突变点 meaning in English
abrupt junction
catastrophe point
mutation point
Examples
- Using the wavelet de - noising techique , the nosing signals are filtered out and the signals of sharp transition are located
利用小波消噪技术可以滤除信号噪声，提取出信号的突变点。 - For example , the jump points that 8 years converging upon 1 year are in 1958 , 1970 , 1981 and 1998
存在不同尺度周期的突变，如8a尺度辐合到1a尺度的突变点位置为1958 、 1970 、 1981 、 1998年。 - The new denoising method not only preserves signal ' s original features , but also has stronger ability to remove noise
用该方法去噪既能很好地保持信号突变点的原有特性，又具有较强的去噪能力。 - Because of high intelligence of gmdh modeling , the location and the break kind of break - point can be determined automatically , then the optimal model can be obtained
由于gmdh建模的高度智能化,因此能够自动选择结构突变点的位置和突变类型,准确地得到最优的结构突变点。 - Combined with the graph correlating the first resonance frequency with driving point location , the method localizes the crack by monitoring a jump in the graph
结合裂纹梁第一阶谐振频率与驱动点位置关系曲线，利用曲线上出现的突变点，准确地识别了梁的损伤状态和裂纹损伤位置。
