Background: The neuron death resulting from traumatic brain injury can be classified into 3 types:(1)neuron death due to primary injury;(2)neuron necrosis due to secondary injury such as hemorrhage, compression, anoxemia and ischemia;(3)neuron apoptosis due to inflammatory factor, cytokine,, excitatory transmitter, Ca~(2+) overload and oxygen radical et al.

引言创伤性脑损伤所致的神经元死亡主要有三种：①原发性损伤所致的神经元直接死亡；②外伤后出血、压迫、缺血缺氧等继发性损伤因素所引起的神经元坏死；③炎性介质、细胞因子、兴奋性递质、Ca~(2+)超载、氧自由基等因素所诱发的神经元凋亡。

It is also indicated that decreasing either the apex angle of transmitter or receiver makes the detecting of the weak scattering more difficult while other parameters remain the same.

而增加发射机的发散角则基本不影响接收到的信号功率。在其他参数不变的情况下，增大接收机或者发射机的仰角都减小了接收机的探测到的信号功率。

Decreasing the apex angle appropriately of the transmitter helps the signal detection when the scattering angle remains unchanged.

计算结果还表明，在散射角和传输距离一定的情况下，适当地降低发射机的仰角可以提高接收机探测到的信号功率和信噪比。
