In the design and application of neutron guides, it is very important to simulate neutrons transmission by Monte-Carlomethod.
利用蒙特卡罗方法模拟中子在导管中输运过程，在中子导管的设计和实验应用中可发挥重要作用。

HHTM, including both heterostructure effect and nonstationary transport effect such as velocity overshoot effect, expends much shorter calculating time than Monte-Carlomethod.
HHTM既包含了异质结效应，又包含了高场输运中的速度过冲等非稳态输运效应。
