In the current study, a series of cationic α-helical peptides of 20 a.a. were designed and synthesized based on four structural parameters, including charge, polar angle, hydrophobicity, and hydrophobic moment. Several methods were performed to describe the influence of these parameters on the antimicrobial and hemolytic activity, and on the permeabilizing effect on model membranes. The potential of these parameters to increase the antibacterial activity and to improve the prokaryotic selectivity is assessed.

On the base of large quantitative test, using coal petrography and organic geochemical data, the source of oil and gas in the coal-measures is analyzed. And it is concluded that the area's Yan'an group coal-bed has a low potential of oil production, and the oil and gas contained in the coal-measures and superjacent strata comes from underlying Upper Triassic Yanchang group strata. After a series of parameters of coal seam and surrounding rocks are tested, gas formation, storage, preservation, permeability of the coal-rock seam are analyzed and evaluated.

本文在大量测试工作基础上，利用煤岩学与有机地球化学资料，分析了煤系油气的来源，认为本区延安组煤系煤层生油潜力差，煤系及其上覆地层所含油气为下伏上三叠统延长组源岩所生，油气主要通过迭置的砂体、不整合面、构造裂缝等自下向上运移进入煤系；通过对煤层及围岩一系列物性参数的测试，分析与评价了煤岩层的生、储、盖、渗性能与可抽放性，得出主采4_(-2)号煤层属中等储集、低渗透层，围岩封闭性差，渗透性高，煤层瓦斯含量低，而顶板砂岩瓦斯含量高，为采面瓦斯涌出的主要来源。
