We discuss asymptotically best linear unbiased estimators of the Logistic population based on selected order statistics and give the formula of computing the ABLUE, the variance and the covariance of the ABLUE in limit, and properties of the ABLUE, and so on. We give the optimum chosen of spacing which is the ABLUE with maximum asymptotic relative efficiency based on complete sample when selected order statistics number is less than 10, and obtain its maximum asymptotic relative efficiency.

The results indicate that the tailrace tunnel has a good effect on air cooling and dehumidification in summer, and that the parameters of outlet air in the tailrace tunnel are mainly influenced by the temperature of tail water rather than by the parameters of outdoor air and the terminal air parame...

测试结果表明，夏季运行时无压尾水洞对引入空气有良好的降温除湿效果；在无压尾水洞足够长的条件下，尾水洞末端引风参数主要受尾水温度的影响，而受室外空气参数的影响很小，尾水洞出口空气接近对应尾水温度的饱和状态。

METHODS: Human amnion membrane derived mesenchymal stem cells were sterilely isolated and cultured. The third passages of cells (1×109/L)(0.5 mL) were transplanted by tail venous pathway to mice. Mice in the control group were injected with an equal volume of saline, whereas mice in the normal group were left intact.

无菌条件下体外分离培养人羊膜间充质干细胞，传至第3代将细胞浓度调整为1×109 L-1，经尾静脉注入0.5 mL至细胞移植组小鼠体内；对照组经尾静脉注入同体积的生理盐水；正常组小鼠不给予任何干预措施。

Thus, a decoupling chamber pressure control system was designed and installed at the end of the tailpipe of a valveless self-excited pulse combustor. The relative pressure in the decoupling chamber was controlled from about -10 kPa to 10kPa through a blower, and the influence of pressure variation on the heat transfer in tailpipe was investigated.
