3. 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:給出電磁場和標量場在共形平直時空中的解,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非連續(xù)場的方法
4. 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
   本文中我們首先計算了在拓撲結構為s ~ 1 r ~ 3的非minkowski時空中扭曲標量場和非扭曲標量場的真空極化，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，非扭曲標量場的真空極化使所有其他的光子模式都獲得實的拓撲質量從而導致這些光子以亞光速傳播；但是，扭曲標量場的真空極化使光子獲得虛的拓撲質量以致他們以超光速傳播。
5. 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
   平直或彎曲時空中的平衡熱輻射，表現(xiàn)出用坐標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，論證鐘速同步的傳遞性等價于熱力學第零定律.鐘速同步的條件比建立同時面的條件要弱.滿足這一條件的時空，熱力學第零定律在其中成立.第零定律成立的時空，一定可以定義統(tǒng)一的鐘速
6. It's difficult to find flat space in a sentence. 用flat space造句挺難的
