Results The bronchi stricture can be seen at lobar bronchus or segmental bronchus and the bronchial walls were thickened. No mass and opposite "S" sign can be found in all the cases. Among them,centripetal stricture can be found in 6 cases, and eccentric stricture in 11 cases. Bronchi stricture with obstructive atelectasis in 12 cases. In which "Air bronchogram" can be found in 9 cases. Bronchi stricture with pleural effusion in 8 cases. With intrabronchial polypoid shadows in 5 cases. With active pulmonary TB in 9 cases.

The effects of feeding frequencies(1, 2, 3 and 4 times per day) on the growth of Sparus macrocephalus were studied in a 40 d growth trial under the condition of 26.8~24.5℃, 26.0~27.0 salinities for determining the optimum feeding frequency. Identical diet was selected for the mature and seedling of Sparus macrocephalus in the aquiculture system.

接着分别从磨矿细度、矿浆浓度、药剂制度、搅拌速度和充气量等方面，对中煤的泡沫浮选进行了条件择优试验，并取得了各因素的最佳数量范围。

Based on the noise theory and experi mentation ,the author founded the onli ne method to test current noise , validated the relation bet ween te mperature ,aperture and pressure with current noise .This paper firstly analyzed gener— ati ng mechanis mof discharge niose ,studied the measure and factor of discharge niose ,i ndicated an effective method for degradi ng the discharge noise ,which pro moted the performance of laser gyro fro m0.01°／h to 0.001°／h.

文中以氦氖气体激光器的噪声特性理论为指导，以试验研究为基础，建立了在线噪声电流测试方法，通过试验验证了温度、腔体毛细孔径、谐振腔充气气压等参数与放电噪声的关系，首次提出了放电噪声产生的机理，分析了电流噪声的检测方法及影响因素，给出了减小和抑制放电噪声的有效方法，使得激光陀螺的性能由0.01°／h 提高到0.001°／h。

METHODS: Patients undergoing routine, nonemergent cardiac surgerywere randomly assigned to routine thermal management (fluidwarming and passive insulation, n = 30) or routine managementsupplemented by an active underbody forced-air system ( n = 30;Arizant Healthcare Model 635, Eden Prairie, MN).

常规、非急症心脏外科手术患者随机分为两组：常规体温保护组（输液加温以及消极隔离， n=30）和常规保温联合使用积极的衬垫式充气加温系统（ n=30 Arizant Healthcare Model 635， Eden Prairie，明尼苏达州）。

Our findings were that artificial pneumatic muscle forces in our orthosis were largely dictated by the forcelength relationship.
