尺度

In chapter 5, heat mechanism and heat radiating forms of the hydraulic system faults are studied. Based on relationship between degree of the hydraulic system faults and thermal image shapes, multi-scale entropy of temperature field is taken to express the fault degree. Entropy of low frequency means its absolute temperature, and entropy of high-frequency means distribution of temperature field.

同时针对系统故障程度的不同，提出了用温度场的熵进行表征的思路，通过多尺度小波对原热场图像进行小波变换，提取其中低频分量的熵用来衡量其绝对温度大小，提取高频分量的熵来衡量其温度场的分布，给出了实验结果，通过实验结果分析，证明这种分析方法是可行的。

Then the digital audio signal is set into segments and DWT is performed. Finally the modulated signal is embedded in the coefficients with relatively large absolute value on middle frequency range detail signal adaptively. The original digital audio signal is necessary when detecting the watermark.

在应用扩频技术的算法中，首先将视觉上可辨的二值水印图像降维为一维序列，再将一维水印序列伪随机排序并与m序列作扩频调制，最后对数字音频信号进行分段离散小波变换，把经过调制的水印信息自适应地嵌入到原音频信号小波分解中等尺度绝对值较大的分量上。

As expiration granularity relates to a resource's inherent characteristics, we measure each resource's expiration granularity in relation to its own estimated lifespan and not along an absolute time scale.

As if time is absolute and can be measured by a standard ruler.

的单位，好像时间是绝对的，可用相同的尺度来量度。

Just as then in the question of astronomy, now in the question of history, the whole difference of view rested on the recognition or non-recognition of an absolute unit as a measure of visible phenomena.

现在的历史学问题正如当年的天文学问题一样，各种观点上的不同就在于承认或不承认一种绝对的单位作为看得见的现象的尺度。

ABSTRACT How to use scale space theory in computer vision is a new and open investigation field.

计算机视觉中如何应用尺度空间理论是一个新的、具有挑战性的研究领域。

For smaller ones, which are expected to be more abundant in number, occultation of background stars by TNOs as a way to study their properties has been proposed but without any definite detection so far.

然而我们可以藉由掩星的方式来估计出一些尺度比较小的但是数量很多的物体，一般来说我们可以藉由光学波段的掩星方法来寻找一些大小差不多在几百公尺到几公里的物体，而且也有一些成果。

For the averged regional status in iceage, the changes of the general circulation caused by the large-scale forcing is the main reason forming the differences between ice-age and present climate.

对于大尺度强迫，其局地效应主要通过定常波列型或大气遥相关型的全球效应对区域气候异常产生影响；而区域内局地的中尺度强迫，则主要是通过大气内部热力和动力学过程影响大气运动状况。

It is elucidated that research on each characteristic scale and the interferences between the characteristic scales are very significant.

每个特征尺度的研究，以及各特征尺度之间的关联过渡具有十分重要的意义。

With FDDA method, the precipitation echo reflectivity field gained by observation and three dimension wind field as well as other parameters obtained by retrieval are put into the usual mesoscale or smallscale numerical model, so that the inner structure of mesoscale or smallscale weather system is better researched and precipitation is estimated more exactly.

2利用四维同化方法，将单多普勒天气雷达观测得到的降水回波的反射率场以及用反演技术得到的三维风场及其它变量，加入到通用的中小尺度数值模式中，以便更好地研究中小尺度天气系统的内部结构，预测其演变，并提供更精确的降水估计。
