In this thesis, several kinds of spherical curvature measurement methods are introduced, and the "arch-high and chord-length method" is selected after introduction of the existing methods, and then the novel type of instrument for measuring spherical curvature with the variable ring is developed. In research, the grating sensor, integrated circuits and other new technologies are adopted and integrated. As a result of this, Its specific technical indicator is 0.1um in absolute accuracy, 0.01% in relative accuracy, and 0.001% in repeat accuracy.

本文首先对几种球面曲率半径的测量系统进行了深入的理论分析，在分析了各个测量方法优缺点的基础上，选用了"弓高弦长法"的测量原理，并从理论上推导了本文所述系统的可行性，采用光栅传感器、集成电路等新技术成果，将机械、电子技术、计算机技术以及传感器技术有机结合，研制出一种新型的可变径球面曲率测量仪器。

CH3OH could attack the phosphor atom in 1,3,2-dioxaphopholane of compiound (1) to give O-methyl O-hydroxyethyl-O-phthalimidoethyl thiophosphate in 85% yield; in the presence of potassium hydroxide aryl selenol could attack the carbon atom in 1,3,2-diox-aphopholane of the cyclic phospholipid conjugate of N^1-(2-furanidyl)-N^3--5-fluorouracil to give the corresponding product of ring-opening in high yields.

在室温下，以异丙醇作溶剂，苯硒酚与化合物2不反应。在氢氧化钾存在下，以异丙醇／水作溶剂（体积比20：1，在室温下，硒酚可以有效地进攻中化合物2中1，3，2-二氧磷杂环戊烷中的碳原子生成相应的开环产物。按照这一反应条件，顺利实现了硒酚对N^1-（2-呋喃基）-N^3-羟烷基-5-氟脲嘧啶硫代环甘油磷脂缀合物的亲核开环，生成甘油骨架的端碳原子上带有芳硒基新颖的磷脂核苷缀合物。

电子商务是人类社会发展史上的又一次革命，在电子商务中，网上支付是其关键一环。只有实现了网上支付，才能进行真正意义上的电子商务交易，否则电子商务只能停留在网上信息发布与搜索、初步意向达成和草签协议阶段。而人们是否采用网上支付最主要考虑的因素就是安全。我国电子商务和网上交易近年来取得了较大的发展，然而也存在很多问题。其中网上支付正成为我国电子商务发展的瓶颈之一。影响网上支付发展的因素很多，可分为技术性因素和非技术因素。由于我国信息技术发展起步较晚，因此在发展网上支付方面存在一定的技术困难。
