中文版：
地球經(jīng)緯儀教學(xué)模型（32cm J34009）是一款專為初高中地理教學(xué)設(shè)計的立體化教具，通過直觀的三維模型幫助學(xué)生掌握地球運動、經(jīng)緯度劃分等核心地理知識。產(chǎn)品以1:40,000,000比例還原地球形態(tài)，直徑32厘米的球體表面采用高清覆膜印刷技術(shù)，精準(zhǔn)標(biāo)注經(jīng)線、緯線、赤道、南北回歸線及極圈等重要地理標(biāo)識，同時呈現(xiàn)七大洲四大洋的輪廓分布與主要國家地理位置。
本產(chǎn)品采用抗沖擊ABS環(huán)保材質(zhì)制成，球體通過15°傾斜角設(shè)計還原地球?qū)嶋H公轉(zhuǎn)姿態(tài)，內(nèi)置鋼制旋轉(zhuǎn)軸支持雙向360°順滑轉(zhuǎn)動，便于演示地球自轉(zhuǎn)與晝夜更替現(xiàn)象。球面特別以不同色階標(biāo)注溫度帶分布，并搭配可調(diào)節(jié)式金屬支架，支持多角度觀測與小組協(xié)作學(xué)習(xí)。配套使用指南提供10種課堂教學(xué)方案，涵蓋時區(qū)換算、季節(jié)成因、極晝極夜等知識點解析。
在教學(xué)實踐中，教師可通過經(jīng)緯網(wǎng)格定位演示，引導(dǎo)學(xué)生理解坐標(biāo)系統(tǒng)的空間應(yīng)用；結(jié)合晨昏線動態(tài)模擬，幫助學(xué)生構(gòu)建地球公轉(zhuǎn)與太陽直射點移動的立體認(rèn)知。產(chǎn)品邊緣經(jīng)線刻度精確至1°，緯線間隔清晰標(biāo)注，支持實地測量與地圖繪制的拓展教學(xué)。
English Version:
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.
