Animal Husbandry and Feed Science 2017年第6期9卷 360-362页

作者： Yang Ting Lei Zhengda zhang yishu Yu Zhiqiang Wang Dayi Sichuan Cereals and Oil Research Institute

[ Objective ] The paper was to study the effects of rapeseed straw on growth and slanghter performance of Sichuan white goose. [ Method ] Totally 400 3-day-old Sichuan white geese were randomly divided into four groups ; geese in control group were fed with the fundamental diet ; geese in group 1, group 2 and group 3 were fed with the fundamental diet containing 5%, 10% and 10% rapeseed straw instead of equal amount of wheat bran, respectively. The body weight and slaughter performance of Sichuan white geese in control group, group 1 and group 2 were determined at 10 weeks of age, while those in group 3 were determined at 14 weeks of age. [ Result] There was no significant difference in gross weight, slaughter weight, eviscerated weight with giblet, head weight, sole weight, wing weight, neck weight, muscular stomach weight and intestine indexes of 10-week-old white geese between group 1 and control group, and between group 2 and con- trol group （ P 〉 0.05 ） ; the live weight slightly decreased. The growth and slaughter performance of 14-week-old Sichuan white geese were significantly higher fllan that of 10-week-old geese （P 〈0.05）, with better meat and flavor, but relatively low average daily gain （P 〈0.05 ） ; there was no significant impact on muscular stomach pH and intestinal pH （P 〉 0.05 ）. [ Conclusion] Substituting partial wheat bran with rapeseed straw can satisfy the diet requirement of Sichuan white geese, but has no significant impact on its growth and slaughter performance （ P 〉 0.05）.

采用水性和油性石墨烯涂层对复合材料防/除冰组件进行测温及防/除冰实验。针对直升机旋翼对结冰的敏感等特点,提出了旋翼防/除冰组件包铁表面涂覆石墨烯涂层改性传热性能的方法,从而提高旋翼防/除冰组件除冰效率。为验证石墨烯涂层对防/除冰组件传热效率具有显著的提高作用,采用搭建的除冰实验平台并对涂覆的旋翼防/除冰组件进行传热实验及除冰实验。结果表明,石墨烯涂层对提高防/除冰组件的传热性能具有显著作用。同时,采用油性石墨烯涂层和水性石墨烯涂层分别进行传热测试,研究表明油性石墨烯涂层升温速率高于水性石墨烯涂层,且油性石墨烯涂层平均传热速率为0.021℃/s,瞬时最大传热速率为0.083℃/s,均高于水性石墨烯涂层,说明油性石墨烯涂层的防/除冰效果优于水性石墨烯。最后,通过改变喷涂工艺控制石墨烯涂层厚度进行研究,研究发现随着石墨烯涂层厚度的增加,涂层的导热系数逐渐减小,该实验结果验证了Balandin等推导的热导率公式中石墨烯热导率与片层厚度之间的反比例关系。

The demand for high-performance X-ray detectors leads to material innovationfor efficient photoelectric conversion and carrier transfer. However, currentX-ray detectors are often susceptible to chemical and irradiation instability,complex fabrication processes, hazardous components, and difficult ***, we investigate a two-dimensional (2D) material with a relativelylow atomic number, Ti_(3)C_(2)T_(x) MXenes, and single crystal silicon for X-ray detectionand single-pixel imaging (SPI). We fabricate a Ti_(3)C_(2)T_(x) MXene/Si X-raydetector demonstrating remarkable optoelectronic performance. This detectorexhibits a sensitivity of 1.2 × 10^(7) μC Gyair^(-1) cm^(-2), a fast response speed with arise time of 31 μs, and an incredibly low detection limit of 2.85 nGyair s^(-1).These superior performances are attributed to the unique charge couplingbehavior under X-ray irradiation via intrinsic polaron formation. The deviceremains stable even after 50 continuous hours of high-dose X-ray *** device fabrication process is compatible with silicon-based semiconductortechnology. Our work suggests new directions for eco-friendly X-ray detectorsand low-radiation imaging system.

基于J-A磁滞模型模拟电流互感器铁芯磁滞特性的关键是模型参数的精准快速识别。针对现有J-A模型参数提取时输入输出均不易测量和提取方法收敛速度慢、精度低等问题,提出了一种基于改进鲸鱼算法的ψ-i J-A磁滞模型的参数提取方法。该模型以磁链和电流为基础,而不是以磁通密度和磁场为基础。采用加入自适应权重值调整和搜索策略的改进鲸鱼算法对参数进行提取。用所提方法和粒子群算法、鲸鱼算法分别识别P型电流互感器和PR型电流互感器的磁滞曲线,对比可得改进鲸鱼算法精度更高、迭代次数更少,验证了所提方法的高效性。

考虑到水印嵌入容量及安全性,探究出水印容量可变的一种数字图像恢复水印算法,利用这种算法对图像特征加以提取,使容量恢复水印得以生成。图像块恢复水印以图像块中随机嵌入密钥低有效位为基础,通过对比恢复水印重构特征与图像块特征,对图像块本身真实性予以判定。变容量恢复水印应该用比特数存储图像块信息,嵌入期间还用于恢复与篡改检测,既有利于减低水印嵌入容量,又有利于算法抵抗恒均值攻击功能的提升,结果表明,数字图像恢复水印算法能够得到质量较高的恢复图像与含水印图像,具有较高拼贴攻击抵抗力。
