That displacement is measured with a laser beam to create a series of 2-d images of the sample, which are combined to generate a 3-d image.

然后用一束激光来测量这个摆动的位移，并由此生成一系列此样本的二维影像，再由这个生成其三维影像。

Thus, the chaotic analytic method is set up for the prediction of the measured displacement time series of rock mass engineering.

据此，建立了岩体工程位移观测数据的混沌预测方法。
