In order to disclose the adaptive strategies and capacity of Potaninia mongolica Maxim, acquired during its evolution history, the whole response system, which was composed of individual morphology plasticity response, organs anatomy structure response, physiological function response of anti-arid and anti-hotness, activities of protective enzymes response, endogenous hormone adjustment response, sexual reproduction strategies response of seeding, dispreading, sprouting and renewing, asexual reproduction strategies response of clonal growth patterns, clonal growth architectures, clonal growth architectures plasticity, heterogeneous resources utilization strategies, endogenous hormone distribution in clonal organs, foraging behavior, risk-spreading, and resource sharing, individual density allocation patterns response, niche differentiation response, species connection response, allelopathy response and biodiversity components response of the plant was profoundly explored in this paper.The studies come to at least four important results:(1) Taking the sensitive response and evading strategy to adapt to environment stress, Potaninia mongolica Maxim is a successful species has lived through the long-term evolution. Nevertheless, it is narrow climate and soil niche and characteristic of vegetation reproduction which has made the plant a rare and endangered species.

Compared with ordinary quartz, owing to nanoscale alumina crystallite, the artificial stone made of TISM nanoscale microcrystallite quartz can stand higher temperature (as high as 800℃ instantly), become harder (reaching 6 according to mohs hardness scale), and enjoy better plasticity because of nano alumina crystallite's good mouldability.

帝斯曼TISM纳米微晶石英石同普通石英石相比，由於增添了纳米氧化铝微晶粒子，整体板材更耐高温（暂态耐温度可达到800摄氏度以上），硬度更大（莫氏硬度达到6以上），同时结合纳米氧化铝微晶粒子在抗拉伸疲劳中出现可塑性形变的特点，所以整体板材相对于普通石英石韧性更好、可塑性更高，更不易开裂。
