32085.中间层/低热层的轻微化学成分的引力波混频和有效扩散系数
[化学原料和化学制品制造业,计算机、通信和其他电子设备制造业] [2014-08-31]
The influence of gravity waves (GWs) on the distributions of minor chemical constituents in the mesosphere-lower thermosphere (MLT) is studied on the basis of the effective diffusivity concept. The mixing ratios of chemical species used for calculations of the effective diffusivity are obtained from numerical experiments with an off-line coupled model of the dynamics and chemistry abbreviated as KMCM-MECTM (Kuehlungsborn Mechanistic general Circulation Model—MEsospheric Chemistry-Transport Model). In our control simulation the MECTM is driven with the full dynamical fields from an annual cycle simulation with the KMCM, where mid-frequency GWs down to horizontal wavelengths of 350 km are resolved and their wave-mean flow interaction is self-consistently induced by an advanced turbulence model. A perturbation simulation with the MECTM is defined by eliminating all meso-scale variations with horizontal wavelengths shorter than 1000 km from the dynamical fields by means of spectral filtering before running the MECTM. The response of the MECTM to GWs perturbations reveals strong effects on the minor chemical constituents. We show by theoretical arguments and numerical diagnostics that GWs have direct, down-gradient mixing effects on all long-lived minor chemical species that possess a mean vertical gradient in the MLT. Introducing the term wave diffusion (WD) and showing that wave mixing yields approximately the same WD coefficient for different chemical constituents, we argue that it is a useful tool for diagnostic irreversible transport processes. We also present a detailed discussion of the gravity-wave mixing effects on the photochemistry and highlight the consequences for the general circulation of the MLT.

32086.全球3D电视市场报告(2014-2018年)
[计算机、通信和其他电子设备制造业] [2014-08-30]
For the past decade, consumers' television viewing habits have been undergoing rapid changes. When 3D TV sets appeared in households in 2010, the Global TV market was already in a turnaround phase. The new entrant had to fight not only the other TV models, but also the new means of entertainment that were fast eating into the consumers' TV viewing time. In the wake of social media garnering a significant share of individuals' leisure time, all other entertainment media are trying to retain their share of individuals' limited leisure time. This has forced TV manufacturers to produce innovative models and provide a high-quality viewing experience to attract the consumers.

An LED is a semiconductor that emits visible light. LEDs were initially used as indicators in various applications. Later, they were used to display numbers in electronic meters and sign boards. Currently, LEDs are used in almost every application that uses lighting systems. The control that users have over LEDs in terms of luminescence and power consumption has made them popular in industry applications.

[电气机械和器材制造业,计算机、通信和其他电子设备制造业] [2014-08-29]
A drive is an adjustable speed device that regulates the speed and direction of motors. Adjustment is made by varying the current flow through the motor. Drives are classified into two broad categories based on the type of current: AC drives and DC drives. AC drives are used to control AC electric motors, while DC drives are used for DC electric motors. Drives are widely used in the Manufacturing industries to regulate and control electrical devices such as fans, conveyors, machine spindles, and pumps during the production process.
