Yet the march 1979 burster, with an apparent rotation period of eight seconds, was spinning much more slowly than any radio pulsar then known
但1979年3月那次的爆炸源，看起來卻有八秒的周期，自轉速率要比當時所知的任何波霎還要慢得多。 -
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。 -
Abstract : the article introduces cement slurry rheological characteristics and the method of determining the main parameters for cement slurry rheological characteristics, and analyses the difference between the rotation type and funnel type of viscometers in measuring plastic viscosity and apparent viscosity of cement slurry, and then the limitation of the funnel type of viscometer is described. the difference between rigidity and yield value is pointed out. finally through analysis of cement slurry rheological characteristics, the cement slurry filling mechanism is proposed, and the main factors affecting cement slurry are studied
文摘:介紹塑性流體水泥漿的流變性及確定水泥漿主要流變參數的一般方法；分析旋轉式粘度計與漏斗式粘度計在測定水泥漿塑性粘度、表觀粘度時的區別，說明漏斗式粘度計在使用上的局限性；針對粘聚力（動切力）的測定進行分析，認為粘聚力與動切力為不同的概念.通過對水泥漿流變性分析，提出水泥漿充填機理，並對影響水泥漿擴散的主要因素，即粘度影響水泥漿在節理裂隙中向前擴散的速度，動切力限制水泥漿擴散距離作了說明 -
