And the frequency of TCR V��Ⅲ in CP and CR patients is markedly lower than that from healthy adults（P=0.013,P=0.043）. The most frequency used V��Ⅱsubfamily of clonally expanded T-cells were identified in both CP and CR patients.

CP和CR期病人TCR VγⅢ的表达率明显低于健康对照组（2.9±0.32）（P=0.013，P=0.043），基因扫描显示CML-CP 和CML-CR出现克隆模式的改变主要集中在TCR VγⅡ亚家族。

The influence of V and Cr content on the hydrogen storage properties of TiVCr based alloys was investigated. The desorbing plateau pressure of the alloys decreased slightly and the capacity of absorption and desorption increased slightly with increasing V content.

为此研究了钛钒铬基合金中V、Cr含量对贮氢性能的影响，结果表明：随着金属元素V含量的增加，合金的放氢平台压力略有降低和吸放氢量略有增大。

Methods: Electrets Teflon PTFE,±300 V,±1 000 V were used to treat 3T3 cells for 24, 48 and 72 h. Then the influences of electrets on cell cycle and surface charge of 3T3 cells were studied by flow cytometry and electrophoresis, respectively.
