The phrase "a very critical parameter" is correct and usable in written English.
It can be used when emphasizing the importance of a specific parameter in a discussion or analysis, particularly in technical or scientific contexts.
Example: "In our experiment, temperature is a very critical parameter that affects the outcome of the results."
Alternatives: "an essential factor" or "a crucial element".
It showed that the thickness of tin solder layer was a very critical parameter for forming high-quality joints.
Time is a very critical parameter for the aviation domain and a delay of even one minute may cause the failure of a critical military mission or the loss of thousands of dollars at civil aviation.
The use of SMA copolymers with a different MA content revealed that the functionality of SMA is a very critical parameter with respect to its compatibilising efficiency in the blends because it influences the miscibility of SMA with PMMA.
In this paper, we present the novel result that, the amplitude of the seed perturbations, is a very critical parameter which decides, whether or not ESF would occur on a given day and that, this threshold level of seed perturbation amplitude required on a given day decreases as the post sunset height of the F layer increases.
Thus, the rate of chilling is a very critical parameter for both shelf-life and safety of products.
We observed precipitation when using higher buffer concentrations up to 333 mM (own unpublished data) and further, such high buffer concentrations contribute relevantly to sample salinity, which was identified to be a very critical parameter for quantification of metabolites at these levels (see below).
Spread is a very critical quality parameter which must be controlled while operation.
Because interference is an inherent and a very critical design parameter for all sorts of wireless communication systems, many of the recently emerging wireless technologies prefer smaller size coverage with reduced transmit power in order to decrease interference.
For most practical applications to MF-based photonic devices, the values of birefringence and transmittance of the materials are two very critical parameters.
7 8 Team decision-making is a very critical aspect of peer review; however, these topics are outside the main parameters of this investigation.
"This is a very critical stage".
