在使用分析天平進行稱量的過程中
，環境和物理因素會對稱量結果產生幹擾
，如溫度、樣品揮發
、吸濕
、磁力
、靜電等的幹擾。

（1）溫度的變化對分析天平的影響

如(ru)果(guo)在(zai)稱(cheng)量(liang)過(guo)程(cheng)中(zhong)發(fa)現(xian)顯(xian)示(shi)值(zhi)單(dan)方(fang)向(xiang)漂(piao)移(yi)，就(jiu)有(you)可(ke)能(neng)是(shi)溫(wen)度(du)變(bian)化(hua)所(suo)產(chan)生(sheng)的(de)影(ying)響(xiang)。若(ruo)樣(yang)品(pin)與(yu)周(zhou)圍(wei)環(huan)境(jing)之(zhi)間(jian)的(de)溫(wen)度(du)存(cun)在(zai)差(cha)異(yi)，則(ze)這(zhe)個(ge)溫(wen)度(du)差(cha)異(yi)就(jiu)會(hui)導(dao)致(zhi)沿(yan)稱(cheng)重(zhong)容(rong)器(qi)流(liu)動(dong)的(de)氣(qi)流(liu)。空(kong)氣(qi)沿(yan)著(zhe)容(rong)器(qi)外(wai)側(ce)流(liu)動(dong)產(chan)生(sheng)一(yi)個(ge)向(xiang)上(shang)的(de)作(zuo)用(yong)力(li)，這(zhe)個(ge)力(li)就(jiu)導(dao)致(zhi)稱(cheng)重(zhong)結(jie)果(guo)產(chan)生(sheng)錯(cuo)誤(wu)：樣(yang)品(pin)在(zai)動(dong)態(tai)浮(fu)力(li)作(zuo)用(yong)下(xia)，稱(cheng)得(de)的(de)重(zhong)量(liang)比(bi)實(shi)際(ji)要(yao)輕(qing)。這(zhe)個(ge)作(zuo)用(yong)直(zhi)到(dao)溫(wen)度(du)平(ping)衡(heng)形(xing)成(cheng)以(yi)後(hou)才(cai)會(hui)終(zhong)止(zhi)。當(dang)把(ba)樣(yang)品(pin)從(cong)幹(gan)燥(zao)爐(lu)或(huo)冰(bing)箱(xiang)中(zhong)取(qu)出(chu)以(yi)後(hou)，要(yao)等(deng)到(dao)樣(yang)品(pin)溫(wen)度(du)與(yu)實(shi)驗(yan)室(shi)或(huo)稱(cheng)量(liang)室(shi)溫(wen)度(du)一(yi)致(zhi)時(shi)才(cai)可(ke)以(yi)稱(cheng)量(liang)。樣(yang)品(pin)要(yao)放(fang)在(zai)表(biao)麵(mian)積(ji)盡(jin)可(ke)能(neng)小(xiao)的(de)去(qu)皮(pi)容(rong)器(qi)中(zhong)
，取(qu)放(fang)稱(cheng)量(liang)容(rong)器(qi)要(yao)使(shi)用(yong)鑷(nie)子(zi)夾(jia)取(qu)，而(er)不(bu)能(neng)將(jiang)手(shou)放(fang)入(ru)稱(cheng)量(liang)室(shi)中(zhong)。

（2）樣品吸濕或揮發對稱量結果的影響

如果在稱量的過程中顯示值單方向持續漂移
，則可能測量的是揮發性或吸濕性樣品。若樣品吸濕性較強
，則重量會增大；若ruo被bei測ce量liang樣yang品pin屬shu易yi揮hui發fa物wu質zhi
，則ze重zhong量liang會hui減jian小xiao。對dui於yu吸xi濕shi性xing或huo揮hui發fa性xing樣yang品pin可ke使shi用yong細xi頸jing容rong器qi，給gei容rong器qi加jia蓋gai或huo上shang塞sai
，使shi用yong清qing潔jie幹gan燥zao的de稱cheng重zhong容rong器qi並bing保bao持chi稱cheng盤pan上shang不bu粘zhan有you灰hui塵chen、汙染物及水滴。

（3）樣品或容器帶靜電對稱量結果的影響
