sieve loading 中文意思是什麼
sieve loading
解釋
篩管裝載-
They are common in many situations, for example as gland cells and epidermal cells, and in xylem and phloem parenchyma, where they are concerned with active loading and unloading of vessels and sieve tubes
許多情況下都有傳遞細胞發揮作用，例如：腺細胞和表皮細胞，還有木質部和韌皮部的薄壁細胞，該處導管和篩管的主動裝填和排空都與傳遞細胞有關。 -
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。 -
The regulation of acid catalytic property of molecular sieve can be realized via surface modification of mesoporous molecular sieve by means of introducing doping metals into skeleton or loading active species onto matrix during synthesizing precursor for mesoporous molecular sieve
在合成介孔分子篩的前驅物中摻雜其他金屬元素而將其引入骨架或將活性組分負載到介孔分子篩的基體上，可以實現對介孔分子篩表面進行表面修飾與改性，以調變分子篩表面的酸催化性能。
