    摘要: A method for the preparation of compressed oxidant-fuel gas mixtures allowing to avoid (important) damages during filling, wherein one of the following two routes are followed:
    - a first route which can be called a "safe method" because the flammability range is not crossed during cylinder filling. This first "safe" route takes into account the cylinder test pressure to avoid any burst.
    - a second route which can be called an "accurate method" because minor components are first introduced in the cylinder, but in which during the addition of the last component, there is a risk of explosion, simple deflagration or detonation, since the flammability range is crossed. A safety margin is therefore added to take into account the error on flammability limit versus pressure curves.
    The diagrams of maximum pressure of filling to prevent accident are established in function of fuel concentration for lean mixtures and rich mixtures, as obtained from flammability limits and detonation limits versus pressure at ambient temperature. Maximum pressure is calculated from adiabatic flame temperature at constant volume and from parameters deduced from detonation theories available in the literature.
