In this paper, a method, which is based on GPS Time system, is applied to synchronize all GIBs. With GPS receiver's 1PPS output , GIB can compensate for the crystal oscillater's drift. 4. Mathematic Model of UGPS Based on the principle of hyperbola intersection, an iterative algorithm and an analytic algorithm are deduced to resolve system equations with four GIBs observations. It can also be used to resolve the approx coordinate with more than five GIBs'observations.

Vocalist Rosemary Clooney's rise to fame in the '50s came on the strength of songs that in many instances were without question novelty tunes; she's not a vocal improviser like Carmen McRae , Betty Carter , or Sarah Vaughan . She is an excellent lyric interpreter, has fine timing, phrases skillfully and intelligently, and performs with the dramatic quality evident among all great singers.

Such doubts havesitimulated the researchers'curiosity and start to explore the students' terms This research proceeds by observation interview test using learning sheets and etc The purpose is to explore students' terms of scientific concepts sources of terms connections between students' usage nomenclature and chooses of usage The results of the research are as follows: 1 There are five kinds of naming principles for students' terms of scientific concepts: appearance habit function replacing and sound Appearance principle contains three categories: color shape and partial construction; habit principle contains custom and ability; replacing principle contains reality and non-reality 2 Students' terms of scientific concepts come from two ways: self-acquisition and learning through senses The former way is only a bit more common than the latter 3 There are three different relationships between students' usage of terms and nomenclature: one both the same in usage and meaning; the other both different; another different usage but the same meaning Normally terms that students used are various from nomenclature in the aspects of usage and meaning only a few would match and even rare for "Synonyms" to occur 4 Alternative options for students' scientific terms are maintenance adaptation or co-existence with formal scientific terms The most common way of selecting usage of terms is to maintain Sometimes students would adapt themselves once learn of scientist's term However some believe that very odd chances for both could exist at the same time

这样的疑问深深引起研究者的好奇，著手探索学生科学概念所使用的语言。本研究透过观察、访谈、学习单施测等方法来进行，目的在探讨学童在科学概念上所使用之学生惯用语、学生惯用语来源、学生惯用语与科学家用语之关联性、学生惯用语选择。研究结果如下：一、学童在科学概念上所使用之学生惯用语的命名原则有五种：外型、习性、功能、藉代称呼及声音，其中外型原则有颜色、体型及部份构造三类目，习性原则有习惯及能力两类目，藉代称呼原则有实体及虚拟两类目。二、学童在科学概念上所使用之学生惯用语有两种来源，分别为自己称取和听来。学生惯用语来源较多为自己称取，透过其他方式听来少一点，但两种来源的比率差距甚小。三、学童在科学概念上所使用之学生惯用语和科学家用语的关系有三种，分别为用语意涵均相同、用语不同意涵相同和用语意涵均不同。学生惯用语通常和科学家的用语是不同的，且其意涵也不同，只有部份学生惯用语和科学家用语意涵均相同，至於学生惯用语和科学家用语不同但意涵相同的极少。四、学童的科学概念相关学生惯用语选择有三种，分别为维持学生惯用语、改变成科学家用语和科学家与学生惯用语皆可。学童的科学概念相关学生惯用语选择，以维持学生惯用语最多，而有些时候学生会在得知科学家的用语后改变成科学家用语，但认为科学家用语和自己使用的学生惯用语皆可的则很少。
