Silicon Deposition and Phytolith Morphological Variation in Culm Sheaths of Dendrocalamus brandisii at Different Growth Stages

Bamboo is an efficient silicon accumulator with diverse phytolith morphotypes and composition.The bamboo culm sheath, traditionally considered as a modified leaf, plays a key role in bamboo taxonomy and provides significant mechanical and physiological support for shoot development, but its silicon deposition and phytolith morphological variation r

Analysis of nonlinear vibration characteristics of dual-rotor system under bearing misalignment-rub-coupling fault

In order to reveal the vibration characteristics of fault rotor systems caused by the bearing misalignment, the expression of the rotor deflection displacement under the bearing misalignment Pomade was derived through the coordinate transformation relation.On this basis, the dynamic model of the double disk rotor system with the coupled bearing mis
