The coat is relatively short to medium along the sides of the body, with the length of the coat increasing around the shoulders and neck, down the back, over the rump, and in the breeching and plume.

身体两侧的被毛较短，向前延伸到肩部和脖子的时候，被毛逐渐变长，向下和向后，到臀部及尾巴，被毛都是逐渐变长。

The preliminary results show that the maximally evoked responses are at a deeper layer of the cortex. The value of this depth form surface of the cortex is about 900 m. A twodimensional recording was performed at this depth to find the responsive center or locus. The result shows that a dipole can be used to represent the responsive center with a coordinate of 1.9 mm posterial and 1.9 mm lateral to the Bregma. These finds should be valuable for further studies about pain.

由初步结果得知雷射所诱发的场电位分布在大脑皮质体感觉区的较深部组织，自表面算起约为900 μm处为最大反应之深度，而在此深度水平切面之反应中心则位於以前囱门为座标原点向后约1.9 mm 向外测1.9 mm 处，此反应中心呈现一个偶极的现象，这些资料对往后之痛觉研究十分重要。

The Invid's snout dropped open when he saw Wolff standing there armed to the teeth, and he immediately fell backward against his coconspirator, hoping Wolff would read it as Burak attempting a capture.

因维人看到沃尔夫全副武装站在那里时，尖嘴惊讶地张开合不拢，随后立刻向后摔倒，倒向自己的同谋，希望沃尔夫会以为伯拉克在擒拿他。

Experimental results show the recognition rate of the method is 95%for a known expresser and 72% for a novel expresser. Aiming at the shortcomings of optical flow technique,two improved optical flow algorithms are presented.One way is to introduce forward and backword constraint eqution and Hessian matrix of optical flow equation is computed.The well- posedness of each point of local neighbourhood is examined and the weight of Lucas-Kanade's method is defined as the reciprocal of the conditioning number of its Hessian Matrix.

3针对传统光流法的缺点，分别提出了两种不同的改进方法：其一为引入前向-后向光流方程，计算其Hessian矩阵，把Hessian矩阵条件数的倒数作为Lucas-Kanade光流法的加权阵，可有效消除局部邻域中不可靠约束点，同时提高基本约束方程解的稳定性；其二为针对传统光流法只适用于刚体运动的特点，在扩展约束光流方程的基础上引入了div-curl样条函数作为扩展光流约束方程的附加约束条件，给出了一阶和二阶div-curl样条约束下光流的数值解。

They share many similar or the same featutes with Archaeopteryx or other primitive birds, such as: U-shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and "modern feathers"with rachis and barbs etc.

奔龙类是一类较为特殊的手盗龙类，它具有许多与始祖鸟Archaeopteryx甚至其它早期鸟类相似或接近的特征，主要表现在：叉骨U形与始祖鸟和孔子鸟类的相同，背肋钩状突在孔子鸟类和个别反鸟类中也存在，肩臼窝绝大部分指向侧方类似于始祖鸟，肩胛骨与乌喙骨间的夹角非常接近90°也和始祖鸟的相似，前肢从比例上讲显得较长，大的半月形腕骨使肘部能向侧方折过来，耻骨伸向后下方，距骨上升突与原始鸟类中的为同源结构，羽毛已有显著的分化且具备了现代羽毛的基本结构等等。

The remaining part of the penis is composed of gristle; it is easily susceptible of enlargement; and it protrudes and recedes in the reverse directions to what is observable in the identical organ in cats.

阴茎的剩余部分由软骨组成；它是容易放大的；它突出，反方向向后倾斜，如同猫的相同器官可以观察到的。

Have a good day. Before I head off to work I wanted to say I have been watching someeveryone in TV land he was wearing ...a red shirt and his hair pulled back and was telling the public to hear him out and

Karen，在我下班之前我想说一件事儿我在电视上看见michael向公众发布陈词，他穿着一件红色衬衫，头发向后梳起。

Dancing back in heart-thumping surprise, he quickly saw that rather than a mere hole it was a hatchway that gaped in the floor before him, its door flung open and back.

由于惊奇，心急剧地跳着，他忙向后跳开了一步，很快地发现，那并不仅仅是一个洞，而是他前面的地板上，有一个通道口打开了，它的门被掀开了，向后面大敞着。

For a while, perhaps one or two years, Cycle 23 and Cycle 24 will actually share the sun, making it a hodgepodge of backward and forward spots.

有一段时间，也许一年或两年，周期23和24周期将真正分享阳光，使它成为一个大杂烩向后和向前点。

How? If you stand under a doorway and the door jamb falls forward or backward you will be crushed by the ceiling above..

如果你站在门口下，门框侧墙不论是向前或向后倒塌，你将会被在上面的天花板压碎…如果门框侧墙倒向两边，你将会在门口被切成一半，不管何种方式，就是死路一条

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。
