Abstract.
One of the most key factors is the cost.
They include plan costs, quality inspection costs of materials and products and after-sales service costs.
Firstly, guided by green production, the enterprise is through implementing lean production and performing value engineering analysis to reduce useless functions costs, and through technology innovation and improving labor efficiency to economize the artificially costs.
The indirect costs include plan costs, quality inspection costs of materials and products and after-sales service costs

Changes of the concentration of TP after the engineering of dredging are the focus in this paper.
Never could it be enough to recover clear state of a lake only by dredging the sediment, actually, which has been resulted from many unsuccessful dredging engineering in China in last decades.
On the other hand, dredging engineering get more attention in China because of some advantages such as reducing disaster, increasing environmental capacity, and prolonging the lake life(ZHONG et al., 2009).
Materials and Methods All of this research is to solve the problem how the key nutrients -- including TP, TN and TC will progress in Cihu Lake water polluted by TP emergently.

On the interface of dissimilar materials, the compound plane is reinforced by a collinear system of absolutely rigid thin inclusions and is subjected to mechanical and thermal influences.
As a result, local stress fields with large gradients are formed around the stress concentrators of these types, which significantly affect the durable characteristics of engineering structure, in particular, building and machine-building structures in general, and their parts separately.
Due to the theoretical and practical importance of temperature stresses in the calculations of engineering structures, containing stress concentrators of the type mentioned above, large-scale studies have been carried out in this area of thermoelasticity.
Here are the coefficients of linear thermal expansion of materials of the half-planes ; are their coefficients of thermal conductivity.
Fracture mechanics and strength of materials.

Carbon nanotube (CNT) study was firstly published by Iijima in 1991.[[] S.
With the large-scale production of carbon nanotubes, their applications are more and more in all kinds of engineering materials and sensors.
Smart Materials and Structures, 18 (2009) 055010. ], from university of Minnesota, studied the piezoresistive properties of CNTs cement-based composite materials.
These studies provided important theoretical basis for the application which MWNTs cement-based composites were used as stress sensors in civil engineering.
The homodisperse of CNTs become the key issue to promote them practical application.

Abstract.
However, DEFORM-3D built-in material database has the defect that often encounters the materials not needed or the disunity of alloy brand, which seriously hinders the application of finite element simulate software in the engineering project.
It is widely used in machinery, vehicle, shipping, bridge industry and some welded structured in cryogenic engineering machinery.

Keywords: Finite element method, Robust design, Steering mechanism, Lock force, Monomial cubature rules.
Steering mechanism is an important part of car driving system and the lock force is a key parameter to protect driver in the case of a frontal impact.
The advantage of the method is to reduce the intensive computational demand of uncertainty propagation by construction of PCE using points of MCRs, and the accuracy is enough for engineering problems.
Both the yield stress of the material and the friction coefficient follow a probabilistic distribution.
