Find the law of the influence from the injection pressure to the filling time and the cavity pressure and make certain of the best filling time, injection time and injection pressure. though the analysis of the flowing velocity and pressure spread of the key position element in the injection parts in different gate position, we forecast the injection parts quality and the possibility injection flaw and its position, optimize the gate position. in this paper, though the research of analogue of the runner system of metal - powder injection molding and the process of injection molding, we get the law of how the injection parameter influence the injection process
在相同的注射條件下，通過分析喂料在不同直徑和長度流道中的流動規律，得到了喂料在流道中的速度場、壓力場和溫度場，找到了流道長徑比的合理取值范圍，並得出通過改變流道設計可實現對現有設備資源充分利用的結論；給出了不同注射壓力下，型腔壓力與充模時間關系曲線和喂料熔體平均充填速度與充模時間關系的曲線，得到了注射壓力對充填時間和型腔壓力的影響規律，確定了最佳的充模時間、注射時間和注射壓力；通過分析採用不同位置澆口注射時注射件關鍵位置單元的流動速度和壓力分佈，預測了注射件的成形質量，或可能產生的注射缺陷及位置，優化了澆口設置。 -
Good interface makes it more easy to use and spread. the software has used dynamic programming which is skilled. it can process unlimited short term economic dispatch under the conditions of all the machines " fix time is planed beforehand
本論文在深入研究分析潮汐電站優化調度的基礎上，還採用了面向對象的編程工具vb ，編制了通用的潮汐電站優化調度程序，使程序具有良好的用戶界面，方便用戶的使用和軟體的推廣。 -
As a completely new study method, creative learning treat the questions as the media, create a kind of enviroment and process which are similar to scientific studyjet students collect, analyse, and deal with informations by themselves in order that they can feel and experience the process of creativing knowledge. in this way, they can understand society. learn how to study, cultivate their ability of analysing problems, solving problems and ability of creativeness. as the creative study has the characters of open. experimental processive, which made it can be used widely in all subjects ' teaching and spread thoroughly and quickly. i want to explore how to adopt the creative learning in common school combined with biology teaching through educational experiment. this educational experiment is seclected from two classes ' students in senior two from xi ' an no. 33 middle school. these two classes ' students were regarded as the materials of this experiment. the experiment lasted for three months and adopted natural experienc e. i had two tests before and after the experience. during the class period and free time, i would holden creative learning under the condition of obeying the principal of experiment
作為一種嶄新的學習方式，研究性學習在教學過程中以問題為載體，創設一種類似科學研究的情境和途徑，讓學生通過自己收集，分析和處理信息來實際感覺並體驗知識的產生過程，進而了解社會，學會學習，培養學生分析問題，解決問題的能力和創造能力。由於研究性學習呈現出開放性、自主性、實踐性與過程性等特徵，使得它在各學科教學中得以廣泛運用，並迅速推廣開來。本人通過對國內大量文獻資料的研究，發現研究性學習主要是在經濟、文化發達，教育觀念先進，硬體設施良好的沿海城市及重點中學開展。 -
Wide doppler range. varied code length, varied code rate, which have more difficulties. little acquisition time and high acquisition probability are required during the capturing process of spread spectrum signals
對高動態、高碼率、低信噪比、大多普勒及變化的碼長和碼率的擴頻信號的快捕是本文的難點。 -
Because using ofdm, a frequency - selective fading channel can be transformed into multiple frequency - flat fading sub - channels, in the coding process, spatial diversity ( due to multiple antennas ) is integrated with frequency diversity ( due to delay spread ), therefore, the proposed code can provide higher diversity gain than space - time code alone
該編碼利用正交頻分復用把頻率選擇性衰落通道變換成平衰落通道的特性，同時引入了基於多天線的空間分集和基於時延擴展的頻率分集，比空時編碼具有更高的分集增益。 -
In this paper, firstly large - scale air circulation and weather system evolution are analyzed, and get the scale feature and spread process of the meso - scale convective system by analyzing time - space layout of precipitation and satellite cloud maps. the lower resolution of t213 model and less time - space resolution of data were responsible for the above mentioned misforecast. in this study, the event is simulated by mm5v3. 6 with two - way - interaction and triple nested grid
分析並指出了此次過程中對流降水的演變規律：對流活動引起的高層重力波和邊界層冷涌是對流傳播和觸發大暴雨中心對流活動的主要機制，地面冷空氣的侵入，引起邊界層暖濕空氣的交匯和強烈輻合是對流活動顯著加強的原因。
