The system instability is improved by using ac excite and soft compensation in real time 采用交流激勵、軟件實時補償的方法提高了系統(tǒng)的穩(wěn)定性。
Ensure that test data during the development phase is not migrated to production , because the test data can cause system instability 確保開發(fā)期間使用的測試數據沒有遷移到生產環(huán)境中,因為測試數據可能造成系統(tǒng)不穩(wěn)定。
Automatic control function have been realized by means of pid control algorithm of separation integral in the control parts , resolve system instability 在控制部分,采用了分離積分的pid控制算法,實現了對各控制回路的自動控制功能,解決了傳統(tǒng)儀表控制中的不穩(wěn)定問題
A large quantity mass of literatures indicates that it doesn ? t exist an identical conclusion about the influence of capital account liberalization on the financial system . some of them support that capital account liberalization benefits the development of financial system , while someone points that capital account liberalization aggravate the financial system instability 因此,對于包括中國在內的發(fā)展中國家而言,除了保持宏觀經濟的穩(wěn)定發(fā)展,更為重要的是要逐步建立起金融體系的自律機制和有效的金融監(jiān)管體系,才能在資本賬戶開放過程中,保證金融體系的穩(wěn)定發(fā)展。
But the traditional static design method is based on statics and seldom contains guidelines for incorporating the dynamic behavior of the moving belt . large safety factors are employed to accommodate most dynamic stresses in the belt . this can not only increase total cost but also give rise to system instability and higher dynamic stresses that can damage the belt , drums , idlers , bearings and other parts of the conveyor 在高速情況下,帶式輸送機存在的主要問題之一是起制動過程中輸送帶的動張力問題,而傳統(tǒng)的靜態(tài)設計方法將輸送帶視作剛體,并且在靜力學基礎上按靜止或勻速運行狀態(tài)對輸送機系統(tǒng)進行受力分析和參數設計,將動張力以一定系數計入,用加大安全系數方法提高設計可靠性,這不僅會使帶式輸送機的成本提高,還可能引發(fā)起制動過程中較大的輸送帶動應力及運行過程中的不穩(wěn)定性,從而導致輸送帶接頭的失效及滾筒、托輥、軸承乃至其它部件的損壞。
