查询词典 perturbation method

The disorder contained can only cause the complexity in the organization, disorder outside organization has the influence to organization complexity, but it cannot cause the organization the complexity, only if it is absorbed and in the organization, can the disorder constitute the complexity; all nature of the complexity is produced because of the disorder in the organization, if there is no the disorder, the organization has no nature such as fortuitousness, randomness, multiplicity and non-linearity, and it is impossible to appear the perturbation, the fluctuation, emerges with phenomenon such as branch, and cannot change suddenly and evolve.

无序只有包含于组织中才能够导致复杂性，组织外的无序对组织的复杂性产生影响，但它不能导致组织的复杂性，只有被组织吸收，成为组织内的无序，才能构成复杂性。复杂性的所有性质都因包含于组织中的无序而产生。没有无序，组织就没有偶然性、随机性、多样性和非线性等性质，就不可能出现扰动、涨落、涌现和分岔等现象，就不能突变和进化。
