Patterns with context曲线与实验背景
Keep measured diffraction data, CIF structures, metadata and notes together. Inspect the curve and calculated Bragg positions in one place.将实测曲线、CIF 结构、元数据与备注一同归档，在同一界面核对实验曲线与理论峰位。
XCHANGE · OPEN SCIENCE
From diffraction
to discovery.从一条曲线，
到新的发现。
Experimental evidence deserves a shared home. Xchange brings measured patterns, crystal structures and human review together, so the next discovery has a clearer starting point.让实验的证据，有一个共同的归处。Xchange 将实测衍射曲线、晶体结构与人工审核放在一起，让每一次探索，都有迹可循。

01 / THE PROJECT
Good data should
travel further.让好的数据，
走得更远。
Xchange means exchange: connecting individual measurements to a community of researchers.Xchange 取意 Exchange：把独立的实验测量，连接成科研社区共同的积累。
A pattern alone rarely tells the whole story. The instrument, radiation source, sample description, structural assignment and reviewer’s judgment all matter. We keep these pieces together in one portable experiment record.一条曲线，很少能独自讲清一个实验。仪器、辐射源、样品说明、结构指认，以及审核者的判断，都同样重要。我们将它们保存在一份完整、可携带的实验记录中。
The collection supports experimental powder X-ray diffraction research, teaching and careful reuse. It makes uncertainty visible and keeps a path back to the original evidence.这里面向实验粉末 X 射线衍射研究、教学与数据复用，让不确定性得到明确标注，也让使用者能够回到原始证据。
Review you can follow看得见的审核过程
Approved, pending and not-approved records stay distinct. Review feedback helps contributors make specific corrections and resubmit.已通过、待审核和未通过各有明确位置。保留审核意见，让贡献者能够针对问题修正并重新提交。
A starting point for identification辅助识别，保留判断
XMatcher proposes structural candidates for single-phase patterns using a local Materials Project library. Results still require human verification.XMatcher 基于本地 Materials Project 数据库，为单相曲线提供结构候选；匹配结果仍需人工核验。
