论文摘要
广泛或类似物质的数量的起源的历史过程分为两个步骤。首先,发现了全球保护或不保存。直到后来才有可能以连续性方程式的形式在本地制定平衡。在能量,动量和熵中可以清楚地看到此过程。经过漫长而复杂的历史,在19世纪之交左右的短时间内,已经在三个数量的时间内实现了局部平衡的定量描述。新想法可以大大简化能量,动力和熵的教学。但是,在所有三种情况下,今天的物理语言基本上与尚无本地平衡的时候相同。
The historical process of the genesis of the extensive or substance-like quantities took place in two steps. First, global conservation or non-conservation was discovered. Only later did it become possible to formulate the balance locally in the form of a continuity equation. This process can be clearly seen in energy, momentum, and entropy. After a long and intricate history, the quantitative description of the local balance has been achieved for all of the three quantities in a surprisingly short period of time around the turn of the 19th to the 20th century. The new ideas could have simplified considerably the teaching of energy, momentum, and entropy. However, in all three cases, today's language of physics remained essentially the same as it was at the time when a local balancing was not yet possible.
