代替

To deal with large problems, a two-piece up-date of two-side-reduced Hessian is used to replace the full Hessian matrix.

When the mesostructure is basically formed, the pH value of the reaction system is adjusted to 7-8 and then the hydrothermal crystallization is prolonged for some time to obtain heteroatom-incorporated mesoporous silica. The aim of adjusting pH value to near neutral is to change heteroatom species from the cationic to oxo form and therefore can enter the mesoframework through condensation with silanol groups in the wall.

该方法主要的特点是：操作简单（以调节体系pH值代替繁琐的后处理过程），效率高（可以得到Si/Al=5且铝物种全部处于四配位的骨架位置的Al-SBA-15），不破坏产物有序结构（产品具有高度有序的介孔结构），具有普遍性（适用于多种杂原子的掺杂如铝、钛、钒）。

That urine and hexamethylenetetramine taking the place of sodium carbonate as the precipitants could also produce 1D Co3O4 showed lights on understanding the mechanism of formation of 1D structures.

Whenever calculus is brought in, or higher algebra, you could take it as a warning that the operator was trying to substitute theory for experience, and usually also to give to speculation the deceptive guise of investment.

一旦引入了微积分或者高等代数，你可以把这看作是一个警告，这意味着使用数学者是在用理论代替经验。通常这给了投机欺骗性的伪装，变得好像是投资一样。
