Introduction With such advantageous characteristics as low friction, wide range of speed, good anti-vibration property and long service life, oil lubricated hydrostatic sideways system have become more and more important in precision machine tool technology [1].
According to the mechanical structure hydrostatic slideways has two types of open one and closed one.
One of these is the passive compensation restrictor that adopts flexible or movable element directly affected by the pressure change within the oil-film; the other is the active compensation restrictor that possesses controllable element driven by an auxiliary actuator in accordance with controlling algorithm.
Mechanical Structure Model Hydrostatic slideways support loads by pressuring lubricant oil into a slideways pocket.

Finishing Performance of the Abrasive Flow Machining in Complex Holes by Using Helical Cores A-Cheng Wang1, a*, Ken-Chuan Cheng1, b, Kuan-Yu Chen2, c and Yan-Cherng Lin3, d 1Department of Mechanical Engineering, Chien Hsin University of Science and Technology, Taoyuan city, 32097, Taiwan 2Department of Mechanical Engineering, Chung Yuan Christian University, Taoyuan city, 32023, Taiwan 3Department of Mechanical Engineering, Nan Kai University of Technology, Nantou County 54243, Taiwan aacwang@uch.edu.tw, bkccheng20@gmail.com, cgychen@cycu.edu.tw, dycline@nkut.edu.tw Keywords: Abrasive flow machining, Abrasive gel, Helical cores, Even surface Abstract.
These silicone gels have lower flow property and do not stick on the workpiece surface after contact, so that they are the good abrasive media in AFM.
However, the gap between the hole surface and helical tip is the main factor, which can control the shear forces of the abrasive gel in polishing process.
Helical turn is an important parameter in the complex hole finishing, since it affects the angle of multi-axial motions of the abrasive gel in AFM.

Nano-steels are used in automotive applications to accomplish resource-efficiency while providing high-tech properties.
Nano-steels are a new generation of Advanced High Strength Steels (AHSS), that can provide a combination of properties such as high strength, ductility and hole-expansion capacity, which make them highly suitable for demanding automotive applications [2-4].
The key challenge in the design of Nano-steels is to explore options for suitable alloys with reduced amounts of micro-alloying elements and critical raw materials, while maintaining the excellent mechanical properties characteristic for these steels.
However, apart from precipitation, phase transformation also takes place during annealing, affecting the neutron scattering intensity results directly (different phases interact differently with neutrons) and indirectly through its effect on the precipitation kinetics.

Green construction is a systematic project, which requires the enterprises to establish the idea of sustainable development, modern management and innovation system, to adopt new technologies with better energy saving and environmentally-friendly properties, to achieve construction with high efficiency, environmental protection, and low power consumption, and to enhance the core competitiveness of enterprises.
Other factors leading to the high cost of green construction are the cost incurred in the complexity design which need to integrate green practices into projects, and in the adoption of green technologies which may cause large spent on the new equipment and training for the employees.
Architects pay more attention to the awareness of green construction than project managers, and awareness is evaluated as the fifth importance since it affects the decision making of both strategy makers and consumers.
The scope of incentives should be expanded from developers, building owners, architects and mechanical and electrical consultants to cover the usage of green products and technology which are still very expensive now.

Working temperature of the 2D layered materials can be varied as they possess very high surface area and it vastly affected by the heat treatment during the synthesis process in terms of structure and properties [134].
It was found that, the Fermi level pinning of MXenes was strongly affected by the surface chemistry and the increased in the work function (due to O-termination) then modulates the electronic/transport properties [152].

The oxidation rate is reduced by a factor of two over the whole temperature range.
However, different service environments require different design of the operating materials with respect to chemical and mechanical strength.
Micro alloying has proven to be efficient in increasing the service temperature of high temperature steels in that addition of small amount (less than 1%) of certain elements (often rare earth metals or oxides, reactive elements REs) in the metallic matrix imposes increased corrosion resistance without affecting other desired materials characteristics.
When comparing the oxidation rate for coated and uncoated steel, the presence of a coating yields to the decrease of the oxidation rate by approximately a factor of 2.
Another interesting issue that should be investigated in future studies is the effect that silica might have on the thermal cycling properties of the material.

Change in structural properties due to damage subsequently affects the dynamic behavior of structures.

This network can be used to find out system parameters and unknown factors through the training process, which means it achieves the goal of system identification.

Great differences exist in the mechanical parameters and thermal expansion coefficients between the inclusion and the metallic matrix.
For powder metallurgic (P/M) nickel-base superalloys with high purity, macroscopic inclusions (e.g. oxides) have great deleterious effect on mechanical properties [7-8], and have been removed during the manufacturing, which results in the outstanding reliability.
And the research on the influence of microscopic inclusions on mechanical properties in P/M nickel-based superalloys is not much.
The stress intensity factor range ΔK can be calculated with the crack length a, the load range ΔP, the width and thickness of specimens W and B.
