In the previous fiscal year, the research endeavor faced challenges. The main issue was the constrained time assigned to the Principal Investigator (PI). The limited time, despite unwavering dedication, hampered exhaustive research and significant findings. The PI's need to juggle other duties impinged on the project's focus.This scenario emphasizes a PI's time significance in accomplishing research goals as laid out in the funding application. Revising the time allocation is fundamental for future progress and catalyzing substantial discoveries.Despite these difficulties, we maintain optimism regarding future improvements. We foresee that adjusting the PI's time allocation, supplemented by the assistance of other team members, will constructively shape our research course.

在上一个财政年度，研究奋进面临挑战。主要问题是分配给主要研究者（PI）的时间有限。尽管有坚定不移的奉献精神，但时间有限，妨碍了详尽的研究和重大的发现。PI需要兼顾其他职责，这与项目的重点有关。这种情况强调了PI在完成资金申请中规定的研究目标方面的时间重要性。修改时间分配对未来的进展和催化实质性发现至关重要。尽管存在这些困难，我们对未来的改进保持乐观。我们预见，调整PI的时间分配，辅之以其他团队成员的协助，将建设性地塑造我们的研究课程。
