世代

Using the thin slice observation under the polarized microscopy, we have found that there are two existential ways for albite minerals in emerald: one is the first generation of albite which is earlier than jadeite or grows together with jadeite minerals; the other is albite of vein type which is formed by the hydrothermal fluid effect.

利用偏光显微镜下的薄片观察，发现翡翠中的钠长石矿物有两种存在方式：一种是第一个世代钠长石，其形成的时间早于硬玉或同第一世代的硬玉矿物一起生成，另一种为后期热液作用形成的脉状的钠长石。

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。

In plants that undergo ALTERNATION OF GENERATIONS, spores are produced by meiosis by the sporophyte generation, so are usually haploid; they germinate to produce the haploid gametophyte generation.

在具有世代交替的植物体中，由孢子体世代进行减数分裂产生孢子，因此多为单倍体。它们将发育为单倍体的配子体世代。

In organisms showing ALTERNATION OF GENERATIONS, the gametes may be produced by mitosis in the haploid generation, or by meiosis in the diploid generation and give rise directly to gametes or gamete-producing cells.

在表现出明显世代交替的生物体中，配子可能是由单倍体世代发生有丝分裂产生，亦可由二倍体世代减数分裂直接产生配子体或配子母细胞。

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。

The giant jellyfish exhibit two types of reproduction, one is asexual reproduction, including fertilized eggs, planula, scyphistoma, podocyst, strobila and ephyra; the other is sexual reproduction, including medusa or jellyfish, typically solitary, pelagic.

大型水母的生活史中有明显的世代交替现象，受精卵，浮浪幼虫，螅状体，足囊，横裂体到碟状体的幼体发育阶段属无性世代，幼蜇发育到成蜇阶段属有性世代。

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。

Tabaci was the shortest (19.3 d) on hairy gourd and the longest (29.0 d) on bitter cucumber, the survival rate from egg to adult was the highest (92.85%) on cucumber and the lowest (53.08%) on bitter cucumber, the laid eggs were the most (187.4 eggs per female) on cucumber and the least (30.0 eggs per female) on bitter cucumber, and the longevity was the longest (25.2 d) on cucumber and the shortest (10.9 d) on bitter cucumber. The intrinsic rate of increase r(subscript mon cucumber, hairy gourd, bitter cucumber, and sponge gourd was 0.1453, 0.1429, 0.0616, and 0.1055, respectively.

结果表明，B型烟粉虱在节瓜上的世代发育历期最短，为19.3d，在苦瓜上的世代发育历期最长，为29.0d；世代存活率在黄瓜上最高，为92.85%，在苦瓜上最低，为53.08%；平均单雌产卵量在黄瓜上最多，为187.4粒，苦瓜上最少，为30.0粒；雌成虫寿命以在黄瓜上最长，为25.2d，在苦瓜上最短，为10.9d.B型烟粉虱在黄瓜、节瓜、苦瓜和丝瓜上的内禀增长率r(下标 m分别为0.1453、0.1429、0.0616和0.1055。

The Yang Wei and Chao Yung were virtually unarmored. They were designed to fight a previous generation of warships. Their main guns and top speed were superior to the previous generation but technology had overtaken them. Against up-to-date Japanese cruisers like the Yoshino - they were doomed.

扬威与超勇二舰几乎是毫无防护能力，她们基本上是前一个世代的军舰，其主炮口径与航速对上那个世代的军舰具有优势，在那个世代的军舰里比较先进；然而面对更先进的日本巡洋舰时，扬威超勇的命运就已经注定了。

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.

一般人对网路世代的印象大多是成天与电脑为伍、足不出户的阿宅，而Grimes女士正是属於网路世代的统计学家，但是她和其他同属网路世代的优秀同伴们一样，致力扭转大众对网路世代的刻板印象，而大家也发现他们的能力不仅被这个社会密切的需要，而且也越来越抢手。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
