Other AbstractMagnetic reconnection is considered to be of crucial importance not only to space science but also to magnetically confined fusion,as well as many basic processes in astrophysics and cosmology.In general,except on a closed field line,three-dimensional(3D) magnetic reconnection occurs on the separator connecting magnetic nulls and separatrices,which are determined by the eigenvectors of the magnetic field gradient matrixes of the null pair.Due to the 3D geometric property,the null can only be detected by an at least 42 point measurement so fir uniquely provided by the Cluster mission. Here the authoxs review the recent progresses in applying the Poincare method of magnetic null identification to find cut(1) the in situ evidences of frnr types of nulls (A, B, As and Bs) and their fans and spines; (2) the spatial scale of the spine 3ructure of the null being of the order of local ion inertial length scale, sumestmg that the Hall effect should be important in 3D reamnection dynamics; (3) the in situevidence for the existence cf A2B, B2 As null pairs and the separates lines axnbining the null pairs; and(4) the existence cf a lower hybrid heating and cxcillaticm acceleration in the iimnediate vicin卯of the A2B separator line, which provides a pcxsible mechanism for electron in the remnnedion process. It is the first in situ evidence for axnpl}e 3D raccnnectam geometry and associated dynamics, a crucial step tcavard to establish an observational framework of 3D raconnecticn
