Durability and Service Life Prediction of Concrete Subjected to the Combined Action of Freezing-Thawing, Sustained External Flexural Stress and Salt Solution
The method How design standard rivet's CAD system in AUTOCAD 2000 is introduced in the paper,and develops the exterior DBMS's technology and interface ASI through ObjectARX application,especially expounds on the designing of communicate interface ASI between CAD system and DataBase。
This text explores the fantastic spaces of Meizhou Hakka Round-Dragon Houses from the follow- ing three aspects, namely, exterior space, interior space and physical comfort of space.
With the development of the world economy,the environment problem is increasingly rigorous and becomes the most typical and negative exterior behavior.
As PIC16F877 has no priority of outer interruption requests,a method of using priority encoder 74LS148 to expand its outer interruption requests is proposed.
When there are several outer interruption requests,74LS 148 sorts them according to their priorities first,the request with higher priority is then sent to the interruption input of PIC16F877.When the interruption is processed completely,PIC16F 877 waits for next interruption request.
For the GFA model, thirty molecules were used as training set and eight as test set to evaluate the external predictability of the equations generated using GFA.
For the GRA model, thirteen molecules were used as training set and three as test set to evaluate the external predictability of the equations generated using GFA [r2 = 0.650 and r2pred = 0.807].
If is a ?2-grading of a simple Lie algebra, we explicitly describe a-module Spin0 () such that the exterior algebra of is the tensor square of this module times some power of 2.
We show that the structure of a block outside the critical hyperplanes of category O over a symmetrizable Kac-Moody algebra depends only on the corresponding integral Weyl group and its action on the parameters of the Verma modules.
The resulting Taylor series can be evaluated far outside their radii of convergence-by means of appropriate methods of analytic continuation in the domain of complex perturbation parameters.
Based on the theory of diffraction and the fundamental theory of electromagnetism, Bilow's diffracted current basis function was modified both within and outside the transition regions.
For example, we study Plemelj-Calderón-Seeley-Bojarski type splittings of Cauchy boundary data into traces of 'inner' and 'outer' monogenics and show that this problem has finite index.
It was suggested that the mechanism for the eruption of heat was that La3+ ion damages the outer cell membrane and increases its permeability and the proton-electron potential energy across the cell membrane was reduced or couldn't even be initiated.
