Abstract: The present invention relates to the technical field of semiconductor materials, in particular to a method for preparing a composite substrate and a method for preparing a light-emitting element using same. A crisscross metal mask layer is formed on a substrate; in the subsequent nitride deposition process, because the nitride deposition temperature is higher than the vaporization temperature of the metal mask layer, a composite substrate having a specific hollow structure is formed; a light-emitting epitaxial layer is also formed on the composite substrate, wherein the hollow structure is a first pre-cutting passage, the gap between MESA patterns on the upper surface of the light-emitting epitaxial layer forms a second pre-cutting passage, so that when the laser performs cutting along the first pre-cutting passage and the second pre-cutting passage, damage to the edge area of a light-emitting element by the laser can be prevented due to the hollow structure of the first pre-cutting passage, thereby effectively solving the problem of the electricity leakage of the light-emitting element caused by damage to the epitaxial layer by excessively high laser energy.

Abstract: 一种阀及空调，涉及空调技术领域，该阀通过在第一连接部（1）的连接端的腔内固定阀座套管（2），并在阀座套管（2）内安装可伸缩的密封组件（3），同时在阀座套管（2）的腔内壁设置配合密封组件（3）形成密封的第一密封凸台（4），当与连接管接通通入制冷剂时，密封组件（3）会受力产生压缩，与第一密封凸台（4）分离导通，在未通入制冷剂之前，第一连接部（1）的连接端都是处于密封状态，从而具有自密封保压的功能，安装过程中只需直接与连接管连接即可，实现免抽真空，安装方便快捷，降低了工人安装的专业性和设备的专业性，减少安装时间，降低安装费用，同时连接操作过程中不会造成制冷剂泄露，避免造成环境污染，使空气无法进入空调系统，避免影响机器性能。
