Compression tests were made at -196 to 200℃ using specimens from 5083-O sheets in the longitudinal, long transverse and short transverse directions. α(=b/a) (ratio of lengths of the minor axis(b) to the major axis(a) on the elliptical cross section of the middle of specimens during compressive testing) is the value showing anisotropy of specimens. A linear relation lies between α value and r'valur on the compressive testing which is similar to the r value on the tensile testing.

The probability distributions of water quality in eutrophic lake and in a polluted river are estimated by order statistics with 60 samples. The data are collected by the Depertment of the Water of Chiba Prefecture in Lake INBA and in KANNOU RIVER in april 1976-March 1980. The distributions can be classified into three types which are normal, lognormal and exponential distributions. The goodness of fit of the probability density functions are tested by means of Kolmogorov-Smirnov tests.

The purpose of this report is to investigate the learning attitude and the interest of both Chiba University and our college students through the same questionary and the same mathematics test. We have tried to find the difference of their learning attitude and interest. Certainly, there are some specific differences among them. We believe that this research will brush up our teaching-method once we know the actual state of their learning attitude and interest.

Twin Blumlein-driven TE N2 laser channels of almost identical shape and dimension were constructed using ceramic capacitors. The channels had an active length of 500 mm and electrode spacing of about 22 mm. The maximum output power (15 KW/pulse) and the E/P value (120V/cm・torrs) were obtained at a repitition rate of 10 Hz.

Recently, complexity of calculating formulae is a small matter because we can use a computer for it.In this paper the author compares Newton method, Bailey method and Regula Falsi method with computing primary equations and shows Bailey method makes the fastest finding solutions. The author expresses Newton method and also Bailey method should be lectured in computer mathematics.
