Thirdly, in order to improve the learning efficiency and stability of feedforward neural network, a fast learning algorithm for neural networks based on CGM-OC approach is presented. Compared with other learning methods such as BP method, Broyden Flecher Goldfarl Shanno method and Powell method in which the derivative is replaced by the difference quotient etc, simulation results show that the proposed method is an efficient and fast one.

第三，为了提高前馈神经网络权值的学习效率及稳定性，提出一种基于正交校正共轭梯度优化方法的神经网络学习算法，通过与其它学习算法（如：BP算法、变尺度法、用差商近似代替导数的Powell法等）的比较，经仿真试验表明，本算法是一种高效、快速的学习算法。

The boundary value problem for first-order differential equations with a parameter refers to the finite solution condition of equation which includes unknown quantity and its first-order derivative that not only relies on interval value but also relies on the parameter of the equation,which is always settled by fixed point theory or successive approximation method.

含一个参数的一阶微分方程边值问题是指：含有未知量及它的一阶导数的方程的定解条件不仅依赖于在区间端点的取值，而且依赖于方程中的参数。通常它用不动点定理或逐步逼近法来解决。

Using MK- 801 double board computer and digit to anolog interface circuit as hardwar, de-sign and a set of temperature autocortrol system , sassociating with DWK- 702 instrument of tempera-ture fine control, applying to production technique of T1 -superrconductors and making this automa-tize.

采用MK－801双板计算机及其数模接口电路为硬件，设计并制造一套温度自动控制系统，联合DWK－702精密温度控制装置，对T1系超导材料的烧制过程进行自动控制，使这一过程自动化、程序化、并提高了温度控制精度。

In digital mode a cassette file consists of several recorded messages and each click on Record button creates a new message, while in analog mode a cassette file represents one continual rewritable message.

在数字模式1盒档数录得的信息和每一次点击记录按钮创建一个新的讯息，而在模拟模式一卡式档案代表一个不断重写的讯息。

The truth is that, just as in the other imitative arts one imitation is always of one thing, so in poetry the story, as an imitation of action, must represent one action, a complete whole, with its several incidents so closely connected that the transposal or withdrawal of any one of them will disjoin and dislocate the whole.

事实是，正如在其他模仿技艺中人们总是只模仿一个事物，诗歌中也是如此，作为对行为的模仿，故事必须呈现一个行为，一个完整的行为，这一整体由数个事件构成，其相互关联极为紧密，以至其中任何一个事件只要调换了位置或者消失就会使这一整体分离混乱。

After hundreds of years living in space not having to move a muscle, we've devolved to the point of being fat couch potato globs that vaguely resemble the Pillsbury Doughboy.

在太空生活的数百年里，我们一动不动，成天看电视，都退化成了懒散、肥胖的一团，看上去仿佛一个个皮尔斯伯利面团宝宝。

This is also where 10 storey ocean liners dominate the skyline, disgorging thousands of US tourists for one day visits – a symbol of what many see as a downmarket tourist tradition that should be shed.

这里停留着一艘统治地平线的10层远洋客轮，每天运送数千名美国游客，这是许多人所说的低档游客传统的象征，他们认为，这一传统应被放弃。

Each wet tyre is able to drain off of litres of water in a second.

一条 F1雨胎可以在一秒钟内排出数十升积水。

He fights as you sing prick-song, keeps time, distance, and proportion ; Rests me his minim rest, one two, and the third in your bosom : The very butcher of a silk button, a duelist, a duelist ; A gentleman of the very first house , of the first and second cause : Ah, the immortal passado !

他击剑如同按音符唱歌，保持一定的时间、距离和比例。他给你半音符的喘息时间，一、二，数到三，剑进入你的胸膛。他简直是穿着银纽扣礼服的屠夫，一个决斗专家，情场决斗的老手！他是一流出身与一、二流事业的绅士。啊，他那非凡的剑法！

Inflorescence a single, stiff, 2-sided raceme, spikelets arranged edgeways on, alternate in 2 opposite rows, their inner edges sunk in hollows of the tough rachis. Spikelets laterally compressed, florets several to many, uppermost florets reduced, disarticulating below each floret; glumes leathery; lower glume suppressed except in terminal spikelet and there similar to upper; upper glume abaxial, narrow, persistent, shorter than lemmas to as long as spikelet; lemmas membranous to leathery, rounded on back, 5–9-veined, with or without a subterminal awn; palea usually equal to lemma.

花序一单个，硬，2边的总状花序，小穗侧面压扁，小花数枚到多数，在每小花下面退化，脱节的最上部的小花；颖片革质；压抑的更低的颖片除了在顶生的小穗里和那里类似于上面；背面，狭窄，宿存的上面颖片，短于外稃在倍于小穗；外稃膜质到革质，在背面上圆形，5-9－脉，有或没有一芒；内稃通常等于外稃。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
