现在吾们再把有关配方的几个较具体的问题提出,加以简略的讨论。吾们知道化学工业制造法一类书中的配方,各种成分的分量是不一律的。所用的单位,有的是米制的克,或仟克,有的是英制的磅或两;有的不用重量而用容积,有的用百分数,有的索性一概不附单位名称,几乎从头到底,总是不会一致的。这是因为各国的衡量制度颇有不同,而且开示这种配方的人,都从自己习用的单位写出,所以有这样的差异。但是这对于吾们试验的人,是没有什么关系的。譬如配
Now let’s put forward a few more specific questions about the formula and give a brief discussion. We know that the chemical industry manufacturing law a book in the formula, the composition of the various components are not uniform. Some units used, some grams of rice, or grams, some British pounds or two; some without the use of volume and volume, and some with the percentage, and some are simply not attached to the name of the unit, almost from start to finish, will not always Consistent. This is because the measurement system in each country is quite different, and the people who reveal the formula are all written from the units they used to use. Therefore, there are such differences. But this does not matter to the people we test. For example with
