A key for this strange temperature dependence lies in the number of trapped H atoms, r, which varies from r ≈ 6 for full occupation at low temperatures to r ~ 6x for random occupation at high temperatures.
In ordinary materials, as vacancy sources are prevalent on dislocations and grain boundaries, a time needed for Vac-H clusters to attain thermal equilibrium should be shorter.

If any city attempts to give people a deep impression, the key point is its regional characteristics and humane features.
Urban culture is proposed as the sum of material and spirit treasure which people have created during the process of city construction.
As a part of traditional culture, idioms have been integrated into local culture to ensure the continuation of regional culture by utilizing structural modal, urban texture, materials and technologies.
Therefore, we should pay attention to not only material category but also spiritual category when discussing the landscape design and urban style.

Key words: Hsian-tsao, Polyphenolic compound, Antioxidant activity, Abstract: Extraction and purification of polyphenolic compounds from Hsian-tsao (Mesona procumbens Hemsl.) were investigated.
Different solvent systems have been used for extraction of polyphenolic compounds from plant materials[5,6], but it was still not clear which solvent systems were more effective to extract polyphenolic compounds from HT plant.
Material and Methods Material The dried HT purchased from local market in Jian ou, Fujian province, was cut into pieces and groundded into fine powder in a mill.
