求解,求翻译。。我自己去年搜来的弹道凝胶配方,现仍不知真假。。 禁止插楼! A SIMPLIFIED 10% ORDNANCE GELATIN PREPARATION AND TEST PROCEDUREThis is the method we use to prepare 10% ordnance gelatin solution for terminal ballistics testing of personal defense ammunition. Our procedure is similar to CCI/Speer's, but it provides additional steps and guidance obtained from our own experience.Despite cost, many people and organizations that desire to use ordnance gelatin as a test medium are intimidated by earlier published procedures, which are more complex and cumbersome than necessary. Not only is this procedure simple to follow, it provides helpful photographs and a list of sources to obtain materials and equipment required to properly prepare, preserve and cast ordnance gelatin blocks.This procedure produces one batch of 10% ordnance gelatin solution, which consists of 9 liters of water mixed with 1 kilogram of ordnance gelatin powder, and is enough to cast a single, FBI-spec gelatin block that measures 6x6x16-inches.Gelatin blocks can be recycled.
