Introduction Environmental engineering is an emerging discipline which is the multidisciplinary combination of science and engineering.
There are many basic courses such as engineering mechanics, material mechanics, fluid mechanics, hydraulics, surveying, chemical principles and environmental engineering principles [3-5].
The curriculums were adjusted to engineering mechanics, fluid mechanics, hydraulics, engineering drawings, electrical engineering, environmental engineering principles, chemical principles, environmental monitoring, environmental engineering and environmental biology.
The students look up materials according to the title and needs, and draw up practical experimental program, at last carry out the amended plan.
For example, the environmental engineering of Xi'an Architecture and Technology was set up on the base of ministry of education’s northwest water resources and key laboratory of environmental and ecological engineering.

It has theoretical significance and practical engineering value to systematically investigate incremental launching construction control key technologies of inclined continuous beam.
Engineering characteristics Liuyang River Bridge is a “class double-layer” prestressed concrete continuous box-beam bridge with incremental launching construction.
The configuration of guide beam should choose lighter materials.

Piezoelectric Actuators 2008: Key Factors for Commercialization K.
For the tape-casting equipment, the initial investment (fixed cost of equipment = $300K) is expensive, with a low slope of variable cost (just raw materials cost) as a function of production quantity.
On the other hand, the cut-&-bond process requires a steep slope of variable cost provided by the labor fee in addition to raw materials cost.
Artistic sense should be added in the device development (Sci-Art [13]) in the 21 st Engineering Renaissance era.
On the contrary, the strategy of "differentiated product" with prestigious price is the norm in the bio- and medical engineering field.

Discussion on the Sound Radiation Coefficient of Building Materials Yan Yang a, Xianfeng Huang b and Jun Liu c Key Laboratory of Disaster Prevention and Structural Safety at Guangxi University, Ministry of Education & College of Civil Engineering and Architecture, Guangxi University, Nanning 530004, China a774969688@qq.com, bseulee@163.com,c294746901@qq.com Keywords: sound radiation coefficient, building material, sound insulation Abstract.
Due to influence of radiation on the sound transmission in a structure, sound radiation coefficient plays a significant role on the option of sound insulation materials during the practical engineer.
The Radiation Efficiency of Different Building Materials Some common building materials are used to calculate the radiation efficiency with 1/3 octave band center frequency.
The critical frequency of the same materials decreases with the thickness of a wall.

Foam lightweight soil is a new type of material appearing in recent years, whose advantages are paid more and more attention to by engineers and it will have broad application prospect in the engineering.
Higher rate of bubbles in the finished foam lightweight soil, the volume of the finished product up to more than three times the volume of raw materials, thereby the delivery rate of construction materials is increase [4].
Key points of construction process.
It is good to meet the demands of different density for engineering
The foam lightweight soil as a new type of lightweight materials will have broad application prospects in engineering practice.
