The average contents of phosphrus in alkali feldspars in both comb zone and the first intermediate zone are high, in the range of 0.42-0.22wt%, and gradually increase from 0.21wt% to 0.50wt% as the magma evolves from the third intermediate zone to the core zone. The abnormally low content of phosphrus (＜0.10wt%) in alkali feldspar from the saccharoidal albite zone is considered due to the crystallization of apatites, which gives rise to extreme depletion of phosphrus in residual melt.

The function of 3dB fiber loop mirror in fine wavelength partition is studied. With this theory, a novel narrow linear band, dual-wavelength switchable Er-doped fiber laser is realized.2. An unpumped Er-doped fiber and broadband fiber Bragg grating with high reflectivity is served as an auto-tracking filter, where the space hole-burning effect appears when the laser signal travels and forms standing wave, thus the generation of multi-longitudinal-mode is suppressed. Then the high birefringence fiber loop mirror is introduced to act as comb-liked wavelength filter.

We have developed many kinds of optical methods to measure the insect flight. For example, a beating force measurement method reduces the uncertainty caused by air turbulence; a flow measurement using a frame straddling technique decreases the interval between exposures of the flow;extracting the weak distorted fringes on the dragonfly wing by a correlation algorithm; measuring the camber deformation of a dragonfly wing using projected comb fringe without hypothesizing that the wing is a rigid plate. By measuring the beating force, wing kinematics and flow, simutantously, we can analyze the relationship among many flight parameters.
