1. study of rf direct bandpass sampling structure of software radio amp; amp; its use
   射頻直接帶通采樣軟件無(wú)線電結(jié)構(gòu)分析及其應(yīng)用
2. although reducer can avoid step sense and oscillation partly, the strap transmission will influence orientation precision ( it is key norm to the small metallographic sample cutting machine ), so plan to use step motor to drive the screw directly, the step motor at low velocity, which is not drived by the subdividing drive system, will have obvious oscillation and noise that would influence the cutting function, the usage life and sample structure
   由于步進(jìn)電機(jī)是通過(guò)皮帶輪減速來(lái)驅(qū)動(dòng)絲杠，進(jìn)而帶動(dòng)砂輪片前進(jìn)和后退，雖然減速能部分消除步進(jìn)感和振動(dòng)，但皮帶傳動(dòng)會(huì)影響定位精度，定位精度對(duì)精密切割機(jī)十分關(guān)鍵的技術(shù)指標(biāo)。采用步進(jìn)電機(jī)直接驅(qū)動(dòng)絲杠，未經(jīng)細(xì)分驅(qū)動(dòng)的步進(jìn)電機(jī)在低速運(yùn)行時(shí)，有明顯的步進(jìn)感、振動(dòng)和噪聲，從而對(duì)切割的性能、砂輪片的使用壽命、試樣的組織結(jié)構(gòu)產(chǎn)生較大的影響。
3. It's difficult to find sample structure in a sentence. 用sample structure造句挺難的
