| 中文摘要: |
| 以激光作为强辐射源对煤油、轻柴油和重柴油进行了直接引燃试验，研究了引燃时间受入射辐射热强度、油品性质和热辐射入射角度影响的关系。煤油、轻柴油和重柴油能被高于２．３ｋＷ／ｃｍ２辐射强度的激光束瞬间引燃；采用线性外推方法确定引燃这些油品所需激光束的最小辐射强度分别为０．６７、０．４６和０．３２ｋＷ／ｃｍ２；提出引燃时间可用ｔ＝ｋＩａ（Ｔ／１００）ｂ经验式表示。 |
| 英文摘要: |
| The tests for ignition of kerosene, light and heavy diesals have been carrid out with laser as a radiative source of high intensity. The effects on ignition of the incident radiant flux, incident angle of the laser beam and the property of the fuels aer studied. The three fuels can be instantly ignited by laser with the fluxes of more than 2.3kw/cm 2. The minimum incident fluxes for ignition are also determined by means of linear extrapolation and the values for derosene, light and heavy diesals are respectively 0.67, 0.46 and 0.32kw/cm 2. The experimental formula of ignition time is presented with the form of t=kI a(T/100) b. |
