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。

On the one hand, The empirical model is remedied to investigate themicrowave emissivity of sea surface under wave breaking. In this model, we havediscussed the effects of spherical bubbles and droplets of whitecaps and difference intemperature between air and sea water on the emissivity of sea surface. Themodel results indicate that the effective seawater emissivity increases with DTBASincrease.

在被动遥感方面提出了一个改进的研究海浪破碎产生白冠时海水有效发射率的模式，讨论了白冠层中主要成分为球形气泡和水滴的情况，并着重分析了海-气温差对海水发射率的影响，研究表明海水发射率随着海-气温差的增大而增大。

The success was mainly due to the dilution of sea water to certain extent ( 25-50%) so that the Tradescantia inflorescences could remain alive during the time pe-riod required in the experiment.

我们发现紫露草能于海水中在实验要求的时间内成活，并通过实验证实了微核产生的原因不是海水本身，而是海水中的污染物质，污染物质含量越高，产生微核的频率也越高。
