The obtained QSRRs can not only be used to predict retentions for structurally related compounds, but also be used to elucidate the molecular mechanism of separation for RP-HPLC. In addition, the obtained structural descriptors can be readily used in the studies of quantitative structure-activity relationships .

By means of uniform orthogonal sampling, we represent the shape signature of each model as a statistical distribution of its surface normals weighted by view-dependent depth. The distribution is further processed by spherical harmonics analysis to construct the final representation. By calculating the distance between shape descriptors of individual 3D models, a faithful similarity measurement is achieved.

It is a subdirectory of symbolic links to open file descriptors in use by the program.

它是個包含符號連接的子目錄，這些符號連接指向該程序正使用的打開文件的描述符色综合色狠狠天天综合大色。

Then, the equation of quantitative structure-activity relationship was effectively established with four descriptors like the molecular volume V(subscript m, order zero chi index, sum of the product of solvent-accessible surface area multiplied by partial charge for all positively charged atoms (Jurs-PPSA-3), and molecular surface area.
