During the beginning （about 3-5 seconds） of operating "Compress" key for oil cylinder handspike to move downwards, push the trash feeding door or pull the main door, hydraulic oil cylinder handspike stops immediately,"Compress" light goes out, discontinuous ringing arises, and the screen shows "Breakdown"; reset the door, the ringing stops, and the screen shows "Compress"; after hydraulic oil cylinder handspike automatically returns to the original place, indicator light "Compress" goes out.

在操作"压缩"键使油缸推杆向下运动后的最初时间内（约3-5秒），推动垃圾投入门或拉开大门，液压油缸推杆立即停止运动，"压缩"显示灯灭，产生缓慢间歇讯响，显示"故障"；门恢复后，停止讯响，显示"压缩"，液压油缸的推杆自动回到原始位置后，指示灯"压缩"灭。

We will continue teaching Lindy / Swing with 8-count steps like Lindy Circle and Swing-out on this and next Saturday. We will add more steps of inside turn, outside turn, swivels, chicken walks, kick backs, tuck double turn, and American spin, etc.

我们在学习 Lindy Circle 和 Swing-Out 的基础上要添加各式样的8拍舞步-如向内侧和外侧的旋转，摇摆扭臀，鸡脚走步，向后踢腿，侧向垫步加两周旋转，美式旋转等动作。

For the quiet and regularity transformation, people at last found that even themselves, every one's actions either forward, backward, leftwards or rightwards, all serve for the great transformation and work all for the specific and fast coming of the great transformation.

对于这场本身是平静的、规律性的变革，最后人们也会惊奇地发现，甚至自己——每一个人的每一个活动，不管是向前还是向后，向左还是向右，都早已在为这一巨变服务，都在为这一巨变更为明确、更快到来而工作。

He was in many ways a primitivist: he saw little reason for optimism in modern society, and looked nostalgically backwards towards the days of pastoral, agricultural England.

他在许多方面是一个primitivist ：他认为没有理由乐观，在现代社会，并期待怀念向后向天的畜牧，农业英格兰。

However, in more general case, such as in vector/martix-valued case, it should be noted that it appear diffcult to find recurrence relations similar to the famous three-term recurrence relation which can be used to derive surprisingly good results in the convergence theory for scalar continued fractions.

在这一章，我们把第二章的向后三项递推算法推广到向量值情形。

The customer after being on commission can enter commercial building and have a look around the goods and put the goods chosen into the electronic shopping cart , After finish choosing, can reselect the goods selected again , send the order information to the electronic corresponding shop of commercial building through the network after acting as full confirmation, Shop receive order at customer and goods information send information to, Then the shop sends the goods to customer's home, and to the clear fund of the bank at the same time.

被授权后的顾客可以进入商厦浏览商品并把选中的商品放进电子购物车中，当选择完毕后，可以再重新选择所挑选的商品，当完全确认后把订货信息通过网络送到电子商厦所对应的商店，商店接到订货信息后将顾客和商品信息送到银行认证中心进行电子签名认证并登记，然后商店将商品送到顾客家中，并同时向银行清款。

To analyze the pseudo phenomena caused by migration velocity error, the paper firstly studied the depth error between post-stack migration and prestack migration caused by same velocity error, and found the depth error was only relative to velocity error and had no direct matter with methods of depth migration (post-stack migration or prestack migration). Then the paper did numerical simulation of a complex lenticular body model with wave-equation modeling and migration, and found that the velocity error could not only induce depth error, but also could change the modality of construction and the event of subjacent layers. Furthermore, it could change the frequency of reflective event. They are the pseudo phenomena caused by migration.

从分析偏移速度误差带来的各种假象出发，本文首先对比分析了速度误差对叠后深度偏移和叠前深度偏移的影响，发现偏移剖面的深度误差仅与速度模型的误差有关系，与具体的偏移方法没有直接的关系；然后对一个复杂的透镜体模型进行了波动方程叠后正演和偏移计算，详细地讨论了不同的速度误差带来的各种假象，发现速度误差不仅会带来深度误差，而且会造成构造体的形态变化，下覆地层同向轴的扭曲，还可能引起地层同向轴的频率发生变化，给资料解释带来一定的假象。

METHODS: Rabbit models of autogenous vein graft were generated in both groups. After anaesthesia, a median incision was made at the neck to dissociate external jugular vein and common carotid artery of the left side. Following blood flow was blocked at the upper and down sides of the common carotid artery, blood vessels were transected to collect 4.0-5.0 cm external jugular vein at the left side, and placed among the common carotid artery at the same side after inversion. End-to-end anastomosis was performed using discontinuous ecstrophy.

两组兔均建立自体静脉移植模型，麻醉后颈前正中切口，游离出左侧颈外静脉及颈总动脉，在颈总动脉的上下两端阻断血流后，横断血管，取左侧的颈外静脉4.0~5.0cm，上下倒向后置于同侧颈总动脉之间，采用间断外翻法行端端吻合。

Results The main CTimages of adrenal neuroblastoma in children were bigger extrarenal tumor ,included :huge and irregular mass(6 cases ),regular mass (2 cases),calcification (87cases),cystic degeneration or necrosis (1cases),bleeding(2cases),crossing of the midline (5cases),wrapping retroperitoneal major vessels (4cases),retroperitoneal enlargement of lymphnode (7 cases),The masses were heterogeneous enhancement.

分析2004年10月～2008年10月经手术病理证实的8例儿童肾上腺神经母细胞瘤的CT表现，如形态，密度及周围结构变化情况，结合临床资料，进行综合评价。结果儿童肾上腺神经母细胞瘤为肾外体积较大肿块，其中不规则肿块6例，规则2例，钙化7例，囊变坏死1例，出血2例，越过中线5例，包绕腹膜后大血管4例，腹膜后淋巴结肿大7例，肾脏向后外侧移位6例。

The results indicate that the forward launch gains a n advantage in capability over backward launch, but the difficulty of forward launch is attitude control of the laun ch vehicle.

结果表明，内装式空射运载火箭采用前向发射方式比采用后向发射方式具有较大的性能优势，但运载火箭的姿态控制是前向发射的技术难点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
