不能交换

During my break times, I would bring back to mind that beam of light which penetrated into our computer case on that special day.

我有点后悔没有交换电子邮件，也没能和她道别。不忙的时候，我会一个人怀念射进机箱的那股阳光。

Between class of service and quality of service, RSVP, 802.1Q/p, VLANs, cut-through routing, routing and Layer 3 switching, it's no wonder network managers are confused about the best method for optimizing control over a seemingly chaotic environment.

在服务种类和服务质量之间，有rsvp、802.1q/p、vlan、抄近路的路由、路由与第三层交换等，怪不得网络管理人员也搞混了，弄不懂哪一种办法能优化控制这一看来越来越乱的环境。

Experiments show that the algorithm has a good invisibility and resistance to most geometry attacks, such as rotation, small rescaling, shifting, and MPEG compression. Experiments also show that the algorithm has a good robustness against temporal synchronization attacks, such as frame insertion attack, frame drop attack, frame transposition attack.

实验表明算法具有不错的不可见性，并能很好的抵抗诸如旋转、放大、平移、压缩编码等几何攻击和帧插入、帧删除、帧交换等时域同步攻击。

However, when two monkeys were placed in separate but adjoining chambers, so that each could observe what the other was getting in return for its r**haviour became markedly different.

参考译文：然而当两只猴子被关在分开但相邻的两间屋子、让它们能互相看到对方用石块交换到什么物品时，他们的行为就明显不一样了。

If Java non-blocking I/O was adopted in the system, the One thread can process multiple connections at a time by Java non-blocking I/O APIs, which can solve the problem of the mismatch between the network speed and the speed in PC.

作者单位：（中国兵器工业第58研究所军品部，四川绵阳 621000）摘要：采用Java非阻塞I/O方式，一个线程可同时响应多个连接，能解决网络数据传输速度与PC机内数据交换速度不匹配。

YR-cohesion chromosome model will give a better answer to the questions such as exchange,centromere,holocentromere,synaptonemal complex,polytene chromosome,puff,lampbrush chromosome,chromosome banding,non-segregation of sister chromatid,pollentube pathway and biological evolution.

YR-染色体模型能自然、合理地解释所有遗传现象，如交换、着丝粒、全身着丝粒或弥散型着丝粒染色体、同源染色体联会及联会复合体的中央区、多线染色体与膨突、灯刷染色体、染色体分带、姊妹染色体由前期到中期不分开、花粉管会导入外源遗传物质、高等生命是怎样从原始生物进化而来的等等。

High performance ion exchange chromatography has been demonstrated to be capable of efficient separation of bacteria of different species with high resolution on the base of the differences in both electrostatic charge property and structure of the cell.

高效离子交换色谱已被证明能根据细菌细胞的荷电性及表面构造快速而高分辨率地分离不同种属的细菌。

The electronic structures of cluster Fe8 with D6h symmetry and Fe15 with Oh sysmmetry have been studied by MS-X method..The results show that(1 the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-directionof the electrons transferred is in accordance with the symmetric characteristics...

用MS-Xα方法研究了Fe8原子簇（具有D6h对称）和Fe15原子簇的电子结构，结果表明：（1）两种原子簇中的Fe原子磁矩及其d能带中的交换劈裂性质互不相同；（2）两类原子簇中的电荷分布不是均匀的，电荷倾向于从外围原子向内部原子上转移，并且被转移电子的自旋方向与原子簇的对称性质密切相关。
