Results In 84 cases of nerve root type,stenosis was found in 438 intervertebral foramen,of which C6～7 and C5～6 intervertebral foramen stenosis accounted for 79.6%.The causes of intervertebral foramen stenosis were uncinate process articulation hyperosteogeny,intervenebral disc protrusion,vertebral body hypertrophy,zygapophysis hyperosteogeny and dislocation etc.40 cases of vertbral artery type manifested that vertbral artery became slim and deviousness as a result of the compression of vertbral artery （20.7%） by osteophyte.22 cases of myeloid type manifested with cervical spinal canal stenosis,hyperosteogeny of posterior vertebral body edge,posterior longitudinal ligament calcification and cervical intervertebral disc protrusion etc.

结果 84例神经根型中，发现椎间孔狭窄438处，其中C5～6和C6～7椎间孔狭窄占79.6%，椎间孔狭窄的成因有钩突关节骨质增生、椎间盘突出、椎体肥大、小关节突骨质增生、错位等；40例椎动脉型表现为骨赘压迫椎动脉（52.5%），导致椎动脉变细、粗细不均和椎动脉迂曲。22例脊髓型表现为颈椎椎管狭窄、椎体后缘骨质增生、后纵韧带钙化、椎间隙狭窄和颈椎间盘突出等。

Also need a cover, but according to the technical requirements of spine of the three marks at the dacpot cannot be parisand, and the books even more difficult to back-office fibroarthrosis endpaper, its main function is the book after the mysteriouses book page on four spine can be started to draw an irregular trapeziform hole, the role of the hole to be capable of a four-page books turned up sufficiently to the size of the hole should be determined depending on the thickness of the books, too big or too small affect book reading efficiency.

封面同样需要过胶，但按工艺要求书脊处的三条痕线内不能有胶水，更不能和书内页的书脊处粘连，它的主要作用是书成型后，掀开书页时在封四书脊处可拉开一个不规则的梯形孔，这个孔的作用能使书本的封四页充分打开，孔的大小应视书本的厚度决定，过大或过小都将影响翻书阅读效果。

The results showed that the proportion of aspirated pits in the respective earlywood and latewood of the air_dried sapwood was increased to 99% and 81%, while that of heartwood was also as high as 97% and 86% because most of the bordered pits were aspirated at its green state.

结果表明，边材和心材的生材经气干处理后，其中边材的早材和晚材纹孔闭塞率增加至 99%和81%，而心材因为其纹孔塞在立木时就已发生偏移，其早材和晚材纹孔闭塞率亦高，分别为 97%和 86

The machined big locating hole and the raw 3-25H7 cylindriform dowel hole′s distribution circle get spheroidicity after the four over dowel holes on a kind of annular gear having been machined and given heat treatment.

在加工内齿圈上的四销过定位孔时，热处理后，已加工好的定位大孔及未加工的3-25H7圆柱定位销孔的分布圆均变成了椭圆形，安装时，又将它们撑起恢复成圆形。

Subgradient projection method with variable diameter for optimization;2. The variable diameter deephole blasting was adopted to solve problems of open-pit high bench mining.

采用变直径深孔爆破工艺可较好地解决露天矿高台阶开采的爆破根底问题，对等直径和变直径 2种深孔形式爆破后岩体移动速度情况采用高速摄影手段进行了分析和研究，为在高台阶开采的矿山推广变直径深孔爆破提供一些有益的参考依据。

Based on the recent progress in the field of mesoporous materials, the synthesis of mesoporous titania with crystalline walls was investigated in this paper.

在调研了国内外介孔材料研究领域的最新进展后，将合成具有晶型孔壁结构的介孔二氧化钛作为本论文的研究内容。

The epoxide groups of the column were modified by a reaction with diethylamine that affords ionizable functionalities required for ion exchange chromatography. The influences of the contents of the cross-linker and porogen on column pressure were investigated.

考察了交联剂及致孔剂用量对色谱柱压力的影响，发现：随着交联剂用量的减小，致孔剂用量的增大，柱压下降；当交联剂和致孔剂用量达到一定水平后，柱压变化不再明显，但柱体机械强度降低。

There were two layers of tissue in the pterygopalatine fossa,they are posteromedial nerve layer and anterolateral vessel layer.The distance from the internal carotid artery to the sphenopalatine foramen was 16.4±3.3 mm.

结果：蝶腭孔、圆孔、翼腭裂距离前鼻嵴的距离分别为(62.3±2.7)、(64.2±4.8)、(51.5±0.6) mm，翼腭窝内的结构可以分为在后内的神经层和在前外的血管层，颈内动脉与蝶腭孔之间的距离为(16.4±3.3) mm。

After 72 hours incubation, the chondrocytes were digested into single cell suspension. Then they were incubated in the 96-well culture plate with the density of 1×10^8 L^(-1), 100 μL per well and six wells for per group.

白细胞介素1β加入量为5μg/L，培养72h将实验用细胞消化传代后制成单细胞悬液，以1×10^8L^的密度接种于96孔培养板，100μL/孔，每组6孔。

To cooperate with new and old parts: although standard zero, components, but in between interchangeable in assembly parts, and to make the optimal coordination between trim, still needs a lot of work, such as the gear and rack, boring if after removal of gear various performance indicators are used by detecting without the need to change, and to replace worn rack, rack and rack positioning pin hole on installation bolt holes and should be first, reoccupy hand crossed positioning drills and tapered reamer to match the drill and match hinge, and after the installation of new and old super-modulus gear mesh clearance to achieve technical standards, this work takes about one day.

。新，旧零部件重新配合过程：尽管标准零，部件间具有互换性，但在装配中，要使新旧零部件间旳配合达到最佳状态，仍需大量旳修整工作，如镗床旳齿轮与齿条，若拆卸后齿轮旳各项性能指标经检测尚能使用不需更换，而齿条磨损厉害需更换，那么齿条嘉逸条安装面上旳定位销孔和定位螺钉孔就需先划线定位，再用手电钻及锥形铰刀重新配钻和配铰，且新齿条安装完毕后与旧齿轮旳啮合间隙需达到技术要求旳标准，此项工作需时约─天。
