- Abstract : the conformal flat space - time solutions in electromagnetic and scalar theory are shown , and the indefiniteness of the plane - symmetric solutions and the method for defining a noncontinuous field by the intersection of multi - solutions are demonstrated
文摘:給出電磁場和標(biāo)量場在共形平直時(shí)空中的解,發(fā)現(xiàn)了平面對稱解的不確定性及由多重解的交集來定義一個(gè)非連續(xù)場的方法 - The one - loop vacuum polarization is calculated for untwisted and twisted scalar fields in a flat space - time with the topology s1 r3 . the effect of vacuum polarization upon photon propagation is considered . it is found that for the untwisted scalar field some photon modes acquire a positive topological mass , thus travelling at a subluminal speed ; but for the twisted scalar field some photon modes get an imaginary topological mass and travel at a superluminal speed
本文中我們首先計(jì)算了在拓?fù)浣Y(jié)構(gòu)為s ~ 1 r ~ 3的非minkowski時(shí)空中扭曲標(biāo)量場和非扭曲標(biāo)量場的真空極化，然后考慮了真空極化對光子傳播的影響，我們發(fā)現(xiàn)除了光子的極化方向和傳播方向都垂直于緊致化方向的情形之外，非扭曲標(biāo)量場的真空極化使所有其他的光子模式都獲得實(shí)的拓?fù)滟|(zhì)量從而導(dǎo)致這些光子以亞光速傳播；但是，扭曲標(biāo)量場的真空極化使光子獲得虛的拓?fù)滟|(zhì)量以致他們以超光速傳播。 - The equilibrium thermal radiation in a flat space - time or a curved space - time behaves like planck black spectrum represented with coordinate quantities . we regard the fact that the radiation from a thermal equilibrium system shows planck black spectrum as a basic physics law , from which it is demonstrated that the transitivity of clock rate synchronization is equivalent to the zeroth law of thermodynamics . the condition of clock rate synchronization is weaker than that constructing simultaneity surfaces . in the space - time satisfying the condition of clock rate synchronization , the zeroth law of thermodynamics is valid . on the other hand , in the space - time where the zeroth law is valid , one can define an identical clock rate
平直或彎曲時(shí)空中的平衡熱輻射，表現(xiàn)出用坐標(biāo)量表示的普朗克黑體譜.把熱平衡系統(tǒng)的輻射具有普朗克黑體譜作為一條基本的物理規(guī)律，以此為基礎(chǔ)，論證鐘速同步的傳遞性等價(jià)于熱力學(xué)第零定律.鐘速同步的條件比建立同時(shí)面的條件要弱.滿足這一條件的時(shí)空，熱力學(xué)第零定律在其中成立.第零定律成立的時(shí)空，一定可以定義統(tǒng)一的鐘速 - It's difficult to find flat space-time in a sentence. 用flat space-time造句挺難的
