The phrase "a pair of partial" is not correct and lacks clarity in written English.
It could be used in contexts where you are referring to two incomplete or partial items, but it needs additional context to be meaningful.
Example: "In the experiment, we analyzed a pair of partial results that indicated a trend."
Alternatives: "two incomplete" or "a couple of partials".
The governing equation of plate heat exchanger is a pair of partial differential equations, which is not suitable for model based control.

The Z-closure rule takes a pair of partial splits A|B and C|D, and if A ∩ C, B ∩ C and B ∩ D are all non-empty and A ∩ D is empty, then it replaces the partial splits A|B and C|D with the extended splits A| B ∪ D and A ∪ C | D (c.f. Figure 1).
A comparison is made for two types of core structures of partial dislocations: a pair of partials with Al-terminated/O-terminated extra-half planes and that with Al-/Al-terminated ones.
