闭合

The power dissipated in the coil of the reed relay may cause the temperature to increase for several minutes after it is energized, so it is important to make low voltage measurements within a few seconds after contact closure.

簧片继电器的线圈被加激励之后几分钟，其消耗的功率会导致温度上升，因此对于低电压测量来说，在触点闭合之后的数秒内完成测量是非常重要的。

The temperature collected by 18 B20 is detected by single chip computer,according to high and low temperature,single chip computer P2.7-pin output high level or low level to control relay whether there is current in the coil through,according to the coil power relay,normally open contact is closed,no current passing,often a disconnect to maintain contacts so as to achieve the automatic control from the fans stopped.

利用单片机检测18B20采集的温度，根据温度高低，单片机的P2.7脚输出高电平或者低电平，来控制继电器线圈中能否有电流经过，根据继电器线圈通电时，常开触点闭合，没电流经过时，常开触点保持断开，从而实现自动控制电风扇的起停。

The model can reflect the multi-sets feature of the rock masses in practice, consider the influence of the joint orientation and strength to the rock masses deformation feature, and simulate the simultaneous sliding, tension and close behaviors of the multi-sets jointed rock masses extending the joint surface, and reflect the plastic deformation induced the rotation of the principle stress axes. The result can be extended to fractured rock masses with arbitrary set joints.
