体节

They have segmented with two or three distinct parts, and jointed appendages on the segments.

它们被分成两个或三个明显的体部，并连接体节的附肢。

Shrimps belong to Crustacea in Arthropoda. They have heteronomous segmentation.

虾属於节肢动物门甲壳纲，身体各体节有不同的形态(异律分节，heteronomous)。

During embryonic development, many animals form a number of temporary structures along their anterior-posterior axis-somites. Cells in somites differentiate into sclerotome, which gives rise to vertebral column, dermatome, which gives rise to dermis, and myotome, which gives rise to skeletal muscle.

脊椎动物在胚胎发育的过程中沿身体前后轴形成一定数目的暂时性结构－体节，随着胚胎的继续发育每个体节分化成为生骨区、生皮区和生肌区，继而生成各种组织。

In our experiment, we found two abnormal phenotypes that one only the last three segments develop into pupa, but the other segments are still keep the larva characters; another sample has differently develop speed between abdomen and backside, which resulted in the back develop into pupa but the abdomen were still the larva characters. When we add Az in the feed of injected EcR-dsRNA samples, in the 13 live larvae we found that 6 have the abnormal proleg phenotypes.

在另一组注射EcR-dsRNA以后通过浸叶法添食不同浓度的印楝素，在10ppm处理组存活的13个个体中有6个出现特异表型，其中两个幼虫为不完全蜕皮，尾部体节无法蜕皮导致发育受阻；另外发现4个供试虫体发育至五龄时出现腹足缺失表型，其中有两个是腹足几乎全部缺失，腹足应该生长的部位只有少数几个突起，没有发育成形的腹足；一个出现左侧腹足完全缺失，右侧第二腹足缺失表型；另一个个体只缺失了左侧最后一个腹足。

Using RT-PCR analysis, RGS7 was expressed from fertilization to 96 hours post-fertilization of Zebrafish. Expression of RGS7 was found in brain、aorta ventralis、intermediate cell mass and somite by whole-mount in situ hybridization.

因此，利用RT-PCR以及全胚体原位杂合技术，结果发现在受精后0~96小时的斑马鱼胚胎中皆可侦测到RGS7的表现，其表现的位置是在斑马鱼胚胎的脑部、腹侧主动脉、中期细胞团及体节等组织部位。

Toxic symptom of embryo was body curvature,body atrophy,body deformity and pericardial tumefaction.

纹缟虾虎鱼胚胎在3种重金属影响下出现身体弯曲、萎缩和残缺，未能形成体节，心包囊肿等症状，还会出现较少见的胚体分叉、增生现象。

Undifferentiated tissue from which new cells are formed, as at the tip of a stem or root meristematic

分节的，分成体节的 meritn。功绩，价值，真相

Generally we think muscular histogenesis has many steps of biology, including foetal mesoderm merotomy; myoblast shapes in arthromera; myoblast can form muscular tissue to move to limbs; the proliferation of sarcoblast can increase cells\'quatity.

一般认为，肌组织发生是一多步骤的生物学过程，包括胚胎中胚层的分节；成肌细胞在体节形成；成肌细胞向四肢迁移形成肌组织；成肌细胞增殖以增加细胞数量。

Arthropods having the trunk composed of numerous somites each bearing one pair of legs: centipedes.

由许多体节组成躯干，且每个体节有一对腿的节肢动物；蜈蚣。

During the past three decades, several models have been proposed to explain the formation of somites, including the clock and wavefront model, the reaction-diffusion type model, the clock and induction model, the clock and trail model, and others.

近30年来，研究者们就体节的发生和分化提出了多种解释模型，这包括时钟波峰模型、反应扩散模型、时钟诱导模型、时钟痕迹模型等，这些模型从不同角度不同程度解释了动物体节发生和分化的不同现象。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
