| 中文摘要： |
为了解决现行键盘布局在中文拼音输入情景下效率低的问题，需要构造一种新的中文拼音键盘布局。本文创新地将汉语拼音视为一种特殊的语言，验证其对奇普夫定律的实用性，证明了26个汉语拼音字母也符合奇普夫定律的设定，满足省力原则，从而从统计理论基础上说明使用大样本来研究汉语拼音分布规律的正确性，避免了因为难以进行随机抽样而导致的样本选取不佳的问题。在依据字母的分布频率高低排列主要键位后，本文通过计算一步后移的条件概率来测度字母间的关系，从而依据这种关系进行剩余字母的排列。为了测试新布局的效果，本文构建了指尖移动时间统计指标，利用统计模拟方法模拟打字输入的过程，最终得到的测试结果显示新布局的效率提升在23%以上。

| 外文摘要： |
In order to solve the problem that the current keyboard layout is inefficient under the Chinese Pinyin input scenario, a new Chinese Pinyin keyboard layout needs to be constructed. This article innovatively treats Chinese pinyin as a special language and verifies its practicability to Zipf ’s law. It proves that 26 Chinese Pinyin letters also conform to the setting of Zipf’s law and meet the principle of labor saving. On the basis, it is explained that the use of large samples to study the distribution of Chinese Pinyin is correct, which avoids the problem of poor sample selection caused by the difficulty of random sampling. After the main key positions are arranged according to the distribution frequency of the letters, the relationship between the letters is measured by calculating the conditional probability of one step backward, so as to arrange the remaining letters according to this relationship. In order to test the effect of the new layout, this paper constructs a statistical index of fingertip movement time and uses statistical simulation methods to simulate the process of typing input. Finally, the test results obtained by this indicator show that the efficiency of the new layout is improved by more than 23%.
