通过对南京台短水准测量中的基岩标志和土层标石的抗干扰分析发现：温度、气压的影响可以通过改变观测时间段来尽量减小，使其对两类观测点观测资料没有明显影响；降雨量的大小对基岩点的影响很弱，但对土石点的影响较大，则没办法消除。表明在选择好的观测场地的同时，也要根据观测资料的需要埋设合理的测点标志类型。
The the Nanjing Short-standard measurement of bedrock flag and soil Stone's anti-jamming analysis found that: the influence of temperature, barometric pressure can change the observation period to minimize the two types of observation points observationshad no significant effect; the size of the rainfall, bedrock point is very weak, but the debris point, you can not eliminate. That good choice of observation sites, but also the measuring point mark type were planted according to the needs of the observational data.
