  1. When the chemical ( usually diluted with oil - based carrier ) is heated, it is vaporized in a combustion chamber and then expelled via an outlet tube to form a dense fog cloud when it condenses on contact with cool ambient air

    當化學液體（通常以油劑稀釋）加熱后，經排氣管排出，一旦接觸外界溫度較低的空氣便凝結成一團煙霧。即使地方給茂密的植物或其他
  2. This paper analyzed the criterion of the safety evacuation, factors affected on safety evacuation, calculating method of evacuation time and the smoke layer falling time, typically introduced the several calculation method that i had know, such as the japan three steps calculation method based on experience ( awareness time, travel time, queue time ), two computer modeling calculation method such as simulex and exodus and a spatial grid computer model of hongkong. and it also analyzed and certificated the application scope and difference between the computer modeling calculation methods and japan method with the practical project. all these are aimed to provided preference for performance - based design method and design of computer program for modeling evacuation of people, and advanced the steps of performance - based fire protection design method in our country

    本文對安全疏散的標準、影響安全疏散的因素、疏散時間和影響疏散的煙層下降時間的計算等方面進行分析，重點介紹了作者所掌握的疏散時間的幾種計算方法，日本的三步驟疏散時間經驗公式計算方法（察覺時間、步行時間、排隊等待時間） 、以及兩種計算機疏散計算模型simulex和exodus 、香港的空間網格計算機模型的計算方法等，並結合實際工程來分析驗證疏散計算機軟體模擬和日本經驗公式法之間的不同與適用性，並對疏散計算中的重要參數，人員密度和疏散人數的確定進行介紹，旨在為我國的性能化疏散設計與疏散模擬的計算機軟體的編制提供參考，同時促進我國性能化防火設計的進程。
  3. After analyze the foundation of the current national code ( code for fire protection design of tall buildings gb500045 - 95 ) through experiments and fire simulations, the author has found that there are some limitations on the use of this national code for the designing of smoke management system in an atrium. this paper has been discovered that it is not enough when using the smoke layer interface height as a criterion to make an assessment on the safety rate in a building fire, or to calculate the egress time

    通過上述實驗研究和數值模擬研究，發現當採用我國現行的《高層民用建築防火設計規范》 （ gb50045 - 95 ）來指導中庭建築的排煙系統設計時，在本文設計的火災場景條件下（參照實際的中庭商場調研情況，即火災載荷密度較大時） ，對于本文實驗研究中所採用的相似模型及原型建築，無論是採用自然排煙或者是採用機械排煙，其排煙量皆不足。
