Does allogroomiog serve a hygienic function in the sichuan snub - nosed monkey to test the hygienic functional hypothesis of allogrooming in the sichuan snub - nosed monkey, we analyzed the distribution of such behavior over the body surface of individuals in the west ridge troop in the yuhuangmiao region of qinling mountains, shaanxi province, china. based on 113 days of observations of the troop, 293 allogrooming bouts were obtained by focal - animal sampling. we divided the body surface of the monkeys into 17 areas
第二章川金絲猴的理毛行為是否符合衛生功能應用目標動物取樣法，在113天的跟蹤觀察（有效觀察時間351小時）的基礎上，收集了293個相互理毛回合（ bout ）的數據，對秦嶺川金絲猴（ rhinopithecusroxellana ）玉皇廟西梁群個體間的相互理毛進行了分析，檢驗相互理毛是否符合衛生功能假說（ hygienicfunctionhypotheses ） 。 -
The unfocused aspherical surface system is one of the main structure of large emiting system. in the system, the more large the relative aperture of primary mirror, the more small the focal length and the tube of system, and the more light the weigth
這個系統中的主反射鏡的相對孔徑越大，其焦距就越短，相應地系統筒長就越短，重量就越輕，這樣就越能滿足車載或機載系統的實戰要求。 -
If the focal point of the len shifts around the surface of the sample, the mass ablation, the temperature of the plasma and the spectral intensity appear asymmetric and their maximum occur at the location which is about 0. 4mm under the surface of the sample. ( 2 ) to the plasma of the aluminum alloy sample, when the operating voltage is 1600v, the height from the observed location of the plasma to the surface of the sample is 2mm and the argon pressure is 660 torr, the spectral intensity have the maximum values
（ 2 ）對于標準鋁樣品，在激光器工作電壓為1600v 、等離子體觀測高度為2mm 、氬氣壓力為660乇時，其譜線強度最強；以al 308 . 22nm 、 al 309 . 27nm兩條譜線為分析線，發現隨著環境氣壓的增大，譜線自吸效應明顯增強，當環境氣壓達到600 - 700乇時，譜線幾乎產生自蝕。 -
The primary mirror. this is the paraboloidal mirror at the bottom of the tube. it has an aluminized surface that reflects starlight to form an image at the focal plane
主鏡。是位於鏡筒底部的一塊拋物面鏡。表面鍍鋁膜，將星光反射到焦平面上成像。 -
