Organoaluminium organonitrogen compounds, pyrolysis process, polymers copolymers, carbothermal are discussed. emphasis on recent progress.
海岸带作为连接海洋和陆地系统的特殊地理地带,与人类的生存与发展密切相关,但其自然和生态环境极其脆弱和敏感。气候变化和人类活动给海岸带环境带来了巨大压力,导致其生态环境不断恶化。随着技术的发展,近年来遥感技术已成为海岸带地理环境监测的重要手段之一,在海岸带规划、管理和保护中扮演着举足轻重的角色。本文对遥感技术在海岸带地理环境监测典型应用(土地利用/覆盖、土壤质量、植被、海岸线、水色、水深和水下地形及灾害)中的主要数据源、方法、结果和局限性进行归纳和总结,并对其未来发展提出展望。
We study the fundamental problem of sampling independent events, called subset sampling. Specifically, consider a set $n$ events $S=\{x_1, \ldots, x_n\}$, where each event $x_i$ has an associated probability $p(x_i)$. The aims to sample $T \subseteq S$, such that every is independently included in $S$ with $p_i$. A naive solution flip coin for event, which takes $O(n)$ time. However, specific goal develop data structures allow drawing time proportional expected output size $\mu=\sum_{i=1}^n...
The dynamic characteristic of pneumatic brake system is very important, so the full-parameter model was established on base technology computer simulation. Its key components include valve, relay diaphragm chamber and circuit. AMESim first introduced basis mathematical derivation. So multivariable complexity derivation, nonlinear relationship can be avoided. used for bus multi-parameter simulation design. A test-bed designed to verify accuracy model. It measure output response coordination...
Abstract Computer network technology brings people a cross-epoch change. The computer has changed from behemoth to small object that is now easy carry; the beginning, can only be used for computing, and it search all kinds of information in network, not calculate any questions, but also shop directly on Internet. development promotes continuous updating aided software. It because emergence computer-aided software traditional way interior design obviously. makes more convenient fast. This...
The temperature dependence of Mn ion magnetization and the conductivity difference versus provide phase separation evidence in Nd1-xSrxMnO3 (x=0.50, 0.51, 0.52, 0.53, 0.54, 0.55). This is different from other reports may suggest that a fully charge-ordered state exists quite narrow range; sample preparation procedure affects charge ordering. polaron effect also plays an important role explaining conductivity.
In this paper, static state and quasistatic models of quantum well channel hole sheet density SiGe pmetaloxidesemiconductor with δ doping layer are established analyzed. The relations between dopinglayer concentration, holesheetdensity undoping hickness at also discussed, the threshold voltage to thickness undoping discussed. At last, relation quantumwell gate for is
Indigenous rice, which can grow at higher altitudes, contains unique genes and genetic characteristics, but its future survival is uncertain. The conservation of indigenous rice great significance from the perspectives both germplasm resource economic value. This paper puts forward suggestions for in Yuanjiang County based on stakeholder theory results three-party evolutionary game model involving local government, enterprises or cooperatives, farmers. also provides references sustainable...
Structure, magnetic and transport properties of polycrystalline Nd0.5 Sr0.4Pb0.1Mn1-xFexO3 Com pounds were experimentally studies. Single-phase samples obtained in the range x=0.0—0.1 Fe Content. There are no appreciable structure changes for introduction Fe. Mn-site doping favous a reduction magnetic/resistive transport, at rate ～16K 6% Fe, an elevated resistivity. Metal-insulator transition disappears when content exceeds ～0.08. The enhanced effects Nd0.5Sr0.4Pb0.1Mn1-xFexO3 can be...
The operating principle of the novel three-phase parallel power factor correction is presented. corresponding hysteresis current control strategy adopted. merits can be verified by simulation results. Compared with normal PFC, easy to and only 20% energy flows through full-controlled devices.
Structural and magnetotransport properties of Fe-doped Nd0.5Pb0.5−xSrxMnO3 are investigated by means x-ray diffraction (XRD), Mossbauer spectroscopy transport measurements. Both XRD patterns spectra indicate that structural distortion decreases with Sr doping. Furthermore, it is found doping results in decrease the resistivity at room temperature increase magnetoresistance. In samples, same ratio Mn3+ to Mn4+ kept. So we would rather attribute these changes local than double exchange (DE)...
