凹地

Firstly, a new quasi convex-concave extension definition is introduced to study general constrained optimization problem, which is much approximate function's shape than the interval extension.

首先，对一般约束优化问题，引入一新的概念，即拟凸-凹扩张，它比区间扩张能更好地逼近函数的形状。

Experiments show that, in applying the correct mold structure and appropriate process conditions, when the temperature at 350 ° C billets around Rafah Deep Mold temperature at 350 ° C and about good lubrication circumstances, can be successful in stamping on the crank press to produce magnesium phone alloy shell.

实验表明，在应用正确的模具结构和适当的工艺条件下，当坯料温度在350℃左右，拉深凹模温度在350℃左右和良好润滑情况下，能够成功地在曲柄压力机上冲压生产出镁合金手机外壳。用英文翻译一下哦！！！！！！！！！谢谢！！！！！！！！

The very armchairs, which were as wide as beds, and the sofas, which were as deep as alcoves, invited to slumber oblivious of the flight of time and to tender whispers in shadowy corners.

那些宽大得像床的扶手椅，深得像凹室的长沙发足以引人昏昏欲睡，把时间置之脑后，诱人坐在暗淡的角落里，窃窃私语，笑吟吟地倾吐衷肠。

Areoles spaced far apart in notches along wings or angles.

小窠在翅或角上的凹缺上相隔较远地分布。

Based on the ring-shaped laser-diode array side-pumped Nd:YLF high gain amplifier and the conventional plan-concave resonator, a simple structure single-longitudinal-mode single-pulse Q-switched oscillator is demonstrated by taking advantages of mode-selecting property of passive Q-switches (Cr4+:YAG crystal) and etalons (formed by two end of uncoated Nd:YLF rod).

以激光二极管环形阵列侧面抽运Nd：YLF棒高增益放大器模块为基础，在经典的平凹驻波腔中加入一片Cr4+：YAG晶体作为被动Q开关，利用被动Q开关本身所具有的振荡选模功能以及两端不镀膜的Nd：YLF棒所具有的标准具效应，简便地实现了稳定的单脉冲、单纵模调Q输出。

Perhaps this is one of the components of the magic induced by these images made out of interlocking hemispheres and events, that they are cut out of one and the same wood block, from whose hatchings and notches alone their ethereal identity is drawn.

仅仅只是一块木板，仅仅只是凹痕和阴影，却能将错综复杂的故事和&犹抱琵琶半遮面&的形象完整地刻画出来，或许这就是法兰卡版画作品的神奇之所在。

The dents on the sides of the headrests from where Joe had constantly leaned on the seats....

在靠头之物的边上凹痕从乔不变地已经倚靠座位哪里。。。。

He showed me how to gig for frogs and fish, how to find water collected overnight in the hollow of fallen leaves, to distinguish edible mush-rooms from deadly toadstools, and dozens of other survival tricks.

伊格尔是队伍的领袖，也最为年长，他不厌其烦地解说丛林法则，给我演示如何捕捉青蛙和鱼，如何从落叶的凹处采集露水，如何区分可食用的蘑菇和致命的毒菌，以及其他许多生存技巧。

I sometimes dream of a larger and more populous house, standing in a golden age, of enduring materials, and without gingerbread work, which shall still consist of only one room, a vast, rude,substantial, primitive hall, without ceiling or plastering, with bare rafters and purlins supporting a sort of lower heaven over one's head —— useful to keep off rain and snow, where the king and queen posts stand out to receive your homage, when you have done reverence to the prostrate Saturn of an older dynasty on stepping over the sill; a cavernous house, wherein you must reach up a torch upon a pole to see the roof; where some may live in the fireplace,some in the recess of a window, and some on settles, some at one end of the hall, some at another, and some aloft on rafters with the spiders, if they choose; a house which you have got into when you have opened the outside door, and the ceremony is over; where the weary traveller may wash, and eat, and converse, and sleep, without further journey; such a shelter as you would be glad to reach in a tempestuous night, containing all the essentials of a house, and nothing for house-keeping; where you can see all the treasures of the house at one view, and everything hangs upon its peg, that a man should use; at once kitchen, pantry, parlor, chamber, storehouse,and garret; where you can see so necessary a thing, as a barrel or a ladder, so convenient a thing as a cupboard, and hear the pot boil,and pay your respects to the fire that cooks your dinner, and the oven that bakes your bread, and the necessary furniture and utensils are the chief ornaments; where the washing is not put out, nor the fire, nor the mistress, and perhaps you are sometimes requested to move from off the trap-door, when the cook would descend into the cellar, and so learn whether the ground is solid or hollow beneath you without stamping.

我有时梦见了一座较大的容得很多人的房屋，矗立在神话中的黄金时代中，材料耐用持久，屋顶上也没有华而不实的装饰，可是它只包括一个房间，一个阔大、简朴、实用而具有原始风味的厅堂，没有天花板没有灰浆，只有光光的椽木和桁条，支撑着头顶上的较低的天，——却尽足以抵御雨雪了，在那里，在你进门向一个古代的俯卧的农神致敬之后，你看到衍架中柱和双柱架在接受你的致敬；一个空洞洞的房间，你必须把火炬装在一根长竿顶端方能看到屋顶，而在那里，有人可以住在炉边，有人可以往在窗口凹处，有人在高背长椅上，有人在大厅一端，有人在另一端，有人，如果他们中意，可以和蜘蛛一起住在椽木上：这屋子，你一打开大门就到了里边，不必再拘泥形迹；在那里，疲倦的旅客可以洗尘、吃喝、谈天、睡觉，不须继续旅行，正是在暴风雨之夜你愿意到达的一间房屋，一切应有尽有，又无管理家务之烦；在那里，你一眼可以望尽屋中一切财富，而凡是人所需要的都挂在木钉上；同时是厨房，伙食房，客厅，卧室，栈房和阁楼；在那里你可以看见木桶和梯子之类的有用的东西和碗橱之类的便利的设备，你听到壶里的水沸腾了，你能向煮你的饭菜的火焰和焙你的面包的炉子致敬，而必需的家具与用具是主要的装饰品；在那里，洗涤物不必晒在外面，炉火不熄，女主人也不会生气，也许有时要你移动一下，让厨子从地板门里走下地窖去，而你不用蹬脚就可以知道你的脚下是虚是实。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
