16735 仿真结果表明，该文所提网络资源分配算法可以有效地保证用户的个性化QoS需求，提升异构网络综合性能。 The simulation results show that the proposed algorithm can meet thepersonalized QoS requirements of users and significantly improve the comprehensive performance ofheterogeneous networks.
16736 基于杂波谱稀疏恢复的空时自适应处理(STAP)方法可以显著降低对杂波样本数的要求，十分适合缺少样本情况下的机载雷达杂波抑制。 Sparse recovery Space-Time Adaptive Processing (STAP) can reduce the requirements of cluttersamples, and suppress effectively clutter using limited training samples for airborne radar.
16737 然而，现有稀疏恢复STAP方法利用离散化空时导向矢量字典进行重构，在非正侧视阵情况下，由于杂波脊不在字典网格点上，字典失配问题严重影响杂波抑制性能。 The whole space-time plane is discretized into small grid points uniformly in presently available sparse recovery STAP methods,however, the clutter ridge is not located exactly on the pre-discretized grid points in non-sidelooking STAPradar. The dictionary mismatch effect degrades the performance of STAP significantly.
16738 针对上述问题，该文提出了一种基于原子范数的无网格稀疏恢复空时自适应处理方法(ANM-STAP)，利用低秩矩阵恢复理论实现连续空时平面的稀疏恢复，克服了稀疏恢复中的字典失配问题，获得了非正侧视阵情况下的高分辨率杂波空时谱，有效提高了STAP杂波抑制性能。 In this paper, a gridlesssparse recovery STAP method is proposed based on Atomic Norm Minimization (ANM-STAP), which utilizes thelow-rank property of the clutter covariance matrix. In the proposed method, the clutter spectrum is precisely estimated in continuous space-time plane without dictionary mismatch.
16739 Monte Carlo实验证明，该文方法STAP处理性能在非正侧视阵情况下优于已有字典离散化处理的稀疏恢复STAP方法。 Numerical results show that the proposed methodprovides an improved performance to the sparse recovery STAP methods with discretized dictionaries.
16740 高频组件是空间行波管的主要部件，是管内传播高频电磁波的重要传输部件，其中陶瓷封接部位一般采用银焊料进行焊接，它一般存放于真空柜中。 The microwave window is the main component of the space traveling wave tube and an important transmission component for transmitting high-frequency electromagnetic waves in the tube.
16741 存放一段时间后，组件表面出现了发黑现象。 The microwavewindow is generally welded with silver solder, and stored in a vacuum cabinet.
16742 分析表明真空柜中放置的橡胶制品导致了高频组件银焊料焊接部位发生硫化，导致贮存失效。 After storage for some time, themicrowave window surface becomes black. The analysis shows that the rubber products placed in the vacuum cabinet cause vulcanization of the silver soldered joints of the high-frequency components, leading to storage failure.
16743 结合实验结果和理论分析，在大气状态下，橡胶套中的硫是比较稳定的。 Combining experimental results and theoretical analysis, the sulfur in the rubber is relatively stableunder atmospheric conditions.
16744 然而在真空状态下，硫是比较容易从橡胶套中升华进入真空柜中的，从而会在真空柜中弥漫大量硫蒸气，这些硫蒸气与银焊料发生化学反应形成Ag2S，因此含硫的橡胶套不宜放入真空柜。 However, in a vacuum state, sulfur is relatively easy to sublimate from the rubber into the vacuum cabinet, which will diffuse a large amount of sulfur vapor in the vacuum cabinet. These sulfur vapors react with the silver solder to form Ag2S, so the sulfur-containing rubber should not be placed in a vacuum cabinet.
