In this paper，a kind of Ni- based metal- organic frameworks （Ni- BTC MOFs） was successfully synthesized based on the reaction of Ni（NO3）2 ·6H2O and 1，3，5-benzenetricarboxylic acid （BTC） by one- pot hydrothermal method. The electrochemical properties of Ni- BTC MOFs obtained under the different molar ratio of Ni∶BTC were investigated with cyclic voltammetry and galvanostatic charge-discharge technique. Their structure and surface morphology were characterized with XRD and SEM. The experimental results showed that the discharge time was up to 784 s and the specific capacitance was 1 016. 3 F/g at a current density of 1 A/g，Ni-BTC MOFs synthesized at the Ni to BTC ratio of 1∶1，the reaction temperature of 140 ℃，while the prepared Ni-BTC MOFs was used as the supercapacitor electrode material. The specific capacitance retention rate was 62. 1% after 950 cycles at the current density of 10 A/g.

Carbon-based electrode materials and transition metal oxide materials have their properties as the common electrode materials for supercapacitors. In this paper，graphite was used as the matrix，and metal nickel oxide was coated on the graphite surface with a sol- gel method to form a new capacitor electrode composite. The structure and electrochemical properties of graphite and graphite coated with nickel oxide were characterized by N2 adsorption- desorption analyzer， X- ray diffractometer，electrochemical workstation，and charging and discharging tester. The experimental results showed that the nickel oxide coating could effectively improve the microstructure and electrochemical properties of the graphite matrix. The specific surface area of the material significantly increased， and the pore volume also increased. The nickel oxide coating exhibited obvious characteristics of tantalum capacitance. In the first discharge，the specific capacity of graphite coated with nickel oxide at the current density of 0. 2 A/g was 203. 13 F/g . At the current density of 5 A/g，the discharging specific capacity of graphite coated with nickel oxide was 130. 45 F/g，and graphite was only 90. 02 F/g，and the specific capacity of graphite after nickel oxide coating increased by 45%. There is a synergistic effect between the graphite and nickel oxide coating，and the nickel oxide coating can reduce the impedance of the graphite and improve the cycle performance.

With the rapid development of urban transportation，the convergence and coordination of different transportation tools are always one of the problems that need to be considered and perfected in urban construction. The connection between the traditional rail transit and the conventional bus is not so close，which makes the running cost and the riding cost higher. To solve this problem，with the purpose of minimizing total cost including waiting time cost，riding time cost and running cost，the author set up a mathematical model and used the hybrid genetic algorithm to design urban rail transit connecting bus routes. A specific example was given to illustrate the feasibility of the algorithm in the end；the results showed the convergence rate of the proposed algorithm was better than that of the genetic algorithm.

In digital image processing，the requirements for the input image are high，and if there exists noise and interference in the input image，the feature extraction and the following detection and recognition will be inaccurate. To solve the problem，this paper proposed an image denoising algorithm based on non-subsampled shearlet transform. The algorithm used non-subsampled shearlet transform to decompose the image from multiple dimensions and directions，which could describe the detailed information better，such as outline and curve of the image. Besides，the algorithm utilized the coefficients after the threshold value decomposition，to achieve noise removal. The results showed that the algorithm could keep the detailed information of image after noise removal，which contributed to the image detection and recognition.

At present，the data related to Chinese herbal medicines on the internet is increasing by tens of thousands. It is of great significance to excavate the potential relationship behind these data， establish commodity specifications and price warning mechanism to guide the smooth and orderly running of the market. Taking the information collection of Tiandi website of Chinese herbal medicine as an example，a spider based on Scrapy was designed to extract the information of Chinese herbal medicine name，specifications，origin，price and so on. Firstly，the structure of the target page was analyzed and the XPath path of the target element was extracted with the help of the web page elements reviewing tool of the browser. Then，the web spider project was constructed with the Scrapy framework，and the parsing rules of the target elements and the storage methods of the elements were designed in the corresponding files. Finally，the spider was used to collect the information of the target website for testing. Taking Panax quinquefolium and Panax notoginseng for example，the data collected on-line were compared with the data collected off-line and on the spot. The results show that the designed spider can obtain the information of the target website quickly， efficiently and accurately，it is consistent with the off-line field survey data，also it can provide data support for subsequent study.

Persistent pulmonary hypertension of the new-born（PPHN）is one of the critical diseases in the neonatal period. Its diagnosis，treatment，and care have always been major clinical challenges. In 1992，Kinsella successfully applied inhalation of exogenous nitric oxide on the treatment of PPHN at the first time，which opened up new methods and ideas for the treatment of PPHN. In recent years，the studies have showed that inhaled nitric oxide （ iNO ） therapy combined with non-specific vasodilator drugs could significantly improve the therapeutic effect of PPHN，also it could improve the children′s blood gas parameters and signs of pulmonary hypertension more effectively，more quickly and more securely. However，there were still many problems. In this article，the author summarized PPHN，and reviewed the treatment with nitric oxide and the treatment with iNO combined nonspecific vasodilators on PPHN.
