银幕上的旋律流程--中国电影音乐创作浅谈

中国电影音乐的探索始自20世纪30年代至50年代直至60年代,中国电影音乐趋向成熟,交响曲的语言在电影音乐中运用极为普遍;而20世纪80年代至90年代的中国电影音乐已步入辉煌,在音乐所具有的时间上的连贯性和结构上的完整性把握得恰到好处,音乐的色彩和电影的色彩在大师级的作品中往往得到了完美结合。     

建筑物的改造与加固

建筑物的改造与加固是一项技术性和实践性很强的工作。设计方案制定前要重视资料的收集和分析。主要的加固措施是用高强度的材料与被加固的物体紧密连接以提高被加固体的强度,常见的方法有加大截面法、植筋法或碳纤维布粘贴加固法等。     

OPTIMAL SETTING-UP OF KNITTING ELEMENTS AND ITS EFFECT ON TENSION VARIATION

The dynamic yarn tension variations during knitting cycle are very difficult to control and be-come one of barriers to knitting on modern warp knitting machine.Examination of experimentaldata and theoretical analysis show that the relative position of spring rail to knitting elements suchas needle,guide as well as their displacement has noticeable effect on tension variation so that theknitting condition can be much improved by rearrangement of the knitting elements and theirmovement within a knitting cycle.

THE TRANSFER BEHAVIOUR OF SOME CATIONS AT WATER／NITROBENZENE INTERFACE BY SEMIDIFFERENTIAL CYCLIC VOLTAMMETRY

The transfer of Sr~(2+) and Ba~(2+) ion, facilitated by 18-Crown-6 present in the aqueous phase, and of succinylcholine ion at w/nb interface were investigated by semi-differential cyclic voltammetry. A good polarographic curve of succinylcholine ion dissolved in water was obtained in the system of 0.01 mol/l LiCl (w)——0.01 mol/l TBATPB (nb). The peak current is directly proportional to the concentration of SC~(2+) ion. It can be used for the determination of SC and the detection limit is 1.05×10~(-5) mol/l.The apparent D~w and D~(nb) have been estimated. The transfer of Sr~(2+) and of Ba~(2+) at the interface are facilitated by 18-Crown-6 present in the aqueous phase and the peak current is directly proportional to the concentration of 18-Crown-6 in water. This method can be used for the determination of the complexing agent and for the stability constant of the complex formed in the aqueous phase.All the experimental results are in keeping with the theoretical.
