Regarding the freezing of foods as the thermal shock, an approximate analytical solution of the the; mal stress occuring within the erived a nd compared with the experimental results. To solve this problem, the solid phase is assumed to be a elast o-plastic free plate according condi-ti on and the temperature distribution in the solid phase is calculated from the ximate Neumann's solution, with convection at the surface, presented by authors. The thermal stress profile estimated by this solution is in the experimental results.

The initiation and propagation processes of stress corrosion cracking (SCC) of austenitic stainless steels in boiling 35% MgCl
2, pH 3.0 were investigated electrochemically by means of separating the crack anode from the cathode. The dissolution current can be measured by connecting the anode with the cathode through an external electric circuit, as the result the distinction of the crack initiation and propagation becomes very easy. The simulation of the short circuit condition by keeping the crack anode potential at the potential of cathode using a potentiostat makes the coupled potential not to fall accompanying the crack propagation and accelerates the dissolution of crack anode to fail. For materials and environments which have low susceptibility to SCC, it can be cleary decided whether the SCC occurs or not to compare the critical potential for the crack propagation, not the initiation, with the rest potential of the steel in the considering environment. If the former is less noble than the latter, SCC can occur.

A theoretical analysis has been performed on the stability of a contracting liquid jet issued downward into the atmosphere by applying approximately the stability theory for a cylindrical liquid jet. It was found consequenly that the laminar breakup length of a contracting jet is longer than that of a cylindrical one, and is not linearly proportional to the jet velocity. Furthermore, it was found that the diameter of drops formed by the disintegration of a laminar contracting jet depends upon the nozzle diameter, the jet velocity and the surface tension of liquid, and nearly not upon the liquid viscosity.

By applying the diffusion current method, liquid film coefficients of mass-transfer are measured for single sphere or sphere arrays, both immersed in a free liquid stream of uniform velocity. Measurement is also performed for an active sphere placed in a packed bed of dummy glass beads. The concept by Cornish for the lowest Shp is examined from the data obtained by the sphere arrays. Determining the lowest Shp from the packed bed runs is shown difficult, since there is no indication of Shp to approach a certain lowest value under the flow condition tested. The packed bed data are correlated as follows: jna=1.0/Reh
2/3 for 10
-3<Ren<5, and jnh=0.75/Reh
1/2 for 5<Ren<10

A new method for calculating the terminal compositions of a multicomponent rectifying column, giving optimum feed plate location for the maximum separation of key components for a given value of reflux ratio, total number of plates, rate of distillate and feed compositions, was proposed.
Numerical examples showed the method was of very much useful for reducing computing time and for designing purpose.

Particle trajectories and particle precipitating efficiencies η
w. in a two-dimensional nozzle are numerically calculated by using Rosenhead's equation of fluid velocity distribution in the region, where gravitational and inertia forces mainly affect on the particle motion. The experimental data obtained in the same region are compared with calculated ones, and the mechanism of particle precipitation on a nozzle wall are discussed. In consequence the following results are obtained.
1) This model seems to represent fairly well the mechanism of particle precipitation on a twodimensional nozzle wall.
2) When dimensionless precipitating velocity G is larger than 0.005, η
w is not negligible, i.e.η
w≠0.
3)ηw, is also influenced by inertia parameterψ. When ψ 0is large, η
w, can not be neglected even if G is small.
