求高手来帮我翻译一下，谢谢啦

Electric strikes (also called electric latch release) replace a standard strike mounted on the door frame and receive the latch and latch bolt. Electric strikes can be simple to install when they are designed for drop-in replacement of a standard strike, although some electric strikes require that the door frame be heavily modified. Installation of a strike into a Fire Listed Door (for open backed strikes on pairs of doors) or Frame must be done under listing agency authority if any modifications to the frame are required (mostly for commercial doors and frames). Since there is no current Certified Personnel Program to allow field installation of electric strikes into fire listed door openings, listing agency field evaluations would most likely require the door and frame to be de-listed and replaced. Electric strikes allow mechanical free egress: As a user leaves, he operates the lockset in the door, not the electric strike in the door frame. Electric strikes can also be either fail unlocked (except in Fire Listed Doors, as they must remain latched when power is not present), as a mag lock, or the more secure fail locked. Electric strikes are easier to attack than a mag lock. It is simple to lever the door open at the strike, as often there is an increased gap between the strike and the door latch. Latch guards are often used to cover this gap.
Electric mortise and cylindrical locks are drop in replacements for the door mounted mechanical locks. A hole must be drilled in the door for electric power wires. Also a power transfer hinge[2] is used to get the power from the door frame to the door. Electric mortise and cylindrical locks allow mechanical free egress. Electric mortise and cylindrical locks can be either fail unlocked or fail locked. In the US, UL rated doors must retain their rating. In new construction doors are cored and then rated. In retofits, the doors must be re-rated.

Electrified exit hardware, sometimes called panic hardware or crash bars, are used in fire exit applications. One pushes against the bar to open it, making it the easiest of mechanically free exit methods. Electrified exit hardware can be either fail unlocked or fail locked. A drawback of electrified exit hardware is their complexity which requires skill to install and maintenance to assure proper function. Only hardware labeled "Fire Exit Hardware" can be installed on fire listed doors and frames and must meet both Panic Exit listing Standards and Fire listing Standards.

。电动罢工(也称为电动锁释放)取代标准的罢工安装在门框上和接收门闩和锁螺栓。电动罢工可以是简单的安装,当他们被设计为替代燃料标准的打击,尽管一些电动罢工要求门框是重大修改。罢工的安装到火上市门(开放支持打击双门)或框架必须下完成清单的代理权限如果任何修改。
