BAEPs and median nerve SLSEPs were studied in three groups of intracranial occupying lesions which were confirmed by cT and surgery.BAEPs and SLSEPs were abnormal in all the 16 patients with DTH(group A).Abnormal BAEPs(35 cases)and SLSEPs(33 cases)appeared in 36 supratentorial lesions with false location-definiting signs(group B).The major abnormality of BAEPs showed the delay of Ⅴ peak latency and Ⅰ~Ⅴ,Ⅰ~Ⅴ interpeak latency.SLSEPs mainly presented the abnormality of P(14)wave.Both BAEPs and SLSEPs were abnormal...

BAEPs and median nerve SLSEPs were studied in three groups of intracranial occupying lesions which were confirmed by cT and surgery.BAEPs and SLSEPs were abnormal in all the 16 patients with DTH(group A).Abnormal BAEPs(35 cases)and SLSEPs(33 cases)appeared in 36 supratentorial lesions with false location-definiting signs(group B).The major abnormality of BAEPs showed the delay of Ⅴ peak latency and Ⅰ~Ⅴ,Ⅰ~Ⅴ interpeak latency.SLSEPs mainly presented the abnormality of P(14)wave.Both BAEPs and SLSEPs were abnormal in 14 cases of posterior intracranial lesions with tonsillar hernia(group C).6 cases in group C were re-examined. The results indicated that BAEPs and SLSEPs may be used as an objective criterion in evaluating brainstem dysfunction of DTH an d n on-DTH patients.The tests of BAEPs and single SLSEP didn't have much significance in diagnosing tonsillar hernia,but the observation of the development of SLSEPs may be of great importance in the early diagnosis of the tonsillar hernia.

对CT和手术证实的三组颅内占位病变测试脑干听觉诱发电位(BAEP)和正中神经短潜伏期体感诱发电位(SLSEP)。16例病程中出现小脑幕裂孔下疝(DTH)的幕上病变,BAEP和SLSEP均异常。36例出现假性定位体征的幕上病变,BAEP异常35例,SLSEP异常33例。BAEP异常主要为v波峰潜伏期(PL),Ⅰ~Ⅴ、Ⅲ~Ⅴ峰间潜伏期(IPr)延迟;SLSEP以P(14),波异常及N(13)~N(20)IPL延迟为主。14例幕下病变所致的枕骨大孔疝,BAEP和SLSEP均异常,其中6例病程中复查了诱发电位。结果提示,BAEP和SLSEP可作为DTH患者脑干功能损害的客观指标,且可用于评价未出现DTH患者的脑干功能。BAEP和单次SLSEP测试对枕骨大孔疝的诊断意义不大,后颅窝病变进行SLSEP动态观察,对枕骨大孔疝的早期诊断有价值。

In the feild of Acoustic Emission(AE),the location problem is dealt as the one-dimen-tional liner location problem under normal conditions for engineering pipe. Because of thedisagreement of the theoretical analysis with practical circumstances,false location will cer-tainly be produced. For the source location problem with close relation to the process of thesignal propagation, the circumstance of the amplitude value and the energy spectrum of AEsignal were analyzed for engineering pipes, and the statements about the charateristic ofthem were made.In order to eliminate the affection of false location and raise the accuracvin AE detection,the regularity of the distribution about the false location was analyzed con-sidering the linear location questions on the given engineering pipes as an one-dimentinalproblem. The conclusions gotten in the theoritical aspect are as follows:as the positions ofthe source and two sensors which are not located in the same generatrix and central angle oftwo generatrix between them is increased, the time difference of false location is increasedand the position of false location is located in the direction of the sensor near the source. Thetest has been made to prove the correctness of the theoretical analysis in two kinds of engi-eering pipes.

对于工业管道,通常按一维问题进行线定位。由于理论分析与实际情况不相符合,必然产生伪定位。考虑到声源定位与其信号的传播过程密切相关,在工业管道上对声发射模拟源信号进行了幅值分析和能谱分析,论述了信号的幅值特性和能谱特性。为了消除伪定位的影响,提高声发射检测的准确度,对工业管道按一维线定位时的伪定位分布规律进行了分析。从理论上得到的结论为:当声源位置不在传感器所在母线上时,引起的伪定位时差随着声源所在母线与传感器所在母线之间的圆心角增加而增加,伪定位位置相对声源轴线位置偏向于相距它比较近的传感器一侧。在2种规格工业管道上进行了试验验证,试验结果与理论分析结论一致。

In all methods of passive location to get information of radiosource, direction finding cross location is more convenient and useful. But it has false location in environments of multi sources. In this paper, we use a spectral correlation theory in direction finding cross location to get rid of false location. Computer simulations show that this method is effective. [WT5”HZ〗

在用无源定位获取辐射源的位置信息的各种方法中,测向交叉定位方法是应用最多且较简便的一种方法。但该方法在空间存在多个辐射源的情况下存在虚假定位。本文将谱相关理论应用于测向交叉定位中,达到去除虚假定位的目的,模拟结果证实了用本文中的方法去除虚假定位的能力
