Methods Taking Grifola frondosa as material, the mycelium was broken by ultrasonic, and then centrifugated, the supernatant was collected, GS was precipitated by different concentrations of ethanol, ammonium sulfate and acetone, the suitable isolation method of GS was researched out by taking enzyme activity and protein content as parameters.
In this paper, Grifola frondosa was taken as material, grifolan synthase was successfully isolated firstly, and its partly enzymatic properties were studied.
MATERIALS AND METHODS MATERIALS Strain: Grifola frondosa, from Fujian Sanming Institute of Fungi.

Architecture is indeed a highly integrated, and almost an all-inclusive set of practical, engineering and artistic as one of the disciplines.
The development of new technologies and new materials continues to emerge in contemporary context.
It involves its own objective status”(Eisenman,1978)We call it the autonomous realm of inquiry.[5] The concerns of the autonomous realm of inquiry are the building construction, materials, structure, and spatial modeling system.
Technological logical thinking corresponds to the construction, relates to the technology, materials, structures and devices.
For example, in late 1990s’ a variety of new materials and new technologies are applied to building skin.

Zinc and cadmium chalcogenides are the key components of II-VI semiconductors.
These materials exhibit direct band gaps of 3.6 and 2.42 eV, respectively, at ambient temperature [9-11].
Thus, our study suggests that Cr doped CdZnS NPs can be used as promising materials to enhance the optoelectronic devices, bioimaging and photocatalysis.

The use of the base course and the selection of base material can be determined by the requirement of bearing capacity, foundation stability, material source and investment conditions etc.
The hardening and paving types of the intermediate zone and road shoulder is decided by these conditions: the requirements of the riding quality, economic conditions, materials source, drainage conditions and structure stability etc.
If the strip roads have a bad hydrological and drainage condition, the cushion is needed or using grain materials which have a good water stability to replace the local subgrade. 2.2 Drainage design Part of the water on the strip roads surface is drained through the road camber, the others permeate into the inner of pavement structure.
In this situation, the drainage state of pavement structure is affected by the backfilling materials, paving style of intermediate zone and road shoulder, base course materials, surrounding terrain and drainage conditions.
It is also better to select the cushion material which has a good permeability.

Introduction Multifunctional oxides are a variety of materials that exhibit a collection of properties and form various degrees of complexity [1, 2].
The results may provide or complement an initial basis of irradiation effect experiments for optimization of parameters or selection of materials, for example.
Oxygen target vacancies are key indicators of defect formation from ion irradiation on oxide thin films.
