But these were not the two Cats which I brought on Shore at first, for they were both of them dead, and had been interr'd near my Habitation by my own Hand; but one of them having multiply'd by I know not what Kind of Creature, these were two which I had preserv'd tame, whereas the rest run wild in the Woods, and became indeed troublesom to me at last; for they would often come into my House, and plunder me too, till at last I was obliged to shoot them, and did kill a great many; at length they left me with this Attendance, and in this plentiful Manner I lived; neither could I be said to want any thing but Society, and of that in some time after this, I was like to have too much.
这两只猫已不是我最初从破船上带下来的了,那两只早就死了,我亲自把它们葬在我的住所附近。不过其中一只不知同什么动物交配,生下了许多小猫。这两只就是我从那些小猫中留下来驯养起来的,其余的都跑到树林里成了野猫。那些野猫后来给我添了不少麻烦,因为它们经常跑到我家里来劫掠我的东西。最后我不得不开枪杀了它们一大批,终于把它们赶走了。所以,我现在有那么多仆人侍候我,生活也过得很富裕,唯一缺乏的就是没有人可以交往而已,其它什么都不缺。但不久之后,我就有人交往了,后来甚至感到交往的人太多了。

Instead they were concerned about the putative effects of rural "degeneration" on the Nation and its food supply, as seen most glaringly in notorious stories about inbred, mentally defective families such as the Jukes and the Kallikaks.9 In order to counteract what they thought was the growing insularity, narrowness, and anarchy of rural life, they spent much of their time contemplating ways to rehabilitate institutions such as the country school, country church, and local county government so that they would more closely resemble urban models.
与上述研究不同,他们关注的是假设的国家乡村"退化"的结果和食物供应问题,如臭名昭著的Jukes和Kallikaks这样的近亲交配、心理缺陷的家庭,这是个典型案例。[注9]为了对付他们称之为不断膨胀的狭隘、小气和混乱的乡村生活,他们花了大量时间专注于重整体系,如乡村学校、乡村教堂和地方乡村政府,他们打算为乡村建立一个类城市模式。

The fact that the pink plants were predominant among the population of RP1 cross progeny hints that the pink had the strong descendiblity, Whereas another fact that the plants with the color of another parent were predominant among the population of R01 cross progeny indicates that the nacarat/saffron plant had the low descendiblity. The above results suggest that it is better to choose the pink plants with the target color flower of breeding as a parents when arranging the cross combination. Many novel flowers with singular value of view and admire can be bred by the different cross combination since the wide segregation chromatogram is not confined to the parents'.
以RPl及R01作母本或父本,分别与不同花色杂交,F1代发生了明显的花色分离,RP1的杂交后代均以粉色占优势,表明粉色的遗传力较强,R01的杂交后代均以其它亲本占优势,表明桔黄/桔红的遗传力较弱,因此在选配组合时,最好选择具有育种目标的粉色个体作为亲本;另外由于分离谱较广,且分离的色谱范围并不完全限于双亲之间,可根据不同的杂交配组,培育出具极高观赏价值的稀有花色。

The spermatozoa are embeded in a extracellalar matrix composed of high dense fibrils matrix and flocculent and concentric vesicles similar to that in the primary spermatophore layer, but the later lack of spermotozoa. The flocculent and concentric vesicles are often seen to release their contents around the main body of spermatozoa. The spermatozoa may absorb the contents to form vesicular zone and membrane zone in sperm nucleu. The secondary spermatophore layer is distinctly subdivided into inner region and outer region. The loose outer region consists of canaliculated reticulum and large flocculent vesicles.
输精管内的精荚为管状,由精子群、精荚基质及初级精荚壁和次级精荚壁组成,初级精荚壁与精荚基质是相连续的,它们之间无明显界限,两者均由电子密度较高的纤丝状基质和絮状泡和同心圆泡组成,但后者不含精子,后者中的絮状泡和同心圆泡常在精子主体部周围释放内含物,可能与形成精子细胞核中的泡状带和膜状带有关,在交配后的雌虾,其头胸部腹面上粘着的精荚中,其基质内已不见絮状和同心圆泡,仅见稀疏的纤丝。
