The insulation material of the contact of breaker B phase external operated at high temperature, and produced a certain amount of smoke and dust, these spread upward.
But because the flame retardant performance of insulating material is poor, so led to the aluminum alloy parts of hand car burning solution.

The emerging science of grain boundary engineering (GBE) strives to alter the boundary network to optimize properties such as corrosion resistance [1], critical current density [2], and strength [3].
Because CMs influence a broad variety of material properties, identifying and characterizing them is an important challenge in 3D materials science.
Journal Title and Volume Number (to be inserted by the publisher) 5 In the mixed regime, the CM cleaves unfavorably oriented grains and goes around favorably oriented grains.
Conclusions A number of material properties depend on the characteristics of the three-dimensional grain boundary network.

With the development of the concrete admixture, the application of superplasticizer had been more and more popular, this greatly improved the fluidity of concrete and made the concrete pumping easier, but on the other hand, the poor adaptability to raw materials and the cabined dosage of superplasticizer also increased the risk of segregation to the concrete [2,3].
Test and analysis Raw materials. (1) Cement: PO42.5 ordinary Portland cement was produced by HuaXin corporation, its technical performance was listed in Table 1.

A multidimensional analysis code for reactive shocks (MARS), which is developed to solve various problems in the physical hazard analysis of high energetic materials, has been applied to such complex problems as multi-material problem and sympathetic problem because it can employ various types of equations of state and a materials database.
MARS has many models of materials including various explosives, and employs equations of state (EOSs), and various burn models such as ignition and growth models.
The shock from an explosion of donor explosive propagates through a gap material, which is a known material and has a certain thickness, and impacts on the receptor explosive.
In the test In this case, both the donor and receptor charges are Composition C4 explosives and the gap material was mortar with 6m thickness.

Introduction One reason for the premature failure of asphalt pavement structure is due to rainwater through pavement seams,cracks and segregation of the road into the internal structure,this will form hydrodynamic pressure under vehicle load and scour pavement structure then reduce the performance of the pavement[1,2].To eliminate early water damage,at home and abroad in the design of the pavement structure set internal drainage system[3,4].At present commonly used permeable base materials are cement treated aggregate and porous cement[5].Porous concrete also be called macroporous concrete or porous lean concrete.As a new base drainage material,compared with cement treated aggregate,porous concrete has higher cement content,none or less fine aggregate,higher strength and permeable ability[6].To study the construction technology of porous concrete permeable base and the using effect,the paper is based on southwest beltway Luohebei interchange ramp project in Luoyang,Henan,which paves test
The pavement structure and drainage base edge structure design as shown in Figure 1.Materials in gullies and base are the same,the are all porous concrete and with same mix.The longitudinal manifold using 10 cm in diameter of the strong permeable tube,and its longitudinal grade should be same with the route longitudinal gradient,not less than 0.25%.At the same time, PVC horizontal pipe spacing of about 50m settings without holes, the diameter is same with water collecting pipe,and water collecting pipe gradient should not less than 5%.The tack coat and prime coat use the same material with production sections.And set up seal coat between porous concrete permeable base and cement stabilized soil.
Fig. 1 Schematic diagram of pavement structure and permeable base’s drainage system’s edge structure Mix design of porous concrete Specifications of raw material Aggregate On account of porous concret with low cement content,and it belongs to the open graded skeleton void structure,The entire structure’s weakest strength depends on the the bonding strength between cement and aggregates.So the aggregate shall be hard and clean, crushing value should below 30%,mud content is within 1%,and the acicular content is not more than 15%.In the test section The aggregates under construction are into 10 ~ 20mm and 5 ~ 10mm two section,these technical indexes as indicated in Table 1, and meet the requirements of specification.
In actual construction,the mix should be adjusted according to the material water content.
