The author researches from such aspect as scientific management mechanism , reasonable personnel mechanism , good cycle mechanism in education process , antomatic service mechanism in scientific research and market operating mechanism in service sectors in the university 高校內(nèi)部管理機(jī)制運(yùn)行的路徑,可以從科學(xué)的管理機(jī)制、合理的用人機(jī)制、教育過程的良性循環(huán)機(jī)制、科研的主動(dòng)服務(wù)機(jī)制、后勤的市場(chǎng)運(yùn)作機(jī)制等方面加以探尋。
Cf - 5 semi - automatic powder filler main use photoelectric control and synchronous motor spiral material - falling are used in the equipment , antomatic filling , automatic adjusting because of equipping high presicion weight - scaling feedback system , make the precision more correct than former , it is a perfect equipment of large measure powder packing 該機(jī)采用光電控制,步進(jìn)電機(jī)螺旋下料,自動(dòng)充填,自動(dòng)修正由于配備了高精度稱重反饋系統(tǒng),使得計(jì)量精度比以前的更準(zhǔn)確,是大劑量粉劑包裝的理想設(shè)備。
The thesis uses sql server 6 . 0 database , standard sql access interface , and oriented - object program language vc + + to implement our electric network dispatching message management system . the system can operate like this : automaticly check if having data files come ; discriminate file type ; automaticly read data into database ; rapidly give out the precise analysis results , including waveform display , fault component calculating ; select fault phase ; distinguish fault type ; precisely fault allocate ; run all kinds of database administration , like antomatic add - on , automatic deletion , amendment , inquiry by different conditions ; print all kinds of outcome and keep them into database ; share data resource by web technique ; deal with complex faults . the whole system i finished will be powerful technic support for dispatching operation 本文采用標(biāo)準(zhǔn)的sqlserver6 . 0數(shù)據(jù)庫,標(biāo)準(zhǔn)sql訪問接口和面向?qū)ο缶幊坦ぞ遶c + +進(jìn)行編程,實(shí)現(xiàn)了集數(shù)據(jù)庫、分析計(jì)算、圖形化界面、網(wǎng)絡(luò)通訊于一體的電網(wǎng)故障錄波信息管理及故障診斷系統(tǒng),該系統(tǒng)能夠在每次故障后自動(dòng)查詢有無數(shù)據(jù)文件的到來;能夠?qū)魉偷秸{(diào)度端的數(shù)據(jù)文件分析其類型;能夠按comtrade格式自動(dòng)地將大量數(shù)據(jù)信息完整地填入數(shù)據(jù)庫中;能夠進(jìn)行故障選相,故障類型判別和故障精確定位;能夠快速地對(duì)故障做出精確的分析,計(jì)算各次諧波分量,有無功和視在功率,功角,序分量等;能夠?qū)?shù)據(jù)庫進(jìn)行各項(xiàng)管理,如瀏覽,自動(dòng)添加和刪除,修改和按各種不同條件進(jìn)行查詢;能夠?qū)⒂?jì)算結(jié)果,各種表格圖形打印出來和保存進(jìn)數(shù)據(jù)庫中;能夠?qū)⒂?jì)算分析結(jié)果通過web技術(shù)為其他部門提供共享數(shù)據(jù)資源
