📝 摘要字数统计（投稿字数限制检查）Abstract Word Counter (Word Limit Check)
粘贴论文摘要，按投稿系统常见规则统计英文词数和中文字数，对照 150、200、250、300 词等字数上限显示进度条和剩余字数，可忽略 LaTeX 命令和公式，同时统计句子数和字符数。Paste an abstract to count English words and Chinese characters as submission systems do, with a progress bar against 150/200/250/300-word limits and the words remaining, LaTeX commands and math ignored, plus sentence and character counts.
英文按空格分词计数（连字符词算 1 个），中文按字计数。不同投稿系统的计数方法略有差异，建议留出几个词的余量。English is counted by whitespace-separated words (hyphenated words count once); Chinese by characters. Submission systems count slightly differently, so leave a few words of margin.

如何使用「摘要字数统计（投稿字数限制检查）」？How do I use the Abstract Word Counter (Word Limit Check)?
选择字数上限（或输入自定义数值），粘贴摘要，进度条接近上限时变黄，超出变红。摘要里有 LaTeX 命令时保持勾选“忽略 LaTeX 命令和公式”，公式会按 1 个词计算。Choose or type a limit and paste the abstract; the bar turns yellow near the limit and red above it. Keep “Ignore LaTeX” ticked so each formula counts as one word.
连字符单词算几个词？How are hyphenated words counted?
像 “state-of-the-art” 这样的连字符词算 1 个词，与 Word 和大多数投稿系统一致。Hyphenated words like “state-of-the-art” count as one, as in Word and most submission systems.
