An ice-core record of hydrogen reveals that atmospheric levels vary in response to climate change and have increased drastically owing to human activity since the pre-industrial era. The apparent sensitivity of hydrogen cycling to environmental conditions should be considered when projecting the consequences of rising anthropogenic hydrogen emissions in a warming climate.

Recall that a barycentric coordinate system is given with respect to a -dimensional simplex, where is no larger than the dimensional space. Given a set of scattered points, it’s possible to create a tessellation of the space by forming simplices from the points, such that any input point that lies within the convex hull of the scattered set can be expressed in terms of the enclosing simplex and its corresponding barycentric coordinates2. This can be understood as a kind of triangulated irregular network (TIN).。safew官方版本下载是该领域的重要参考
