＜正＞ It is known that the quasi-rigid bodymode（QR mode）vibration is one of the mainsources for generating the residual vibration insettling operation and limiting the servo bandwidth,and is mainly caused by the stiffness of the pivot,themass and structure of the head actuator *** ballbearings inside the pivot determine the pivotstiffness,which in turn,determine the effectivestiffness of the head actuator *** this paper,the stiffness-related issues among ball bearings,pivot and head actuator assembly are studiedtheoretically and *** shows that thepivot effective radial stiffness depends not only onthe stiffness of the ball bearing but also on theconnection method used to attach the pivot to thehead actuator *** is also shown from themeasurement and analysis that the resonancefrequency of the QR mode,determined by the pivoteffective radial stiffness and inherent properties ofthe head actuator arm,can be moved to a higherfrequency by using a more rigid pivot and a morestiff joint.

Two cruises were conducted in January and July 1986 in the changjiang (Yangtse River) Estuary and its adjacent East china Sea (30°45′ -32°00′N,121°00′-124°00′E). Direct epifluorescence counts of planktonic bacteria and determinations of ATP concentrations were made. Subsamples were taken for measurement of oxygen consumption rates and chlorophyll *** and ATP concentrations were higher in summer than in winter, highest in the river and the river mouth, and gradually lower offshore. The bacteria number was correlated positively with suspended matter, nitrates and oxygen consumption rates, and negatively with *** winter bacteria were the main contributors of ATP and the main consumers of dissolved oxygen in the whole studied area. In summer two maxima of ATP were found along the salinity gradient. The first one which coincided with the peak of turbidity near the river mouth was attributed to bacte -ria, and the second which occurred in the waters with a salinity range
