交换

By simulating the switch unit, it can be seen that ATM switch unit that is designed by use of hierarchical design of top down with VHDL can perform the basic function of cell head changing, routing and queuing. If many cells race one output channel, the ATM switch can put these cells into a buffer, then queue and output them. When the broadcast cell advents, it can be delivered to all channels.

本文通过对所设计的基于VHDL描述的ATM交换单元进行仿真验证可以得出如下结论：采用自顶向下的层次化设计、由VHDL描述的ATM交换单元能够实现信头变换、选路和排队三项基本功能；当多个信元同时竞争某一出端时能够对信元进行缓冲存储和排队输出；而且当有广播信元到来时还可以对所有出端进行广播输出。

The problem is how to consider the relativistic corrections to this potential. Adopting the assummation that the quark interaction is the sum of the usual one-gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2/c2to the Cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one-gluon direct exchange at short distances.

采纳库仑势源于单胶子直接交换，而线性禁闭源于标量和矢量的混合，同时考虑在短程区域与单胶子直接交换起同样作用的同味正反夸克的湮灭，构造了静态夸克-反夸克势到v~2／c~2级次的完全相对论修正，并拟合计算了重介子偶素的能谱，讨论了相对论修正对重介子偶素能级分裂的作用。

Benes (1965) constructed an example to show that using packing routing strategy can make the number of middle crossbar required lower.

在1965年，班尼斯 Benes 举了一个例子说明，使用「优先选最忙的中继交换器」的策略，真的可以降低中继交换器的使用数目，而依然还是能让此网路不阻塞。

Crosstalk characteristic in dilated Benes switching network, principally in a special architecture of modified dilated Benes is investigated in this section.

通过本算法，选择合适光交换网络路由方式实现消除8×8光交换网络带内串扰，并把算法扩展到N×N DB结构。

In what Mr Audrines describes as a barter arrangement (in which the Cubans seem to get the rough end), Caracas will trade them for eight macaws, two tapirs, a puma and four capybaras.

在这个Audrines先生所说的交换安排中，加拉加斯会用八头金刚鹦鹉，两只貘，一头美洲豹和四只水豚来交换。

Non-conditional love seeks to embrace those that freely love in return in an exchange of energies between heart chakras; or seeks to have boundaries with those who do not freely love as perhaps they have yet to open their heart charkas enough through ascension to allow for such an exchange.

无条件之爱寻求来融合那些自由爱的人，以心脉轮间能量的交换为回报，或寻求和那些不自由爱的人划开界限，因为可能他们没有在提升中足够打开心脉轮来允许这样的交换。

Non-conditional love seeks to embrace those that freely love in return in an exchange of energies between heart chakras; or seeks to have boundaries with those who do not freely love as perhaps they have yet to open their heart charkas enough through ascension to allow for such an exchange.

无条件之爱寻求和那些自由来爱的人融合，以心脉轮间能量的交换为回报；或寻求和那些不自由爱的人设置界域，因为那些人可能并没有在提升中打开足够心脉轮来允许这样的交换。

Non-conditional love seeks to embrace those that freely love in return in an exchange of energies between heart chakr as or seeks to have boundaries with those who do not freely love as perhaps they have yet to open their heart charkas enough through ascension to allow for such an exchange .

无条件之爱寻求来融合那些自由爱的人，以心脉轮间能量的交换为回报，或寻求和那些不自由爱的人划开界限，因为可能他们没有在提升中足够打开心脉轮来允许这样的交换。

Compared with the exchange and mutation operation in genetic algorithm ,crossover operation becomes helpless when adaptive value of most individules in demes have little difference.The algorithm falls into local solution and can't be solved by exchange. Although mutation can make it shake off local convergence and jump out of local solution, denteric mutation may destroy the produced module that is constructive to form the optimal solution.

相比遗传算法中的交换和变异操作，当种群的多数个体适应值相差不大时交叉操作就显得无能为力，算法陷入局部解而不能由交换解决，突然变异能够使之摆脱局部收敛而跃出局部解，但是后期的变异可能破坏已产生的对形成最优解有建设性作用的模块。

The application of the plant materials increased soil exchangeable base cations and decreased soil exchangeable Al significantly.

添加植物物料使土壤交换性盐基阳离子含量明显增加，土壤交换性铝含量明显减少。

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%.
