shell structure

[′shel ‚strək·chər]
(nuclear physics)
Structure of the nucleus in which nucleons of each kind occupy quantum states which are in groups of approximately the same energy, called shells, the number of nucleons in each shell being limited by the Pauli exclusion principle.

Ideal for use in power converters, hybrid electric vehicles, battery management systems, heavy equipment electrification, starter generators as well as 2- and 3-phase motors, these 2- and 3-pole connectors feature a plastic shell structure and small footprint.
In these, an existing structure--such as a warehouse--is used as a shell structure and a simple factory built inside.
Bearing those perspectives in mind, we pay special attention to melamine-dicyandiamide-formaldehyde-phosphoric acid (denoted as MDFP), an inexpensive and efficient macromolecule flame retardant widely used in wood cellulose matrix material [20-22], Thus, in this research, we adopt MDFP as the shell material to synthesize ZHS@MDFP, a novel composite flame retardant with nanoscale inorganic core-organic shell structure, via masterbatch method, hoping to improve the compatibility between ZFIS and flexible PVC matrix by surface-capping ZHS with MDFP rather than conventional small molecule organics or polymers.

In addition, it uses two types of resin in a core shell structure, so that a soft resin is used in the shell to encourage bonding between particles.
According to numerous studies, shell structure is an accessible and reliable archive of bivalve growth dynamics (for a review see Richardson (2001)).
This might have been covered by a utilitarian roof; instead, something in the best Victorian railway tradition has been created: a soaring diagrid shell structure of complex geometry designed by Arup which is high enough to enclose a long and pleasingly sinuous first-floor balcony to contain more of the retail facilities a modern station needs.
The major axis span and rise of the shell structure are 38 m and 6 m, respectively.

The design of the Capital Gate tower meant that the first component to be constructed was the glass shell structure, comprising hundreds of unique panels of glass.
The application of these machines ranges from shell structure, wall structure, reinforced concrete road, retaining wall, protection slope, grating trench cover, floor grating, grill floor, metal floor, ribbed and pressed metal mesh, forge-welded grating, concrete reinforcement, construction fence, concrete forming system, reinforcement fabric, concrete meshes, prefabricated steel reinforcing material and fabricated stainless steel wirework, all of these construction works are able to be finished by GSA series BRC wire mesh welding machine.
