A quasi-continuous mode of operation is realized for a plasma source of light utilizing a magnetically fixed discharge with the glow duration of 0.2 s.
In the case of a microwave pulse duration of 0.1-50 μs and off-duty factor of no less than 200, the pulse output power reaches ~1.3 W (in the continuous mode, it is ~0.3 W).
A high-current nanosecond generator with a peak power of up to 4 GW, an output voltage of 0.4-1 MV, a pulse duration of 8-10 ns, and pulse repetition rates of 300 Hz in a continuous mode and up to 1 kHz in the burst mode is described.
A pneumatic injector for periodic injection of fuel pellets into plasma of a thermonuclear facility in a continuous mode for an infinitely long time is described.
The cholinesterase sensors developed in his work can measure the concentrations of pesticides in a continuous mode for 8-12 h with the throughput of up to 5-6 measurements per hour.
An experimental investigation was made on the process of continuous ultrasonic copo- lymerization of hydroxyethylcellulose(HEC)with Poly(ethylene oxide)(PEO)in aqueous solution.The results show that the yield of the block copolymer(HEC-b-PEO)increases with the increase of ultrasonic intensity and the molecular weight of PEO and decreases with the increase of reaction temperature and reactant concentration.The degradation of the homopolymer and the recombination of the macroradicals formed during ultrasonic ...
Objective: To investigate some surgical techniques in dealing with a impending dropped nucleus when posterior capsular rupture during the phacoemulsification. Methods: The postoperative results of 18 cases (18 eyes) whose posterior capsular of lens ruptured with a impending dropped nucleus during the phacoemulsification were studied retrospectively. Three surgical techniques to prevent lens nucleus' fragments dropping into the vitreous cavity were applied. They are consecutive phacoemulsification with lower...
