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.

In Southeast Asia, the contradictory movement of modernization and globalization is born of the non - synchronism between them, which is especially evident with Southeast Asian minorities whose marginalization has been aggravated. Their marginal position is shaped by their backward residential space and low social rank, and also results from the disjuncture between social and economic developments.

在东南亚，现代化与全球化的矛盾运动产生于二者的不同步，这在该地区的少数民族身上表现得特别明显，这些弱势群体的边缘化进一步加剧，而其边缘地位是落后的居住空间和低下的社会层级所决定的，同时也是经济与社会发展相脱离的结果。
