目的对生物再生式生命保障系统(BLSS)中的绿藻培养单元——光藻反应器(LABR)的数学模型和计算机仿真模型进行研究。方法运用系统动力学和化学计量学原理,在实验数据的基础上建立LA-BR系统的数学模型,进而建立其仿真模型,进行计算机实验,模拟系统在不同参数下的动态。结果模型的有效性检验表明,本文所建立的LABR的数学模型和仿真模型是有效的,可用于LABR进一步的深入研究。结论通过对LABR模型的仿真实验研究,可以大大减少实际研究所需时间和投入,为对BLSS中的其他子系统的类似研究提供理论和方法上的借鉴。

Objective To study mathematical model and to perform computer simulation for an important subsystem in the bioregenerative life support system （BLSS）, i. e. ,light-algae bioreactor （LABR） for continuously cultivating green microalgae and significantly maintaining life support function of BLSS. Methods Based on the theories of system dynamics and stoichiometry, the mathematical model and simulation model of LABR were respectively established with experimental data, and then computer experiments were conducted to simulate dynamic responses of LABR under different parameters as well as their combinations. Results It was shown that the kinetic model of LABR was valid for its real-life counterpart by a series of verification tests. It could reliably and beneficially provide technical and methodological helps for further investigations of LABR, such as theoretical analysis, design, control and optimization, and so on. Conclusion With computer experiments based on mathematical model and simulation model, it decreases much more in time and money consumption for investigations than with real experiment. This method can also be extended to use in other subsystems studies of BLSS.
