地球物理学报 , 2007,
Abstract: 针对两盘无明显断距的城市活动断层难以探测的实际问题,根据断层带电阻率特点,提出了电阻率横向剖面法,在物理模拟和数值模拟基础上,通过现场实际断层或裂隙带的探测结果证明:电阻率横向剖面对两盘无差异断层的探测和定位较常规剖面准确,解决了两盘无明显断距断层的探测问题.

Abstract: To solve the actual problem that urban active faults without obvious displacement are difficult to be detected, we propose the Schlumberger transverse profiling method based on resistivity characteristics of faults. Through physical and numerical simulation, the actual detecting results of site faults or broken zones show that the Schlumberger transverse profiling method can precisely locate and detect faults without large displacements, and the detecting effect is better than that based on regular profiling methods. Therefore, this method has solved the problem how to detect a fault without clear displacements on its both walls.

Abstract: In the three-dimension seismic data processing, displaying the post-stack seismic data of adjacent lines in the longitudinal direction may save plotting paper and reduce processing cost. The paper presents the seismic data processing method to create 3D seismic plotting data which can be displayed in the longitudinal direction. The method introduces that the drawing data set can be created by separating 3D post-stack data set, prolonging data record lengths, modifying the line number and merging 3D post-stack data set. Through real plotting, post-stack seismic sections of different lines may be displayed in the longitudinal direction. Therefore the processing method saves paper greatly and reduces processing cost.
噪声对自发脑电图功率谱的影响

Abstract: 自从六十年代前后,将电子计算机技术引进脑电图领域对脑电图进行功率谱[1],相关函数[2,3]、相干函数[4]和迭加平均[5]分析以来,对脑电图的研究取得了许多显著的进展,并引起极大的关注,但脑电图的计算机分析用在对噪声的研究之中尚属少见,众所周知,噪声对人体的影响是多方面的,其中对神经系统的影响是一个重要的方面[6,7]。我们过去的工作也曾发现80分贝(A)的噪声长期接触,可引起神经性症状的出现率增加5.2%,而95~100分贝的噪声使症状的出现率增加到17.3%,但是迄今未能找到一种客观指标,能够反映噪声对神经系统的这些影响,本文拟在这一方面进行某些探索,并希望能为制定噪声标准提供参考依据。

Abstract: 自90年实现实验室合成C60/C70以来,碳原子簇化学引起世界各国科学家的广泛兴趣,纷纷开展与其相关的各项研究。由电阻加热法、电孤法产生的烟灰经过甲苯(或苯)抽提便可得到C60/C70混合溶液,但其大量分离却很困难。

Abstract: 摘要: 目的??探讨及评价上尿路血尿患者CT尿路成像(CTU)检查阴性行输尿管软镜检查的临床意义,提高上尿路血尿患者的病因诊断率。方法?回顾分析该院收治的10例CTU检查阴性的上尿路血尿患者。其中,男7例,女3例,左侧上尿路血尿4例,右侧上尿路血尿6例。均行输尿管软镜检查进一步明确诊断并采取相关治疗措施。结果?输尿管软镜镜检发现3例肾盂肿瘤,1例为肾动静脉瘘,3例考虑为非特异性炎症,3例未见明显异常。结论?CTU检查阴性上尿路血尿患者行输尿管软镜检查对诊断有重要的临床意义。
Abstract: Objective?To investigate and evaluate the clinical significance of flexible ureteroscopy in computed tomography urography negative patients with upper urinary tract hematuria. To improve the diagnostic rate of patients with upper urinary tract hematuria.?Methods?We retrospectively reviewed the cases of 10 computed tomography urography negative patients with upper urinary tract hematuria. The age ranges from 38 to 75 years old, and the average of them is 45.2 years old. The patients consist of 7 male patients and 3 female patients. Among them, 4 cases were on the left upper urinary tract cases, 6 cases were right upper urinary tract. All patients received flexible ureteroscopy to confirm the diagnosis and take the relevant treatment.?Results?In the total of 10 patients, 3 patients (30%) were diagnosed with tumors of renal pelvis, a renal arteriovenous fistula was found in 1 case (10%), 3 patients (30%) were considered non-specific inflammation, other 3 patients (30%) had no obvious abnormalities. ?Conclusions?Flexible ureteroscopy has significantly clinical diagnosis in computed tomography urography negative patients with upper urinary tract hematuria.

宝石柱塞泵密封圈材料的研制

摩擦学学报 , 1982,
Abstract: 用于宝石柱塞往复平流泵的国产密封圈,寿命较短,直接影响了往复泵的使用和生产。 本文报导了一种寿命较长的NFF-16塑料密封圈的研制和应用结果。通过材料的摩擦磨损试验、溶剂浸泡试验、密封圈在往复泵中的长期应用试验,结果表明,主要组成为聚四氟乙烯/聚对羟基苯甲酸酯/石墨的复合材料,摩擦系数较低,磨损较小,对对摩面的磨损亦较小。密封圈的密封性能和抗溶剂性能良好,工作寿命可达1000~2000小时以上,满足了使用要求。
