It is still needed to do some work to determine the deformation parameter β2 for light odd-odd nucleus, like 6Li and to calculate all reaction channels by means of CDCC code simultaneously. It is important to measure the exclusive angular distributions of breakup fragments.In theory, the coupling channel equations have been deduced from one-dimensional to multi-dimensional barrier tunneling. The couplings between the entrance channel and the other channels have appreciable effects on sub-barrier fusion cross section. Instead of single fusion barrier,these couplings lead to a distribution of fusion barrier Dfus.

描述了已有理论，从简单的一维势垒穿透模型出发，引入多维势垒穿透和耦合道模型，证明入射道相对运动与碰撞核各种自由度的耦合导致熔合势垒的劈裂，较低的势垒有利于垒下熔合截面增强；给出了从熔合激发函数抽取势垒分布及从背角准弹激发函数抽取势垒分布的理论依据，以及它们的优缺点。

The quasi-elastic barrier distribution D〓 extends to low energy region and enhances the fusion cross section at the sub-barrier energies. It is still needed to do some work to determine the deformation parameter β〓 for light odd-odd nucleus, like 〓Li and to calculate all reaction channels by means of CDCC code simultaneously. It is important to measure the exclusive angular distributions of breakup fragments.

得到参数化的和能量相依的相互作用势公式；发现弱束缚核〓Li+〓Pb阈异常与〓Li的形变参数β〓相关，垒下存在强的吸收势；给出破裂对熔合截面的影响在垒上压底垒下增强；熔合势垒分布向低能端展宽，有利于垒下熔合截面增强等结果；对如何确定轻的奇-奇核的形变参量β〓提出了疑问；需解决如何用从弹散角分布抽取的光学势参数，进行CDCC程序全反应道统一描写；迫切需要破裂碎片关联测量的实验数据。

Furthermore, this research shows that in angularly multiplexed recording the interpage cross-talk could be minimized by properly angled reference beams.

本论文的研究工作最终表明，在大规模全息存储时，要在存储容量、衍射效率和再现图象质量诸要素间取得最优的均衡。

The cross ratio he called anharmonic ratio.

他把交比叫作非调和比。

Swedish bearing firm is the parent company of Wo Erwo company, this founds the old name company of nearly hundred years does not have anility not only, develop the manufacturer of the biggest the bearing that cross a state on the world step by step instead, its crop takes the whole world 20% of congener product total output, follower makes an enterprise amount to many 100!

瑞典轴承公司是沃尔沃公司的母公司，这家创立近百年的老字号企业不仅没有老态龙钟，反而一步步发展成世界上最大的跨国轴承制造商，其产量占全球同类产品总产量的20%，属下制造企业多达100多家！

It seemed overstrung to cross the ankle-deep stream with hip-reached boots, therefore we just went into the water and waded into the middle of the stream.

我们穿着长及臀部的水靴，对于齐踝深的小溪来说似乎有点虚张声势，于是我们走到水里，淌进了小溪中央。

At the end, an implementation of ANSI C cross-compiler for embedded processor LS-RISC is explained in detail.

最后给出了针对一个嵌入式32位定点处理机LS-RISC的交叉编译系统的具体实现。

Not until the late 18th century did the British explorer James Cook cross the Antarctic circle , but he never saw land.

直到 l 8世纪末，英国探险家詹姆斯·库克才穿越了南极圈，但他从未发现任何陆地。

The British explorer James Cook didn't cross the Antarctic Circle until the late 18th century, but he never saw land.

直到18世纪末，英国探险家詹姆斯库克才穿越了南极圈，但他却从未发现任何陆地。

Finding only icebergs after he was the first to cross the Antarctic Circle, he wrote ruefully that if anyone ventured further and found a "land doomed by nature...to lie for ever buried under everlasting ice and snow":""I shall not envy him the honor of discovery, but I will be bold to say that the world will not be benefited by it.

Cook是第一个穿越南极圈的探险家，发现那里只有冰山，他后悔地写道：如果有探险家比我走得更远、探得更多，找到一个"被埋在永恒的冰雪下的绿地"。"我不会嫉妒他的发现给他带来的荣誉，但是我敢说：世界不会因此得到任何好处。"但事实可能会比他想的更糟。版主点评：人类自己做的孽，自己还
