The major technical parameters for ultrasonic test for waveform pictures of delamination and crack are presented as follows : detecting way : single probe ( uni-emissing, constant intensity ); 得出了实验条件下PDC分层、裂纹缺陷的超声波测试波形图和主要技术参数如下。工作方式:单探头(单一发射,强度不变);
With the constant intensity of the bivariate structure, agriculture influences other industries, which has become the shackles to other relative industry development. 随着二元结构的不断加剧,农业对其他产业的影响也越来越大,已经成为其他相关产业发展的桎梏。
The paper discusses the construction of staging process and provides the probability model of the staging process by the way of convolution. The application of models is demonstrated with constant intensity μ j. 本文讨论阶段化过程模型的构造,以卷积方式导出阶段化过程分析的概率模型,并以给定的强度因子μj,用此模型作了演示计算。
OFDM signals can help to overcome the dispersion effect and PSK signals can suppress the non-linear effect effectively because of the constant intensity of PSK signals. OFDM信号能帮助克服色散的影响,而PSK信号强度恒定,可以有效抑制非线性效应。
The creep deformation increases with the increasing of overload ratio and constant stress intensity factor. 室温蠕变量的大小与过载比和恒载应力强度因子成单调递增关系;
