characteristic velocity
1.The paper presents a model of turbulent flow, which can exactly provide data of the characteristic length and velocity of turbulent flow.
2.The main study results of depth seismic sounding in the northeastern margin of Qinghai-Tibetan plateau(32°-40°N,100°-108°E) are reviewed and summirized in this paper. The crustal structure characteristic of seismic wave velocity and the shape of the Moho in this area are given.
3.Conclusions:The Doppler spectrum of CFV in moderate and severe TR group is characteristic with high atrial reversal velocity and long duration.
4.1. Simulating the air swirl flow field of BG-130/3.9-450 pulverized coal boiler, and expounding the flow characteristic and distribution of air velocity.
5.Through setting up high velocity oxygen/air fuel spray the numerical model of field sheds, carrying the numerical simulation to high velocity fuel spray velocity characteristic and temperature characteristic of particle, its result has announced high velocity oxygen/air fuel spray particle change laws of velocity and temperature.
6.Three characteristic features,such as average velocity of sound,deviation coefficient of sound velocity,and deviation coefficient of amplitude are extracted from four kinds of testing data which are sound velocity,amplitude,frequency and waveform in this paper.Fuzzy analysis and artificial neural network are combined to form an intelligent system with similar functions to human brain to classify GRC,aerated concrete,hollow brick,solid brick and concrete block.The accuracy of this system is up to 95%in field tests.
7.According to the ISO 230-2 standard to deal with the data, this paper analyzes the CMMs single axis stability and interrelated characteristic among axis under different velocity to realize the dynamic calibration which is more accurate than the static calibration.
8.(5) The long-period cumulative settling characteristic and the dynamic characteristic including dynamic stress, dynamic deformation , vibrating velocity, vibrating acceleration reduced with the increasing of height under train load.
10.In the thesis, it includes: 1. Based on the characteristic of INS, a error mathematics model of "velocity+attitude" matching scheme in transfering alignment is stated.
