Antinociception and VGSC-modulation of BmK IT2 and BmK AS—1. The results from nociceptive flexion reflex and plantar radiation heat showed: BmK IT2 (a depressant insect-selective neurotoixn) and BmK AS-1 (a new-type β-1ike neurotoxin) have significant antinociceptive effects on rat peripheral nerve system. The antinociceptive effects of BmK IT2 on the carrageenan-inflamed rats were significantly stronger than those on the normal rats. Whole-cell patch-clamping showed: Both TTX-S and TTX-R Na〓 currents induced from rat DRG neurons were significantly inhibited by BmK IT2 and BmK AS—1, and BmK IT2 was more sensitive to TTX-R than TTX-S component. All the results suggested: the peripheral antinociception of BmK IT2 and BmK AS—1 might be attributed to the inhibitory effects of them on the TTX-S and TTX-R Na〓 channel located on the peripheral ends of rat DRG neurons with small diameter.

No traveller returns, puzzles the willThan fly to others that we know not of?Thus conscience does make cowards of us all;Is sicklied oer with the pale cast of thought,With this regard their currents turn awry,And lose the name of action.--Soft you now!The fair Ophelia! Nymph, in thy orisons

傻瓜散户们啊，现在我们的市场经过牛市大比例送配，增发，发新股，大小非减持，筹码已经是这个星球最多的市场了，严重的供大与求，聪明人都一个接一个离开了，别相信有人现在就在进场，切记切记啊。

The first control strategy has the disadvantages such as a large amount of computations, inherent pull-out torque, difficulties in realizing the adaptive control and so forth. For the rotor flux-oriented control, changing of load or the rotor speed will result in increased or decreased torque winding currents, which will change the magnetic field distribution in the air gap. Assumption that magnetic field is approximately equal to that generated by torque windings will affect the levitation performances.

分析表明：气隙磁场定向控制中存在最大转矩限制、非线性机械特性，难以实现自适应控制等问题；对转子磁场定向控制而言，当负载或转速变化时，由于转矩控制绕组转矩电流变化将导致气隙磁场发生改变，如果仍以转子磁场近似替代气隙磁场作为悬浮依据，必然影响到悬浮控制性能。

A few more hurricanes like Katrina, a few dramatic floods in the coastal cities of the rich world, perhaps even the shutting down of a part of the world's great conveyor belt of ocean currents, especially if it were the one that warms up western Europe: any of these would catch the attention of policymakers.

如果再多几个象卡特里娜那样的飓风，再多几场富国海滨城市的戏剧性的大洪水，也许甚至是世界海流大传送带的部分停止，特别是西欧变暖：也许这些才能引起政客们的注意。
