自动旋转

DTDS tail drive allows full tail control, including aerobatics, during auto rotation maneuvers.

DTDS 机尾驱动器允许完全尾部控制，包括在自动旋转中的特技飞行。

TILT ROTORCRAFT : An aerodyne which derives the whole or a substantial part of its lift for vertical or hovering flight by tilting rotor upward to a position substantially vertical, and in forward flight derives its lift from rotors and/or wings, and is capable of autorotation in the event of power failure.

倾斜旋翼飞机：一种旋翼机，垂直或悬浮飞行时，整个或其中相当一部分之爬升力源自倾斜旋转翼使上升到一个极度垂直的位置，而在向前飞行时，爬升力源自旋转翼和/或机翼，并有能力在发生动力供应中断时自动旋转。

Autorotation involves a controlled descent with the rotor in low pitch to keep it spinning.

自动旋转涉及与转子间距控制在低后裔保持它旋转。

During autorotation, they could simply rotate shut to close off air-flow through the engine and greatly reduce cold drag.

在自动旋转，他们可以简单地旋转，通过关闭，以关闭发动机的空气流动，大大降低了冷阻力。

The docile manners, however, ended at autorotation, an unpowered descent to landing that helicopter pilots practice in order to be able to respond in case of engine failure.

在驯服风度，但是，收于自动旋转，一无动力下降到着陆的直升机飞行员的做法，以便能够在发动机响应故障的情况下。

Objective The purpose of this study was to analyse the vestibular autorotation test results in patients with vertigo and disequilibrium and to evaluate rationality of VAT in clinical practice.

目的 分析眩晕及平衡功能紊乱病人的前庭自动旋转试验（Vestibular Autorotation Test， VAT）检测结果，探讨VAT的临床应用价值。

They conducted a large amount of test work with a view to evaluating the automatic engine control system, mastering single-engine piloting techniques and making engine-out landings in autorotation mode without a landing run.

他们进行了一项测试工作，查看大量的自动评估引擎控制系统，掌握单引擎驾驶技术，而且没有一个着陆滑跑使发动机在自动旋转模式来降落。

In order to improve the measuring accuracy and efficiency, a high accuracy inspecting system for measuring the centroid and centroidal deviation of bullets based on three point method is designed. The working principle, relevant calculation formulae and the measuring equipment for measuring the centroid and centroidal deviation of bullets are presented, and the main factors affecting measuring precision are discussed. Then, a multiple measuring platform with automatic leveling and column structure autorotation of 90° is put forward.

为了提高其测量精度和效率，设计了基于三点法的高精度弹丸质偏心测量系统，介绍了测量原理、计算公式和测量设备，分析了测量误差产生的因素，提出了一种多测试平台和自动调平以及弹体自动旋转90°的设计思想。

This milling machine has fixed cross-rail and column structure. The national patent technology "the new multiple guideway" and CNC universal milling head with AC axes(3axes +2axes) type are applied to it. It can realizes rotate index ±370o at AC axes. Equipped with domestic or imported CNC system and capability, the machine can realize pentahedron machining.

产品采用定梁定柱结构，刚性强；应用《新型复合导轨》国家专利技术和AC轴（3轴+2轴）型数控自动万能铣头核心技术，可实现AC轴±370o自动旋转分度；选配国产和进口数控系统，自动完成多种空间方向的加工，实现五面体加工功能。

Self-executing agency types include hydraulic, pneumatic and electric and so on, most of the automatic rotary valve can be electric and pneumatic actuator to operate.

自动执行机构的类型包括液动、气动和电动等，大部分自动旋转阀可以通过电动和气动执行机构来操作。

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。
