一般要给出原始链接，比如来自 XXXXXXXXXXXXXXXX/a/w4OgF  First portable railgun

对于一些国家、地区或行业特有的规格或者术语，最好给出简单解释

使用“首个” 更好一点。。。

Capacitors are first wired in parallel with flexible busbars inside of a 3d-printed housing
电容器首先使用母线并联连接并且安装在3D打印的外壳中

Busbars were custom made and are flexible 4AWG equivalent.
自制的母线，等效于柔性4 AWG线材。

这里要提一下AWG这个东西，American wire gauge，美国线规。号码越小，线越粗。XXXXXXXXXXXXXXXXXXXXXXXX/wiki/American_wire_gauge

All 3 pairs of 2 capacitors.

The capacitor bank all wired up.
电容器组接线完毕

The railgun's electronics are based around an Arduino Uno R3 which monitors the capacitor voltage, amperage, temperature and battery voltage to ensure even charging and operation.
轨道炮的电气系统由Arduino Uno R3单片机控制。该单片机监控电容电压、电流、温度，以及电池电压，平衡电容充电和放电。

此处的'Even' 有平均的意思。

The 12V LiPo battery is first stepped up to 120V using a micro-inverter, then stepped up to 1550V through a transformer before being rectified.  The high voltage rectifier gets quite hot so a heatsink was mounted on the outside.
（前半段ok），整流器发热严重所以外面装了散热器。

The pressurized injector system sits directly below the electronics.
压力加注系统位于电气部分正下方

Moar wires.

根据urbanUictionary的结果（XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/XXXXXXXXXp?term=moar），主要意思是“更多的”，但是略带有失控的意思，此处可理解为没有好好规划，不计后果的暴力添加。

当然另一种可能的解释是原作手残，【more】

Attaching the handle which contains the pressure regulators.  The pnumatic system in the handle steps the CO2 down from a paintball tank into a compressed gas tank located in the center of the body.
安装手柄及调压阀。手柄中的气动系统将（尾部）彩弹枪（高压）钢瓶中的CO2减压到中间的气罐中。

The railgun is capable of firing copper plated tungsten, aluminum, carbon and teflon/plasma.  Here we have copper plated tungsten armatures.
在下对 teflon/plasma 表示不解。
到底是【铜镀钨】还是【钨渗铜】？？？

The injector system accelerates the armatures from rest in the breach loader to 100 m/s before contacting the rails.
估计原作者又手抖了，枪械相关没有'breach loader'只有'breech loader'，后膛炮。
这句话信息量巨大，需要些背景，译文也只能意译：
这款电炮分两部分，前半段电磁炮，后半段后膛炮。
[打击目标] <-------|炮口| ====== [电炮] ===||=== [后膛炮] =====|尾端|

加注系统在后膛炮中将弹丸从静止加速到100m/s，然后弹丸接触电磁轨道。

Another shot of the injector.
此处shot表示拍照。类似的screenshot就是电脑上的截屏。

After the first test, the pressure broke a steel bolt in the injector and a piece of weak 3d-printed PLA which held the bolt in place.  A new polycarbonate injector piece and nylon bolt plate were printed and the problem never happened again.
首测过后，发射压力损坏了加注器里的一个金属螺栓和一个强度不高的（3D打印，PLA塑料）螺栓固定件。后来使用聚碳酸酯（PC塑料）重新打印了注入器固定件并使用尼龙螺栓，问题解决并从未复发。

Painted.
喷漆。。。

The rails are designed to be removable.  They have a square exterior shape and a circular bore.
可拆卸的轨道，截面外方内圆。

The garrolite tube was wrapped in CF for additional strength.
原作再次手残，应为garolite
garolite这个词很“微妙”，wiki上说同等于“G10”，也就是玻璃纤维多层胶合板，和电路板的PCB属于差不多的东西。不是很明确FR4是否属于同一类。

The finished rails.  The rails consist of a set of outer and inner rails.  The outer rails are non-replacable and made of aluminum.  They never contact the armature so they never experience rail erosion.  The inner rails are copper and are designed to be periodically replaced.  They are held in place by the polycarbonate muzzle break and the polypropylene injector and are free to slide in and out once the muzzle break is removed.
【muzzle break】枪口制退器，此处当成枪口翻译没问题

CAD design of the railgun.  Everything in grey was 3d-printed.

请教一下，有人知道这个设计里面的电容型号是什么吗？想在我的设计里面参考一下他的一部分设计，但是苦于不知道选择哪个电容，图片又相对模糊一些，看不太清楚
