This paper discusses the method of making accidental error by Montcaro.

笔者讨论了蒙特卡罗法生成偶(然误)差的原理 ,并用模拟的偶(然误)差参于大地四边形平差计算 ,其结果与误差传播定律一致 ,从而验证了蒙特卡罗法用于大地四边形模拟计算的可行性 ,为大地四边形的优化提供了一种可行的有效方

Because of fault in operation and the precision of instrument,the defect error and accidental error are involved in the procession of data collection,the defect error that are brought by mistakes of people and influence of outside is large,the contingency error that are inevitably and randomicity is little.

在采集数据过程中,由于某些操作或仪器原因,往往使数据中包含人为错误,或外界干扰产生的量值较大的“过失误差”以及不可避免的带随机性质且量值较小的“偶(然误)差”。

By comparing the probability of the actual position within various random error patterns with the same arca, the paper inverses the various dimensions of each random error pattern with the same probability, and thus puts forward the considerations of using the random error patterns to judge the accuracy of the ship s position.

通过比较在面积相等的情况下几种船位偶(然误)差图形内船位出现的概率,反推出在概率相等的情况下几种船位偶(然误)差图形的大小,从而得出在使用船位偶(然误)差图形来评定船位精度时应当考虑的事项。
