There are three differences between "specialized research" and "research": font difference, pronunciation difference and meaning difference.
Differences in glyphs
The difference of glyphs is the most intuitive. The specialty of "specialized research" is concentration, and the bit of "learning" is the bit that is drilled.
Pronunciation difference
"Specialized research" is pronounced as "specialized research" and "research" is pronounced as "specialized research", one with "H" and the other without.
Differences in meaning

The meaning of "specialized research" refers to the study of a certain subject. Emphasize specialization, centralization and uniqueness. And "study" refers to in-depth and meticulous research. Emphasis on depth and detail is not necessarily unique.

Characters can be divided into ideographic characters, phonography characters and logotype characters according to their phonetics and glyphs. Phonetics and morphemes can be divided into phonemes, syllables and morphemes. Hieroglyphs are hieroglyphics of early primitive human characters, such as: the sacred script of ancient Egypt, cuneiform script of two rivers valley, ancient Indian script, Mayan script of America and early Chinese characters.
