1) The main function of communication tools used in site activities is mainly to deal with the data and transmit the data.
代写留学生论文The characteristics of modern tools of communication applicable to site activities include: A) various types, such as telephones, fax, intranet, extranet and so on, different types have different usage to satisfy different needs of site activities; B) widely and generally used; C) making the communication in the site activities much easier and more efficient to carry on; D); to transmit the flow of information more simply and more easily E) save money and materials.

2)  Projects are becoming increasingly complex and technology is advancing more and more quickly.
To select communication tools and links to a construction site, we should take the following factors into consideration:
A) capital costs, the expense to buy the tools and chose the way of links should within the budget; B) practicability, the tools and links should be practically used and can produce active effect for the construction site; C) efficiency, the application of the tools and links should actually improve the rate of the process of the construction; D) maneuverability, in reality, there are lots of workers on the construction site, and different people have different level of capability of operating the tools and links, therefore, the selection should base on the capability of the real situation, on both site condition and human force condition ; E) applicability, different conditions should be applied with different tools and links according to the real situation of the construction site, such as geographic condition or power supply condition.
1) The relationship and difference between reality, concept and object is that: concept is what we apply to things to objects in our awareness, in order to organize our mental life. Basically, humans use concepts to make sense of objects in our world, both the physical world as well those perceived mentally. Without concepts we cannot understand objects-what is a car? Reality is full of objects- we apply concepts to objects to shape our perception of reality. We may apply concepts to induce creativity and stipulate future concepts. Anything to which a concept applies is an object. Therefore, an object is an instance of a concept. The concept may be an object to another concept. To sum up, A) the reality is made up with objects, and we adopt concepts to define objects in order to recognize the reality; B) all concepts are objects however, not all objects are necessarily concepts. Only objects that apply as concepts to other objects can be regarded as concepts.

2) Object orientation technology is to collect all the data or data operation together, and mainly concern about the operation on data and the data-related interfaces.
Adopt object orientation technology can make construction works much easier to handle. Just take construction worker, the most essential and fundamental unit in the construction progress, as an example to explain the convenience of applying this technology. Reasonably, his behavior will involve various data, process, such as his typical behavior, like wall-building, brick-piling, and during he builds the wall, and the materials he will use will include bricks, concrete, reinforcing bars. According to the original programming procedure, those data and processes will be processed respectively, but now, we can cope with this problem by 本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
