用现代科学技术对中国古瓷的产地、年代和真伪进行研究一直是文博界和科技界研究的热点。本工作采用质子激发X射线发射(PIXE)分析方法研究了江西湖田窑明代中晚期青花瓷的胎、釉和青花中主量、微量元素的含量,并用质子扫描微探针(SPm)分析了青花瓷剖面的元素分布。结果表明:元素在古瓷的釉、胎和青花中的分布都是均匀的;胎与青花之间有5～10μm的中间层,青花与白釉之间无明显的分界线;制作青花的钴料可能产于江西、福建等地。

Contralateral inguinal exploration in children with unilateral inguinal hernia is still controversial. Only 20% of patients with patent processus vaginalis would develop a clinically apparent hernia [miltenburg Dm, nutctern JG, jaksic Tkozinetz CA. meta-analysis of the risk of metachronous hernia in infants and children. Am J Surg 1997;174:741- 4]. In 1999, our unit changed the practice of performing routine contralateral inguinal exploration of male children younger than 2 years and female children younger than 5 years to inguinal herniotomy of the symptomatic side only based on a metaanalysis published by miltenburg et al [meta-analysis of the risk of metachronous hernia in infants and children. Am J Surg 1997;174:741- 4]. We explored the contralateral inguinal area only in babies with a history of prematurity. methods: A prospective study of patients subjected to unilateral inguinal herniotomy from 1999 to 2001 was performed. Age, sex, side of the hernia, and incarceration at presentation were recorded. The incidence of metachronous inguinal hernia (mIH) and its risk factors were analyzed. The follow-up ranged from 36 to 72 months. Results: Of the 409 patients who presented with inguinal hernia, 264 underwent unilateral inguinal herniotomy. The rest were either children with bilateral inguinal hernia or premature babies who were offered bilateral inguinal herniotomy. Of these 264 patients, 180 (68% ) had right-sided inguinal hernia and 84 (32% ) had left-sided inguinal hernia. Fourteen (5% ) patients subsequently presented with mIH. Of these 14 patients, 8 were younger than 2 years at the initial presentation and 11 originally presented with left-sided inguinal hernia. no female child presented with mIH. Twelve (85% ) re-presentations with mIH occurred within 1 year of the original operation. Conclusions: The treatment of only the symptomatic inguinal hernia has not significantly increased the incidence of mIH. This evidence-based change of practice has avoided 1
