Chinese college students send self-developed satellite into orbit_我的网站

一 |     (ECNS) -- A student satellite team from Harbin Institute of Technology successfully launched its self-developed Lilac-3 satellite into orbit, marking a milestone for a young team involved in independent satellite development.    The satellite was launched aboard a Gravity-1 Y4 carrier rocket from waters near Shanghai at 10:54 a.m. on July 22. Telemetry data was successfully received at 11:41 a.m., confirming the mission’s success.    Lilac-3 features an ultra-flat disk-shaped design, with its main body measuring less than 5 centimeters in thickness. The design allows satellites to be stacked more efficiently during launches and is expected to support future low-orbit constellation deployment.    When the project began, about 70% of team members were undergraduates, with an average age of 22. Most had no previous experience with complete satellite engineering projects and learned new technologies during the development process.    After the first Lilac-3 failed to enter orbit due to a launch failure earlier this year, the team rebuilt the satellite within three months, improving its performance and adding new experimental tasks.    Founded in 2012, this team is the first university student team in China to independently complete satellite design, development and mission management. Lilac-3 is the fourth satellite successfully launched by the team.    (By Intern Liu Shuangjing, Zhang Dongfang)                    。    也就是说，在苹果的产品规划中，这两者并不是继承关系，而是错位细分新的市场，那它俩到底有啥区别呢？首先最大的改变就是外观了，iPad 10采用了10.9英寸的四边等宽全面屏，正面Home键被砍，改成顶部与电源键二合一的指纹识别，机身也换上了直角边框。而iPad 9则是延用了5年的外观，屏幕尺寸为10.2英寸。但需要注意的是，iPad 10并没有升级屏幕素质，依然是264ppi的分辨率，以及最大500尼特亮度，支持原彩显示，与前代完全一致。性能方面，iPad 10升级到了A14芯片，与iPhone 12同款，不过入门版多数用来上网课看视频，对比前代A13芯片，日常使用其实没有太大区别，新款的蜂窝版加入了5G网络。拍照方面也有升级，iPad 10从前代的800万像素升级到了1200万像素，新增了4K视频和1080P/60FPS视频拍摄，以及最高1080P/240FPS的慢动作视频拍摄。前置均为1200万像素，不过新款前摄被放到了长边上，更适合网课、视频会议的场景。接口方面也是一个重要的改变，新款终于同上了USB-C接口，但也带来了一个非常奇葩的问题，因为依然仅支持Apple Pencil 第一代，需要用Lightning给笔充电，所以还需要购买转接头。其他规格上，iPad 10与iPad 9则是完全保持一致了。
