变大

With the demand of quick respond and precision for missile flight in terminal guidance, an adaptive nonlinear controller is designed that guarantees tracking performance when the uncertain parameters vary within stability bound. In order to achieve asymptotic tracking, adaptation is introduced to enhance closed-loop robustness, while mach number and mass changes with 35%.

文中根据导弹响应快和精度高的基本要求，在导弹变向跟踪接近目标时，对导弹制导控制过程中的控制方法进行研究和数学推导，提出了一种导弹末制导的自适应控制方法，该方法提高了导弹马赫数和质量在较大范围（35%）内变化时系统的响应精度和稳定性。

Results showed endothelialcells inoculated by shimen virulent strain of CSFV have no obvious change after 12h,24h;At36h,cells become be elongate and appearanced defluvium;At 48h,a few of cells started tobecome round and intercellular space become auxesis;At 72h, intercellular space becomemore auxesis, defluvium of cells was acute.

结果表明，血管内皮细胞于接种 CSFV 石门株后 12h，24h 无明显变化，至 36h 时，细胞开始拉长，个别细胞开始脱落；至 48h 时，部分细胞变圆，脱落，细胞间隙增大；至 72h，细胞拉长呈长梭状，细胞间隙很大，细胞脱落严重。3 个对照组的细胞均未出现明显变化。

Biological Qualcomm reported that since the world recognized the success of the most promising AIDS vaccine trial has been declared a failure, the date of successful AIDS vaccine seems to have become the foreseeable future, the Nobel Medicine Prize, the world's leading AIDS expert David Baldi Professor Moreton speech, claiming that the complexity of HIV based on the variability in the 25 years of human AIDS vaccine can not be found,"and most likely never find such a vaccine."

生物通报道，自从被世界公认最有希望获得成功的艾滋病疫苗试验宣布失败以来，艾滋病疫苗成功之日似乎变得遥遥无期，诺贝尔医学奖得主、世界著名艾滋病研究专家大卫·巴尔迪摩教授发表演说，声称基于艾滋病病毒复杂的变异性，人类在25 年内不可能找到艾滋病疫苗，"并且很有可能永远也找不到这种疫苗。"

We want to emphasize three points:(1) While we expect our super-cat business to produce satisfactory results over, say, a decade, we're sure it will produce absolutely terrible results in at least an occasional year;(2) Our expectations can be based on little more than subjective judgments - for this kind of insurance, historical loss data are of very limited value to us as we decide what rates to charge today; and (3) Though we expect to write significant quantities of super-cat business, we will do so only at prices we believe to be commensurate with risk.

我们有三点必须要强调(1)我们预期霹雳猫的业务长期来讲，假设以 10 年为期，应该可以获得令人满意的结果，当然我们也知道在这其中的某些年度成绩可能会很惨(2)我们这样的预期并非是基于客观的判断，对于这样的保险业务，历史的资料对于我们在做订价决策时并没有太大的参考价值(3)虽然我们准备签下大量的霹雳猫保单，但有一个很重要的前提那就是价格必须要能够与所承担的风险相当，所以若我们的竞争对手变得乐观积极，那幺我们的量就会马上减少，事实上过去几年市场价格有点低的离谱，这使得大部分的参与者都被用担架抬离场。

Sometimes the neighbour's pigeons land on my windowledge Cooing softly Where the great poplar at the window has somehow grown beyond the fourth-floor roof They skim round its crown and back The sunlight on their fluffy feathers Alive day by day I keep coming indoors empty-handed And throwing book and jacket on the bed As the days hurry by I can bring scarcely anything home Even after days away Only you remain and the little room Living day by day We have grown used By an unspoken pact to the room's breadth A pair of pigeons cooing softly on the windowledge Which at many instants belong to us Day by day Dust that falls on book spines gradually yellows Perhaps it is otherwise That life, if it does, provides I know that the unwitting request is not excessive And that summer turns to autumn Perhaps fallen leaves will swirl after a night of rain It does not mean a return to green shade deep in sunlight A house-cleaning when leisure affords Feelings may come on latent even as Irrelevancies are spoken softly The instant when a first trembling on the lips teaches you happiness Lasts till the end of life A request always voiced unwittingly

有时候，邻家的鸽子落在我的窗台上咕咕地轻啼窗口的大杨树不知不觉间已高过了四层楼的屋顶它们轻绕那些树冠又飞回来阳光在蓬松的羽毛上那么温柔生命日复一日我往往空着手从街上回来把书和上衣掷在床上日子过得匆匆忙忙我时常不能带回来什么即使离家数日只留下你和这小小的屋子生活日复一日面对无声无息的默契我们已习惯了彼此间的宽容一对鸽子在窗台上咕咕地轻啼他们在许多瞬间属于我们日复一日灰尘落在书脊上渐渐变黄如果生活时时在给予那也许是另一回事我知道，那无意间提出的请求并不过份我知道，夏日正转向秋天也许一场夜雨过后就会落叶纷飞不是说再回到阳光下幽深的绿荫日子需要闲遐的时候把家收拾干净，即使轻声述说些无关紧要的事情感也会在其间潜潜走过当唇际间最初的战栗使你感知了幸福这一瞬已延伸到了生命的尽头而那些请求都是无意间说出的
