Use of materials with an adapted thermal expansion coefficient.
Due to the iron-nickel materials the alloys ideally have similar thermal expansion characteristics.
Furthermore the deformation characteristics, which are facilitated by the thermoplastic materials, are to be examined.
In addition the authors would like to thank the Auerhammer, Aue firm for providing the materials.

Polymeric materials have their potential uses to inhibit aggregation of nanosilver particle [18, 19].
Thus, polymeric materials can also control the release of silver ions for reduction of cytotoxicity [21, 22].

With the transmission of logistics operation, Value accumulation in the enterprise internal happens, then finally takes products as aggregation of a series of operation of the enterprise, which forms and the final value in each operation in the performance of value aggregation. 4.1 Logistics Costing account of Wuhu Zhenghai Company Based on ABC Through the analysis of Logistics Costing account of Wuhu Zhenghai Company from raw materials purchase, production and sale, the paper try to specify how to account logistics cost based on ABC.
If the Monthly running time of production machine is 1675 hours and the utilization rate of facilities and management personnel are 80%, its operation cost and product cost are as Table 1, Table 2: Table 1 Operation cost material Units: Yuan resource operation Employees Per capita wage Electricity Office expenses Depreciations of fixed assets Order process 120 2000 15000 15000 240000 Pre-production 400 3000 32000 28000 500000 Production 500 4000 90000 32000 1000000 test 500 4000 80000 36000 1200000 packing 250 2000 60000 24000 400000 distribution 300 2000 50000 26000 540000 general management 300 3000 30000 35000 380000 Table 2 Product cost material car interior ceiling car pedal pad Output (piece) 15000 6000 direct material (Yuan/piece) 500 1000 Order process number (copy) 1000 5000 Pre-production (copy/piece) 1.5 2.5 Production (copy/piece) 4 5 Test (copy/piece) 3.5 5 Packing (copy/piece) 2 3 Distribution (hour/lot) 100 1 According to the above logistics procedure and dates

Table.1 Transformation-Flow-Value Theory[5] production transformation theory production flow theory value generation theory Concept From input to output conversion A material flow from the conversion, checking, moving and waiting for the composition Customer demand for the purpose, the process of creating the most value Main Principles Effective operation of production By eliminating non-value added activities to eliminate waste Maximize value Practical Application Task management Process management Value management Assistive Technology of Lean Construction.
For construction enterprises, zero inventory is to minimize the stock material and construction site materials in construction process as far as possible and to put materials into production immediately, avoiding secondary transfer fee[8] no longer.
Each process should execute strictly with the requirements proposed by next process, including personnel, materials, and machinery equipment.

This science is aimed to improve the work procedure, work techniques, work equipments and match them to mental and physical characteristics of human.
Target group and design criteria regarding to the mantioned materials and the study of domestic and foreign samples of dining table, it is necessary to be considered the following points in design as the premier criteria: using Iranians‘ eating style and custom; solving the ergnomic problems of sitting; using Islam instructions about the most correct ways on eating; making the form of dining table closer to Iranian forms; using the most modern and updated scientific methods in designing, such as modular design; easy pakaging; easy transportation; low weight and using an adequate material which is durable and easy to clean.
Finally the refined data was organized and classified based on the functional, ergonomic and aesthetic states called design criteria as follow: · Smart use of materials and forms in order to clean the table easily; · Contractibility in a small area when it is unused; · Considering the special ceremonies such as Ramadan and time of breaking a fast and dawning; · Changeability of its application from a familial friendly space to a formal party space; · Ease of individuals’ accessability to the things on the table; · Rotatability of table screen; · Assigning some special spaces to place anything (glass, saltshaker, etc.); · It helps to bring meals and take their containers to kitchen after finishing the food; · Being inspired from Iranian art; · Having the sense of comfort during eating; · Reminding the thanksgiving by the form and design of table or tablecloth; · Considering the ergonomic standards of sitting; · Adjustability of its height; · Low weight and easy portability;
The premier criteria, such as the use of Iraninans’ eating style and custom, the resolution of ergonomic sitting problems, the use of Islam instructions about the most correct methods of eating, making the form of furniture closer to Iranian forms, the use of most recent and updated scientific techniques in design like modular design, easy packaging, easy transportaion, low weight and the use of materials which are durable and easy to clean were gathered.
