闭合系统

Power optimization of amplify-and-forward relay aided OFDM communication system is discussed in this paper.

讨论了AF型中继辅助OFDM通信系统中的功率优化方案，并针对最优的功率优化方案很难得到闭合解的问题，提出了一种迭代的功率优化算法。

The method for measuring resistance parameter of earth body of sediments on surface in deep sea includes steps: in sampling procedure in seabed, closing speed of the perching knife keeps sampling at uniform speed 2cm/s; using current process system of static probing data can analyze resistance data so as to obtain parameters including intensity, compressibility, compaction degree, and thickness state of sediments, and bearing capacity etc.

深海表层沉积物的土体阻力参数的测量方法是在海底取样过程中，该铲刀闭合速度保持2cm/s的匀速取样，用现有的静力触探数据处理系统即可对采集的阻力数据并进行分析，得出沉积物的强度、压缩性、密实度、稠度状态和承载力等参数。

现代输入系统，高级函数闭合，例外与延拓（ exceptions and continuations，支持不同语言特性的运行时。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
