To evaluate the interaction effects of the three chemical components, Cochinchinenin A, Cochinchinenin B and Joureirin B, of dragon's blood resin, a new method of isobologram on the basis of the Loewe Additivity was established and could analyze the interaction effect of the three drugs with variable potency rations. By using this new method we assessed the interaction characteristic of the combined inhibition effects of three chemical components of dragon's blood resin on the evoked discharges of wide dynamic range neurons of spinal cord in rats.

为了评估龙血竭的3种化学成分剑叶龙血素A、剑叶龙血素B和龙血素B在活体动物实验中的相互作用特性，从经典的Loewe Additivity模型中推导出了在效价强度比变化的情况下判断3种药物的相互作用性质的等效图分析方法，以此分析了龙血竭的上述3种化学成分联合抑制大鼠脊髓背角广动力范围神经元诱发放电频率时的相互作用类型。

Results showed that Aha logogriphs elicited a more negative ERP deflection than did No-aha logogriphs in the time window within 1400-1700 ms (LNC1), 1700-2000 ms (LNC2) and 2000-2500 ms (LNC3) after onset of the logogriph. Dipole analysis localized the generator of LNC1 in the left Gyrus frontalis superior, LNC2 in the left frontal cortex and LNC3 in the posterior cingulate cortex.

This reduces the impact of a short circuit and assures that the bus does not conduct current through the aircraft. A Manchester code is used to present both clock and data on the same wire pair and to eliminate any DC component in the signal (which cannot pass the transformers). The bit rate is 1.0 megabit per second (1 bit = 1 μs).

该结构可以削弱短路对总线的影响并保证总线不会传导在航空器中流转的电流。1553总线用曼彻斯特码表示导线对上的时钟信号和数据信号，这可以去除信号中的直流成分，因为直流成分不能通过变压器。1553总线的波特率是1兆位每秒，即每微秒传输一位信号。
