Study on the Performance of Orange Oil Cleanser Zhiqiang Li1, a, Mei Li1, b, Shihan Wang1, c ,Jie Jiang1,d , Mubing Wang1,e , jinhuang Huang1,f 1College of Science, Civil Aviation University of China, Tianjin City, 300300 China alizq57@163.com,bmli57@163.com,C176499780@qq.com,d328668475@qq.com e1198840971@qq.com,f1311879297@qq.com Keywords: Cleanser, Orange oil, Surfactants, Uniform experimental design, Biodegradation.
The percentage of material biodegradability is DT (%): DT= σ (CO2)/ThCO2 Formulation design Selecting uniform design, three levels of factor seven.
Therefore, the percentage of material biodegradability is DT =(113.58/120.168)×100%=94.52%.It is obvious that the percentage of material biodegradability is very high.

For this vibrating simulation, the geometric profile of a welded bellow, as shown in Fig. 1(c), could be interactive by various parameters through ANSYS toolboxes, and its material properties was predefined as AM 350 stainless.
There are five important factors for welding consideration: (i) welded material properties including thermal conductance, material structure and composition as well as thickness relative to welded area, and welded distance relative to the melted amount; (ii) argon flow rate and purity (notated by percentage); (iii) welded parameters containing operational current (A), duty cycle for a pulsed period (%), pulsed frequency (Hz), and welded speed (radius/sec) and microplasma torch distance (mm) on welded areas of a convolution; (iv) level of surface conditions on the welded area and cleaning environment; (v) jig and fixture design including the pin and nozzle shape for the microplasma jet [5].

To estimate the instantaneous forces the mass of the oscillating wing was obtained for the following dimensions: a 0.6 m wing span l and a 2800 kg/m3 material density (aluminium) were chosen and the respective wing mass m of 1.38 kg (13.52 N).
Hence, a flapping wing should try to emulate this design by using ultra light and hard materials.

� Corresponding.author : sbjung@skku.ac.kr Title of Publication (to be inserted by the publisher) Experimental Procedure The material used was 6061-T6 Al alloy which had 140 mm in length, 70 mm in width and 4 mm in thickness.
No precipitates were observed at the stir zone due to the resolution in the Journal Title and Volume Number (to be inserted by the publisher) Al matrix.

Then the material object index datum of these natural assets and its change would be collected.
Finally through valuation, material object index datum was converted into monetary data.
For pricing methods in resource and environment are so complex, and no uniform quantitative criteria, material object indicators and value indicators should be paid equal attention to.
