一 |     近日，河南省力量钻石股份有限公司实现重大技术突破，成功培育出247.82克拉超大颗粒培育单晶，再度刷新世界纪录。    

The U.S. tallied about 15,000 reported hospitalizations of people with COVID-19 over the seven days ending Aug. 19. Though a far cry from previous totals during the pandemic, that’s a 19% increase from the week prior, continuing a climb that started at the end of June after hospitalizations reached a recent weekly low point of approximately 6,300.
Relative to population, the latest tally equates to 4.5 people per 100,000 admitted to the hospital. By state, Hawaii and Florida saw the highest rates of new COVID-19 hospitalizations, at 9.8 and 9.7 per 100,000, respectively – more than twice the national rate. Louisiana (6.6), Alabama (6.5) and Mississippi (6.5) had the next-highest rates.
Among patients visiting emergency departments, 1.9% were diagnosed with COVID-19 nationally. Hawaii and the southeastern states of Mississippi, Florida, Alabama and Louisiana saw shares higher than 3%.
Seven counties were described by the CDC as having a “high” level of COVID-19 hospital admissions, with rates of 20 per 100,000 or higher. Several counties in Mississippi – Noxubee, Lowndes, and Clay – as well as Lamar County, Alabama, were reported to have seen 26.4 new hospitalizations per 100,000 people. Another 117 counties were said to have a “medium” level of COVID-19 hospital admissions – with rates between 10.0 and 19.9 per 100,000 people.
Notably, the CDC’s county hospital admission figures are calculated at the Health Service Area level, which can span multiple counties. This means counties within the same HSA will share the same admission rates in the data.
The counties with the highest rates of COVID-19 hospital admissions per 100,000 people were:
        
  1. Lamar County, Alabama - 26.4
    2.     
  2. Clay County, Mississippi - 26.4
    3.     
  3. Lowndes County, Mississippi - 26.4
    4.     
  4. Noxubee County, Mississippi - 26.4
    5.     
  5. Fisher County, Texas - 25.8
    6.     
  6. Mitchell County, Texas - 25.8
    7.     
  7. Nolan County, Texas - 25.8
    8.     
  8. Jefferson County, Georgia - 19.6
    9.     
  9. Washington County, Georgia - 19.6
    10.     
  10. Claiborne Parish, Louisiana - 19.1
    11.     
  11. Fillmore County, Nebraska - 19.1
    12.     
  12. Thayer County, Nebraska - 19.1
    13.     
  13. Stevens County, Kansas - 18.2
    14.     
  14. Furnas County, Nebraska - 17.6
    15.     
  15. Harlan County, Nebraska - 17.6
    16.     
  16. Phelps County, Nebraska -  17.6 
    17.     
  17. Rutland County, Vermont - 17.2
    18.     
  18. Foard County, Texas - 16.8 
    19.     
  19. Hardeman County, Texas - 16.8
    20.     
  20. Wilbarger County, Texas - 16.8
    21.     
Because hospitalization rates are calculated per 100,000 people, it’s worth noting that even a relatively small number of hospitalizations in a small community can lead to a higher hospitalization rate.
Other measures also can give a sense of the current state of COVID-19. Though the CDC has ceased publishing a "community level" metric that incorporated COVID-19 case rates and hospital admissions – as well as the average percentage of hospital beds occupied by COVID-19 patients – health departments can submit the results of their sampling of wastewater for the virus to the CDC via the National Wastewater Surveillance System.
Since the U.S. passed 1 million cumulative deaths tied to COVID-19 in the spring of 2022, more than 138,000 additional people have died in connection with the disease, according to provisional data from the CDC.
While the latest tallies are down from a recent peak of about 3,900 deaths in a week in January – and well below the maximum peak of around 26,000 deaths per week in early 2021 – data indicates hundreds of people have died in connection with COVID-19 of late. Maryland and Florida each saw 3.4% of their total deaths attributed to COVID-19 during the week ending Aug. 19, doubling the national percentage.
。2025年，该企业曾研制出156.47克拉培育单晶，创下阶段性行业纪录。

二 | 时隔不足一年，企业实现技术量级跨越式提升，大幅刷新超大颗粒培育单晶重量纪录，进一步巩固了企业在国内超大颗粒单晶培育领域的龙头引领地位。据企业项目办公室负责人陈亚男介绍，本次产出的超大单晶尺寸达45毫米×43毫米，规格接近2英寸行业标准尺寸。企业依托自主研发的外延生长技术，成功攻克2英寸籽晶制备核心技术瓶颈。此次技术攻坚取得的重大成果，标志着柘城县超大颗粒单晶培育工艺日趋成熟、生产体系规范完善，为大尺寸金刚石功能材料规模化量产与产业化应用筑牢坚实技术根基，充分彰显了我国培育钻石产业强劲的科技创新实力。企业单点技术突破，是我国培育钻石产业整体跃升的生动缩影。

三 | 当前，我国培育钻石产业迈入高质量发展快车道，依托成熟的合成工艺、完备的产业链配套和规模化产能优势，稳居全球产业核心地位，国内培育钻石毛坯产能占全球总量80%以上，是全球规模最大的培育钻石生产基地。

四 | 但长期以来，行业专属标准化体系缺位，成为制约产业规范化、专业化、可持续高质量发展的突出短板。为有效破解行业发展痛点、补齐产业配套短板，今年4月，由中国珠宝玉石首饰行业协会培育钻石分会牵头，珠宝国检实验室、中南钻石、黄河旋风、力量钻石等多家行业龙头企业联合编制的国内首份《培育钻石毛坯分级》团体标准（T/GAC 32-2026）正式落地实施。作为国内培育钻石毛坯细分领域首个专项分级标准，该标准填补了行业标准化建设空白，终结了行业长期存在的分级、定价、规范不统一乱象，推动产业从粗放式规模扩张，全面向品质化、标准化、高端化方向转型升级。

五 | 全新团体标准紧密贴合培育钻石毛坯专属产品特性与市场交易实操需求，构建起六大维度全流程系统化分级体系，实现分级实操、品质判定、计量定价、报告输出全链条标准化管控。

六 | 标准明确了分级人员资质与检测环境规范要求，从源头保障分级结果的专业性与权威性；针对性搭建适配高温高压法（HPHT）、化学气相沉积法（CVD）两种主流工艺的颜色、净度分级规则，精准区分不同工艺毛坯的内外特征，彻底破解传统标准适配性不足的行业难题。该标准的核心创新亮点，是首次引入“预估质量”“出成率”核心评价指标，搭建培育钻石毛坯专属出成率分级体系，建立科学量化的毛坯价值评估机制，补齐了行业长期存在的价值判定无量化标准短板。同时，标准统一了质量计量方式，规范了分级报告格式、内容及综合评级体系，让毛坯品质判定、市场定价有标可依、有据可查，从根源上解决行业分级随意、定价无序问题，为市场公平交易、精准价值评估筑牢标准化根基。

七 | 业内专家表示，《培育钻石毛坯分级》团体标准的实施，是国内培育钻石产业标准化建设从“0”到“1”的里程碑式突破。统一的全国性分级判定尺度，推动行业形成“同品同质、同质同价”的良性发展共识，有效规范市场交易秩序、减少行业交易纠纷、全面提升产业市场公信力。专属自主标准化体系的建成，让国内培育钻石产业彻底摆脱对天然钻石标准的依赖，构建起适配本土产业优势、接轨全球市场的现代化标准化发展体系。在产业国际化战略布局层面，该标准具备重要的核心支撑作用。当前，郑州培育钻石国际交易中心正加快构建公开、公平、公正的行业价格发现机制，统一规范的毛坯分级标准，是价格机制高效、精准、稳定运行的核心技术底座。新标准的落地实施，将助力行业构建市场化、标准化定价体系，推动我国从培育钻石产能大国，向掌握行业核心定价话语权的产业强国跨越，持续巩固我国在全球培育钻石产业链、供应链、标准链中的核心主导地位。随着培育钻石合成技术持续迭代更新，新型生产工艺、创新产品形态不断涌现，行业发展态势日新月异。后续，行业将结合标准落地后的实操应用经验，广泛收集市场、企业、检测机构的反馈建议，持续推进标准修订优化与动态升级，精准适配产业技术革新与市场发展需求，持续以标准化建设赋能产业高质量、可持续发展，推动国内培育钻石产业实现全方位、多层次的跨越式升级。（左 鲤）。
