Introduction Silicon carbide (SiC) is a suitable material for power devices because of its superior physical properties that include a wide band gap, high electric breakdown voltage, high thermal conductivity, and a large saturated drift velocity [1].
The dislocation conversion phenomenon is a key process for high-quality SiC growth.

Thus, the quantity of the shear walls can be obtained by the formula (5): (5) Research on feasibility of the shear wall setting in the bottom weak layer Combining the theoretical analysis with actual engineering, we find it feasible that the shear wall’s setting scheme determined by specific theoretical calculation and the shear wall setting’s preliminary confirmation in the bottom weak layer by PKPM modeling.
The size of basic components and materials used is shown in Table 1: Table 1 scantling and material list Component Section size Materials Modulus (KN/㎡) Beam 0.3×0.65㎡ C30 30×106 Column 0.60×0.60㎡ Filler walls External wall 0.25m MU10 Mb10 4.743×106 Interior wall 0.20m (2) Defining the shear wall’s setting scheme The frame filled wall structure’s lateral stiffness is calculated as shown in Table 2: Table 2 lateral stiffness of frame filled wall structure Layer (KN·m) (KN/m) (KN/m) (KN/m) External wall Interior wall External wall Interior wall 1 124000 1188560 13367806 0 2673561 0 2~8 124000 1188560 13367806 15625577 2673561 3125115 In order to improve the stiffness abrupt change between the first floor and other floors, it can add a certain number of shear walls in the first floor, and calculated the quantity of the shear walls in Table 3.
Model 2 is the frame filled wall model: the key of this model is re-converted the section size of columns by the principle of equivalent stiffness, translate the frame filled wall into the equivalent pure frame before modeling and analysis.

Therefore, it is significant to establish a multi-level, multi-factor, multi-objective systematic engineering for energy-saving assessment which requires appropriate assessment techniques to achieve the scientific, efficient, reasonable and comprehensive evaluation on architectural design scheme.
For the former, starting from government office buildings, energy conservation transformation is expected to be implemented to form typical and outstanding engineering cases.
Building Energy-Saving Materials.
Architectural planning and design stages therefore ought to consider energy-saving ideas, use appropriate technology and appropriate materials [20], so as to avoid over-dependent to high energy-saving technologies and energy-saving materials.
Compared with conventional wall materials, coefficient of heat conduction of energy-saving wall materials is significantly lower, that means a great reduction of indoor heat loss.

Active ingredient, filler and biopolymeric matrix are mixed to form biodegradable biocomposite packaging materials, which are joined by covalent or noncovalent bonds.
Materials and Method Materials.
Bruker D2 Phaser X-ray diffractometer with Cu Kα X-ray was used to analyse the crystalline structure of the materials.
