内容摘要：在建设工程发包中，业主代扣营业税金及附加的情况十分普遍，总包单位如何对分包工程代扣税金进行正确的核算，《企业会计制度》、《施工企业会计核算办法》以及 2006年颁布的《企业会计准则第15号——建造合同》中均未对分包工程的会计核算作出明确的规定，本文就是真对这一情况，就业主代扣税金的分包工程税务处理及会计核算方法进行了详细的阐述。

The VSCF DFIG wind power generation is transient response proceeding, which is influenced by operation characteristics of generator before and after grid connected. A novel S-Function is adopted to describe the mathematic model of DFIG based on state equation. A complete simulation model of VSCF DFIG wind power generation system based on MATLAB/Simulink and SimPowerSystems is established, which can be used to not only simulate subsystems of no-load operation and generation operation, as well as can be used to but also accurate control parameters of DFIG in simulation. The simulation model have excellent transportability, and can be used DFIG of different power rated if only design relevant controller.

变速恒频双馈电机风力发电是一个受并网前后发电机运行状况影响的暂态过程，利用MATLAB的S-Function编写DFIG的仿真程序，然后结合Simulink和SimPowerSystems工具箱，开发了基于S-Function的空载运行和发电运行的变速恒频双馈电机风力发电子系统模型，在仿真过程中可对双馈电机进行精确控制，然后对其进行了系统整合，本文开发的模型具有可移植性，只要再设计相应的控制器，就可应用于不同功率等级的双馈电机风力发电系统。

It was typically indirect effect that the following variations induced in the progenies of endosperms implanted by heavy ion beams were discovered. 1 In comparison with control, there were very high differences in biological trait, anti-oxidation enzyme activity, MDA content and protein content, chromosome aberration rate and micro-nucleus rate in M1 generation. 2 Shorter stem variants and purple stem mutants were analyzed by RAPD and AFLP. The analytic results showed that the sequences of their DNA were changed, so those variations were not physiological damage only. And there were differences among M2 generation plants of the same sort of variants or mutants, it was indicated that M2 generation may be in disjunction.
