查询词典 F

Nf will repeat exactly after a time T = 1/f. The harmonic series is special because any combination of its vibrations produces a periodic or repeated vibration at the fundamental frequency f.

系列的谐音ㄈ长特别是因为在任何的组合下，其本身的震动产生了一个和基础频率f周期性且或重复性的震动。

Also, in this method, anhydrous hydrogen fluoride, from which moisture was removed by treating with F.sub.2 gas, is used in the steps and, and the step further comprises contacting the reaction system of the step with F.sub.2 gas.

同时，在此方法中的步骤和步骤还使用了经过氟气（F.sub.2 gas）除湿的无水氟化氢，而且步骤中还包括了其反应系统与氟气的接触。

The advantages of this method are:① the range of the exponent i of the undefined functions f from-N to N;② the indeterminate specific form of function so that we can get more new exact solutions.

点在于：①待定函数f的指数i的范围从N扩大到－N；②可以不必给出函数f的具体表达式求解方程，这样便于寻找更多的解。本文就是利用了这一特点，选择合适的参数，得到一些mBBM方程新的精确解。

Multimission avionics system is one of the important difference between the F-15 and other fighter aircraft. The system is found of head-up display, advanced APG-63 or APG-70 radar, inertial navigation system, flight instruments, ultrahigh frequency communicati**, tactical navigation system and instrument landing system.

能执行多种任务的电子系统也是F-15和其他战斗机的一个重要区别。F-15的电子系统由平视显示仪、APG-63(下图，或APG-70)火控雷达、惯性导航系统、飞行控制系统、高频无线电通信设备、战术导航系统、自动着陆系统组成。

Numerical Integration Single variable f - Calculates the definite integral of a single variable function f(x using numerical methods: The Trapezoidal, the Midpoint and the Simpson's method.

计算一个单精度变量的整数部分的函数f 使用的数学方法：梯形法、中间点中和辛普森方法。

Let f be a continuous function on the interval［a,b］, then it can reach its maximum and minimum on［a,b］.

设f是区间［a，b］上的连续函数，则f在［a，b］上达到它的最大值和最小值。

Take F=0 which governs the matter as an example, it is Newton's first law of movement, i.e. law of inertia. In the field of invisible spirit, in fact, this is the so-called "attachment to form" in the Diamond Sutra.

以掌握有形物质的理 F=0为例， F=0在有形物质是牛顿第一运动定律，也就是惯性定律，在无形精神事实上就是金刚经的「著相」。

A linear map f: M→M is said to preserve idempotence if fP(subscript nP.

若线性映射f： M→M满足fP(下标 nP，则称f是保幂等的线性映射。
