The definitions and properties of PGOPO are given, a various operational rules of the operator have been set up in a systematic way, the convergence of approximate solutions has been discussed. After introducing PGOPO and discussing its main properties and operational rules, a systematic methodology for solving various control problems via PGOPO has been developed.

The definition and stability criterion of resonant operating points in a CPT system have been described. A Poincarémapping model has been built up and its Jacobian matrix has been derived with the implicit function derivative rule and chain rule. Then the stability of the fixed points can be determined according to the eigenvalues of the the Jacobian matrix. It has been used to study an example push-pull CPT system with three resonant operating points.

I observ'd, that the two who swam, were yet more than twice as long swimming over the Creek, as the Fellow was, that fled from them: It came now very warmly upon my Thoughts, and indeed irresistibly, that now was my Time to get me a Servant, and perhaps a Companion, or Assistant; and that I was call'd plainly by Providence to save this poor Creature's Life; I immediately run down the Ladders with all possible Expedition, fetches my two Guns, for they were both but at the Foot of the Ladders, as I observ'd above; and getting up again, with the same haste, to the Top of the Hill, I cross'd toward the Sea; and having a very short Cut, and all down Hill, clapp'd my self in the way, between the Pursuers, and the Pursu'd; hallowing aloud to him that fled, who looking back, was at first perhaps as much frighted at me, as at them; but I beckon'd with my Hand to him, to come back; and in the mean time, I slowly advanc'd towards the two that follow'd; then rushing at once upon the foremost, I knock'd him down with the Stock of my Piece I was loath to fire, because 1 would not have the rest hear; though at that distance, it would not have been easily heard, and being out of Sight of the Smoke too, they wou'd not have easily known what to make of it: Having knock'd this Fellow down, the other who pursu'd with him stopp'd, as if he had been frighted; and I advanc'd a-pace towards him; but as I came nearer, I perceiv'd presently, he had a Bow and Arrow, and was fitting it to shoot at me; so I was then necessitated to shoot at him first, which I did, and kill'd him at the first Shoot; the poor Savage who fled, but had stopp'd; though he saw both his Enemies fallen, and kill'd, as he thought; yet was so frighted with the Fire, and Noise of my Piece, that he stood Stock still, and neither came forward or went backward, tho' he seem'd rather enclin'd to fly still, than to come on; I hollow'd again to him, and made Signs to come forward, which he easily understood, and came a little way, then stopp'd again, and then a little further, and stopp'd again, and I cou'd then perceive that he stood trembling, as if he had been taken Prisoner, and had just been to be kill'd, as his two Enemies were; I beckon'd him again to come to me, and gave him all the Signs of Encouragement that I could think of, and he came nearer and nearer, kneeling down every Ten or Twelve steps in token of acknowledgement for my saving his Life: I smil'd at him, and look'd pleasantly, and beckon'd to him to come still nearer; at length he came close to me, and then he kneel'd down again, kiss'd the Ground, and laid his Head upon the Ground, and taking me by the Foot, set my Foot upon his Head; this it seems was in token of swearing to be my Slave for ever; I took him up, and made much of him, and encourag'd him all I could.

这时候，我脑子里突然产生一个强烈的、不可抗拒的欲望：我要找个仆人，现在正是时候；说不定我还能找到一个侣伴，一个帮手哩。这明明是上天召唤我救救这个可怜虫的命呢！我立即跑下梯子，拿起我的两支枪--前面我已提到，这两支枪就放在梯子脚下。然后，又迅速爬上梯子，翻过山顶，向海边跑去。我抄了一条近路，跑下山去，插身在追踪者和逃跑者之间。我向那逃跑的野人大声呼唤。他回头望了望，起初仿佛对我也很害怕，其程度不亚于害怕追赶他的野人。但我用手势召唤他过来，同时慢慢向后面追上来的两个野人迎上去。等他俩走近时，我一下子冲到前面的一个野人跟前，用枪杆子把他打倒在地。我不想开枪，怕枪声让其余的野人听见。其实距离这么远，枪声是很难听到的；即使隐隐约约听到了，他们也看不见硝烟，所以肯定会弄不清是怎么回事。第一个野人被我打倒之后，同他一起追来的那个野人就停住了脚步，仿佛吓住了。于是我又急步向他迎上去。当我快走近他时，见他手里拿起弓箭，准备拉弓向我放箭。我不得不先向他开枪，一枪就把他打死了。那逃跑的野人这时也停住了脚步。这可怜的家伙虽然亲眼见到他的两个敌人都已经倒下，并且在他看来已必死无疑，但却给我的枪声和火光吓坏了。他站在那里，呆若木鸡，既不进也不退，看样子他很想逃跑而不敢走近我。我向他大声招呼，做手势叫他过来。他明白了我的意思，向前走几步停停，又走几步又停停。这时，我看到他站在那里，混身发抖。他以为自己成了我的俘虏，也将像他的两个敌人那样被杀死。我又向他招招手，叫他靠近我，并做出种种手势叫他不要害怕。他这才慢慢向前走，每走一二十步便跪一下，好像是感谢我救了他的命。我向他微笑，作出和蔼可亲的样子，并一再用手招呼他，叫他再靠近一点。最后，他走到我跟前，再次跪下，吻着地面，又把头贴在地上，把我的一只脚放到他的头上，好像在宣誓愿终身做我的奴隶。我把他扶起来，对他十分和气，并千方百计叫他不要害怕。但事情还没有完。

It is the change that virtual technology gives birth to a great influence on the human's cognitive activities. First of all, virtual technology has caused obvious change of cognitive relation between subject and object, which includes the change of interaction between subject and object, digitization of cognitive resonance and scene of cognitive model, etc. secondly, virtual technology has improved the subject's cognitive ability and level: the ability of esthesia of the subject has been strengthened, the change of the cognitive structure and the way to obtain information of the subject has been caused and the regulation and control ability of the subject has been improved by virtual technology. Initiative and creativity has been highlighted in the cognitive activity. Lastly, virtual technology has expanded subject's cognitive field, that is to say it has expanded the cognitive space of the subject, and enriched the cognitive source of the subject The appearance of virtual technology leads to great changes of mankind's practices.

正是这种转向使得虚拟技术对于人类的认识活动产生了重大影响：首先，虚拟技术导致了主客体之间的认识关系发生明显的变化，主要包括主客体作用的方式的变化、认识中介的数字化以及认知模型的情景化等；虚拟技术提高了主体认识能力和水平：虚拟技术增强了主体的感知能力，引起了主体认识结构的变化，认识主体获取信息的方式发生了变革，提高了主体对认识活动的调控能力，张扬了主体在认识活动中的能动性与创造性；虚拟技术拓展了主体的认识领域，即它扩展了主体的认识空间、丰富了主体的认识来源。

But the black kitten had been finished with earlier in the afternoon, and ao, while Alice was sitting curled up in a corner of the gradt armchair, half talking to herself and half asleep, the kitten had been hacing a grand game of romps with the ball of worsted Alice had been trying to wind up, and had been rolling it up and down till it had all come undone again; and there it was, spread over the hearth-rug, all knots and tangles, with the kitten running after its own tail in the middle.

但是黑猫下午就洗完了，所以，当Alice蜷缩在大扶手椅里半梦半醒的自言自语时，小猫已经在和Alice刚才想卷好的毛线球玩了，而且不停地旋转直到它变回没有缠之前的样子；当小猫在中央追着自己的尾巴跑时，毛线球被拽到灶台旁边，所有的结都缠绕起来。

Accordingly, the sowing time of sesame has been postponed. Unlike cotton and peanuts that their price has been declined from the high point of last year to lower than the price level of 2007, the price level of sesame has retained relatively high and stable. So the farmers' enthusiasm of producing sesame has been increased, and the planted area has been enlarged comparing with last year.

由于08产季国产芝麻的价格不仅秉承了07产季的高价格水平而且在整个产季里表现的也相对比较稳定，而棉花和花生的价格自从去年高位下跌以来，期间虽有所反弹，但总体依然低于07产季的价格水平，因而使得农民今年种植芝麻的积极性有所提高，种植面积和去年相比也有所扩大。
