In the present invention, so-called " clockwise direction ", so-called " ten two directions ", so-called " ten one point " and so-called " 7 points " are the definition based on clock.
In the present invention, so-called " volume type become boundary hydraulic mechanism " refers to that surface that all fluids enter the movement parts in district and fluid flow out the different volume type hydraulic mechanism in the surface of the movement parts in district, that is, so-called " volume type becomes boundary's hydraulic mechanism " is all the volume type hydraulic mechanism being formed volume-variation by rotating motion part, such as, sliding vane pump, sliding vane mechanism (such as, sliding-vane compressor or sliding vane type expander), eccentric rotor mechanism (such as, eccentric rotor compressor or eccentric rotor decompressor), liquid-ring mechanism (such as, liquid-piston compressor or liquid-ring decompressor), roots-type mechanism (such as, Roots Compressor or roots-type decompressor), screw-type mechanism (such as, screw compressor or screw type expansion machine), rotary-piston type mechanism (such as, rolling piston compressor or rotary-piston type decompressor), rolling-piston-type mechanism (such as, rolling piston compressor or rolling-piston-type decompressor), swing-rotor type mechanism (such as, swinging rotor type compressor or swing-rotor type decompressor), single active chamber sliding vane mechanism (such as, single active chamber sliding-vane compressor or single active chamber sliding vane type expander), Double working chamber slide sheet type mechanism (such as, Dual-cavity sliding vane type compressor or Double working chamber slide sheet type decompressor), penetration slipping sheet formula mechanism (such as, penetration slipping sheet formula compressor or penetration slipping sheet formula decompressor), gear fluids mechanism (such as, gear compressor or gear decompressor) and Zhuan Gang rolling piston mechanism is (such as, turn cylinder rolling piston compressor or turn cylinder rolling piston expander) etc.Described volume type becomes boundary's hydraulic mechanism and optionally selects to comprise cylinder, slider and cylinder inner rotary body, and complements each other to form the mechanism of volume-variation by described cylinder, described slider and described cylinder inner rotary body three.
The present inventor thinks, celestial body mutually moves and certainly leads to gravitational interaction, gravitational interaction certainly leads to flow of matter and/or object deformation, because flow of matter and object deformation are irreversible process, namely the process producing heat is, therefore the flow of matter under gravity field effect and object deformation certainly lead to heat, the heat that this form produces must consume the kinetic energy of celestial body, As time goes on, through very long process, it cognition loses kinetic energy gradually, merging (or mutually engulfing) is mutually known from experience in final sky, final universe forms a particle, the temperature and pressure of this particle all can acutely rise, thus form violent blast (also can cause chemical reaction and nuclear reaction because temperature and pressure acutely rises), blast forms celestial bodies motion state again, even if celestial body has kinetic energy, mutual relative movement and interaction is again formed between celestial body, enter next circulation.Therefore can think that the existence in universe is a thermodynamic cyclic process with development in fact.The essence of this process can be summarised as simple, understandablely " you invite me, and I just necessarily engulfs you ", and as can be seen here, its final final result of main body that there is alternating action is exactly mutually engulf, mutually merge.
As everyone knows, in economics, all authorized the Nobel Prize to the research of information asymmetry and information symmetrical, visible both parties have Determines transaction success or failure, the fairness of transaction and the profit of transaction of information.The essence of transaction is information trading in fact.For the present inventor thinks, patent has information zero symmetry properties, and namely the true value of both parties to patent is all known little about it.Patent information zero symmetric properties, if do not cracked, operation is difficult to realize.Information zero symmetry properties of patent determines science and the complexity of patent operation.In general goods transaction, information asymmetry is conducive to promoting transaction, improves profit.And for patent, then completely different, patent needs technical solution problem, the value of patent is known very soon in patent exploitation, so patent must be out-and-out, information zero is symmetrical and information asymmetry is inevitable all can seriously hinder patent operation, solution patent information zero AXIALLY SYMMETRIC PROBLEMS, makes both parties' information symmetrical on high level be the basic work of patent operation enterprise.
The present inventor thinks according to thermodynamic (al) basic principle and on the observation of universe phenomenon: under the prerequisite affected not having external factor, and heat absolutely can not convert other any type of energy or material to.Only set forth in conventional heat second law under the prerequisite not having external factor to affect, heat can not absolutely be changed successfully, and this law is correct, but is unilateral.With popular language, heat can be defined as the minimum form of energy, or be the rubbish in universe referred to as this.By analysis, the present inventor also thinks: the growing process of any biology (animal, plant, microorganism, virus and bacterium) is all heat release.By analysis, the present inventor also thinks: any one process or any one circulation (are not limited to thermodynamic process, such as chemical reaction process, biochemical reaction process, photochemical reaction process, biological growth process, growing process are all included) its maximum acting ability conservation, the present inventor thinks does not have photosynthetic growing process can not improve its acting ability, that is, the acting ability of bean sprouts is the acting ability sum that impossible add its nutrient absorbed higher than the acting ability of bean or pea; Why the acting ability of one tree wood is greater than the acting ability of sapling, is because sunlight take part in by the growing process of sapling to trees with photosynthetic form.
The present inventor thinks: the basic logic of heat engine work restrain-be heated-is dispersed.So-called convergence is the increase process of the density of working medium, and such as condensation, compression all belong to convergence process, and under same pressure, the working medium degree of convergence that temperature is low is large; It is exactly the endothermic process of working medium that what is called is heated; What is called disperses the process referring to that the density of working medium reduces, such as, expand or spray.Any one disperses the reduction that process all can form acting ability, and such as, the acting ability of the air of gaseous state will well below the acting ability of liquid air; The heat that methanol plus water adds moderate temperature generates carbon monoxide and hydrogen, although the carbon monoxide generated and the ignition heat of hydrogen are greater than the ignition heat about 20% of methyl alcohol, but the ratio that its acting ability is greater than the acting ability of methyl alcohol is then very little, although its reason is that this process has inhaled the heat of about 20%, the degree of divergence of resultant carbon monoxide and hydrogen is far longer than methyl alcohol.Therefore, utilizing the not high physochlaina infudibularis of temperature to add chemical reaction is the acting ability having no idea effectively to improve resultant.
The present inventor thinks: it is the process that entropy increases that distance increases, and the distance between cold & heat source also affects efficiency, high apart from little efficiency, low apart from large efficiency.
In the present invention, according to the known technology of heat energy and dynamic field, necessary parts, unit or system etc. should be set in the place of necessity.
Beneficial effect of the present invention is as follows: oriented suspending bearing disclosed in the present invention have structure simple, significantly can reduce the advantages such as the power consumption that produces due to centrifugal force, and make the mechanism of application suspension bearing of the present invention have better service behaviour.
