Based on 105 Magnetic Cloud (MC) events detected by WIND spacecraft from 1995 to 2007, according to whether the MC collided with the Heliospheric Current Sheet (HCS), the MC events are devided into two types, namely, colliding and non-colliding. The preliminary results are as follows. Firstly, there are 51 MCs which may have collided with the HCS, and that is about 49% of the total incident. Secondly, when a MC collided with the HCS, dynamic interactions tend to inhance in the region between magnetic cloud and heliospheric current sheet, such as appearance of local magnetic field directional discontinuity structures, decreased magnetic field strength, increased proton temperature, irrupt changes of some components of proton velocity, enhancement of ionacoustic waves or Langmuir waves. These phenomena are possibly related to magnetic reconnection in the colliding interaction regions. In case of non-colliding, these characteristics are not evident. Thirdly, in at least 15 cases, the magnetic polarity of the background magnetic fields in front of the magnetic cloud and the one behind the magnetic cloud are opposite, or the reverse point of magnetic polarity was inside the magnetic cloud, which means the magnetic cloud was moving cross the HCS. Lastly, bright fronts and bright cores of MCs have been observed in some events. These very preliminary results are beneficial to understanding the process of interaction between magnetic cloud and the heliospheric current sheet, however further researches are still required.
