发育

The snail was found to have an indirect developmental type in the early development. The fertilized eggs were oval-shaped and discoidal cleavage. Embryonic development stages were divided into cleavage, blastula, gastrulae, trochophore, and intra-membrane veliger. Larval development stages included veliger, late veliger and crawling larvae metamorphosed to juvenile.

The basal geomorphology structure of the Tidal-Basin System of the Tiaozini Sandbanks is watershed and tidal creek system. We analyses its formation, evolvement, geomorphology characters and development and discusses the main influence factors which is water, sediment and space. We divide the evolution phases which is formation phase, autumn phase and contabescence phase. In the end we confirms its main functions, which is discharging the folium water on the tidal flat of the Tidal-Basin in the end of the ebb-tide, transporting sediment to Tidal-Basin through tidal creek systems, confining the swing range of the dynamical axis of flood tide or ebb tide, balancing the dynamical status of the South and North. At the same time, we compare coastal tidal-basin and sandbanks tidal-basin on geomorphology characters, formation causes, style and so on.

条子泥潮盆—潮沟系统的基本地貌结构为分水滩脊和潮沟系统，本文分别对它们的形成与发育、地貌特点及动态变化进行了分析，并探讨了影响其发育的主要因素，即来水条件、来沙条件、空间条件，划定了其主要发育阶段，即形成期、成熟期、衰亡期；在上述分析的基础上确定了潮盆—潮沟系统的主要功能，即通过潮沟系统渲泄落潮后期滞留在其潮盆范围内的滩面薄层水、通过潮沟系向潮盆内部输入或输出泥沙、限制涨落潮动力主轴摆动范围、平衡南北两侧动力状态；同时针对岸滩潮盆—潮沟系统与沙洲潮盆—潮沟系统的地貌特征、成因类型等进行了对比分析。

The other cells of the tetrad undergo degeneration. The mature embryo sac consists of an egg apparatus, a central cell, and 3 antipodal cells. The embryo sac is a monosporic Polygonum type. The zygote develops into a mature embryo going through proembryo, globular, heart, and torpedo stages.

胚囊发育类型为单孢子蓼型胚囊； 2胚的发育经过原胚、球形胚、心形胚和鱼雷胚等阶段发育为成熟胚；胚柄在球形胚时期最发达，但胚柄短小，只由3个扁平细胞组成，之后逐渐退化。

My baby is now 5-month, and three months before the development of height and weight were normal, 61 centimeters height, weight 12 kg, since the first three months after the reduction in appetite, eating横抱milk does not like the original one can eat 120 milliliters of milk, to four months when the first can only eat 40 milliliters of milk, after more than hospital treatment, eating MAMIAI, no obvious Pikexin electuary results, a month ago, went to Beijing Children's Hospital to see a doctor, opened Xiaoerkang, athletes Xiaoshi Oral Liquid and so on, has just started to eat better when, a few days later without effect, because the spleen and stomach weakness should not lead to effective absorption of nutrition, started missing Zinc, growth and development is almost stopped, sparse hair, nearly two months of height, weight, no significant growth, but also mental state line, is consistent with the symptoms described in medical rickets disease, do not know how good the spleen and stomach as soon as possible conditioning to restore growth and development.

我家孩子现在5个月大了，三个月前身高体重发育均正常，身高61厘米，体重12斤，自从第三个月后，食量减少，吃奶不喜欢横抱，原先一次能吃120毫升牛奶，到四个月大时一次仅能吃40毫升牛奶，后到多家医院治疗，吃妈咪爱、脾可欣均未明显见效，一个月前又到北京儿童医院看医生，开了小儿康、健儿消食口服液等，刚开始吃时效果较好，几天后又无效果，因为脾胃虚弱导致不能有效吸收营养，开始缺锌、生长发育几乎停止，头发稀疏，近两个月身高、体重没有明显增长，但精神状态还行，现症状符合中医学上所说疳症，不知如何能尽早调理好脾胃，恢复生长发育。

The development of the embryo sac is Polygonum type with numberous ...

小穗发育雌雄异熟，雌蕊的发育早于雄蕊的发育。

The first pathogenetic gene identified is α-synuclein, but its phathological mechanism is unknown. In previous study, it's demonstrated that all synuclein isoforms expressed massively in early embryologic development of the central nervous system.

先前有研究指出所有的synuclein异构型在胚胎发育早期即在中枢神经系统被大量表现，显示这一类基因对中枢神经系统的发育可能是很重要的，但是研究synuclein在胚胎早期发育方面的相关研究则较少。

促进生长发育和提高智商牛初乳中所含的牛磺酸、胆碱、磷脂、脑肽等是儿童生长发育不可缺少的营养物质。具有促进智力发育的作用。

The study of the status of drift sands is mainly concentrated in the developmental model of eolian landform of each regions.

对风沙活动现状的研究，主要集中在各区主要风成地貌的发育模式方面，试图通过对各种中、小尺度的风成地貌发育模式的研究，揭示其发育过程和物理机制。

We can not find any known domains in BEX1, but we notice that the C-terminus of it is similar to p75NTR-associated cell death executer, which is also highly expressed in brain and X-link. It may be a signaling adaptor molecule involved in p75NTR-apoptosis induced by nerve growth factor.

已有文献报道，在小鼠植入前的胚胎发育过程中Bex1基因在转录水平表达量发生变化，在出生后睾丸的发育过程中表达也有差异，说明这个基因与小鼠的发育相关。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
