In view of the sudden collapse phenomenon of some bridges in their construction process in recent years,this paper proposes suggestions to the accuracy analysis of stress monitor in bridge's construction control and mainly introduces as how to remove the error of stress monitor caused by various reasons in the monitor process.
It analyzes and generalizes the special detection technique of the steel concrete bridge lasting hazard,and brings forward some measures to improve the durability of the steel concrete structure at last,which will make the supervision of the steel concrete bridge lasting hazard better.
This paper describes the deformation of non-contact 3D total station tunnel observation technologies,focuses on the basic components of the system,and pays attention to the principles of free stations,deformation monitoring of the application and development of a guide.
The wind turbine imitation system includes not only a hardware platform composed of PC, data-collection board and thyristor-based velocity-regulator, but also monitor software of wind turbine imitation.
For this paper, GREENSPAN sap flow system was used to monitor the dynamics of trunk sap flow of Gingkgo biloba.
A new method is developed to monitor joint quality based on the information collection and process in spot welding.
Results show that all of the models can be used to monitor joint quality.
It is important to be able to monitor and estimate forest biomass and production, regional carbon storage, and global climate change impacts on these important vegetation types.
Fr?nsdal [Fr1, Fr2] made a penetrating observation that both of them are quasi-Hopf algebras, obtained by twisting the standard quantum affine algebraUq(g).
Finally, the results obtained are applied to assessing the influence of individual observation, with the aid of an example.
Chemical and physical reactions during the low temperature aqueous chemical synthesis of nanostructured Bi2Te3 powders were investigated in-situ by pH measurement, color observation of the solution and X-ray diffraction analysis of the powders.
High-resolution transmission electron microscopy observation indicates that the nanocapsules are hollow-structured with a wall thickness of about 6 nm.
