闭路

Our company is a specialty deditcated truck manufactures,our company has own expot right ,and our water sprinkler ,road sweeper sewage suction truck,high-altitude truck ,aerial truck and vans are export to foreign countries ,and our dump trucks also have a large number of foriengn market.which dose not means that business would have been so good to do you .we are still faced with severs knock,The world is such that you never rest on its laurel,in this world you are not progress ,that means it is a biggest step backword,you may bot be saring by leaps and bounds.but you must be persistent sffers,even small steps to move,as long as you are moving ,you have hope,as long as you still has not been extinguished,you have the right to breed,this is the reality in this world.i have gone through the kind of look at the age of fairy tales,and i have already through the kind of the passion for survival alone love,aithough i still have in mind dream,the splendor of breathtaking beauty of dream,but i know that is the real dream that is close our eyes at night,and i know whick is my future that i must begging for it..

我所在的公司是个特种专用卡车制造厂家，自己有自行出口权，我们的环卫洒水车，环卫扫路车，环卫吸污车，环卫高空清洗车，高空作业车，厢式车都是远销国外的优良产品，同时我们的自卸车也在国外占据着大量市场，这并不代表生意就这么好做哟，我们仍然面临这剧烈的淘汰赛，这个世界就是这样，你永远不可以坐吃山空，在这个世界中，不进步就是最大的退步，你可以不是突飞猛进的高升，但是你一定要坚持不懈的努力，哪怕是一小步一小步的移动，只要你还在动，你就有希望，只要你还没有泯灭，你就有权利滋生，这就是现实中的世界，我早已经过了那种看童话故事傻笑的年龄了，我也早已经过了那种只靠激情度日的年华，我虽然心中仍然有梦，美的让人窒息的绚丽的梦，但是我现在却知道那只是真正的梦，是我只能在夜里闭着眼睛才可以实现的梦，那些我应该在阳光下昂起头来努力实现的才叫做未来。

There is n strong association of PFO with paradoxical embolism and ischemic cerebral infarction, and reports on patients with PFO-related cryptogenic stroke after coronary artery bypass grafting and various surgical cases of heart or lung are being increasingly published in recent years.

近年来的研究发现，卵圆孔未闭的存在与反常栓塞、缺血性脑卒中的发生密切相关，与冠状动脉旁路移植术及各种心、肺手术后不明原因的卒中或猝死相关的报道日益增多。

At the same time,we have tried the precess for the preparation of 3-exomethylene cepham sulfoxide ester by the improved ring-expanding method over Kukolja, in which the different acid scavengers are employed in the presence of tolune, NCP and stannic chloride.

同时尝试了改进的Kukolja扩环法合成3—环外亚甲基头孢亚砜酯。以甲苯为溶剂，NCP为卤化试剂，无水SnCl_4为路易斯酸，通过选用了不同的酸清除剂，以制备闭环产物。

Occasionally he closes his eyes...just for a second...to drift into a daydream...as he trudges down the straight and easy road to the county town of Malong in Yunnan.

偶尔，他闭上双眼……只有一秒钟……沉浸在白日梦中……此时他正跋涉在通往云南马龙县县城的路上，这条路很直也很好走。

By the balance of communication link power, SNR balance guidelines and BER balance, under the base to meet the requirements of systems and not affecting thequality of call. Finally, the open-loop/closed-loop variable step length reverse power control is introduced, its principle is under the original open-loop power control to select suitable power control step by the new power control bit, and achieves a balanced system fastest and most effective.Keywords: Step, Power-control, Brethren interference, Proximity effect

依据通信链路的功率平衡准则、信噪比平衡准则和误码率平衡准则，在满足系统要求和不影响通话质量的基础上，最后提出了开环/闭环可变步长的反向功率控制，其原理是在原有的开环功率控制的基础上，依据新的功率控制比特，来选取合适的功率控制步长，以最快、最有效的方法使系统达到平衡。

By applying higher scale factors to downlink channel responses corresponding to reliable FBI detection, better closed transmit diversity performance during soft handovers may be achieved.

通过将较高的比例因子应用到与可靠的反馈信息检测相对应的下行链路信道响应，可在软切换期间实现更好的闭环发送分集性能。

In our most trivial walks, we are constantly,though unconsciously, steering like pilots by certain well-known beacons and headlands, and if we go beyond our usual course we still carry in our minds the bearing of some neighboring cape; and not till we are completely lost, or turned round —— for a man needs only to be turned round once with his eyes shut in this world to be lost—— do we appreciate the vastness and strangeness of nature.

在我们的日常散步中，我们经常地，虽然是不知不觉地，像领港的人一样，依据着某某灯塔，或依据某某海角，向前行进，如果我们不在走惯的航线上，我们依然在脑中有着邻近的一些海角的印象；除非我们完全迷了路，或者转了一次身，在森林中你只要闭上眼睛，转一次身，你就迷路了，——到那时候，我们才发现了大自然的浩瀚与奇异。

Without the wonderful element of doubt, the doorway through which truth passes would be tightly shut, impervious to the most strenuous poundings of a thousand Lucifers.

毫无疑问，通往真理的大门会紧闭，即使最强大的路西法也无法穿透

It is safe, convenient and feasible that Medtronic extracorporeal membrane oxygenator package is modified to common CPB and closed circulation channel for operation on heart, but must be pay attention to prevent thromboses at shunt adaptor and avoid the air getting into tubing during switching process.

应用Medtronic ECMO套包改装的常规CPB与闭式ECC相互转换管路临床应用方便、安全、有效，但要注意防止在旁路接头处形成血栓，防止转换过程中管道内进气。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
