內容簡介

　　作為作者過往多年間從事生物氣溶膠、顆粒與氣態(tài)污染物在多種室內高人口密度環(huán)境內傳播特性及暴露人員健康風險評估相關研究的結合與總結，本書通過獨特的視角，從流體力學角度出發(fā)，遵循氣溶膠類感染物的物理傳播特性，輔以計算模擬預測，分析還原了傳染性氣溶膠從感染者體內釋放，到最終被吸入后在他人呼吸道內傳輸沉積的完整過程。本書的另一特色在于通過將傳染性氣溶膠的生物特性參數與計算流體力學相結合，提供了一套可量化的健康感染風險評估體系。其成果在科技部國家重點基礎研究發(fā)展計劃（“973”計劃）、國家自然科學基金等多個項目的資助下完成。本書的研究內容屬交叉學科，可供建筑環(huán)境、生物工程、生物化學、流行病學、公共衛(wèi)生、病理學等專業(yè)的學生及研究人員參考。

作者簡介

　　顏屹寰，現于墨爾本皇家墨爾本理工大學（RMIT）任研究員，致力于研究污染物在室內及建筑環(huán)境內的傳播以及評估人體暴露在污染物下的感染風險，有著豐富的在大尺度機艙環(huán)境下的模擬經驗及技巧，并深入分析了機艙環(huán)境等高人口密度環(huán)境下污染物傳播的主要影響因素。深入參與了國家重點基礎研究發(fā)展計劃（973計劃），大型客機座艙內空氣環(huán)境控制的關系科學問題研究，曾獲得澳洲博士生獎學金（APA）全獎，以及國家優(yōu)秀自費留學生獎學金（全球僅500名）。
