As investigated, the shape of the fruit was mainly rotundity, and the color of the fruit were red, black, yellow, mauve. Variation coefficient of mineral elements, which revealed wider variation range and rich genetic diversity. Among them, Fe, the content and the variation coefficient of which was the highest(2.12 mg·100g-1 and 26.99%), it has large potential for futher selection. Ripe fruit of 12 wild myrobalan plum seedlings were analyzed using head space-solid phase microextraction and gas chromatography-mass spectrometry. The results showed considerable genetic variations in these aspects: The total content of volatile components, the classes and contents of each compounds classes, the segregation ratio, and content of main components. There were 83 compounds in total belonging to 6 classes detected in 12 wild myrobalan plum seedlings, including esters, alcohols, ketones, aldehydes, heterocycle and Hydrocarbons. Among them, Formic acid, hexyl ester, the content of which was the highest(4.33 μg·g-1),was important character impact odors.

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.

The resolution is improved through optimal combination of bin attributes which are small offset, small bin, wide azimuth, large off-inline distance and high coverage. Then the "feature net" of near surface conditions was created, and the "sudden transition" of near surface variations was found to provide reliable foundation for optimum shooting parameters selection. The effective methods of spectrum analysis were generalized. It is concluded that the target is satisfying sand body interpretation, not pursuing high frequency.

According to research on space between wheel and Cart rut traverse curve of single roadway, the width of strip slab was fixed. When there was horizontal loading on slab, contact state between strip slab and base course was studied, and finite element model was established. Comparing maximum principle stress among different load position on slab, it was found that the critical loading position of cement concrete strips pavement was the middle of longitudinal joint.

In these lasers, a section of Erbium doped fiber without undergoing bump used as saturatable absorber. A self-written grating may be formed by stable standing wave in this absorber. Because selfwritten grating possesses a characteristic of very narrow rejection band and can suppress any other side-band effectively, so the multi-longitudinal mode and mode jumping in other normal fiber ring laser are removed in this one.
