质子既然是恒星辐射的引力子聚合而成，它在空间不能绝对静止而是具有"群速"，恒星在空间的"宇宙速度"是"群速"的最大值，在原子内部，质子之间的相对速度同样可能达到这一速度。

By systematically analyzing the single particle level and the occupation probability near the Fermi surface,and the rule of nuclear particle number deviations with proton numbers for N =8,20,28,50,82,126 neutron chains within the relativistic mean-field model with BCS theory,we have discussed the stability of the shell structure for the traditional neutron magic in the whole range of nuclear spectrum from neutron line to proton line,and predicted that traditional neutron magic number effect shall possibly disappear only in light neutron-rich nuclei.

在考虑了BCS理论的相对论平均场模型框架内，通过系统研究 N =8，20，28，50，82和126六条同中子素链中每个元素费米面附近的单粒子能级间隔、粒子数占有概率比以及原子核体系的粒子数偏离随质子数的变化规律，讨论了传统中子幻数的壳结构在从中子滴线区到质子滴线区整个核谱上的稳定性，预言只有在轻核的丰中子区域，传统的中子幻数效应才可能消失，并把计算结果和最近的文献报道作了比较。

In this study, we evaluated the efficacyof preanesthetic proton pump inhibitor (PPI; oral rabeprazol)use in patients receiving regular H2-antagonisttherapy for more than 4 wk. Forty-eight patients with assumedcomplete tolerance to H2 antagonists undergoing elective surgerywere recruited and randomly assigned to receive either a preanestheticPPI (rabeprazol 20 mg; n = 24) or H2-antagonist (H2 group; roxatidine75 mg; n = 24) at 9:00 pm on the day before surgery and 2 hbefore the induction of anesthesia.

本次研究，作者评价了长期规则使用氢离子拮抗剂（口服法莫替丁，疗程大于4周）治疗的病人，麻醉前使用质子泵抑制剂（ PPI ；口服雷贝拉唑）的有效性。48位择期手术的病人假设能够完全耐受氢离子拮抗剂，随机分为两组，一组接受 PPI （口服雷贝拉唑20mg ； n ＝24），另一组接受质子泵抑制剂（口服罗沙替丁75mg ； n ＝24），服药时间分别为，术前一天晚上9点和麻醉诱导前2小时。

So, primary proton event can be identified effectively from the hybrid experiment results by use of ANN (with less dependence on interactive model), and a ideal primary proton energy spectrum will be obtained.

因此，ANN方法对模型的依赖性较弱，预计利用这一方法可以有效地分辨出联合实验中的原初质子事例，从而得到一个理想的质子原初谱。

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
