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。

Discontinuous geographic variation is often set aside as a special case.

不连续地理变异，人们往往作为一种特殊情况把它分开。

However, in a significant number of cases of female-positive discordancy, that settling down had taken place ten or more years in the past.

但是在大量女性导致的不一致关系案例中，地理上的定居发生在过去的10年之前甚至更早。

The popular and great cultural and art works acts as the epitome of the society on one hand, and on the other hand,with profounding philosophical thought, logicial discursion, and even rich and broad knowledge and history of Astronomy,geology,medicine and science, improve our knowledge toward the society.

一些著名的、优秀的文学艺术作品，不仅是当时社会的缩影，可以帮助人们深刻认识这个社会，而且蕴含着深刻的哲理思想、逻辑推理，乃至天文、地理、医学、科技等广博丰富的知识和史

Exile Tibetans are numerically dominant in the USA, and it is their views that set the discursive terrain.

在美国，流亡藏人在数量上居主导地位，这种不着边际的地理定位也正是他们的观点所在。

Thus the existence of our city of geographical dislocation.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
