1·To the poor stationarity of bent axle and the big vibration after remodeling, we redesign the bent axle.
针对改型后两缸机平稳性差、振动大的特点，我们对曲轴做了重新设计。
2·In this paper, we discuss the stationarity and invertibility of a bilinear model.
本文主要讨论双线性时间序列模型的平稳性与可逆性。
3·In actual testing, magnetic memory signal belongs to random signal without stationarity, adjusting adopting wavelet technique to analyze magnetic memory signal.
在实际检测中，磁记忆信号属于随机信号、不具有平稳性，宜采用小波技术分析磁记忆信号。
4·Main factors influencing precision of fractal dimension computation include number of data, distribution of data, stationarity of data, no scale area.
研究表明影响分维估计精度的主要因素有四种：数据点数、数据概率分布、数据平稳性、无标度区。
5·Based on the stationarity test of time alignment, it can be determined that there is no cointegration between foreign exchange earnings from tourism and economic growth.
依据时间序列的平稳性检验可以判定：旅游外汇收入和经济增长两时间序列之间应不是协整的。
