1993年3月23日,浙江省平阳县水头镇专业户温某收到一书籍邮包,怀疑有异,遂交由公安机关处理。邮包内为一本李时珍著《本草纲目》上册。分析书内可能装有爆炸装置。采用枪击破坏电源的方法拆除,其步骤是:1.确定是否为爆炸物。称可疑书本重量为2075克,而同类书本重2240克,两者差异明显。再用X光透视,发现内有电池、小手电、电线、雷管等物,布置有序,因而确定书本内是自制的爆炸装置。2.进行扫描拍片固定,分析爆炸装置线路、炸药的种类。通过仔细观察扫描照片,发现爆炸装置中还有2只电路板,其作用可能是打开书本封面时,电路自动接通,启动雷管引爆,或断开电路启动雷管引爆。同时,通过研究照片中的阴影,分析判断炸药种类可能属于硝胺成份。3.确定拆除方案。经对用水浸泡、刀割、枪弹打击电池等方案反复论证,认为枪击电池毁掉电源的方法具有安全、对物证破
On March 23, 1993, Wen Shuang, a professional resident of Shuitou Town, Pingyang County, Zhejiang Province, received a book parcel of doubtful suspicion that he was handed over to the public security organ for handling. Inside the parcel for a Li Shizhen “Compendium of Materia Medica” on the book. Analysis of the book may contain explosive devices. The use of guns to destroy the power of dismantling, the steps are: 1. To determine whether the explosives. Said the suspicious book weighs 2075 grams, and 2240 grams of similar books, the difference between the two obvious. Re-X-ray and found that there are batteries, small flashlight, wires, detonators and other objects, arranged in an orderly manner, and thus determine the book is made of explosive devices. 2. Scanning film fixed, analysis of explosive device lines, explosives types. Through careful observation of the scanned images, it was found that there were two circuit boards in the explosive device. The function may be that when the book cover is opened, the circuit is automatically turned on, the detonator is started, or the circuit is started to detonate. At the same time, through the study of the shadow of the photo, the analysis to determine the type of explosive may belong to nitramine composition. 3. Determine the demolition program. After immersed in water, knife cutting, bullets hit the battery and other programs repeatedly demonstrated that gunshot batteries ruined the power supply method has the safety of evidence of broken
