酸式硫酸鹽 的英文怎麼說
中文拼音 [suānshìliúsuānyán]
酸式硫酸鹽
英文
acid sulfate-
Chemical industry information not merely embodyed the ordinary chemistry information substance, chemistry manufacture technological process and representative installation introduction are still have, in case contacing legal institutions sulphuric acid ? nitric acid industry system law ( ammonia oxidate law ), synthetic ammonia industry, chlorine and caustic soda are manufacture to electrolysis salt water, along with electrogilding, refine aluminium, iron - smelting and steel - smelting, cement and glass manufacture summarized account, the mineral oil is refined, hence, the chemical industry information education is contrastd against the ordinary chemistry information education, proper such representative means, be living, the means interpreted is in speech oridinarily wholly adoptd in the chemical industry information education, now most of tutors also is adopt the means interpreted in speech, cause that the chemical industry information education is insipid like this, student lack interest to chemical industry information study, but as a result of value the pair foundation, light practice, student may say the become a mere formality to chemical industry information study o since multi - med
化工知識不僅包含了一般化學知識的內容，還帶有化學生產工藝流程及典型設備的介紹，如接觸法制硫酸，硝酸的工業製法（氨氧化法） ，合成氨工業，電解食鹽水製造氯氣和燒堿，以及電鍍、煉鋁、煉鐵和煉鋼，水泥和玻璃的生產簡介，石油的煉制等，因此，化工知識教學與一般化學知識教學相比，應有其典型的方法。在過去，化工知識的教學一般都採用口頭講解的方法，現在大多數教師也是採用口頭講解的方法，這樣使得化工知識的教學乏味，學生對化工知識的學習缺乏興趣，又因重視雙基，輕實踐，學生對化工知識的學習可以說流於形式。由於多媒體的輔助教學的高效性、形象直觀性、新穎性和多樣性、人工模擬等特點，很適合化工知識的教學，應用多媒體教學化工知識可以解決目前存在的諸多問題，如：模型短缺、組織參觀活動困難、教育經費不足、學生不易觀察等。For the background of our ten - five main scientific project, based upon the structure and compositions of expert system and their field characteristics and software development mode, the ideas and methods of expert system of concrete sulfate resistance project are discussed in this article, and a prototype of system integration is given
本文結合國家「十五「重點攻關項目（混凝土安全性專家系統）中的子系統?抗硫酸鹽侵蝕專家系統，根據專家系統的組成結構和領域特點，結合知識結構的一種新的組織和表示模式，研究了專家系統開發的實現技術，並對其進行了最後的集成。Producer of barium and strontium salts in china. products include nitrates, sulfates, hydroxides, and chlorides, as well as some inorganic coproducts
-主要生產重鉻酸鈉酸酐鹽基性硫酸鉻等鉻鹽產品，包括公司簡介，產品介紹和聯系方式等。For concrete structure in the practical engineering, the non - mechanics damages, such as alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw, and so on, are unavoidable due to the exist of erosive media. the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly, and shortens the service life of the concrete to a large extent. permeability of concrete is the most important factor for these non - mechanics damages, so the permeability test of concrete is the normal and required item to study the durability of concrete
實際工程中的混凝土結構，因侵蝕性介質的存在而使非力學破壞行為無處不在，這些非力學破壞行為包括堿集料反應、硫酸鹽侵蝕、碳化、鋼筋銹蝕、凍融等，單一的破壞形式或多形式的復合破壞作用對混凝土結構性能及耐久性能均有著較為嚴重的影響，在很大程度上縮短了建築物的服役年限，而這些非力學破壞在很大程度上取決于其滲透性，所以測試混凝土滲透性能是研究判斷混凝土耐久性的常規必測項目。Producer of a range of nitrate salts, as well as copper - based hydrogenation catalysts used in the production of furfuryl alcohol
-生產硫酸氟化鹽系列化工產品。包括公司簡介產品指標聯系方式。Determination of cadimium in cucumber with four types of sample preparation methods, i. e. digestion using nitric acid and perchloric acid, microwave digestion using nitric acid, digestion using sulfuric acid and hydrogen peroxide and extraction using hydrochloric acid were compared
