141 typical magnetic storms of the sudden commencement (SC) type, of which 45, 42 and 54 have strong, weak and no main phase respectively, have been selected from the magnetographs obtained at Zo-Se observatory during 1936~1962. Using data of solar flares and radio bursts of type 1V, the flares corresponding to the storms have been identified. The statistical properties of the three types of storms and their corresponding flares are investigated by statistical mathod. The charecteristics of corpuscular streams emitted by flares are evaluated. By means of correlation analysis, the relations between storm's charecteristics and the charecteristics of flares as well of corpuscular streams are investigated. The main conclusions are as follows; 1. The flares producing the storms with strong main phase are stronger. They concentrate mainly near the central meridian of the solar disk; while the flares producing the storms with weak or no main phase are weaker. The distribution on the solar disk of the former have strong east-west asymmetry, while that of the latter are rather uniform. 2. The formation of the storm's main phase is closely related to the velocity of the corpuscular stream, while the relation with the density of stream, is poor. On the average, the density at the front of streams producing SC storms is 10~40 proton/cm~3. 3. The emitting angle of the corpuscular streams producing SC storms is about 120°±(20°~30°). The lower limit of the total kinetical energy of streams is 10~(27)~10~(28)erg. 4. a_(p max) and K_(p max)—maximum values of α_p and K_p during storms- are closely correlated with the velocity v of streams, while the correlation between the maximum amplitude ΔH_(max) of storm's main phase and v is very poor. 5. The geomagnetic latitude of the Sun, i. e that of subsolar point, affects not only the type, but also the intensity of storms, and it appears that the effect on intensity is more inportent.

根据1936—1962年佘山地磁台磁照图,选出141个典型的急始型(SC)磁暴,其中强主相、弱主相和无主相磁暴分别为45个、42个、54个。利用耀斑和1V型射电暴等资料证认出对应的耀斑。用统计方法研究了三类磁暴及对应耀斑的统计特性。估计了耀斑抛射的微粒流的特性。用相关分析研究了磁暴特性同耀斑和微粒流特性的关系。本文得到的主要结论是: 1.产生强主相SC磁暴的耀斑较强,主要集中在日面中心经圈附近;产生弱主相和无主相SC磁暴的耀斑较弱,前者沿日面的分布有明显的东西不对称性,后者沿日面的分布比较均匀。 2.磁暴主相的形成同微粒流的速度关系密切,但同微粒流密度的关系不大。平均而言,SC磁暴对应微粒流前锋处的密度是10—40质子/厘米~3。 3.SC磁暴对应微粒流的抛射角约为120°±(20°—30°),总动能的下限为10~(27)—10~(28)尔格。 4.磁暴时ap和Kp的极大值ap_(max)和Kp_(max)同微粒流速度v关系密切,而磁暴主相极大振幅ΔH_(max)同v的关系却很不密切。 5.太阳的磁赤纬(卽日下点的地磁纬度)对磁暴的强弱和类型都有影响,可能主要影响强弱。

The present paper starts from the Bethe-Salpeter equation for the bound states of a fermion and anti-fermion pair. Assuming that the interaction between the straton and anti-straton can be represented approximately by an instantaneous interaction in the center of mass system, we obtain the following main conclusions: (1) the solution of the Bethe-Salpeter equation may be carried out in ordinary three dimensional space and the numbers of components of the wave functions for the pseudo-scalar and vector...

The present paper starts from the Bethe-Salpeter equation for the bound states of a fermion and anti-fermion pair. Assuming that the interaction between the straton and anti-straton can be represented approximately by an instantaneous interaction in the center of mass system, we obtain the following main conclusions: (1) the solution of the Bethe-Salpeter equation may be carried out in ordinary three dimensional space and the numbers of components of the wave functions for the pseudo-scalar and vector mesons reduce respectively from 4 and 8 to 2 and 4; (2) If the interaction is spherically symmetrical in space and its spinor structure is of the diagonal coupling type, then it is seen from the equation for the pseudo-scalar mesons that the meson mass appears as a quadratic eigen value in the equation, without leading to the negative energy excitation usually encountered in the fourdimensional equation; (3) The structure wave function obtained in the instantaneous interaction may be used to study both the mass spectra of the bound states, and the processes involving only the center of mass system.

本文从一对正反费米子结合成束缚态的Bethe-Salpeter方程(以下简称B-S方程)出发,假定正反层子间相互作用可以近似地用质心系瞬时相互作用描写,得到的主要结论如下:(1)B_S方程的求解可归结为在质心系三维空间内进行。描写赝标介子和矢量介子的波函数独立旋量分量的个数分别由4个和8个减少为2个和4个;(2)如果相互作用是空间球对称的,其旋量结构是对角耦合,从赝标介子方程中可以直接看到,束缚态质量作为本征值在方程中是以平方形式出现,同时又可避免四维方程中负激发的困难;(3)在瞬时相互作用近似下给出的结构波函数,可以用来研究束缚态的质量谱和只涉及质心系的过程。
