This is my last OpenGL for a project to use the "three-dimensional vector space / point" and related functions, they can use a definition of space vector / points, for the vector translation, zooming and rotation, the use of correlation function can also achieve two vector by the fork, get a Vectors absolute length of a vector unit, received a 3:00 decision vector perpendicular to the plane, a space to be the distance between two points, two vector to be the plot points, to be the angle between two vectors, such as operating for the use of user-friendly, each function is detailed Notes, it is particularly important if the calculation vector plot points, fork also took note, we hope to have useful.

The pigments synthesized from 2, 7-diaminoflurenone consistently show better photosensitivity than that containing anthraquinone. A plot of the E1/2 values against the Hammett constant σ was obtained for the pigments which have different substituents in the anilide ring. The plot reveals that neither a strong electron-releasing group, such as methoxy, nor a electron-withdrawing group, such as nitro-group, enhances the sensitivity of the photoreceptor in which these pigments are used as CGL materiel.

Based on the physical meaning of each term in the linear parameter log I (a constant correlating the affinity of solut e t o stationary phase) of stoichiometric displacement model for retention o f solute, the thermodynamic characteristics of log I of solute in revers ed-phase liquid chromatography were investigated theoretically. This poi nt was tested by experimental data with two linear relationships:(1) plot of log I vs 1/T with apolar, polar small solut es and proteins;(2) plot of log I vs log Po/w (partition co effi cient of solute between n-octanol and water) with apolar and polar smal l solutes.

Fluorites formed in uranium mineralization period in the Zoujiashan and Shazhou uranium deposits have ε〓 values from -6.7 to -8.3 and I〓 values from 0.7145 to 0.7204, similar to their host rocks (porphyroblastic lava and sub-granodioritic porphyry) which have ε〓 values from -6.2 to -9.4 and I〓 values from 0.7121～0.7192. On diagram of ε〓- t, the fluorites and host rocks plot in similar area within the evolution field of the basement rocks at Xiangshan. The lead isotopic compositions of pyrites formed in uranium mineralization period plot as a line on diagram of 〓Pb/〓Pb vs.〓Pb/〓Pb. The host rocks plot at the lower value end. Calculation based on the slope of the line and the mineralzation age yields age of 144Ma for the geological body which provided uranium for the mineralization.

Based on the idea of QR decomposition, a geometric blind separation algorithm is proposed for uniform distribution source signals in this paper. It is known that if source signals follow uniform distribution, the scatter plots of source signals and mixtures will show special geometrical property. Firstly, the mixture signals are whiten so that the scatter plot of which is changed into the scatter plot when they are independent, and then the scatter plot of whiten signals is rotated by C ~2 n times Givens transformation.
