Study on Adsorption of Vitamin M on Silver Colloid with SERS surface enhancement Raman spectroscopy

利用SERS表面增强拉曼光谱技术对 维生素 M在银胶颗粒表面吸附行为的研究

Taking Dong Jujube as experimental material the weight loss rate the decomposing rate the containment change of vitamin C of fruit are studied under high voltage static electric field ( HVEF ) with 20kV / m 60kV / m and 100kV / m.

以冬枣为材料，研究了 20kV/m，60kV/m和100kV/m高压静电场处理对果实质量损失率、腐烂率及果实 维生素C含量变化的影响。

The experimental results show that three-dimensional heat and mass transfer exist in the process of convective drying the surface temperature of Vitamin E soft capsule needs about 10 min to reach heat balance at 2 m / s air velocity and 27 ℃ .

实验结果表明，在使用热风对流干燥软胶囊的过程中，热质传递存在着三维的分布与变化，在风速为 2m/s、温度为27℃的热风中整个 维E软胶囊表面温度达到平衡约需10min。
