The subunits composition of heteromeric channels might give rise to diverse resulting biophysical and regulatory properties relating to ion conductance. The studies on the TRP channel assembly mechanism and function of heteromeric channels are getting much concern.

不同亚基所形成的异源通道具有不同的生物物理学功能和药理学特性，因此TRP通道的组装机理和异源组装通道的功能研究成为该领域的热点而日益得到关注。

For example, IEEE 802.16e supports vehicle speed up to 120 km/hour, and IEEE 802.20 supports vehicle speed up to 250 km/hour. OFDM systems can be used efficiently in time invariant environments with one-tap equalizers. However, subcarriers are no longer orthogonal to each other in time-varying channels, and this causes the intercarrier interference and degrades the system performance.

传统的正交分频多工系统可以有效率地使用在非时变通道中，且仅需简单的等化器，即可修正通道效应，但在移动的环境中，通道随著时间改变，使得接收端的子载波失去正交性，因而导致子载波之间的相互干扰，使得解调变后的效能降低。

For example, IEEE 802.16-2005 supports vehicle speed up to 120 km/hour. OFDM systems can be used efficiently in time invariant environments with one-tap equalizers. However, subcarriers are no longer orthogonal to each other in time-varying channels, and this causes the intercarrier interference and degrades the system performance.

In this thesis, an improved method is proposed to overcome the problem that the circular color histogram method does not take the spatial information of colors into account , combines spatial distribution information with image color features. The presented method adopt color space which has the visual uniform , three components carries on no laddered quantification, three components weighting summation composes the row of the circular color histogram construction, and improves retrieval quality, while rotation and translation invariance of color histogram are kept.

针对颜色直方图对图像的空间信息表现不够的问题，本文提出并实现了环形颜色直方图的改进方法，将图像颜色特征和颜色的空间分布信息相结合，采用具有视觉一致性的颜色空间，并把各通道分别进行非等间隔量化，采用各通道向量加权的形式把各通道组合为一个特征向量，提高了检索质量，并保持了原有算法的有效性和旋转不变性。

另外 ，还根据高速摄影仪所拍摄到的等离子体通道直径的扫描照片，计算了在放电 3 0 μs后通道内的压力为约 4 9MPa ，通道半径和壁速分别为 4mm和180m s。

The bad thing is that the DXT compression formulas for color images used in DirectX favors only the green channel (usual 30%, 59%, 11% formular), the blue/z channel isn't that important (especially if we renormalize later), but the image quality can be improved by preserving the red channel better.

坏的是，在使用DirectX的彩色图像DXT压缩公式主张只有绿色通道（通常30％，59％，11％公式），蓝/？通道并不重要（尤其是如果我们归一化后），但图像质量可以改善红色通道保存较好。
