Latin influence in English entered English, or in what form. Some words have come into English from Latin more than once, through French or another Romance language at one time and directly from Latin at another. Thus we have pairs like fragile/frail, army/armada, corona/crown, ratio/reason, and rotund/round. The first word in each pair came directly from Latin, while the second entered English from French (or Spanish, in the case of "armada"). In addition, some words have entered English twice from French, with the result that they have the same source, but different pronunciations reflecting changing pronunciation in French, for example chief/chef (the former a
Electric discharge in gases the tube, either as a separate piece of material (e.g. nickel-63 in krytrons) or as addition to the alloy of the electrodes (e.g. thorium), to preionize the gas and increase the reliability of electrical breakdown and glow or arc discharge ignition. A gaseous radioactive isotope, e.g. krypton-85, can also be used. Ignition electrodes and keepalive discharge electrodes can also be employed. The E/N ratio between the electric field E and the concentration of neutral particles N is often used, because the mean energy of electrons (and therefore many other properties of discharge) is a function of E/N. Increasing the electric
