uca造句
1. A fading correlation model considering antenna spacing, scattering angel and the amount of delay spread was constructed assuming uniform circular antenna (UCA) at the receiver side. 2. Dorsal view of a female Uca formosensis, a white band frequently exists on the posterior carapace. 3. The mathematical relationship between the scattering of UCA and Bmode video intensity was set up on the basis of Bmode imaging principles. 4. The UCA500R1 keyword plus any attributes form a UCA collation name. 5. The local boys on the island called Raina, "Uca" – pronounced "oo-tha" and literally translated as "rain". 6. The burrow depth of Uca formosensis reaches approximately one meter in the high intertidal zone. 7. Since the default UCA cannot cover the collating sequence of every language supported by Unicode at the same time, the ordering of characters can be customized using optional attributes. 8. The Unicode Collation Algorithm (UCA), the core standard for sorting all text, is also being updated at the same time (see http://www.unicode.org/reports/tr10/). 9. Method The relationship between perfusion parameter and UCA bubble concentration in imaging plane was described by stochastic differential equation. 10. The default UCA ordering sorts only a few languages such as English and Italian properly, according to the expectations for users of these languages. 11. Adopting direct array manifold in a uniform circular array (UCA), the estimation of Doppler frequency can be obtained by DOA matrix. 12. Firstly,[/uca.html] the data model and statistic model of UCA are introduced. 13. In the end, we discuss the direction finding algorithms of UCA for the coherent signal sources and the wide-band cyclostationary signal sources, respectively. 14. There is a theoretical possibility that the interaction of diagnostic ultrasound and UCA could produce bioeffects. 15. The alternate attribute controls the handling of variable characters in the UCA: white space, punctuation marks, and symbols. 16. The Manufacturing Message Specification(MMS) technique, Field Device models and Inter Control Center Communication Protocol(ICCP) models are explained. The characters of UCA are provided. 17. Using a customized collation for the database may have an impact on the query performance since the number of possible string matches increases when you choose a looser UCA setting. 18. The basic principle, usage of air blowing based level detection, and the structure and application of UCA(H) type nuclear safety class air blowing device are described briefly. 19. Computer simulation results show that for small spacing the UCA yields higher channel capacity than ULA. 20. Firstly, the mode excitation method is used to transform the manifold matrix of UCA into one with a form similar to that of a uniform linear array (ULA). 21. This article analyses the background, basic ideas, and the content of IEC61850 standard series, including UCA standard, object-oriented modeling, system and project management, etc.
