In this paper, chemistry composition, fiber morphology and pulping property in Solidago canadensis were analyzed and determined preliminarily. The results showed that the content of holocellulose was 81.86%, the content of cellulose was 42.63%, the content of lignin was 18.86%, it is feasible for using Solidago canadensis pulping based on it's chemical composition. The ratio of fiber length to width in Solidago canadensis was 36.67, the average length of fiber was 440 μm, and the length of fiber was too short to pulping. The ratio of wall thickness of fiber cell to lumen diameter was 0.34, and it was smaller than that of other woody fiber. In this experiment, four different methods of pulping were as follows: kraft-AQ pulping Ⅰ, kraft-AQ pulping Ⅱ, alkaline pulping, alkaline sulfite adding AQ pulping, but it was difficult for lignin removal in Solidago canadensis.

The strain gradient, the fiber Bragg grating's reflection and the short wavelength loss decide the two stopbands. Because of having no extra loss result from coupler and no high cost result from circuitor, the band pass filter formed by single chirped fiber grating have many good characters such as little insert loss its insert loss is the fiber splice loss, small volume, low cost and excellent property, moreover there is no report about fabricating filter by using this method, thus we will apply national invent paten about the method of fabrication fiber band pass filter using single chirped fiber grating. According to the parameters linearly chirped fiber gratings of Canada BRAGG Photonics Inc.

The experimental results are summarized as follows: the tensile strengh and bending strengh of steel fiber reinforced lightweight aggregate concrete can be improved significantly by the addition of steel fiber; to some extent ,the addition of steel fiber can also increase the compressive strength ,although little , it radically improves the compressive toughness , and the steel fiber reinforced lightweight aggregate concrete will not fall apart with cracks; with the increase of the volume fraction of steel fiber, the elastic modulus is also rising somewhat; Poisson's ratio is influenced little with the addition of the steel fiber and the effect regularity displays unconspicuously.

Analytical formulae are presented for the first time to describe the shift in the resonance wavelength of LPG in response to etching of the fiber cladding or a change in the external refractive index. The accuracy of the formula is confirmed by comparision with numerical simulations and experimental results. We demonstrated that the resonance wavelengths of an etched LPG are more sensitive refractive index than those of an unetched grating. The bending properties of long period fiber grating written in different type fiber are studied experimentally. The transmission peaks and the central wavelength of LPG change with the bending of the fiber. A new peak appears at the shorter wavelength when the fiber is being bent. The changes of the peaks are different for different photosensitive fiber. Those properties have broad application foreground in fiber sensors and tunable filters.

The research which is the important part of the tunable erbium-doped fiber laser is composed of two main parts: 1. the gain part of the tunable erbium-doped fiber laser, which in fact is an erbium-doped fiber amplifier, its output characteristics are discussed both in theory and experiment, and the differences are also discussed between theory and experiment; 2. the saturated absorber part of the tunable erbium-doped fiber laser, also the part to narrow the line width of the fiber laser. The line-width narrowing mechanism in fiber laser induced by unpumped Er-doped fiber is presented from the aspect of coupling wave equation, and the main factor is considered as the standing wave induced by interference. The line-width is narrower when the standing wave is stronger, and the narrowing effect disappears with the disappearance of the standing wave. In the experiment, when adding a Faraday mirror in the laser cavity to remove the standing wave , the narrowing effect disappears. So the theory is proved by the result of the experiment.
