The present invention relates to a method for heuristically starting up DC brushless servo electric machine, including the following steps of (1) after powerup of an increment type photoelectric encoder, electrifying a stator winding two by two with identical time interval to generate six-directional stator winding resultant magnetic fields;(2) detecting six different angles rotated by the rotor within identical tiny time interval by the photoelectric encoder;(3) selecting most positive value rotation angle from the six different angles, and determining maximum torque corresponding to the stator winding resultant magnetic field, and implementing servo startup using the maximum torque as constant starting torque;(4) after the zero-point signal of the photoelectric encoder occurring, switching to servo operation with normal constant torsion.

本发明直流无刷伺服电机试探启动方法，采用如下步骤：(1)增量式光电编码器上电后对定子绕组采用相同的时间间隔两两通电，顺序产生六个方向的定子绕组合成磁场；(2)由增量式光电编码器检测出转子在相同的微小时间间隔内分别转过的六个不同的角度；(3)从转子六个不同的角度中选出最大正值的转角，确定相应定子绕组合成磁场对应的最大转矩，并以该最大转矩为恒定启动转矩进行伺服启动；(4)当增量式光电编码器零点信号出现后，切换为正常恒转矩伺服运行。

Cell proliferation and viability were assayed 48h after transfection, and MDA-7 demonstrated selective inhibition of tumor cell growth, inhibitory rates of A549, Hela and HepG2 cell lines were 25%, 20% and 19%, respectively, but had no significant effect on human fetal kidney derived 293 cell line. Hela cell was screened by G418 for 2 weeks after pcDNA3-MDA-7 and monolayer colony was counted, its monolayer colony formation was 30% of cells transfected with pcDNA3. 0 vector. CMV-driven MDA-7 adenovirus vector was constructed. 293 showed no significant apoptosis during adenovirus packaging and the unpurified adenovirus titer was about 1×10〓pfu/ml. Cos 7, A549, Hela, HepG2 and Hep3B cell was infected with Ad-GFP at different MOI.
