摘要：In this study, the engine suspension system was optimized for making the vibration between engine and car body minimized, and also the optimization was simulated using software Adams. The purpose of this study was to research the vibration isolation of the engine mounting system and implement multi-objective optimization for the intrinsic frequency. In this paper, the optimization was implemented in two ways： （1） the intrinsic frequency was optimized by reasonably allocating it： （2） the intrinsic frequency was optimized using energy decoupling. The optimized intrinsic frequencies were simulated using software Adams and then the simulation results were compared. The simulation results showed that the optimized energy distribution was almost up to 90% and the decoupling degree was greatly improved by comparing the initial data, proving the optimized data played a geater effect on engine vibration isolation and further verifying the feasibility of optimization design method.

摘要：Peasant painting is a kind of painting created by farmers as creative subject,bearing rich *** to the historical development of peasant painting in reality,the types of meaning it carried could be divided into three types in chronological order:political ideological significance,folk life significance,and creative fashion *** three types of meaning gave rise to three types of aesthetic utopia,namely political aesthetic utopia,folk aesthetic utopia and fashion aesthetic *** three types of aesthetic utopia reflected three forms of negation and revolution of daily *** the political aesthetic utopia resisted was the alienation force of material *** folk aesthetic utopia resisted was the desire for material and the binding of political *** fashion aesthetic utopia opposed the relatively narrow *** these three forms of resistance,the public also constructed three identities:the interpreter of their own aesthetic interpretation of political ideology,the interpreter of their own aesthetic interpretation of real life from perspective of local feelings,and the interpreter of their own aesthetic interpretation of real life from perspective of the relationship between themselves and the world.

摘要：近年来,导电碳基质与过渡金属硫化物(TMS)的巧妙结合在超级电容器中取得了一系列的研究进展.然而,在长期的充/放电过程中,这些复合物在异质界面处较弱的兼容性和结合力通常导致TMS的剥离和电极容量的衰减.基于此,本文设计了一种简单且可扩展的原位硫化方法,用于构建稳定的超级电容器电极,其中多孔NiCo/C纳米纤维作为核芯,无定形NiCoS_(x)纳米片作为壳层,形成NiCo/C@NiCoS_(x)(CNCS)分级核壳结构.外部NiCoS_(x)纳米片的质量负载和尺寸在很大程度上取决于内部NiCo/C纳米纤维的碳化温度.优化后的CNCS电极表现出优异的比容量和良好的倍率性能.组装的非对称超级电容器具有突出的能量密度和较高的循环稳定性.这种调节异质界面的原位策略有望用于开发稳定的基于TMS的复合电极.

摘要：The content of this subject research is to conduct optimization for engine mounting system, and through optimization, it can make the vibration between engine and vehicle body achieve a minimum, using Adams software for simulation. It studies the isolation vibration of the engine mounting system and conducts goal optimization for fixed frequency. This paper uses two methods for optimization. One is to use the rational allocation of fixed frequency to optimize the fixed frequency, and the other is to use energy decoupling method to optimize the fixed frequency. It uses Adams software for simulation of the optimized fixed frequency and conducts comparison of simulated results. The simulated results show that the optimized energy distribution situation almost achieves 90%. Compared with original data, decoupling degree also has a very great improvement, illustrating that the optimized data has greater effect for the isolated vibration of engine, in order to further verify the feasibility of optimization design method.

摘要：Study of image enhancement shows that the quality of image heavily relies on human visual system. In this paper, we apply this fact effectively to design a new image enhancement method for medical images that improves the detail regions. First, the eye region of interest （ROI） is segmented; then the Un-sharp Masking （USM） is used to enhance the detail regions. Experiments show that the proposed method can effectively improve the accuracy of medical image enhancement and has a significant effect.

摘要：Reconstructing an HR （high-resolution） image which preserves the image intrinsic structures from its LR （low-resolution） counterpart is highly challenging. This paper proposes a new surface reconstruction algorithm applied to image interpolation. The interpolation surface for the whole image is generated by putting all the quadratic polynomial patches together. In order to eliminate the jaggies of the edge, a new weight fimction containing edge information is incorporated into the patch reconstruction procedure as a constraint. Extensive experimental results demonstrate that our method produces better results across a wide range of scenes in terms of both quantitative evaluation and subjective visual quality.

摘要：Theranostic nanoprobes can potentially integrate imaging and therapeutic capabilities into a single platform,offering a new personalized cancer diagnostic ***,there is a growing concern that their clinical application is not safe,particularly due to metal-containing elements,such as the gadolinium used in magnetic resonance imaging(MRI).We demonstrate for the first time that the photothermal melting of the DNA duplex helix was a reliable and versatile strategy that enables the on-demand degradation of the gadolinium-containing MRI reporter gene from polydopamine(PDA)-based theranostic *** combination of chemotherapy(doxorubicin)and photothermal therapy,which leads to the enhanced anti-tumor *** vivo MRI tracking reveals that renal filtration was able to rapidly clear the free gadolinium-containing MRI reporter from the mice *** results in a decrease in the long-term toxic effect of theranostic MRI *** findings may pave the way to address toxicity issues of the theranostic nanoprobes.

摘要：In this paper, we present a tire defect detection algorithm based on sparse representation. The dictionary learned from reference images can efficiently represent the test image. As the representation coefficients of normal images have a specific distribution, the local feature can be estimate by comparing representation coefficient distribution. Meanwhile, a coding length is used to measure the global features of representation coefficients. The tire defect is located by both these local and global features. Experimental results demonstrate that the proposed method can accurately detect and locate the tire defects.
