In terms of a stabilizing agent for road rehabilitation and construction, many research studies have confirmed that the properties of GP are similar to that of Portland cement [7].
The basic properties are 130 minutes of initial setting time and compressive strength test more than 40 ksc, which reach the ideal grading curve for geopolymer production by CR.
Based on the emission factors of materials are listed in Table 3.
The emission factors of CR is 0.0045 Kg CO2-e/kg.
Size of crushed rock significantly affects the properties of CR-GP.

Although complicated control of parallel mechanism is avoided and development costs can be reduced with this mode, intended functions of CMM can not be fully realized. 3) As 1st slider and 3rd slider can not be complete stretched with 1000mm precision guide, the space of z<280mm can not be reached by probe, the actual measuring space is less than the scale of theoretical and unable to fulfill the expect technical indicators. 4) During measuring process there is interference in cardanic joints, and existd a larger clearance, measuring accuracy is difficult to get assurance. 5) It is irrational in material selection of key components of prototype and weak in the mechanical properties of overall, especially the mechanical deformation of beam and precision guide directly affect the measuring accuracy of CMM.
Schematic diagram of parallel mechanism CMM In order to enlarge the measuring space of CMM, improve the measuring accuracy and mechanical properties of CMM and flexibility of moving platform, structure of new prototype with active motion were optimization designed according to the structure parameters of previous one.
The beam is the key mechanical component of CMM and equipped with precision guide and grating, its deformation directly affects the measuring accuracy of the instrument.
The bar module is consisted of 2 cardanic joints and a carbon fiber connecting bar; cardanic joint is made from alloy steel and the material properties of connecting bar is as follows: modules is 3×105MPa, Poisson ratio is 0.25 and density is 1800kg/m3.
The key structure parameters of CMM and poses of cardanic joints were optimization designed; the measuring space of new prototype is 1050mm´535mm´426mm and enlarge 92% measuring space in x axis, 134% in y axis and 113% in z axis compared with the previous one. 2) The deformation of the key components are analysed by FEM, and the basic mechanical properties evaluation of the prototype is completed: the maximum deformation of beam δ1max is 61.86μm, and 0.778μm of the maximum δ2i.

Such two-phase structure usually improves their mechanical and ultimate properties.
Investigation of synthesis and physical properties of mainchain LCPUs prepared from LC diisocyanates and/or LC diols by polyaddition reaction have been reported in literature [4-8].
In order to get the LC properties, Finkelmann et al. [9] have suggested that it is necessary to decouple the main chain motion from the mesogenic group by a long flexible spacer.
Most complex thermal properties were found for polymers based on D4 diol; e.g. for D4/TDI polymer two LC transitions were detected. b) Dynamic mechanical measurements during the curing reaction of three component systems show that the power-law parameters, which characterize the critical gel (CG) state (gel strength S and relaxation exponent n), depend on the initial composition and used triol.

Assume that the woven lamina has anisotropic materials properties and the unidirectional lamina has the transversely isotropic material properties.
Since the ply angle leads to different sectional mechanical properties along the width of the π-joint, a 3-D finite element model is established to investigate the failure mode associated with the π-joint by means of software ABAQUS.
Thus the geometric parameters, such as vertical support length, horizontal support length, preform thickness and radius of filler, are major factors in the design of a composite π-joint.
As the filler radius increases, the strength ratio in the filler decreases sharply, which indicates the filler radius affects the load transferred through the filler significantly.

Because of its large size, weight and other factors of the components, resulting in the installation process, some tools such as a bracket and screw with the light bar and other parts of natural distortion, so the gravity beam deformation is moving gantry CNC milling machine an important source of geometric error one[1].
Then the beam weight and gravity headstock torque M produced by the joint action makes the beams deformed, the deformation of the beam will directly affect the on-site precision, so the beams as the main object of study, Beam by the force diagram shown in Figure 2.
In this paper, the two main factors is attentive in the meshing : first, meshing be divided by the software automatically and combination with human involvement to complete, which will improve the classification efficiency.

The main advantages of so called nanocompounds are their - in comparison to microcompounds - outstanding mechanical, thermal and electrical properties.
It is well known that their mechanical and physical properties of semicrystalline polymers are governed by supermolecular morphology, which is controlled by the respective crystallization process.
To know, how nanoparticles affect the crystallization behaviour and the question where they are located in the polymer structure is a key factor for explaining the possible effects of the nanoreinforcements and their extraordinary influence on properties already at low filler contents (< 5 vol.%).
This material was chosen as a representative of polyolefins, which are the most common used thermoplastics due to their well-balanced physical and mechanical properties, easy processing and recycle characteristics.
In addition, in comparison to other engineering thermoplastics, PP has a lower density, allowing potential weight reductions along with excellent moisture barrier properties and good optical properties due to its higher crystallinity [8].

And the semi-solid micro-structure was affected by these two critical parameters, the pouring temperature and CRS process.

Fig.2 20MN fast forging hydraulic system forging motion curve 3.2Analysis of the accumulator absorption process during hydraulic shock The effect of hydraulic shock absorption of the accumulator in system associates with many factors, such as the quality of oil in the accumulator and pipelines, structure parameters and state parameter of accumulator, pipeline characteristics, the characteristics of loop components and flow pulsation frequency etc.

The P-E hysteresis loop of BT-1Fe-1.5Nb under the stress of (a) 0 MPa (b) 185 MPa To explain the experimental results on the decrease of the ferroelectric properties with increasing compressive stress, as shown in Figs. 1, 2, and 3, one can interpret the changes by exploiting the domain-reorientation processes.
However, it is also noticed that the aging rate seems to be affected slightly by the compressive stress.
The mechanism of this enhanced aging is not clearly known, but could be due to lowered activation energy for defect-dipole motion with external mechanical load.
In addition, the aging rate is not strongly affected by the applied stress in donor-dominant hybrid-doped BaTiO3 ceramics, as seen in Figs. 2 and 3.
