一、學生鬧鐘買什么樣的好
對于學生(sheng)來說(shuo),鬧(nao)(nao)(nao)(nao)(nao)鐘(zhong)是必不(bu)可少的(de)一件物品,畢(bi)竟(jing)每天起這么早,如果沒有個(ge)(ge)鬧(nao)(nao)(nao)(nao)(nao)鐘(zhong)的(de)話還是很(hen)容易(yi)遲到的(de),鬧(nao)(nao)(nao)(nao)(nao)鐘(zhong)的(de)種(zhong)類有很(hen)多,常(chang)見的(de)有機械鬧(nao)(nao)(nao)(nao)(nao)鐘(zhong)、石英鬧(nao)(nao)(nao)(nao)(nao)鐘(zhong)、電(dian)子鬧(nao)(nao)(nao)(nao)(nao)鐘(zhong)等,不(bu)過學生(sheng)鬧(nao)(nao)(nao)(nao)(nao)鐘(zhong)選購要注意(yi)幾個(ge)(ge)方面:
1、建議不(bu)要選機械鬧(nao)鐘(zhong),因為機械鬧(nao)鐘(zhong)采用發(fa)條作為動力(li)源(yuan),需要每天擰(ning)發(fa)條,麻煩就(jiu)不(bu)說了,時針(zhen)、分(fen)針(zhen)和秒針(zhen)轉動還有一(yi)定的(de)聲音,如果晚上(shang)失眠(mian)或者(zhe)睡眠(mian)淺的(de)情況下,很容易(yi)被鬧(nao)鐘(zhong)走字的(de)聲音吵醒,影(ying)響睡眠(mian)質(zhi)量。
2、學生(sheng)鬧(nao)鐘要選擇方(fang)便易用的,例(li)如電子(zi)鬧(nao)鐘,設置(zhi)鬧(nao)鈴時間比較方(fang)便,早上被鬧(nao)鐘鬧(nao)醒,按下去就好了,不會用起來很麻煩。
3、如(ru)果(guo)經濟條件(jian)允許(xu),預算(suan)比較(jiao)充足的話,還(huan)可以考慮給孩子購買一(yi)個智能鬧鐘,不僅方便易(yi)用安靜,而且(qie)智能化(hua)程度高,能智能喚醒,保護學生的睡眠(mian)質(zhi)量(liang)。
二、學生鬧鐘充電的好還是電池的好
因為機(ji)械鬧(nao)(nao)鐘(zhong)走字的聲(sheng)音可能(neng)會影響到(dao)睡眠(mian),所以適合學(xue)生使用(yong)的鬧(nao)(nao)鐘(zhong)一(yi)(yi)般(ban)是電(dian)(dian)子(zi)鬧(nao)(nao)鐘(zhong)或智能(neng)鬧(nao)(nao)鐘(zhong),不過市面上的電(dian)(dian)子(zi)鬧(nao)(nao)鐘(zhong)一(yi)(yi)般(ban)有充電(dian)(dian)鬧(nao)(nao)鐘(zhong)和電(dian)(dian)池鬧(nao)(nao)鐘(zhong)兩(liang)種,那么充電(dian)(dian)鬧(nao)(nao)鐘(zhong)和電(dian)(dian)池鬧(nao)(nao)鐘(zhong)哪種好呢?
充電(dian)(dian)(dian)(dian)鬧(nao)鐘一般(ban)使(shi)用的是鉛酸電(dian)(dian)(dian)(dian)池(chi)(chi)、鎳鎘(ge)電(dian)(dian)(dian)(dian)池(chi)(chi)、鎳鐵(tie)電(dian)(dian)(dian)(dian)池(chi)(chi)、鎳氫電(dian)(dian)(dian)(dian)池(chi)(chi)、鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi)等作為電(dian)(dian)(dian)(dian)源(yuan),循環壽命長,一般(ban)可(ke)全充放電(dian)(dian)(dian)(dian)200多次,使(shi)用起來比較環保。電(dian)(dian)(dian)(dian)池(chi)(chi)鬧(nao)鐘使(shi)用的是一次性電(dian)(dian)(dian)(dian)池(chi)(chi),一般(ban)采用1.5V左(zuo)右的電(dian)(dian)(dian)(dian)池(chi)(chi)即可(ke)支撐(cheng)一年(nian)左(zuo)右,使(shi)用完畢后丟棄掉,重新安裝一個電(dian)(dian)(dian)(dian)池(chi)(chi)又可(ke)以(yi)繼(ji)續使(shi)用,比較方便。
綜上所述,充電鬧鐘和電池鬧鐘各有各的優缺點,一般情況下,學生鬧鐘要求方便實用,充電鬧鐘用(yong)起來還(huan)是(shi)比電(dian)池(chi)鬧(nao)鐘要(yao)麻煩一些的,因此(ci)學生還(huan)是(shi)更適合使用(yong)電(dian)池(chi)鬧(nao)鐘。
