不能说明的

And if a poet writes of the sufferings of Niobe --the subject of the tragedy in which these iambic verses occur--or of the house of Pelops , or of the Trojan war or on any similar theme, either we must not permit him to say that these are the works of God, or if they are of God, he must devise some explanation of them such as we are seeking; he must say that God did what was just and right, and they were the better for being punished; but that those who are punished are miserable, and that God is the author of their misery-- the poet is not to be permitted to say; though he may say that the wicked are miserable because they require to be punished, and are benefited by receiving punishment from God; but that God being good is the author of evil to any one is to be strenuously denied, and not to be said or sung or heard in verse or prose by any one whether old or young in any well-ordered commonwealth.

如果诗人去描写尼俄柏丧尽儿女令石头也流泪的悲痛——这些悲剧主题在诸如此类的抑扬格诗歌中随处可见——或者去描写佩罗普斯王族的父子相残，或者去描写特洛伊战争之类的主题，那么我们不能允许诗人说这些残暴故事都是神造的孽，就算跟神有关，那也应该解释清楚来龙去脉；他应该说明神帮扶正义和真理，而那些罪人的下场都是罪有应得；而不是去描写受到惩罚的人是如何如何的悲惨，神则是炮制这些悲惨的罪魁祸首——我们是不会让诗人这么去胡编乱造的；然而诗人可以去描写邪恶之人其所以都会其悲惨的结局是因为他们必须遭受惩罚，并因他们接受神的惩罚而使大家受益匪浅；说神代表着善却又是恶的帮凶会遭到所有人的极力反对，诗文中就再也不要去传播、歌唱或者道听途说地去宣扬这些恶事了，秩序井然的联邦中人民不论老少都不应该听到这些恶事。

Through the experiments on hydration of AH in the following sulphate（Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4）, dissoluble sulfate hydrate origining from hydration process of AH affects it's hydrous rate, hydrous rate of AH does not connect with Z/R of cation in stimulation, theory that Z/R affect hydrous rate of AH does not exist. Third, hydration of AH in dissoluble sulfate complies with dissolve-nucleate -grow theory, concentration of Ca~2+ from dissolving of CaSO_4 is higher than one of CaSO_4·2H_2O, calcium sulphate dihydrite gets a motivity of crystallization. dissoluble sulfate takes the following function: double-salt or dissoluble sulfate hydrate from hydration of AH in it becomes heterogeneous particle and a kind of nucleation catalyzer, and reduces surface barrier when DH becomes crystal because the crystal of DH precedently appears in uneven place. Results indicate hydration of AH does not conform with double-salt theory, but it conform with this mechanism: dissolve-nucleate-grow, formation of DH is an uneven nucleation and crystalizaion process.

通过对CaSO_4在Na_2SO_4 、K_2SO_4 、Rb_2SO_4 、Cs_2SO_4 、(NH_4)_2SO_4溶液中水化过程，以及CaSO_4·2H_2O、CaSO_4与以上硫酸盐反应速度、产物的研究，说明复盐理论不正确；CaSO_4在（Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO_4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4）溶液中水化，水化过程中硫酸盐水合物的析晶影响着无水硫酸钙水化，与激发剂阳离子Z/R值大小无关，阳离子的Z/R参数影响水化率的规律并不存在； 3、无水硫酸钙在可溶性硫酸盐中的水化按照溶解-成核-生长理论进行，CaSO_4达到溶解平衡时Ca~2+的浓度大于CaSO_4·2H_2O溶解平衡的Ca~2+的浓度，CaSO_4·2H_2O获得结晶的驱动力，可溶性硫酸盐起到形成晶核的作用：水化过程与CaSO_4生成复盐或析出水合物所形成的细小物相，作为异质微粒使母相中存在不均匀性，这些不均匀性有效地降低成核时的表面能位垒，使CaSO_4·2H_2O晶核优先地在这些具不均匀性的地方形成，因此这些物质起成核催化剂作用。
