Based on an introduction of the existing specifications of OpenGIS Consortium, this article not only explores the relationships among OGC specifications and the interoperability of geospatial data as well as geoprocessing services, but also discusses its impact on the development of Chinese geographic information industries.

As a result, if the strength of the lime soil as roadbed packing is determinated according to the existing specifications, it is difficult to reflect accurately its strength properties.

Combining with an engineering instance, basing on the current specifications and a certain construction, the transfer girder structure is analyzed by the method of finite element.

The ultimate bearing capacity of the specimens,calculated by the methods of current specifications and codes is quite conservative,compared with the experimental results.

The model of pile-soil- structure elastio-plastic dynamic interaction has been analyzed and the property of pile-soil- structure elastio-plastic dynamic interaction has been studied in the paper.

Accordingly,based on studying the current VRML standard,a model builder of VRML was developed,which used Visual C++6.0 as the system developing platform,implemented realistic image display of 3D model and dynamic browse by OpenGL,the standard graphic API,and offered visual and interactive manipulation,which made the users construct the virtual scenes based on Web without directly using VRML.

Two simplified formulae, which accord with well known Mononobe-Okabe solution and are convenient for engineering calculation with higher accuracy, are suggested.

This article also identifies possible unsafe cases when unbonded prestressed concrete frames have large horizontal loadings and the limitations of the current codes ACI318-89, BS8110 and JGJ/T92-93. The accuracy of the corrected formula has been verified by comparison with experimental results.

However, if X-machines are to be used in practice as a tool for specification and test generation, there needs to be ways of developing existing specifications into more complex and more detailed versions through a process of refinement.

After 6 h of heating, the amount of Conradson carbon residue and after 16 h the viscosity exceeded that of the existing specifications for biodiesel.

The article also shows the dynamics of the change in the number of rolled products of steel 10 that failed to meet the existing specifications in initial tests.

A general modeling framework consisting of supply, demand, and demand-supply interaction models, and including most of the existing specifications is presented both for the discrete time-discrete flow and continuous time continuous flow cases.

As it is DONG's intention to have general specifications available for new projects, the existing specifications will have to be rewritten.

In the case of years with normal inflows, the total amount of cascade power generation running on current specifications reaches 107500 GWh per year.

These values meet the current specifications for biodiesel, a renewable substitute for petroleum-derived diesel fuel.

The contamination of the deposited aluminium with respect to Ni and Cu was, however, too high to meet current specifications for commercial grade metal.

Current specifications for such materials tend to be restrictive to some extent, however, and in many countries there are separate standards for each admixture.

Current specifications for equipment for diagnostic radiology, nuclear medicine, and radiotherapy

The specification of rolling angular velocity oscillation qualities is studied in this paper. According to the handing qualities specification,the characteristic of rolling angular velocity oscillation is measured against the values of peaks of ωx(t) curve. Because of the nonlinearity of ωx(t) ,the existence of jumping phenomenon of the solution of ωx(t) = 0 , coresponding to the peaks of ωx(t) curve,has been found in this paper. It causes the uncertainty on the evaluation of rolling angular velocity oscillation...

It causes the uncertainty on the evaluation of rolling angular velocity oscillation qualities. This paper calculated the locus curve of zero point of the transfer function ωx/δx(s) while the jumping phenomenon happened ,verified the existence of uncertainty on the rolling angular velocity oscillation qualities, discussed the conditions on which the uncertainty occured, and made some suggestions on the relevant handling qualities specification.

The acting force of sea ice is more important to off shore structures than sea wave force in Bobai Bay, China. The working stress of tubular joints of platform structure very closely related to rupture forms of sea ice. The rupture forms of sea ice are mainly crushing,buckling and bending. It used to calculate the stress only according to one of the rupture forms. Now some rupture forms are considered together in this paper. In the present specification,the fatigue life curve of off shore structure steel under...

In this paper,based on the experimental results of fatigue crack propagation under low temperature and random ice load by Petroleum University,the fatigue life curve and its parameters are given. A new method of fatigue life calculation of tubular joints is put forward in this paper.

The influence of ice force acting on offshore vStructure in Bohai Sea area is more serious than that of the sea wave. The maximum stress acting on tubular joint of offshore platform due to sea ice is closely related to the rupture form of sea ice which consists of crushing, bending and buckling etc. In the calculation of stress in this paper* a few number of rupture forms is considered together at same time, while in the past time, only one form is accorded. Moreover, in the present code, no fatigue life of...

The influence of ice force acting on offshore vStructure in Bohai Sea area is more serious than that of the sea wave. The maximum stress acting on tubular joint of offshore platform due to sea ice is closely related to the rupture form of sea ice which consists of crushing, bending and buckling etc. In the calculation of stress in this paper* a few number of rupture forms is considered together at same time, while in the past time, only one form is accorded. Moreover, in the present code, no fatigue life of steel structure under low temperature and ice load is given, but in this paper, the fatigue life curve and its parameters are given according to the results of experimental test of fatigure crack development under low temperature and random ice load. Based on above, this paper proposed a new method for fatigue life calculation of tubular joint in platform structure.
