选取时间 meaning in English
access time
Examples
- Thus this paper puts forward the dynamic time series period analysis and prediction model . it combines the basic principle of the stepwise regression period analysis to the multiplayer - transfer method . it can not only effectively select every latent period of a time series , but also take advantage of the selected latent periods to make a long - term prediction
因此本文提出了动态时间序列周期分析预测模型，它是将多层递阶方法与逐步回归周期分析的基本原理相结合，使之既可以有效地选取时间序列的各个隐含周期，也可以利用所选取的隐含周期作较长的时间预测。 - In the real estate investment early warning system , this paper firstly analysis the time difference correlation about the real estate investment index and other indexes . then some leading indexes are selected to act as the basis indexes system of the whole early warning system
在房地产投资预警信号系统设计中，首先以房地产投资为基本指标，分析出其他有关房地产业指标与房地产投资指标之间的时滞关系，然后根据一定原则适当地选取时间关系上处于先行的指标（也叫先兆指标）作为系统分析的基础指标体系。 - Hence this method can improve accuracy and efficiency of the calculation . c . based on these work upwards , an adaptively wavelet precise time - invariant integration method was proposed in this paper . in this method , an adaptive multilevel interpolation wavelet collocation method for partial difference equations ( pdes ) was conducted , in which the time complexity is less than oleg v ' s method , and then the adaptive precise integration method was combined with , so that in this method the adaptively discretes both in time domain and physical domain were realized
该方法将外推法引入求解结构动力方程的精细时程积分法中，从而使该方法在求解非线性动力方程中可以自适应选取时间步长；需要指出的是，由于考虑了矩阵指数精细算法和外推法算法在时间离散方法上的一致性，在外推过程中，计算工作量基本没有增加；因此，两种方法的结合有效提高了算法的效率和精度。
