The diagnostic accuracy can be improved using the CT guiding spring core biopsy needle for percutaneous pulmonary biopsy for both malignant tumor and benign lesion. Especially for benign lesion the diagnostic accuracy with spring core biopsy needle was distinctive higher than that with fine needle aspiration.

CT导引下使用弹簧芯状活检针经皮肺穿刺活检的并发症发生率与细针针吸活检相近，对肺内良性病变和恶性肿瘤的诊断准确性同样具有较高的准确性，特别是对肺内良性病变的诊断准确率明显高于针吸活检。

After a good design, may constitute a good sound absorption structure to noise, sound-absorbing.

经过良好的造型设计，可构成良好的吸声结构，达到隔声、吸音的作用。

At pump start before the shell and the water pump tube must be filled with water, the air This is because there is existence, the population vacuum pump can not create and maintain.

水泵在启动以前，泵壳和吸水管内必须先充满水，这是因为有空气存在的情况下，水泵吸人口真空无法形成和保持。

In the plastics industry by more than a decade of Mr. Chen Wuning was established in 2001, after I plant continued efforts of all staff, is now developed into one with PVC PET sheet machines and the most advanced of several high-speed Blister, on Production sheet in 300 tons of plastic over 100 tons, and have their own product research and development centers, able to provide customers from the sheet - mold - Daomo - finished one-stop production services business.

是由从事塑料行业十数年的陈武宁先生成立于2001年，经过我厂所有员工不断努力，现发展成为一家，拥有PVC PET 片材机及国内最先进的高速吸塑机数台，月生产片材300于吨，吸塑100多吨；并拥有自己的产品研发中心，能为客户提供从片材－模具－刀模－生产成品一条龙服务的企业。

Our Business: High-speed automatic vacuum plastic molding machines; system Cup, Hydraulic Jae-off, triangular Flap machines, packaging sealing machine, sheet machine, plastic mold, hardware supporting all kinds of plastic equipment.

本厂经营范围：高速全自动真空吸塑成型机；制杯机、液压栽断机、三边折边机、包装封口机、片材机、吸塑模具、五金各种吸塑配套设备。

Before the motor is in overhaul status confirmed; screw under the plug come on, put to use straw sealed cavity lubricants Block aspiration.

2拆前确认电机处于检修状态；拧下加油螺塞，用吸管把密封座腔内的润滑油吸出。

Also, because oil-absorbing tube 6 in the role of one-way valve 7, compressed air will not flow backward into the oil pipe from the oil-absorbing cup, so we can keep gas in a state of the oil gagged refueling, refueling is completed, screw plug oiling .

又由于吸油管6中单向阀7的作用，压缩空气也不会从吸油管倒灌到油杯中，所以就可以在不停气的状态下向油塞口加油，加油完毕，拧上油塞。

The results show that boundary layer suction can restrain the corner separated flow, weaken the intensity and scale of passage vortex, and improve the cascade flow capacity.

结果表明，采用吸力面两端吸气对抑制角区分离流动、减弱通道涡强度和尺度、提高叶栅内流动性能的效果要优于其它两种方式，积聚在角区的低能流体由于较大的吸气量而被大量吸除是性能改善的关键。

With the nitrobenzene、 m-chloronitrobenzene、 m-nirtobenzenesulfone sodium salt for bottom thing, Grinard agent is a nucleophilic reagent reaction for under the different term proceeds a series reaction.

以苄基氯化镁为亲核试剂，以硝基苯、间硝基氯苯、间硝基苯磺酸钠为底物进行亲核取代反应，探讨与芳环相连的吸电子基团的数目及吸电子性，对亲核取代反应的影响。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
