In my most humble opinion, single-tray processing for B&W is not worthwhile.
If you have an area large enough area for three or four trays, it's
downright silly. For color, on the other hand, it is the rule.

I agree. I'm curious; why are you (asking the O.P. here) interested in
single-tray processing? Are you working in a closet where you only have
room for one tray? Or is it, as I suspect, because there's some kind of
mystique to the Single-Tray Method, the One True Way to Process Photo
Paper? (At least, that's the impression one gets from Mr. Quinn's many
posts on the subject.) Do you think you'll get better results from it?

Myself, I really don't see the point.

I interested in single-tray because,

1, My room is not large, even thougth it's capable use three trays,
use one tray only is attractive to me;

Well, that seems like the only compelling reason to use just one tray
(although the "tray ladder" suggested here might be a workaround).

2, Using one-tray method means I need to pour solutions back into its
container, this is easy to maintain solution temperature in a water
bath;

But that's what makes this method much more a pain in the ass, in my
view; all that pouring in and out of bottles. And in black & white
processing, who cares about "maintaining solution temperature"? (You
aren't processing color paper, are you?)

Yes, I do B/W. But if solution temperature is not ranged around 68F,
i am not sure how many minutes I should put a paper in the developer.
B/W print is really develop-to-complete? I am afraid if I develop a
paper too much, it will goes darker than it should in normal.


3, A well built, larger, dedicated photographic tray is not cheap.

Really? At least here (the US), trays are probably the cheapest items in
a darkroom. Where are you?

Buy a Jobo AP 8x10 plastic tray in China, you need about 8 dollors,
and 16 dollors for 16'' tray.
