This review addresses the growing disparity between the current state of fertilizer production in china and the evolving demands of green agriculture in the 21st century. It explores major advances in fertilizers, proposes the concept of green intelligent fertilizers and develops new strategies aligned with the principles of green development in fertilizer industry and *** intelligent fertilizers may be designed to maximize the synergistic effects among plants, soils, microorganisms, nutrient sources and the environment. This concept emphasizes the integration of industry and agriculture toward green development for entire industry chain, using an interdisciplinary approach to drive the green transformation of fertilizer industry, and promote green and sustainable development of agriculture. By bridging the gap between the current state of fertilizer industry and a growing need for environmentally responsible agricultural practices, this review highlights a path toward harmonizing fertilizer production with the imperatives of green agriculture.

RaptorQ喷泉码是喷泉码的最新研究成果,理论分析和仿真验证表明,RaptorQ喷泉码是性能最好的喷泉码,同时也是编译码复杂度最高的喷泉码。针对RaptorQ喷泉码编译码复杂度高这一问题,以国际标准RFC6330所设计的RaptorQ码编译码流程为基础,提出一种RaptorQ编译码算法的优化版本。新的编译码流程通过固定生成矩阵的方式提前计算好生成矩阵并存储,方便随时调用;通过提前列变换的方式规避多次寻找标准行和高斯消去操作,以及通过去稀疏化的方式,减少编译码过程中的矩阵乘法和异或运算。仿真比较优化前后的编译码算法,结果表明,优化后的RaptorQ码编译码流程能够在保证传输性能不变的同时,减少RaptorQ喷泉码编译码基本运算次数、缩短RaptorQ喷泉码编译码的时间,降低了编译码的计算复杂度,并保持了传输性能。

We show that the quantum-mechanical fundamental representations, say, the coordinate representation, the coherent state representation, the Fan-Klauder entangled state representation can be recast into s-ordering operator expansion, which is elegant in form and has many applications in deriving new operator identities. This demonstrates that Dirac's symbolic method can be merged into Newton-Leibniz integration theory in a broad way.

In this paper, NetSLab network platform for remote collaborative pseudo-dynamic testing, which was developed recently by a research group led by the Hunan University, is presented. Aiming at MTS system which is widely used in structural testing, the control method with acquisition board was investigated in this study to realize the communication interface between NetSLab and MTS system, and open up the remote collaborative pseudo-dynamic testing system. Using the developed testing system, a collaborative pseudo-dynamic testing on LAN was carried out successfully. The result manifests that the data transmission and collaborative control can be implemented accurately between NetSLab and MTS system, so that the usability of the testing system is validated.

The optimal model and simulating model of the Hanjiang cascade reservoirs operation with one day as its calculating period are established to coordinate the contradictions between power generating and shipping. The optimal model is solved by progressive optimality algorithm method adopting the theory of large system decomposing and coordinating. By analyzing the water allocation results obtained from six schemes, which are two cascades, four cascades and seven cascades joint operation considering shipping or not, the contradiction degree between power generating and shipping is investigated and some joint operation schemes are proposed.
