In the many factors that influence the quality of CdS deposition, the surface roughness of substrata is the important one. Exactly, SnO〓/glass substrata are the best, the glass substrata are the better, and ITO/glass substrata are not good for deposition of CdS polycrystalline thin films.

值得一提的是，沉积在ITO玻片上的CdS膜多呈六方相，而沉积在玻片上的CdS膜多呈立方相：然而，采用真空蒸发法制备的CdS薄膜，无论衬底是玻片，还是ITO玻片，其沉淀相均为六方相。

In order to understand the growth law of oil-tea camellia seedlings and to take technical measures to breed, the paper made a comprehensive study of the seedling height, ground diameter and leaf number of oil-tea camellia under four kinds of nursery substrata, and of the difference of growth increment between the different nursery substrata.

为了掌握油茶苗木的生长规律，便于采取科学合理的育苗技术，研究了在4种不同育苗基质条件下，油茶幼苗苗高、径粗、叶片数的生长规律，分析了4种育苗基质对油茶生长量的增加是否存在显著性差异。

In research area, the widely varying substrata has the thin effective thickness, low permeability, scattered distribution and obvious heterogeneity .Controlled by sedimentary facies, it has obviously corresponding relationship with the sedimentary facies. For this reason, substrata with thick effective thickness have better permeability.

研究区二类油层小层有效厚度和渗透率比较低，分布零散，变化比较大，非均质性很严重；受沉积相控制，二者之间有明显的对应关系，一般情况下，高的有效厚度带往往具有较高的渗透率。
