deterministic signal meaning in English

确定性信号
确知信号

We find that all the results are quite different between each original emg and its ten surrogate data , i . e . emg is not a linear random noise , but a nonlinear deterministic signal ( though it does not like a low dimensional chaos )
也就是说，肌电不是线性随机的噪声，而是非线性的确定性信号(尽管它并不象是低维混沌) 。
Time domain noise is simulated by the mathematical pseudo uniform or normal random variable and coupled to deterministic signals such as rectangular ( rect ) , triangular ( tria ) , unit step exponential ( uexp ) , even exponential ( eexp ) , or gaussian ( gauss ) pulse voltages in finite number of time samples in finite time period
用数学类真均匀或常态随机变数模拟时域杂讯，与定然时域讯号如，方形、三角、指数递减、或高斯等电压脉波在有限时域?围之有限个时域取样结合。
