Lei has made important contributions in the fields of precision measurement, precision finishing machine design and techniques of hydrostatic and aerostatic support of rubbing surfaces. He successfully manufactured the cutter grinders, internal grinders and boring machines which reached the then world advanced level, and the high speed sliding bearings with centrifugal lubrication as well as light interferometer which measured angles to an accuracy up to 0.002 second. He also investigated phase-modulation variable oil pump which was exported and produced by foreign countries. In the 1960s, he was responsible for developing an angle-dividing device with precision of 1/10 second, which was of the world advanced level. He is also responsible for successfully developing several types of hydrostatic supported screw and nut. In addition, he directed the technical work of manufacturing the nozzle with flexible walls used in the transonic wind tunnel and developed the elastic fluid hydrostatic bearing used in the vibration exciter of vibration testing mount.

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

Expert in civil engineering architectural structure. Born in Nanchang, Jiangxi Province. Graduated from Tsinghua University in 1925. Received MS from MIT,USA in 1928. Vice president and chief engineer, Chinese Research Institute for Building Sciences. Ministry of Building Engineering.

Cai analyzed and summed up various forms of the “One-step momentum distribution method” in general rigid structureanalysis conventionally used and forwarded a more simplified and practical method. Meanwhile, he proposed the I0/I chart rectangular area method for calculating the beams and columns of varying cross-sections to calculate the deflection constants. In the respect of rigid structure using the main beam as the grid formation, he adopted two simplified and practical criteria, the co.umn top momentum action and the grid formation spanning effect, to conduct the calculation concisely following the general rigid structure analysis, achieving results as precise as those of the minimum work method and redundant force method.

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