A brief analysis of essential pragmatic factor groups in verbal communication 淺析語(yǔ)言交際中的語(yǔ)用要素群
In the research , a set of simulation equipment is developed to examine the drivers " static and dynamic fatigue . recur to the apparatus , contrast and control experiment are made among different ages , workload intension and workload factors group . the endings summarize as following : ( 1 ) driving sensation fatigue investigation ( investigation of psychological and physiologic index and contrast investigation of fatigue ) ; continuous driving load and discrete driving load investigation of fatigue ? ?門)駕駛疲勞平衡穩(wěn)定性是通過(guò)在力檢測(cè)臺(tái)上描繪人體重心軌跡的方法,提出檢測(cè)駕駛員疲勞平衡穩(wěn)定指數(shù),在不同狀態(tài)下(傾斜度15 30 ‘以及閉目等狀態(tài)下)對(duì)不同負(fù)荷、不同年齡分別進(jìn)行測(cè)試,建立駕駛疲勞客觀測(cè)試評(píng)價(jià)體系; n )經(jīng)實(shí)驗(yàn)室研究與現(xiàn)場(chǎng)調(diào)查,通過(guò)對(duì)駕駛疲勞與駕駛時(shí)間、駕駛速度等關(guān)系的研究,提出了不同年齡、不同條件下的最大連續(xù)安全駕駛時(shí)間標(biāo)準(zhǔn),日駕駛時(shí)間標(biāo)準(zhǔn),最大安全行車速度標(biāo)準(zhǔn)等。
