]. Carbon, 2007, 45(5): 1130-1133. [20] 曾 毅, 张武装, 熊 翔. C/C复合材料SiC/ZrB2-MoSi2复合涂层的抗氧化机制[J]. 复合材料学报, 2010, 27(3): 50-55. ZENG Yi, ZHANG Wu-zhuang, XIONG Xiang. Anti- oxidation mechanisms..., and then, the SiC-ZrC-ZrB2 coating was prepared on the surface of C/C composites by pack cementation. The effects of pre-oxidation treatment on the microstructure, anti-oxidation properties and flexural......
, as shown in Fig. 1(d). Further heat treatments were conducted with temperature and holding time in range of 1250-1300 °C and 60-90 min followed by furnace cooling (FC). Anti- oxidation coatings......
considered in anti-inrushing safety factor calculation is drawn by analysis and comparison of various calculation methods. This research provides a reference for the base stability evaluation of similar... of the overburden plus the excavation depth of the shaft, H, is constant (see Figure 3). The expression of normalized critical overburden pressure is the same as the formula of the anti-inrushing safety......
. The strong sharp peak at 599 cm-1 corresponded to the Cr3+-O anti- symmetric stretching vibration [23]. Another strong sharp peak at 1190 cm-1 was assigned to Cr3+-O-H bending vibration [31]. A low......
composites are sintered copper-based oil-containing bearings. The mechanical properties and anti- friction properties of bronze and brass are superior to those of pure copper [3-5]. In the case in which......
. High energy storage performance in (Pb0.858Ba0.1La0.02Y0.008)- (Zr0.65Sn0.3Ti0.05)O3-(Pb0.97La0.02)(Zr0.9Sn0.05Ti0.05)O3 anti- ferroelectric composite ceramics[J]. Ceramics International, 2015, 41(1......
: 1) For the k neighborhood and the k anti- neighborhood in the set X, the adjacency graph G=(V, E) is constructed on the manifold M. If then the vector eij is the euclidean distance between...; (31) where Vε(x) is the ε-neighborhood of the class center x (x is the class center of every fault), and Vε(x) is ε-anti-neighborhood of the class center x. Definition 5......
Mechanics performance test on waterproof structure layer The characteristics of lower-middle elastic modulus, strong anti-permeability and high toughness are required for the waterproof structure... times and 2.00×106 times fatigue loading test. The inner structure of composite material is not damaged by long-term fatigue loading, and it shows that the material has strong anti-fatigue performance......
bacteria; wastewater; zinc pyrithione; zinc 1 Introduction Zinc pyrithione (ZPT) is a broad-spectrum anti- bacterial agent and extensively used as the active antidandruff ingredient in hair care. ZPT......
. The fractional order proportional-integral-derivative (FOPID) controller based on fractional calculus theory is designed to control the steering cylinder’s movement in SBW system. The anti-windup... the bad influence of saturation on the control system, the anti-windup problem is also considered in the FOPID controller design. The key point of the FOPID controller is to tune the adjustable parameters......
