The 220GHz double-corrugated rectangular waveguide backward wave oscillator(BWO)was investigated in this paper.Two parallel corrugations that are enclosed in a rectangular waveguide form a beam channel that supports an interaction with a cylindrical electron beam.Field distributing,dispersion curve and coupling impedance were analyzed using electromagnetic software CST MWS,and the 3D beam-wave interaction was simulated using CST PS.Simulation results show that the double-corrugated rectangular waveguide BWO can obtain 761mW output power at 220GHz and 1319mW output power at 234GHz.The high-power potential of the double-corrugated rectangular waveguide for terahertz(THz)vacuum devices has been demonstrated.

二氢月桂烯醇(DHMOH)是一种非常重要的香料,其合成方法主要有间接水合法(两步法)和直接水合法(一步法)。目前工业上所用两步法生产周期长,并对环境具有很大的危害。近年来研究热点是固体酸催化二氢月桂烯(DHM)一步水合制备DHMOH,但存在DHM转化率不高以及反应时间长等问题,不利于工业应用。本文采用自制的全回流塔式反应器,以异丙醇作溶剂,对大孔强酸性阳离子交换树脂催化DHM直接水合制备DHMOH
