在科研生产中有许多问题需要用到数学模型来解决。较为理想的数学模型往往是应用自然科学与工程科学基本原理,经过复杂的数学推导而建立。但是这些理想化的数学模型常常与实际情况相差很大,有时这种模型也很难建立。因此就要根据实际情况来建立数学模型,也就是我们通常所说的经验公式。这些经验公式看起来并不十分严格,但是很实用,在科研生产中有时针对某一个问题会有许多种这样的数学模型,我们将这类
There are many problems in scientific research and production that need to be solved by mathematical models. The ideal mathematical model is often applied to the basic principles of natural science and engineering science, through mathematical derivation and the establishment of complex. However, these idealized mathematical models are often very different from the actual situation, and sometimes this model is difficult to establish. Therefore, we must establish a mathematical model based on the actual situation, which is what we usually say empirical formula. These empirical formulas do not seem to be very strict, but they are very practical. There are many kinds of mathematical models that are sometimes used in scientific research and production for a certain problem.
