A THz log-periodic toothed trapezoidal antenna with a high directivity and a wide operational bandwidth is reported.The log-periodic structure is used in the design to achieve wide bandwidth.A hemispherical dielectric lens is added to improve the directivity and the efficiency of the antenna.The simulated performance of the antenna shows that the use of Luneburg lens with appropriate materials and thickness can improve the directivity by about 8 dB and the side lobe by 10dB.

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
