acceleration spectrum造句
例句與造句
- In chapter 3 , this paper recommended the methods of estimating the parameter of moving target using cyclostationary and analyzed the performance of this method firstly , and put forward a recursive method for estimating the parameter ( velocity , acceleration ) of moving target combining the characteristic of high - prf pulsed doppler radar . then , based on the resolution of doppler and acceleration , combining the characteristic of the doppler spectrun and acceleration spectrum , this paper put forward a new method for differentiating muli - target
然后，從彈載高重頻脈沖多普勒雷達(dá)的多普勒分辨率和加速度分辨率出發(fā)，結(jié)合不同編隊(duì)方式的多目標(biāo)回波信號(hào)的特點(diǎn)，分析了多目標(biāo)和單個(gè)目標(biāo)的回波信號(hào)的多普勒譜和加速度譜的特性，提出了一種基于一維多普勒像和一維加速度像的級(jí)次多目標(biāo)分辨算法。 - B ) relative velocity response spectrum ( sv ) and relative displacement response spectrum ( sd ) : the variation of velocity spectrum with depth is similar to that of acceleration spectrum . but the variation of displacement spectrum with depth is a little different to that of acceleration and velocity spectrum . that is , in strong earthquake , the variation of displacement spectrum and normalized spectrum in different depth is very small
( 2 )速度反應(yīng)譜( s 、 )和位移反應(yīng)譜( sd )沿深度變化的規(guī)律速度反應(yīng)譜沿深度變化的特點(diǎn)與加速度反應(yīng)譜基本相似;位移反應(yīng)譜沿深度變化的特點(diǎn)與加速度和速度反應(yīng)譜有較小差別，即強(qiáng)震時(shí)位移反應(yīng)譜和標(biāo)準(zhǔn)位移反應(yīng)譜沿深度的變化很小。 - Based on frequency - spectrum - transformation , this algorithm first changes acceleration spectrum into displacement spectrum , then calculates its amplitude , angular frequency and initial angle related to every displacement spectrum , finally sums up all the displacement components and forms the time course of the measured vibration
該方法采用頻譜轉(zhuǎn)換法，首先將加速度譜轉(zhuǎn)換成位移譜，再計(jì)算出位移譜中每個(gè)頻率分量對(duì)應(yīng)的幅值、圓頻率和初相角，最后對(duì)各位移分量進(jìn)行疊加得到振動(dòng)位移的時(shí)間歷程。 - It's difficult to find acceleration spectrum in a sentence. 用acceleration spectrum造句挺難的
