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)                    。    夏日炎炎，涉水徒步、溪流穿越等户外活动热度高涨，EVA溯溪鞋凭借独特优势，成为众多年轻消费者追捧的户外装备。为回应消费热点、引导理性选购，杭州市消费者权益保护委员会（以下简称“杭州市消保委”）联合必维申美商品检测（上海）有限公司，开展了EVA溯溪鞋比较试验。本次比较试验采用“问卷调查、客观测试、消费者体验”三位一体联动模式，以普通消费者的身份，从线下实体店及各大电商平台共购买了27款样品，包括运动品牌、快时尚品牌、户外品牌及电商平台中销量较高的品牌等，样品单价从9元到303.99元不等。

二 | 购买渠道包括杭州实体商场和主流，其中电商平台覆盖天猫、京东、唯品会、得物、抖音等平台。本次比较试验27款样品的特性项目指标总体呈现中等水平，在轻便性、耐摩擦色牢度、鞋底硬度等方面表现良好，但部分样品在防滑、耐磨、压缩变形等耐用性指标上仍有提升空间，部分样品的标识存在信息缺失或不规范的情况，有待进一步规范。防滑性能测试结果显示，前掌防滑性能略优于后跟，但差距不大；干态优于湿态，湿态防滑性能相比干态平均下降22.6%；大部分样品干态防滑性能良好，能满足日常干燥路面使用；湿态防滑平均值为0.494，能满足日常溯溪场景需求。耐磨性能直接影响溯溪鞋的使用寿命。数值越低耐磨性能越强。测试结果显示，27款样品不同品牌之间差异较为明显。结果显示，27款样品均在三星及以上，其中16款样品达到四星及以上，标称品牌分别为：MERRELL迈乐、SENMA森马、安踏、乔丹、CROCS、XTEP特步、回力、朴西、红豆、TZLDN/利达妮、SKECHERS斯凯奇、海澜之家HLA、DECATHLON、匹克、HUMTTO悍途、MINISO。链接：杭州市消保委发布消费提醒按需选型，聚焦实用性能选购EVA溯溪鞋时，应结合日常休闲玩水、专业溯溪、短途徒步等实际场景，明确自身需求。重点检查鞋头防撞、脚踝支撑、防滑大底、排水结构等核心配置，确保鞋子具备实用性能。同时，根据自身脚型挑选合脚款式，避免磨脚、易进砂石等常见问题，切勿盲目跟风网红款式，确保选购的溯溪鞋既实用又舒适。理性甄别宣传，规避营销陷阱面对商家宣传，需保持理性，客观看待产品内容。

三 | 仔细查看鞋材用料、性能参数等相关说明，警惕夸大防滑、耐磨、速干等功能的不实宣传。必要时，可参考实际评测、官方选购指南等权威信息，辅助决策，避免陷入营销陷阱，切实维护自身消费权益。
