mercury ion造句

• The electrons collapse to the mercury ion and neutralizes it.
• Mercury ions interfered with proper operation of his cathode-beam relay.
• Mercury ions absorb a specific frequency of ultraviolet light.
• The first step reduces mercury ions to mercury metal.
• There is simply insufficient room on that face of the molecule to accommodate both a mercury ion and the attacking nucleophile.
• The electron-beam ion trap ( EBIT ) is able to produce and store 78-fold charged mercury ions.
• The mercury ions emit light at characteristic wavelengths, the relative intensities of which are determined by the pressure of the vapor.
• Free mercury ions can bind to metalloproteins, particularly those with cysteine residues, and can cause incorrect conformations resulting in function loss.
• As illustrated by the second step, the nucleophile cannot attack the carbon from the same face as the mercury ion because of steric hindrance.
• The second test, SERT-II, launched on February 3, 1970, verified the operation of two mercury ion engines for thousands of running hours.
• The scientists are building a second mercury clock and will perform experiments to determine how stray electric and magnetic fields and other environmental conditions alter the behavior of the mercury ion.
• To tune the laser, a single mercury ion, an atom with one electron removed, was cooled to a few thousandths of a degree above absolute zero, minimizing error-creating heat vibrations.
• However, once the arc has been established, it cannot be stopped by grid action, because the positive mercury ions produced by ionisation are attracted to the negatively charged grid and effectively neutralise it.
• Krypton is the buffer gas used in conjunction with the mercury which is used to moderate the momentum of collisions of mercury ions in order to reduce the damage done to the electrodes in the fluorescent lamp.
• The mercury ions are attracted towards the cathode, and the resulting ionic bombardment of the pool maintains the temperature of the " emission spot ", so long as a current of a few amperes continues.
• Subjecting the tube to asymmetric waveforms, where the total current flow through the tube does not cancel out and the tube effectively operates under a DC bias, causes asymmetric distribution of mercury ions along the tube due to cataphoresis.
• On August 14, 1996, Wetterhahn, a specialist in toxic metals, was studying the way mercury ions interact with DNA repair proteins, and was using dimethylmercury as a standard reference material for 199 Hg heavy metal, cadmium.
• Since the mercury ion contains two atoms and has a total charge of 2 +, each atom has a charge of 1 +, making it mercury ( i ) .-- talk ) 19 : 21, 28 April 2010 ( UTC)
