Traditional straightness measurement, such as leveling rule, gradienter, reinforcing wire, even though simple in detecting apparatus and adopted widely, are of certain limitation, low accuracy, low efficiency, and cant guarantee the performance. On the other hand, some other measuring devices cannot be widely used because of value.

传统的直线度检测方法，如平尺法、水平仪、钢丝法等，虽然检测器具简单，实际中常被采用，但各自都存在一定的局限性，测量精度不高，效率低，性能无法保证；而有些仪器却造价过高不利于广泛应用。

With the development of the ESA's GOCE mission and declaration of relative technology reports, we have many chances to know the GOCE satellite and its payloads, especially the gravity gradiometer. The paper introduces the gradiometer's measurement principle and instrument's design. All of this is based on tracking the development actuality, The purpose is to make more distinct and deeply understanding of this domain. Also we want to provide possible reference to some institutes when they study in this domain.

随着欧空局GOCE项目的进一步深入及相关技术报告的公布，人们对该卫星及其有效载荷有了更多的了解，尤其是倍受关注的核心器件重力梯度仪有了更多认识的机会，本文在跟踪当前欧空局研制中的星载重力梯度仪的测量原理、仪器设计的基础上进行了综合、分析和总结，以期对该领域的研究有更清晰、深入的了解，同时为国内进行该领域研究的机构提供可能的参考。

Satellite gravity gradiometry is a new domain of studying the detection of gravity gradients in space and their applications, in particular, suitable for detecting the short wavelength characteristics of the earth's gravity field At present it is still at the stage of developing the ultra-sensitive tensor gradiometer and carrying out the pre-research of applications.

卫星重力梯度测量是研究空间重力梯度探测与应用的新领域，特别适于检测地球重力场的短波特征。目前它尚处在研制超灵敏张量梯度仪器和应用预研究的阶段。

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.

交际能力和语法的关系应该是目标与途径的关系。
