四倍的

He set up a fine example to all of us.

他的蛋糕是我的四倍大。

Methylation variations of artificial F4 and F10 generations of Raphanus sativus×Brassica alboglabra allopolyploid were examined with MSAP. The results showed that the methylation levels of F4, F10 were 30.61% and 33.10%, respectively.

以人工合成的萝卜－芥蓝异源四倍体的F4和F10世代为材料，用MSAP法检测2种材料DNA甲基化变异情况，以期为远缘杂交后不同世代间基因组DNA甲基化遗传和变异规律提供实验依据。

An artificial amphiploid RSP (2n=42, AABBDD) obtained by tetraploid landrace Ailanmai (Triticum turgidum L, 2n=28, AABB) and Aegilops tauschii (DD, 2n=14) expressed high tolerance to sprouting which derived from Aegilops tuuschii.

"RSP"是利用长休眠节节麦与四倍体小麦杂交并通过染色体加倍，人工合成的优良的抗穗发芽小麦新材料。

The meiosis observation demonstrated the genomes of our autotetraploid materials were all 2n = 48, the same as those in mitosis observation.

所有四倍体材料的染色体组成均为2n = 48，这与有丝分裂的结果一致。

To establish a new technique for in vitro rapid propagation and conservation of germplasm of autotetraploid plant of Plalycodon grandiflorum, basal MS medium supplemented with different hormones was filtrated and optimized by using uniform design and orthogonal design.

为了建立优良同源四倍体桔梗的快速繁殖和离体保存技术，采用均匀设计和正交设计以添加不同激素的MS培养基为基本培养基进行筛选和优化。

Asia is four tomes as large as Europe.

亚洲有欧洲的四倍大。

That's nearly four times our sun's surface temperature.

差不多是我们太阳表面温度的四倍。

Effects of different concentrations of exogenous SOD on antioxidant enzyme activities and sugar contents in leaf and fruit were studied, taking tetraploid plant in Vitis vinifera cv 'Muscat humburg' as materials and water treatment as the CK.

以四倍体玫瑰香葡萄为试材，以喷清水为对照，探讨了不同浓度外源SOD对叶片、果实抗氧化酶活性和含糖量的影响。

And four times the size of the Roman Empire.

是罗马帝国的四倍

Or will the wing, which has been improved from a NACA 23012 profile by adding the "STOL" nose cuff to improve its original abrupt stall characteristics, stand up to the new torsional loads due to a four-fold increase in the twisting moment coefficient (cm from -.008 to -18)?

或将机翼，其中已有所改善，从naca 23012简介加入& stol &鼻子袖套，以改善其原有突然失速特性，站起来，向新的扭转载荷，由于四倍增加在扭力矩系数（厘米从-0 08至- 18）？

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
