Following postgraduate research in optical fibre laser gyroscopes, he worked for Thomson Scientific from 1994 to 2007 as an indexer and abstractor of academic and scientific papers for the Inspec database, specialising in electronics, optoelectronics and semiconductor electronics, and later telecommunications.

acDonald 先生是一位经验丰富的电子和电气工程信息科学家，研究生阶段的研究内容是光纤激光陀螺系统。1994年至2007年间，他一直从事 Thomson Scientific 旗下 Inspec 数据库学术和科技文章，主要是电子学、光电子学、半导体电子学，以及电信领域文章的索引和摘要编辑工作。

Accordingly, study and development of fiber Brag grating accelerometer is very significant.

研究和开发新型的光纤光栅加速度传感器具有十分重要的意义。

In Chapter 1, fiber-optic acoustic sensors and its development are briefly reviewed.

第一章对光纤声传感器和目前的发展状况进行了评述。

A semiconductor optical amplifier model is employed in which the self birefringence of SOA due to stress is taken into account. The integral action of the birefringence of the fiber and the PC is represented with a Jones matrix of linear retarder.

半导体光放大器采用由张应变引起的自身双折射理论模型，光纤的双折射效应和偏振控制器对光的偏振调节作用综合用一个线性双折射琼斯矩阵表示。

The design methods of system structure, optical fiber transmission adapter and transmission protocol were presented in detail.

The colorimetry can largely lower the blast-off rate which influence the result of temperature measurement.

消耗型光纤辐射温度计的设计方案共分为三大部分：光纤测温系统、比色系统、单片机。

Furthermore, the double-loop BFOG program is proposed, which provides a potential solution of Kerr effect error in Brillouin fiber-optic gyroscope.

提出了一种全新的双环布里渊光纤陀螺方案，为布里渊光纤陀螺的克尔效应误差抑制提供了一种潜在的解决途径。

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。
