The parameters of 34 cross sections(n=34)were measured or calculated at end-diastole with IVUS,which included lumen circular shape factor(CSF-L),circular shape factor of external border of the intima(CSF-I),circular shape factor of external border of the media(CSF-M),etc.

All cases were non-Hodgkins lymphomas ( NHL). Twenty cases were muco-sa associated lymphoid tissue (MALT) lymphoma, and 13 of 20 cases were extra-nodal marginal zone B-cell lymphoma of MALT.

The results show that the performance of the hexagonal planar array could be greatly improved by thinning,the maximum relative sidelobe level was reduced by 7 5～9 4dB,and thinning partially the array could attain the same performance as that of fully thinning.

The apoptosis index of hepatocytes and biliary epithelial cells within 2 cm to the edge of coagulated region in the experimental group was higher than those in the control group(P<0.01).

Other labeled neurons were located along the external border of the external plexiform layer; the scarce neurons marking its internal border were identified as van Gehuchten cells.

This study was conducted in June and July 1995 at two sites in the bay, one located at the center of the muddy fine-sediment community and the other at its external border with the fine clean sands of theOphelia borealis community.

In all these cases, preperitoneal and retromuscular polypropylene mesh was used as a reinforcement and was subsequently attached by means of absorbable sutures to the external border of the rectus muscles.

about 14 AU in Taurus)we have been able to access the external border of the acceleration region, for jets in the Taurus-Auriga cloud.

The range of applicability of the proposed algorithm is quite wide: it can determine the external border of a simply connected region as well as the external and internal borders of a set of multiply connected objects, all at the same time.

The boundary conditions which this solution must satisfy at the outer edges of the boundary layers which develop at the walls are considered.

For surfaces with a low level of catalytic activity the accuracy of simulation of the nonequilibrium heat transfer is determined by the deviations of the temperatures at the outer edges of the boundary layers on the body and the model.

This current in the Jovian magnetosphere flows only along the preferential magnetic surfaces that connect the inner and outer edges of the disk to the ionosphere.

It is suggested that the phosphorites were formed due to the high local biological productivity over the outer edges of coral reefs and are not related to guano accumulation or to endoupwelling.

The shells are subjected to unifromly distributed lateral loading and are simply supported at outer edges whereas inner edges are absolutely free.

In the 1976,a tibiotarsus of fossil bird was obtained by a field party of theInstitute from Xichaun district,Honan Province.This is the first time that fossil birddiscovered from the Lower Eocene of China.Materials was found from the bed of Yu-Huang-Ding Series.Described in this paper represent 1 genus and 1 specis:Zhongyuanus xichuanensis gen.et sp.nov.Diagnosis:The outer articular condyle extends beyond the line of the outer sideof tibiotarsus;outer articular condyle forms a “V” angle with that of the inner...

The three-convolution circular are corrugated diphragms(see Fig.1) are now in common use. Their outer fringe circular are wave varys in measurement. The waves of diaphrams are all in the shape of circular arc, but the characteristies, stress values and effective areas of the diaphragms themselves are different, owing to their different outer fringe waves.

The three-convolution circular are corrugated diphragms(see Fig.1) are now in common use. Their outer fringe circular are wave varys in measurement. The waves of diaphrams are all in the shape of circular arc, but the characteristies, stress values and effective areas of the diaphragms themselves are different, owing to their different outer fringe waves. This paper, by means of toroidal shell theory (see V.V. Novozilov[1])and initial parameter method of numerical integration, presents the calculation of three-convolution circular arc corrugated diaphragms with various outer fringe waves, compares the results of the calculation with experiments (see W. A. Wildhack [3]) and with orthogonal anisotropy plate theory (see L, E, Andrewa[2]). Through much calculation the the paper works out some fitted formulae for three types of three-convolution circular arc corrugated diaphragms with various outer fringe waves and for general cases with an arbitrary measurement of outer fringe circular arc wave. These formulae can be applied to calculating the characteristie and maximum composite stress of a diaphragm, when the diaphragm is subjected to a uniform pressure or a concentrated load at the center. They can also be applied to calculating the effective area of the diaphragm. These formulae are not only reliable but also simple and convenient for engineering workers who can use them with only pocket calculators. This paper also discusses the influence of outer fringe wave on design of corrugated diaphragms and shows that when diaphragms are subjected to uniform pressure, the larger the outer fringe wave is,the higher the sensitivity of the diaphragms and the smaller maximum composite stress. The sensitivity of symmetrical corrugated diaphragms is low, their composite stress is big, but their characteristics in two directions are identical. When diaphragms are subjected to concentrated load, the influence of outer fringe wave is slightly different from under uniform pressure. The effective area of diaphragms is, by and large, independent of the measurement of outer wave. Finally, the paper gives an example showing the way to design a diaphragm with the fitted formulae.

Long cantilever slabs are often used in trapezoidal box girder bridge, Thehighway bridge design specification in our country provides the design formulafor constant thickness, but no provisions are related with variable thickness.In this paper, applying Finite Difference and revised Finite Difference, theeffective width of load on the cantileve deck are analyzed.
