指定频率 meaning in Chinese
assigned frequency
designated frequency
Examples
- Plays the sound of a beep of a specified frequency and duration through the console speaker
通过控制台扬声器播放具有指定频率和持续时间的提示音。 - However , when one may optimize structure with a specially designated frequency , the ones lower than the frequency should be avoided to save time and to improve computing precision
对于指定频率的动力拓扑优化问题，如果能够避免求解指定频率以前的频率而直接对指定频率进行计算，将无疑可以提高计算效率和计算精度。 - The prestress and harmonic response analysis method is used to study the unbalance response of a turbo - generator rotor and the displacement - frequency curve at a point of the rotor as well as the sress and strain at an appointed frequency are provided
摘要利用预应力及谐响应分析的方法研究了转子的不平衡响应，得出在某频率范围内，转子在指定点处位移对频率的响应曲线以及在指定频率处，整个转子上的应力、应变响应的影响等。 - The catv charge and control system is mainly composed of the management software 、 the header data modulator and the terminal charge and control equipment . i am responsible for design catv charge and control equipment and test system . the header data modulator is used to encrypt the control single from computer and transmit it into the appointed frequency . the terminal charge and control equipment demodulate out the control single from data modulator and transmit it to the addressing control part , where the demodulated fsk single is received and well - handled by the cpu unit , decode the unauthorized signals and deliver it to the shut point , shut point make use of capability of wideband anf characteristic of shut , then the signal of illegal customer will be turn off and vice versa , the legal customer can receive the normal signal
前端数据调制器完成对计算机输出的控制信号加密处理,将指令码载送到一指定频率点。终端收费控制器解调出控制信号,送至单片机寻址控制部分。单片机寻址控制部分接收经fsk数据解调器送来的信号,送入cpu单元后,解出不授权信号,然后向关断部分送入信号,关断部分利用pin二极管的宽带工作能力以及关断特性,实现对非授权用户或者非法用户的信号关断,使之不能正常收视,缴费用户进行开通正常收视,达到控制用户通道的管理。 - Based on apdl , the design language of finite element analysis software ansys , and visual c + + , the software on acoustics design of underwater cylindrical shell structure is developed . when input parameter of the cylindrical shell in the interface redeveloped in this paper , the software execute the batch file of apdl in the vc process to establish the finite element modal and carry out the analysis , the analysis result and the vibration mode can also be displayed . furthermore , the software has been developed to process the acoustics optimization design of the finite cylindrical shell with stiffener in appointed frequency range
本论文从便于工程实际应用出发，对使用有限元分析软件进行二次开发以方便结构振动分析及改进结构设计的方法和过程进行了研究，在此基础上对水下航行器圆柱壳体的结构声学特性进行了分析，在指定频率区间，对结构以振动辐射声功率级为目标函数进行了部分参数的结构优化设计，与此同时，为了方便有限元分析软件的使用和简化设计过程中大量重复的工作，利用ansys提供的参数化设计语言apdl ( ansysparametricdesignlanguage )结合vc对有限元软件ansys进行了二次开发，形成了一体化的水下圆柱壳体结构声学设计软件。
