32.分散式控制系統的主控權為現場控制單元，而控制室內電腦的主要功能則為負責何種工作狀態？ (A)監督機艙內各控制迴路 (B)控制機艙內各控制迴路 (C)計算機艙內各控制迴路 (D)模擬機艙內各控制迴路

9.Blowers are used with many diesel engines to supply the air necessary for combustion to the engine’s cylinders. When the pressure of this air is increased above atmospheric pressure, referred to as supercharging, the power output of engine is increased. In addition, in a two-stroke engine the air supplied by the blower helps to purge the engine’s cylinders of exhaust gas. This is referred to as scavenging. Based on these descriptions, please specify the correct statement. (A)The scavenging and supercharging processes share identical purpose of increasing the static pressure in the intake pipes. (B)The use of blow for scavenging and supercharging is due to its characteristics of high-pressure and low volumetric flow rate. (C)The blower for marine application is always the centrifugal type as it offers the high speed characteristic. (D)The scavenging in a two-stroke engine assists to purge the engine’s exhaust gas which has beneficial effect for combustion.
