Again, engineering ceramics may be the materials of choice based, but their brittle nature, poor machining properties, and cost severely limit their widespread utilization as monolithic components.
Joining of Engineering Ceramics with Metallic Materials Studies [10] on brazing SiC with reactive metals foils containing Ti showed that the Liquid metal/ceramic reaction intensifies as the melting point of the filler metal is increased.
Wood is known to be one of the best and most intricate engineering materials created by nature and known to mankind [12].

Discussion on Issues and Solutions in Enterprise Information Construction from the Perspective of Engineering Economics Qigeqi Inner Mongolia University of Science and Technology, Baotou 014010, China iamyangxiaoming@163.com Keywords: engineering economics, enterprise information construction, solutions.
In the business operation, more frequent application of information technology is the key to all kinds of technical and system software and management.
Traditional IT information engineering cannot satisfy the needs of transforming operational mechanism and organizational structure of enterprises any more.
Under the new situations of the society, the relevant engineering department has to deeply realize the inseparable relationship between the long-term development of the enterprises and information construction, emancipate the mind, change traditional idea and promote the enterprise information construction actively.
As long as we can find the problems in enterprise’s information construction and come up with targeted solutions according to the actual situation, we can help the enterprises get strong support from the rear seat, and save a lot of manpower material resources as well.
