摘要： The present invention discloses a catalytic hydrogenation method for carbon nine resin, comprising the following steps: 1) adding a Pt—W—Y/γ-Al2O3 catalyst in the first half of a fixed bed, adding a Pd—Zr—Nd/γ-Al2O3 catalyst in the second half of the fixed bed, and feeding hydrogen for reduction; and 2) catalytic hydrogenating the pretreated carbon nine resin in the fixed bed. In the present invention, different catalysts capable of reacting under the same catalytic conditions are added in the first and second halves of the fixed bed, and the two different catalysts play different roles, and can be active and complementary to each other under the same conditions. The synergistic effect of the two catalysts plays a good catalytic role. Moreover, the production process is simplified, and the production cost is saved.

摘要： A manufacturing method of a channel type planar waveguide amplifier and a channel type planar waveguide amplifier. The method is to pattern the channel structures on the surface of the optical substrate, and then seal them together with rare earth doped chalcogenide glass into the quartz tube, and finally the channel-type waveguide structure is directly created via the melt-quenching method to achieve high quality planar waveguide amplifier. Excellent side wall roughness can be assured since the present invention does not have any direct etching of rare earth ions. Chemical composition and the activity of the rare earth ions can be maintained since the whole process is not involved in any decomposition of the glass into atoms, ions or clusters as that occurs during the fabrication process of the films deposited by the traditional methods like thermal evaporation and magnetron sputtering.

摘要： A low-sidelobe plate array antenna includes a radiation layer and a feed layer. The radiation layer is superimposed on the feed layer and includes a first plate and a radiation array disposed on the first plate. The radiation array is formed by n2 radiation units which are distributed in 2(k-1) rows and 2(k-1) columns. Each radiation unit in the radiation layer is constituted by two first radiation assemblies and two second radiation assemblies. Each first radiation assembly comprises a first rectangular bar, a first rectangular cavity, a second rectangular cavity and a third rectangular cavity. The first rectangular cavity, the second rectangular cavity and the third rectangular cavity in the first radiation assembly are stacked in presence of an azimuth deviation to form a three-layer coupled structure, and the first rectangular bar located in the first rectangular cavity can better restrain cross polarization and reduce the sidelobe.
