Nobody's supposed to talk in the temples, but these are teenagers, so there's a constant chatter going on all the time as we're working. 寺院内禁止说话,可是他们都是十几岁的青少年,因此我们干活儿的时候经常有人聊天聊个不停。
We expect the din of the cloud-related chatter to turn into a real roar by this time next year. 我们期望云相关的喋喋不休的喧闹在明年的这个时候变成真正的咆哮。
Make sure you arrive just a little late, smile and chatter happily, and make one glass of bad wine last a long time. 你要保证让自己略晚到一小会儿,席间要保持微笑,愉快地与人闲聊,手中那杯劣质酒要喝上很长时间。
Characteristics of Surface Grinding Chatter On Frequency Domain and Time Domain 平面磨削颤振的频域和时域特征
A Study of the Chatter in Time-Varying Metal Cutting 时变金属切削过程颤振的研究
It proposes a new method of characteristic extracting for chatter signal in time domain based on power analysis and provides a new sampling model to the characteristic extracting of cutting chatter. 文章还提出了从时域基于功率分析对颤振信号进行特征提取的新方法,为切削颤振的特征提取提供了新的模式样本。
Grinding chatter signals are analyzed experimentally. It is found that in the grinding chatter signals, beat wave phenomenon in the time domain and sidebands phenomenon in the frequency domain are both resulted from grinding wheel unbalance. 对磨削颤振信号进行了实验分析,证明了由于砂轮回转不平衡的影响,造成磨削颤振信号在时域上的拍波和频域上的边频带现象。
Fractal theory has application in mill chatter analysis in this paper. And it also focuses on the study of parameters selection in correlation dimension of fractal dimension, such as delay time, embedding dimension, no-scale interval, etc. 本文重点研究了分形维数的参数选取,如延迟时间、嵌入维数、无标度区间的选取等,对轧机异常振动信号进行了关联维数的计算研究。
Simulation of cutting chatter signal in time domain is accomplished through MATLAB/ SIMULINK, and the correctness of the theory analysis conclusion is proved. 同时利用MATLAB/SIMULINK对切削颤振进行了时域仿真,表明了理论分析结论的正确性。
