A large range of IRZ and intense fluctuating velocity area around the boundary of IRZ is measured and thought to be important to keep the excellent ignition and combustion characters of the new kind swirl burner. Together with temperature trace method, different structure and operation parameter of the burner are studied in this paper about their effects on turbulent and mixing characters of swirling jet. The structure variation includes different blade angle, use of central gear shape baffle, variable outer length and angle of lean primary air outlet, use of wedge outlet of lean primary air.

采用上述两种测量方法并结合热质比拟温度示踪的方法，本文对径向浓淡旋流煤粉燃烧器喷口结构和气流流动参数的变化对旋流流场的流动、混合、湍流脉动特性的影响进行了深入研究，研究了旋流叶片倾角大小、中心齿型扩锥、淡一次风扩口外伸长度和扩角的变化、淡一次风楔形扩口、直流二次风扩口角度的变化对出口旋转射流流动特性的影响，研究了一次风率和旋流二次风率运行参数变化的影响规律。

Indeed, Marquez defended the IBF bantamweight title seven times and won the world junior featherweight title in his first meeting with Vazquez. Vazquez made two defenses of the IBF super bantam title, won the world junior featherweight title, defended it twice and lost it to Marquez in their first fight.

事实上，在小马奎兹首战瓦兹奎兹并获得WBC次羽量级头衔之前，他已经7次成功卫冕了IBF雏量级头衔；瓦兹奎兹则是两次成功卫冕IBF超雏量级头衔，再获得WBC次羽量级头衔并成功卫冕两次，之后输给小马奎兹。

In this paper, three robust estimators: robust best invariant quadratic unbiased estimator, robust minimum norm quadratic unbiased estimator and robust Helmert estimator have been designed. Finally, this paper states that these three classical estimators are particular cases of the RBIQUE.

导出了稳健最优不变二次无偏估计、稳健最小范数二次无偏估计、稳健Helmert估计，并说明了最优不变二次无偏估计、最小范数二次无偏估计以及Helmert估计等均是稳健最优不变二次无偏估计的特例。

An image conic can be the projection of either a planar conic or silhouette of a conicoid. We show that at least three images, taken from the same position with different camera orientations, of two planar conics, or two conicoids, or one conic and one conicoid, are needed for the calibration, and a closed-form solution can be obtained. Our new conic based calibration technique requires no knowledge of camera's orientations, and relies solely on image correspondences.

在不同的方位拍摄三幅或三幅以上图像，每幅图像至少包含两个空间平面二次曲线、或两个二次曲面、或一个平面二次曲线与一个二次曲面的投影，利用图像之间的二次曲线对应关系，可以确定摄像机的内参数矩阵，同时可以获得摄像机不同方位之间的旋转矩阵。

Results In 136 patients, a total of 72cases sputum culture positive, the positive rate of 52.9% sputum culture for three consecutive single bacteria were 16 cases, the positive rate of 11.8%.16 patients sputum results were:hemolytic streptococcus 6 cases, 4cases of Pseudomonas aeruginosa , Klebsiella pneumoniae in 2 cases and gas production Bacillus 2 cases , Enterobacter Bacillus 2 cases, 136 patients with 386 cases sputum culture times , 106 times positive(27.5%), and consecutive three or more times a train 4 the same bacteria ,only 42 cases(10.8%); the same single-64 cases sputum culture , which amounts to 16.6%.

结果 在136例患者，共72例痰培养阳性，阳性率52.9%，痰培养连续3次为单一细菌者为16例，阳性率为11.8%。16例患者痰菌结果分别为：溶血性链球菌6例，绿脓杆菌4例，克雷伯氏杆菌2例，产气杆菌2例，阴沟杆菌2例，136例患者386例次痰菌培养，106例次阳性（27.5%），而连续3次以上培养为相同一细菌，仅为42例次（10.8%）；非相同单一痰菌培养64例次，占16.6%。

Some primary metering grooves with different curvature radiuses and geometrical dimensions were designed,and the hydraulic characteristics of them were all tested Based on the experiment results, different flow characteristics of them were obtained The great differences between the experimental results and the conventional theoretical predictions were found by the comparison between them Under the condition of this experiment, the critical Reynolds is 1000～1200, and is diminished as the decrease of th...

为了在设计层板发汗冷却推力室时选择合适的一次调节通道，对不同曲率半径、不同几何尺寸的一次调节通道进行了流阻试验，得出了不同几何尺寸的一次调节通道的流动特性。试验结果与经典的层流理论计算结果之间存在较大的差异。试验表明，一次调节通道的临界雷诺数随曲率半径的减小而减小，摩阻系数随曲率半径的减小而增加，并得出了相应条件下的一次调节通道摩阻系数的修正关系式，在层流范围内能较好地反映一次调节通道的流阻特性

The contents of chlorophyll and the catalase activity of celery were increased 19.06%, 6.52% in the once top-dressing treatment with 300ml biogas slurry (A1I) than that applied chemical fertilizer (A1I).

其中一次施用300ml沼液的追肥处理(A1I)比化肥处理（B1I）对芹菜的叶绿素含量、过氧化氢酶活性分别提高了19.06%、6.52%；一次施用900ml沼液的追肥处理(A2I)比化肥处理（B2I）对芹菜的VC含量、还原糖含量分别提高了9.07%、51.31%，硝酸盐含量下降了31.65%；且施用沼液时一次施用与分次施用对芹菜的品质、产量无显著影响，化肥的分次施用与化肥的一次施用相比，芹菜的硝酸盐含量显著降低。
