Given this assumption, even if the parameters of the system are randomly perturbed, by either genetic mutation, environmental variance or experimental manipulation during development, the system will generate a limited and discrete subset of phenotypes. Thus the realm of possible forms is a property of the internal structure of the system.

而在这种假设的前提下，即使系统各参数值受到发育过程中的随机扰动（或者是遗传突变，或者是环境变化或人工实验操纵），系统会产生出某个某个有限的、离散的表型[11]子集，因此，生物可能形态的王国，其疆域从属于生命系统的内在结构。

In order to understand and know about the basic principle and quantification relationship of greenhouse phalaenopsis during vegetating phase and forecast the dynamic action of vegetation system so as to assist reasonably regulating and controlling on the vegetation and production system of phalaehopsis real time, a dynamic vegetation model of greenhouse Phalaenopsis is created on the solar radiation as the basic driving factor and a computer simulation system is developed on Windows XP system.

为了对温室蝴蝶兰生育过程的基本规律和量化关系有一个清楚的理解和认识，并对其生长系统的动态行为进行预测，从而辅助进行对蝴蝶兰生长和生产系统的适时合理调控，研究建立了以太阳辐射为基本驱动因子的温室蝴蝶兰生长发育动态模型，进一步开发出基于WindowsXP的计算机模拟系统。

This thesis has systematically dealt with the glacial, lake and climatic fluctuations in the areas mentioned above throughout the late stadial of the Last Glaciation, based on synthetical records of glacial development at the high mountains, lacustrine stratigraphy and lake evolution in both the high plateau basins and the lower altitude interior ones, periglacial phenomena and palaeosols as well as microfossils in deposits.
