杂交

In order to correct the locality and partiality in the classical analysis method for investment, a genetic algorithm used in short-term stock investment analysis is proposed. Significance of chromosome, adapt value parameter in the stock market is explained and an applied scheme of selection, crossbreed, and variation operator is designed.

针对传统投资分析方法的局限性和一定程度的片面性，提出将遗传算法运用于股票短期投资分析，具体解释了染色体、适应值等参数在股市分析中的实际意义，并设计了选择、杂交、变异算子的使用方案，同时改进了算法——提出"伸展算子"。

Different parent have different hereditary effects of yield and quality traits. Rational select the parent will help to crossbreed of Island Cotton and to use hybrid heterosi.

不同亲本对产量、品质性状的遗传效应不同，合理选配亲本有助于海岛棉杂交育种和杂种优势的利用。

That is because only large firms have been able to afford the supercomputers needed to mutate and crossbreed large virtual genomes—and then simulate the behaviour of their offspring—for perhaps 20m generations before the perfect design emerges.

那是因为，一直以来仅有大型企业能负担得起所必需的超级计算机，其用途是变化并杂交大型的虚拟基因组——接着模拟它们后代的行为方式——而可能要生成2000万后代才能获得完美的设计。

Among the rice grown in Taiwan that is considered of excellent quality is Taikeng 9, which represents a crossbreed of a Koshihikari cultivar with a native Taiwanese variety.

目前台湾属於良质米品种的台P九号，就是以越光米变异新品系和台湾本土品种杂交而成。

Northern crossbreed results showed that it is expressed only in human brain. This gene has a 50% amino acid sequence identity with Caenorhabdilis elegans, Anopheles gambiae sir arid Drosophila, and 94% amino acid sequence identity with Rattus norvegicus and Mus musculus.

Northern杂交结果表明：该基因只在人类大脑组织中表达，且与无脊椎动物线虫、疟蚊和果蝇的同源基因有50%的氨基酸同源性，与脊椎动物大鼠和小鼠的同源基因有50%以上的氨基酸同源性。

In this paper, the significance of crossbreeding is also discussed.

讨论了这一模型对杂交育种工作的意义。

It is probably a result of crossbreeding.

它估计是杂交繁殖的结果。

But traditional crossbreeding is a slow process.

但是传统的杂交繁育是很缓慢的过程。

Whatever you call them they are the result of either deliberate or accidental crossbreeding.

不管你叫他们是因故意或偶然杂交改良。

Unfortunately, they went extinct in the wild during the 20th century due to hunting and crossbreeding.

但是在20世纪中期，受到猎杀和杂交的影响，他们几乎绝迹。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
