Several investigators have determined that placing the electrode parallel rather than perpendicular to the target nerve substantially increases the size of the lesion, thereby reducing the likelihood the treatment will miss or only partially coagulate the target nerve.234,235 After a literature review and cadaveric study, Lau et al.234 concluded the ideal electrode position is across the lateral neck of the superior articular process rather than the groove formed at the angle of the superior articular and transverse processes, as was used in most studies.159,160Other investigators have found the maximal lesion size to be reached within 60 s of lesion time,235–237 independent of whether the system is temperature or voltage controlled.238 Studies conducted in human myocardium have determined that irrigation fluid has either no effect or a slightly beneficial effect on lesion size.239 Hence, the use of LA to prevent procedure-related pain or steroid to reduce the incidence of neuritis184 should theoretically have no adverse effects on the efficacy of radiofrequency denervation.

一些研究者认为，将点击平行的置于目标神经比将其垂直置于目标神经增加了消融的范围，因而减少损伤可能使目标神经不被或部分被消融。Lau等回顾了文献中对尸体的研究，总结出理想的电极放置位置为上关节突颈部外侧而非常采用的上关节突与横突形成的沟。其他学者研究发现，不论系统是温度控制或电压控制，其最大的损伤范围都在60秒内达到。在心肌灌注的研究中，灌注液多损伤范围造成轻微或不造成损伤。因此，使用LA预防过程相关性疼痛或类固醇防止神经炎发生时，需理论上确保对射频消融效果无副作用。

We gained 3.3W green laser when we pumped the system at 25W power while the temperature of Nd: YVO4 was controlled at 22℃, LBO was at 18℃, the efficiency of light-light reached 14.3%, and the conclusion nearly come to the same thing with the theory, this result is better than the need to gain 3W green laser of industrialization, and surpasses it 10 percentage.

These theories respectively are the governing theory, liability-control theory and trust-deputize theory. The reason why we choose these theory to analyses the problem of incorruptible style supervision system construction of China customs is that the China customs, in theory, ignored the governing of bureaucracy, incompatible the liability-control, and the problem of asymmetry information. Because of the problem of concerning above, in reality, China customs should be appear the problem like feebleness of power of uprightness lead, weakness of superior supervision, catabolizing of polity power, the emptiness of same grade supervision, and failure of incorruptible supervision.

本文认为从这些理论视角出发，我国海关在理论上正是由于不重视科层之间的治理，责任控制无法相互对应，和委托代理产生的信息不对称的问题，而在实践中必然出现现行廉政监督机制的制度缺陷：垂直领导体制下的集权弱化，上级监督&虚监&问题；监督组织政治权威的异化，同级监督&弱监&问题；基层单位高度集权体制下的监督虚化，内部监督&漏监&问题；惩罚失当使腐败收益上升成本降低，廉政监督&失灵&问题等四个方面的弊端。
