胚胎

The outside gill disappeared, the gill arches developed to from the branchia, later the branchia appeared primary protuberance, along with developing, it appeared the secondary protuberance and the third protuberance, until the 36 stage, the stage is the inside gill developing at the peak, later it came into the period of the metamorphosis, the inside gill degenerated, the third protuberance began shrank, next the secondary protuberance and the primary protuberance shrank, finally the gill arches shrank and disappeared, the metamorphosis completed.

内鳃的发育是首先由鳃弓上的突起形成鳃叶，其次鳃叶上出现初级突起，随着进一步发育出现次级突起和三级突起，直到内鳃发育最高峰(胚胎发育的36期)。随后进入变态期，内鳃开始退化，首先是三级突起开始萎缩，其次是次级突起和初级突起，最后是鳃弓，直至鳃弓完全消失，变态完成。

Congenital Preauricular Fistula (MIM 128700) is a common auricular abnormality, the incidence of which is around 1%. The formation of CPF is closely associated with embryological development of the auricle, which is developed from the first and second branchial arches.

先天性耳前瘘管（MIM 128700）是耳鼻咽喉科常见的遗传性疾病，其患病率接近1％，一般认为是胚胎期形成耳廓的第一、第二腮弓的六个小丘样结节融合不良或第一腮沟封闭不全所致。

Because HSG is associated with sinus tract, the embryologic origin of HSG in the lower neck may be from the branchial apparatus.

因为下颈部异位性唾液腺常伴随管窦腔，所以其胚胎的来源可能是鳃弓器。

In my silver high-heel shoes,I go to take part in a belated dinner,I go through a tall wood in a rush,On the trees there are fantastic tropical fruits and clocks streamed with egg white,The sweet fragrance of those fruits seduces me,I pick off a beautiful dragon fruit,But see many white worms lying in it when cutting it,I scream and throw it on the ground,Those worms creep to me and begin to grow,I creep onto the tree,They also creep towards the tree wiggling their bodies,I remove my cumbrous high-heel shoes and voile skirt creeping towards a high place,like an agile cheetah,But strangely my small bag oppressively cumbers me,It turns out that the bag is full of pumpkins, monkey dolls with large mouths, crystal bottles and silver coins,I give all of these a vicious discard towards the ground from the tree,But those worms open their big mouths and swallow all of them greedily,Becoming more obese and uglier,I desperately creep upwards,Suddenly the moon is not so far from me,I jump on it with ease,Suddenly finding that the moon is a porous spongy body with the fragrance of the oven-fresh French stick bread,It takes me to flow away from that tree full of worms,I want to light a cigarette but ignite the sponge on the moon,So I descend from the height,Falling down to a huge birds' nest,In an instant my whole body is wrapped by a slick and white egg shell,I find myself becoming a new embryo,Crouching in the warm and ropy liquid,The world presents a color of delicate light yellow,In a vacuum-like silence,I hear my contented voice,"What a perfect world"

我穿着银色的高跟鞋，去参加一场迟到的晚餐，我匆忙地穿过一片高大的树林，树上挂满了奇妙的热带水果和流淌着蛋清的时钟，那些水果甜美的芳香诱惑了我，我摘下一颗漂亮的火龙果，切开来却看见里面躺满了白色的蠕虫，我尖叫着将它们丢在地上，那些蠕虫向我爬来并且开始生长，我爬到树上，蠕虫们也扭动身体朝树上爬来，我脱下了牵绊着我的高跟鞋和纱裙，象只敏捷的猎豹朝高处爬去，只是我的小包奇怪而沉重地拖累了我，原来包里装满了南瓜、大嘴猴玩偶、水晶杯子和银币，我将所有这些朝树下狠狠丢去，那些蠕虫却张开大嘴贪婪地将所有这些吞食下去，并因此变得更加肥大和丑陋，我拼命努力地向上爬，突然月亮就在我不远处了，我轻而易举地跳了上去，恍然发现月亮竟是一个带着刚出炉法棍香味的多孔海绵体，它带我慢慢飘离了蠕虫的树林，我想要点燃一支香烟却不小心引燃了月亮上的海棉，于是我从高处坠落啊坠落，落入一个巨大的鸟巢，顷刻间全身被光滑洁白的蛋壳所包住，我发现自己成为了一个暂新的胚胎，蜷缩在温暖粘稠的液体中，世界呈现出微妙的淡黄色，在真空般的静寂中，我听见自己满足的声音："多完美的世界啊！"

For the enlightenment of those who are not so intimately acquainted with the minutiae of the municipal abattoir as this morbidminded esthete and embryo philosopher who for all his overweening bumptiousness in things scientific can scarcely distinguish an acid from an alkali prides himself on being , it should perhaps be stated that staggering bob in the vile parlance of our lower class licensed victuallers signifies the cookable and eatable flesh of a calf newly dropped from its mother

这位有着病态精神的审美学兼胚胎哲学家，尽管连酸与碱都分不清，在科学知识上却摆出一副傲慢自负的架子。为了启发那些对市立屠宰场的细节没他那么熟悉的人们，也许应该在此说明一下：我们那些拥有卖酒执照的低级饮食店的俚语小牛崽肉，指的就是打着趔趄的牛崽子280那可供烹调食用的肉。

Objective To investigate the possibility of commitment differentiation of embryonic stem cells induced by the medium of cultured retinal neurons of SD rats.

目的 探讨视网膜神经细胞培养的上清液对胚胎干细胞(embryonic stem cells，ES)体外分化的诱导作用。

Objective To study the effect of cadmium on the structure and function of mitochondria in HEK 293 cell.

目的 探讨线粒体在镉诱导人胚胎肾细胞(HEK 293)凋亡中的作用。

Methods POB, COB and MSC were isolated and cultured respectively in vitro from the periosteum, calvarium and bone marrow of 5-month embryos aborting spontaneously. The 6th-generation osteoblasts were studied comparatively. The morphological features of POB, COB and MSC were observed under microscope and transmission electron microscope.

从人5个月龄胚胎骨膜、颅骨和骨髓组织中分离培养出骨膜成骨细胞（periosteal osteoblast， POB）、颅骨成骨细胞（cranial osteoblast， COB）和骨髓基质干细胞（marrow stromal cell， MSC），用第6代细胞进行比较研究。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
