Alternation of generations can be divided into two basic types, one for the same shape alternation of generations, the sporophyte and the gametophyte in the morphology similar size, only cytology and physiology are different, such as Ulva, etc.; another type of shape alternation of generations, that is, in the sporophyte and gametophyte morphology and size are also significant differences.
世代交替又可分为两种基本类型,一为同形世代交替,即孢子体和配子体在形态大小上类似,仅在细胞学上和生理上有所不同,如石莼等;另一类型为异形世代交替,即孢子体和配子体在形态结构和大小上也有明显差异。

NXT Generation Spray Wax – This liquid spray on wax is a companion product for Meguiar's NXT Generation of car care products built with ESP's for today's advanced polymer finishes. NXT Spray Wax builds on the results you have already achieved using NXT Tech Wax. NXT Spray Wax is an excellent maintenance product to maintain your protection, in-between regular applications of NXT Tech Wax. This is not a quick detailer and should not be used to remove dirt and dust accumulation. It is also not a replacement for a regular coating of any wax. NXT Spray Wax can be used with all Meguiar's waxes, but chemically works best with NXT Spray Wax.
次世代喷蜡-这瓶液态蜡喷剂是与ESP(工程合成聚合物,使用於目前较先进的聚合物烤漆)一起发展的美克拉次世代汽车保养产品系列中的一个产品,次世代喷蜡的效果取决於你使用次世代科技蜡已经达到的成果,次世代喷蜡是一个出色的保养产品,它可以在你每次施用次世代科技蜡的期间去维持其保护性,它并不是一种快速保养液,所以不应该被使用来移除漆面上累积的脏污和灰尘,它也不是用来取代任何一般的蜡涂层,次世代喷蜡可以与所有的美克拉蜡一起使用,但是与次世代科技蜡搭配使用是最佳的。

To disease resistance, SP3 (from H1) had stronger ability to resist leaf mold. 4.The characters obtained by space mutation were easier to be stable. The results showed that, the differences of the flowering dates of 1st inflorescence, the positions of 1st inflorescence, number of leaves between 1st and 2nd inflorescences in the colony were decreased with the development of generations. Most of these heritable characters could be stable in SP3 and a few could be stable in SP4, 2~3 generations earlier than that of traditional breeding (The characters were stable in 6 generations.).
试验结果表明,植株的第一花序开花期、植株的第一花序节位、第一至第二花序间隔叶数及产量的株间变异(变幅、标准差和变异系数),随着世代的递增而降低,大部分株系的变异性状从SP3后就稳定遗传,少数株系的变异性状从SP4后才稳定遗传,比一般常规育种的6个世代开始稳定,可提早2~3个世代,经地面定向选择能较快选出综合性状优良的目标株系。

Now Ms. Grimes does a different kind of digging. She works at Google, where she uses statistical analysis of mounds of data to come up with ways to improve its search engine.Ms. Grimes is an Internet-age statistician, one of many who are changing the image of the profession as a place for dronish number nerds. They are finding themselves increasingly in demand — and even cool.
