The starting point of establishing rules and forms of Chinese classical poetry includes the exploration of rhythm and the use of level and oblique tones.

The following evolutionary laws should be adhered in the .

Traditional legal evolutionism is developed on the basis of criticizing pure rationalism of structuralism,which mostly degenerates the function of reason.

Theories of Luhmann—structural functionalism,legal evolutionism and auto production of law—have great inspiration to the study of law and legal construction in our country.

Effect of sodium tripolyphosphate on the hydration process,ion concentration and supersaturation degree in liquid phase,and crystal morphology of building gypsum was systemically investigated.

By testing hydration rate and hydration temperature at different times,the effect of the retarders on the hydration process of calcined gypsum was studied,and by analyzing morphology and pore structure,the effect of the retarders on the microstructure of gypsum was also studied.

The influence of sodium sulfate on the anhydrite hydration process and the crystal morphology of its dihydrate products were studied by the determination of the hydration rate, hydration temperature and the ion concentration in liquid phase, in combina-tion with the investigation of the microstructure of the hardened anhydrite paste.
