变态

This conservation of a regulatory network supports the homology of metamorphosis in the chordate lineage.

因此，由甲状腺素诱导的变态过程受到了甲状腺素受体的调节，这种变态过程是所有脊索动物的祖先特征，这种调节网络的保守性也支持变态在脊索动物谱系中是具有同源性的。相关论文发表在《当代生物学》上。

The larvae in the control group metamorphosed at day 20, and the metamorphosis rate increased gradually. The larvae in group 1 metamorphosed at day 30, but those in group 2 did not metamorphose throughout the experiment, which showed that the larvae did not have enough nutrition for metamorphosis.

对照组幼虫在第20天时开始变态，随后变态率逐渐升高，试验一组幼虫在第30天时开始变态，而试验二组幼虫在试验期间一直没有变态，表明该组幼虫的营养状况不足以支持其变态附着。

It may be a modified terminal bud, as in the grapevine; a modified lateral branch, as in the passion flower; a modified leaf, as in Clematis Montana; a modified leaflet, as seen in many of the pea family; or a modified inflorescence, as in Virginia creeper.

它可能源于一个变态的芽，比如葡萄藤；或源于一个变态的枝，如西番莲；也可为一个变态的叶片，如 Clematic Montana ，亦或是一个小叶，如豆科；还可能是变态的花或花序，如五叶地锦。

The mechanism of RCC''s metamorphism is expatiate on the hiberarchy of the applying theories and the designed method of the mixed ratio of the cement grout enriched RCC was put forward by studing on the correlativity of grout materials involved in the vibration-diffusion mechanism, the mixed ratio, the cement grout enriched RCC and RCC etc. The durability of antifreezing of the cement grout enriched RCC is enhanced by the improvement and optimization of grout materials.

中文摘要：通过对变态浆材在碾压混凝土中的振动扩散机理，变态浆材掺加量、变态混凝土和碾压混凝土的关联性等的研究，在应用理论基础层次上阐明碾压混凝土变态的机理，提出变态混凝土的配合比设计方法；通过对变态浆材的改性和优化研究，提高变态混凝土的抗冻耐久性。

Several basic tenrts of otolith research have been questioned recently with regard to eel metamorphosis.specifically,some researchers have suggested that otolith increment formation is not daily,and otolith material may be resorped during metamorphosis.we conducted a rearing experiment to test the hypothesis that increment formation is daily and that the otolith continues to grow during eel metamorphosis.we marked the otolith of wild-caught leptocephali and reared these fish through metamorphosis.metamorphosis was characterized by a decreasing standard length,pre-anal length,and body depth accompanied by an increase in pigmentation and a change in behavior.

最近学者关注的鳗的耳石的研究的几个最基本的问题涉及到鳗的变形。尤其是很多研究者认为耳石的日轮沉积并非是每天的，耳石的材质可能是会在变态过程中被重吸收一部分。我们做了个养殖的实验来测试鳗鲡耳石的形成的每天一轮而且在鳗鲡的变态发育阶段耳石是在继续生长的。我们标记了野外捕捞的蠕鳗幼体，养过变态期。变态期是通过标准长度，肛前长和体高的减少和色素的减少以及行为的变化来定义的。

A cDNA segment was isolated from M. meretrix larvae. The results of caspase in situ detection in larval developmental stages revealed that there were activated caspase from L1 to L3, indicating caspase is involved in the whole developmental process. The main apoptosis area was found in velum at L3 before metamorphosis, indicating the degradation of velum might be the process of apoptosis. The larvae before metamorphosis were treated by caspase specific inhibitor to analyze the role of caspase in this process. The results indicated that caspase have function metamorphosis.

根据caspase在不同物种中的保守区域设计简并引物，在文蛤幼虫中扩增到cDNA序列片段；检测有活性的caspase在文蛤幼虫各发育时期的分布部位，发现其在L1至L3期幼虫中都有分布，说明整个幼虫形态变化过程中都有caspase的参与；细胞凋亡检测结果显示，幼虫主要发生细胞凋亡的部位在L3期幼虫的面盘，即变态过程中要退化的器官，说明细胞凋亡可能是文蛤幼虫变态过程中面盘退化的主要机制；用caspase特异性抑制剂处理变态前幼虫，发现幼虫变态率下降，初步验证了caspase在文蛤幼虫变态过程中的作用。

Solution: Verify that your computer system, the normal checks in the parallel port interface on the dog, the normal will dog-drawn off on another correctly, run the fly-over, normal, explains encryption properly.

处置办法：查抄计算机编制，变态查抄插在并口上的加密狗接口，变态不兵加密狗拔下插在另一台变态的计算机上，运行飞腾，变态，表明加密变态。

As the raise of ammonia-N concentration, survival rate and daily growth of unexuviated larvae decreased gradually, while the metamorphosis rate and daily growth of exuviated larvae increased gradually firstly and then decreased. As the raise of sulfureted hydrogen concentration, all the parameters measured decreased gradually.

在本试验浓度范围内，随着氨氮浓度的升高，三疣梭子蟹各期幼体存活率和未变态个体的日生长率都逐渐降低，变态率和变态个体的日生长率则先逐渐升高，达到一个峰值后又逐渐降低；随着硫化氢浓度的升高，三疣梭子蟹各期幼体存活率和日生长率A均呈现逐渐降低趋势，变态率和日生长率B也逐渐减小。

Based on the distorted model experiment of long tunnel,this paper mainly introduced the distorted design scheme about surge tank model,and has founded the relations of distorted model ratios.
