螺旋测微器-千分尺(Spiral micrometer)

“羡鱼情”出自唐代孟浩然的《望洞庭湖赠张丞相》，“欲济无舟楫，端居耻圣明。 坐观垂钓者，徒有羡鱼情”。 本意是作者想要出仕，却苦无门路。我们这里指：老师想要使用科技产品却苦无门路；学生想要学以致用，却苦无门路；科技工作者想要赋能教育，却苦无门路。 我们致力于做教育产品（包括但不仅限于理化生实验），科技赋能教育，探索科技与教育的融合，做内容的生产者。 帮助老师学习和使用科技产品和工具，提高工作效率。 帮助学生使用科技产品和工具进行学习，再用学到的科学知识创造工具。 探索STEAM教育。让学生真正参与到产品的研发中来，学以致用，不再只是纸上谈兵，提高运用知识的能力，提高学习的兴趣。 官网http://xianyuqing.com/ "xianyuqing" comes from Meng Haoran's "looking at the Dongting Lake to Prime Minister Zhang" in the Tang Dynasty. "If you want to help others without boats, you should be ashamed of being saintly and wise. If you sit and watch anglers, you will only have admiration for fish". The original intention is that the author wants to become an official, but he has no way out. We mean here: teachers want to use scientific and technological products but have no way; Students want to apply what they have learned, but they have no way out; Science and technology workers want to empower education, but they have no way. We are committed to making educational products (including but not limited to physical, chemical and biological experiments), science and technology empowering education, exploring the integration of science and technology and education, and becoming content producers. Help teachers learn and use scientific and technological products and tools to improve work efficiency. Help students use scientific and technological products and tools for learning, and then use the scientific knowledge they have learned to create tools. Explore steam education. Let students really participate in the research and development of products, apply what they have learned, no longer just talk on paper, improve their ability to use knowledge, and improve their interest in learning.
