证明了在任何组合电路中，只需两个测试码便能测试出所有可能的初级输入与输出端之间的短路故障。

It is shown that any feedback bridging faults between primary inputs and the primary output in any general combinational networks can be betected by using only two test patterns.

只有A/C扩大器上的电压是来自输入端的正确电压时，初级输出（即A/C压缩机继电器）才会被激活开启。

It is only when the correct voltages are applied to the A/C amplifier from the key inputs that the primary output (the A/C compressor relay) will be energised.

结果提示，躯体与内脏输入可通过分叉初级传入，在同一个A型脊神经节神经元上会聚。

These results indicate that somatic and visceral input may converge on single type a spinal ganglion neurons via dichotomizing primary afferents.
