Microalgae are considered to be a promising biofuel resource for carbon dioxide fixation in the future. Modeling the growth of microalgae is an effective method to study the growth performance of microalgae, which is also helpful to control the cultivation of microalgae in artificial bioreactor. In continuous culture, dilution rate and influent inorganic nitrogen concentration have shown significant effects on the growth of microalgae. In this paper, the common and overall influences of dilution rate and influent inorganic nitrogen concentration on the microalgae growth have been investigated. Based on numerical simulation, this paper plots the results of total and unit time particulate carbon concentration in 3D figures to expose the varied tendency. It is found that the value of points on the ridge line increases with the dilution rate decreasing and influent inorganic nitrogen concentration increasing for both the total particulate carbon concentration and the particulate carbon concentration per day. The influence of several typical temperatures has been modeled and calculated. The value of biomass productivity will be further increased when the dilution rate is getting closer to 0. This paper will go a step further for the parameters design of continuous culture photo-bioreactor (PBR) for later study.

模拟连续培养中的微藻生长：参数分析和温度依赖性

微藻被认为是未来固定二氧化碳的有前途的生物燃料资源。对微藻的生长进行建模是研究微藻生长性能的有效方法，也有助于控制人工生物反应器中微藻的培养。在连续培养中，稀释率和进水无机氮浓度对微藻的生长有显着影响。本文研究了稀释率和进水无机氮浓度对微藻生长的常见和整体影响。本文在数值模拟的基础上，以3D图形绘制了总和单位时间颗粒碳浓度的结果，以揭示变化趋势。结果表明，无论是总颗粒碳浓度还是日颗粒碳浓度，脊线上的点的值都随着稀释率的降低和进水无机氮浓度的增加而增加。对几个典型温度的影响进行了建模和计算。当稀释倍数接近于0时，生物质生产力的值会进一步增加。本文将进一步研究连续培养光生物反应器（PBR）的参数设计，以供后续研究。
