中文版：
地球经纬仪教学模型（32cm J34009）是一款专为初高中地理教学设计的立体化教具，通过直观的三维模型帮助学生掌握地球运动、经纬度划分等核心地理知识。产品以1:40,000,000比例还原地球形态，直径32厘米的球体表面采用高清覆膜印刷技术，精准标注经线、纬线、赤道、南北回归线及极圈等重要地理标识，同时呈现七大洲四大洋的轮廓分布与主要国家地理位置。
本产品采用抗冲击ABS环保材质制成，球体通过15°倾斜角设计还原地球实际公转姿态，内置钢制旋转轴支持双向360°顺滑转动，便于演示地球自转与昼夜更替现象。球面特别以不同色阶标注温度带分布，并搭配可调节式金属支架，支持多角度观测与小组协作学习。配套使用指南提供10种课堂教学方案，涵盖时区换算、季节成因、极昼极夜等知识点解析。
在教学实践中，教师可通过经纬网格定位演示，引导学生理解坐标系统的空间应用；结合晨昏线动态模拟，帮助学生构建地球公转与太阳直射点移动的立体认知。产品边缘经线刻度精确至1°，纬线间隔清晰标注，支持实地测量与地图绘制的拓展教学。

The Terrestrial Globe with Latitude & Longitude (Model J34009, 32cm) is an innovative educational tool designed for middle and high school geography curricula. This three-dimensional teaching aid features a 32cm diameter sphere constructed from eco-friendly ABS material, accurately scaled at 1:40,000,000 to demonstrate Earth s geographical characteristics. The anti-glare surface employs advanced printing technology to display clearly defined parallels, meridians, equator, tropics, and polar circles, along with continental outlines and oceanic divisions.
The globe s 23.5° axial tilt replicates Earth s orbital inclination, supported by a durable steel rotation mechanism that enables smooth 360° movement for simulating planetary rotation and day-night cycles. Color-coded thermal zones and adjustable stainless steel stand enhance visual learning, while the reinforced base ensures stability during classroom demonstrations. The accompanying teaching manual contains 10 structured lesson plans covering time zone calculations, seasonal variations, and polar phenomena.
Key educational applications include:
- Interactive exploration of coordinate positioning systems
- Visualizing the relationship between Earth s tilt and solar radiation patterns
- Comparative analysis of map projections through hands-on measurement
- Demonstrating longitudinal time differences using rotary motion
Precision-etched degree markings (1° interval for longitude) facilitate practical exercises in navigation and cartography. The scratch-resistant surface maintains legibility for long-term classroom use, making it an essential resource for building spatial reasoning skills and fostering global awareness in geography education.
