The Design and Accomplishment of the “Computer Communcation Wild Area Network of the Social Development Bureau of the Shanghai Pudong New Area ”—— The Design and Accomplishment of a Open Structure System Assemble
4. The textbook should help students establish an open structure of knowledge anddevelop self-development capability.
Moreover, it embodies the essential of object-oriented technique by the open structure of AutoCAD core database and ObjectARX base class, class inheritance and mechanism derived to define the special object-class.
Compared to the normal steel cords with 1×5×0.25 or 3+9×0.22 compact structure,the high tensile steel cord with 2+2×0.30 HT open structure features better physical properties,extruding and calendering behaviors,performance of finished tire and lower price.
The problems and trends of the steel cord in belt of radial light truck tire are presented,and the properties and application of the high tensile steel cord with 2+2×0.30 HT open structure are described.
Based on the analysis of the three typical 3D woven structures,the basic structure cells,that is,the orthogonal,pseudo-orthogonal,angular interlocking and open structure cells,are first defined according to their structure characteristics.
In order to overcome the difficulties in solving acoustic problems of open structure for both IDBEM and DBEM,a new formula called virtual boundary method is presented. In this method,some virtual boundaries are added to the structure,thus make the open structure be closed and separate the acoustic region into two independent regions,i. e.
Ion displacement contributes to ? along the bedding at low frequencies.4.The temperature dependence of tan δ indicates that coal has a very open structure along the bedding and that conduction dominates the loss in that direction.
The compounds formed by the condensation of the indoline derivatives with 3-formyl-4-hydroxycoumarin have an open structure of the merocyanine dyes and are transformed into spiro forms neither in the dark nor under irradiation with the visible light.
The open quinoneimine structure is retained upon replacement of the tosyl substituent by a less bulky electron-withdrawing acetyl substituent, suggesting that electronic factors are decisive in formation of the open structure.
These results showed that the effect of the open structure present in the TiO2 amorphous phase provides the atomic mobility required for the crystallization.
The reason of having larger Ag particles at lower temperatures in the latter set of samples is probably because they have a more open structure, produced by a wider distribution in the Si-O-Si bridging angle.
