人教版高中地理必修1第三章第一节自然界的水循环教案
浅层地下水是贮存于地表松散堆积物中的潜水。主要受降水、气温、蒸发等气象因素影响，有明显的季节变化与日变化，并与河水有相应补给关系，即河水高于潜水面时，河水补给地下水，反之地下水补给河流；深层地下水是长时间内渗入地下深入储存起来的，它缓慢地流出补给河流，受气象因素影响很小，通常只有年变化，季节变化已不明显。当然，一条河流的河水补给来源往往不是单一的，而是以某一种形式为主的混合补给形式，对流域自然条件复杂的大的河流来说尤其如此。我国长江上游地区除雨水、地下水外，高原高山上冰川、积雪在夏季融化也补给河流；东北地区的河流，由春季融化积雪补给，夏季则由雨水和地下水补给；西北内陆盆地除雨水外，夏季高山冰川、积雪融化成为河流的主要补给形式。我国季风地区，大部分河流以雨水补给为主，而冬季则由地下水补给。

人教版新课标高中物理必修1弹力教案2篇
一般情况下，凡是支持物对物体的支持力，都是支持物因发生形变而对物体产生弹力。所以支持力的方向总是垂直于支持面而指向被支持的物体。例1：放在水平桌面上的书书由于重力的作用而压迫桌面，使书和桌面同时发生微小形变，要恢复原状，对桌面产生垂直于桌面向下的弹力f1，这就是书对桌面的压力；桌面由于发生微小的形变，对书产生垂直于书面向上的弹力f2，这就是桌面对书的支持力。学生分析：静止地放在倾斜木板上的书，书对木板的压力和木板对书的支持力。并画出力的示意图。结论：压力、支持力都是弹力。压力的方向总是垂直于支持面而指向被压的物体，支持力的方向总是垂直于支持面而指向被支持的物体。引导学生分析静止时，悬绳对重物的拉力及方向。引导得出：悬挂物由于重力的作用而拉紧悬绳，使重物、悬绳同时发生微小的形变。重物由于发生微小的形变，对悬绳产生竖直向下的弹力f1，这是物对绳的拉力；悬绳由于发生微小形变，对物产生竖直向上的弹力f2，这就是绳对物体的拉力。
