为了研究生长素在水稻根负向光性反应中的作用，用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应，用ELISA法测定根尖的IAA含量，并对种子根弯曲部分进行半薄切片，结果表明：(1)种子根的生长方向既受光的调控也受外施的IAA的调控，根尖向贴有含IAA琼脂块的一侧弯曲生长；(2 )不定根在光照 1.5h后，背光侧的IAA含量明显大于向光侧；(3)种子根尖发生弯曲生长是伸长区的细胞不均等生长所致。

Results present that when the lateral-torsional coupling is considered, the responses in the lateral direction of the coupled system subjected to a initial disturbance and a harmonic excitation in the torsional direction, respectively, can be occurred in different forms, and show great effects. However the responses in torsional direction subjected to lateral disturbance and harmonic excitation are slightish.

对系统进行了非线性响应数值计算和相应的频谱分析，结果显示弯扭耦合后，在扭转方向的扰动和简谐干扰扭矩均会以不同的形式在弯曲方向表现出来，并对系统的弯曲振动产生较大的影响；而弯曲振动对扭转振动的影响则要小得多。

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.

分别从理论和实验上对长周期光栅的折射率特性以及光纤包层半径对长周期光栅特性的影响进行了研究，首次给出了描述光纤包层半径腐蚀和外界折射率改变与长周期光栅共振波长关系的理论表达式，实验与理论和数据模拟的结果很好符合，利用腐蚀光纤包层的方法可以有效地提高LPG的折射率灵敏度；对不同光纤中写入的长周期光栅的弯曲特性进行了实验研究，LPG的透射峰形状及其中心波长随光纤弯曲而发生变化，并且随着弯曲将在短波方向出现新的透射峰，其透射峰的变化规律因所用光敏光纤的不同而不同，这一特性在光纤传感和可调谐滤波器方面有重要的应用前景。
