脉冲追踪法试验的具体原理和操作步骤？

       In biochemistry and molecular biology, a pulse-chase analysis is a method for examining a cellular process occurring over time by successively exposing the cells to a labeled compound (pulse) and then to the same compound in an unlabeled form (chase).

       protocol:

       --- Starve the cells--- Pulse chase with 35-S-Met or Lue for 5-30 min.--- Chase with “cold” Met or Lue.--- By the end of pulse (0 time), collect samples in a time course, lyse the cells, perform immunoprecipitation and autoradiography.

       这是老师课件上关于脉冲追踪的全部内容，我没听讲，看不懂是怎么回事

一个月加一个永 是什么字？

       两者有时通用，请看例子：

       1."In radar, the signals used are pulses."

        "在雷达中,使用的信号是脉冲。"

       2.

        Electroencephalography: Technique for recording electrical activity in the Brain, whose cells emit distinct patterns of rhythmic electrical impulses."

        脑电图记录法:记录及解释脑电活动的技术。脑的神经细胞能产生有节律地起伏的电脉冲。

       3."Impulses travel along the central auditory pathway from the cochlear nerve to the medulla to the cerebral cortex. Hearing may be impaired by disease, injury, or old age; some disorders, including deafness, may be congenital. "

        脉冲沿着中枢听觉通路前进,从耳蜗神经由延髓到大脑皮质。听觉可能因为疾病、受伤或年老而受损;有些听觉障碍如耳聋,可能是天生的。

       4."It is transmitted as electrical pulses of varied lengths or analogous mechanical or visual signals, such as flashing lights."

        电码发送的形式是不同长度的电脉冲,或相似的机械式信号,或可见信号(如闪光)。

       5."It works by converting the sound waves of the human voice to pulses of electrical current, transmitting the current, and then retranslating the current Back to sound."

        它将人们声音的声波转换成电流脉冲,传送这种电流,然后再把它翻译回到原来的声音。
