In order to prevent wheat stem lodging and to fertilize precisely, the experiments on the influence of phosphate and potash fertilizers on mechanical properties of wheat stem were performed with Zhengzhou-wheat 9023 as an object. Mechanical properties (such as flexural strength and flexural rigidity) of second base inter-node were measured by six treatments at five growth stages of wheat, which were jointing stage, booting stage, flowering stage, grain-filling stage and maturity stage. Nonmetallic material testing machine was used in the experiments.

Experiments were carried out to verify the static model. Experimental results show that the experimental curve matched well with the simulated curve, and there was certain error between them (maximal static error is 0.035 rad). The error cause was analyzed. Then the experiments were carried out to measure the dynamic performances of the side-sway joint. Experimental results show that the step response time of the joint was about 2 s steady value's tolerance zone ?

On the bases of absorption spectra measurements, it is shown that stabilizer is beneficial to the stability of J-aggregate of sensitizing dye Results of reflection spectra and spectral-exposure experiments demonstrate that spectra absorbance are greatly affected by the adding order of stabilizer and sensitizing dye and only stabilizer added after dye can advantage for J-aggregate of sensitizing dye neatly forming on the surface of silver chloride grain and its absorbance be available ESR experiments show that the addition of stabilizers can decrease the number of dye positive hole and accelerate the decay of it Then desensitization aroused by the recombination of dye positive hole with photoelectron and/or latent image center, was reduced at the presence of the stabilizers

通过溶液光谱实验说明稳定剂有利于染料J聚集体的稳定性;反射光谱实验和光谱曝光实验证明稳定剂与染料的添加次序对乳剂的光吸收有很大的影响,只有稳定剂在染料之后加才有利于染料在AgCl颗粒上排列整齐形成J聚集态及其光吸收;ESR实验结果说明稳定剂的加入可以降低染料正空穴的浓度及其衰减速率,使乳剂中染料正空穴减少,从而抑制了染料正空穴引起的减感作用。因此可以认为稳定剂的超增感作用:一是有利于染料形成J聚集态及乳剂的光吸收;二是降低染料正空穴的浓度,从而抑制染料的减感。同时还提出了染料与稳定剂的增感吸附模型。
