博士（doctoral）一词是英语中描述与博士学位相关事物的形容词，常用于学术语境，例如doctoral thesis（博士论文）、doctoral degree（博士学位）、doctoral program（博士项目）等。以下是一些典型的doctoral造句示例：1. She completed her doctoral research on climate change. 2. Many universities require a doctoral defense for graduation. 3. He was awarded a doctoral fellowship. 4. The doctoral candidate presented his findings at the conference. 5. Her doctoral dissertation was published in a top journal. 注意，在实际使用中，doctoral通常修饰名词，表示“博士的”或“与博士相关的”。
