The aim of spatial sound or spatial audio is to reproduce the spatial information of sound,so as to recreate the desired spatial auditory events or perceptions. Recently, spatial sound becomes a hot topic in the fields of acoustics, signal processing, and communication. A series of spatial sound techniques have been developed and applied to a wide area of scientific research, engineering, and amusement. The history, principle, progress and applications of spatial sound technique are comprehensively reviewed in this article. Especially, spatial sound techniques based on different principles are united within the framework of spatial sampling and reconstruction theorem of sound *** challenges and prospects of spatial sound are also addressed.

A novel multi-baseline phase unwrapping algorithm based on the unscented particle filter for interferometric synthetic aperture radar （INSAR） technology application is proposed. The proposed method is not constrained by the nonlinearity of the problem and is independent of noise statistics, and performs noise eliminating and phase unwrapping at the same time by combining with an unscented particle filter with a path-following strategy and an omni-directional local phase slope estimator. Results obtained from multi-baseline synthetic data and single-baseline real data show the performance of the proposed method.

This paper presents an enhanced multi-baseline phase unwrapping algorithm by combining an unscented Kalman filter with an enhanced joint phase gradient estimator based on the amended matrix pencil model, and an optimal path-following strategy based on phase quality estimate function. The enhanced joint phase gradient estimator can accurately and effectively extract the phase gradient information of wrapped pixels from noisy interferograms, which greatly increases the performances of the proposed method. The optimal path-following strategy ensures that the proposed algorithm simultaneously performs noise suppression and phase unwrapping along the pixels with high-reliance to the pixels with low-reliance. Accordingly, the proposed algorithm can be predicted to obtain better results, with respect to some other algorithms, as will be demonstrated by the results obtained from synthetic data.

清代蜀中第一诗人张问陶,今存诗三千余首。他自15岁作诗,28岁时已呈现独特的艺术个性,其后期的感怀、题画和哲理诗均达于新的境界。他虽与性灵派诗人袁枚有交谊,同宗性灵,论诗亦同,但却具有自己的风格。袁枚诗浮滑纤佻,张问陶诗并无此弊。他情感沉郁,意象新奇,流畅豪放,颇具空灵奇崛的艺术特征,因此在众多清代诗人中能独树一帜。

植物激素对棉花蕾铃脱落的调控研究进展

棉花蕾铃脱落是一个普遍存在的现象,有对逆境环境胁迫的主动适应性脱落,也有因品种遗传特性、环境条件、栽培措施以及生物和非生物胁迫被动的受损脱落。蕾铃脱落直接影响着棉花的产量,国内外现有公开报道多集中于20世纪50、60年代关于乙烯和脱落酸对棉花蕾铃脱落影响的初步发现。结合其他植物的研究结果来看,蕾铃脱落似乎与生长素、赤霉素和细胞分裂素等促生长类激素的下降以及乙烯和脱落酸等抑制生长类激素的升高密切相关,激素在植物体内不仅介导新陈代谢过程,还协调着与信号通路相关的调控因子,在脱落过程中起着关键作用。本文从植物激素调控入手,综述了近年来包括脱落区形成和作用的分子调控机制以及各激素在棉花蕾铃脱落以及其他植物(生殖)器官脱落过程中的响应和调控机制等。发现目前以棉花蕾铃脱落为对象的研究非常匮乏,且多集中于少数激素对棉花生殖生长影响的有限研究,缺乏对导致蕾铃脱落的深层次机制的探究和解析。因此,未来研究方向应着重于探究棉花蕾铃脱落的遗传基础、发掘新的抗脱落基因资源和培育抗脱落棉花品种,同时加强在以棉花为模型植物下,蕾铃脱落与植物激素调节的关系研究,为提高棉花产量提供理论依据和技术支持。
