為達到進階通用無線接取之預期中的頻譜效益及傳輸能力,已有相當多的提案針對多重天線系統中的需求考量進行討論並做出結論。With experiments and theoretical analyzing, we find when the heat discharge is smaller than the entrainment limited, what influences the ability of heat - transmitting of work quality is the quantity of injection and dry limit fluid inventory, the optimum quantity of injection of the three working fluid is 8 ~ 14g ; and the delivering factor that transmission coefficient is determined by capillary limit, not the heat transmission ability of the thermal syphon. therefore, among the three working fluid, acetone is the best. low wind - speed has the obvious function in heat transmission of the thermal syphon
本文通過實驗研究和理論分析,認為在熱流量小於攜帶極限時,影響工質傳熱能力的是cpu重力熱管的充液量和其乾涸極限,此次所實驗的三種工質,最佳充液量應當在8g ~ 14g ;傳輸因素主要決定普通熱管的毛細極限,而不是重力熱管傳熱能力的決定因素;三種工質中的最佳工質是丙酮;小風速時風速的變化對cpu重力熱管的傳熱有明顯的作用,但在風速大於1m / s以後,風速增加對于cpu重力熱管的傳熱能力的增加效果減緩。A port tyre crane has various parts and complex structure, which is made up plenty of beam - bar and shell elements, manual calculation can not guarantee the precision while finite element method needs onerous structure modeling and a great deal of date input. the finite element analysis and modeling of the port tyre crane are difficult because of complex structure and various loads. in order to fit further more design and exploitation of the same type as well as the upgrade of the production i study a kind of parametric software for structure analysis of the port tyre crane, it can reduce the difficulty of modeling and structure analysis as well as improve efficiency
港口輪胎式起重機部件繁多、結構復雜,由數目眾多的梁桿與板殼組成,其結構設計和力學分析使用傳統的手工計算方法難以保證精度,有限元方法則需要繁重的結構建模和大量的數據輸入,並且要求分析人員具有相當的力學知識和有限元基本理論。港口輪胎起重機結構的復雜性、載荷工況的多變性導致港口輪胎起重機結構有限元建模和分析工作效率低、難度大。針對這種情況本課題研發了一套港口輪胎式起重機結構的有限元參數化分析軟體,以適應同類機型的進一步設計開發和產品升級換代,降低建模和分析的工作難度,提高工作效率。The characteristic and key technologies of the system are as follows : ( 1 ) in realizing the live broadcast of audio and video, the problem of immense multimedia data and low networks bandwidth utilization ratio is solved by using mpeg - 4 as format of audio and video data. audio and video data are collected by video card cv500 which developed by beijing sum tone company ; meanwhile, the contradictory between the delay of networks transmitting and the quality of the image is well solved by setting a " bi - buffer area "
系統實現中解決的關鍵問題和特色主要有以下幾個方面: ( 1 )在視音頻直播功能的實現中,通過使用北京算通公司的cv500視頻採集卡和cv500sdk進行視音頻數據採集,並採用當今最新的圖像和語音編碼壓縮標準mpeg - 4作為視音頻數據的採集格式,既保證了圖像的質量,又大大縮減了視音頻所佔的帶寬,從而解決了多媒體數據量大、網路帶寬利用率低的問題;同時,通過設置環形緩沖區的辦法來調和網路傳輸延時與圖像質量之間的矛盾,取得了較好的效果。On the base of the fujian power system that has the special configuration of " large power generator with small power system " in 2000, constructs power system models of fujian and fujian interconnected with other parts, does a lot of calculation and analysis and simulation, researches the security mechanism and rule of the fujian special power system interconnected with large power system. the above connection can keep security and stability and can make obvious benefits, but when the transmission power reach to excessive quantity the main power grid will increases interconnected flow - in or flow - out exchange power load. the power operation state tended to instability ; the infirmable interconnection make s the damp infirmable
本文以2000年前後具有「大機組小電網」特殊結構的福建電力系統為背景,建立了福建電力系統及其與外部互聯的數學模型,開展大量的模擬計算分析,研究了「大帆組小電網」電力系統與大容量電力系統互聯偏弱的安全穩定性的機理和規律:前述互聯可以安全穩定運行,取得顯著效益,當傳輸功率達到一定量后,主網架增加了送出或吸收互聯交換功率的負載,系統運行狀態向穩定性水平有所下降的方向轉移;聯絡偏弱使阻尼偏弱,聯絡線小幅低頻振蕩和大幅低頻振蕩易被激發,聯絡線一旦重載斷開,系統高周或低調嚴重。Now, the standards of speech compression coding provide a way of transporting speech signals efficiently. in fact, all of them are to reduce the baud rate of data under definite speech quality
相繼出現的語音信號壓縮標準為語音信號的高效傳輸提供了一種有效方法,其實質就是在相當的語音質量指標下,降低數字化語音的數碼率。Future mobile communications have to support the transmission of high rate data and multimedia applications in the radio spectrum, which is already extremely scarce. the basic idea of adaptive coded modulation is to maintain a constant throughput by varying the transmitted power level, symbol transmission rate, constellation size, coding rate or any combination of these parameters. thus, without sacrificing bit - error rate ( ber ), these schemes provide high average spectral efficiency by transmitting at high speeds under favorable channel conditions, and reducing throughput as the channel degrades
自適應編碼調制( adaptivecodedmodulation , acm )的基本思想是在不犧牲系統傳輸性能(比如ber )為代價的前提下,通過單獨改變發送功率、波特率、編碼方案、碼率、調制方式,或者是綜合改變前面所述的各種參數,在有利的通道條件下,獲得較大的吞吐量,當通道質量下將時,相應地降低傳輸速率,最終達到提高平均頻譜效率的目的。分享友人
