可发射的

After learning of Hertz's work in 1894, Marconi quickly realized the possible application.

马可尼在1894年了解了赫兹的工作后，他很快就意识到了可能的应用。1895年末，他建立了发射器和接收器，并且让成功地在2.5公里内传送了无线信号。1901年，他改进了这项技术，实现了横跨大西洋传输信号。

To increase the accuracy, the missile nose cone, 1.5 tons in mass, was made separable during flight.

为了提到精度，1.5吨的导弹弹头可在飞行中与弹体分离。R-2的射程有590千米，发射质量为20.3吨。1951年，第二套导弹系统进入苏军服役。

L Transmitter and receiver is used in pairs in the same channel, and it is also allowed to use in one-many way in the same channel (one transmitter sends signal, several receivers receive in the same channel; it is synchronous and accurate to receive, which is equal to wireless video distributor), or it is also allowed to use in the many-many way (one transmitter occupies 1 channel, and supports 4 channels of video and audio transmission at the very most, which causes no cross fire one another).

l 发送器和接收器在同一信道内成对使用，也可在同一信道内以一对多方式使用（一个发送器发送信号，同一信道内多个接收器接受信号，实现同步精确接收，作用与无线视频分配器等同），或以多对多的方式使用（一个发射器占据一个信道，最多同时支持4信道的音频视频传输，互相不影响）。

But only those that are travelling at a near-perfect right-angle to the surface of the hot material can escape and travel outwards.

但只有那些运动方向与发热材料表面成近乎完美的直角的光子可逃逸材料表面而发射出来。

The greater Eagle emission nebula, tagged M16, lies about 6500 light years away, spans about 20 light-years, and is visible with binoculars toward the constellation of Serpens.

老鹰星云及其周围的发射星云合称为M16，大小约为20光年，距离我们约有6500 光年远，用双筒望远镜可在北天的巨蛇座内找到它。

It's quiet an interesting place, only 15 minutes way from the space rocket station.

那儿可真是一个有趣的地方，离火箭发射站只有15分钟的路程。

There be an interesting place and leave rocket blast-off a station to only have the road for 15 minutes.

那儿可真是一个有趣的地方，离火箭发射站只有15分钟的路程。

The presacral haemostatic thumbtack projector is more quickly and has better therapeutic effect than tradition thumbtack in controlling presacral bleeding, and this new appliance could be used and advocated in clinic step by step.

使用骶前止血钉发射器对骶前大出血的止血速度比钉堵法快，止血效果好，是一种临床上可逐步应用与推广的新型止血器械。

For precision azimuth, as in gunfire control, a double-lobe pattern (figure 3) can give great directional precision by finding the direction in which the echo "pips" for both lobes are of equal heights. This is called "lobing".

当需要精确的方位角，如指挥火炮时采用双波瓣发射，两波瓣回迹强度相等时便可获得精确的目标方位角，这被成为&波瓣法&。

The absorption maxima and emission maxima didnt change obviously between the five-membered compounds when N-methyl as the bridge atom. The value of extinction coefficient was increased obviusly compared naphthalimide with naphthalic anhydride.

甲基化氮为桥原子的五元化合物之间最大吸收和发射波长相差不大，萘酰亚胺的消光系数比萘酐增加明显，loge最大相差可达0.45，荧光强度也略有增加，相差0.1左右。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
