油茶作为中国的特产,其深加工具有重要的现实意义。测定了油茶蒲水份含量75%左右,油茶籽的水份含量56%左右,油茶果的比热容为2.1～2.5J/g℃。探讨了在微波作用下,油茶蒲裂纹的主要形式有十字型、近1200分开型等,并计算了其临界断裂强度因子与刚度的关系。理论和实践证明,自然形状导致油茶蒲裂纹的位置是在油茶籽最凸起处,因为纤维组织最薄弱,微波作用下油茶果的最初裂开点是其自然采摘最下端。

As one of the Chinese special product,deep processing of Camellia oleifera has important practical significance.The water content of Camellia oleifera out-shell was about 75%,the seed＇s was about 56%,the specific heat capacity was about 2.1~2.5 J/g℃.Under the microwave effect,some crack forms of Camellia oleifera have been studied,such as types of cruciform cracks,near 1200 cracks,etc.The relation of critical fracture strength factor to rigidity has been calculated=（6.2~9.8）＊103E.Practice and theory show that natural shape results the crac...
