Abstract We report the results on the preparation of YBCO superconducting tape by dynamic MOCVD on a Ag/Ni substrate continuously-moving at a speed of 15 cm/hr. The YBCO superconducting tape prepared has a Jc value of 1. 3 × 104A/cm2 (78K, 0T),and consists of principle phase of YBCO123 with a high degree of c-axis orientation.

In this paper, application of principle of remote sensing to earthquake prediction is studied and an experiment was made,the experiment has obtained the infrared radiant characteristic and the radiant temperature of rock varying with the stress of rock,the variational order of radiance 10-5(W/cm2. sr. μm) ,the variational quantity of the radiant temperature 0. 2℃-0. 8℃ ,and some significant precursor information was discovered.

In this model, abstraction of general function, confirmation of principle solution to general function, and functional decomposition were included in FA.

Confirmation of principle solution to general function was the premise of functional decomposition.

Rozenshtok [4] considers the problem in an adequate statement but, unfortunately, he permitted errors of principle to enter into the writing of the system of characteristic equations; this led to absolutely invalid results.

Reconstruction of Vendian climatic conditions on the East European Craton is of principle importance for elucidation of the Ediacarian biota habitat.

The observed differentiation was confirmed by the analysis of the polymorphic markers variance by the method of principle components.

It is pointed out in this paper that the following apparent discrepancies exist in Coulomb's Theory: (1) In any problem in mechanics, a force to be definite must have all the three factors involved under consideration. In Coulomb's Theory, however, the point of application of the soil reaction on the plane of sliding is somehow neglected, thus enabling the arbitrary designation of the obliquity of the earth pressure on the wall to be equal to the friction angle between the wall surface and soil. As a matter...

It is pointed out in this paper that the following apparent discrepancies exist in Coulomb's Theory: (1) In any problem in mechanics, a force to be definite must have all the three factors involved under consideration. In Coulomb's Theory, however, the point of application of the soil reaction on the plane of sliding is somehow neglected, thus enabling the arbitrary designation of the obliquity of the earth pressure on the wall to be equal to the friction angle between the wall surface and soil. As a matter of principle, the point of application should never be slighted while the obliquity of the earth pressure could only have a value that is compatible with the conditions for equilibrium. (2) If the point of application of the soil reaction is taken into account in the problem, the sliding wedge would only tend to slide either on the plane of sliding or on the surface of wall but not on both at the same time, thus frustrating the very conceptidn of sliding wedge upon which Coulomb's Theory is founded. (3) The above discrepancies arise from the fact that the shape of the surface of sliding should be curvilinear in order to make the wedge tend to slide as desired, while Coulomb, however, adopted a plane surface instead. (4) Coulomb, in finding the plane of sliding, made use of the maximum earth pressure on the wall (for active pressure), which refers to the different magnitudes of pressure corresponding to different assumed inclinations of the plane of sliding. But from the relation between the yield of wall and amount of pressure, this maximum value is really the minimum pressure on the wall, which it is the purpose of the theory to find. In engineering books, however, this terminology of maximum pressure has caused considerable confusion, with the result that what is really the minimum pressure is carelessly taken as the maximum design load for the wall. How can a minimum load be used in a design?This paper also attempts to clarify some contended points in Rankine's Theory: (1) It is claimed by Prof. Terzaghi that Rankine's Theory is only a fallacy because of the yield of wall and that of the soil mass on its bed. This charge is unjust as it can be compared with Coulomb's Theory in the same respect. (2) Some books declare that Rankine's Theory is good only for walls with vertical back, but it is proved in this paper that this is not so. (3) It is also generally believed that Rankine's Theory is applicable only to wall surfaces with no friction. This is likewise taken by this paper as unfounded and illustration is given whereby, in this regard, Rankine's Theory is even better than Coulomb's, because it contains no contradiction, as does Coulomb's.

This article deals with two problems involved in the relation-ship between load applied to a structure and the deformation induced thereupon. When a member is subjected to a load, the direction of the induced deformation is in general noncoincidental with that of the load, except in special conditions. Furthermore, when a load is applied to members linked together, the directions of loads distributed to different members are not necessarily the same as that of the applied load. Based on these findings, the author...

This article deals with two problems involved in the relation-ship between load applied to a structure and the deformation induced thereupon. When a member is subjected to a load, the direction of the induced deformation is in general noncoincidental with that of the load, except in special conditions. Furthermore, when a load is applied to members linked together, the directions of loads distributed to different members are not necessarily the same as that of the applied load. Based on these findings, the author makes further amendments to principles set forth in papers "Numerical Analysis of Continuous Frames in Space" by James Michalos and "Application of Principle of Moment Distribution in Mathematical Analysis of Agricultural Machinery Structures" by Hou Zhi-ming, and proposes methods of evaluation of coefficient of load distribution and coefficient of load transfer

A general review of the strengthening characteristics of the nickel-base superalloys and a primary study of principles of alloying of nickel were described. Three types of strengthening mechanisms of nickel-base alloys: solution-hardening, precipitation-hardening, and grain-boundary hardening, are discussed.
