And through the test of thermal-insulating of the material and mechanical properties, the relation equations between vitreous micro-bead content (the main agent of thermal-insulating material) and thermal conductivity, uniaxial compressive strength, confined compressive strength have been obtained respectively.
Taking into account the vitreous micro-bead is the main factor in thermal insulation factors, followed by cement intensity, the various auxiliary materials are made into additives.
The factors–level table is shown in Table 1, and the orthogonal test arrangement is shown in Table 2.
According to combine the primary and secondary order of the above influence factors with the best horizontal, the more excellent program could be put forward after a comprehensive comparison and analysis about the factors’ test results.
And it has seriously affected the workers’ operation and environmental safety.

Beneath the recast layer, a heat affected zone is formed.
The microstructure and the properties of the melted zone after solidification are quite different with respect to those of the workpieces and tool electrodes used in the process [4,8].
There are many process variables that affect the surface integrity such as pulse duration, peak current, open gap voltage, electrode polarity, material properties of the tool electrode, workpiece and dielectric liquid, debris concentration and even size of the electrode [3].

The tensile strength of joints depended on these factors.
In general the diffusion bonding method in vacuum with active solder was selected in this joint system because of the much difference of mechanical and physical properties such as melting point, thermal expansion coefficient, Young's modulus.
Bonding temperature, bonding duration time and bonding pressure were investigated as the experimental factors to obtain the suitable bonding conditions in the PECS method.
It indicate that the interface strength increased with the increasing the bonding temperature, but the residual stress affected to the strength over 753K.
It assumed that the following factors affects to this case on the distribution of bonding strength for the sliced butt shape specimen

Based on the analysis of support effect under original support design at Hongmiao Colliery, the paper summarized the main factors causing the destruction of roadways under neighboring gob areas, and pointed that the low pre-tension of the former support system and the irrationality of auxiliary support components were the main reasons for the failure of roadway support.
They showed some properties, such as the low strength, loose and cracked, easy weathering, easy disintegration, water-swellable and etc.
They seriously affected the normal production of the coal mining face.

Silk hydrogels have mechanical properties and structural features that are similar to load-bearing soft tissues, and can be implanted for tissue restoration.
Introduction Silk fibroin (SF) protein, as a nature polymer, exhibits impressive mechanical properties as well as biocompatibility.
Especially injectable SF hydrogels, which have mechanical and structural properties similar to some tissues and extracellular matrices(ECM), have good effect in bone defect repair[2-3].
Understanding the inherent mechanism and the related factors is important for improved handling of this unique protein.
The particle size of initial solution may affect the silk fibroin gelation.

Introduction It is well known that PP has excellent comprehensive mechanical properties, but PP’s defects, such as slow crystallization rate, poor low temperature impact performance, and large shrinkage from mould dimensions, limit its wider application in different fields.
It indicates that adding few of s-PB can affect PP’s crystallinity significantly.
However, the influence factors are complicated to crystallization and melting behaviors of PP in blends.
Many factors intercept crystalline PP in blends.

This lead to a fact that the impact force was not affected by the change of the reinforcement ratio, but mainly affected by the change of the slab thickness.
This model's mechanical behavior is a continuum concrete damage model, based on plasticity.
Concrete materials properties.
The interaction between the impact load and the concrete slab is defined by the (explicit) surface-to-surface contact available in ABAQUS / Explicit [7], the mechanical constraint formulation kinematic contact technique was active in describing the selection of contact properties.
Obviously, the load-time history is not affected noticeably by increasing the reinforcement ratio.
