How to mine valuable information from massive multisource heterogeneous data and identify the intention of aerial targets is a major research focus at present. Aiming at the longterm dependence of air target intention recognition, this paper deeply explores the potential attribute features from the spatiotemporal sequence data of the target. First, we build an intelligent dynamic intention recognition framework, including a series of specific processes such as data source, data preprocessing,target space-time, convolutional neural networks-bidirectional gated recurrent unit-atteneion (CBA) model and intention recognition. Then, we analyze and reason the designed CBA model in detail. Finally, through comparison and analysis with other recognition model experiments, our proposed method can effectively improve the accuracy of air target intention recognition,and is of significance to the commanders’ operational command and situation prediction.

环氧树脂虽然具有良好的耐漏电流和抗击穿等电气性能和力学性能,但由于其本身缺乏疏水性,因此在户外绝缘子领域难以大范围应用。为了解决环氧树脂疏水差的问题,采用γ-氨丙基三乙氧基硅烷(APTES)、六氢邻苯二甲酸双缩水甘油酯(CY184)对... 详细信息

环氧树脂虽然具有良好的耐漏电流和抗击穿等电气性能和力学性能,但由于其本身缺乏疏水性,因此在户外绝缘子领域难以大范围应用。为了解决环氧树脂疏水差的问题,采用γ-氨丙基三乙氧基硅烷(APTES)、六氢邻苯二甲酸双缩水甘油酯(CY184)对羟基封端的聚二甲基硅氧烷(HPDMS)进行改性,合成了含有环氧基团的疏水改性剂E-PDMS,并制备了CY184/E-PDMS复合材料。结果表明,接枝了环氧基团的E-PDMS与CY184相容性良好,当E-PDMS质量分数达到10%时,复合材料水接触角能稳定在105°,呈现疏水性;体积电阻率提升至1.36×10^(14)Ω·m,介电常数在1000 Hz下降低至3.55,玻璃化转变温度和拉伸强度分别提升至117℃和59.4 MPa。经过E-PDMS改性后,CY184环氧树脂的疏水性、绝缘性、力学性能、热稳定性等均有明显提升,拓宽了CY184环氧树脂在绝缘子领域的应用。

Based on the observations, the location and the strength of warm(cold) anomaly of SST in surnmer are conrolled mainly by the subtropical highs of atmosphere (typhoon track) on the off shore of the China seas. It may be considered for the physical causes that the factors forming O-SSTA include the dynamic respome of upper layer ocean on tbe strong atmospheric forcing and the shallow sea effects. The former consists of the entrainment, the detrainment, the Ekman pumping and the convergence of surface warm watet; the later the tidal mixing and higher absorptivity. The parameterized expressions and the significance estimations of each factor are shown. The differences of both forming mechanisms and forming time-scales between the warm anomaly and the cold one are also indicated with different forcing systems.
