The resistor (R) is used to limit the current through the diodes (D1 and D2).
电阻器（R）用来限制流过二极管（D1和D2）的电流。
The resistor (r) must be large enough to limit the current through the diodes to prevent damage to the diodes.
电阻器(R)必须足够大，以限制流过二极管的电流，使之不会损坏二极管。
The video conference system also has some shortages such as its lack of managing functions and limit on user numbers, so the further R&D is required.
但本系统会议管理功能较简单，由于硬件限制，支持的用户数量也有限，还需要做进一步的研究和开发。
Try to limit your pets to outside of the bedroom because their movements will keep with your body from fully relaxing into deep r.
不要让宠物呆在你的卧室内，因为它们的小动静会干扰你从身心放松的状态过度到深度R。
Through check, it is found that minimum excitation limit is calculated in P-Q plane, while impedance type loss-of-field protection is analyzed in R-X plane.
“发电厂并网运行安全性评价”要求验证低磁励限制与失磁保护的整定关系，在实际校核中，发现低磁励限制是在P-Q平面进行计算的，而阻抗型失磁保护是在R-X阻抗圆平面进行分析的。
