高端电动两轮车市场的 “增量空间”，值得商榷。中泰证券测算的 “一线 + 新一线城市年销量增量 660 万台”，建立在 45% 渗透率的理想假设之上，但现实是，北京、上海等特大城市公共交通体系完善，两轮车渗透率天花板仅 40%-50%，且九号已占据高端市场半壁江山，向上的增长空间几近枯竭。而新一线城市因地形、地方政策、公共交通配套的差异，两轮车保有量存在显著方差，并非单纯依靠产品升级就能实现市场渗透，九号的拓店计划在重庆、成都等低渗透率城市已遭遇明显的水土不服。
，这一点在同城约会中也有详细论述
第三十六条 社区应当建立居务监督委员会，对居民委员会工作进行监督，其成员由居民会议或者居民代表会议在居民或者社区工作者中推选产生。居民委员会成员及其近亲属不得担任居务监督委员会成员。居务监督委员会的任期与居民委员会的任期相同。
It’s also worth noting that even if alternatives superior to agar were found, scientists are reluctant to abandon established protocols (even when microbiologists do use other jellies, they often still add agar to the mix, for example, to increase the gel strength of the solid media). As agar has been the standard gelling agent in microbiology for around 150 years, an enormous infrastructure of standardized methods, reference values, and quality control procedures has emerged around its specific properties. Switching to a different medium (even a superior one) means results may not be directly comparable to decades of published literature or to other laboratories’ findings.
