0 a hard, yellow-brown chemical element used in nuclear reactors to absorb neutrons and in various compounds that are important in manufacturing -- 硼（一种非金属化学元素，质硬，黄褐色，用于核反应堆中以吸收中子；其化合物在制造业中非常重要）
Thirty-five holes are drilled into the board in a grid pattern; each hole has a nickel-plated neodymium iron boron disc inserted into it.
Typically, for a p-n junction, phosphorus atoms are implanted on one side of an interface and boron atoms are implanted on the other.
Mineral imbalances like boron, iron, and salinity and sodicity, though localized, do cause substantial yield loss.
Species variability in boron requirement is correlated with cell wall pectin.
Dry matter production and boron concentrations of vegetative and reproductive tissues of canola and sunflower plants grown in nutrient solution.
Here we present our studies on harmonic generation from boron ablation, irradiated by a femtosecond pulse.
The developmental stage during which boron limitation causes sterility in wheat genotypes and the recovery of fertility.
The main pulse was focused onto the position 0.1 mm above boron target.
