Therefore, it is not recommended to use the same thickness of fire protective materials derived from prototype’s length, 4100 mm to longer beam.
If there are not proper construction methods or protective materials information, a fire test can be another option to meet it.
Therefore, the fire protection materials got from the fire test with 4100 mm in length cannot apply to longer beam without adding thickness.
According to this result, it should be reconsidered that to use the thickness of fire protective materials derived from 4100 mm in length by fire test into any beams regardless size and lengths of beam.

In this paper, considering the material properties of the composite flywheel and the characteristics of the pre-stressed structure, stresses and strains induced by rotor rotation and interference fit were calculated by finite element (FE) method based on the plane stress hypothesis, in the commercial software ANSYS.
Based on the given material properties and the main dimension with a certain speed of rotation, three 2D FE-models of hybrid composite flywheel rotors with two-layer rotor structure were built with the unit property of plane stress, axisymmetric and plane strain respectively.
Table 1 The physical dimension of the composite flywheel Items E-Glass/epoxy layer Carbon/epoxy layer ANSYS model of the plane stress /plane strain Inner radius/mm 130 160 Outer radius/mm 160 190 Magnitude of interference/mm 0.2 ANSYS axisymmetric Axial dimension/mm 30 30 According to the composite material is anisotropic and the different coordinate system will be used, so material properties must be adjusted to be fit for the analysis of the plane stress model, plane strain model and axisymmetric model .

Currently the United Kingdom to promote passive solar house without external mechanical action, heat-absorbing insulation materials of construction for the media, the use of natural cold and hot air exchange, to the use of solar energy.
It involves the disciplines of Architecture --- urban planning, architecture, building physics (architectural acoustics, building optical, thermal engineering construction), construction structure, building materials, building water supply and drainage, building heating and ventilation, building electrical, landscape architecture, municipal engineering and other professional, it also involves physical geography, meteorology, and environment-related subjects and residents other factors.
Conclusions Residential building energy efficiency is a systematic, not only with architectural planning and design are inseparable, but also to many other areas, such as equipment design, management, application of new technologies, new materials, renewable energy development and utilization, construction division only them into account, can improve the residential building energy saving.

LiOH∙H2O, NH4VO3 and NH4H2PO4 were used as the starting materials.
A stoichiometric mixture of the raw materials was mixed by ball milling for 6 h.
This decrease can be attributed to the large irreversibility of the materials in the first cycle, as shown in Fig. 3.

Rare earth-based AB5-type alloys have been exploited as negative electrode materials in commercial Ni/MH cells, where A is a rare earth and B a transition metal [7,8].Because Co is costly, AB5 alloys of the type La0.7Mg0.3Al0.3Mn0.4X0.5Ni3.8 (X= Co,Nb) with modification in the B part were used for this study.

Their occurrence presages high demands on the durability of the building materials used.
So far, however, cement binder-based materials are most often used.
This is another important argument for the use of secondary raw materials.

Certainly, the teacher also can download courseware for reference and complement each other. 2) Display of multimedia teaching materials The purpose of displaying the multimedia teaching materials is to let students see each martial arts movement’ representation, movement path, direction of body, movement scope, interrelated rhythms and combinations clearly and vividly.
The teacher’s explanation of teaching materials in the classroom makes the teaching means more intuitive and comprehensive.
Only by teachers’ effective control and explanations can multimedia teaching materials achieve its full potential value, and only by stimulating students’ thinking and imagination effectively can multimedia teaching materials achieve the pre-designed teaching objectives.
