The phrase "a typical radius of" is correct and usable in written English.
It can be used when discussing measurements or dimensions in various contexts, such as geometry, physics, or engineering.
Example: "In this experiment, we will use a typical radius of 5 centimeters for the circular samples."
Alternatives: "an average radius of" or "a standard radius of".
Atoms have a typical radius of one to three angstroms.
An Atomic Force Microscope measures the forces between a sharp tip (with a typical radius of 10 100 nm) and a sample surface.
operating in without contact with silicon cantilevers (resonance frequency in the range 204-259 kHz, an integrated Si tip with a typical radius of 10 nm curvature) and with contact with silicon nitride cantilevers (resonance frequency 56 kHz).
Previous reports in AFM-based scratch nanolithography has focused on making different nanodevices and nanosystems, in which a Si or Si3N4 tip with a typical radius of less than 20 nm was used, and the scratch was processed mainly on flexible polymer substrates [1, 11, 18].
The morphologies of the alumina mask, deposited metal layer, and etched silicon were determined by field-emission scanning electron microscopy (FE-SEM, JSM-6701 F, JEOL Ltd., Akishima-shi, Tokyo, Japan) and atomic force microscopy (AFM, Digital Instrument NanoScope IIIa, Tonawanda, NY, USA) using silicon conical tips with a typical radius of curvature of 10 nm.
Here, a (units: cm) denotes a typical radius of the fiber; C m (units: μF/cm) is the membrane capacitance constant; R (units: kΩ·cm) is the electrical resistivity.
A typical radius value of 1.4 Å is often adopted in the literature, which approximates the radius of a water molecule.
By this method, the relationships among porosity, permeability and different pore throat radii are fitted and a typical radius R30 (the pore aperture radius corresponding to 30%% of mercury saturation in a mercury penetration test) selected.
Each spiral is composed of a collection of concentric filaments spaced by a distance b = 17 nm up to a typical radius R = 130 nm similar to the experimental data shown in Figure 2C.
where R is the semi-major axis, R0 is the typical radius of the disk, R1 = R/R0, fd is the dust-to-gas mass ratio, m ¯ = 2.35 m H is the mean particle mass of gas, and Ms = 1M⊙ is the mass of the central star.
(A ) At low viscosity, sperm perform sharp U-turns, see also Video 2. (B ) At high viscosity, the typical radius of the U-turns increases substantially (Video 3 ).
