Here mainly introduces five natures of the initial value problems, In several aspects summed up as the following : whether there are solutions to the problems, whether the only solution, the existence of solutions interval extent; Initial issues under what conditions have a solution--Cauchy - Piano existence theorem; how the district between the definition of a solution to open up a larger interval up; initial value problems for the sole condition --- Lipschitz conditions; 3、the numerical solution of the initial value problems of Ordinary Differential equations .

在这里主要介绍了初值问题的5个方面的性质，分别在这几个方面中总结了以下内容：初值问题是否有解，解是否惟1，解的存在区间有多大；初值问题在什么条件下有解----柯西-皮亚诺存在定理；怎样把在小区间上有定义的解开拓到较大的区间上去；初值问题解的惟1性条件---李普希茨条件；3：常微分方程初值问题的数值解法。

Britain's death duty goes back further. Taking modern shape in 1894, it can be traced back to 1694 when probate duty was introduced. Since 1986 it has confusingly been called inheritance tax although it is nothing of the sort. Like America's estate duty it remains a levy on the amount left by the deceased and does not tax what individual beneficiaries receive.

英国的遗产税的历史更加久远，其现代模型成形于1894年，可以追溯到1694年征收的遗嘱税，从1986年开始，虽然与继承税没有什么相似之处，但大家仍常将二者搞混，比如说美国的不动产税，征收所有遗产中的一部分作为抵押品，而不是对接收遗产的个人受益者征税。

ET tube insertion procedures were performed on 59 pediatric patients aged newborn to 17 years (33 boys) due to cardiopulmonary arrest or impending respiratory failure. Ultrasound images were taken before and after the procedure in two-dimensional and time-sector modes using a portable ultrasonic machine. The subxiphoid window at the mid-upper abdominal — just beneath the xiphoid process and the lower margin of the liver — was used most often, with a wide transducer sector angle (90 degrees) for bilateral scanning of the diaphragm.

这项试验对59位从新生儿到17岁（33位男童）的小儿科病患进行插管，插管的原因是因为心肺衰竭或是严重的呼吸衰竭；在插管前与后使用可携带式超音波机器进行二度空间与时间象限的超音波显影；最常使用中上腹的剑突影像，就在剑突与肝脏下下缘部份的影像，与以宽的转换区间角度（90度）作横隔膜双侧扫描。

This group includes the high school dropout and professional car racer Han Han, 25, who derides China's inefficient educational system in his novels and regularly insults older, more established artists on his blog, and Zhang Yueran, 26, whose novel "Daffodils Took Carp and Went Away" features a bulimic girl who falls in love with her stepfather, is mistreated by her mother and is sent off to boarding school.

这个写作群成员包括高中辍学现成为专业赛车手的25岁的韩寒，他在小说中讽刺了中国低效的教育体制，并常在博客中攻击较他年长的已成名作家。还有26岁的张悦然，其小说《水仙已乘鲤鱼去》塑造了一个爱上继父的患暴食症的女孩，她后被虐待她的母亲送到了寄宿学校。

On questions of social morality, of duty to others, the opinion of the public, that is, of an overruling majority, though often wrong, is likely to be still oftener right; because on such questions they are only required to judge of their own interests; of the manner in which some mode of conduct, if allowed to be practised, would affect themselves.

在社会道德的问题上，在对他人的义务的问题上，公众的意见也即压制的多数的意见虽然常常会错，大概更常常会是对的；因为在这类问题上他们只需要判断他们自己的利害，只需要判断某种行为如任其实行出来将会怎样影响到自己。

For the nobler plants are valued for the fruit they bear at last in the air and light, far from the ground, and are not treated like the humbler esculents, which, though they may be biennials, are cultivated only till they have perfected their root, and often cut down at top for this purpose, so that most would not know them in their flowering season.

因为那些更高贵的植物的价值是由远离地面的、最后在空气和日光中结成的果实来评定的，而不是像对待那低卑蔬菜的那样。蔬菜就算是两年生的植物，那也只是被培植到生好根以后，而且常被摘去顶枝，使得许多人在开花的季节都认不得它们。

Point of the Island, I was perfectly confounded and amaz'd; nor is it possible for me to express the Horror of my Mind, at seeing the Shore spread with Skulls, Hands, Feet, and other Bones of humane Bodies; and particularly I observ'd a Place where there had been a Fire made, and a Circle dug in the Earth, like a Cockpit, where it is suppos'd the Savage Wretches had sat down to their inhumane Feastings upon the Bodies of their Fellow-Creatures.

好久好久，我忘记了自身的危险。想到这种极端残忍可怕的行为，想到人性竟然堕落到如此地步，我忘记了自己的恐惧。吃人的事我以前虽然也经常听人说起过，可今天才第一次亲眼看到吃人留下的现常我转过脸去，不忍再看这可怕的景象。

Yosemite National Park,one of the first wilderness parks in the United States,is best known for its waterfalls,but you can also find deep valleys,grand meadows,ancient giant sequoias,and much more in it.Yosemite isn't known for its autumn colors,because most of the trees are evergreens.However,you can find some colorsin Yosemite in mid to late October and even into early November.

约塞米蒂国家公园，公园的第一旷野，在美国是最闻名的瀑布，但你也可以找到深谷，大草场、古代巨人红杉树时，更多的是约塞米蒂不是闻名的秋天的颜色，因为大部分的树木常绿然而，你可以找到一些colorsin约塞米蒂在中期十月下旬，甚至到十一月初。

Sophia Loren was right in front of me - she's a foot taller than I am, not counting the poofy hair. She walked elegant ly, like a giraffe on the African savannah, holding the flag on her shoulder. I jogged behind ---- on my tiptoes, holding the flag on my extended arm, so that my head was actually under the damn flag. All the cameras were, of course, on Sophia. That was fortunate for me, because in most press photos I appear too, although often between Sophia's legs. A place where most men would love to be. Applause

罗兰就站在我前面，比我高一个头如果蓬松头不计算在内的话她步伐优雅，就像是非洲摹上的长颈鹿将旗子一端扛在肩上，我则在后面小跑着掂着脚，举高手才勉强够到旗子因此，我的头实际上是在那旗子下面所有的镜头当然是索菲亚我还算幸运，因为后来登出的照片中，都有我的存在，虽然常是在索菲亚的双腿间那可是大多数男人梦寐以求的地方。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
