近四千万元入账专户 八个小区上线“晒明白账” 钱塘白杨街道探索小区公共收益监管新模式_我的网站

一 |     8月5日，一场关于住宅小区公共收益全流程监督工作的调研暨人大代表评议会，让钱塘区白杨街道的一个改革举措走进公众视野：两个月前，惠邻住宅小区公共收益账务服务中心在该街道注册成立，这也标志着“业账街管”全流程闭环监督正式落地。走进白杨街道一楼的账务服务中心，一名财务专员正在逐笔核对各试点小区的收支凭证。

Chinese astronomers have discovered that the Milky Way is not a simple, smoothly warped disk, but contains widespread "wrinkle-like" structures resembling ripples on a water surface, providing new clues to understanding the galaxy's 3D structure and evolutionary history.
The discovery was made by a research team from the Purple Mountain Observatory (PMO) under the Chinese Academy of Sciences, using data from the "Milky Way Imaging Scroll Painting" (MWISP) survey. The findings were published online titled "Widespread corrugations superimposed on the Galactic warp in the outer CO disk" in the journal Nature Astronomy on August 7.
For decades, astronomers have known that the Milky Way's disk is not perfectly flat. Instead, its outer regions are slightly bent upward on one side and downward on the other - a structure known as a galactic warp.
However, the latest study shows that this large-scale bending is not the whole story. Smaller-scale vertical fluctuations are also embedded within the warped disk, creating a more complicated 3D structure.
"In many illustrations and in the public imagination, the Milky Way looks like a flat vinyl record," Sun Yan, associate researcher at PMO and the first author of the paper, told the Global Times on Tuesday. "In reality, the outer part of the Milky Way is more like a record that has been heated and deformed, with one side lifted and the other side lowered. That is the warp. On top of this large-scale deformation, there are additional smaller waves, which we call corrugations," Sun explained.
Using a more everyday analogy, Sun compared the Milky Way's structure to a sea surface. The warp is like a large swell that changes the overall height of the ocean, while corrugations are smaller waves superimposed on that swell.
"The two structures exist together. In our data analysis, we first removed the large-scale warp model, which allowed us to reveal the smaller wave-like patterns hidden underneath," Sun said.
The research focused on the Milky Way's outer gas disk rather than the more familiar stellar disk. According to Sun, cold molecular gas and stars provide two complementary ways to study the galaxy.
"Molecular gas is a sensitive probe for studying the vertical structure and dynamics of the galactic disk because it is concentrated near the disk plane and responds strongly to disturbances," she said.
Molecular gas is also the raw material for star formation, meaning its distribution is closely connected with the formation of young stars. The researchers traced this gas through carbon monoxide (CO) emission, which can penetrate regions obscured by interstellar dust and provide a different perspective from optical observations of stars.
The breakthrough was made possible by the MWISP survey, conducted using China's 13.7-meter millimeter-wave telescope. 
"MWISP can be understood as giving the Milky Way a large-scale medical examination using millimeter-wave observations," Sun said.
Previous CO surveys were limited in sensitivity and coverage, making it difficult to accurately study the distant outer regions of the galaxy. In contrast, the latest study identified more than 30,000 molecular cloud samples, covering about half of the Milky Way's outer disk and extending to a distance of about 26 kiloparsecs from the Galactic center.
With such a large dataset, researchers were able to first establish a model of the overall warp and then separate subtle structures from the background. The newly identified corrugations have radial wavelengths of about 3.9-7.9 kiloparsecs and vertical amplitudes of about 100-200 parsecs.
The study also identified a corrugation structure extending about 40 kiloparsecs in azimuth at a distance of around 12.7 kiloparsecs from the Galactic center. In some spiral arm regions, vertical displacements can reach approximately 200 parsecs.
The researchers believe these large-scale vertical fluctuations are likely related to "bending waves" triggered by external gravitational disturbances, suggesting that the Milky Way might have experienced more complex interactions during its evolutionary history.
Although the newly discovered structures sound dramatic, they do not have any direct impact on Earth or the solar system. "Humans cannot directly sense these corrugations," Sun said. "Their scales reach thousands or even tens of thousands of light-years, and even if these structures are evolving, such changes would not be directly perceptible on human timescales."
The study focuses on the outer disk of the Milky Way and does not include the region around the solar system. "There is currently no evidence that these structures have any observable influence on Earth's environment," Sun said.
Instead, their significance lies in what they reveal about the past. Like geological layers recording Earth's history, these galactic structures preserve traces of the Milky Way's evolutionary journey, the researchers explained.
Researchers said future studies combining more precise motion measurements and numerical simulations could further reveal the origins of these structures and their role in the long-term evolution of the Milky Way.
。这里，正是“业账街管”体系的核心枢纽。白杨街道是钱塘区唯一的城市型街道，服务中心负责人宋扬在评议会现场算了一笔账：辖区62个住宅小区公共收益总规模超过1.2亿元，平均每个小区200多万元。早在2024年，白杨街道77%的住宅小区已有代理记账，但当时由27家代理记账机构提供服务，账务处置流程不统一、不规范，存在监督盲点。如今，街道推出“七个统一”全流程闭环监督模式：统一代理记账，通过公开招标、出资选聘优质机构；统一专户管理，所有有公共收益的小区必须开设专用账户，实行“一小区一账户、一户一档备案”，从源头杜绝资金“体外循环”。宋扬现场演示了系统流转过程：以朗琴社区梦琴湾小区为例，7月20日，业委会工作人员王端提交了地下室污水井排水泵项目申请，经业委会财务负责人、业委会主任、社区工作人员逐级流转，全过程在系统上清晰展示，最终费用35655元，每一个环节都有迹可循。朗琴社区书记张璐对此深有感触：“以前梦琴湾小区公共收益分散在4个银行账户，管账都是业主兼职。今年7月注销了所有账户，现在街道统一管，审批步骤全程可追溯。目前一共办结了8笔，涉及资金20万元。”碧桂园小区两届业委会主任许国强服务着一个1800多户的小区。在他看来，这样的做法“比较妥当”：“所有收支凭证都要经业委会初审、社区复核、街道备案，可以有效堵住财务管理的漏洞。”截至今年7月，12个试点小区统一记账服务接入已全部完成，账户余额合计约3950万元，其中8个小区已正式上线“幸福E本账·白杨幸福家”数字系统。制度之变，感受最深的是居民。

二 | 多蓝水岸小区一位居民代表王女士告诉记者，前些年小区商铺租金、公共车位等账目不透明。第六届业委会成立后，在社区全程指导和常态化监督下，小区形成规范的资金管理制度。王女士说，现在多蓝水岸小区已完成监控升级、消防设施维修更新、儿童游乐区提升等项目，单元门禁升级和内墙粉刷也在有序推进。账目透明、业委会履职能力提升，业主的满意度自然稳步提高。去年，白杨街道41个存续业委会全部参评“最美业委会”，23个小区获评。

三 | 其中，连续三年获评的有6家，均可获得街道给予的100万元项目补助资金。

四 | 东郡社区锦湾小区业委会主任蒋军辉告诉记者，小区获得的100万元项目补助资金已经到位，其中20万元用于楼道环境提升改造，80万元准备用来提升改造消防设施，“钱花在哪里、怎么花，每一步都在系统上留痕，业主看得清清楚楚，自然就支持。”参加评议会的多位人大代表对这一模式给予肯定。来自浙江金融职业学院的钱塘区人大代表叶健表示：“目前来看挺好。

五 | 建议权责边界进一步厘清——公共收益所有权归业委会，街道负责监督管理，过程中一定要做到信息公开公正。

六 | ”白杨街道也提出了一个小目标：今年力争将这一模式覆盖到21个小区。
