| 摘 要： | 国内外的台网中总是一些台站，其极性读取似乎是由大量台站Ｐ波初动的整体分布确定的震源机制相矛盾，这些矛盾通常被作为坏读（ｂａｄ ｒｅａｄｉｎｇ）处理，造成台站的极性问题的复杂原因究竟是什么，利用ＮＥＩＣ的核爆资料，文中给出两种可能推测：台站仪器本身的不可和地震本身的复杂性。

| Abstract: | There are always some seismic stations whose polarity readings seem conflict against the focal machanism determined by the whole distribution of P wave first motions in the netWorks all over the world. Such conflicts generally are considered as the bad readings. Using nuclear test data from NEIC, this paper gives out two possible assumptions about the sources making station polarity complicated. disreliable stations equipments and complexity of earthquake itself. |
