On moving base, a new initial alignment algorithm for strapdown inertial navigation system is proposed. In the algorithm, two special inertial frames, the initial-time inertial frame (i0 frame) and the initial-time SINS body inertial frame (ib0 frame), are defined and are selected as calculation reference frames, then, the calculation of initial alignment direction cosine matrix is expanded into three parts:(1) the DCM between i0 frame and the navigation frame will be easily obtained via local geographical coordinates and initial alignment time;(2) attitude updating using gyro samples gets the DCM between SINS frame and ib0 frame;(3) by explaining SINS specific force equation in SINS body frame, the relation between velocity log, accelerometer measurement and gravity acceleration is established to achieve the constant DCM from ib0 frame to i0 frame.

在运载体运动情况下，提出了一种适用于捷联惯导系初始对准的新算法，该算法以惯性空间为参考基准，即建立了初始时刻惯性坐标系（i0系）和初始时刻捷联惯组惯性坐标系（ib0系）两个惯性坐标系，将初始对准姿态矩阵的实现分解为三部分：（1）通过地理位置和初始对准时间求解i0系至导航坐标系的变换矩阵；（2）使用姿态更新算法实时计算捷联惯组相对于ib0系的变换矩阵；（3）通过惯导比力方程变形，获得测速仪辅助测量、加速度计输出和重力加速度之间的关系，从中可以求解出从ib0系至i0系的常值变换矩阵。

The calculation of initial alignment direction cosine matrix between SINS body frame and navigation reference frame is expanded into three parts:(1) the DCM between i0 frame and n frame is easily obtained via local geographical coordinates and initial alignment time;(2) by expressing SINS specific force equation in b frame and by the aid of external velocity log, the constant DCM from i(subscript 0) frame to i0 frame is achieved;(3) attitude updating using gyro samples gets the DCM between b frame and i(subscript b0) frame.

The polysemous development among the three verbs is explained in terms of the hypotheses about the frame-to-frame transferring and the conceptual schema requirement for triggering the individual verb in a frame to be transferred into another frame. Furthermore, among the three verbs, only biaoshiI is a fully representative member of the source domain, i.e., the Statement frame, and thus capable of being extended to other domains, i.e., the Encoding and the Evidence frames. Here, lexical membership in the source frame or frame-representativity is the key to semantic extension.

为了解释这三个动词语义差异的现象，我们指出了框架到框框间转换的假设和让一个动词从一个框架移动到另一个框假所需的概念基模要求，并且进一步提出「框架代表性」(frame-representativity)的原则，说明「表示」做为「来源领域」最具代表性的一个词汇，因此可以从「陈述性的框架」延展到其他的框架。

The video coding method includes the steps of dividing input frames into one final low-pass frame and at least one high-pass frame through a motion compensated temporal filtering, coding the final low-pass frame and then decoding the coded final low-pass frame, re-estimating the high-pass frame by using the decoded final low-pass frame, and coding the re-estimation high-pass frame.

所述视频编码方法包括以下步骤：通过运动补偿时域滤波将输入帧划分为一个最终低通帧和至少一个高通帧；对最终低通帧编码并随后对编码的最终低通帧进行解码；通过使用解码的最终低通帧重估所述至少一个高通帧；以及对重估的高通帧编码。

As for frame synchronizer, the recognizer of the frame pattern and its performance are analyzed in details. The probability of catching frame pattern upon one pass is deduced. Based on these, the relationship between optimum frame pattern length and the frame length , the allowable error tolerance and the channel errors, the protecting parameter α、βand the threshold level are derived. Consequently, a new type of adaptive frame synchronizer is presented.
