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.

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。
