Ms of class b can be connected with gprs and other gsm services and monitor their control channels at the same time . but only one service can be provide at the same time B类ms可以接入gprs和其他gsm服务，同时监控gprs和gsm服务的控制信道，但在某一时刻只能运行一种服务。
By arrangement of the control channels through which the hydraulic fluid flows from the discharge chamber into the oil reservoir , this allows any gas bubbles being released from the hydraulic fluid during the suction stroke to be expelled into the oil reservoir 通过液压油经控制通道由排出腔流入油槽的这种布置，使得任何在吸入冲程从液压油中释放出来的气泡都被排到油槽中。
