Electron gun is accelerated electron bombardment of a target screen, the light emitting device which emits a certain energy, speed and angle of a beam and electron beam.

Introduction wire cutting molybdenum wire, wire cutting molybdenum wire protection, accelerator Tudou-0. Line cutting controller, molybdenum wire diameter of 0.14 4A current.

Organic molybdenum friction-reducing mechanism of lubrication and friction on the polished surface, the friction of the surface, the pressure in the high-load points, cutting-edge chemical promote, promote organic molybdenum decomposition of the MOS2 and certain phosphide , sulfides, nitrides, etc. These product was dispersed in an oil solvent adsorbed and deposited on the friction surface, molybdenum disulfide film is formed covering the anti-wear layer, so as to reduce friction, wear and lubrication.

Molybdenum element made of additives as a car engine fuel additives, may not be fuel efficient, but after the video shown to play a role in lubrication.

Base oil antifriction organic molybdenum additive effect its type, there is a direct relationship between dosage, sulfur, phosphorus organic molybdenum additive has better friction reduction; with dosage increases, the organic molybdenum antifriction additives effect increases; in the finished oil, organic molybdenum additive at 1.0% plus volume down, have shown very good friction reduction.

Molybdenum involved in plant nitrogen metabolism in vivo, and promote the absorption of phosphorus and transport, transport of carbohydrates also plays an important role. Crop molybdenum common manifestations are small plant, growth inhibition, leaf chlorosis, wilt resulting necrosis. Leguminous crops molybdenum, nodule dysplasia, tumor is small and less nitrogen fixation capacity is weak or unable to fix nitrogen, leguminous crops due for molybdenum have special needs, it is prone to the phenomenon of molybdenum, for molybdenum fertilizer should be applied in the first focus leguminous crops. Molybdenum in acidic soils, most likely, sandy soil molybdenum common than clayey soil. As the soil pH increases, the effectiveness of molybdenum increases.

To the untrained eye, it can be difficult to tell pure solid gold from fake gold, gold mixed with other metal, or cheaper metal plated with a thin layer of gold. Depending on the quality of the piece, the test can take just a few seconds using common household items, or may require additional materials to get definitive results. Test jewelry you're unsure of before getting costly appraisals, or just to confirm that the gold is pure.

1.Hold a magnet near the piece to test the attraction. If the object sticks to the magnet, it is not pure gold, but gold plate or another metal mixed with gold. However, if it doesn't stick to the magnet, it doesn't necessarily mean that it's real; more testing is required.

2.Rub the gold against a piece of glass (use a piece that isn't valuable, such as a glass plate from an unused picture frame). If it scratches the glass, it is not pure gold, since gold is a soft metal. If it doesn't leave a scratch, it still may not be pure gold.
3.Scrape the gold against a piece of unglazed porcelain tile and look at the mark it makes. If the mark appears gray or black, it is not pure gold. If the mark is yellow, it's gold. Keep in mind that it's still possible that the item is gold plated and may not be solid gold.

4.File a small section of the gold in an inconspicuous place using a fine metal file. Pure gold, as a soft metal, will file relatively easily. If filing causes the gold to flake off, of if the metal is very hard to file, it is not pure gold.

5.Conduct an acid test. Put on gloves and safety glasses to begin the acid test, which can be done with a kit or by purchasing hydrochloric acid at a hardware store. Break the tip off a cotton swab and dip it into the acid. Drip a very small amount of acid on the area of the gold that has been filed in an inconspicuous place. If the gold starts to break down, it's not pure gold. Pure gold will not be damaged by the acid.
