本文试图用三个推算公式,即①b=a(1-C%)~n;②∫(1+b)~(x-1)+(1+B)~x/2 dxfromx_1tox_2:③∫(1-c%)~x(1+B)~(x-1)+(1+B)~x/2 dxfromx_1tox_2,展望2000年我国结核病流行病学某些指标的变化,并探讨有关防治措施的作用。从数学公式本身看是可以反映事物变化的规律,但应用于流行病学指标的推算,尚需由今后的实践验证数学公式推断的实用性与价值。
In this paper, we try to use three formulas: ①b = a (1-C%) ~ n; ②∫ (1 + b) ~ (x-1) + (1 + B) ~ x / 2 dxfromx_1tox_2: ③∫ -c%) ~ x (1 + B) ~ (x-1) + (1 + B) ~ x / 2 dxfromx_1tox_2, looking forward to the changes of some indicators of epidemiology of tuberculosis in China in 2000, and discussing the role of prevention and treatment measures . It can be seen from the mathematical formula itself that it can reflect the change of things. However, it is still necessary to prove the practicability and value of mathematical formula from the practical verification in the future when applied to the calculation of epidemiological indexes.
