1瓷片中β剂量的积累和衰减研究显示文摘研究了β剂量在瓷片中与深度变化的关系.这个关系是β剂量在瓷片中积累和衰减作用引起的.与瓷器热释光测定年代有关的是积累深度和积累饱和值.实验结果表明,在深度80μm处,积累饱和值为1.05.由此推算出厚度为100μm的瓷片因积累而增加的平均剂量为4%,当厚度为200μm时仅增加2%,当厚度为30μm时平均剂量减少2%.由此可见,用这样厚度瓷片测定年代积累作用可以忽略.王维达 周智新 夏君定 梁宝鎏 Stokes M.J 1995核技术1995,18,8:11
2细粒石英前剂量方法显示文摘分析了前剂量技术的三种测量方法──多次激活、加剂量法和钉子技术的优缺点,并对细粒石英前剂量方法进行了专门研究.结果表明,细粒石英方法不仅简便,而且减少了多次激活、试验剂量和归一引起的误差,使最小可测年龄降至几十年.梁宝鎏 Stokes M.J 王维达 周智新 1995核技术1995,18,8:7

5接受赠卵患者延迟孕酮补充开始时间直到受精日未影响周期结局:一项随机研究显示文摘Objective: To determine whether the initiation of P supplementation as artificial luteal phase support (day- 1, day 0, or day + 1 of egg donation) in extensive programs of ovum donation influences cycle cancellation, pregnancy outcome, and implantation rate in day 3 embryo transfers. Design: Prospective randomized trial. Setting: Oocyte donation program at the Instituto Valenciano de Infertilidad, Valencia, Spain. Patient(s): Three hundred recipients with normal ovarian function, absence of uterine anomalies, and undergoing their first egg donation were recruited between September 2003 and September 2004. Intervention(s): A computer-based randomization divided the recipients into three groups when hCG was administered to their matched donors. The first group (group A) started P supplementation the day before oocyte retrieval; the second group (group B) started P supplementation on the day of the oocyte retrieval; and the third group (group C) started P supplementation 1 day after the egg retrieval once fertilization was confirmed. Main Outcome Measure(s): Implantation, pregnancy, and ongoing pregnancy rates were the primary outcome measures considered. The secondary outcome measure was the cancellation rate, especially due to fertilization failure. Result(s): Global cancellation rate and cancellation rate due to fertilization failure were significantly higher in group A (12.4% and 8.2% , respectively) than in group C (3.3% and 0% , respectively). Reproductive outcome was similar in all the groups except for a higher biochemical pregnancy rate in group A (12.9% ) than in groups B (6.6% ) and C (2.3% ). Conclusion(s): Initiation of P on day + 1 of embryo development decreases cancellation rates of day 3 embryo transfers in extensive programs of ovum donation without any deleterious effect on pregnancy outcome or implantation rate.Escribá M.J Bellver J Bosch E. 张旸 2006世界核心医学期刊文摘(妇产科学分册)2006,0,11:2
6柱形夸克-胶子等离子体演化源的π干涉学分析显示文摘本文对Bjorken柱形夸克-胶子等离子体演化膨胀源进行了2π Hanbury-Brown-Twiss(HBT)干涉学分析.利用量子几率振幅的路径积分公式计算2π HBT关联函数并得到对膨胀和静态源的HBT半径.研究发现,在冻结发射情况下的HBT半径要明显大于没有考虑多重散射吸收情况下的结果,源的膨胀速度导致HBT半径变小.对相变温度宽度为零的Bjorken柱形源,膨胀速度的影响要小于对应的球形源的结果.Efaaf M.J 张卫宁 KHALILIASR M 霍雷 金恩培 张景波 2005高能物理与核物理2005,29,5:2
