| Abstract: | In order to study the environmental factor problem for liquid rocket engine, we put forward a new method named modification inverse moment estimation method, based on the method proposed in 1]. Compared with the existing methods, the new method is especially superior for small sample problems. In the end, a numerical example is given to illustrated the efficiency and validity of the new method. |
