In this paper, we studied M. meretrix ferritin, cathepsin B and caspase genes, which are involved in clam larval shell formation, nutrition, metabolism and apoptosis, respectively. We have cloned the three genes, investigated the temporal and spatial expression profile both at gene and protein level in trochophore (L1), D-veliger (L2), pediveliger (L3) and postlarvae (L4). The potential roles of these proteins were analyzed with specific inhibitors during larval development. Firstly, embryos were found developed into trochophore-like larvae with no shell if cultured at gastrula stage in artificial seawater without iron. Shell-like structures were formed only in the presence of iron. The larvae which had been transferred at L1 stage into ASW developed normal shell. This indicated that iron and iron associated protein are important for larval shell formation. The EST sequence which is homologous with ferritin, which is a principal iron metabolic protein, was selected from the M. meretrix cDNA library. The full-length of ferritin subunit cDNA was cloned by RACE. The results of real-time PCR revealed that the MmeFer mRNA expression changed before and after the larval shell formation.

本论文以文蛤幼虫为研究对象，分别对文蛤幼虫发育过程中贝壳形成相关的铁蛋白、营养及变态相关的组织蛋白酶B及变态过程中细胞凋亡相关的caspase三个基因进行了克隆，分析了基因及编码蛋白在担轮幼虫期(L1)、D形幼虫期(L2)、壳顶幼虫期(L3)和稚贝期(L4)的时空表达特征，解析了其可能的功能，并研究了相应酶类的特异性抑制剂作用对幼虫发育过程的影响，进行了目标蛋白的功能验证，详述如下：研究结果显示，在文蛤胚胎发育到原肠胚时放入不含铁离子的人工海水中培养，发育成无壳的畸形，随着人工海水中铁离子添加浓度的升高，幼虫长出壳状组织接近正常状态；而发育到L1期幼虫放入不含铁离子的人工海水中培养却可以发育出正常的壳，推测铁和铁代谢相关蛋白在幼虫贝壳初始形成有重要的作用。

Based on the iso/iec 18000-6c standard, the analog circuit of the ultra high frequency passive transponder ic is designed, according to the design requirements of analog circuit.

基于iso/iec 18000-6c标准，以设计出符合标准的标签芯片为设计目标，超高频无源电子标签芯片模拟电路被提出。

It was part of a project for Engineers Without Borders-USA, a group unaffiliated with Doctors Without Borders, but with similar humanitarian goals.

这是美国采行的一个计划的一部分，这个团体与无正式关系，但是却有类似的人道救援目标。

His chief preoccupation seems to be to avoid shaking the conservative French consensus, and even that unambitious objective has been missed.

即使这样，还是有些无奢望的目标没有实现。

For example, a risen knows that unarmored or lightly armored targets are prime candidates for power attacks, but does not often use the Power Attack feat against heavily armored foes.

比如Risen会优先使用猛力攻击对付轻装甲或者无装甲的目标，而很少用它来对付重装甲单位。

Specific applications include de novo sequencing and re-sequencing of genomes, metagenomics, RNA analysis, and targeted sequencing of DNA regions of interest. The hallmarks of 454 Sequencing? are its simple, unbiased sample preparation and long, highly accurate sequence reads, including paired reads.

具体的应用包括基因组的从头测序和重测序、宏基因组学、RNA分析和DNA目标区域的定向测序。454测序系统的特点是样品制备简单且无偏向性，读长超长且准确度高。454测序系统的技术已经催生了各个研究领域的几百项经同行评议的研究文章，例如癌症和传染病研究、药物筛选、海洋生物学、人类学、古生物学等各方面研究。

The algorithm handles the objective function and constraints separately, and adopts both directional and random search mechanism. It can avoid falling into local optimal point, which may appear in previous bionics random algorithms due to uncertainness of some parameters and/or without guiding search direction.

该算法将目标函数与约束条件分开处理，采用兼具方向性和随机性的搜索机制，避免了已有仿生类算法由于一些参数难以确定和无引导性的搜索方向而陷入局部最优的问题。

And passing out of the consciousness of no special object he fell into a state between consciousness and unconsciousness.

从没有特别目标的意识状态出来以后他进入了在意识和无意识之间的状态。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
