略论斯克里亚宾的晚期和声

斯克里亚宾晚期和声手法是我们研究欧洲19世纪与20世纪之交的音乐发展特点的重要内容之一。这一和声手法具有两个鲜明的特点，一是以个性化的“主和弦”彻底打破了传统调性和声的功能，二是强调和发展了三全音音程在音乐中的作用。     

Distribution of diatoms in the water and surface sediments of southern South China Sea

The relationship of species and abundance between the diatoms in the water and sediments from the southern South China Sea （SCS） were discussed, and the key environmental controlling factors were also investigated. Studies show that the diatom abundance is high in both water and sediments in the southeast part of the southern SCS and the varying trend is similar, while in the northwest part, the abundance is low, and the varying trend is different. The dominant diatom species are Thalassionema nitzschioides and Nitzschia bicapitata in water, and T. nitzschioides and Chaetoceros messanensis in sediments. The diatom species of small size and thin shell in water are more than in the sediments, while the diatom species of large size and thick shell in water are less. The percentage of species T. nitzschioides is higher in water of southeast part than in that of northwest part, but it is similar in sediments of both areas. It is shown that the southwest monsoon is the important factor influencing diatom abundance and T. nitzschioides percentage, and when the southwest monsoon is well developed, the distribution of diatom abundance and T. nitzschioides percentage are consistent in both water and sediments of the study area.     

长喙毛莨泽泻的胚胎发生

对长喙毛莨泽泻胚及胚乳的发育进行了研究。合子横向分裂成基细胞和顶细胞，基细胞不再分裂，顶细胞分裂形成胚体及合点端胚柄细胞。胚发育属石竹型。成熟胚为“Ｕ”形。胚乳发育属沼生目型，初生胚乳核在近合点端横向分裂，形成两个不等室，即合点室和珠孔室。
