Ii an alteration of course towards a vessel abeam or abaft the beam.

对正横或正横后的船舶采取朝着它转向。

B A vessel shall be deemed to be overtaking when coming up with another vessel from a direction more than 22.5o degrees abaft her beam, that is, in such a position with reference to the vessel she is overtaking, that at night she would be able to see only the sternlight of that vessel but neither of her sidelights.

一船正从他船正横后大于22.5o 的某一方向赶上他船时，即该船对其所追越的船所处位置，在夜间只能看见被追越船的尾灯而不能看见它的任一舷等时，应认为在追越中。

B "Sidelights" means a green light on the starboard side and a red light on the port side each showing an unbroken light over an arc of the horizon of 112.5 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on its respective side.

舷灯是右舷的绿灯和左舷的红灯各在112.5o 的水平弧内显示不间断的灯光。其设置应使灯光从船的正前方到各自一舷的正横后22.5o 内分别显示。

A "Masthead light" means a white light placed over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on either side of the vessel.

桅灯是指安置在船首尾中心线上方，在225o 水平弧内显示不间断的白色灯光。其设置应使灯光从船的正前方到每一舷正横后22.5o 内显示。

RULE 21 Definitions "Masthead light" means a white light placed over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on either side of the vessel.

桅灯是指安置在船首尾中心线上方，在225o 水平弧内显示不间断的白色灯光。其设置应使灯光从船的正前方到每一舷正横后22.5o 内显示。

However,in practice, the excursion ,transmission refraction and optics aberrance of the laser beam will affect the measuring precision.

但在实际应用中，激光光束的漂移、传输折射以及光学畸变对测量系统的测量精度具有不可忽视的影响。

The formation mechanism of the absolute instability and gyrotron backward wave oscillations is analyzed, and the methods to suppress the parasitical modes are discussed.The nonlinear theory model of gyro-TWT is consummated by considering the influence of tapered magnetic field and waveguide radius, electron velocity spread, and waveguide loss on electron beam-wave interaction. The large-signal characteristic of gyro-TWT, such as launching loss and absolute instability, are also analyzed in detail. This work establishes the foundation for the development of a gyro-TWT amplifier.

重点研究了两段损耗波导结构和损耗陶瓷结构回旋行波管中的电子注-波互作用，分析了绝对不稳定性和回旋返波振荡的形成机制和抑制寄生模式的方法；完善了回旋行波管的非线性理论模型，并考虑了磁场和波导半径渐变、速度零散、波导损耗等因素对注-波互作用的影响；详细分析了发射损耗、相位稳定性等回旋行波管的大信号特征，为回旋行波管放大器的研制奠定了基础。

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。
