心电信号R波检测的函数，包括降采样，滤波，希尔伯特包络提取三个预处理步骤。其中R波根据阈值检测，相对不应期要根据具体信号适当调整.(ECG R-wave detection functions, including down-sampling , filtering, Hilbert envelope extracted three pretreatment steps. Wherein R wave detection based on a threshold , the relative refractory period should be adjusted according to the specific signal . )

An effective implicit time integration scheme was proposed for the fi nite element solution of nonlinear problems in structural dynamics. Various important attributes were demonstrated. In particular, it was shown that the scheme remains stable, without the use of adjustable parameters, when the commonly used trapezoidal rule results in unstable solutions. In this paper we focus on additional important attributes of the scheme, and specifi cally on showing that the procedure can also be effective in linear analyses. We give, in comparison to other methods, the spectral radius, period elongation, and amplitude decay of the scheme and study the solution of a simple ‘model problem’ with a very fl exible and stiff response.
