The results indicate that the precipitation rate of phosphoric acid is larger than 99% under the conditions of 2530 ℃, the mole ratio of trimeric cyanamide to phosphoric acid 21, two-step precipitation by trimeric cyanamide divided into two portions and separately stirring 60 min.

研究结果表明：在25~30 ℃、三聚氰胺与磷酸摩尔比为21、三聚氰胺分成两份进行两步沉淀、各搅拌60 min为三聚氰胺沉淀磷酸的最佳条件，在此条件下磷酸沉淀率大于99%；在磷酸三聚氰胺沉淀中夹带的氯化钙在固液质量比15、温度40 ℃和搅拌60 min下用水反复洗涤3次后可被完全去除；再将净化后的磷酸三聚氰胺与氨水反应，制得了符合GB 10205—2001标准的磷酸一铵和磷酸二铵产品。

Since is nation don't need check product, such honor, beyond all doubt is because three deer companies must own very complete examination organization and means, and let the nation trust, that since it is so, we can guess and affirm, now that be subjected to impossibly surprised of"pollution", that is to intentionally add three chlorine cyanotype An, if is so, that circumstances severity, even can calculate previous for the sake of business enterprise benefits cupidity smoked under the heart of premeditated murder, for the sake of lane pure why three deer companies want to intentionally add three chlorine cyanotype An products that the poison harms a baby kid, we understand first once what is three chlorine cyanotype An

既然是国家免检产品，如此荣誉，毫无疑问是因为三鹿公司本身一定就拥有相当完备的检测机构和手段，并让国家放心，那既然如此，我们可以猜测和认定，既然不可能是受到了意外的"污染"，那就是故意添加了三氯氰胺，如果是这样，那事态就严重了，甚至可以算得上一种为了企业利益利欲熏心下的谋杀，为了弄清为什么三鹿公司要故意添加毒害婴幼儿的三氯氰胺制剂，我们先了解一下什么是三氯氰胺

The forward kinematics is analyzed by choosing one of the mechanisms which have one, two,three or zero angle constraint.Wherein,3-CCC is a new parallel mechanism which has three angle constraints and three distance constraints, Calay\'s formular and direction cosine matrix are used to describe the rotation matrix respectively.By setting Dixon\'s and Sylvester\'s resultant with the three angle constraint equations respectively and using parameters replacement to deal with the distance constraint equations,the 64 order input-output equation of the forward kinematics is obtained under both of the methods.Numerical example confirms these theretical results and the motion simulation is shown in VC++ by integrating OpenGL.

3对高小山提出的广义并联机构进行了研究，以其中具有角度约束的并联机构进行了分析，选取具有一个、两个、三个和零个角度约束类型中各一个机构进行了运动学正解求解，其中3-CCC是一种全部由圆柱副构成的具有三个线线角度和三个距离约束的新型并联机构，文中分别用Calay公式和方向余弦两种旋转矩阵建模方法对其位置正解进行了分析，通过对三个角度约束方程分别构造Dixon结式和Sylvester结式，以及对三个距离约束方程进行变量代换分别导出了位置正解输入输(来源：4040ABC论文网www.abclunwen.com)出方程，得出64组位置正解，并使用数值算例验证了其全部根。

The crystal structure of trioxane was accurately determinated. By using the crystal structure model of trioxane, the ring-opening polymerization mechanism of trioxane by γ-irradiation may be fairly well explained. Polyoxymethylene obtained by solid state polymerization of trioxane may have two types of molecular chains with different orientations, one parallel to the C...

我们精确测定了三聚甲醛的晶体结构，利用三聚甲醛晶体结构模型，可以很好地阐明三聚甲醛在受到γ射线辐照后开环聚合的机理，由三聚甲醛晶体固相聚合得到的聚三聚甲醛，应该有两种不同取向的分子链，一种与三聚甲醛的c轴平行；另一种与c轴成75°37′的交角。
