On the basis of the hardware of the detect system which uses ~ ( 252 ) c _ f - source - driven neutron noise analysis method , i designed the emulation platform of the apsd estimate , as an important part of the whole detect system 在~ ( 252 ) c _ f源驅動噪聲分析法的測試系統(tǒng)硬件平臺基礎上,本文首先設計和實現(xiàn)了功率譜估計這一部分的仿真硬件平臺。
~ ( 252 ) c _ f - source - driven neutron noise analysis method is a way of measuring and analyzing the reactivity of reactor or subcritical reactor , which detects subcritical neutron multiplication factor , prompt neutron decay constant , and so on ~ ( 252 ) c _ f源驅動噪聲分析法是一種測量、分析反應堆和次臨界系統(tǒng)的快速反應性的方法,可作為臨界安全的瞬時檢測方法。
With a view to time - varying characteristic of the vibration signal measured on triplex reciprocating pump , an approach on the waveform feature extraction which reflects the various conditions of reciprocating pump with nonlinear wavelet de - noising analysis method is presented 針對三缸往復泵測量信號非平穩(wěn)時變特點,研究了用小波消噪方法提取反映往復泵動力端狀態(tài)的振動波形特征。
