4、的圆筒组成。水从上面的圆筒穿过一个小孔滴入下面的圆筒。水滴完了，就是某个时辰过去了。大一点儿的漏壶灌一次水可报六个小时，然后再重新装满水。*漏壶钟：* 漏水浑天仪：东汉张衡制造漏水转浑天仪，用齿轮系统把浑象和计时漏壶联结起来，漏壶滴水推动浑象均匀地旋转，一天刚好转一周，这是最早出现的机械钟。* 机械打点塔钟:1350年，意大利的丹蒂制造出第一台结构简单的机械打点塔钟，日差为1530分钟,指示机构只有时针*游丝:1660年英国的胡克发明游丝，并用后退式擒纵机构代替了冕状轮擒纵机构；游丝的发明大大推动了钟表的发展。*1582年前后，意大利的伽利略发明了重力摆。* 1675年，英国的克莱门特用叉瓦装

5、置制成最简单的锚式擒纵机构，这种机构一直沿用在简便摆锤式挂钟中。* 1695年，英国的汤姆平发明工字轮擒纵机构；1715年，英国的格雷厄姆又发明了静止式擒纵机构，弥补了后退式擒纵机构的不足，为发展精密机械钟表打下了基础；1765年，英国的马奇发明自由锚式擒纵机构，即现代叉瓦式擒纵机构的前身；17281759年，英国的哈里森制造出高精度的标准航海钟；17751780年，英国的阿诺德创造出精密表用擒纵机构* 1819世纪，钟表制造业已逐步实现工业化生产，并达到相当高的水平。20世纪，随着电子工业的迅速发展，电池驱动钟、交流电钟、电机械表、指针式石英电子钟表、数字式石英电子钟表相继问世，钟表的日差已
