The merging layer adopted heteropic gradient material, and which was compounded with two or more materials.
But they all didn't consider mutual effect among Ingredient materials, and the results were inaccurate.
On the other hand, low-melting welding powder is a kind of composite material and coefficients of heat expansion of various materials in welding powder are inconsistent.

Analysis of wetland value assessment methods Han Mei1,a Wang Xiaoyan1,b 1College of Population, Resources and Environment, Shandong Normal University, Jinan 250014, China a hanmei568568@126.com,b wangxiaoyan106@163.com Keywords: wetland; wetland functions; value; assessment methods Abstract: Wetland science research has earned great attentions and wetland assessment is an important part of wetland science characterized by complex context and various assessment methods.
Ecosystem service functions of wetland are divided into three types in this paper, material production function, environmental function and social and cultural function, including biology production, hydrological regulation, erosion control, water and atmosphere purification, biodiversity maintenance, providing habitat, leisure travel, educational research and so on.

In the field of material science and structural engingeering, the size differs between laboratory specimen and pratical constructions is inevitable.
Interests in the size effect is very old, in fact older than the mechanics of materials itself.

Materials and Methods Shipbuilding Production Process.
Large waste can be found by carefully observing team members, equipment, materials and processes in the actual production process.
So that the transportation process (parts, raw materials and people) is more than what is needed should be.
For example: the process of processing materials between a process to the next process must be contiguous.
