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。

Results showed that 1 soil structure in the rhizosphere was very high; water-holding capacity and organism count in the soil increased with altitude and duration of bamboo growth. However, soil etiolation and soil acidification was obvious. 2 Soil acidity was adjusted with lime; best applications were 10.625 thm^(-2) on the valley bottom, 14.811 thm^(-2) for the middle slope, and 12.558 thm^(-2) on the valley top.

结果显示：毛竹林根系活动层(60 cm)土壤结构较好，土壤水源涵养功能的大小和土壤的有机质质量分数随毛竹林成林时间和海拔高度的增加而增加；但土壤黄化、酸化特征较明显，土壤酸性调节主要以施用石灰为主，其中谷底毛竹林改造需石灰量为10.625 thm^(-2)，坡面的里白毛竹林为14.811 thm^(-2)，岗地毛竹林需石灰量为12.558 thm^(-2)；在氮磷钾3种元素中，氮素供应总体上良好，但要获得高产，氮肥的补充也是必需的。

Ian Findlay, from the Australian Genome Research Facility at the University of Queensland, said current DNA testing required 200 to 500 cells to gain a similar level of accuracy.

Ian Findlay ，来自在昆士兰省的大学的澳洲基因组研究设备，说现在的 DNA 测试必需的 200-500个细胞得到相似程度的准确性。

I think we already have the biological capabilities necessary to fix the problems of this planet if they're fixable at all, but we currently lack the awareness, discipline, and courage as a species to step up and take personal responsibility for doing what is right.

我觉得我们已经拥有了解决这个星球的问题所必需的生理能力，如果这些能力是稳定的话；但我们现在缺乏的是作为一个物种，为了做正确的事而去增加和担负个人责任的觉醒、自律和勇气。

Studies using FRAP in living cyanobacteria cells have shown thatphycobilisomes diffuse rapidly on thylakoid membranes, and this diffusion is requiredfor state transitions in cyanobacteria.

在蓝藻活体内利用FRAP技术的研究已经表明藻胆体可以在类囊体膜上快速的自由扩散，且该动态扩散对蓝藻的状态转换是必需的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
