Dissector operation is based on the principle of electronic emission, where the image incident on the photosensitive surface produces an electron beam whose cross section is roughly the same as the geometry of the tube surface.

解析器是根据电子发射的原理操作的，图像入射在感光面上产生电子束，电子束的交叉部分大致与晶体管表面的几何结构一样。

In the second chapter, we discussed the construction of maximal sets on block triangular matrices over a division ring.

第二章研究分块三角矩阵空间极大集的几何结构。

Telecom corporation need do research on selecting and laying out of power cable, in this paper technique of trefoil laying out is analyzed in detail according to eddy current loss.

对电力电缆的选型与分层走线技术进行相关的研究成为重要课题，本文主要分析了电力电缆呈三角型几何结构分层走线技术。

The influence of measurement geometry and ultrasonic source and receiver are analyzed to highlight their role in the estimation of elastic stiffness from scattering coefficients. Extrinsic properties, such as surface roughness, are briefly dealt with.

报告中分析了几何结构、超声波源以及接收体对检测的影响，强调了它们在弹性刚度、散射系数的评估中的作用，涉及了非固有特性的处理。

Forming part of the paragraph L / D ≥ 1 and for forming slip paragraph 1 / 2 of the gas-assisted die, as the entrance to the storage of elastic strain energy in the gas-assisted paragraph has been fully released from the mold after the swollen out of the mouth than with the Import model geometry has nothing to do

对于成型段部位L/D≥1且滑移段为成型段1/2的气辅口模，由于入口储存的弹性应变能在气辅段已经完全释放，离模后挤出胀大比与口模入口几何结构无关。

In this paper, the electronic properties and energy band structure of series PPV derivatives were calculated by chemistry method.

本文对实验上合成的一系列PPV衍生物的几何结构、电子光谱等进行理论研究。

The novel design method is the excellent solution for the simulation challenge that power electrical device and the magnetic path device are applied to the power system since it's the intuitionistic, effective and exactable. This method is also the innovation for the design and the application of the power electromagnetism device.

论文首次将SABER仿真软件引入到消弧线圈设计中，其中所采用的磁路模型、线圈模型不仅能描述消弧线圈的电气特征，还能反映消弧线圈铁心和线圈的空间几何结构、使用材料参数等物理特征。

In the fiber cladding and core, the optical fields are represented by the sum of the Bessel and modified Bessel functions, respectively. In the polymer and metal, the optical fields are written to the sum of the exponential functions.

针对热极化光纤的特点，本论文完成了以下理论分析和实验工作： 1、首次利用圆波导模型和标量近似理论对具有复杂几何结构的极化D型光纤的传输特性进行了理论分析。

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。
