For example, manufacturing errors, especially errors of profile and position, assembly errors, nonplanar characteristics of dynamic parameters of components (such as the distribution of mass, inertia forces, etc.), deformation of components, external environments (such as the temperature, the field of the gravity), varying of the condition and so on, all that will disturb the planar constraints, and make it uncertain.

根据广义约束的观点，由于机械的工作受到各种内部和外部约束（包括几何约束、运动约束、动力约束及工作环境条件的约束等）的综合作用，实际上要保证这些约束精确的平面性是不可能的。

Not-deferrable unique constraints and primary keys also use a nonunique index if the nonunique index is placed on the key columns before the constraint is enforced.

In order to study these algorithms systematically and deeply, they are reviewed in this paper based on c-means algorithm, from metrics, entropy, and constraints on membership function or cluster centers. Moreover, the advantages and disadvantages of the typical fuzzy partitional algorithms are discussed.

为了能更为系统和深入地了解这些聚类算法及其性质，本文从改变度量方式、改变约束条件、在目标函数中引入熵以及考虑对聚类中心进行约束等几个方面，对在C-均值算法的基础上得到的基于划分的模糊聚类算法作了综述和评价，对各典型算法的优缺点进行了实验比较分析。
