酸性电解水是一种具有优良杀菌性能的创新产品,已广泛应用于食品、炊具等领域的消毒以及植物病害的防治中。硅是地壳中第二大常见元素,硅作为一种重要元素在植物生长中起着重要作用。大量研究表明,硅可以降低植物的非生物性（金属毒性等）和生物胁迫,并能有效地提高植物的抗病性。本研究探讨了酸电解水配制有机硅肥在大田生产过程中的可行性、硅素在番茄中的迁移特性,研究了喷施酸性电解水配制有机硅肥对番茄样品硅含量的影响,研究了番茄抗病性和重金属（Cr、CD、Pb）含量的变化。大田试验分为三个部分:（1）酸电解水配制有机硅肥的可行性研究,包括是否能有效的提高番茄的硅含量,以及是否仍然具有较好的杀菌特性;（2）硅的迁移特性研究,验证硅素是否能有效的从老叶中转运到新叶中;（3）在优化的喷施措施下,通过喷施酸电解水配制的有机硅肥对番茄抗病性和重金属含量的影响。结果表明,在番茄上喷AC-EW配制的有机硅,在保持较高杀菌效果的同时,能有效促进Si的吸收。在Si+AC-EW的应用下,如果只处理一次,下部叶片中硅含量明显高于上、中叶,植株叶片中硅含量显著提高79.4%。从研究结果看,硅元素在番茄中的二次转运性不强,不易从老叶片中转运到新叶片中,这就要求在番茄的生产过程中打顶（短尖）后需要再喷施一次酸性电解水配制的有机硅,以保证整株番茄都具有较好的硅含量。在t250.8%和t3 66.0%下施施时,番茄叶片中Si含量较低。与对照相比,Si+AC-EW处理的番茄叶片的病斑发生最轻。番茄Cd显著降低24.3%,Cr明显降低24.9%,Pb也比对照降低42.5%。总之,酸性电解质水中溶解有机硅肥的施用能有效促进硅的吸收,硅在番茄中的二次运移能力较差。因此,建议在番茄生产过程中,用酸性电解水喷有机硅3次,种植后第一周喷施一次,定植4周后喷施一次,打顶（短尖）后喷施第三次。喷施酸性电解水配制的有机硅与仅喷施直接用普通水溶解的有机硅肥或酸性电解水相比,能有效的提高作物抗病性、增加作物的硅含量、降低重金属含量。

this survey paper provides a review and perspective on intermediate and advanced reinforcement learning(RL)techniques in process industries. It offers a holistic approach by covering all levels of the process control hierarchy. the survey paper presents a comprehensive overview of RL algorithms,including fundamental concepts like Markov decision processes and different approaches to RL, such as value-based, policy-based, and actor-critic methods, while also discussing the relationship between classical control and RL. It further reviews the wide-ranging applications of RL in process industries, such as soft sensors, low-level control, high-level control, distributed process control, fault detection and fault tolerant control, optimization,planning, scheduling, and supply chain. the survey paper discusses the limitations and advantages, trends and new applications, and opportunities and future prospects for RL in process industries. Moreover, it highlights the need for a holistic approach in complex systems due to the growing importance of digitalization in the process industries.

Bacille Calmette Guerin (BCG), which has been used since 1921 as the only vaccine against tuber-culosis (tB), protects poorly, if at all, against pulmonary tuberculosis among adults in high incident developing countries. this failure has been attributed to the possible down modulating action of t regulatory cells (tregs), which can be stimulated by environmental mycobacteria and expanded by BCG vaccination. tregs induced at the site of BCG vaccination may interfere with protection against tuberculosis. this communication describes the contribution of tregs towards dampening the efficacy of BCG and plausible approaches to countering this down modulating effect of tregs. Probably, antigen specific inhibition of the local recruitment of tregs whilst avoiding generalised disturbance of immune homeostasis could prove to be worthwhile. Alternatively, drugs with short half life may achieve more acceptable transient inhibition of tregs function than the prolonged action of monoclonal antibodies. Evolving novel safe strategies is a challenge for developing a better anti tB vaccine.

Preparation and characterization of the YBCO superconducting films by chemical solution route with polyethylene glycol (PEG200) and Cu(NO3)2 as precursors are presented. It was found that PEG200 and sucrose were novel chelates and Cu (NO3)2 was an alternative precursor for the preparation of YBCO superconducting film by chemical solution route. the precursor solution was prepared by mixing yttrium trifluoroacetate, barium trifluoroacetate, and copper nitrate in solvent of methanol with chelates including PEG200 and sucrose. YBCO films were prepared by coating the precursor solution on LaAlO3 single crystal substrate, following vacuum drying, rapid calcining, firing and oxygen annealing. the prepared films were characterized by optical microscope (om), X-ray diffraction (XRD) and scanning electron microscopy (SEM). the results showed that films were crack-free and homogeneous, stronger tendency of (00l) texture, uniform with less pore, pure c-axis orientation. the films showed good superconducting properties, with tc of 90 K and critical current density (Jc) of 1 MA/cm2 (77 K, 0 t). this work demonstrates that the developed method is a promising method for preparation of YBCO superconducting film which has a fine superconducting characterization with advantages of simple and rapid.
