The problem of no match on time scale between single - time factors and predictor in objective forecast is analyzed , and the necessity and the possibility of using multi - time factors are put forward 摘要分析了在客觀預(yù)報中單時刻因子與預(yù)報量之間存在著時間尺度上的不匹配問題,提出使用多時刻因子的必要性和可能性。
Objective forecasts of large scale meteorological patterns are received from overseas meteorological centres , such as the european centre for medium range weather forecasts and the japan meteorological agency 每日,天氣預(yù)測總部均取得由歐洲中期天氣預(yù)報中心及日本氣象廳等海外氣象中心發(fā)出關(guān)于大尺度氣象形勢的客觀預(yù)報。

Thus the classical self - destructing all - objective experiment to half - objective forecasting experiment in laboratory to achieve the aims such as shortening research and manufacture time , saving developing funds , enhancing reliability and success proportion 它用來在地面檢測飛行器舵機性能,將傳統(tǒng)的自破壞的全實物實驗轉(zhuǎn)化為實驗室條件下的半實物預(yù)測性實驗,以達到縮短研制周期、節(jié)約研制經(jīng)費、提高可靠性和成功率的目的。
The electro - hydraulic load simulator of fin stabilizer is physical half - objective simulative system . its function is to simulate , under laboratory conditions , different kinds of hydrodynamic force exerted on the fin stabilizer so as to detect technical performance index of the driving system of fin stabilizer . thus the classical self - destructing all - objective experiment will be converted to half - objective forecasting experiment in laboratory to achieve the aims such as shortening lead time , saving developing funds , enhancing reliability and success proportion 減搖鰭電液負載仿真臺是一種半實物物理仿真系統(tǒng),其功能是在實驗室的條件下,模擬船舶航行過程中減搖鰭所受的海浪水動力載荷譜,從而檢測減搖鰭驅(qū)動系統(tǒng)的技術(shù)性能指標,將經(jīng)典的自破壞全實物實驗轉(zhuǎn)化為在實驗室條件下的半實物預(yù)測性實驗,以達到縮短研制周期、節(jié)約研制經(jīng)費、提高可靠性和成功率的目的。
The electro - hydraulic load simulator is a typical kind of passive force control system . it ’ s applied to simulate all kinds of loads on rudder under laboratory conditions , thus tradition all - objective experiments will be replaced by half - objective forecasting ones in the lab , so that the performances of rudder can be test conveniently on the ground 電液負載模擬器是典型的被動式力伺服系統(tǒng),主要用于在實驗室條件下復(fù)現(xiàn)舵面所受各種負載,將傳統(tǒng)的實物實驗變?yōu)閷嶒炇覘l件下的預(yù)測實驗,從而達到在地面檢測舵機性能的目的。
