With the development of modern science and technology, system science and systemic theory and method have applied in IE, and IE has already enlarged its fields in service industry, public utilities and even government departments[1].
Expand Students’ Knowledge Scope According to the curriculum content, the teachers appoint some representative books as the expansion materials which promote students to study actively, deepen the students' understanding of the course and understand the situation of academic frontier development.
It has two styles: 1) List Auxiliary Materials.
Through the course notes of “Systems Engineering”, the relevant case materials of the course will be introduced to broaden students' view.
Conclusion At present, systematic research is the leading direction in the world, and modern IE has already been the science of interdisciplinary integration and optimization.

Unlike bulk materials, nanometer-sized clusters can exhibit various structural patterns, including truncated octahedral, icosahedral or decahedral structures with 5-fold symmetry characteristics, and even amorphous clusters.

Material parameter.
The material for tunnel lining is concrete.
The specific material parameter is showed in Chart 1.
The dynamic elastic modulus of the material can be increased by 30% on the basis of static elastic modulus.
Calculation results The model’s damper ratio is taken as 5% in dynamic analysis, and the dynamic elastic modulus is adopted for all materials.

Introduction to Composite Materials.

Since it is obvious that dislocations are the main reason for degradation in power devices the prevailing attention has also been shifted to that field of material research.
KOH-defect-etching, electron microscopy and optical microscopy, to evaluate resulting material properties.
Based on the latter we were able to adjust the specifications of raw materials.

According to the survey, almost all the universities that have set up civil engineering major failed to open safety science and technology courses.
From the perspective of the content of courses, overlapping can be easily found in the courses above, and the teaching materials in each university are mostly adapted by themselves, with distinctive style, even the different courses in one school have reiteration and conflict in many parts.
Suggestions that are oriented to the engineering safety curriculum content in the field of civil engineering can be described as follows. 5.2.1 Outline I will conduct my exploration from the safety and safety science and technology, safety science promoting scientific development of science and technology, the basic connotation of construction safety management, safety production conditions and management around the world.
