Lu was mainly engaged in the research on crystal physics and X-ray crystallography. He was one of the primary originators of crystal physics study in China and the chief founder of China’s research contingent for X-ray crystallography. In his early years, he initiated the method for the determination of solid solubility curves in a phase diagram by using crystal lattice constants, which is still used today. In the 1950s, he pubished the paper “Crystal Structure Changes in the τ-Phase of Aluminum-Copper-Nickel Alloys”, winiing great reputation from his colleagues both at home and abroad. Hh also made important contributions to the study of crystal structures and alloy phase diagrams by applying X-ray multi-crystal powder diffraction techniques.

Chen was mainly engaged in the research and education in the theoty of real and complex variable function and differential equations. He was generally acknowledged as the authoritative master in the Chinese mathematics circle, field forerunner in function theory, founder of the studies of many branches of mathematics and a very fruitful educationist. In the 1920s, he independently solved some fundamental mathematical problems such as functions which can be expressed by trigonometric series which are absolutely convergent, and achieved the discrimination theory of nonconditional convergence. He also made enormous contributions in guiding youg teachers and students to carry out scientific research, training qualified personnel and promoting Chinese educational progress.

He became Member of the Chinese Academy of Sciences in 1955.
