The system gets two image of one object with two CCD, thus obtains depth from two CCD"s parallax. After investigating the operation spot and discussing with surgeons we use LED as markers, and get the marker"s 3-D position with a non-contact optics orientation method. After calibrating the CCD, processing the image, the system can figure out marker"s areal coordinates, get marker"s 3-D coordinate in dummy world coordinate system, thereby obtain instruments 3-D position and orientation. After the coordinate transformation and a series of orientation calculation, operation navigation comes true.

Here we clarify that areal-type of a genus is defined by concluding distributions of all species in the genus, therefore specific distribution types are not the same as their generic areal-types except monotypic genera. Similarities of composition of areal-types between compared regional floras do not necessarily represent their floristic similarities because the same generic areal-type can be composed by different genera from different plant families.

Tropical montane rain forest was investigated in Mengsong, south-west to Jinghong City ofXishuangbanna region in the south of Yunnan near the border between China and Myanmar. There are 623 species of seed plants belonging to 327 genera and 116 families in this forest. Analysis of areal types shows that 32.8% of the families are of tropical and subtropical type, 23.3% tropical to temperate type, and 18.1% typically tropical type. Areal types at generic level mostly are tropical (81.4%), in which 28.4% are of Indo-Malaysian type and 26.8% are of pantropic type.

One hundred and thirty four families, 578 genera and 1197 species are recorded in this area. According to the information of historical geology and natural conditions, the composition of seed plant flora and the areal-types of genera were analyzed. The results showed that its origin was rather ancient and its geographical compositions were complicated. There were many species of rare and endangered plants, e.g. Taxus chinensis var. mairei, Bretschneidera sinensis, Emmenopterys henryi, Fokienia hodginsii, Torreya grandis, Phoebe bournei, Ormosia henryi, and so on. Most of these plants had high value in economics and scientific research. According to statistics and analysis of genera in the present flora, 578 genera were divided into 14 areal-types. The ratio of tropical and temperate genera was respectively 48.6% and 49.2%, so its flora was characterized by transitional floristic elements, and in wide connection with the world.
