当涌水量小于10L/s时,用三角堰;大于10/s时,采用梯形堰或矩形堰测量(见图3-1)。测得堰口高度(h)及堰口宽度b(单位为cm),分别用下列公式计算: (1)三角堰:

1.在盛水的鼓泡吸收器中通入纯CO2气,经长期接触后测得水中CO2的平衡溶解度为 2.857×102mol/L溶液。 鼓泡器中的总压为101.3kPa,水温30℃,溶液的密度pm=996kg/m3求亨利系数,并将此实验值与文献值E=188.5MPa 作比较

3.5.拉格朗日方程的研究 1.守恒律和时空对称性之间的关系(参阅教材57-59页) 物理规律和时空结构之间存在密切的联系。下面我们来分析守恒律和时空对称性之间的关系。我们在这 里考虑的时空对称性是指时间、空间的均匀性和空间的各向同性,也就是在经历时间、空间平移或空间 转动后物理规律保持不变的性质。而力学规律的不变性体现在L的不变性
