在溶液中

They were both easily to be dissolved in dilute alkali. When the pH gradually increases, the ring-opening speed of the derivative is higher than that of GB. The derivative was obviously affected by solvent and higher temperatures. When GB was dissolved in PEG, the peak of the derivative disappeared at 50 ℃ for 15 h or at 120 ℃ for 4 h. Besides the main peak of GB, there appeared a small peak with a retention time of 1.2-3.0 min after heating 4 h at 120 ℃. The result showed that the derivative was in a high energy state, and GB had a better stabilization.

溶剂和温度的综合作用对衍生物的稳定性影响更加显著，GB在聚乙二醇溶液中分别于50 ℃下保存15 h和120 ℃下保存4 h后其中的衍生物峰全部消失；将该溶液于120 ℃下保存4 h后分析，除有主峰GB外，在保留时间为1.2～3.0 min范围还伴随有小峰出现，这说明衍生物处于高能态，GB相对较为稳定，两者共存，且相互转化；在特定条件下衍生物能全部转化为GB。

The existence of dextran sulphate to the native ovalbumin leads to decrease about 60％ in fluorescence intensity following high pressure treatment. Complexation of polysaccharide with ovalbumin seems to protect the protein against pressure induced conformational change and aggregation; The presence of τ-carrageenan in glycinin solution is also found to protect the protein against pressure.

经超高压处理后，加入硫酸右旋糖苷的鸡蛋清蛋白溶液中的ANS荧光强度显著降低，降低约60％；这表明，硫酸右旋糖苷的加入可以和鸡蛋清蛋白相互作用，从而在超高压处理中起到稳定蛋白质天然构象的作用；对于大豆豆球蛋白溶液而言，ι-角叉菜胶的加入有维持高压下大豆豆球蛋白构象稳定性的作用。

Where α is the rotation angle read on the polarimeter, C is the concentration of the semicarbazone solution in grams per milliliter of solution, and l is the path length of the polarimeter tube in decimeters (these units are employed for historical, rather than rational reasons).

是在旋光仪中的旋转角的读数，C是缩胺基脲溶液的浓度，以每千分之一公升溶液中的公克数来表示，而l是旋光仪试管的通路长度，以分米表示(这些单位都是历史沿用下来的，而没有合理的原因)。

The thermodynamic calculation results indicated that the formation of calcium aluminate hydrate from aluminate solution with CaO is easier than that with Ca2, and the value of αk is great at low temperature; the temperature rise leads to the reduction of stability of calcium aluminate hydrate in the aluminate solution, and it can be decomposed at high temperature, which can both substitute for Ca2 and recover alumina in the process of Bayer.

热力学计算结果表明，氧化钙较氢氧化钙更容易使铝酸钠溶液中的铝酸根离子转化为水合铝酸钙，使铝酸钠溶液的平衡苛性比能达到很高的值；水合铝酸钙随着温度的升高，稳定性降低，因而能在拜尔法高温溶出过程中分解以代替石灰，并回收其中的氧化铝。

This equation was tested by the renaturation processes of denatured egg white lysozyme in guanidine hydrochloride and urea solutions, with the results to show that when guanidine hydrochloride and urea concentrations were separately higher than 1.25 and 3.00 mol/L or separately lower than 1.00 and 3.00 mol/L, the refolding intermediates of egg white lysozymes were more easily aggregated to aggregate state or more easily renatured to native state, respectively.

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
