Based on the current development of children's electric cars on the market, the design takes human engineering research as the starting point.
The Main Problems of the Existing Products in the Human Factors Engineering Human factors engineering is a new and rapidly developing interdisciplinary, involving a variety of disciplines, such as: physiology, psychology, anatomy, management, engineering, system science, science, safety science, environmental science, etc., whose application field is very broad.
There is no better products from the perspective of consumer health, such as the choice of materials, comfort.
Different materials have different characteristics, and what is important is that the materials influence the realization of the structure and function.

Research On Model of Division of Tender of Engineering: A Minimization Cost Perspective Ling Yan1, a, Qiong Sun 2, b 1, 2 Management School, Tianjin University Of Technology, Tianjin,300384,China b tutsuniqong@126.com Keywords: Tenders Division; Engineering Projects ;Engineering Cost; Model Abstract.
Besides engineering cost, Li Qingmei [1]holds the perspective of tenders division is also one of the key factors to the quality and duration of the engineering.
What’s worse, the method has a bad influence on the whole engineering.
What’s more , tenders division affects the costs of engineering.
Source: drawing according to the research Regard to production costs, to contractors, tenders division has influence on the allocation of construction labor, the materials and machinery and equipment investment and other factors.

The safety of underground tunnels is a key problem of large substructure engineering during excavation and design.
It is also the widest criterion in the stability calculation of underground engineering [7]

In order to make ensure that concrete has good anti-cracking property, volume stability and impermeability, three points of concrete's mix proportion design should be paid attention to: To use cementitious material system with low heat of hydration.
Besides, it should pay attention to key indexes such as the proportion of water quantity, degree of fineness and loss on ignition.
Thus, it is an important work and a key technique of controlling bulky concrete's quality to study how to control bulky concrete cracks.
Key Construction Techniques of the Main Project Construction techniques of pile foundation.
The control of cracks in engineering structures.

At present, the most applications in surface modification of materials is type I collagen, future research will be a variety of surface modification of materials for composite materials, which will play complementary roles, as well as gene therapy and the development of nanometer materials, it will become a hot issue in the field of bone tissue engineering.
Therefore, selecting suitable materials for surface modification, targeted to the matrix scaffold materials for surface modification and surface modification of material surface, improve the cell adhesion and promotes cell proliferation is the scaffold materials for bone tissue engineering research important content.
At present, there is a lot of matrix material used in tissue engineering, which including synthetic materials, natural derived material and composite material.
The importance of bone tissue engineering materials for surface modification The bone tissue can be regarded as a cell of the multiphase composite material from the point of view of material science and engineering.
Therefore, targeted for material surface modification and surface modification of material surface, improve the adhesion of bone tissue engineering scaffold materials research important content.

Study on the Evaluation Method of Engineering General Contracting Enterprises Multi-project Selection Xinhua Wu1,a, Na Tang2,b, Fengzhen Liu1,c 1Department of Resource and civil engineering, Shandong University of Science and Technology, Taian, Shandong province, 271019,China 2 Graduate School of SDUST, Shandong University of Science and Technology, Tsingtao, Shandong province, 266590,China axinhuawu@126.com, btangna2012@126.com, clfz828@126.com Keywords: Engineering General Contractor,Multi-Project Management,Evaluation Index System, Multi-Level Gray Relational Analysis.
Introduction Engineering general contract(EGC), with the development of economic and social and the owners of the comprehensive and integrated service needs is getting higher and higher, in the long-term development process of the construction industry,has been become a reality .In general, EGC should include the whole process of survey,design, procurement, construction and commissioning of the project or several stages of the contracting[1].
A single project management target is not a key factor in determining the developing of enterprises, but enterprise strategic project management target[4].
The key factors of EGCE multi-project selection.Enterprises to choose the project success or not related to future success or failure, and therefore to alternative project in screening, the enterprise according to their development strategy and their own conditions, make scientific project selection basis and method.
Resource is the necessary security factors about the success of the project.When choosing project,enterprises must consider resources which can be provide for the project.In general, including human resources, material resources, and technical ability, financing ability, historical experience and these resources can be obtained effectively by the project.

A comparison of grain boundary engineering mechanisms in copper and brass Valerie Randle and Gregory Owen Materials Research Centre, School of Engineering, University of Wales Swansea, Swansea SA2 8PP, UK V.Randle@swansea.ac.uk, g.t.owen@swansea.ac.uk Keywords: Grain boundary engineering, twinning, electron back-scatter diffraction.
Grain boundary engineering (GBE) has been carried out on copper and brass.
Introduction 'Grain boundary engineering' (GBE), is the manipulation of grain boundary structure in order to improve material properties such as corrosion resistance, intergranular cracking or ductility.
Recently GBE in this class of materials has been reviewed and discussed in detail [1].
It is suggested that these two mechanisms are general for GBE materials.
