Based on a detailed study of the gravity anomalies in this area,the authors delineated several important rock bodies and,on such a basis,generalized the gravity and magnetic field marks for qualitative interpretation of magmatic rocks and their modes of occurrence.
在充分研究该区重力异常的基础上,圈定出了几个重要岩体,并据此总结归纳出定性解释岩浆岩体及产状的重磁场标志,建立了该区几种侵入岩体的地质-地球物理模型,且进一步对该区岩浆岩的分布特征形成了新的认识。

By the methods of burrow depth,mark-recapture and burrow account,this paper investigated the Phrynocephalus vlangalii population density on zoige desert in September 2002.
在2002年9月,分别利用洞穴深度法、标志重捕法和洞口计数法对分布在若尔盖草原荒漠中的青海沙蜥(Phrynocephalus vlangalii)的种群密度进行调查,所得的结果分别是190。

During the years of 2001 and 2002,six times mark-recaptures were conducted on Phrynocephalus vlangalii,distributing on Zoigê grassland,northwestern Sichuan to study the growth and the growth differences between female and male(GDFM) living in natural habitat.
为了研究自然生境中沙蜥的生长和两性生长差异情况,于2001~2002两年间对分布在四川西北部若尔盖地区的青海沙蜥(Phrynocephalus vlangalii)进行了6次标志重捕。

Mark-recapture, counting entrances to lizard holes and measuring depth of lizard holes were used to collect data on population ecology of Phrynocephalus vlangalii, distributed in Zuoergaigrassland, Northwest Sichuan, in 2001 and 2002.
利用标志重捕、洞口记数法和洞穴深度三种方法，于2001年和2002年进行了6次野外研究，收集了川西北若尔盖草原青海沙蜥(Phrynocephalus vlangalii)的种群生态学资料，包括：1)标志重捕时间及体长、体重和尾长，2)被捕捉时的空间位置，3)沙蜥洞口数和空间位置，4)沙蜥洞穴深度。
