本发明中，所谓的“变界流体机构”是指滚动转子膨胀机构以外的，流体进入区内的运动件的表面和流体流出区内的运动件的表面不同的容积型流体机构，这种流体机构包括但不限于滚动转子膨胀机构以外的包括圆形气缸、隔离体和缸内旋转体，且由所述圆形气缸、所述隔离体和所述缸内旋转体三者相互配合形成容积变化的机构，例如：两角转子流体机构、贯穿滑片流体机构等。
换句话说，所谓的“变界流体机构”是指一切除滚动转子机构以外的流体进入区内的运动件的表面和流体流出区内的运动件的表面不同的容积型流体机构，也就是说，所谓的“变界流体机构”是由旋转运动件形成容积变化的一切容积型流体机构，例如，滑片泵、滑片式机构(例如，滑片式压缩机或滑片式膨胀机)、偏心转子机构(例如，偏心转子压缩机或偏心转子膨胀机)、液环式机构(例如，液环式压缩机或液环式膨胀机)、罗茨式机构(例如，罗茨式压缩机或罗茨式膨胀机)、螺杆式机构(例如，螺杆式压缩机或螺杆式膨胀机)、旋转活塞式机构(例如，旋转活塞式压缩机或旋转活塞式膨胀机)、摆动转子式机构(例如，摆动转子式压缩机或摆动转子式膨胀机)、单工作腔滑片式机构(例如，单工作腔滑片式压缩机或单工作腔滑片式膨胀机)、双工作腔滑片式机构(例如，双工作腔滑片式压缩机或双工作腔滑片式膨胀机)、贯穿滑片式机构(例如，贯穿滑片式压缩机或贯穿滑片式膨胀机)、齿轮流体机构(例如，齿轮压缩机或齿轮膨胀机)和转缸滚动活塞机构(例如，转缸滚动活塞压缩机或转缸滚动活塞膨胀机)等。所述变界流体机构可选择性地选择包括气缸、隔离体和缸内旋转体，且由所述气缸、所述隔离体和所述缸内旋转体三者相互配合形成容积变化的机构。
本发明中，所谓的变界流体机构可以这样理解：例如气缸活塞机构、它的流体流入区内的运动件是活塞，其表面是活塞顶面，它的流体流出区内的运动件也是活塞，其表面也是活塞顶面，所以这样的机构不属于所述变界流体机构，叶轮压气机属于变界速度型流体机构，两角转子流体机构、三角转子流体机构和贯穿滑片流体机构的流体进入区内的运动件的表面和流体流出区内的运动件的表面不同，因此这类流体机构属于变界流体机构。
本发明中，所述圆形气缸是指在与所述缸内旋转体的旋转轴线相垂直的平面内气缸的内侧轮廓线为圆形的任意形状的腔体，例如：圆柱形气缸、圆锥形气缸、圆台形气缸和球面圆形气缸。
本发明中，所谓的“第一级”是指按流体的流动方向处于最上游的一级。
本发明中，所谓的“最末一级”是指按流体的流动方向处于最下游的一级。
本发明中，所述工质控制阀包括逆止阀(单向阀)。
本发明中，所述工质控制阀a和所述工质控制阀b都是控制阀，名称不同只是为了区别而加以定义的。
本发明中，所谓的“A与B联动设置”是指A与B相互有驱动作用的设置方式，包括共轴设置方式。
本发明中，所述速度型压气机包括叶轮式压气机。
本发明中，所述速度型做功机构包括叶轮式做功机构。
本发明中，某个数值A以上和某个数值A以下均包括本数A。
本发明人根据热力学的基本原理以及对宇宙现象的观察认为：在没有外部因素影响的前提下，热不可能百分之百的转换成其它任何形式的能量或物质。传统热力学第二定律中只阐述了在没有外部因素影响的前提下，热不能百分之百的转换成功，这一定律是正确的，但又是片面的。可以用通俗的语言将热定义为能量的最低形式，或者简称为这是宇宙的垃圾。经分析，本发明人还认为：任何生物(动物、植物、微生物、病毒和细菌)的生长过程都是放热的。经分析，本发明人还认为：任何一个过程或任何一个循环(不局限于热力学过程，例如化学反应过程、生物化学反应过程、光化学反应过程、生物生长过程、植物生长过程都包括在内)其最大做功能力守恒，本发明人认为没有光合作用的植物生长过程是不能提高其做功能力的，也就是说，豆芽的做功能力是不可能高于豆子的做功能力加上其吸收的养分的做功能力之和；之所以一棵树木的做功能力要大于树苗的做功能力，是因为阳光以光合作用的形式参与了由树苗到树木的生长过程。
本发明人认为：热机工作的基本逻辑是收敛-受热-发散。所谓收敛是工质的密度的增加过程，例如冷凝、压缩均属收敛过程，在同样的压力下，温度低的工质收敛程度大；所谓受热就是工质的吸热过程；所谓发散是指工质的密度降低的过程，例如膨胀或喷射。任何一个发散过程都会形成做功能力的降低，例如，气态的空气的做功能力要远远低于液态空气的做功能力；甲醇加水加中等温度的热生成一氧化碳和氢气，虽然所生成的一氧化碳和氢气的燃烧热大于甲醇的燃烧热20％左右，但其做功能力大于甲醇的做功能力的比例则微乎其微，其原因在于这一过程虽然吸了20％左右的热，但是生成物一氧化碳和氢气的发散程度远远大于甲醇。因此，利用温度不高的热参加化学反应是没有办法有效提高生成物的做功能力的。
距离增加是熵增加的过程，冷热源之间的距离也影响效率，距离小效率高，距离大效率低。
本发明中，应根据热能与动力领域的公知技术，在必要的地方设置必要的部件、单元或系统等。
本发明的有益效果如下:
本发明所述多级流体机构控制简单、效率高。
