In mobile bed experiments, the measurement of sediment concentration needs to be real-time and accurate. 摘要動(dòng)床河工模型試驗中，需要對泥沙濃度進(jìn)行實(shí)時(shí)和精確的測量。
But it has some limitations of geometry structure, so scaling up the draft tube spouted bed is an urgent task. 但是導向管?chē)妱?dòng)床的幾何結構也有一定的限制。
