K. H. Roscoe and his fellows of Cambridge University established the first elastoplastic model of soils which is based on classical plastic theory in 1963. However, due to the complexity of soils, the models that based on the classical metal constitutive theory or its modification accounting on the nature of soils have still much limitation when used to express the soil mechanical behavior. For example, the Duncan-Chang's model based on the generalized Hooke's law can not express the dilatancy of the soils. The uniqueness assumption of the direction of the incremental plastic strain in the classical plastic constitutive theory is not in agreement with some soil experiments.

但由于土的复杂性，目前以传统的本构理论为基础考虑土的一些特性而建立的模型在反映土体的力学特性上还存在很大的局限性，如建立于广义虎克定律基础上的Duncan—Chang模型不能反映土的剪胀性，传统的塑性本构理论中认为塑性应变增量方向具有唯一性的假设与一些土体的试验结果不符合。

As an "acceptor", the teachers" professional development will be influenced by many exterior factors, namely the restrictions and limitations, which includes the factors from the society and school which are expounded on from the outside to inside and one tier after another. As a "subject", the impellent of the teachers" subjectivity plays an essential role in their professional development by reasons of the intrinsic factors-teachers" activity, sociality, independence and creativity, that is the teachers" subjectivity in the professional development. As an "object", teachers have obvious characteristics and relatively centralized needs and attention in their development, so the teachers"development is quite different from other professional development in developing phases and training modes, viz, the uniqueness of the stages of the teachers" professional development. The factors analysis connotes two clues. One is the lognitudinal analysis from "acceptor" to "subject", the other is lateral analysis from the "object".

外在影响因素包括社会影响因素和学校影响因素两方面，采用由外向内，逐层递进的考察方式；第二个层面是把教师看作"主体"，教师在专业发展中不只是被动地接受外部的影响，教师本身具有能动性、社会性、自主性和创造性，教师要受到自身各种内在因素的影响，教师专业发展要考虑教师主体性的发挥对自身发展的推动，即"教师专业发展的主体性"；第三个层面是把教师看作"本体"，教师在专业发展中具有相对明显的阶段性特征和相对集中的教师发展需要与教师关注点，教师专业发展作为一种相对独立的专业发展历程，有区别于其他专业发展历程的独特的发展阶段特点和培养模式，即"教师专业发展的独特阶段性"。
