Ceramic grain filters ard made of refined pottery clays added with certain modifiers, and processed of grinding, mixing, shaping and high temperature sintering. they do not contain any substances that harmful to people or environment. they are hard and rough in surface, porous inside the structure, and have the advantages of high mechanical strength, large specific surface area and porosity. when used in water treatment, they behave a activated surface property, a great amount of pollutant entrapment, less water head loss in the filter bed, lower consumption of back - flush water, stable in chemical and gbiologic property, and long service life, ceramic grain filters is a new and efficient filter material to increase the water yield, upgrade the water quality, and save chemicals and energy
陶粒濾料是以精製陶土為主要原料，摻加適量改性劑，經粉碎，混練，成型和高溫煅燒而製成的，不含任何對人體和環境有害的物質.其表面堅硬，粗糙，內部疏鬆，多孔，具有機械強度高，比表面積大，孔隙率大的特性.用於水處理中，具有表面性狀好，截污能力強，過濾水頭損失小，反沖洗耗水量低，化學穩定性和生物學穩定性好，使用壽命長的特點.陶粒濾料是一種能增加水產量，提高出水質量，節省藥劑和能耗的新型高效過濾材料Typical temperature is 800 - 1000 in cvd diamond process, while the high temperature limits its application in optical window and coating such as gaas, zns etc. low temperature can not only make diamond crystal nucleus finer, reduce surface roughness of diamond films and lessen light dispersion, but also eliminate thermal stress
化學氣相沉積金剛石膜過程中，襯底的典型溫度為800 1000 ，這么高的溫度限制了其作為gaas 、 zns等低熔點光學材料窗口和塗層的應用。低溫沉積金剛石膜不僅可以使晶粒細化，降低表面粗糙度，減小光的散射作用，而且可以消除熱應力。But polycrystalline cvd diamond films have rough and non - uniform thickness which can adversely affect their application. furthermore, it is difficulty to machining the cvd diamond thick - film
但是， cvd金剛石膜為多晶材料，表面為雜亂分佈的晶粒的堆積，顯露出明顯的稜角，表面粗糙度大，后續加工比較困難。But affected buy plan economy way, hunan electric power line equipment & materials factory haven ’ t research on iron tower product marketing : research on electric power build environment and policy ; forecast of iron tower product market capacity and market prospect in coming 5 - 10 years or far. thereby is lack of integration think about iron tower product marketing strategy. in this thesis, the author coalition strategy, management, marketing and finance knowledge, on the base of economy, policy, technology macro … environment and produce, technology, manpower, finance ability, corporation culture, marketing manage way micro environment assay, exert swot way, discovery the strengths 、 weaknesses 、 opportunities and threats on hunan electric power line equipment & materials factory iron tower product
在本文中，作者結合所學習的戰略管理、營銷和財務知識，在湖南電力線路器材廠鐵塔產品市場競爭的經濟、政策、技術和行業等外部和生產規模、技術能力、人力資源、財務能力、企業文化、營銷管理模式等內部環境進行粗略分析基礎上，運用swot方法歸納了湖南電力線路器材廠鐵塔產品營銷的政策、歷史悠久、品牌知名度和美譽度高、技術積累、文化等方面的優勢和體制約束、生產規模和生產能力偏小、資金周轉困難、鐵塔加工成本過高、營銷管理模式等方面的劣勢，以及經濟發展和技術革新帶來的機會和體制改革和新的加工工藝帶來的威脅，根據企業的營銷戰略目標，進而提出了相關的鐵塔產品組合、產品包裝和服務策略、價格策略、渠道策略和顧客關系、供應商關系和同行關系等關系營銷策略和具體實施，並制定其營銷實施方案。Then, using the large - scale coarse grained soil test system, the relative density and direct shear characteristics of sand - gravel mixtures in different size distribution were tested. and the soc affecting mechanism derived from non - uniform granular material was discussed. the phenomenon can be observed that, along with the increase of non - uniform degree, the accumulate structure will become more complex, and the sliding resistance among sands will grow accordingly
在此基礎上，利用大型粗顆粒實驗系統，測定不同非均勻系數沙石材料的相對密度和直剪特性，探討了顆粒非均勻程度對自組織臨界性影響的具體物理力學機制：隨著非均勻度的增大，散粒堆積體的顆粒結構空間分佈堆積方式的多樣性增大，顆粒滑動的摩擦耗能增加。The surface morphology and root - mean - square surface roughness of the sio _ 2 films are characterized by scanning electron microscopy ( sem ) and atomic force microscopy ( afm ). the compositional properties of the sio _ 2 films are analyzed by x - ray photoelectron spectroscopy ( xps ). the effects of experiment parameters are discussed
對採用不同實驗參數沉積得到的硅基sio _ 2光波導薄膜材料，用掃描電子顯微鏡（ sem ） 、原子力顯微鏡（ afm ） 、 x射線光電子能譜（ xps ）等方法對材料的表面形貌、粗糙度以及化學組成等特徵進行了研究。In this paper, with complete calculation micro - mechanics method, mass concrete was taken as three - phase composites, which consists of mortar matrix, aggregate and bond between matrix and aggregate. with nonlinear finite element method, the simulation of static and dynamic mechanics performance of the uniaxial compress concrete specimen of dongjiang arch dam and simple supported beam specimen of xiao wan arch dam was studied by means of the software of msc. marc. the number of all kinds of mortar matrix was calculated according to grading of aggregate of three graded concrete and walraven function
本文採用完全細觀計算力學方法，將大體積混凝土在細觀層次上看成是由粗骨料顆粒、硬化水泥砂漿及其二者之間的粘結界面組成的非均質復合材料，採用非線性有限元方法，在對大型商業有限元軟體? msc . marc二次開發的基礎上，對東江拱壩的三級配混凝土軸壓試件、建設中的小灣拱壩三級配混凝土梁試件在靜、動荷載下的力學性能和破壞過程進行了數值模擬。分享友人
