摘要： A system and method are provided of analyzing a response expression in a freeform format as entered by a student in response to testing and practice questions presented by a computer system. The method can include parsing the response expression into tokens stored in a response expression tree (810). The system can determine whether the response expression tree is legal based on a defined grammar structure (820). Another operation is comparing a numerical evaluation of the response expression to a numerical evaluation of a reference expression (830). The similarity between the response expression and the reference expression can then be determined by comparing the response expression tree and a reference expression tree (840). Feedback can be supplied to the student regarding the overall correctness of the response expression as compared to the reference expression, based on correctness of each response expression element and the types of errors among response elements (850).

摘要： A method and system for reducing the violence of an accidental explosive reaction of an energetic material, the method comprising: (a) obtaining a solid energetic material (18) configured for use within an energetic device (10), the energetic material comprising at least one void (22) formed therein; and (b) filling at least a portion of the at least one void (22) with an inert, incompressible material (30) configured to mechanically stabilize the energetic material (18) to prevent the void (22) from collapsing and the surface area of the energetic material (18) from increasing in the event of an insult tending to damage the energetic material (18). In one exemplary embodiment, the inert, incompressible material (30) is configured to temporarily modify the energetic device (10), meaning that the inert, incompressible material (30) is configured to be removably inserted or otherwise applied to the energetic device (10).
摘要翻译：一种用于减少高能材料的意外爆炸反应的暴力的方法和系统，所述方法包括：（a）获得构造成在能量装置（10）内使用的固体高能材料（18），所述高能材料至少包括一个形成在其中的空隙（22）和（b）用惰性的不可压缩材料（30）填充所述至少一个空隙（22）的至少一部分，所述材料构造成机械地稳定所述高能材料（18）以防止空隙（22）塌缩，并且所述表面积的能量材料（18）在侮辱的情况下增加，从而损害高能材料（18）。在一个示例性实施例中，惰性不可压缩材料（30）被配置为暂时改变能量装置（10），这意味着惰性不可压缩材料（30）被构造成可移除地插入或以其他方式施加到能量装置（10））。
