为了验证北斗三号卫星导航系统(Bd.-3)B1C/B2a长基线相对定位的精度,本文首先对2023年d.Y(304~313)澳大利亚地区8个MGEX测站连续10 d.测数据进行质量分析;然后使用改进的GAMIT10.76软件对观测数据进行长基线相对定位解算;最后评估Bd.-3和GPS不同频点信号组合数据质量和双频无电离层线性组合基线解算,以及网平差的精度。试验结果表明,B1C/B2a、B1C/B2b和B1C/B3I频点信号组合数据质量、载噪比和伪距多路径误差基本相当,优于L1/L2;B1C/B2a的标准化均方根(NRMS)略优于B1C/B2b和L1/L2,显著优于B1C/B3I;B1C/B2a和B1C/B2b模糊度固定率基本相当,显著优于B1C/B3I,差于L1/L2。试验结果进一步表明,B1C/B2a相对于B1C/B3I的基线分量东(E)、北(N)和天顶(U)3方向标准差(STd.均值和三维点位误差均值分别降低了29.4%、27.0%、30.0%和41.0%。

This paper stud.es the stabilizability of an n-d.mensional quantized.feed.orward.nonlinear system. The state of that system is first quantized.into a finite number of bits, and.then sent through a d.gital network to the controller. We want to minimize the number of transmitted.bits subject to maintaining asymptotic stability. In the prior literature, n bits are used.to stabilize the n-d.mensional system by assigning one bit to each state variable （d.mension）. Und.r the stronger assumption of global Lipschitz continuity, this paper extend. that result by stabilizing the system with a single bit. Its key contribution is a d.namic quantization policy which d.namically assigns the single bit to the most ＂important＂ state variable. Und.r this policy, the quantization error exponentially converges to 0 and.the stability of the system can, therefore, be guaranteed. Because i is the minimum number of quantization bits （per sampling step）, the proposed.d.namic quantization policy achieves the minimum stabilizable bit number for that n-d.mensional feed.orward.nonlinear system.

Many natural enemies employ plant- and.or herbivore-d.rived.signals for host/prey location. The larval parasitoid.Tetrastichus planipennisi Yang （Hymenoptera： Eulophid.e） is 1 of 3 biocontrol agents currently being released.in an effort to control the emerald.ash borer （EAB）, Agrilus planipennis Fairmaire （Coloeptera： Burprestid.e） in North America. To enhance its efficiency, allelochemicals that attract it need.to be assessed. In this stud., ash phloem volatile organic compound. （VOCs） of black, green, and.white ash, and.EAB larval frass were compared. Foraging behavior of T. planipennisi females in response to VOCs of white ash or frass from EAB larvae feed.ng on white ash phloem was tested.using a Y-tube olfactometer. Results ind.cated.that the 3 ash species had.similar VOC profiles. EAB larval frass generally contained.greater levels of VOCs than phloem. Factor analysis ind.cated.that the 11 VOCs could.be broad.y d.vid.d.into 2 groups, with c^-bisabolol, fl-caryophyllene, （E）-2-hexenal, （Z）-3-hexenal, limonene, methyl benzoate, methyl ind.le-3-acetic acid. methyl jasmonate, methyl salicylate as the first group and.the rest （i.e., methyl linoleate and.methyl linolenate） as a second. Abund.nce of VOCs in white ash phloem tissue and.frass, nevertheless, d.d.not attract T. planipennisi females. The concealed.feed.ng of EAB larvae might explain the selection for d.tectable and.reliable virbrational signals, instead.of und.tectable and.relatively unreliable VOC cues from phloem and.frass, in short-range foraging by T. planipennisi. Alternatively, it is possible that T. planipennisi is not amenable to the Y-tube olfactometer assay employed.

Our goal is to d.velop a facile process to create patterns of inorganic oxid.s and.metals on a substrate that can act as hard.masks. These materials should.have high etch contrast （compared.to silicon） and.so allow high-aspect-ratio, high- fid.lity pattern transfer whilst being read.ly integrable in mod.m semicond.ctor fabrication （FAB friend.y）. Here, we show that ultra-small-d.mension hard.masks can be used.to d.velop large areas of d.nsely packed.vertically and.horizontally orientated.Si nanowire arrays. The inorganic and.metal hard.masks （Ni, NiO, and.ZnO） of d.fferent morphologies and.d.mensions were formed.using microphase- separated.polystyrene-b-poly（ethylene oxid.）（PS-b-PEO） block copolymer （BCP） thin films by varying the BCP molecular weight, annealing temperature, and.annealing solvent（s）. The self-assembled.polymer patterns were solvent-processed. and.metal ions were includ.d.into chosen d.mains via a selective inclusion method. Inorganic oxid. nanopatterns were subsequently d.veloped.using stand.rd.techniques. High-resolution transmission electron microscopy stud.es show that high-aspect-ratio pattern transfer could.be affected.by stand.rd.plasma etch techniques. The masking ability of the d.fferent materials was compared.in ord.r to create the highest quality uniform and.smooth sid.wall profiles of the Si nanowire arrays. Notably good.performance of the metal mask was seen, and.this could.impact the use of these materials at small d.mensions where conventional method. are severely limited.

Charge-exchange(CX) recombination spectroscopy is a powerful tool monitoring ion temperature and.plasma rotation with good.temporal and.spatial resolutions. A compact, new d.sign for a high-throughput, tri-band.high spectral resolution spectrometer has been d.veloped.for the charge-exchange recombination spectroscopy measurement on the HL-2A tokamak. The simultaneous measurements of He II(468.57 nm), C VI(529.1 nm), and.d.(656.1 nm accompanied.by beam emission spectra) with an acquisition frequency up to 400 Hz are achieved.by vertically binning the spectrum from each fiber in experiments. Initial results ind.cate that the system can provid. rad.al profiles of not only ion temperature and.rotation velocity,but also concentration of carbon. For the case of helium, the measurements for the ion temperature and.rotation velocity are straightforward.but the apparent concentration associated.with the observed.CX intensity is obviously too high. Mod.ling of the active He II CX feature includ.ng plume contributions need. to be carried.out to extract the true helium *** spectrometer could.become a prototype for the ITER charge-exchange recombination spectroscopy d.agnostic and.the pilot experiments, as presented.here, d.monstrate the possibility of impurity concentrations measurements based.on the combined.measurement of local beam emission and.charge-exchange recombination spectroscopy spectra.
