On the experience of enterprise energy conservation and emissions reduction in developed countries and the enlightenment to China Jin Lv1, a,JiaLi Liu2,b ,Jing Ma3,c,Peng Liu4,d 1,2,3,4Changchun University of Science and Technology, P.R.China,130022 alvjin713@163.com, b liujiali621@163.com, c majingdoll@hotmail.com, d875295327@qq.com Key words: Energy conservation and emissions reduction, legal system, economy subsidy Abstract: Developed countries have made significant results in the process of energy conservation and emissions reduction.
Then they introduced a series of energy conservation and related laws and regulations, such as “the environmental impact assessment method”, “environmental basic law”, “home appliance recycling container packaging recycling method”, “the basic law of circular society”, “automobile recycling method”, “construction materials recycling method”, and so on.

Royle et al. developed a flow-control restrictor using a spool valve [2] and reported that a hydrostatic journal bearing with their restrictor has much greater load capacity compared with conventional hydrostatic bearings.
To solve these problems, Yoshimoto et al. developed a flow-control restrictor with a small floating disc and reported that the hydrostatic thrust/journal bearings with their flow-active control restrictor using voice coil motors (VCMs) have infinite stiffness under static loads [4,5].
The equation of equilibrium for the bending beam to which an axial load fa is applied is as follows: (5) where E is the Young’s modulus of the beam material, I is the second moment of area of the beam (=bt3/12), z is the co-ordinate in the axial direction and w(z) is the lateral beam displacement.

As there are various types of drawbacks in water pre-treatment processes, and nowadays, the filtration theory and related technologies are relatively mature, we attempt to pre-treat slightly-polluted water by pre-filtration in this paper, with the use of a new type of porous environmental ceramic filter media (whose raw material is red mud manufactured by Shandong Aluminum Company, China), which is developed by School of Materials Science of Wuhan University of Technology, China, and has more excellent properties than that of quartz sand filter [6].

Honey is a sweet product which is brewed in the honeycomb by collecting the nectar of flowers and adding honey bee’s special materials.
The optimum pretreatment method of the spectral data and the optimal modeling band were also determined. 2 Materials and methods 2.1Samples and spectral acquisition Honey samples (147) from six floral origins, namely, acacia, vitex negundo, wild chrysanthemum, wild osmanthus, clover, jujube blossom were obtained from local supermarkets.

Perpetual research work has been done on harvesting energy from vertical heel-strike, particularly with piezoelectric and electro active materials.
However, the piezoelectric materials get senescent under high stress and thus do not produce enough power required for charging mobile phone battery.

In particular, using the MCCB, we demonstrate how we can easily evaluate durability of a product design based on multi-body dynamics and finite element simulation given mechanical properties of materials.
Hence, we modify SM45C through heat treating and design 4 mm diameter latch pin such that we can provide sufficient yield and fatigue strengths for the MCCB given material and size constraints.
The fatigue-life of materials is critically affected by applied mean stresses.

Glass is generally considered to be a chemically stable material at the normal conditions.
Chemical character of the cords is on the basis of the silicon, aluminium and zirconium that release into glass melt from the surrounding refractory material into a glass melt in the melting region (high temperature) and in the forehearth channel ended by the outflow bowl (low temperature region).

Two methods are generally used to improve the corrosion and wear resistance on the surface of materials or parts.
The Fe-14Mn-6Si-5Ni alloy is selected as the experimental material, which is chemically composed of 15.52% Mn, 5.47% Si, 4.03% Ni, and 74.98% Fe according to the mass fraction.
The industrial pure iron, electrolytic ferromanganese, silicon, micro-carbon ferrochromium, and electrolytic nickel are selected as smelting materials to produce an alloy in a vacuum ZG-0.025-type silicon controlled rectifier (SCR) intermediate-frequency induction furnace.
