普通高中课程标准试验教科书必修《地理》(第一册·鲁教版),经全国中小学教材审定委员会2004年初审通过,作为使用和研读该版本教材的老师,在学习过程中发现一些值得商榷的问题,现举例如下:1.天体系统的形成教材P_3“距离相近的天体因相互吸引而相互绕转,构成不同级别的天体系统。”天体系统是一种天体绕另一种天体运转而非相互绕转。例如,地月系中地球是该系统的中心天体,因为地球质量是月球的81.1倍,其共同质量中心落在离地心4278千米,即位于地面以下约1650千米的地方。地球、月球都围绕这一共同质心公转,但一般把地月系的运动说成是月球对于地球的绕转,并不存在地球绕月球的运转。建议改为“距离相近的天体因相互吸引而导致一种天体绕另一中心天体运转,构成不同级别的天体系统。”2.极点是否有自转速度教材P_(11)“赤道上线速度最大,两极点为零。”做圆周运动的物体或质点既有角速度又有线速 Ordinary high school curriculum standard test textbook compulsory “geography” (first volume · Lu education version), by the national primary and secondary textbook approval committee passed the first instance in 2004, as the use and study of the version of the textbook teacher, found in the learning process is worth discussing The following examples are given: 1. The formation of the celestial system Textbook P_3 “celestial bodies with similar distances due to mutual attraction revolve around each other to form different levels of celestial bodies.” The celestial body system is a kind of celestial body that runs around another celestial body Instead of mutual rotation. For example, Earth is the central celestial body of the system in the Earth-Moon system because the earth’s mass is 81.1 times that of the moon and its common mass center falls 4278 km from the earth’s center, ie, about 1650 km below the ground. Earth and the moon revolve around this common center of mass. However, the movement of the Earth-Moon system is generally described as the lunar rotation of the Earth and there is no movement of the Earth around the moon. Proposal to read “celestial bodies with similar distances and mutual attraction, causing a celestial body to work around another celestial body and form different levels of celestial bodies.” 2. Whether the poles have a rotation speed P_ (11) “Equatorial on-line speed Maximum, zero on both poles. ”Objects or particles that do circular motion have both angular velocity and linear velocity
