The OSIRIS telescope is a Three Mirror Anastigmat consisting of conic surfaces: a concave hyperbolic primary, a convex parabolic secondary and a concave spherical tertiary.

OSIRIS 望远镜是一个三反射系统，由一个凹双曲面主镜，一个凸抛物面次镜和一个凹球面三镜。次镜 M2在中间，主镜 M1和三镜 M3呈离轴配置。

The system is composed of an off-axis Three-Mirror Anastigmatic telescope and two Offner convex grating spectrometers.

该系统由离轴非球面三反射镜望远成像系统和两个Offner凸光栅光谱成像系统组成，通过改变两个光谱成像系统的变倍比来实现两种探测器的匹配。

In order to meet the requirements of high space resolution, high spectral resolution, high time resolution, small volume and light weight for the remote sensing of pilotless planes, the off-axis three-mirror anastigmatic optical system is adopted.

针对无人机遥感要求高空间分辨率、高光谱分辨率和高时间分辨率且体积小、重量轻，采用离轴三反消像散光学系统满足其大视场轻量化设计要求。

Petals 5 or lacking, free or adnate to base of androecium, convolutely imbricate.

花瓣5或无，离生或贴生到雄蕊群的基部，旋转覆瓦状排列。

The measuring microphone shall be placed 5cm from the loudspeaker in an anechoic chamber, on axis.

测量麦克风应该在消声室里离喇叭5迷离的地方放置着，在基准线位置。

Objective To study the effects of local anesthetics on the activity of erythrocyte immunity in vitro.

目的：研究常用局部麻醉药对离体鼠红细胞免疫粘附功能的影响。

Methods 2000 women who desired to terminate pregnancy and operate artificial abortions without pain, were selected to anesthetize with propofol and fentanyl or propofol. The effect of analgesia and the extension degree of cervix were observed, and the time of anesthesia, the dosage of propofol, the time of operation, the time of patients to come around and leave hospital were recorded.

选择要求终止妊娠、自愿接受无痛人工流产术的妇女2 000例，应用丙泊酚复合芬太尼或丙泊酚静脉麻醉，观察镇痛效果、宫颈松弛程度，记录术中出血量、麻醉起效时间、丙泊酚总剂量、手术时间、苏醒时间、离院时间和人工流产综合征的发生情况。

We did spend most of the day snorkeling and just off shore I did get to see a turtle as well as triggerfish and angelfish.

我们白天大多数时间里都在浮潜，就离海岸不远，我有看到过一只海龟，还有触发鱼和天使鱼。

Install the unit on the wall 2.2 meters above the ground then adjust the angle of bracket to make the lens aim at the detection area, then insert the power plug to the socket and the LED2 indicator light will flash for each second.

报警器挂在离地面2米的墙上，调整万向节角度，使透镜对准监控场所，将电源插头插入市电插座上，LED2工作指示灯每过1秒钟闪亮一次，报警器延时一分钟后进入工作状态，此时布防后如有人进入警戒区域，步行指示灯(LED1)亮起，报警器发出刺耳的报警声音，响约60秒自动停止，停后约5秒自动进入布防状态。

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。
