  1. 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
  2. Are uncertain and should be regarded as random variables, therefore the reinforced concrete frame is stochastic structure inherently, and then its motive equations converted to combined random differential equations for the uncertain parameters and external random excitation. these equations were solved by order - orthogonal expansion method with pseudo - excitation method, and then the statistic stochastic responses of random structure were obtained. at last, based on the stochastic cumulative damage model with double parameters developed by park, formulas were formulated for calculating structural earthquake damage probability using the structural reliability theory ( mainly jc algorithm ) in extensive random space

    首先對受地震激勵的剪切型鋼筋混凝土結構進行建模，用隨機等效線性化方法將二階非線性微分方程組化成一階線性微分方程組（或稱之為狀態方程） ；再考慮材料等參數的隨機性，則狀態方程成為復合隨機微分方程組，將擴階系統方法和虛擬激勵方法推廣並應用於這個復合隨機微分方程組，求出結構的隨機響應量的統計參數；最後採用隨機累積損傷破壞準則，在廣義隨機空間內，用jc演算法求解失效概率，進而求出結構的抗震可靠度。
  3. According to the main cause of the heat loss in the course of conveying and applying steam, the steam - piping system of southwest jiaotong university has been rebuilt by designing and installing pipe rightly, optimizing the heat - insulating material and its thickness, reasonably selecting drainage valve and reasonably reclaiming condensate, the steam exploitation efficiency has been improved

    根據蒸汽輸送、使用過程中熱損失的主要原因，利用管道的正確設計與安裝、優化的保溫材料和厚度、疏水閥的合理選擇及冷凝水的合理回收改造西南交大熱力管網，提高了蒸汽的利用效率。
  4. Core losses are caused by an alternating magnetic field in the core material, thie losses are a function of the operating frequency and the total magnetic flux swing, the total core losses are made up of three main components, hysteresis eddy current and residuallosses, these losses vary considerably from one magnetic material to a - nother, applications such as higher power and hither frequency switching regulators and rf designs require careful core selection to yield the highestinductor perfor - mance by keeping the core losses to a minimum

    鐵損是由於在鐵芯中的變更磁場院所造成，這個損失與操作頻率及總流動的磁通量有關，總鐵損由三個成份組成，磁滯損，過流損及殘留損，這些損失因磁性材料不同而異，在如高功率切換調整器和rf的設計需要小心選擇鐵芯種類以降低鐵損使電感的表現最佳。
  5. For solid - core optical fibers, great endeavor has been made and several kinds of fibers have been obtained. but the following research indicates that traditional solid - core structure has some deadly disadvantages : one is large reflective loss in input ends because of large reflective index of the solid core ; the other is low transmission threshold because of the structure disfigurements of solid - core. so their performances are far from th e applied requirements

    紅外實芯光纖的研究已經深入開展了很久，也開發了一系列樣品，但后來的實驗研究證明，傳統的實芯光纖結構存在著很大的缺點：一是芯層材料的折射率比較大，因而耦合時光纖端面的反射損失比較大；二是實芯結構所存在的結構缺陷大大降低了光纖的能量傳輸閾值，所以其性能還遠不能達到應用的要求。
  6. With the development of city construction, the population is increasing rapidly, skyscrapers and underground buildings are everywhere, flammable materials are used more widely, fires are more likely to happen, thus fire - fighting is very important to national asset and people lives

    隨著城市建設的發展，人口密度增大，高層、地下建築增多，易燃易爆材料增多，城市發生火災的概率就越來越高，所以消防直接關繫到國家財產和人民生命安全，一旦意外發生火災，得不到即時營救，將會造成無法估量的損失。
