其中，在球形區域中有以下一些結果：我們通過打靶法得到了，當角速度是常數時，方程組（ 0 . 1 ）解的存在性和非存在性。而且該解依賴于絕熱常數。For many years, the drying furnace has been adopted with sealed structure and electrical heated, dial instruments are used to control the temperature of the drying furnace and to keep it invariable. parameter setting is inputted by manual method, heating time is completely controlled by operators ’ experiences or their moods, meanwhile, its control function is singular, not only having no automatic heating time and insulating monitoring, having no drying process monitoring, but also having no function of automatic recording and report printing, the workers ’ labor intensity is bigger. thus two abnormal situations are always come forth, one is the insulating performance and intensity of works cannot be guaranteed reliably, it perhaps need to be dried repeatedly, the other is always to extend the drying time in order to ensure the drying quality
多年來乾燥爐一直採用悶罐式結構和電加熱方式，溫度控制採用指針式溫度控制儀表來實現爐溫的恆定，其參數設定由人工輸入，時間控制則完全憑操作者的經驗、情緒來掌握，其控制功能單一，沒有時間控制、絕緣自動監測功能，也沒有乾燥過程監視功能，更沒有多要素記憶、列印存檔功能，工人的勞動強度較大，所以就經常出現兩種異常結果:一是工件的絕緣性能和強度得不到可靠保證，需要反復乾燥;另一種是為保證乾燥質量，往往要延長乾燥時間。However, during my stay in the soho area, especially the hostel, the majority of the women residents were black. through close contact i once shared a room with a black girl, i had the opportunity to learn from them, and found that they are warm - hearted, open - minded, and loving people
后來搬到蘇活區，特別是在招待所內，絕大多數女性房客都是黑人，在與她們深入交往我曾有過一位黑人女室友，有機會向她們學習后，我才發現她們非常熱誠心胸開闊且愛心滿滿，一掃我先前歧視黑色人種的偏頗概念。The demonstration of heat - transfer measuring techniques and prospect of infrared thermal mapping techniques, main parts and performance indexes of a infrared camera, functional blocks and implementation of infrared processing software, experimental facility and measuring system of the wind tunnel has been made. the model emittance was experimentally determined and the three methods correcting directional emittance were compared. those problems of the infinite - slab model thickness and constant wall heat rates hypothesis, the determination of adiabatic wall temperature were discussed in a 1 - d heat conduction analysis
本文對紅外熱圖測熱技術與應用前景、紅外熱像儀主要部件與性能指標、紅外測熱數據處理軟體功能模塊與實現、風洞試驗設備與測量系統等進行了論述，測量了模型表面發射率並對發射率隨極角變化的三種修正方法進行了對比，對一維熱傳導分析中模型壁厚半無限假設、壁面熱流定常假設、絕熱壁溫選取等進行了探討。Organic - inorganic nanocomposite, which are the complex of inorganic nanopraticles with organic compound, is a popular study subject in nanoscale composite. the nanocomposite can not only take advantage of several advantage, but also produce new properties. in this thesis, taking account of the problems in electrorheological fluids such as high leakage current, low yield stress and stability, the pan - batio3 nanocomposite with different structure are prepared by in - situ complex technology and modified sol - gel method
根據目前電流變液中出現的問題（如屈服應力不夠高，漏電流密度不夠低，穩定性不夠好等問題） ，基於聚苯胺有較高的熱穩定性，且密度又小，特別是聚苯胺的介電常數和電導率均可按需調整，此外，鈦酸鋇無機納米粒子作為一種無機鐵電體，在電場作用下具有自發極化的能力，一方面可以為體系提供高的介電常數，另一方面又可保證體系的絕緣性能。For researching behaviours revealed in most products of condensed explosives at cj state which is undissolvable each other, the technjques to prepare an iso - mole adinixture consisted ofwaer ( h, o ) and benzene ( c, h, ) has been developed and measured some useful enersetics parameters by using emulsificaton at normality
為了研究叮態凝聚炸藥不相互溶的絕大部分產物特性，引入乳化技術對典型物質，水刃）苯c札l進行常態等摩爾混合制樣，並測得一些有用的熱力學參數。However the study of metal - oxide hetero - interface is relatively less because the properties of metals and oxides usually differ extremely from each other. contrary to metals, the oxides are usually very brittle, elastically stiffer, insulating and exhibit less thermal expansion and their crystal lattice constants are different from metals. moreover, the preparation of specimen of metal - oxide interface is very difficult, the observation of searching a suitable interface under the electron microscope is also a tedious work
然而，對金屬-氧化物界面結構的研究卻相對少一些，這主要是由於金屬與氧化物之間的性質相差非常大，與金屬相反，氧化物通常很脆、絕熱、熱膨脹系數小，晶格常數也不同於金屬，有的甚至相差很大，而且，制備金屬-氧化物界面比較困難，在電子顯微鏡下全面地觀察一個合適的界面也是一項令人乏味的工作。The resultshowed that the majority of the species in the wan mu ling are of narrow niche, the relationamong the species is very complex and many species share in the resource ; the niche proporrion - al similarity and the niche overlap index reflect the niche characteristics of the evergreen broadleaved woodland in subtropical forest
結果表明：組成萬木林森林群落的種群絕大多數為狹生態位、種群之間關系復雜，對資源具有一定的共享性；種群之間的生態位相似性比例和生態位重疊指數指標值反映了亞熱帶常綠闊葉林的生態特徵。分享友人
