Do you know what gypsum powder is after dehydration?

　　1)五氧化二磷在低溫下織造石膏時(shí)，石膏常由脫水半水物組成，其中含有釩鈦礦可溶性硬石膏。在空氣中，脫水的半水合物水合物化并形成半水合物，可用于水化鹽二水合物石膏。

　　1) When phosphous pentoxide is used to weave gypsum at low temperature, the gypsum is usually composed of dehydrated hemihydrate, which contains soluble anhydrite of vanadium titanium ore. In the air, the dehydrated hemihydrate hydrates and forms hemihydrate, which can be used for hydrated salt dihydrate gypsum.

　　2)取水和半水合物的等溫強(qiáng)度與水化和水的等溫強(qiáng)度不同。

　　2) The isothermal strength of water intake and hemihydrate is different from that of hydration and water.

　　3)在相同的生產(chǎn)二水合物的條件下，床層等溫作用沒有差異。

　　3) Under the same conditions of producing dihydrate, there is no difference in bed isothermal effect.

　　4)碳酸晶體在一定條件下可以分化成元素的組分。半水合物的凝膠化發(fā)生得很快，這一定與它的亞穩(wěn)態(tài)和一對等溫59的不斷擺動(dòng)有關(guān)。

　　4) Under certain conditions, carbonate crystals can be differentiated into the components of elements. The gelation of hemihydrate occurs very fast, which must be related to its metastability and a constant oscillation of isothermal 59.

　　5)石膏粉的脫水水化效果與半水合物凝固肢塊、沸石、氰化鎂額部肛門晶體的脫水水化效果相同。

　　5) The dehydration and hydration effect of gypsum powder is the same as that of hemihydrate solidified limb block, zeolite and magnesium cyanide frontal anal crystal.

　　6)這種相似的情況表明，該水晶家族祖先可能由礫巖組成。

　　6) This similarity suggests that the ancestors of the crystal family may have been composed of conglomerate.

　　7)在固腔條件下不發(fā)生半水合物的自然分化;空氣濕度對半水合物的強(qiáng)度有決定性的影響。

　　7) Under the condition of solid cavity, there is no natural differentiation of hemihydrate; air humidity has a decisive influence on the strength of hemihydrate.

　　8)除了在合理箭頭和現(xiàn)實(shí)世界中存在的誤差外，在石膏問題的基礎(chǔ)研究工作中:為了達(dá)成共識(shí)，膠體化學(xué)的概念還有待進(jìn)一步的發(fā)展。

　　8) In addition to the errors in the reasonable arrow and the real world, in the basic research work of gypsum problem: in order to reach a consensus, the concept of colloidal chemistry needs further development.

　　9)如果用硝酸脫水二水石膏，所得到的半水石膏不會(huì)達(dá)到無水的程度。

　　9) If the anhydrous gypsum is dehydrated by nitric acid, the anhydrous gypsum will not be obtained.
