熱活化變形 的英文怎麼說
中文拼音 [rèhuóhuàbiànxíng]
熱活化變形
英文
thermally activated deformation-
The first geologic reason for degeneration of the eco - environment in the headwater area of the yellow river is that the increase of the recent geologic function caused desertification and grasslands resource decreased and underside changed, destroied the balance of water - air - heat in the area ; the second is that the water environment changes by the degradation and atrophy of frozen earth cause multilayer and synthesis cause of formation degeneration of the eco - environment ; the third is that the man and rats function accelerated degeneration of the eco - environment in the headwater area of the yellow river
摘要黃河源區生態環境惡化的地質原因之一是現代地質作用增強，形成以荒漠化為主的草地資源退化與下墊面改變，地區水氣熱平衡破壞；二是因凍土退化、萎縮，引起水環境變異，導致多層面與綜合成因的生態環境惡化；三是人為及鼠類活動對源區生態環境惡化起著推波助瀾的作用。The hydrothermal activities which were complicated and acted a positive effect in the formation of the zhulazaga gold deposit resulted in hydrothermal alterations of multiepisode, including pyroxeneization, actinolitization, epidotization, ice - feldsparization, silicification, chloritization and carbonatization etc. the research on inclusions in quartz of the ore indicates that the hydrothermal fluid varying greatly in temperature with an average of 286 shows characteristics of high temperature
3 、朱拉扎嘎金礦的形成中熱液活動起到了積極的作用，熱液活動不僅復雜而且具多期性，有透輝石化、陽起石化、綠簾石化、綠泥石化、硅化、冰長石化、碳酸鹽化等。礦石中石英包裹體的研究表明，含礦熱液的溫度變化范圍較寬廣，平均在286 ，顯示中偏高溫特徵。Recently, as an advanced and eco - friendly method of powder preparation, freeze - drying has been developing quickly. the ultrafine ni powder with the average size of 50nm was prepared by freeze - drying form the niso4 and naoh and was studied by means of xrd, ir, fesem, tem, and dsc. the catalysis of nickel powders to nh4clo4 and how the precursor forms and the processes of the amorphous precursor to the final nickel powders are discussed
本論文以分析純niso4 、 naoh為原料，採用冷凍乾燥技術成功的制備了50nm左右的球狀超細鎳粉，通過xrd 、 ir 、 fesem 、 tem 、 dsc等材料現代分析手段對產物進行了分析和表徵，研究了超細鎳粉對高氯酸銨熱分解的催化活性、前驅體的形成以及非晶態金屬鹽到晶態超細鎳粉的轉變過程。The characteristics for this type of heat exchanger are various standards, different shapes, multi - usefulness, completed specifications and same structure but large changing range of sizes for same series. by means of developing the database and drawing libraries, parameterized designing of pipe group units, the cad system for floating - end heat exchanger was developed base on the theory of fixed patterns with flexible sizes
本文針對浮頭式換熱器規格品種繁多、形式各異、使用廣泛、產品設計標準完善、同系列產品圖形結構相同、尺寸變化跨度大的特點，通過數據庫和圖庫的開發、管束組件的參數化設計，運用「死圖活尺寸」的開發理念，研究和開發了浮頭式換熱器輔助設計系統。The thermal state of the piston has been studied under the thermal shock in the first time. the lumped parameter system of the temperature has been established under the triangle rectangle and instantaneous impact. and the simulation results also have been got
