  3. The condition of profiles in outer station did n ' t change much in spring cruise, but showed more variable in near - shore stations when observed in different time. fluorescent characteristic per cell can be obtained by flowcytometric analysis. based on fluorescence data of synechococcus of all stations, two distinctly pigment - containing cell types coexisting can be found in some stations of east china sea, which located in all depth of p3, mixlayer of e7, 40 - meter depth of e6 of autumn cruise and in mixlayer of p2 of spring cruise

    通過對流式細胞測量的細胞熒光結果來看,在秋季的p3 、 e7整個混合層、 e6站40米層,春季的p2站均發現有兩群不同色素含量的聚藻( high一pe和low一pe )共存現象,極有可能分別屬于不同品系,春季共存站位位置比秋季更靠外,明在秋季p3 、 e7等站位的共存是季節性現象,可能與此季節黑潮次沿陸架坡涌升入侵到中陸架有關,團的運動及混合使從外海遷移而來的high一pe與近岸的low一pe得以共存,在春季,由於長江沖淡的日漸強盛,在中陸架區的共存區域有所外移。
  4.

  5. Based on physical experiments, establishing mathematical model, carrying on theoretical calculations, and contrasting experimental results with theoretical ones, it turned out that under the same initiate flow rate, the quicker the closing of the ball valve, the longer the stable time when the liquid gets to vaporizing pressure, and the bigger the water hammer in water interception collision ; under the same closing velocities of the ball valve, the larger the initiate flow rate, the longer the stable time when the liquid gets to vaporizing preesure, and the bigger the water hammer in water interception collision

    在試驗研究的基礎上,建立了含氣錘數學模型,進行數值算,並與試驗結果進行了比較,結果明,在管道初始流量相同的情況下,閥關閉速度越快,液體達到汽化壓力凡穩定的間越長,彌合錘壓力也越大;在閥關閉速度相同的情況下,管道初始流量越大,液體達到汽化壓力凡穩定的間越長,彌合錘壓力也越大。
  6. By driving expressions and using the method in numerical integration, the results of numerical calculations are analyzed, discussed and contrasted with different conditions, and they showed that there are evident differences in the mean attenuation, scattering, and back scattering cross sections of oblate spheroid particles when the variance is so small that it is near to zero namely it is the same as the rotatory axes are parallel with one direction and when h - polarized and v - polarized incident waves happened. these differences are depended on the relative differences in the average orientation of rotatory axes and the polarized directions of incident wave
