摘要
用家蚕微粒子(Nosemabombycis)对家蚕进行攻毒,诱发微粒子病发生,对染病蚕肠液、血液、体内微粒子种群数量动态分别进行了研究,结果表明:肠液内微粒子种群变化呈锯齿形上升变化,其增长规律可用一元线性回归方程表示;血液中微粒子种群随时间函数动态变化的数学模式可用3次方程来拟合;蚕体内微粒子种群则按指数增长方式随时间函数动态变化,属J型数学增长模式.从3个系统层次,3种不同的增长规律,揭示了3种完全不同的增殖机制.
Pebrine disease can be triggered by feeding silkworm on Nosema bombycis (N.b). Study on the population of infected silkworms proves that:the increasing population curve of N.b in intestines liquid is hackly, the dynamic can be described with the linear regression equation. The variation of N.b population in blood can be described with the cubic equation. And the mathematical model of N.b population in the body to the time is exponential function, which belongs to the J increasing curve. In this paper, three different ways of increasing are revealed by three different levels and three different increasing rules.
