  • METHOD FOR DECREASING BASELINE UNDER HIGH TEMPERATURE OF GAS SENSOR

    Systems and methods for preventing reaction between a sealing material (109) such as epoxy and an electrolyte material within a carbon monoxide or other gas electrochemical sensor (100) are provided. In general, the electrochemical sensor (100) comprises a gas diffusion working electrode (110), a counter electrode (116), and optionally, a reference electrode (114). Each electrode (110, 116, 114) is in contact with an aqueous electrolyte. The gas sensor (100) may comprise a tab (117) located proximate to gaps (108) in the housing (102) of the sensor (100), wherein the tab (117) prevents any sealing material (109) that fills the gaps (108) from entering the interior of the housing (102). In some embodiments, the tab (117) may be attached to a counter electrode (116). In some embodiments, the housing (102) may comprise a slot (132) located about the gaps (108), wherein the tab (117) fits into the slot (132) of the housing (102).

  • METHOD AND SYSTEM FOR PARSING MULTI-PROTOCOL MESSAGE BASED ON FILE MODE

    The present invention is applicable to the technical field of data communications, and provides a method for parsing a multi-protocol message based on a file mode, comprising: 1. initializing an algorithm memory resource and a file handle; 2. reading a data stream from a communication port and storing same in a data buffer region in the memory; 3. reading data in the data buffer region, and writing the data into a message file, and meanwhile cleaning an old message file to obtain an updated message file; 4. sharing the message file with all protocol stack parsers; 5. repeating steps 2 to 4; 6. each protocol stack parser using an allocated file handle to read data in the updated message file, and determining whether there is a message with the protocol in the data; and 7. if so, responding to the application of the message after processing the message according to the protocol. The method provided by the present invention solves the problem that, in the existing single processing mode, searching each protocol in turn easily causes the receiving buffer to overflow, thereby leading to data loss.

  • METHOD AND APPARATUS FOR DISPLAYING AN IMAGE, AND ELECTRONIC DEVICE

    A method and apparatus for displaying an image are provided by the present disclosure. A resolution of a display screen on a terminal device which is to display an image to be displayed is determined to obtain a width-to-height pixel ratio of the display screen. A preset zooming image area which is a part of the image to be displayed is determined. If a width-to-height pixel ratio of the preset zooming image area is different from the width-to-height pixel ratio of the display screen, the preset zooming image area is adjusted so that a width-to-height pixel ratio of an adjusted image area is the same with the width-to-height pixel ratio of the display screen. The adjusted image area is a part of the image to be displayed. An equal-ratio zooming operation for the adjusted image area is performed according to the width-to-height pixel ratio of the display screen so as to display an image area obtained by the equal-ratio zooming operation.

  • Preparation and thermophysical properties of Yb-doped Ba2DyAlO5 ceramics

    Liu, Ling   Wang, Yinghua   Ma, Zhuang   Wang, Fuchi   Zhu, Mingming  

    A series of Ba-2(YbxDy1-x)AlO5 (x=0,0.1,0.2,03) ceramics for thermal barrier coatings (TBCs) were prepared by solid state reaction and hot-pressed sintering. Their phase composition, microstructure and the thermo-physical properties were investigated. The results showed that single-phase Ba-2(YbxDY1-x)AlO5 (x=0,0.1,0.2,0.3) with perovskite-like structure were prepared, and performed excellent phase stability under 1400 degrees C. As a function of increasing x, the thermal conductivity of Ba-2(YbxDY1-x)AlO5 decreased firstly and then increased. The minimum value (1.02W. m(-1). K-1) was achieved for the sample with the same composite point x=0.1. The thermal expansion coefficient of the ceramics increased through doping with a maximum value around 11.6 x 10(-6) K-1.

  • The influence of impurities on Ga electrowinning: Vanadium and iron

    Liu, Ling   Wang, Mingyong   Wang, Zhi   Zhang, Yi  

    During the electrolytic extraction of Ga, iron and vanadium are main metal impurities in Ga solution. The influences of Fe(III) and V(V) on current efficiency (QE) of Ga electrowinning were studied. The surface structures of electrodeposited Ga coatings were examined by SEM, EDS and potentiodynarnic polarization. The results indicate that QE is sharply decreased in the presence of V(V). Spherical Ga particles are easily produced in Ga solution with impurities, especially in the presence of V(V) and at higher current density. It is difficult for Ga particles with impurities and newly formed Ga crystals to incorporate into Ga films due to the difference of surface structure and properties between Ga and impurities. As a result, newly formed Ga crystals are easily re-dissolved which leads to the decrease of QE. When both Fe(III) and V(V) exist in Ga solution, QE at lower current density is increased due to the siderophile affinity of Ga. (C) 2014 Elsevier B.V. All rights reserved.
