At the beginning, the common small diameter diamond coring drilling is used, but the efficiency is low, the cost is high, and the construction period is long. Subsequently, the hollow-through type DTH hammer drilling technique and continuous coring technology with reverse circulation are adopted to experiment in this mine.

中文摘要：新疆白干湖钨锡矿区自然环境恶劣，地质条件复杂，普通小口径金刚石岩心钻探方法效率低、成本高、施工周期长，后采用贯通式潜孔锤反循环连续取心钻进技术在本矿区进行生产试验。

Screen version of the seihan process is relatively simple: the first thing to liquid water-based emulsion coating of print to screen all blocked, and then set of print-and-drop to a drying oven; in the seihan, the renderer.draw business card printing and membership card making image transparency around sensitibvity too sensitive emulsion silk-screen version 5.1, and UV light sources on its exposure (because the screen typically drum-shaped, they need to be rotated screen drum).

丝网版的制版工艺也比力独一：首不后要用固态的火基型感平乳剂涂覆丝网版，以不通功所有的网孔，然后不兵丝网版不收到潮湿箱洋潮湿；制版时，不兵带有制卡和会员卡制作图像的正片环绕在涂覆功感平乳剂的丝网版滚筒上，并用UV平源不对其曝平（由于丝网印版凡是是滚筒状的，不陈必要回旋扭转网版滚筒）。

Efficiency: 18000 / 2 hours, SL series of roller bearings Paper on the roll, with high-precision production lines and advanced detection instruments, products, dust, double row ball cage structure; ball, roller Road, within the three holes after close elections After the assembly from distribution, a rotating flexible, small friction, rotation stable, good sealing performance, durable, easy maintenance, welcome to.

效率：18000支/小时二、SL系列上罗拉轴承皮辊，拥有高精度生产流水线和先进检测手段，产品防尘、双列滚珠保持架结构；钢球、滚道、内孔三者经过严密选配后组装而成，具有旋转灵活、摩擦力小、转动平稳、密封性能好，经久耐用，维护方便，欢迎使用。

Methods the angles from the body surface of yamen (gv 15) to the joint line between the level opposide atlas and axis, and the joint line between body surface of yamen point and posterior margin of the great occipital foramen, upper margin of arcus posterior atlantis were measured respectively in 1120 cases of t1 weighted image of median sigittal position with mri, and the data were processed by computer.

取1120例mri正中矢状位t1加权像，分别测量体表哑门穴至水平相对寰、枢椎椎间的连线与体表哑门穴至枕骨大孔后缘连线、寰椎后弓上缘连线所夹的角度，并由计算机进行数据处理。

Simply shortening a suit's hems and sleeves can leave the collar too broad, the pockets oversized, the armholes gargantuan, the elbow curves too low and the rear droopy.

仅仅修短衣服的下摆和袖子是远远不够的，领口、口袋、袖孔都还是太大，肘弯处太低，后摆也是耷拉着的。

This distinguishes them from mollusks and arthropods , in which this first opening becomes the animal's mouth .

这一特点将它们与软体动物和节肢动物区分开来，因为后两种动物的口都是由胚孔直接发育而来的。

Six and twelve boors after sepsis, leptin levels in liver homogenate were detected by radioimmunoassay serum alanine aminotransferase and 4 enzymes in liver homogenate. myeloperoxidase, glutathin-S-transferase, xanthine oxidase and superoxide dismutase, all related with synthesis of free radicals, detoxication and purine metabolism, were detected by 96 well spectrophotometry. H-E staining was used to examine the histopathologic changes of liver.

于脓毒症后6 h和12 h，采用放射免疫法测量肝组织匀浆液中Leptin水平，采用96孔分光光度法检测血清丙氨酸氨基转移酶及髓过氧化物酶、谷胱甘肽－S转移酶、黄嘌呤氧化酶、超氧化物歧化酶等4种与自由基合成、解毒和嘌呤生成代谢相关的酶的水平，同时以H-E染色法观察肝组织病理学改变。

Space weather disturbances may arise at short notice after events such as solar flares, coronal mass ejections and short-lived coronal holes.

空间天气干扰也许出现接到命令后立即在事件以后譬如日晕、冠状许多排斥和短命的冠状孔。

The eluents were water, 10%, 20 %, 30 % and 50 % ethanol respectively and they flowed through the macroporous resin one by one with five times of the column volume. The obtained eluent of 50 % ethanol was evaporated and the content of total flavonoids was 76 % measured by HPLC.

结果 选择AB-8大孔树脂；最佳纯化工艺为上样液总黄酮质量浓度 60 mg·L-1，pH 5.0，温度 25 ℃；最佳洗脱方式是用5倍柱体积的水及体积分数分别为10 %、20 %、30 %的乙醇依次洗脱，弃去洗脱液后再用5倍柱体积的体积分数为50 %的乙醇洗脱；HPLC法测定总黄酮的含量为76 %。

Before conducting the study, students believed that Heat could not influence gas and liquid volume.Matter didn't have thermal expansion. Metal ring's diameter will shrink after heating. The melting quantity of salt is much quicker and faster than sugar in the same temperature or water. Only metals can conduct heat, but not wood, glass, plastics. The quantity of heat is by steam way disappearing.

一、学童对「物质与热」的迷思概念有：(1)「热对气体、液体体积不会有影响」的概念，(2)听过热胀冷缩的语词，但是对原因不明了，(3)金属双圆环加热后，内环孔的口径会变小，(4)同温度且等量水，盐的溶解量比糖多、也比糖快；(5)木材、塑胶、玻璃不会传热，金属才会传热；(6)以为热量是以水蒸气方式散失，(7)冷气机应安装在高处，冷房效果较佳；(8)误认为金属是良好的保温材质。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
