1、可以有效地避免電纜連接中出現(xiàn)的問(wèn)題,而PDA作為主機(jī)可以更加迅速地對(duì)譜數(shù)據(jù)進(jìn)行處理和分析。對(duì)于一些核測(cè)量現(xiàn)場(chǎng),有時(shí)存在電磁干擾、強(qiáng)輻射以及強(qiáng)放射性等問(wèn)題,借助藍(lán)牙技術(shù),工作人員可以通過(guò)PDA遠(yuǎn)程遙控儀器,從而避免現(xiàn)場(chǎng)測(cè)量中放射源對(duì)人體的輻射和吸人性的內(nèi)照射,這使7能譜儀有著良好的實(shí)用價(jià)值和應(yīng)用前景。通過(guò)測(cè)試和實(shí)際使用,證明本系統(tǒng)運(yùn)行穩(wěn)定,使用方便,測(cè)量準(zhǔn)確。參考文獻(xiàn):[1]馬建倉(cāng),羅亞軍,趙玉亭.藍(lán)牙核心技術(shù)及應(yīng)用[M].北京;科學(xué)出版社。2003.[2]K哪}er,1鋤ley.hnp∞VedPerf0恤踟魄inGerInmIli啪Detectc玎l(xiāng);a加缸埔Sp∞缸13me
