I'm a new of studying the OpenFOAM, when i read the 5.3, i can't understand the syntax below:

uniformValue table ((0 0) (10 2)) ????

The guide says inline list of (time value pairs; interpolates values linearly between times)?

What's the meaning of it?

Thank you for your hep.

floquation will become famous soon enough
It is inlined, so if we "outline" it for clarity, it would look like:

Code:
uniformValue    <-- apply the same value to every cell (homogeneous/uniform)
table   <-- this is the value to-be-applied <-- we use a look-up table to apply a different value at different times.
(       <-- start a list
    (0 0)     <-- tuple "at t=0, value=0"
    (10 2)    <-- tuple "at t=10, value=2"
)       <-- end the list
And at times between t=0 and t=10 it linearly interpolates between value=0 and value=2 (assuming your quote is correct; I didn't verify):
