Seven-freedom unit used for analysing the warping of rectangular section beam;

Calculation of bended structural member reinforcement of rectangular section of reinforced concrete;

A spedal study is conducted of the effect of the rectangular section circulating bed edge angle on the gas-solid dual-phase flow and the radial porticle conecntration distribution.

This essay offers the calculation of magnetic field along axis of finite long rectangle section spiral tube current,gives the resolution formula and illustration of the magnetic field, and draws some significant conclusions by discussing on the calculation.

The formula prescribed in Code for design of masonry structures, aimed to calculate influence coefficient (φ) for bearing capacity of biaxial eccentric rectangle section compression masonry members, is numerically analyzed, its bearing capacity would increase when its eccentricity of loading is added, a new substitutive .

This paper offers the formulas of calculating the ledger beam strength, compares the bearing capacity of the ledger beams with that of rectangle section beams.

After numerical simulation validity was confirmed by experimental results on cold model test,the erosion property in a circulating fluidized bed(CFB) with a rectangular cross-section was analyzed using numerical simulation under the condition of different primary/secondary air ratio,different up/down secondary air ratio and different front/back secondary air ratio.

By analyzing all of the factors which will affect the eccentric distance limits of eccentric compression for rectangular cross-sections in this paper,it is believed that the eccentric distance can not be taken as the basis of eccentric compression,other.

A practical formula for calculating the conductance of the tube of rectangular cross section in the full pressure range has been obtained based on a viewpoint that was proposed by the author.
