摘 要: 采用定性與定量相結(jié)合的方法對(duì)生物冶金中微生物系統(tǒng)在金屬浸出過程中是否形成耗散結(jié)構(gòu)進(jìn)行分析，并對(duì)生物冶金中微生物系統(tǒng)的演化過程進(jìn)行推演。結(jié)果表明：生物冶金中微生物系統(tǒng)具備耗散結(jié)構(gòu)特征，因此，生物冶金中微生物系統(tǒng)滿足耗散結(jié)構(gòu)的開放系統(tǒng)、非線性關(guān)系、遠(yuǎn)離平衡態(tài)和漲落的四大條件，生物冶金中微生物系統(tǒng)在金屬浸出過程中存在耗散結(jié)構(gòu)；對(duì)生物冶金中微生物系統(tǒng)進(jìn)行了演化，得出了生物冶金中微生物系統(tǒng)演化過程圖，系統(tǒng)最終會(huì)自發(fā)地發(fā)展到穩(wěn)定態(tài)x*=(k-d)/β，其中k-d越大，飽和系數(shù)β越小，這個(gè)穩(wěn)定態(tài)數(shù)就越大，越有利于微生物金屬浸出。

Abstract:A combination of qualitative and quantitative methods was used to analyze whether the microbial system in biometallurgy forms a dissipative structure during the metal leaching process, and the evolution of the microbial system in biometallurgy was deduced. The microbial system in biometallurgy has the characteristics of dissipative structure. Therefore, the microbial system in biometallurgy satisfies the four major conditions of dissipative structure: open system, nonlinear relationship, far from equilibrium and fluctuations. The microbial system in biometallurgy has dissipative structure in metal leaching process. There is a dissipative structure in the leaching process. The microbial system in biometallurgy is evolved, and the evolution process diagram of the microbial system in biometallurgy is obtained. The system will eventually develop spontaneously to a new steady state x*=(k-d)/β, Where the larger the k-d, the smaller the saturation coefficient β, and the larger the steady-state number, which is more conducive to microbial metal leaching.
Key words: biometallurgy; microbial system; dissipative structure characteristics; evolution
