输入8位电话号码，自动为每位数字生成对应的DTMF信号，送出双频声音(Enter the eight telephone number, automatically generates the corresponding DTMF signal for each digit, dual-frequency sounds sent)

地球物理勘探中重力资料解释的主要目的是由地表观测值推断地下可能存在的密度分布。众所周知,任何一组重力数据都可能由无数个密度分布所引起。即使假设了重力异常是由具有均匀密度差的单一地质体产生的,也得不出唯一的解(Gravity geophysical exploration data interpretation main purpose is inferred from surface observations may exist underground density distribution. Is known, any set of data may be provided by gravity density caused numerous. Even assuming that the gravity anomaly is determined by having a uniform density difference arising from a single geological body, they have no unique solution)

对于一阶系统辨识，分别采用LMS、RLS、仿射投影算法来估计参数(For a first-order system identification, respectively, using LMS, RLS, affine projection algorithm to estimate the parameters)
