Abstract Marine heatwaves (MHWs) in the South China Sea (SCS) significantly affect both fishery resources and marine ecosystems. The characteristics causal mechanisms of MHWs occurring southern SCS (SSCS) are not yet fully understood. In this study, properties MHWs, their long‐term trends, how these compare to those coastal shelf region northern were explored. It was revealed that coral reef regions SSCS exhibit more frequent but less intense MHWs. Over past four decades, average frequency,...
Abstract In order to manufacture structured surfaces, firstly, the abrasive stone model with staggered particles is established mathematical methods. Secondly, motion of on designed. Finally, surface morphology workpiece simulated. The simulated under different machining parameters compared, and influence obtained. results indicate that microstructured can be lapped by using particles. As amplitude frequency increase, number protrusions increases, area individual decreases.
The traditional view holds that a weakened upwelling has often been observed off the coast of southeast Vietnam during post-El Niño summer. This study investigated strong and concurrent phytoplankton bloom in August 2016 by comparing it with another case 1998. Analyses structure formation mechanisms indicated abnormal was attributable to wind-driven offshore Ekman transport pumping, which were caused accompanying southwesterly anomalies south anomalous cyclone (AC) over western North Pacific...
A good heat dissipating condition will help give full play to the performance and reliability of electronic components devices. To strengthen performance, a novel bionic sink pin fins has been designed. The configuration cooling in this is based on phyllotaxis theory biology. better homogeneity complementarity, which can form reasonable air flow channel improve its efficiency. For testing analyzing effects phyllotactic parameters dissipating, some contrast experiments have conducted using...
The mechanism of material removal under ultrasonic vibration has not been elucidated, which is conducive to its promotion and application in the field machining. Previous research on was mainly conducted through grinding experiments with a single abrasive particle. interference effect particles surface ignored, it obvious that this method shortcomings. In study, tangential assisted (TUVAG) radial (RUVAG) were multiple reveal basic principles formation. Three tools particle arrangements...
