After that, the important equation for calculating reverberation time is given based on the definition of reverberation time and least squares method. Finally, we use our new method to calculate reverberation time in a rectangular enclosure; we also compare our results with those given by experiment and Sabine's equation. The comparison shows that the new method is more effective and accurate than Sabine's equation in calculating reverberation time of small enclosures.

给出了描述小尺度封闭空间内声场的有限元模型；在该模型的基础上推导了计算小尺度封闭空间内混响时间的方法，并编制了相应的计算机程式；在算例部分，计算了一矩形封闭空间内的混响时间，通过与实验结果进行比较，验证了这一方法的正确性。

In general cases, the demixing matrix in ICA is not in the standard Euclideanspace but in the Riemannian space. Thus the tradition gradient direction is not the speedest direction.

一般情况下， ICA中的解混合矩阵所在的参数空间并非欧式空间，而是黎曼空间，因此，传统梯度所得到的方向并非最速方向。

Thirdly, the equations which are from the rigid transformation mode of surgical space and image space after identification of markers was solved to get the optimal transformation matrix and translation matrix of the two space.

用识别的数据建立手术空间和图像空间的刚体变换模型，再用最小二乘法解方程组得到两个空间的最优变换矩阵和平移矩阵。

The root partition requires some space to be left free for logs , root folder, and so forth, and will warn you when it gets "full"(all the space is used up except for what is set aside for logs).

home目录占到95％也不存在什么问题，而主分区通常需要一些剩余空间来处理日志文件和根文件夹等，故在除了日志空间外，其他空间都即将用尽的时候，系统将会出现警告。

In Experiment 1, the pattern of spatial attention shift was examined by instructing participants to saccade to the cue.

实验一要求被试将眼睛跳往提示刺激处，通过对线运动错觉的分析确定该条件下的空间注意转移规律；实验二要求被试在将视线保持在注视点处的条件下判断目标色块是否出现，以探明线运动错觉是否受对目标色块前注意阶段加工的影响；实验三要求被试将眼睛跳往提示刺激的对侧，分析眼跳位置与提示刺激空间方位的一致性对空间注意转移的影响。

This method exploits eigenstructure of thd received signal's sample correlation matrix in which the observation space can be partitioned into a signal subspace and a noise subspace.

该方法利用了接收信号协方差矩阵的特征结构，把观测子空间分解成为信号子空间和噪声子空间。

In the case where the sample covariance matrix is given, we perform the spatially smoothed Lanczos algorithm to fast compute the basis vectors for the signal subspace and the noise subspace.

如果阵列协方差矩阵是已知的，我们采用空间平滑的Lanczos算法快速估计信号子空间和噪声子空间。

For the case where the sample covariance matrix is unknown or the sample support is not sufficient to form the sample covariance matrix, we carry out the spatially smoothed CSA-MSWF to quickly find the signal subspace and the noise subspace.

如果阵列协方差矩阵是未知的，我们采用空间平滑的CSA-MSWF快速计算信号子空间和噪声子空间的基矢量。

This paper discusses wood surface visual quality of different genealogy of Eucalyptus pellita. The results showed that the color characteristics of heartwood and sapwood all have their distribution rang in XYZ(1964) color system, CIE(1976) L*a*b* color system and Munsell color system.

对人工林粗皮桉不同家系的木材表面视觉性质进行了研究，结果表明：粗皮桉心材和边材材色在XYZ 空间（1964）、CIE（1976）L*a*b*均匀色空间及孟塞尔色空间中，均有一定的分布范围。

Gnoclip - Gnoclip is a desktop swicher for GNOME, similar to the Window Maker clip. It has arrows to switch to the previous/next workspace, a menu with workspace names which also allows you to change workspaces, and support for screen names in Sawfish.

Gnoclip是一个GNOME的桌面交换开关，类似于 Window Maker，它提供了箭头指向前一个和后一个工作空间，也有一个带有工作空间名的菜单指出了你要转到的工作空间，它也支持屏幕菜单。

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。
