Recently, the China haze becomes more and more serious, but it is very difficult to model and control it. Here, a data-driven model is introduced for the simulation and monitoring of China haze. First, a multi-dimensional evaluation system is built to evaluate the government performance of China haze. Second, a data-driven model is employed to reveal the operation mechanism of China’s haze and is described as a multi input and multi output system. Third, a prototype system is set up to verify the proposed scheme, and the result provides us with a graphical tool to monitor different haze control strategies.

The image security problem is an important area in information security, and image encryption plays a vital role in this day. To protect the image encryption from the attack of quantum algorithm appeared recently, an image encryption method based on quantum Fourier transformation is proposed here. First, the image encryption and Fourier transformation are discussed here, then a encryption function is proposed. Second, a quantum Fourier transformation is introduced to quantum encryption, and the full step of quantum encryption is given as well. Third, the security of the proposed quantum encryption if analyzed, and some propositions are also presented. Lastly, some conclusions are indicated and some possible directions are also listed.

Under uncertain environment, it is very difficult to measure the entropy of quantum information system, because there is no effective method to model the randomness. First, different from the traditional classic uncertainty, a quantum uncertain model is proposed to simulate a quantum information system under uncertain environment, and to simplify the entropy measurement of quantum information system. Second, different from the classic random seed under uncertain environment which is often called as pseudo-random number, here the quantum random is employed to provide us a true random model for the entropy of quantum information system. Third, the complex interaction and entangling activity of uncertain factors of quantum information is modeled as quantum binary instead of classic binary, which can help us to evaluate the entropy of uncertain environment, to analyze the entropy divergence in quantum information system. This work presents a non-classic risk factor measurement for quantum information system and a helpful entropy measurement.

文章通过对22位泰国学生录音样本的听辨判断和部分样本的声学分析,发现了泰国学生汉语语音学习中存在的难点.其中,声母的问题集中在k、h、j、q、x、z、c、zh、ch、sh、r上.韵母偏误主要发生在:o、e、u、-i、-i、ao、ei、ie、ua、uo、ue、iu、ui、ian、uan、un、un、-ng、er上.声调偏误为:阴平不够高;阳平和去声因有较长的预备段而使整个音节增长;上声则总以[211]形式出现.有些偏误虽然未必引起音位混淆,但在很大程度上造成了泰国学生的"洋腔洋调".文章指出,母语及其方言的影响以及使用教学过程中发生的偏误是偏误产生的主要原因.文章最后就如何纠正有关的偏误提出了教学对策.

变压变频电源由于开关的非线性和对电路参数的依赖性,即使采用多种优化方式,也仍然难以提高其动态性能,因此限制了其在更宽负载范围内的运用。在此,依据模糊控制理论,用一个模糊PID开关切换控制,对现有的控制系统进行了改进。仿真结果表明,该方法在没有提高电路复杂度和主开关工作频率的情况下,提高了系统动态性能,拓宽了负载工作范围。
