節涌流 的英文怎麼說
中文拼音 [jiéyǒngliú]
節涌流
英文
slug flow-
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
通過對流式細胞計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球藻（ 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時更靠外，表明在秋季p3 、 e7等站位的共存是季節性現象，可能與此季節黑潮次表層水沿陸架坡涌升入侵到中陸架有關，水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，由於長江沖淡水的日漸強盛，在中陸架區的共存區域有所外移。The chip is mainly applied to the portable electronic products with the following features : 2. 7v to 5. 5v input voltage range ; the 1mhz fixed frequency ; - 40 to + 85 operating temperature ; two digital inputs control on / off and select amongst three levels of brightness ; thermal shutdown and under voltage shutdown protection, low 0. 1 a shutdown current ; soft - start limits inrush current
