| 1 | Effect of Metaxenia on Sugars and Organic Acids and Taste Quality of Bagged Fuji Apple Fruits显示文摘In order to provide reference for the selection of appropriate pollination varieties facilitating the improvement of the flavor quality of bagged Fuji apple,the metaxenia effects of 5 pollination varieties on sugars,organic acids and flavor quality of bagged Fuji fruit were studied.The results showed that the 5 pollination varieties had significant metaxenia effects on sugars,organic acids and flavor quality of bagged Fuji fruit.For the sugar components,the fruits pollinated with Golden Delicious and Jinxiuhaitang showed higher glucose contents,and the fruit pollinated with Gala had the highest sucrose content;the fruits pollinated by Gala,Golden Delicious and Ruby exhibited higher malic acids,and the oxalic acid content and the succinic acid content were higher in the fruits pollinated with Jinxiuhaitang and Ruby;and the fruit pollinated with Gala had the highest total sugar content,and the total acid content was higher in the fruits pollinated by Jinxiuhaitang and Ruby.The sugar-acid ratio was higher in the fruits pollinated with Gala and Golden Delicious,and the lowest in the fruit pollinated with Ruby.The sensory evaluation of fruits showed that the fruit pollinated with Ruby tasted sour-sweet,while the fruits pollinated with other 4 pollination varieties were sour and sweet moderately. | Haibo WANG Chuanzeng WANG Lailiang CHENG Yuansheng CHANG Ping HE Linguang LI | 2017 | Agricultural Biotechnology2017，6，4： | 2 |
| 2 | Development of a new high-shear and low-pressure grinding wheel and its grinding characteristics for Inconel718 alloy显示文摘Nickel-based alloy has been widely used due to its outstanding mechanical properties.However, Nickel-based alloy is a typical difficult-to-machine material, which is a great constrain for its application in the manufacturing field. To improve the surface quality of the ground workpiece, a new high-shear and low-pressure grinding wheel, with high ratio of tangential grinding force to normal grinding force, was fabricated for the grinding of selective laser melting(SLM) manufactured Inconel718 alloy. The principle of high-shear and low-pressure grinding process was introduced in detail, which was quite different from the conventional grinding process. The fabrication process of the new grinding wheel was illustrated. A serial of experiments with different processing parameters were carried out to investigate the grinding performance of the developed grinding wheel via analyzing surface roughness and surface morphology of the ground workpiece.The optimal processing parameters of high-shear and low-pressure grinding were obtained. The surface roughness of ground workpiece was reduced to 0.232 μm from the initial value of 0.490 μm under the optimal grinding conditions. It was found that the initial scratches on the ground workpiece were almost completely removed after the observations with the metalloscopy and the fieldemission scanning electron microscopy(FE-SEM). The capability of the newly developed highshear and low-pressure grinding wheel was validated. | Bing LIU Yebing TIAN Jinguo HAN Linguang LI Zhiqiang GU Xintao HU | 2022 | Chinese Journal of Aeronautics2022，35，12： | 0 |
| 3 | Passive mode-locked Er-doped fiber laser pulse generation based on titanium disulfide saturable absorber显示文摘In this study,titanium disulfide(TiS_(2))polyvinyl alcohol(PVA)film-type saturable absorber(SA)is synthesized with a modulation depth of 5.08%and a saturable intensity of 10.62 MW/cm^(2) by liquid-phase exfoliation and spin-coating methods.Since TiS2-based SA has a strong nonlinear saturable absorption property,two types of optical soliton were observed in a mode-locked Er-doped fiber laser.When the pump power was raised to 67.3 mW,a conventional mode-locked pulse train with a repetition rate of 1.716 MHz and a pulse width of 6.57 ps was generated,and the output spectrum centered at 1556.98 nm and 0.466 nm spectral width with obvious Kelly sidebands was obtained.Another type of mode-locked pulse train with the maximum output power of 3.92 mW and pulse energy of 2.28 nJ at the pump power of 517.2 mW was achieved when the polarization controllers were adjusted.Since TiS2-based SA has excellent nonlinear saturable absorption characteristics,broad applications in ultrafast photonic are expected. | Xinxin SHANG Linguang GUO Huanian ZHANG Dengwang LI Qingyang YUE | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，5： | 0 |
