加倍

This does not happen easily. As every author knows, even a single volume requires a great deal of careful organization and hard work. All the more must we appreciate the clear view and the patience and energy which Knuth must have had to plan seven volumes and to set about implementing his plan so carefully and thoroughly.

任何一名作者都明白，即使是单卷本著作也需要付出大量艰苦的工作并进行严谨的组织，我们可以想象得出高德纳教授如此全面而审慎的制定了出版七卷本的计划并令其成为现实所具备的清晰的大局观和付出的过人精力，这并非易事，我们必须加倍感谢他的工作。

Meanwhile, by either artificial chromosome doubling via colchicine treatment or spontaneous chromosome doubling via a union of unreduced gametes (2n) from T. turgidum-Ae.

同时，通过秋水仙碱对四倍体小麦-节节麦杂种进行染色体人工加倍或利用未减数配子自然加倍，我国科学家创制了一些新的人工合成小麦。

With the new herbicide-oryzalin to treat the callus with young buds of coloured Zantedeschia aethiopica in vitro, the effects of oryzalin of different concentration and time duration on doubling chromosome of coloured Z. aethiopica were studied.

用新型除草剂Oryzalin作为彩色马蹄莲体细胞染色体加倍的诱导剂，以愈伤组织芽点为处理材料，研究了不同处理浓度和处理时间的除草剂对彩色马蹄莲染色体加倍的影响。

Redoubles : A redouble is natural except the following, which are for takeout

再加倍：除了以下情形被当作逼叫来使用之外，再加倍为自然意义就是要打

Adopt the battery makes power supply, adopting the CMOS chip and liquid crystal display that the low 功 consume, taking place the machine usage LCD to flap,count to flap to concuss the machine CD4060 and double D to trigger the machine CD4013, counting a synchronous double of the machine adoption ten enter to make to count the machine CD4518, lock to save to translate the code machine is a CD4543, the whole telegram the electric circuit use CD4082, CD4011 and loudspeaker composings.

采用电池使力量供应，采用互补型金属氧化半导体薄片和液晶显示器低点消费，发生机器用法 LCD 拍打，计算拍打剧烈地震动机器 CD4060 和加倍 D 引起机器 CD4013，计算机器采用十的一个同时加倍进入制造计算机器采用十进入制造计算机器 CD4518，锁解救翻译密码机器是 CD4543，整个的电报电路使用 CD4082 、 CD4011 和喇叭筒构成。

Smearing apical point with a mixture of 0.2% colchicine plus adeps lanae and 1.5% DMSO was also effective with doubling frequency 14.0%. Dripping the apical point of plantlets with trifluralin has also been tested, and it showed effective in inducing tretraploid from double haploid, but obviously delayed plant growth.

本试验还用具有抗微管形成的除草剂氟乐灵进行黄瓜幼苗滴苗加倍试验，试验结果表明，在进行黄瓜双单倍体诱导纯合四倍体时，氟乐灵具有使染色体加倍的功能，但同时也具有延迟处理植株生长的作用。

Tetraploid induction from double haploid was also studied, and a desirable result has been obtained. Dripping the apical point of plantlets with 0.2% colchicine plus 1.5% DMSO was a suitable treatment with doubling frequency 18.2%.

其中0.2％秋水仙素+1.5％DMSO滴苗处理，效果较明显，加倍频率达18.2％。1％秋水仙素+羊毛脂膏+1.5％DMSO涂抹生长点试验，加倍率为14.0％，由于此法田间工作量小，不失为双单倍体诱导纯合四倍体较好的方法。

The paper summarized the principle of multiploid and the advantages of multiploid of medical plants application,summed up the common methods in artificial induction multiploid of medical plants and identification of chromosome doublings,brought forward a few key problems which should be paid attention in polyploid breeding of medical plants and its research prospect.

概述了多倍体的原理及药用植物多倍体的应用优势；总结了人工诱导染色体加倍的常用方法和染色体加倍的鉴定方法；并提出了药用植物多倍体在该领域中存在的问题及研究前景。

And suddenly the atmosphere grew as blue again as before; the forest grew red, and green, and yellow-colored.

于是天空显得比以前加倍的高阔，加倍的蔚蓝；树林染上最华美的红色、黄色和绿色。

And suddenly the atmosphere grew as blue again as before; the forest grew red, and green, and yellow-colored.

小姑娘说。于是天空显得比以前加倍的高阔，加倍的蔚蓝；树林染上最华美的红色、黄色和绿色。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
