211 There is a graphite stack in it to reflect neutrons and to return them in active zone of reaction.

212 The CAWs , graphite and mineral oil were directly mixed to make the CAW modified carbon paste electrode and the electrocatalysis of the modified electrode to hydroquinone was studied.

213 The laser hardening microscopic structures are mainly very fine martensite and the original pattern of flake graphite basically remain.

214 The diamond,[http://sentencedict.com/graphite.html] SiC and graphite grains with isotopic anomaly of noble gas are separated from original residue of chondrites.

215 As a result, Coating had a good self-lubrication property and the optimum content of graphite was 6%(mass) with which the coating behaved best in wear.

216 Filler generally Baptist oil or graphite coated with asbestos rope.

217 In this paper, the determination of trace plumbic in water by graphite furnace atomic absorption spectrometry using tantalum coated graphite tube is reported.

218 The electrochemical process of 4 - chlorophenol with graphite rods electrodes under different conditions was studied.

219 Owing to its effect of the surface and intrinsic lacuna, carbon nanotubes have perfect reactive ability than other allotrope of graphite.

220 Therefore, compared to other variations, graphite carbon nanotubes have stronger and more flexible response to the active site, having a unique electrical properties.

221 The ammunition security is greatly improved when 1% micro-powder graphite is added into the trinary formulation.

222 Around the primary nodular graphite, the austenite nucleates and grows based on the graphite growth face (0001), and forms a ring like austenite shell finally.

223 Diatomic molecules, N 2 and Cl 2, adsorbed on graphite, are studied using the EHT - cluster method.

224 A comparison between the combinatory graphite electrode and adjustable graphite electrode or traditional steel electrode is made.

225 The present invention relates to one kind of composite porous graphite base phase change energy-storing material and its preparation process.

226 There exists continuous re-distribution of the CV-graphitizing elements in the melt, which is one of the important factors causing deformation of the graphite morphology.

227 Not until the 16th century did the English discover a large deposit of pure graphite(sentencedict.com), then called plumbago (Latin for "lead ore").

228 A new method to determine ferrum in anhydrous hydrazine by graphite furnace atomic absorption spectrometry was set up.

229 The surface induction quenching test on gray iron and spheroidal graphite cast iron indicated that the equipment was easy to operate, and had strong stability, it was provided with practicality value.

230 This graphite boat is provided with three reservoirs and a movable graphite slide.

231 Taking graphite cathode as an example, the transverse discharge characteristics of a self heated cathode are described. It is indicated that the cathode mechanism is hot electron emission.

232 Graphite Electrode is mainly used steelelectric furnace , mineral hot furnace and electric resistance furnace.

233 Determination of trace Mo in ferrosilicon alloy by graphite furnace atomic absorption spectrometry is studied.

234 Reduction experiments have been conducted in a vertical tube furnace using graphite crucible.

235 This type of graphite deposits were formend in the Late Archaean to Early Proterozoic.

236 To compare the two atomic absorption spectrometric methods with flame(FAAS) or with graphite furnace(GFAAS) in determining lead fume and dust in the air of workplaces.

237 The tests show that the solid state products obtained from the organic exhaust gas by plasma jet mainly contain nanosheet graphite and carbon-coated nanometer copper powders.

238 Through the study on both the internal structure and the nucleus shape in low carbon ductile iron, influencing regularity of the nucleus shape on the graphite spheroidization has been discussed.

239 A heat-resistant compacted graphite iron has been produced by using RE composite vermiculate ferroalloy which contains low boil element.

240 Some additives such as graphite, PTFE and CsNO3 can improve obscuring effect of smoke screening in infrared waves.
