There are explicit and implicit schemes in FDM . explicit scheme are easy to compute and make programmes, but it has a problem of conditional stability and the exactness is not high .

有限差分方法主要有，显式格式和隐式格式(Crank-Nicolson格式)，其中显式格式虽然计算简单，便于编程，但有稳定性限制，并且精度也比较低，不便于适用。

The students learn too little implicit cultural background knowledge some words connote in the textbooks.

In fact, the style of contemplativeness refers just to such characteristics of Du's poetry as deep thought, strong emotion, tragic sense, tender feelings, implicit comfort and nostalgia.

而要想做出这个系统的归纳，不仅要弄清杜甫本人所说的含义，还要弄清后人在以这一概念描述杜诗风格时所赋予的新的含义。

In fact,the style of contemplativeness refers just to such characteristics of Dus poetry as deep thought,strong emotion,tragic sense,tender feelings,implicit comfort and nostalgia.

沉郁顿挫的风格是指杜诗运思深刻，感情浓烈，声情悲壮，而又忠厚缠绵，含蓄蕴藉，回环往复的特点。

This point is less explicit in Van Til, but it is implicit, for example, in a passage where he quotes Arminius as denying "that a thing which, in regard to second causes, is done contingently is said to be done necessarily in regard to the divine decree."

范泰尔关於这一点的说明并不多，不过他在一段讨论中暗示了这观点。

In calculation, the discretization of continuity equation is performed in accordance with semi-implicit Scharfetter-Gummel scheme and the electric field is solved by the current conservation instead of the Poisson's equation, so it saves plenty of time for calculation.

在计算中，对于粒子的连续性方程我们采用Scharferter和Gummel提出的有限差分方法，并用电流守恒方程代替泊松方程来求解电场，从而节省了大量的计算时间。

In order to get the numerical solution, the paper devises a three hierarchic implicit scheme which eliminates the strict restriction of explicit scheme, thus, it can be used in more areas. By using the energy estimation method, the convergence and stability of the difference scheme are proved and the scheme is second order convergence for time and space.

对求解方程构造了一个三层隐式差分格式，消除了显格式的稳定性对计算步长的严格限制，使之适用范围更广，并用能量估计的方法严格证明了差分格式的收敛性与稳定性，该格式对于时间和空间均具有二阶收敛性。

Further, it is proved that the semi-implicit Euler method is convergent with order 1/2 in mean square sense for the linear test equation by virtue of properties of the conditional expectation.

在此基础上由条件期望的性质证明了半隐式Euler方法应用于线性试验方程时在均方意义下是l／2阶收敛的。

Let C be a nonempty closed convex subset of a Hilbert space H, P:H→C be a nearest point projection, and T:C→H be a nonexpansive mapping satisfying the weakly inwardness condition, and :C→C be a fixed contractive mapping. Let the implicit iterative sequences {x},{y} and the explicit iterative sequences {x},{y}.

设C为实Hilbert空间H的非空闭凸子集，P：H→C为最近点投影映射，T：C→H为非扩张映象，且T满足弱内向条件，：C→C为压缩映象。t∈(0，l)，定义了2种隐式粘性迭代序列{x}，{y}和2种显式粘性迭代序列{x}，{y}，证明了T有不动点当且仅当序列{x}，{y}，{x}，{y}有界。
