The phrase "allowing particles" is correct and usable in written English.
It can be used in contexts related to science, physics, or chemistry, where the action of permitting or enabling particles to do something is being described.
Example: "The new experiment is designed for allowing particles to interact in a controlled environment."
Alternatives: "permitting particles" or "enabling particles".
He found the walls were porous, allowing particles less than two microns in diameter through but trapping larger bits of phytoplankton or cyanobacteria.
In the temporary absence of the dipole component, the solar wind would approach much closer to Earth, allowing particles that are normally deflected by the field or are trapped in its outer portions to reach the surface.
The strength of this electric field varies over three orders of magnitude along the width of the separator, allowing particles of a much wider size range to be classified and measured simultaneously.
The more energy they can pack into their little fireballs, the farther back in time they can go, closer and closer to the Big Bang and perhaps ultimate truth about nature, allowing particles and laws that once ruled the cosmos, but have since vanished more completely than the dinosaurs, to briefly strut their stuff again.
Using a relaxation Poisson solver and Neumann boundary values interpolated from parent grids, adaptive subgrids can follow the movement of particle subsystems while allowing particles to move from grid to grid.
Compared to other collective rearrangement methods, the modification introduced by this algorithm consists in i) avoiding the particle-to-container shrinking procedure by allowing particles to sequentially settle down and ii) in a stability constraint applied to all the particles in the packing.
Laser-induced incandescence (LII) is a technique allowing particle-size distribution measurement and quantifying in an extremely short time.
The main benefit of this design is that a loose bed of particles accumulates in the blinded pocket of the fitting, allowing particle-particle collision while experiencing a change in the direction of the flow.
In most of the cases, a second treatment is also involved, allowing particle size reduction, intimate mix with carbon additives or the formation of specific structures.
Because the theory allows particles to interact with their own field quanta, mathematical difficulties arose in applying the theory.
This rule does not allow particles with spin 1/2, such as quarks, to occupy the same quantum state.
