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。

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.

And E.N.E: Had they seen the Island, as I must necessarily suppose they did not, they must, as I thought, have endeavour'd to have sav'd themselves on Shore by the Help of their Boat; but their firing of Guns for Help, especially when they saw, as I imagin'd, my Fire, fill'd me with many Thoughts: First, I imagin'd that upon seeing my Light, they might have put themselves into their Boat, and have endeavour'd to make the Shore; but that the Sea going very high, they might have been cast away; other Times I imagin'd, that they might have lost their Boat before, as might be the Case many Ways; as particularly by the Breaking of the Sea upon their Ship, which many Times obliges Men to stave, or take in Pieces their Boat; and sometimes to throw it over-board with their own Hands: Other Times I imagin'd, they had some other Ship, or Ships in Company, who upon the Signals of Distress they had made, had taken them up, and carry'd them off: Other whiles I fancy'd, they were all gone off to Sea in their Boat, and being hurry'd away by the Current that I had been formerly in, were carry'd out into the great Ocean, where there was nothing but Misery and Perishing; and that perhaps they might by this Time think of starving, and of being in a Condition to eat one another.
如果他们发现这个小岛,我想他们一定会用船上的救生艇竭尽全力划到岸上来的。但看来他们一定没有看到小岛,只是鸣枪求救,尤其是他们看到我燃起的火光后,更是多次放枪。由此我头脑里出现了种种设想。首先,我想到,他们看到我点燃的火光后,必然会下到救生艇里拼命向岸上划来,但由于风急浪高,把他们刮走了。一会儿我又猜想,也许他们的救生艇早就没了,这种情况是经常发生的。当大船遇到惊涛骇浪时,水手们往往不得不把船上的救生艇拆散,甚至干脆扔到海里去。过会儿我又想,也许与他们结伴同行的船只,在见到他们出事的信号后,已把他们救起来带走了。我又想到,说不定他们已经坐上救生艇,可是遇到了我上次自己碰上的那股急流,给冲到大洋里去了。到了大洋里,他们可就糟了,那是必死无疑的。说不定这会儿他们都快饿死了,甚至可能正在人吃人呢!

As soon as they got to the Place where their other Boat lay, they run their Boat in to the Beach, and came all on Shore, haling the Boat up after them, which I was glad to see; for I was afraid they would rather have left the Boat at an Anchor, some Distance from the Shore, with some Hands in her, to guard her; and so we should not be able to seize the Boat.
那批人来到头一只小船停泊的地方,马上把他们自己的小船推到沙滩上,船上的人也通通下了船,一起把小船拉到岸上。看到这一情况,我心里非常高兴。因为我就怕他们把小船在离岸较远的地方下锚,再留几个人在船上看守。那样我们就没法夺取小船了。
