He told the AP that " the railgun is, for the moment, dead" .

" 轨道炮目前已经完蛋了。"

But Clark said the program experienced a number of problems, including the limited range of the railgun in testing.

但是克拉克表示，该项目遇到了许多问题，包括轨道炮在测试中的有限射程。

The railgun held the possibility of providing an effective weapon at a much lower cost than smart bombs and missiles.

轨道炮仍有可能用比智能炸弹和导弹便宜很多的价格提供一种有效武器。

But the barrel on tested railguns, Clark said, had to be replaced after about 12 to 24 shots were fired.

克拉克表示，但是已测试轨道炮的炮管在发射大约12到24发后就必须更换。

Using electricity, a railgun can fire a projectile at six or seven times the speed of sound, creating enough energy to destroy targets.

轨道炮利用电能可以以6到7倍音速发射弹丸， 产生足够大能量来摧毁目标。

After the ship was finished, the addition of a railgun in place of one of the 155 millimeter naval cannons was being considered for Lyndon B Johnson.

该船完工后，林登·B·约翰逊 (Lyndon B Johnson) 正在考虑添加一门轨道炮来代替其中一门 155 毫米舰炮。

Matthew Caris is a defense expert with the private advisory company Avascent Group. He told the AP that " the railgun is, for the moment, dead" .

马修·卡里斯是私人咨询公司Avascent Group的国防专家。他告诉美联社：" 轨道炮目前已经停止研发了。"

A normal gun can be fired about 600 times before the barrel has to be refurbished. But the barrel on tested railguns, Clark said, had to be replaced after about 12 to 24 shots were fired.

在必须翻新炮管之前，普通炮可以发射大约 600 次。但克拉克说，经过测试的轨道炮上的炮管在发射了大约 12 到 24 发后必须更换。

In the near future we may have new tech, like, space elevators and railgun launchers shooting trash deeper into space and having it be cheaper than ever, but until that day, people, we may just have to recycle.

在不久的将来， 我们可能会有新技术， 比如太空电梯和轨道炮发射器将垃圾发射到更深的太空，并且比以往任何时候都便宜， 但在那一天之前，人们，我们可能只需要回收利用。
