This article introduces the design and imaging principles of Advanced Hyperspectral Imager (AHSI) aboard China's GaoFen-5 satellite. The AHSI is a visible nearinfrared (VNIR)/short-wave infrared (SWIR) HSI. It first spaceborne hyperspectral sensor that utilizes both convex-grating spectrophotometry an improved three-concentric-mirror (Offner) configuration. has 330 spectral bands, 60-km swath width, 30-m spatial resolution. Various tests have been designed to evaluate its performance,...
In the design and condition assessment of bridges, extreme vehicle load effects are necessary to be taken into consideration, which may occur during service period bridges. order obtain an accurate extrapolation value based on limited duration, threshold selection is a critical step in peak-over-threshold method. Overly high results little information used excessively low leads large bias parameters estimation generalized Pareto distribution. To investigate this issue, 417 days strain data...
It is very common to use the RS data for work of researchers. Facing a mass data. This paper scripting language python and arcgis software, organize corresponding program make tools, integrated into arcgistoolbox, consequently simplify management. The software are useful promote management speed precision work. there we take Gorges Reservoir Area as an example.
设计合成了3个含不同取代基的二硫杂[3.3]对环番单金属钌炔基化合物 6b ~ 6d 及一个对照化合物 6a . 4个化合物通过 1 H NMR， 13 C 31 P NMR和元素分析进行了表征. 化合物 6c 的结构通过X射线单晶衍射证实，晶体结构显示环芳中上下苯环间存在明显的π-π作用. 同时还利用电化学、红外光谱以及密度泛函理论计算，探究了二硫杂[3.3]对环番配体及其上取代基对金属钌中心电子性质的影响. 电化学研究结果显示，二硫杂[3.3]对环番上取代基（F，CN）可以通过分子内的跨环π-π作用影响钌中心的氧化还原活性，其中氰基的影响最大. 密度泛函理论计算结果显示取代基（F，CN）对配合物的最低未占分子轨道（LUMO）电子云密度分布影响较大，氰基取代的 和氟取代的 ，其LUMO轨道上的电子几乎定域在桥配体的环番上，而 和 ，其LUMO轨道上的电子几乎定域在金属钌及其辅配体上.
Aiming at the current reliability research of distribution network, only N-1 safety criterion is usually considered, and on power supply under different criteria less problem. In this paper, a evaluation method combining depth priority search minimum cut set theory used to solve problem quickly finding in network. Using network which optimizes set, difference between standards home abroad calculated summarized. By comparing guidelines various countries, taking China's DL/T256 United Kingdom...
In this paper, we deal with the event-based tracking control problem for a class of strict-feedback nonlinear systems. An event trigger mechanism is designed in communication channels controller and sensor constructed, which saving computation resource cost without incurring Zeno behavior. Finally, presented method ensures that system output can track reference signal asymptotically all closed-loop signals are bounded. Simulation results shown to validate proposed method.
β-Sialonwhiskers which the molecular structuralformula of β-Sialonis Si 3 Al O N 5 (z = 3) were synthesized from fly ash and graphite under appropriate technological conditions by carbothermal reduction–nitridation process. The effects carbon content, reaction temperature time on synthesis ofβ-Sialonwere analysed XRD, SEM techniques. results proved that, condition content over 80% is best parameter to promote theβ-Sialon powder production. Compared other kinds temperature, 1430 °C optimal...
PZ-30 excavator is a small tonnage miniature excavator. Due to the need of working condition, this machine should be long-term mount hydraulic breaking hammer. In order reduce damage on boom caused by vibration and optimize design boom, it needed conduct modal analysis boom. This paper uses Algor finite element simulation software, combined with actual environment excavator, 3D model. paper, calculates five orders resonance relates main shape vibration. Thus, can provide advice for use...
The widespread adoption of renewable energy plays a crucial role in achieving the Sustainable Development Goals low carbon power system. To effectively manage and control distribution network system promote integrated coordination, two-layer optimization model is proposed. This
The detection and repair of cable faults can provide a strong guarantee for the continuous high quality supply power communication, especially soft prevent system accidents is great significance to maintain stability, safety reliability operation. Currently there are no technical difficulties in detecting locating hard cables, but cables still greater challenge. In this paper, transmission line model introduced, calculation process each distribution parameter given with RG58-SYV-50-3 coaxial...
