- trigonometrical hypsometer 三角法测高器
- Graphs trigonometrical functions (which are evaluated by the application) that you enter freeform or select from a pre-populated list. 这是一个图形三角函数，你可以选择一个自由形式或从预生成的列表中选择一个。
- And trigonometrical function table checking method is referenced to reduce large arithmetic amount in the unwrapping process. 并使用三角函数查表法减少了展开过程的运算量。
- When the hypsometer is used with static level gages, which are installed on the top and base of the dam, the altitude data transmission can be realized in real time. 若将传高仪与坝顶布设的静力水准仪和廊道内布设的静力水准仪相结合应用，则可达到实时自动传递高程的效果。
