The electrostatic and hydrophobic interactions were explored under the condition of different pH values. The results indicated that the electrostatic interaction energy, electrostatic desolvation free energy and hydrophobic desolvation free energy showed smaller values when pH values are between 5.5 and 8.5, which indicated that, under the condition, the electrostatic and hydrophobic interaction were favorable to the stability of SARS 3CL proteinase dimer.

The coefficients of the series formula for the superconducting critical temperature have been determined by using the numerical solutions in which the value of λ is low. The new coefficients can be used not only in the case of small λ, but also in large λ cases.

The discrete-parcel method is a free Lagrangian method, which has many advantages over the traditional Eulerian grid-base numerical methods. It has less numerical diffusion and is more flexible in treating complex ice processes.

For smaller values of λ the nature of the branching depends on the cell side ratio.

It is established that the cobalt-molybdenum alloy undergoes deposition at smaller values of pH (5.0-6.0) than the nickel-molybdenum alloy (7.0-9.0).

For smaller values of g the position of the maximum of d(U) is approximately 3t, and rapidly tends to zero as g approaches gc from below.

Since that time, the dipole value has differed from its present value by no more than an order of magnitude, and the deviations that have already been detected tend toward smaller values.

These results indicate complex along-section SMC behavior distinguished by alternating larger and smaller values of the parameters.

Two methods for analyzing caisson-beams are introduced in this paper.One is the well-known method of redundant forces. The author has simplified this methed by using couples of redundant forces to set up a typical equation and pointing out the rule that the matrix of the coefficients of simultaneous linear equations which are organized from the expansion of that typical equation. This method can be easily solvd when the number of unknown redundant forces, or that of equations, is less than 3 or 4; but it will...

Two methods for analyzing caisson-beams are introduced in this paper.One is the well-known method of redundant forces. The author has simplified this methed by using couples of redundant forces to set up a typical equation and pointing out the rule that the matrix of the coefficients of simultaneous linear equations which are organized from the expansion of that typical equation. This method can be easily solvd when the number of unknown redundant forces, or that of equations, is less than 3 or 4; but it will be difficult when the number is more than that. In order to solve this difficulty the author suggests another kind of method of which the essential principle is mentioned in the following.Supposing that the distance between the beams is sufficiently short in comparing with their spans, we can set up a partial differential equation for its deffiection W, as we often do in the theory of elasticity. In this way we can solve it with its boundary conditions of simple supporting by sine series. From this we can easily get the formulas of bending moments, shears and twist moments of each beam by partially differentiating the function of deffiection. The result of the calculation proves that it quite agrees with the method of redundant forces when the distance between beams is no longer than 1/5 of their spans.There are some tables given in this raper for practical use.

A theoretical analysis of the stress state of right-angled intersections of cylindrical pipes subjected to internal pressure is herein presented. The ratio "v" of the branch pipe to the radius "A" of the main pipe, v=a/A, is limited to small values. In accordance with the formulae derived from theoretical anal ysis, a generalized computer program was drawn up and applied to two numerical examples on type 709 computer. Results obtained are given at the end of this paper.
