On the basis of the Straton Model, and through the application of the harmonic oscillator potential, Coulomb potential and square-well potential to the Bethe-Salpeter equation, the structure of J/ψ particles is discussed in this paper. The mass spectrum obtained is in good agreement with the experiments. It looks that the mass splitting of J/ψ particles may be mainly accounted for as radial excitation.

At present, there are two primary views of the planet formation in our country: the first one considers planets formed from the small star gathering, the other considers planets formed from nebular substance gathered into raw planets through potential well. In this paper, we consider that the law of conservation of angular momentum is an important key for understanding the origin of the solar system and the manner of formation of planets or moons. Any theory must be faced with its verification. The total sum of angular momentum (Ac) for the revolution of nebular substance of certain planet regions around the sun subtract the. angular momentum (Ap-) for the planet orbit of today in those regions ought to be equal to angular momentum (Ar) of rotation for the planet of these regions, i.e. Ac-Ap = AA = Ar. But the computation has been obtained as follows: Ac-Ap =△A > Ar. Thus it proves planets formed through the annular nebula. The positions of internal and external boundaries of the annular nebula, the width of the annular nebula are computed. By which some new views are suggested.Some good data are supplied for the theoretical study of planet formation.

行星形成的方式,目前主要有两种见解:一种认为,行星是星子集聚而成,另一种认为,行星是由星云物质经过势井聚集为原行星而形成。笔者认为,角动量守恒定律,是认识太阳系起源和行星、卫星形成方式的重要钥匙。某一行星区的星云物质绕太阳转动的角动量总和(A_c)减去该区今日行星轨道角动量(A_p)应当等于该区行星自转角动量(A_r),即A_c-A_p=△A=A_r。但计算结果,A_c-A_p=△A>A_r。这就证明,行星是经过星云环形成的。文中计算了星云环内外边界的位置,即星云环的宽度,并提出一些新的看法,可能为行星形成方式的研究提供一些有益的线索。

In the first placet from the classical point of view, we take two potential models, namely, the double-well-potential model and cosine-potential model, to study the classical motion of particles in channel and, at the same time, the capture state and non capture state of particles in channel are discussed. Moreover, from quantum aspect, we study the propagation of wave function of particles in channel.
