These physicochemical data of above experiments, such as bulking density, specific surface area and pore volume are determined.

实验完成后，对这几种干燥实验的样品，分别进行了主要物化性能，如堆积密度，比表面积和孔容积的测定。

Methods Fresh litchi peel was air-dried, extracted with 70% ethanol solvent in ultrasonic wave. The extract was then purified with D101 macroporous resin adsorption chromatography, C18 solid phase extraction and high performance liquid chromatography. And the component purified was identified by mass spectrography.

新鲜荔枝果皮阴干，用70％乙醇溶液以超声波浸提法提取，提取液经过D101大孔树脂吸附层析、C18小柱固相萃取、高效液相色谱法分离、纯化后，采用质谱法鉴定结构。

After being registered accurately with Photoshop 7.0 software, the male urological and reproductive organs such as kidney, adrenal, ureter, bladder, male urethra, prostate, spermaduct, seminal vesicle and the adjacent organs such as abdominal aorta, inferior vena cava, thoracic duct, the lymph nodes beside abdominal aorta, the nephritic artery and vein, the intrailiac artery and vein, pelvis, the prostatic plexus and internal obturator muscle can be segmented and surface rendering three-dimensional reconstructed with 3D-DOCTOR software.

断面图像数据集经Photoshop 7.0软件精确对位、配准后，应用3D-DOCTOR 4.0软件，分别对男性泌尿生殖系统的肾脏、肾上腺、输尿管、膀胱、男性尿道、前列腺、输精管、精囊腺和泌尿生殖系统的毗邻器官腹主动脉、下腔静脉、胸导管、主动脉旁淋巴结、肾动静脉、髂内外动脉、骨盆、前列腺周围静脉丛、闭孔内肌等进行数据分割和三维面绘制重建。

The solution is filtered and pumped through the fine holes of a spinneret.

纺丝液经过滤后，借助于泵的压力穿过喷丝头的细孔。

Also, after the first opening process, the contents of the container does not dispense through the spouting hole of the spout.

并且，在第一次打开后，容器中盛放的物质不会通过喷管的喷射孔倒出。

After adjusting and installing with the spring balance bring 20-40N ( as illustrated in figure 3) to bear on bolt hole in the small gear hub, the flange should be able to turn.

调完安装好后，用弹簧秤在小齿轮壳螺栓孔处施以20－40N 的力（如图3），应能转动突缘。

Because the strength of springwood was very low, the strength of board which included more springwood was low. The main reason why there was no difference in wet compressing shear strength between quarter-sawn board and flat-sawn board was that quarter-sawn board had a lot of pits on radial cell wall and in flat-sawn board xylary rays were transversely cut and left a lot of pores which provided a kind of tunnels for water.

造成柞木径切板的反复煮沸压缩剪切强度与弦切板的反复煮沸压缩剪切强度没有显著性差别的主要原因是柞木细胞壁径面上的纹孔很多，而弦面上的木射线在经刨削后是横断的，留下许多孔隙，这使得弦径向均有成为水分通道的孔隙，造成柞木径切板的反复煮沸压缩剪切强度与弦切板没有显著性差别。

By traditional method of design, the elastic theory is adopted to calculate stress distribution, and the amount of reinforcing bars for the orifice is determined according to the diagram of tensile stress.

这种方法不能反映混凝土和钢筋两种材料的非线性性质以及混凝土开裂后引起的应力重分布，并且不能有效地控制孔口的开裂，按照此方法计算的配筋量往往偏大。

In 68 patients (75 eyes), there were 45 cases whose initial diagnosis was Coats disease while the final diagnosis was not, in whom the final diagnosis was old retinal vein occlusion in 21, retinal vasculitis in 9, diabetic retinopathy in 3, old posterior uveitis in 3, congenital retinoschisis in 3, and proliferative vitreoretinopathy, familial exudative vitreoretinopathy, racemose hemangioma, old rhegmatogenous retinal detachment, macular epiretinal membrane, and idiopathic juxtafoveal telangiectasis in 1, respectively.

68例75只眼中，初诊为Coats病，最后确诊为非Coats病45例。其中，最后诊断为视网膜静脉阻塞21例；视网膜血管炎9例；糖尿病视网膜病变3例；陈旧性后葡萄膜炎3例；先天性视网膜劈裂症3例；增生性玻璃体视网膜病变、家族性渗出性玻璃体视网膜病变、视网膜蔓状血管瘤、陈旧性孔源性视网膜脱离、黄斑前膜、特发性黄斑旁毛细血管扩张症各1例。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
