方向

After compared with some published algorithms, an algorithm to detect the directional field of fingerprint based on Walsh transformation was proposed.

为此，经过分析比较以往检测纹路方向的算法，根据指纹图的特点，提出了一种用Walsh变换检测纹路方向的算法。

Fingerprint directional image/field is a key technique of automated fingerprint identification system.

该算法是利用直方图滤波技术对指纹点方向图进行滤波处理，得到连续分布方向图。

Using the directional field information,Poincare index can detect the discontinuous point in the directional field——singularities.According to the number of singularities,their position and structural character of fingerprint's ridge lines,the basic category of fingerprint is classified.

利用指纹图像的方向场信息，用Poincare索引值检测出方向场中不连续的点——奇异点，根据奇异点的数目和相互位置关系以及指纹脊线的结构特征确定指纹的基本类型。

It has unique substrate specificity, and required minimal sugar chain in the degradation direction and synthesis direction of trisaccharide and disaccharide separately.

该酶具有独特的底物特异性，其降解方向和合成方向所需的最小糖链长度分别为三糖和二糖，均比普通的葡聚糖磷酸化酶少一个糖基以上。

Bring up to break up each time, the head quarter reminds of an end that sentence:Want to walk, I can not find a direction, want to stay, can not find a direction, I hope my you can you of, the feeling, think, love, hate, even distress of a fit of fantasy, mind all to I a vomit for quick, I will patiently listen to your ground of Xu Xu say that finish, let you feel more easily, worked to fail, lived to discommode, you can trust ground to seek me to tell to say, I would resolve for you, I am the person whom an understand matter manage, not a person who don't preach a reason!

每次提起分手，总会想起最后那句话：想走，我找不到方向，想留，找不到方向，我希望我的你可以把你的、所感、所想、所爱、所恨、甚至一时的梦幻、心灵的伤痛都对我一吐为快，我会耐心听你絮絮地说完，让你倍感轻松，工作失败了，生活委屈了，你可以放心地找我诉说，我会替你分解，我是一个明白事理的人，不是一个不讲道理的人！

While these gradients could all be detected reasonably well,we found a slight shift in discriminability in favour of positive gradients and found that surfaces with no gradient at all were more likely to be judged to have a positive gradient.

让被试辨别表面质地密度变化的方向，结果发现被试能够很好地判别表面质地密度变化的方向，但在判别正向变化的表面时显得更准确；当表面密度没有变化时，被试倾向于判别为正向变化。

To cause to lose one's bearing s; disorient.

使失去方向；使迷失方向。

To cause to lose one's bearings; disorient.

使失去方向；使迷失方向。

To cause to lose one's bearings; disorient

使迷失：使失去方向；使迷失方向

In the words of the report on our curricular reform, we aim to "unsettle presumptions …. to reveal what is going on beneath and behind appearances, to disorient" our students and then "help them to find ways to reorient themselves."

用学生对我们的课程所作的评语来说，我们的目的是"动摇他们先入为主的想法……，揭示在表象以下，或以外，的事物，摆脱他们原定的方向，再帮助他们重新找到方向。"

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
