Upon searching the closet , she finds an unplugged patch cable hanging from one of the patch panels and an empty hub port 检查配线房时，她发现从其中一个配线板上垂下一根被拔下的接线电缆以及一个空的集线器端口。
The tristate driver circuit that interfaces with the main distributing frame and the transmit / receive filters . the drivers and filters are part of the port grouping 与主配线板和发送接收滤波器接口的三态驱动电路。驱动器和滤波器都是端口分组的一部分。
At the same time , the mathematical models of the electric field and the flow field distribution were established from the theory of electrostatic enhancement of heat transfer . employed finite differential method and over - relaxation iteration method , according to certain boundary conditions in the wire - plate electrode space , the electric field and the flow field in the wire - plate space were numerically simulated under different initial velocities of r11 stream and different magnitudes of applied voltage . the calculation results agreed with theoretical analysis satisfactorily 同时从静电强化换热理论出发，建立了表征线板电极间的电场和流场分布的数学模型，并根据线-板电极间的边界条件，利用有限差分法和超松弛迭代法，分别就不同气流初速度和不同外施电压的情况下，对线-板空间的电场和流场进行了数值模拟，计算结果与理论分析基本一致。
