microseism造句
1 In recent years , the research of microseism has made some progress in civil engineering realm .
2 High frequency vibrations did occur early in the microseism, and then the frequency was attenuated because of the damping of rock but not by the frequency dispersion of surface waves.
3 The application of microseism controlled blasting technique during construction, as well as the construction technique of the resin tensile anchor bolts, are introduced also.
4 The technology of real-time microseism monitoring in the operation-involved area of oil field is an interesting research topic.
5 The data of microseism, wind speed and air pressure are processed by using the low-pass and band-pass digital filters.
6 The space of the extremum mine microseism is closely connected with the high stress zones.
7 Some feasible standards and methods about discerning microseism signals are put forward and reliable observation results are obtained in several cases around the world.
8 Microseism, as a kind of regional monitoring means, is used to predict and forecast the great dynamic force calamity of the mine.
9 On this basis, from the enterprise microseism bedding plane, it develops and gives the synthetically study frame about resource, ability, surround environment and compete superiority.
10 Random noises have uniform rules and they comprise of circumstance noise, measurement error and ground microseism.
11 By designing the inner surface curve of the stator, the delivery microseism of pump can be reduced to zero theoretically.
12 This paper emphasize in study of mechanism of vibration frequency for free site in microseism testing.
13 Studied the shock bump caused by the key stratum movement in Huafeng Colliery using the microseism locating and monitoring technology.
14 Theoretical analysis and experimental results show that the method has the effect as same as Hall sensor in the event that ensure the DC motor start-up quickly and microseism, and no locked rotor.
15 The result shows that, there is a rather well corresponding relationship between the anomaly region of seismic apparent strain and the microseism earthquakes.
