针对目前国外几种无穷静刚度气体润滑轴承结构复杂、制造难度大、调整困难的不足，本文提出了一种主动控制节流无穷静刚度气体润滑轴承，将表面节流与主动控制节流相结合，使轴承动、静压效果同时获得较好的发挥；利用浅腔及锯齿形多槽结构产生较强的楔形动压效应，提高轴承的静态和动态性能；利用主动控制节流器对轴承进行压力反馈主动控制，提高轴承的承载力、刚度，并在一定载荷范围内，使轴承刚度为无穷大。

Results all the 6 patients with pap presented ground-glass opacities with well-defined margins on msct'creating "geographic" pattern'reflected the effusion of proteinaceous material within the alveoli in pap.thickened interlobular septa'looking as the "crazy-paving"'was found in 4 cases in high-resolution ct'correspondence with edema and lymphocyte exudation in interlobular septa in pathological findings.no mediastinal and hilar adenopathy was found.

Results Compared with conventional ultrasound,sonoCT could suppress the reverberation artifacts in bile duct and gallbladder obviously.Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

Lateral boundaries and adumbration of the carcinomas were improved,resolution of internal structure echos also enhanced.Thus,sonoCT raises the reliability of biliary tract tumors diagnosed by ultrasound.

结果 与传统声像图比较，胆管、胆囊腔内混响伪像明显减弱，提高了肿瘤轮廓的清晰度，增强了病灶内部结构与回声的分辨率，增加了超声诊断胆道肿瘤的可信度。

A narrow, spoon-shaped instrument for surgical extraction in cavities or cysts.

Jiang Ye Yiyang colored plant since 1997 zhejiang for the production of three Group took the body with yellow brass, there have been more than a decade of history, maturing technology, complete equipment, product quality higher than the national standards in the chemical products Composition, tolerance level of accuracy, mechanical properties, both inside and outside surface quality in areas such as technical requirements, Reflects a production capacity of enterprises, technical and management level.

化学成分，化学成分 GB/T5231—2001中的 H65化学成分范围，为使其性能更有保障，对主成分及有害杂质进行更严格控制，制订企业标准（Q/JY001—2004）。（2）公差及机械性能参照 GB/T1527—2006拉制管标准和浙江三花集团企业标准 Q/ZSH05·099—2002，制订企业标准（Q/JY001—2004），对其进行严格控制。三位四通阀的工作环境是液态或汽化的氟利昂等冷凝剂，其内腔气密性要求十分苛刻，这就需要 AC 黄铜管的内、外表面质量有极高表面质量，内、外表面光洁，无划伤、拉痕、起皮、沙眼、夹杂等加工缺陷，无酸、油、润滑等残留附着物。由于 AC 黄铜管在制作四通阀时，需要锯切、车削、冲孔等机加工，因此对公差精度要求很高。

But it in 10"8mol/L-10"mol/L inhibited gastrin secretion .whereas it promoted somatostatin secretion of duodenum in vitro. GnRH-A did not effect significantly gastrin and somatostatin secretion of stomach in vitro.These results suggested that GnRH-A may integrate with GnRH receptor and restrain directely gastric acid secretion in parietal cell.

综上所述，我们认为胃腔内的Gn尺H类似物可能首先和壁细胞上GnRE受体结合，直接抑制壁细胞胃酸的分泌，由于胃酸分泌减少反馈性地刺激胃泌素细胞，促进其合成及分泌胃泌素，胃酸分泌减少同时也反馈性的抑制生长抑素的释放，反馈性地抑制胃肠壁内EC细胞分泌5一HT。

The force on the jet pipe in the hole jetted is analyzed, and it is indicated that the resistance on the jet pipe is the main factor influencing the feeding of jet pipe.
