运用现代控制理论中的系统方块图,对隔室模型进行处理,能很快写出药量—时间关系的拉普拉斯变换式。通过部分分式的逆拉普拉斯变换求出药量—时间关系式，大大易化了对隔室模型的理解,记忆和应用。药物动力学（ｐｈａｒｍａｃｏｋｉｎｅｔｉｃｓ）是应用动力学原理研究药物在体 Applying the system block diagram of modern control theory to the compartment model, the dose-time Laplace transform can be written very quickly. Through the partial fractional inverse Laplace transform to calculate the dose - time relationship, greatly simplifies the understanding of the compartment model, memory and application. Pharmacokinetics (pharmacokinetics) is the application of kinetic principles of drug in vivo
