Problems with the application of heptane and isoheptane values as light hydrocarbon parameters

Autor: Wang Peirong, Xu Guanjun, Zhang Dajiang, Xiao Tingrong, Ren Dongling

Publikováno v: Petroleum Exploration and Development, Vol 37, Iss 1, Pp 121-128 (2010)

The light hydrocarbon data from 772 oil samples in 25 oilfields, together with GC/MS data from 338 saturated hydrocarbon samples were used to discuss the relationship between kerogen types, using the heptane value, isoheptane value and C29 sterane 20

A portable sub Hertz ultra-stable laser over 1700km highway transportation

Autor: Jiao, Dongdong, Xu, Guanjun, Gao, Jing, Deng, Xue, Zang, Qi, Zhang, Xiang, Liu, Tao, Dong, Ruifang

We present a subHz linewidth portable ultrastable laser with the mass and volume of are 40kg and 400mm*280mm*450mm, respectively, that meets the requirements of automatic frequency locking and road transportation. A dynamic analytical model of the ph
