The climate of most loess plateau gully area is continental monsoon climate. It is hot , dry, sometimes rain-storm in summer, and cold, windy, occasionally snow in winter. The summer and the winter ar...
Effect of peat quality on microbial greenhouse gas formation in an acidic fen
peat quality microbial greenhouse gas formation an acidic fen
2010/1/21
Peatlands play an important role in the global carbon cycle and represent both an important stock of soil carbon and a substantial natural source of relevant greenhouse gases like CO2 and CH4. While i...
Fep(x, Q2-Fen(x, Q2)的行为和标度性破坏参数
标度性破坏参数 行为 Fep

利用在文章[1]中给出的强子的价夸克分布函数的解析表达式, 我们讨论了电生过程的非单态分量, Fep-Fen, 标度性破坏参数Fep(x, Q2), 以及一些其它的量. 文中也给出了与实验数据的比较.
Cylindrical Piezometer Responses in a Humified Fen Peat
Cylindrical Piezometer Responses Humified Fen Peat
2009/10/26
Most studies of peat hydrology have concentrated on processes below the
watertable where pore water pressures and hydraulic conductivity are measured
using piezometers. While piezometer head recover...
Hydrology of a Patterned Bog-Fen Complex in Southeastern Labrador,Canada
Patterned Bog-Fen Complex Southeastern Labrador
2009/10/26
A 0.05 km2 patterned bog and a 0.29 km2 ribbed fen were compared to determine
the influence of their morphometry on runoff and evapotranspiration.
The bog hydrology was dominated by irregularly loca...
Fluxes and 13C isotopic composition of dissolved carbon and pathways of methanogenesis in a fen soil exposed to experimental drought
Fluxes 13C isotopic composition dissolved carbon pathways methanogenesis
2010/1/18
Peatlands contain a carbon stock of global concern and significantly contribute to the global methane burden. The impact of drought and rewetting on carbon cycling in peatland ecosystems is thus curre...
结构特异性核酸酶FEN-1的功能和结构
结构特异性核酸酶 DNA复制 DNA修复
2008/7/11
FEN-1(flap endo/exonuclease)是一种结构特异性核酸酶，它能识别特定的DNA分叉结构，并切除含有游离5′端的单链核酸. 在DNA复制过程中，FEN-1通过其外切酶、内切酶活力去除了冈崎片段前端RNA引物的最后一个核糖核苷.在DNA修复中，FEN-1以其内切酶活力参与了损伤碱基的修复过程.FEN-1基因含有两个保守区和一个PCNA结合区.
Measurements of hydrocarbon emissions from a boreal fen using the REA technique
Measurements hydrocarbon emissions boreal fen REA technique
2010/1/13
Fluxes of biogenic volatile organic compounds (VOC) and methane were measured above a boreal fen. Vegetation on the fen is dominated by Sphagnum mosses and sedges. A relaxed eddy accumulation (REA) sy...
