Stifel维持Landstar股票"持有"评级，关注数据中心货运前景

2026年5月，中国科学院大连化学物理研究所研制的智能透射电镜系统原眼一号通过科技成果鉴定。团队联合沈阳自动化研究所，把样品传递、电子光学调整、微小目标定位、图像采集与实时分析连接起来，让传统依赖操作人员反复调节的显微观察形成自动化流程。

在连续72小时运行考核中，系统以分子筛等催化剂样品为对象，日均分析168个样品、采集超过4000张图像，并自动整理颗粒尺寸、分散情况和晶体结构等统计信息。研究重点是让电镜不只自动拍照，还能感知设备状态、协调不同操作并生成分析结果。大量一致采集的数据有望支持催化材料筛选和结构规律研究，也为实验设备与人工智能结合提供案例。公告中的处理量和效率提升对应特定样品与测试任务，不能直接推广到所有材料。对不同样品的制备、成像条件及结果解释，仍需要建立适配流程和必要的专业核查。
