延寿跨断层短水准测量误差性质及其来源的讨论

DISCUSSION ABOUT THE CHARACTER AND SOURCE OF SHORT WATER LEVEL ERROR ACROSS THE FAULT IN YANSHOU

本文应用数理统计的理论、方法对延寿跨断层短水准1988 年至1994 年计46 期观测成果进行了数理统计处理t 分布检验，对其检验结果结合测线的布设、场地情况，干扰情况以及施测条件等因素加以综合分析，认为观测成果中系统误差是客观存在的。据此采取相应的改进措施，利用改进措施后的观测成果进一步做t 分布检验系统误差得以减小。

Mathematical statistics is used here to dispose the short water level observing resutls across the fault from 1988 to 1994 (T distributing inspection). And based on the analysis of observing results combing with open space interfering circumstances working condition, we regard the system error of observing results as notable. So we can take the improving measures to make the system error of observing results disappear.
