反向时间
Examples
- The same computational code was also used to reconstruct the reverse time image
相同的计算机程式并用以推求空间逆时影像。 - In this study , we applied the reversibility of elastic wave to a discussion of the reverse time propagation of wave equation
摘要本文应用波动方程式的可逆性讨论弹性波的逆时影像重建。 - Although direct waves are much stronger than scattering wavefields , the imaging of the underground anomaly is still well reconstructed from the reverse time process
即使利用含有非常明显直接波信号的历时记录亦可有效的重建地下散射体的影像。 - Thirdly , it simulated the pumping circuit & dividing circuit with the widely used software matlab / simulink . the displacement of the rod piston and the impact of hydraulic are analyzed in the different input flow ( frequency of pump ) and different reversing time . it found out the cause of hydraulic impact ( one - to - one incorrespondence between the response time of dividing circuit and the operation time of rod piston ) , and gave some methods to weaken hydraulic impact . in the final part of the paper , the reliability of the theory analysis is further verified by the experiment of hydraulic system
首先在流变学原理的基础上，深入分析混凝土在输送管道内的流动状态，得出混凝土泵的负载特性方程；然后根据功率键合图的建模方法，建立泵送回路和分配回路的数学模型，并运用仿真软件matlab simulink对泵送和分配回路模型进行了仿真，分析了在不同的输入流量(泵送频率)和换向时间下，活塞杆的位移和系统的液压冲击情况，找到了引起液压冲击的根本原因(即分配回路的响应时间(固定值)与活塞杆的运动时间(变化值)不相匹配) ，并提出了相应的改进方法。
