摘牌是指一家公司在证券交易所上市后，由于某种原因被交易所取消上市资格，停止交易的过程。摘牌的原因有很多种，比如公司经营不善、财务状况恶化、股价异常波动等等。一旦公司被摘牌，其股票将无法在交易所继续交易，投资者将面临巨大的损失。

英文：Delisting refers to the process of a company's shares being removed from trading on a stock exchange due to various reasons such as poor business performance, deterioration of financial condition, abnormal stock price fluctuations, etc. Once a company is delisted, its shares cannot be traded on the exchange any longer, which may result in huge losses for investors.

摘牌对于投资者和公司都有很大的影响。对于投资者来说，如果他们持有的股票被摘牌，他们的投资将无法通过二级市场变现，这将给他们带来巨大的经济损失。此外，摘牌也可能会影响投资者的信心和信任，使他们不再愿意投资该公司的股票。对于公司来说，摘牌可能会导致融资渠道受限、声誉受损、股价下跌等一系列问题，这将对公司的经营和发展产生不利影响。

英文：Delisting has significant impacts on both investors and companies. For investors, if the shares they hold are delisted, their investments will no longer be able to be liquidated through the secondary market, which can result in significant financial losses. Additionally, delisting may also affect investors' confidence and trust, making them reluctant to invest in the company's shares. For companies, delisting may lead to a series of problems such as restricted financing channels, damaged reputation, and falling share prices, which can have adverse effects on the company's operations and development.
