研磨粒料.第4部分:試驗篩分機規范The investigation on natural anticariogenics has become one of the highlights now. chinese scholars have made great progresses in this aspect. they established oral ecosystem model to evaluate natural anticariogenics, studied the pharmacodynamics of effective constituents and their anticarious mechanisms, and standardized screening experimental methods. the review is to overview the progresses of natural anticariogenics
天然藥物防齲是目前研究的熱點，我國學者在天然藥物防齲研究方面取得很大的進展，建立了藥物防齲效果評價的口腔生態模型，對防齲天然藥物進行有效成分藥效學研究和防齲機制等系統研究，規范了藥物防齲篩選實驗方法。Through the test of the separating sieve ' s and beams vibration acceleration, the dynamic bending moment, torque and shearing force as well as the analyze of each parameter by dividing rotation speed range from 300 r / min to 600 r / min of the main shaft, the change regularity of the vibration of the separating sieve, the vibration and the dynamic load on dangerous cross section with the change of rotation speed of the main shaft is obtained. research shows that there exits apparent relevance between the vibration as well as the dynamic load of the main beam and the vibration of the separating sieve. the vibration of the separating sieve mainly affects the composition of low frequency of the vibratio n of the main beam, appropriately amending the vibration acceleration of the separating sieve, the loading and vibration of the mam beam can be directly improved
通過分檔測試主軸轉速在300 600r min范圍內分離篩與梁的振動加速度、梁所承受的動態彎矩、扭矩和剪力以及各參量的時頻域分析，得到了主軸轉速與分離篩振動、主梁的振動及其危險截面的動態載荷間的變化規律，研究表明梁的振動和其所承受的動載與分離篩的振動之間具有明顯的相關性，分離篩的振動主要影響梁振動的低頻成分，適度改善分離篩的振動加速度，可直接改善梁的負載和振動特性。
