The main idea of the finite difference method is as follows: We consider the discrete difference equation with the finite alphas as approximate substitution for the differential equation with the continuous variant and boundary conditions.

有限差分方法的基本思想是用离散的，只含有有限个未知数的差分方程去近似代替连续变量的微分方程及边界条件，并把相应的差分方程解作为微分方程的近似解。

We could attempt to get around this difficulty by initially assigning the arbitrary value to another of the unknowns rather than to Xn.

开头对另一个而不是Xn的未知数指定为任意常数，能试图避免这个困难。

He team will be put up in the notice-board.该队名单将张榜公布? We can put up ten people for the night at a pinch...

EAM 姚的负责人章明基建议，选择一个适当的时机，携叶莉出席一个公众晚会，但这个建议叶莉能否同意还是未知数。。。。

It uses a uses the MSFlexgrid to enter the augmented matrix but its limit is 253 because I use a Byte variable to define the equations number so if you want to use it for a bigger Linear System you will have to change some variable definitions

它使用一个MSFlexgrid 来输入参数矩阵，参数个数最多是253个，因为我使用一个Byte 变量来定义方程的未知数的个数。所以如果你想在更大的线性系统中使用它，你将必须修改变量的定义。

Though it is still unknown if the space-age ball with have any effect of the performance of the game, it has been endorsed by famous players such as David Beckham, Xabi Alonso and Bastian Schweinsteiger.

虽然这个太空时代的球是否会影响球赛的表现目前仍是未知数，但一些明星球员像贝克汉、阿隆索和史汪斯泰格也都表示肯定。

So I always will think of this as a matrix A, the matrix of coefficients.

然后是未知数向量，未知数向量我们经常用X表示，大写的X。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
