csn的音标

The colored silica nanoparticles ( CSN) were synthesized by reverse microemulsion method. The morphology and degree of dispersion of CSN were characterized by SEM. The agglutination test was used to characterize the detection effect of S. pullorum and S. gallinarum.

利用第一部分所讨论的反相微乳法首先制备CSN，用扫描电镜表征其形貌特征和分散程度，通过凝集现象表征ICSN对鸡白痢鸡伤寒沙门氏菌的检测效果。

CSN 3102 follow that A 319 and maintain visual separation, expect visual approach runway 20 R , report runway in sight.

跟着A319,保持目视间隔, 预计目视进近跑道20R,目视跑道报告.

CSN 3102 descend to 900 m, cleared visual approach runway 20 R, follow that A 319 5 miles ahead, same runway.

下到900米, 可以目视进近跑道20R, 跟着同跑道前方5海里的A319进近.
