disk diameter
2.The density of the fibers is 7.78×103kg/m3, which was measured by Archimedes method. For a PLZT fiber/epoxy 1-3 composite disk with a diameter of 4.4mm, a thickness of 43μm and ceramic volume fraction of 0.7, its piezoelectric coefficient d33 and electromechanic coefficient kt are 410pC/N and 0.631, respectively.
4.The main results are summarized as follows:The large disk-shaped bulk specimens of nanocrystalline metals silver (nano-Ag),with a diameter of 80mm, thickness of 7.8mm,as well as an average grain sizes of 50nm, respectively, were successfully synthesized by an inert gas condensation and in-situ warm compacting technique (IGC) in our home made apparatus.
7.Operated in a wall-jet configuration, a 300-μm diameter carbon-disk electrode was used as the working electrode, which exhibits a good response at +0.90 V (vs. saturated calomel electrode) for four analytes. Under the optimum conditions, the analytes were baseline separated within 20 min in a 50 mmol/1 borax buffer (pH 8.7).
8.An average output power of 1.52 kW is obtained from two disks with a diameter of 40 mm and a thickness of 1.3 mm. The pumping peak power on each disk is 17.7 kW with duty cycle of 10%. The optical efficiency of the laser system is about 43% and the electrical to optical efficiency is more than 20%.
9.Epicatechin, rutin and quercetin could be base-line separated in a 50mmol/L borax buffer(pH8.5)within 12min. A 300μm diameter carbon disk electrode was used as the working electrode positioned carefully opposite the outlet of the capillary in a wall-jet configuration at potential of 0.95V(vs. SCE).
10.3-D dynamic finite element method analysis confirms that the rise time and stress level of the stress impulse as well as the specimen diameter have a significant effect on the testing result of CCCD-SHPB(central cracked circular disk-split Hopkinson pressure bar)dynamic fracture test system,and the dynamic fracture toughness under different loading rates can be achieved by changing the rise time and stress level of the stress impulse.
