应用化学C4H12Si类四甲基硅结构的神经网络

用神经网络的反向传导原理模拟振动制作一个网络，让这个网络的结构与四甲基硅的结构相同。网络的收敛标准是单键两端的输出函数的差值的绝对值小于δ，

让δ等于0.5到1e-6的34个值。每个δ收敛199次取平均值。网络的输入等于原子序数/30.网络用一种只等值但并不耦合的方法运行，也就是共有17套独立的网络。

统计相对稳定的1e-4到1e-6的区间的数据，

	C-Si	C-H	C-H	C-H
C0	0.907371	0.617498	0.617552	0.617865
C1	0.907036	0.617715	0.617972	0.618017

C3	0.906007	0.617952	0.616975	0.616973
	0.906662	0.617782

可以明显的观察到只有C-Si键和C-H键两种键值，其中C-Si键值约为0.90662，C-H键的键值约为0.617782。这个现象很好的体现了一种结构上的对称性。
