This paper is to describe the characteristics of the Small Towns development in Rural China. The policies to develop Small Towns have been induced for solving the problem raised during the rural reform. The changes and adaptations of rural reform processes are integrated in Small Towns. The characteristics in the process of development of Ronggang, a small town, are as follows. First, it was the fund raised by rural inhabitants that was used for construction and development of the small town, Second, by implementing the policies of selective migration, the inhabitants of the small town have been differentiated from those of rural region. Third, the activities of commerce and industry of Ronggang have progressed to joint-stock system. Fourth, Having the spatial characteristics of self- development, the small town has grown and is expected to grow higher hierarchy of settlement system.

The motion of a small boat in seas is affected in relatively higher degrees than the case of a larger ship by the specific characteristics of sea waves, i.e., the wave length and height. Ship's motion caused by sea waves is a matter of special importance to small fishing boats, because they carry out fishing job in rough seas frequently. This is an experimental study on the rolling and pitching motions of full scale ship. In the experiment, the ship's motions were measured for head, how, beam, quarter and following seas. The experiment were carried out on board the training ship Pusan 404(160 GT) in the adjacent waters off NAM HYENG JAE DO on Dec. 13th 1994. The sea condition during the measurements was that wave height 2.5m, no swell and the wind velocity of 12 m/sec. Some statistic considerations were given to the observed data by the series analysis methods and discussed in this paper.
