Unlike the previous method, however, the proposed algorithm obtains the new transformed matrix by taking the conjugate operation to the forward and backward spatial smoothing covariance matrix of the received data, so that the modified covariance differencing matrix which is a Hermitian matrix of zero real part can lower the computation load effectively during the eigenvalue decomposition.

不同于以前的算法，提出的算法通过对接收数据的前后向空间平滑协方差矩阵进行共轭运算得到新的变换矩阵，因此修正后的协方差差分矩阵是个实部为零的厄米特矩阵，从而有效地降低了特征分解过程的计算量。

In this paper, a novel feature MFCC_FWD_BWD, which is based on forward-backward difference dynamic parameters, is presented to satisfy the requirement that the feature construction matrix is invertible for PMC.

本文首先提出了一种基于前后向差分动态参数的特征MFCC_FWD_BWD，该特征满足PMC对特征构造矩阵可逆的要求。

Changes of erosion and accumulation of the seabed before and after the project The general characteristics of the pattern of erosion and accumulation of the seabed near the scheduled project both before and after the scheduled project are as the following: accumulation occurs at the areas lower than–10 isobath; some suspended sediment is deposited near the coast due to the relatively small tidal current with a monthly accumulation rate of 2-6 mm; while a slight erosion occurs in the areas deeper than–10 isobath with a monthly accumulation rate of .2 mm.

5工程前后海底冲淤变化工程前后海底冲淤相同的地方是：大致沿-10m等深线向近岸呈淤积状态，近岸由于潮流流速小，一些悬沙落淤，月淤积量在近岸附近约2-6mm；而-10m等深线以深基本上呈轻微冲刷状态，月冲刷量一般在0.2mm以下。

Furthermore, based on the experience of other countries, oligarch monopoly is the mature sign for automobile industry, and industrial concentration is its embodiment on organization structure.

Growth curves of different passges (P=5 and P=10) of rabbit MSC were drawn according to the MTT test. Modified Woodbury protocol was adopted to induce the neuron-oriented differentiation of rabbit bone marrow-derived MSC, that is, BME was applied to MSC in low dose and a relatively short span (D=3mM, and T=2h).

The corona type aurora mainly occurs at polarward and overhead of Zhongshan Station during postnoon and around midnight. The band type aurora mainly appears during postnoon, while during evening and around midnight only appears at equatorward.

冕状极光主要出现在子夜附近和午后的极向侧和天顶，在傍晚出现很少；带状极光主要出现在午后和赤道侧的傍晚与子夜；极光浪涌主要出现在子夜前后；向日极光弧则主要出现在子夜前后，子夜前比子夜后多，极向和天顶比赤道侧多。

And Toona sinensis were steam-treated at temperature 70℃ and 90℃ for 4 h and 8 h. The radial gas permeability and tangential gas permeability of the steam-treated specimens were compared with those of non-steam-treated one.

处理条件为：杉木和马尾松木材的汽蒸温度分别为90、100℃，假水青冈和香椿木材的汽蒸温度分别为70、90℃，处理时间分别为4 h和8 h，并对汽蒸处理前后木材的弦向和径向气体渗透性分别进行了测定。

The results show that with the increase of drill wears, the box dimension and the information dimension as well as the correlation dimension of drilling force signals appear obviously to have the downtrends. Accordingly, this characteristic can be effectively used to realize the monitoring of drill wears.Aiming at the characteristics of the highest overlap of the feature modes in each drill wear condition, the hidden Markov model is put forward to resolve the drill wear monitoring.

针对各钻头磨损状态下特征模式高度重叠的特点，提出采用隐马尔可夫模型HMM解决钻头磨损监测的思想，对1肠IM在钻头磨损监测中的原理及实现方法进行了系统的研究，完成了基于前后向算法和Baurn一Welch算法进行模型训练和识别的具体实施步骤，建立了基于S服网络的矢量量化器，解决了钻削力特征矢量的融合与编码问题。

The analytical expresses of scattering field are obtained based on the boundary condition of a sheath helix model. The effects of the pitch angle and the electrical size of the helix on the resonant behavior are also investigated. It is shown that the resonant behavior of the forward/back scattering far field only depends on the pitch electrical size and the radial electrical size, and that the turn of the helix has no effect on the resonant behavior.

根据sheath螺线管模型的边界条件获得了散射场的解析表达，同时研究了螺线管在共振状态下电角度及螺间距的影响，表明远场的前后向散射的共振状态只依赖于间隙的电场大小及径向的电场大小，而螺线管的倒转不影响谐振状态。
