The phrase "a weak surface" is correct and usable in written English.
It can be used to describe a surface that lacks strength or durability, often in contexts related to materials, construction, or physical properties.
Example: "The engineer noted that the material used for the bridge had a weak surface, which could lead to structural failure over time."
Alternatives: "a fragile surface" or "a brittle surface."
It remains his weakest surface, but with his remarkable touch and ability to shift tactics, it is clearly not a weak surface for him.
The testing results showed that over an area of diameter 40 100 μm, the sensors could detect a weak surface temperature difference of 0.1 0.2 K.
Their magnetization is consistent with a weak surface field of a few hundred to a few thousand nano-Teslas (Collinson 1997; Rochette et al. 2001).
This result means that the healed surface was not a weak surface; rather, healing strengthened the fault so that its strength was equal to or greater than that of the intact host rock.
In such a hybrid device, these sensors remained a stable and repeatable sensitivity for sensing a weak surface temperature difference of 0.1 0.2 K over a local area of 10 100-μm scale.
Monte Carlo simulations based upon nucleation and growth models show that the growth processes controlled by either surface reactions or mass transport of reacting species, including surface diffusion, produce compact deposits with a weak surface disorder.
In the nanosol substrate, the molecular probe of acridine red (AR) exhibited a weak surface-enhanced Raman scattering (SERS) peak at 1506 cm−1 due to its interaction with the rGO of rGO/AgNT.
The case of C10 in Fig. 10d has the same parameters as D4 except a weaker surface friction (i.e., α = 3.5 × 10−5 cyan line in Fig. 5c).
Both simulations produce a relatively weak surface pressure response to solar forcing that does not strongly resemble the Arctic Oscillation.
The spectrum of GNR-SiO2 shows that GNR-SiO2 has two absorption bands, a weak transverse surface plasmon resonance wavelength (TSPRW) around 520 nm and a strong longitudinal surface plasmon resonance wavelength (LSPRW) around 808 nm.
