調查結果顯示， 19個採集的水樣中有6個含有裂解織線藻的噬藻體，而且水樣未經濃縮即能裂解宿主，說明噬藻體在淡水中分佈較廣泛，裂解性也較強；混合培養條件下的研究結果表明，噬藻體裂解宿主后，細菌數量快速增加，而當培養系統中有非宿主藻類存在時，細菌的增殖則受到非宿主藻的抑制，說明噬藻體可以顯著改變系統中微生物的種群結構。Modbus transducer is the key device in the system and is used to offer power supply of pressure and temperature sensor, to collect signal, to linearizate and compensate temperature, to calculate density, volume and mass, to transmit data to modbus network, and display the data. so the modbus transducer is a multi - parament measurement, intelligent control device which can manage multi - signal
