On the base of the analysis on the advanced technology of hard ferrite in foreign country, the main procedures of preparing hard ferrite pre - sintering material are determined as follows : first, the ferrite oxides coming from the main cold rolling line and strontium carbonate are conveyed to storage tank by gas power and weighed automatically according to the demands of constituent composition. and then they are mixed and grinded by using method of wet treatment. finally the mixtures is transported to the devices of storage by transporting pump
在分析國外先進的永磁鐵氧體生產工藝的基礎上，確定了生產高檔永磁鐵氧體預燒料的主要過程：首先，利用攀鋼冷軋鐵紅為主要原料，將氧化鐵紅及碳酸鍶採用氣力輸送至貯料料倉，經自動稱量裝置，按工藝配方稱量後分別由氧化鐵紅及碳酸鍶發送罐氣力輸送進入預混攪拌筒加水攪拌，然後再送入混磨機濕法混磨；最後，混合物經輸送泵輸送至料漿存儲裝置，經定量進料泵定量輸送至回轉窯進行濕法預燒，預燒料經緩冷至室溫后，再球磨。 -
It is showed that numerical calculation could give the same position of separation line with the cold gas simulation. however, numerical simulation result is of a little deferent from cold gas simulation in some details, such as recirculation velocity and turbulent intensity. the main problem of numerical simulation is that the turbulent model is not perfect, and the computational grid is not precise enough
利用實驗結果對數值模擬的準確性作了檢驗和評價，結果表明數值模擬能給出與實驗結果一致的分離線位置，但在某些流動細節上還有差別，如迴流速度大小和湍流度等，數值模擬中存在的主要問題是湍流模型不夠完善和網格生成不夠精細。 -

由廈門金旅行車有限公司最新推出的「騰」系列客車，一上市就獲得客戶的青睞，日前浙江慈溪市公路運輸總公司一次性就訂購了近臺騰系列豪華客車。 -
As a link between upstream and downstream in petrol - chemical industry in china, pipeline transmission play an important role. along with the reform in china petrol and chemical line, the oil - gas pipe market was divided into three parts. there are three main competitors : petrol - china pipeline company ; transport & storage company and west - south transport, their competition are very fiery each other
1998年中國三大石油公司的重組改制打破了中國油氣管道運輸業由一家企業? ?原中國石油天然氣總公司廊坊管道局一統天下的局面，在原管道局的基礎上，一分為二，分別組建了中國石油管道公司和中國石化管道儲運公司。 -
This thesis disusses the current states and the matter of the transformer condition monitoring and diagnosis fault. afer analying that dga can only reflect the fault type but ca n ' t confirm the fault location, part - discharging signal can realize fault location in theory but ca n ' t be carried out easily for the inconstant influence of circumstance, we present a method that conbinates the oli - gas and electric quanlities to monitor the transformer. using on - line monitoring of oli - gas conform the fault type. using on - line electric quanlities confirm the fault location. with this method, a fault diagnosis system and corresponding diangnosis flow are proprosed. the main work of this thesis consists of the following parts : 1
本文主要研究了電力變壓器狀態監測與故障診斷的現狀以及存在的問題，針對目前dga （油中溶解氣體色譜分析法）只能定性分析變壓器的故障，不能進行故障定位，而局部放電雖然能夠進行故障定位，但由於現場的干擾復雜多變，難以提取有效的局部放電信號，從而提出了結合油氣量和電氣量兩個方面對變壓器進行狀態監測。通過油氣量在線監測，判斷其故障類型和性質；通過電氣量在線監測，對變壓器的關鍵部件? ?繞組實現故障定位。 -
Within the country and abroad, the main means of on - line monitoring transformer is : dissolved gas analysis in oil partial discharge and windings deform on - line monitoring
目前，國內外監測變壓器的手段主要有：油中溶解氣體在線監測、變壓器局部放電在線監測、變壓器繞組變形在線監測。
