结果表明：被调查农户人均退耕坡地0.205 hm2，退耕指数达79.21%；2003年479农户因退耕导致的粮食减产量人均74 kg，得到政府补贴人均171元；退耕补贴对贫困农户的影响程度较大，停止退耕补贴后存在反垦可能性。2003年被调查农户人均现金收入1492元，主要来源于外出打工、卖粮菜、退耕补贴、卖畜禽产品和做小生意等。未来几年，能获得稳定收入且报酬相对较高的行业是农民谋生的首选，有资金积累或一定技能的农户正在将生计转向高附加值农业或第三产业。

The decorates a wall general manager neat and tidy that rolls out this service is having his point of view, building materials market control person suit to take on most " whole journey inspect manages " part, first into what be stationed in the market business door wants to be handed in to the market keep gold character, no matter be data business, still decorate a company, cherish oneself quite the position in the market, so, on the service quality that is aimed at consumer, a bit not dare adulterate or laches; Second market control person the angle that can stand in fairness handles affairs, decorate a company to pledge check personnel makes an athlete already normally, ump member, in project quality supervise on have break evenhanded; And inspect grain company is inspect normally and cannot manage, because they are installed with the home,did not restrict between the company, once the project produces a problem, inspect grain company is solved feebly, adopt industrial and commercial bureau, pass the time in a leisurely way even assist wait for orgnaization processing.

推出这项服务的装饰城的总经理井然有着自己的观点，建材市场治理者最适合担当"全程监理"的角色，一则入驻市场的商户都要向市场交纳质保金，无论是材料商，还是装饰公司，都比较珍惜自己在市场中的位置，所以，在针对消费者的服务质量上，丝毫不敢搀假或懈怠；二则市场治理者能站在公平的角度办事，装修公司质检人员通常既做运动员，又当裁判员，在工程质量的监督上有失公允；而监理公司通常是监而无法理，因为他们同家装公司之间没有制约，一旦工程发生问题，监理公司无力解决，还要通过工商局、消协等机构处理。

The sample which has retrogressive phenomenon precipitates the secondary phase during re-ageing treatment subsequently, and the reprecipitation sequence is due to the grain size caused by severe plastic deformation. There is a critical grain size below which the reprecipitation sequence changes, the heterogeneous precipitation of phase at grain boundaries would suppress precipitation of metastable phases such as GP zones and η′ phase.

强变形导致回归后的合金在再时效处理时可再次沉淀析出第二相粒子，但析出相的析出顺序与强变形后合金的晶粒尺有相关，当晶粒细化到某一临界尺寸以下时，析出顺序发生改变，非均匀形核的平衡相可抑制GP区、η′亚稳相等前期粒子的析出。
