On the convergences of a posterior density determined by mcmc samplers .
mcmc样本确定的后验密度的收敛性。
In order to examine the air quality gradient a transect study need to be establish . The transect study will be sampled using passive samplers .
为检查空气质量等级,应建立横断面研究,横断面研究使用被动取样器取样。
For each sampling period , two samplers were situated adjacent to the outdoor smoking area , with a third sampler located away from the smoking area as a background sampler in the expected upwind direction .
