发射器

Absolute frequency stabilization of diode lasers of wavelength nm grade are reported using the modulation transfer method .

阐述了利用调节及转换技术稳定激光二极管发射器的频率，这种发射器可以发射纳米波长的激光。

Under the high frequency vibrating action, the crystal grain formed on the surface of the crystal nucleus eradiation equipment would be broken and peeled off, thereby ejected to zinc molten pool continuously and served as crystal nucleus source of equiaxed grain during solidification.

结果表明，当一种带有冷却结构且进行高频振动的晶核发射器插入锌液内时，锌液在晶核发射器表面迅速形核且长大，在高频振动作用下表面形成的晶粒将被折断剥离，从而连续不断地弹射到锌液中，成为凝固过程中形成大量等轴晶的晶核来源；采用带有水冷和气冷结构的晶核发射器对锌液进行振动激发形核处理后，锌凝固组织中的等轴晶率可分别提高到65%和80%。

This material can make some man-portable launcher reusable when it is formed on the inner surface of the launcher.

这种涂料成型于某型号便携式火箭发射器内表面后，与发射器粘接优良，可使发射器实现多次重复使用。

The majority of PzB 39 anti-tank rifles were converted to grenade launchers - Granatbüchse Model 39 (GrB 39). GrB 39 was a PzB 39 converted to take the standard rifle attachment grenade launcher able to fire standard hollow-charge anti-tank or anti-personnel grenade.

多数的PzB 39 反坦克枪被改造用于做为榴弹发射器，称为（Granatbüchse Model 39 ）GrB 39榴弹发射器，GrB 39 榴弹发射器就是用标准的枪口附加榴弹发射器改造而成，发射反坦克或人员杀伤榴弹。

The hardware system comprises a football locating emitter, a site corner orientation emitter, a vidicon, a radar velometer, a player locating emitter and a site vibration receptor. The software system comprises a plenty of computer program software developed for aiming at the hardware.

其中硬件系统由足球定位发射器、场地边角定向发射器、摄像机、雷达测速器、球员定位发射器及场上裁判振动接收器等组成；软件系统则由针对以上所述硬件进行开发的各种电脑程序软件等构件组成。

In this paper,the design thinking and working principle of the modeling missile launcher with balanceable launch principle is put forward.

文中提出了平衡式模拟导弹发射器的设计思想和工作原理，设计了一种可发射300mm 口径模拟导弹发射器。

On the contrary, when the balcony door is closed, sensor A and transmitter B remerges,then transmitter B emits signal to the receiving controller C,at that moment,air-conditioner works normal again for the loop of two-way valve connects controlled by circuit switching.

反之，当阳台门关闭，感应器A、发射器B重新合并，发射器B发射信号至接收控制器 C，通过电路转换控制二通阀回路接通，空调恢复正常工作。

The batteries on the "pingers," little electronic noisemakers stuck to the sides of the flight data recorder and the cockpit voice recorder, will start to wear down in about three weeks, and slowly fade to silence.

在装有飞行数据和驾驶仓对话录音的黑盒子两侧存在一个声波发射器，但是声波发射器上的电池将会在3周后减弱，直至声波发射器慢慢降到无声。

The transmitter has a physical layer transmitter for receiving data, formatting the received data into packets transmitting the packets and retransmitting packets in response to failure to receive a corresponding acknowledgment for a given packet; an acknowledgment receiver for receiving the corresponding acknowledgment; and an adaptive modulation and coding controller for collecting retransmission statistics and adjusting the particular data encoding/modulation using the collected statistics.

该发射器处的一物理层发射器是接收数据且将该接收到的数据格式化成具有一特殊编码/数据调制的数个分组。该物理层发射器包含n个信道，以发所述分组及相应未接收到相对应一给定分组的一相对应确认信息而再次发送分组。该发射器中的一适应性调制及编码控制器是收集再次发送的统计且使用该收集到的统计来调整该特殊编码/数据调制。该接收器具有一物理层n-信道接收器，以接收所述分组。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
