    • 在化工業界大約有一半以上的工業成品以及四分之三的工業原料是以顆粒體形狀存在，一定需要顆粒體的儲存裝置；顆粒體材料一般均存放在儲槽中。儲槽貯存器在工業界中是一個很普遍的應用，但傳統業界在使用上多採用經驗或半經驗的方式做為設計的方法，要考慮到許多不同的因素及條件。
    在本研究中主要是要探討儲槽中的水份含量對顆粒體的流動的影響，藉著改變儲槽中的水份含量以及儲槽的外型，來觀測儲槽中因不同水份含量對顆粒體流動產生的影響。並藉由停滯區域之觀測，與顆粒體之性質進行比較之間的關聯性。

    The yield locus of a wet material was shifted to the left of that of a dry specimen by a constant value equal to the compressive isostatic stress due to pendular bridge. For material with straight yield loci, the shift was computed from the unaxial tensile strength, either measured in a tensile strength tester, and the angle of internal friction of the material.
