Free bile acids and their succinyl derivatives without detector response are separated and detected by reversed-phase ion-pair chromatography with UV-absorbent counter-ion as ion-pairing probe. The samples give positive or negative peaks depending on their retention relative to the system peak and frontal peak which are governed by varying chromatographic parameters. The influence of organic solvent, concentration and nature of counter-ion and pH value on retention and detector response has been investigated...

The life (in charge/discharge cycles, or C/D cycles) of a impulse power capacitor used in advanced high technology gets longer and longer. It is impossible by using traditional life test method to test a capacitor life up to 10~8 to 10~(12) C/D cycles. In this paper, we try to introduce the accelerated life test method for impulse power capacitors. As well known, the life of a capacitor is related to some parameters of the capacitor, such as: (1) The charging voltage of the capacitor; (2)The voltage reversal; (3)The ringing frequency; (4)The repetition. rate and (5) The operation temperature of the capacitor. we'll first findout the relationship between the life of the capacitor and each paramter, and then give the formula used for the accelerated life test for impulse power capacitors.
