Nanoscale Research Letters

At CFMEs, the DOQ desorption rate constant is substantially higher than for dopamine, so the DOQ leaves the electrode surface more readily and the reduction peak is smaller than the oxidation peak.

Analytical Chemistry

The time constant is substantially larger in the patients with poor neurologic outcome (τ = 14.2 hours in the training set and τ = 20.2 hours in the test set) in comparison to the patients with good neurologic outcome (τ = 6.4 in the training set and τ = 4.5 hours in the test set), indicating that the EEGs of patients with good neurologic outcome show a faster improvement.

Critical Care

However, a number of experiments (cf. the recent review [2]) do show that the specific heat capacity of the base salt mixture, here and in the following we talk about c P, the specific heat capacity at constant pressure, is substantially enhanced by addition of nanoparticles in small amounts (≈ 1 wt.%), i.e., particles whose size distribution is peaked around 10 to 100 nm.

Expert writing Tips

Best practice

When describing experimental conditions or system parameters, use "is substantially constant" to clearly indicate that these factors remain stable and reliable throughout the observation period. This enhances the reproducibility and validity of your results.

Common error

Avoid using "is substantially constant" when there are noticeable fluctuations or deviations. Overstating the stability of a parameter can mislead readers and undermine the accuracy of your analysis. Instead, quantify the degree of variation or use qualifiers like "mostly constant" or "approximately constant" if appropriate.

Linguistic Context

The phrase "is substantially constant" functions as a descriptive predicate, attributing a state of relative stability or invariance to a subject. As Ludwig AI confirms, the expression is usable in written English, particularly in scientific and formal contexts.

Ludwig's WRAP-UP

In summary, the phrase "is substantially constant" is a grammatically correct and usable expression in written English, primarily used to describe a state of relative stability or invariance. As Ludwig AI indicates, its usage is most common in scientific and formal contexts. While alternatives like "remains relatively stable" or "stays largely unchanged" exist, the choice depends on the desired nuance and the formality of the context. When using this phrase, ensure it accurately reflects the degree of stability and avoid overstating the constancy of the parameter being described.
