In EC - Bed Linen, the Appellate Body reversed the Panel's conclusion that "an interpretation of Article 2.2.2 under which sales not in the ordinary course of trade are excluded from the determination of the profit amount to be used in the calculation of a constructed normal value is permissible".(37) The Appellate Body emphasized that Article 2.2.2 refers to "actual amounts incurred and realized by other exporters and producers" and concluded that, in the light of this wording, in the calculation of weighted average all of the actual amounts have to be included, regardless of whether the underlying sales were made in the ordinary course of trade or not

在EC - Bed Linen案中，调查机构推翻了专家组所认为的"依据条款2.2.2的解释，排除在非正常贸易过程中适用确立计算正常价值的计算是可允许的"(37)调查机构强调，条款2.2.2是指"其他出口商和生产者所产生的和已实现的实际数量"，并且推断，依据这些措辞，在计算不得不包括的所有实际数量的加权平均值时，不管以下销售是否是在正常贸易过程中进行

First, the conception of wet compression is defined. A calculation method of moist air and wet gas thermodynamics properties is set up, which treat them as real gas and can give out the results of any water-air/gas ratio. Second, the thesis build the simulation model of water injection between compressor stages of a single shaft gas turbine, based on which the stable analysis is processed and the characteristics of key performance parameters are given out, such as the variation of air flow, pressure ratio, turbine inlet temperature with the water quantities. Results showed that enhancement of power output is outstanding.

Secondly, two physical models were constructed, which could model rough surface and describe the features of the earth surface, such as chine, neck, valley and hill, etc. According to difference method, the ""true"" volume of the physical models were measured, which was 13260cm3 and regarded as the analysis foundation of the precision of the volume that was calculate by DEM. The discrete dada of the models on a regular spacing of 1cm were collected by 3SPACE FASTRAK and the DEM was obtained by interpolating the discrete dada through GIS software. Based on the volume of the models calculated by DEM, different interpolating methods (IDW, Spline, Natural Neighbor, and Kriging) and variation of grid spacing of data were compared and their effects on precision of volume calculation were analyzed.
