The increases in wind speed in this airstream (also part of the cold conveyor belt) resulted from the along-flow pressure gradient force being greater than friction. The second airstream consisted of air parcels that descended west of the cold front and maintained their speed during descent until...
The optimum incidence angle that corresponded with the maximum net lateral-to-normal force ratio was found to be 30掳 for a metasurface exhibiting 75% anomalous conversion efficiency with a phase gradient of 0:71k0.doi:10.1038/s41598-018-28133-2Dylan C. Ullery...
Upper level cold advection and the invasion of surface cold high pressure are main causes of the strong cooling. Downward transport of momentum from high level and strong pressure gradient force are dynamic reasons for the formation of the strong wind. References [1] 张家宝 (1986) 新疆短期天气...
Upon impact, the hydrogel exhibited a strong resis- tance force and effectively absorbed the impact energy. The maximum compressive stress of the aligned CSNF-TA-PVA hydrogel reached 148.2 MPa (Fig. 6b) under high-strain-rate compression (6000 s−1), exceeding the performance of conventional ...
Around that time, a 1,035 mbar (30.6 inHg) high pressure stalled over the Northeastern United States, producing a strong pressure gradient and gale force winds over the East Coast of the United States. 美国东北部上空此时则有1035毫巴(百帕,30.6英寸汞柱)的高气压停留,在美国东岸上空产生强烈的气...
we visualise the generation of a non-uniform composition field in the nanoparticles during lithiation. Stress models based on density functional theory calculations show that the composition gradient is proportional to the applied stress. Based on this coupling, we demonstrate that we can directionally ...
pressure anomaly can be represented by the virtual temperature (Tv; Supplementary Fig.9). In particular, the Laplacian ofTv(\({\nabla }^{2}{T}_{v}\)) has previously been suggested as a key factor for surface convergence in the MLM41. This is physically intuitive, since the gradient ...
At a first approximation, protein osmotic pressure equals zero in the retinal tissue because protein is negligible in the vitreous and retinal extracellular space. Normally, capillary hydrostatic and protein osmotic pressures dominate the force term in the [Starling force] equation. πplasma[plasma onco...
elements. Within this procedure, the force gradient can be calculated as the sum of several local parallel plane interactions, which can be evaluated using the Lifshitz formula. Each local pressure depends on the distance between the sphere and the grating surface at that location, giving as a ...
6) pressure gradient 压强梯度 1. This article assumes that the classic theory of lifting force ommits one crucial factor determining lifting force: pressure gradient. 认为经典升力理论遗漏了一个决定升力的重要因素:流体的压强梯度。 2. The effect of pressure gradient on the prompt explosion energy...
