The results show that:(1)the low-noise source-follower circuit can be effectively used to measure the output of PVDF thin film;(2)the piezoelectric coefficient D33 of the PVDF is very sensitive on temperatures;(3)the value of D33 intensively fluctuate in initial loading stage,this means that a pre-load is needed in practice application to keep a constant piezoelectric coefficient D33 of the PVDF;(4)when the compressive load is imposed on the surface of the PVDF along a incline direction,D33 value is obvious changed with changing incline angle,and(5)the frequency bandwidth of the PVDF thin film is very wide,it is more suitable to measure strike or impact loading at various loading conditions.

结果表明：(1)低噪声源跟随电路可有效测量PVDF 薄膜输出；(2)PVDF压电薄膜的压电系数D33对温度很敏感；(3)D33值在加载初始阶段波动很大，所以实际应用中应给PVDF提供一个预压载荷，以确保有一恒定的压电系数D33；(4)当压载荷沿倾斜方向作用在PVDF 表面时，由于有剪切力作用，D33 值会随着倾斜角的变化发生显著改变；(5)PVDF 薄膜具有很宽的频响，更适用于测定不同载荷条件下的侵彻或冲击等动态载荷。

The results show that:(1) The space-charge fields(include dc space-charge fields and ac space-charge fields) have important effect on the beam-wave interaction output power, make the saturated output power lower, saturated position delay;(2) The back-radio excited by the electron beam has little effect on the output power, and can be ignored;(3) The transverse motions of electron beam has some effect of the output power;(4) The means of phase velocity taped and bunch compression can improve the relativistic TWT efficiency, especially bunch compression can greatly improve the efficiency.

五、分析了相对论行波管三维非线性特性，分析结果表明：(1)空间电荷场（包含直流和交流空间电荷场）对注波互作用输出功率影响很大，会造成饱和输出功率减小，饱和位置推后；(2)电子注激发的反向辐射对输出功率影响比较小，基本上可以忽略不计；(3)电子注横向运行对注波互作用的直接影响比较大；(4)通过改变耦合腔内半径来调节慢波结构相速，采用相速跳变和预群聚的方法可以改善相对论行波管的效率，特别是采用预群聚方法，可以尽量提高相对论行波管的效率。

Orchards up and down has witnessed a rich and colorful scene: glowing red apple with a harvest of joy, good mood and hung on the branches; glistening yellow pear children to be outdone, every effort will be proud of the side of his show for everyone; there is lovely little pomegranate, and some cracked a seam, the seed crystal clear dew children out, won a taste, sour-sweet, nourishing my heart, autumn, your beauty, not only in appearance, but also performance in your mind!

果园上下呈现出一派丰富多彩的景象：红彤彤的苹果带着丰收的喜悦，乐呵呵的挂在枝头；黄澄澄的梨儿也不甘示弱，尽力把自己引以为豪的一面展现给大家；还有可爱的小石榴，有的裂开了一条缝，晶莹剔透的籽儿露了出来，摘下一颗尝尝，又酸又甜，滋润着我的心田，秋，你的美不仅在外表，也表现在你的心灵！

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。

a novel miniaturization bow tie rfid tag antenna is proposed based on the triangular sierpinski fractal microstrip.the port characteristics of the proposed antenna are presented by simulation.at the same time,the resonance frequency,the radiation pattern and the efficiency of the sierpinski tag antenna is given.the results of the simulation show that multiple frequency band can be obtained by varying the dimensions of the fractal structure.hence this kind of antenna can be used into the rfid tag antenna very conveniently.

摘 要：基于三角形sierpinski微带分形贴片，提出了一种新型的小尺寸领带结rfid标签天线设计。通过仿真，给出了该分形天线的端口特性，同时给出了该领带结型sierpinski标签天线的谐振频率、方向图以及天线效率。结果表明，采用不同维数的分形结构，可以实现多频段的工作特性，因而该天线可以很方便地应用于rfid电子标签中。

Such examples might be little more than anecdotal, but personality tests show that while firstborns score especially well on the dimension of temperament known as conscientiousness—a sense of general responsibility and follow-through—later-borns score higher on what's known as agreeableness, or the simple ability to get along in the world.

这类例子也许有充其量不过算是名人轶事。但是，性格测试显示出虽然第一胎在性格评分上的得分优异，即：所谓的&尽责&--拥有一种被称之为总体责任和坚持到底的感觉。晚出生的孩子在&随和&或者说与世界相处的能力上得分更高。
