贝壳学

The nacre of molluscan shell, which is composed of inorganic aragonite tablets and a few percent of organic polymers filling between the tablets, is a wonderful natural composite material.

软体动物的贝壳珍珠质是由文石板片(CaCO_3晶体)以及少量填充在板片之间的有机质组成的一种天然的复合材料，具有复杂的形貌以及良好的力学性能、光学性能，其文石板片与有机基质交替叠层排列的微结构以及文石晶体的结晶学取向是珍珠层具有优异的力学性能的重要原因之一。

The nacre of molluscan shell, which is composed of inorganic aragonite tablets and a few percent of organic polymers filling between the tablets, is a wonderful natural composite material. It shows complex forms, and fascinating mechanical and optical properties.

An international group of authors, representing a dozen countries, draw on diverse aspects of both fossil and living bivalves, including their form, functional morphology, morphogenesis, taphonomy, shell microstructure, cladistic relationships, biostratigraphic distributions, and molecular sequences.

一个作家的国际集团，代表十多个国家，借鉴和生活都双壳类化石，包括其形式，功能形态，形态，埋藏学，贝壳微结构，分支系统学的关系，地层分布的不同方面，分子序列。

Hainan university enthralled me with its beautiful scenery and friendly environment. i have run out of steam after spending three years obsessed in aquaculture, i.e. one year for learning professional knowledge , one year for collecting oyster shells around the island and conducting awful dna experiments for another three months. time had been wasted in a nonsense way.

2004年毕业于广西大学新闻系新闻学专业，觉得&新闻无学&，决定弃文从理，于是来到了风景环境俱佳的海南大学，读了三年的水产专业，实际上是花了一年学水产专业课，大半年时间环岛收集牡蛎的贝壳，以及三个月让人头疼的化学实验。

I stacked blocks, made squadrons of paper airplanes, lined up toy soldiers, watched the "Three Stooges," planted corn kernels in paper cups, read comic books, tended my coin and stamp collections, counted baseball cards, painted shells I'd collected at the Jersey shore, picked at my guitar, wrestled with my brother, allowed my pet turtle to walk up my arm, teased the cat with string, brushed my hair in a funny way, made hand puppets out of paper bags - and this is just my short list.

除了这些，我还堆积木，用纸折飞机组成飞行中队，给玩具士兵列队，坐在电视机前看《活宝三人行》，把吃完的玉米棒插进纸杯里，看漫画，收集硬币和邮票，收集棒球卡片，给我在泽西海滩收集的贝壳上色，学了一点点吉他，跟我哥哥摔跤，让我的宠物龟爬上我的胳膊，用毛线逗小猫，梳过怪异的发型，用纸袋制作了手指木偶：这还只是我儿时活动清单的一小部分。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
