摘要：

The interrelations between the chemical and biological characteristics of an anaerobic digesting ecosystem were investigated by means of principal component analysis of the linear correlation coefficient matrix of these characteristics. Principal components (factors) were obtained which presented various related characteristics of the ecosystem. The behaviour of the factors during a stress period was graphically demonstrated in relation to time. A three-dimensional model yielded visual representation of the behaviour of three arbitrary chosen factors in relation to each other. The importance of these findings was discussed in relation to the process of anaerobic digestion, and in relation to ecological studies on ecosystems in general. © 1969.
