白银--兼备优良工业属性的贵金属。白银的化学符号为 Ag，源自拉丁文 Argentum，意为“浅色、明亮”。 高纯度白银外观为白色，质软，且有金属光泽，但掺杂杂质后会变硬，颜色可能呈灰、红色。白银历史悠久，其作为货币和价值储藏手段距今已有四千多年的历史。由于白银具有良好的电热传导特性、较高的感 光性和发光性，白银被广泛应用于电子电器、感光材料和化学化工等领域中，如光伏和摄影需求。同时，高反射率使得白银色泽明亮，叠加化学稳定性使其易于保存，白银被广泛用于制作首饰、装饰品、银器、餐具、奖章和纪念币等。

MDI 是化工品种技术壁垒最高的产品之一，全球呈现寡头垄断格局，主要产能和核心技术基本掌握在四家海外巨头(巴斯夫、科思创、亨斯迈、陶氏)和国内企 业万华化学手中，五家企业合计产能占比超 90%。本文，我们将从五大聚氨酯生产企业近年的财务情况出发，展望未来三年聚氨酯的供需格局与发展趋势。

2021 年以来，中国人形机器人政策重心由技术开始转向产业化。2012 年以来我 国政策持续推动人形机器人发展，并且从 2021 年开始，中国人形机器人政策重心由技术开始转向产业化。2023 年 10 月，工信部印发《人形机器人创新发展指导意见》，规划到 2025 年人形机器人创新体系初步建立，培育 2-3 家有全球影响力的企业，打造 2-3 个产业发展集聚区；到 2027 年，人形机器人技术创新能力显著提升，形成安全可靠的产业链供应链体系等。

The ground based aircraft and missile defense systems are used to effectively track, detect, intercept, and neutralize all kinds of air threats posed by combat projectiles, missiles, aircraft, rockets, and UAVs. These systems have the capability to defend a country from all incoming airborne threats.

Grass-fed beef comes from cows raised by feeding only grass throughout its lifetime. While most cattle spend most of their lives in pastures eating grass before moving to a feedlot for grain￾finishing, grass-finished cattle remain on a pasture and forage diet.

Grapeseed extract is a natural supplement derived from the seeds of grapes. It contains high levels of proanthocyanidins, which are powerful antioxidants. These compounds are known for their potential health benefits, including reducing inflammation and supporting cardiovascular health

Gluten-free food refers to food items that do not contain gluten, a type of protein found in wheat, barley, rye, and hybrids of these grains. The purpose of gluten-free diets is to avoid triggering adverse reactions in individuals with gluten-related disorders, such as celiac disease, gluten sensitivity, or wheat allergy. People following a gluten-free diet need to ensure that their food does not contain any gluten ingredients or any cross-contamination from gluten￾containing products.

Glass tableware includes general glassware items such as storage ware and bakeware. They are for household purposes as well as those used in the hotel/food catering industry.

The global geotechnical engineering market is a part of the global construction and engineering market. The global construction and engineering market was valued at $5,276.41 billion in 2021 and reached $5,947.2 billion in 2023.

The global genomics market includes the use of genomics products, such as consumables and instruments and services, to study genes, genetic functions, and related technologies. Genomics addresses the study of all the genes and their inter-relationship to identify their combined influence on the growth and development of organisms. The information obtained through genomics studies is used in the identification of any variations and mutations in the genomics structure, which helps in developing diagnostic methods for genetic diseases and their targeted treatments.
