Dissociation and Coulomb Explosion of H2^4＋ in S^q＋ ＋H2 Collisions

We have investigated fragment emission from molecularions in H2^r collisions between S^q and H2 with incident energies of 12.5, 15.625, 18.75, 21.875, 25, 28.125, 31.25, 34.375, 37.5, 40.625, and 43.75 keV/u, respectively. The energy distributions of the fragments are measured by time-of-flight techniques. The experimental results show evidences for molecular Coulomb explosion and dissociation. A program[1] is estab-lished based on the Monte Carlo technique to simulate the time-of-flight spectrum of fragment ions with different initialkinetic energy in ion-Molecule collisions. Simulations are done for S^2 H2 collisions and compared with experimental results.

用N-(3-P)NEM标记毛发角蛋白研究毛发中低硫蛋白和高硫蛋白的状态

本文用一种特异性标记蛋白质巯基的N-(3-P)NEM为荧光探针标记毛发角蛋白,经SDS-PAGE后,通过荧光薄层扫描确定N-(3-P)NEM与含巯基蛋白结合的部位。结果表明,毛发角蛋白中的低硫蛋白分子量在45,000～63,000范围,约占总蛋白量的49.6％～68.2％;高硫蛋白分子量在4,000～20,000范围,约占总蛋白量的18.9％～36.2％。除低硫和高硫蛋白以外,毛发角蛋白中还可能存在一种极低硫蛋白,分子量位于22,000～32,000范围。对人与5种动物的毛发角蛋白组分进行比较,证实人与动物的毛发角蛋白的主要差异在高硫蛋白,不同种属的动物毛发角蛋白中低硫蛋白和高硫蛋白的含量也不相同。作者认为毛发角蛋白中含巯基蛋白的差异可为动物分类学和法医学在进行毛发比较鉴别方面提供新的重要信息。
