作者：倪向善陈润生 Institute of Biophysics Academia Sinica Beijing Institute of Biophysics Academia Sinica Beijing model of protein synthesis in an oosperm was put forward by Chen Runsheng where all the molecules of aminoacid and protein were considered as spherical ones. In this paper the case where they are all ellipsoids of revolution is considered but the rotation of the molecules during diffusion is not taken into account. Also the hypothesis of dilute solution is used. Since the cleavage of the first time may take place at any stage of evolution and uncertainly do at the time when the steady state is reached solving directly the dynamic partial differential equations will contribute to the acquirement of some fundamental ideas of the whole process of protein synthesis in an oosperm.

The fast rotation of sunspot group 5395 ( first, it exhibited inverse clockwise rotation, then clockwise rotation, the rotative angle was the lagrest 1-2 days before proton flare.) the stronger emission of SVC and the spectral maximun (near 8800MHz) of both the SVC and peak fluxes of the bursts et al are close correlated with occurrence of proton flares. Flares often generated in the regions of emerging or disappearing of new magnetic flux with opposite polarity, of the faster and more complex variation of the gradient and configuration of magnetic field, and of the neck and tail of magnetic gulf.

With the rapid development of observational technology, the observable distance has extended to 1010 light years, far away from the earth. In the observable space, as many as 109 galaxies have been discerned. The structure and morphology of the galaxies differ greatly from one another. Nevertheless, many of their geometric and dynamic parameters and a few of the relations among these parameters have been determined by astronomical observations. The important parameters and some of their relations are as follows. （ⅰ） There is red shift in the spectrum of every one of the galaxies observed. The relation between the red shift Z and the distance R of a galaxy,
