The hospital's wastewater plant have no data about quantity, quality and record of operation. 该医院污水处理站在没有污水的水量、水质数据、生产运行记录及设计、竣工资料的条件下。
Fur seismic exploration in mountainous areas, the accuracy of time break ( TB ) signal is vital for the quantitative analysis of seismic data acquisition and quality control of seismic record. 在山地地震勘探中,时断信号的准确性是资料采集量化分析和地震记录质量评价的重要方面。
Comparing and analysing their test data, it is shown that in order to ensure quality of record data, the horizontal pendulum scale should be calibrated by the " microairflow " method when station have lack of condition of the " crapandine jump " calibration method. 对比分析了它们的实验数据后认为:为保证水平摆观测资料的质量,在暂无条件使用胀盒阶跃法标定的台站应采用微气流法标定水平摆格值。
Each method has a good effect for the data record which has a well first arrival quality. But with the reduction of the record quality, the reliability of first arrival wave by automatic pick is worse and worse. 针对初至波的自动拾取有很多计算方法,这些方法对于初至质量好的记录都有着不错的拾取效果,但是随着记录质量的降低,自动拾取的初至可信度越来越差。
