An experimental technique is demonstrated for acoustically levitating aqueous foam drops and exciting their spheroidal modes. This allows fundamental studies of foam-drop dynamics that provide an alternative means of estimating the viscoelastic properties of the foam. One unique advantage of the technique is the lack of interactions between the foam and container surfaces, which must be accounted for in other techniques. Results are presented......

奶粉中一定的水分含量可保持食品品質(zhì)，大大延長食品的保質(zhì)期。原料（如全脂牛奶、脫脂牛奶）的變化以及加工工藝的變化導致了奶粉成品種類繁多。奶粉成品包括嬰兒配方奶粉、脫脂奶粉、酪蛋白 粉、乳清蛋白 粉和乳糖粉。本文介紹并討論了測定 Warren Spring 內(nèi)聚強度和奶粉粉壁摩擦角的方法。測量采用 Anton Paar 模塊化緊湊型流變儀進行。[詳細]
