INTRODUCTION The two-step photoionization process may be used in realization of isotope separation for most elements. But the research effort on this topic has not been sufficient. To our knowledge Karlov's papers are the only literature for laser separation of isotopes of Sm published up to now. Thus a study of isotope separation of Sm will be very valuable.

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,

One of the features of the rare earth elements is that their 4f electronic shells are unfilled, and their physio-chemical properties also depend on this in some degree. One may expect that the binding energy chemical shifts of 3d and 4d electrons of M （rare earth metal ion） in （TTA）4 MQH are related to the 4f electrons. On the other hand the binding energy data can also provide tile binding information about （TTA）4 MQH. With these in mind, the X-ray electron spectra of fifteen rare earth complexes （TTA）4 MQH have been studied systematically,

The present note deals with the effects of seawater with different copper concentrations and pH values on the larvae of the barnacle Balanus reticulatus Utinomi. The results show that the higher the copper concentration and the lower the pH value in the seawater, and the more acute the toxicity. In the natural seawater of pH 8.1 the effective concentration EC50, i.e. the copper concentration causing 50%. larvae fail to attach, is approx-
