职业教育是培养高素质技术技能人才与促进经济社会高质量发展的基础性工程,在教育系统中具有独特价值。然而,当前职业教育社会认同度并不理想。在新《中华人民共和国职业教育法》出台后,“取消初中毕业后普职分流”的政策误读迅速引爆了各大媒体的热搜。本研究借助NVivo12.0对广大民众网络评论进行深入分析后发现,职业教育在入口公平、过程公平、结果公平上存在较大的社会争论。普职分流争议的根源在于职业教育存在社会偏见严重、体系不够完善、质量参差不齐、结果公平欠佳等问题。因此,提升职业教育社会认同度需要树立科学观念,完善职业教育体系,加强内涵建设,优化职教高考制度,改善评价环境。

面向国家战略和技术前沿开展有组织科研是高职院校实现高水平发展的新支点,也是职业教育高质量发展的时代诉求。但基于社会学新制度主义的视角,发现高职院校有组织科研建设面临政策制度偏差、配套条件不足、文化认知冲突等困境。因此,应建立多元错位的高职院校有组织科研制度体系,健全科学有效的高职院校有组织科研保障制度,凝聚合作共赢的高职院校有组织科研共同体意识,以期推动高职院校有组织科研建设。

离子迁移谱（Ion mobility spectrometry, IMS）检测速度快、灵敏度高、可便携，在化学毒剂、爆炸物、毒品和环境污染物等现场检测中发挥了重要作用。离子门作为IMS的关键部件，其向迁移区内注入离子团的离子数和时间宽度直接影响检测灵敏度和分辨能力。本研究采用Tyndall-Powell离子门（TPG）双平行栅结构可有效隔离电离区、离子门区和迁移区电场并独立调控的优势，发展了一种可以使迁移率歧视消除与离子团时域压缩同步增强的双效应TPG门控方法，提升了IMS的性能。搭建了TPG-IMS平台，考察了双效应TPG门控方法的离子门开门时间、离子门穿透电压和离子注入电压等参数对IMS信号强度和分辨能力的影响。结果表明，采用双效应TPG门控方法检测磷酸二乙酯（Diethyl phosphonate, DEP）和甲基磷酸二乙酯（Diethyl methylphosphonate, DEMP）混合样品，可以使迁移率（K0）较小的（DEP）2H+和（DEP·DEMP）H+的离子峰强度分别提升18和45倍，并保持分辨能力为～90，实现综合门控效能的提升；DEP的检出限从4 ppb (10–9)降至235 ppt (10–12), DEMP的检出限从5 ppb降至156 ppt。此门控方法仅调控TPG紧邻迁移区栅极的电势，无需改变迁移管结构，便于在现有商品化仪器上推广应用。

作者： yi-Gang xu the Guangzhou Institute of Geochemistry Chinese Academy of Sciences

Earth is the only known habitable planet in the solar system. Understanding how Earth developed its unique habitability has been the frontier of Earth sciences and has become one of the main themes of current deep-space explorations. What are the decisive factors that led to a habitable planet? What is the role of solid Earth processes in the origin of life and in modulating the surface environment? Are Earth’s habitability studies relevant to current challenges that human beings face? These questions have attracted the interest of both scientists and the public alike.
