传统的生物对象是通过宏观物理的方法来描述的，但动力学的方法使我们能够更深入地了解生命系统的本质。对动力学方程提出了一个特殊的问题，以模拟与局部非平衡态有关的生物系统的基本特征。生物系统被视为“喂养”负熵的耗散结构，非平衡开放系统的分布函数表示的统计熵支持这一观点。作为开放系统的空间非均匀非平衡分布的区域的生物结构的大小进行了估计。这些评价进行了比较与经验证据的依赖性的大小的哺乳动物和绿色叶的新陈代谢的强度。
Traditionally biological objects are described by means of methods of the macroscopic physics, but the kinetic approach allows us to understand deeper the essence of living systems. A special problem is formulated for the kinetic equation to simulate the basic features of the biological systems related to local nonequilibrium states. The biological system is treated as the dissipative structure which "feeds" the negentropy, and the statistical entropy expressed through the distribution function for the nonequilibrium open system supports this viewpoint. Sizes of a biostructures as the regions of spatially nonuniform nonequilibrium distributions of the open system are estimated. These evaluations are compared with empirical evidence concerning the dependence of the sizes of mammals and green leaves on the intensity of the metabolism.
