Under the same environmental conditions when the meiosis of microspore mother cell develop into tetrads the female buds were dipped duly with colchicine solution, which guaranteed that chromosome doubling of megaspore in white poplar could be accomplished in a short time. So much workload was cut down, and induction efficiency of triploid white poplars was also improved.

当相同生境以及培养条件下的小孢子母细胞减数分裂达到四分体后，适时采用秋水碱溶液对雌花芽进行浸泡处理，可保证白杨大孢子染色体加倍处理能集中于一个较短的时间段内进行，从而大大减轻了工作量，同时提高三倍体诱导效率和效果。

It was thought that space induction caused the variation of size, fertility and the abnormal meiosis.

分析认为花粉的大小差异和花粉的育性与减数分裂异常有关，而这些现象都是航天诱变造成的

The detailed procedures of the method are as follows: the charging material of Ti-6Al-4V alloy is put into the crucible of an induction skull melter, heated and melted under the environment of high-purity argon and 400-700Pa pressure; pre-coated bars with the TiH2 of the weight accounting for 0.09 to 0.2 percent of the charging material are added in; when the hydrogen-contained titanium alloy in the crucible cools and the temperature drops below 300 DEG C, the charging material is vented off and cooled until the temperature equal to room temperature.

它的具体方法为：将Ti-6Al-4V合金的炉料装入感应凝壳熔炼炉的坩埚中，在压力为400～700Pa的高纯氩气环境中进行加热熔化；然后熔入含炉料质量0.09％～0.2％的TiH2的预制棒；当坩埚中含氢的钛合金逐渐冷却凝固并降温至300℃以下后，破真空，进一步冷却至室温。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
