光在引力场中传播时,频率将会发生改变,但通常考虑光的引力红移时,却没有涉及到光子的静质量.从"重"电磁波的Proca方程出发,研究了线性引力波场中Proca光的频移.数值计算结果表明:若考虑光子的静质量,其频移效应将产生一个微小的修正(附加频移),但在目前的实验条件下不会产生可以观测的效应.  相似文献

提出了低于光速的正物质(三维空间物质)具有正引力场能,外在表现为放热(或有热辐射),有正引力场(有向心力、正引力).等于光速的0(零)物质有0(零)引力场,也论证了超光速的虚物质(四维空间物质、暗物质)具有负引力场能,外在表现为吸热,具有反引力场(排斥力),超光速的虚物质(四维空间物质、暗物质)因为具有负引力场能,结果导致了宇称不对称现象.论证了电子和正电子的物质湮灭转化为超光速的虚物质(虚光子),并推导出了虚光子γ的质量为5.006×10-41 g.也推导出了超光速虚光子γ的薛定谔方程,并且论证了高能量场虚光子γ的能量E2是有8个能量相位(太极八卦相位)的.  相似文献

用强场激光探测轴子实验中的光子静质量效应   总被引:1,自引:0,他引:1  
在重电磁场理论背景下,探讨了用激光通过强磁场探测轴子的高精度实验中光子静质量效应的大小和影响,并与调制扭秤实验给出的光子静质量限作比较.结果表明:此类实验中光子静质量效应对轴子质量限的影响很小;实验给出可能的光子静质量限mr<1×10-3eV,精度远小于调制扭秤实验给出的光子静质量限精度,扭秤实验仍是目前检测光子静质量的有效手段.  相似文献

按照黎曼几何与广义相对论,粒子在引力场中自由降落时沿短程线运动。广义相对论采用弧长s作为变分参数建立短程线方程,得到粒子在球对称引力场的运动轨道。在太阳系弱引力场中做牛顿近似时,用到了弧长的近似条件ds=cdt。然而在引力场中这个近似条件是不合理的,它不但表示粒子静止,而且是静止在没有质量的自由空间中。本文证明,对于球对称引力场的施瓦西度规做正确的近似后,物体只能做抛物线运动(非周期运动),不可能做椭圆和双曲线轨道运动。为了避免近似计算的不确定性,本文进一步采用任意变分参数建立短程线方程,严格证明按照广义相对论,物体在太阳系弱引力场中只能做抛物线轨道运动,不可能做椭圆轨道运动。因此对于太阳系的行星轨道周期运动,广义相对论是无效的。本文还讨论了光在太阳引力场中的产生偏折的运动方程及其近似解。指出该解会导致自相矛盾的结果,因此它不是广义相对论运动方程的真正的解。原因在于爱因斯坦引力场方程是非线性的,其解不满足线性叠加原理,广义相对论关于光在太阳引力场中的偏折的计算与实际观察一致纯属歪打正着。本文同时证明,广义相对论对雷达波时间延迟实验的计算则是错误的,误差高达14.9%。因此广义相对论并没有得到实验的证实。爱因斯坦弯曲时空引力理论不可能成立,现代物理学的引力理论必须重建。  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.  相似文献

Wuthering Heights, Emily Bronte's only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.  相似文献

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3~4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰~ -7.8‰, PDB) and matrix dolomites (-6.6‰~ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084~0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078~0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

Quality traits in wheat (Triticum aestirum L.) were studied by quantitative trait locus (QTL) analysis in a recombinant inbred line (RIL) population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross (ChSh). Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献
