The coring was successfully operated on the winter ice-cover of the lake in 2000 and the pioneer practice of the ""off-the-ice"" coring proves to be very useful and economic for taking quality cores from lakes in northern China.A multidisciplinary investigation has been carried out on core HQH4, one of the three 11-m-long cores. Results from previous investigation include lithostratigraphy, radiocarbon dating, paleoecology of Ostracoda, stable isotopic record of ostracod shells, total nitrogen and organic carbon, C/N ratio, 81 C of organic matter etc.

A novel three-dimensional localization method is proposed. Firstly, the tomato effective centric spots are obtained from the left multi-sensor fusion image and the right multi-sensor fusion image. Then, being looked as symmetries, image pairs other point to point correspondences are searched from two directions by pixel neighbor area correlation values by using the polar line restraint, the unique restraint and the disparity gradient restraint.

Experimentally, multi-pores are observed on leukocyte lysed with 3D electrodes and just single pore with planar electrodes. This is believed to be due to more uniform electric field of 3D electrodes than that of planar electrodes. Intracellular elements are extracted through the membrane as observed by increased intensity of Trypan blue when diluted by saline solution. We also demonstrate the lysing percentages at same flow velocity to explain the performance of 3D electrode is superior to that of planar electrode.

在实验方面，可发现细胞在3D 电极的形况下，是有多个破孔出现，有别於在平面电极的单个破洞，也发现当细胞出现破孔时，经由Trypan blue的辅助观察以及在食盐水稀释情况下，细胞内液是往外流出的，另外由裂解比率的结果，3D电极也是优於平面电极。

Coherent interference can be suppressed by the EMCMVB efficiently. The EMCMVB first gets the modified signal subspace by using the estimated arrival angles of coherent interferers and the eigenstructure of the correlation matrix, and then projects the MCMVB weight vector onto the modified signal subspace.
