Herein, a series of compounds, BP-C〓-NBD (n=2, 3, 4, 5, 6, 8, 10), was synthesized. Nanosecond flash photolysis, phosphorescence emission and lifetime, as well as photoisomerization reaction of norbornadiene were used to understand the intramolecular triplet energy transfer in detail.

我们设计、合成了以多亚甲基连接的二苯酮与降冰片二烯（BP-C〓-NBD，n=2，3，4，5，6，8，10）系列化合物，利用纳秒时间分辨技术、低温磷光发射、磷光寿命以及光敏异构化的方法，对其分子内三重态能量传递过程进行了详细地研究。

At first, this paper gives the brief introduction of the history and present status of accelerometer and its testing technology, the working principium and math model of the liquid floated pendu-lous accelerometer, and then, decides the binary width pulse force retrim loop as the design proposal of testing system, researches the transfer function of every part in the system emphasizly, analyses the stability of the whole accelerometer testing system from the angle of control theoretics by the open loop transfer function of system, and designed the correcting net, analyses the basal problems such as resolution, sampling restraint, precision and so on, designs the hardware testing circuits such as preamplification, band-pass filter, alternating amplifier, phase sensitive demodulatorn, pulse-width modulation, frequency scale circuit, moment current generator. Finally, using the graphics program language LabV-IEW which is designed for testing field especially by NI accomplishes the solfware design of testing system,realized the testing functions.
