graceful jade establishs, orange amice of Juan Xiu is sent, the melon seed face that Bai Xi shines completely, attack below the brow of willow Xie Shi showing eyelash to grow nucleus of long a pair of apricot big.

姑娘是位婷婷玉立的女子，隽秀的橙色披肩发，白晰净亮的瓜籽脸，柳叶似的眉毛下扑闪着睫毛长长的一双杏核大眼。

Nereus mated with one of the Oceanids and became the father of fifty daughters called Nereids ; three of these are important: Thetis , Galatea , and Amphitrite .

海神与海洋女神之一成双成对并且成为五十个女儿的父亲称为涅瑞伊得斯；这三位很重要：西蒂斯， Galatea 和安菲特律特。

By extending the concept of MBE technique and employing the uniform buffers to separating the sample electrophoresis, the zone electrophoresis was developed. The isotachoporesis technique is based on the separation in a discontinuity form between two buffer solutions and results in separation of samples. The isoelectric focusing is a method that concentrates the ampholyte sample by the pH gradient introduced in the background ampholytes.

区间电泳法以移动边界电泳法作为基础的技术，其在系统环境充满均匀的缓冲液进行分离；等速电泳法则利用两缓冲液进行不连续分离之技术；等电点聚焦电泳法则利用背景溶液建立出pH值梯度，双性电解液样品因其位於等电点所受库伦力为零而聚焦於此。

The α-BaB〓O〓 crystal is colorless, transparent and without cracking. The cracking problem has been overcome by a special growth procedure. The dislocation density, crystallization morphology and growth habit of α-BaB〓O〓 crystal have been systematically studied by chemical etching method, X-ray laue orientation of synchrotron radiation, double-crystal diffraction topography. The growth striation and irregular dislocation consist of the primary defect in α-BaB〓O〓 crystal. The convex solid-liquid interface is stable during the whole growth process.

在国际上首次采用提拉法生长出φ50×40mm〓的α-BaB〓O〓晶体，生长方向为[0001]，晶体完整、无色透明；提出了三种固相反应的原料制备方法，并保证B〓O〓过量1mol%；采用独特的生长装置和程序有效地解决了α-BaB〓O〓晶体易开裂的问题；首先采用化学腐蚀法、白光X射线衍射术、X射线双晶衍射形貌术等研究了α-BaB〓O〓晶体的位错密度；首次采用同步辐射X射线劳埃定向术研究了α-BaB〓O〓晶体的结晶形态及生长习性；结果发现α-BaB〓O〓晶体的缺陷以位错为主，部分α-BaB〓O〓晶体中存在生长条纹。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
