Microtremor Survey

A comprehensive understanding of the internal structure and building a geomechanical formation model plays an important role in developing and utilizing geothermal resources. Formation models help in identifying the channel and cycling modes of the heat flow. Due to the urban sprawl and development, constructing a formation model of geothermal resources based on data from traditional geophysical methods is challenging. The Microtremor survey method was adopted to obtain critical information in Jimo, which is famous for rare seawater geothermal resources in China. Three microtremor survey lines were deployed to identify subsurface structures up to 2 km into the ground. Dispersion curves of Rayleigh waves with frequencies from 0.4 Hz to 10 Hz were extracted using the spatial auto-correlation method. An empirical equation was adopted to obtain the apparent S-wave velocity of each survey point, and plot the apparent S-wave velocity sections. The obtained sections reveal the development of two interacting faults. They form a channel for the heat-flow cycle. Two conceptual models were established to depict the formation and cycling modes of seawater geothermal resources in Jimo, based on the results and analysis. The proposed model will help verify the geothermal system and scientifically guide the development of unique geothermal resources . Moreover, the developed model verified that the microtremor survey method is effective and dependable for identifying fracture zones and strata.

Metalworking practice is the link between theory and practice of classroom and workshop, and it is a major practice link of mechanical engineering which plays an important role on course learning effect and on the mastery and ascension of practical application ability. Linking theory with practice is an important theory basis and significant guiding for improving teaching effect of practice, for introducing skills performance appraisal content, for improving the training level and quality, for strengthening the teaching style and discipline construction, for changing the concept of weight theory light practice, for regression of engineering nature of education, for improving the quality of engineering education and for achieving excellence training requirements. In order to change the present situation of weight theory light practice, some method has been present in theoretical teaching and the effort will be effective.

The aim of the study is to analyze attitudes and behavior toward exercise one hour every day by means of questionnaire survey method by using7150 parents of students in primary and secondary schools in Zhejiang province as research object.The result shows parents are very concerned about whether their children is sick,but does not care about whether their fitness is good.Exercise time for most students during weekends and holidays at home is less than one hour a day.Parents have misunderstood to some extent as for the concept of physical training,awareness and exercise behavior.In view of parents’ erroneous zone of manner and behavior on “exercise one hour everyday”,this article put forward the corresponding proposal.

Microtremor Survey

The microtremor survey method (MSM) has the potential to be an important geophysical method for identifying the strata velocity structure and detecting the buried fault structures. However, the existing microtremor exploration equipment has been unable to satisfy the requirements of the MSM, which suffers from low data accuracy, long measurement time, and blind acquisition. In this study, we combined a 2 Hz moving coil geophone with advanced acquisition systems to develop a new integrated energy-efficient wireless sensor node for microtremor exploration. A high-precision AD chip and noise matching technology are used to develop a low-noise design for the sensor node. Dynamic frequency selection technology (DFS) and dynamic power management technology (DPM) are used to design an energy-efficient mode. The data quality monitoring system solves the closed technical flaws between the acquisition systems and the control center via 4G wireless monitoring technologies. According to the results of a series of in situ tests and field measurements, the noise level of the system was 0.7 μV@500 Hz with 0 dB attenuation and 220 mW power consumption of the system in the autonomous data acquisition mode. Therefore, it provides substantial support for the effective data acquisition over long measurement durations in microtremor exploration processes. The applicability of the system is evaluated using field data, according to which the integrated energy-efficient wireless sensor node is convenient and effective for MSM.
