| Abstract: | y the use of the conceptions of random walk such as transition probability matrix,mathematical expectation of stay number,etc.,a formula is derived,by which the best possible value of differential aItitude between two points can be calculated simply and conveniently. And a formula for precision estimation has also been derived.An example is given to illustrate the application, and the resuIt obtained is correct. |
