足够的压力是玉米籽粒膨爆的必要条件和直接原因。爆裂玉米籽粒果皮及胚乳结构紧密,在其含水率为13％—15％的情况下,在高温(177℃)条件下,其内部水分汽化,形成足够压力,故而能自行爆破。而马齿型玉米籽粒在高温条件下不能形成这种压力条件,须靠外部创造高压条件才能膨爆。 Adequate pressure is the necessary conditions and the direct cause of corn kernel explosion. The peel and endosperm of popcorn kernels are compact in structure. Under the condition of water content of 13% -15%, the internal moisture of the popcorn kernel is vaporized at a high temperature (177 ° C) to form sufficient pressure so that it can self-explode. The dent corn seeds in the high temperature conditions can not form such pressure conditions, to rely on external conditions to create high-pressure burst explosion.
