Three components of peroxide in the activator amongwhich have the different decomposed temperatures made the Vinyl-ester resinsolidified heat discharge increased that gained a bigger solidified degree. Theactivator-adopted quantity can dramatically affect the casting samples performance:eg. When use 1.0-1.4 portions of activator, the casing sample can reach its maximumTensile strength and Bend strength; when use more activator, the polymeric meshworkcontracted which embrittle the casing sample and reduce the dynamic performance; Inthe Pultrusion processing, when CF composed of about 60vo1%, more demould agentcan bring the better processing but degrade the CFRP, normally use around 1.2 portion.
采用具有不同分解温度的三组分有机过氧化物引发剂,乙烯基酯树脂的固化反应放热量增加,固化程度提高;引发剂用量对浇注体的性能影响很大,在用量为 1.0~1.4 份时,浇注体拉伸强度剂弯曲强度达到最高,过多的引发剂使聚合网络减小,浇注体变脆,力学性能降低;在拉挤成型工艺中,碳纤维的体积含量一般为 60%左右,脱模剂增加使加工性能好转但会使复合材料性能下降,一般用量为 1.2 份。

Oxygen was found to depress their fcc-sctransition temperature Tc from the normal value of 260K,as indicated by theminimum in the temperature-dependent permittivity ε′,and also enlarge the drop in ε′at the transition.The magnitudes of the downward shift in Tc and the drop in ε′were roughly proportional to the O2 occupance at octahedral lattice sites,as estimatedfrom the resonance heights distribution.

Purified GO had a molecular weight between 145, 000 and 162, 300, as determined by Sephadex G-200 filtration and SDS-PAGE of the enzyme as cross-linked with glutaraldehyde. This result showed that the holoenzyme was a tetramer, and no change occurred in molecular weight of the enzyme during the s〓orage. The active form of GO from brassica leaves showed a constant molecular weight during purification, so did that from O. sativa leaves during greening of etiolated seedlings, maybe acting as a stable tetramer.

The laser-cladding layeron the alloy consists of matrix phase of over-saturation solid solution γ and complexhexagonal carbide M_7C_3. Under certain condition, with fast laser scanning speed, the oversaturation solubility of elements increases in γ, and the precipitation of the complexcarbide M_7C_3 decreases, so that the microhardness increases and the wear resistance de-creases. But at slower laser scanning speed, more complex carbide M_7C_3 may precipitate, andthe wear resistance may be improved. Therefore, it is believed that the principal factor in im-provement over wear resistance is the precipitation of carbide M_7C_3, while overmicrohardness is the over-saturation solubility of elements in matrix phase.
表明:(1)激光熔覆合金层是由过饱和的γ基体相和复杂的六方M_7C_3碳化物相所组成(2)在其他参数不变的情况下,随激光扫描速度的提高,γ基体相过饱和度增大,而析出的碳化物含量减少,因而合金层的硬度升高,耐磨性有所下降;而降低激光的扫描速度,碳化物M_7C_3析出增加,有利于提高合金层的耐磨性、因此碳化物M_7C_3析出量是提高耐磨性的主要因素,而增加基体相γ的过饱和度则是硬度提高的主要因素
