A new infinite gas-lubiicated journal bearing with active controlled restrictor is proposed in order to remedy the defects of several existing infinite stiffness at abroad in construction, manufacture and adjusting, which combining surface-restriction with active controlled restriction, make the static and dynamic effect both better.

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.

结果 6例（100%）患者多层ct表现为双肺散在分布毛玻璃样高密度影，与周围组织分界清楚，呈地图样表现，病理学活检见肺泡腔内蛋白质样物质沉积，其中4例（66%）小叶间隔增厚，可见间隔水肿及淋巴细胞浸润，hrct呈铺路石样表现。所有病例未见纵隔、肺门淋巴结肿大。

Objective To evaluate retroperitoneal laparoscopic adrenalectomy for benign adrenal tumors.

目的 评价经腹膜后腔行腹腔镜肾上腺肿瘤切除术的临床价值。

Simultaneous measurement of CORB and COTD were performed in following situations:(1)cardiac output was varied by manipulating inotropic drugs(adrenine, dobutamine, dopamine, verapamil);(2)under six different ventilatory settings:①volume controlled ventilation with tidal volume of 12ml/kg(VCV, VT 12ml/kg);②volume controlled ventilation with tidal volume of 6ml/kg(VCV, VT 6ml/kg);③pressure controlled ventilation with tidal volume of 12ml/kg(PCV, VT 12ml/kg);④pressure controlled ventilation with tidal volume of 6ml/kg(PCV, VT 6ml/kg);⑤volume controlled ventilation with high positive end-expiratory pressure.
