Once a call session is defined , incremental parameter changes can be made quickly . call files and individual call attributes can easily be modified or fine tuned using a simple , familiar spreadsheet type interface 话音和视频呼叫采用各自的呼叫控制和参数选择菜单进行编程。呼叫文件和各个呼叫特性可以方便地采用简单熟悉的电子表格型界面修改或调整。
The results show that the resonator parameters changed significantly due to thermal deformation of the mirrors , and the central intensities of the far fields reduced obviously with thermal deformation increase 计算结果表明:在激光束辐照的开始阶段,温升场主要集中在激光束辐照的中心区域内,在整个镜面上远未拉平,由此引起的厚度方向温升分布也是如此,很不均匀。
The needed time and energy for designing and compiling them are great . especially it took a lot of energy and time to explore and realize the communication , the system state control and the parameter changing on - line , ect 本系统工作量很大,特别是通信模块、系统控制模块上及参数在线修改等模块上,花费了大量的时间与精力进行深入的研究,设计出了较高质量的应用程序。
The results indicate that the fractal dimensions are obviously different when the welding parameters changed and that the box counting dimension as the characteristic parameter can effectively reflect the quality of nuggets 试验与计算结果对比表明:对不同点焊质量下的电压参数进行检测与盒维数计算,其结果明显不同,这说明以盒维数作为特征量能够有效反映点焊质量的变化。
Based on single well process , the influence of reservoir parameter changes , such as permeability , reservoir thickness , average formation pressure , deformation factors on well productivity were studied by using the model under the depressure condition 最后,以单井为对象,应用建立的数学模型研究了降压开发条件下,渗透率、油层厚度、平均地层压力、形变因子等储层参数变化时对油井产能的影响规律。
