It contains the content of science and technology, higher contain more cultural connotation, so many reflected in the villa building products. 
While the private garden regardless of size, road pavement is essential, a type of pavement, block material available in different size, material and assembly mode to form, the key is to use what pavement in what place. 
Rockery material has two kinds, one kind is the natural stone material, only in the artificial brick stack, with cement as the cementing material, with concrete as a basis only; there is a mixed cement mortar, steel wire mesh or GRC (low basicity of glass fiber cement) as materials, artificial plastic over molding rockery, also known as "plastic stone", "hill".

Experiment results and analysis The trial use the KP1-type concrete perforated brick produced by Jilin Province Wish flame new building materials Co., Ltd., the material ratio, respectively:cement: 18%;Fly ash:19%; Gangue: 11%;Medium sand: 17%;5 ~ 10 mm in the rubble: 35%,Main block size:240mm×115mm×90mm,Vice-block size: 180mm×115mm×90mm, And in accordance with the testing conditions and requirements GB/T2542-2003 measured intensity level for the batch of brick is MU10.
This is the first attempt to build the wall cracking performance function from the point of fracture mechanics, , the use of K criterion of quasi-brittle materials, to establish the wall formula for calculating the reliability that wall cracks caused by the role of the shrinkage.

Photovoltaic solar modules commonly are attached to some reinforcement materials on the back side of the modules to protect the modules from strong wind.
In the case of bifacial photovoltaic solar modules, sunlight received on the back side reduces because a part of the back side of the module is shaded by the reinforcement materials, and the output of the module dramatically reduces.
It is considered that this approach can also be applied to calculate the output characteristics of every shaded conditions and design of reinforcement materials of the back side of a bifacial photovoltaic solar module.
