When the temperature to gas pipelines , temperature packets of material expansion , the pressure rise , inflation pressures are rising corrugated box , corrugated promote the expansion thrust to overcome the spring - loaded pole resistance , the ball - type valve opened for big change ; when the gas pipeline to reduce the temperature , temperature of the material swelling up , the pressure lowered inflation corrugated box pressure also reduced , spring - loaded pole compressed corrugated of resistance to thrust , spherical valves open for smaller ; this constant push and pull adjustment for the balance , as long as refrigeration cycle continue 当回气管道温度升高，感温包内的物质膨胀，压力升高，膨胀波纹箱内压力也升高，波纹腔膨胀推动推力杆克服弹簧阻力，球型阀开度变大；当回气管道温度减低，感温包内的物质膨胀，压力降低，膨胀波纹箱内压力也降低，弹簧阻力推动推力杆压缩波纹腔，球型阀开度变小；如此不断的进行推拉调整平衡，只要制冷循环继续下去。
Behind us is nha trang no 88 - 90 , a simple but marvellous little place for vietnamese noodles and other snacks . william pops in to pick up a stack of free postcards . we turn the corner into lyndhurst terrace and we are nearing the end of our tour , both literally and metaphorically , for we are about equidistant from the illustrious entertainment area of lan kwai fong , and the newer soho neighbourhood , its narrow streets lined with funky restaurants and bars 看似简单的甜食，用鸡蛋面粉糖拌匀造成蛋浆，倒进一排排小半球型金属电烤板中烘香，然后把整块小球状蛋饼从烤板挑出，趁热用手把一颗颗的鸡蛋仔翻出，入口热烘香脆，老幼咸宜，此品魅力没法挡，很多人都顾不了仪态，边走边吃，趁热入口毕竟效果最佳。
Because expansion valves are high precision processing components , factory in its internal adjustment of the body parts are processed in a state of complete thermostatic , the temperature of the gas filling kits are demanding more consistent not detect leaks , in the completion of the expansion valve assembly also undergo strict testing and fatigue resistance aging sampling , the construction expansion valves : 1 : indeed temperature temperature kits ; 2 : temperature gas or liquid filled with the expansion corrugated ; 3 : spherical valve seat ; 4 spherical valves ; 5 : spring ; 6 : overheating degrees adjustment screw spacer and screw ; 7 : internal and external ( h - type ) sealed pieces ; 8 : thrust poles and corrugated of spacer ; 9 : fati ; 10 : capillary , and so on 因为膨胀阀是属于超高精密加工的零件，在工厂对其内部调整机构零件的加工都在恒温状态下完成，其中的感温包的气体充填更是要求严格一致不允许一丝泄漏，在完成装配的膨胀阀还要经过严格的测试和耐疲劳老化抽检，膨胀阀的构造： 1 ：感知温度的感温包； 2 ：感温气体或者液体充填膨胀波纹腔； 3 ：球型阀座； 4球型阀； 5 ：弹簧； 6 ：过热度调整螺丝垫片和螺丝； 7 ：内部和外部（ h型）密封件； 8 ：推力杆和波纹腔垫片； 9 ：阀体； 10 ：毛细管等等。
This dissertation established a novel distributed spaceborne sar simulation system based on the high level architecture ( hla ) . this dissertation developed a mathematical model of instantaneous sphere earth model and instantaneous circle orbit model for the geometry system between the satellite platform and the targets on earth based on the satellite platform ’ s orbit features and sar system ’ s operational characteristics , unlike the traditional sphere earth model and circle orbit model 本文从建立精确的、易于仿真的星地几何关系入手,舍弃了传统的星载sar研究中的球型地球模型和圆形轨道模型,根据星载sar的轨道特点和sar的工作特点,对局部球型地球模型进行改进,建立了在瞬时球型地球模型和瞬时圆形轨道模型下的星载sar仿真。
