By using "Acupuncture Manipulation Information Analyzing System", the traditional reinforcing and reducing manipulations of acupuncture described in classical Chinese medical books were imitated and their parameters analyzed. It was found that in the oscillogram, the differences between the reinforcing and reducing manipulations (rapid-slow reinforcing-reducing skill, lifting-thrusting reinforcing-reducing skill) are the bigger duration of descending branch (t1) and smaller duration of ascending branch (t2) for the former, and shorter t1 and longer t2 for the later, due to slow insertion and rapid withdrawal of the acupuncture needle for the reinforcing, and rapid insertion and slow withdrawal of needle for the reducing. While for twirling reinforcing, t1 < t2 for predominantly-leftward twirling, and for twirling reducing, t1 > t2 for predominantly-rightward twirling were found. In addition, it is supposed that those parameters as the amplitude (s), frequency (f) and duration of one cycle (t) of the oscillogram may be related to acupuncture stimulating quantity, while t3 (duration of the plateau segment), t4 (duration of the horizontal plane segment) and their variance may be associated with the stability of the acupuncture manipulation. Due to the limited literal recordation, some other traditional acupuncture manipulations can not simulate indeed, because we don't know how to perform those kinds of acupuncture manipulation. This just reflects the importance of objectivity of acupuncture manipulations.
运用“针刺手法信息分析系统”，模拟中医古籍中记载的传统针刺补泻手法并分析其参数。结果发现，在示波图中，补法（徐疾补泻手法、提插补泻手法）与泻法的差异在于，补法时针尖向下行支持续时间（t1）较长，向上行支持续时间（t2）较短，这是因为补法进针慢、出针快；而泻法时针尖向下行支持续时间（t1）较短，向上行支持续时间（t2）较长，这是因为泻法进针快、出针慢。捻转补法中，以向左捻转为主时t1 < t2；捻转泻法中，以向右捻转为主时t1 > t2。此外，推测示波图的幅度（s）、频率（f）和周期持续时间（t）等参数可能与针刺刺激量有关，而t3（平台段持续时间）、t4（水平段持续时间）及其方差可能与针刺手法的稳定性有关。由于文字记载有限，一些其他传统针刺手法无法确切模拟，因为我们不知道如何操作这些针刺手法。这恰恰反映了针刺手法客观化的重要性。
