However, most of these investigations focused on the rotating beams or plates undergoing a prescribed large overall motion, where the effect of large overall motion of the reference frame on elastic deformation was considered but at the same time the beam's elastic deformation couldn't influence the large overall motion of the reference frame because the large overall motion is known a priori. In fact, this kind of problem on the dynamic stiffening is a structural dynamics problem in a non-inertial frame.

值得指出，上述这些研究工作都局限于大范围运动为已知情况下的非惯性系下柔性体的动力学性质，实质上是一个非惯性系下的结构动力学问题，只考虑了大范围运动对变形运动的影响，而没有充分考虑到大范围运动和变形运动之间的相互耦合作用，这种耦合作用是单向的。

When motion is towards the location of the addressee,come is much preferable to go in English while both laiand quare common in use in Chinese.When motion is towards the location of the addressee at a past time,laimust be used in Chinese if the addressee is there at the time of utterance while qumust be used if the addressee is not there at the time of utterance.By contrast,come is used in English either when the addressee is there or when he is not there at the speaking time,while go is only used when the addressee is not there at the time of utterance. When both the speaker and the addressee serve as the figure,which is indicated by the phrases like with me/us/you in English and the phrases like he ni,he nimen,gen wo,gen womenin Chinese,come is much preferred to go for the figure"s motion,while in the same context,quis used for the figure"s motion.What"s more,come is more frequently used to indicate the figure"s movement towards a place where neither the speaker nor the addressee is located at the time of utterance,while quis often used in Chinese in the same case.

当移动体朝向听话人所在方位移动时，英语多用come，汉语可用"来/去"；当移动体在一个过去的时间朝向听话人所在方位移动时，汉语可用"来"表示听话人在说话时间仍在位移参照点，用"去"表示听话人在说话时间已不在位移参照点，而英语在两种情况下都可用come，用go则表示听话人在说话时间已不在位移参照点；当说话人和听话人一起作为移动体而句中主语只是说话人或听话人一方时，英语多用come，汉语多用"去"。

Based on Pseudo-linearization and least square methods, the bearings-only target motion problem was studied under the conditions that the target takes uniform rectilinear motion in 2-dimensional space, the single observer takes uniform rectilinear motion first, and then takes rectilinear motion with constant acceleration. The necessary and sufficient observable conditions, some unobservable conditions are gained.

基于拟线性处理和最小二乘方法，在目标作匀速直线运动，单观测站作匀速直线运动，进而作匀加速直线运动的机动情形下，研究了二维纯方位系统的可观测性，得到了系统可观测性的充要条件以及系统的某些不可观测的条件。
