"There are two types of oyster farming: suspension culture, in which oysters are grown off bottom, in floating trays, is a labor-intensive form of cultivation that requires continuous tending and cleaning of both gear and shellfish, and bottom culture, which is similar to conventional crop farming on land; it involves selecting areas of the sea floor that provide a natural food supply, necessary currents, minimum exposure to predators, and proper temperature and then ""seeding" the bottom with shellfish stock that are left to grow to market size.

中文解释=有两种典型的牡蛎养殖场︰悬浮养殖，牡蛎不接触海水底部而在悬浮的箱架中生长，属於劳动力密集型式的养殖方式，工具和贝都需要经常照顾和清洗。底部养殖，类似於传统的在土地上种植农作物，需要选择能提供营养物、必须的水流、被捕食者接触的机会最小、和适宜的温度的海底地，然后将贝类&种植&在海底，让它生长到市场所需的大小。

Research found, generally speaking, students' concept image is not fully covered about quadrilaterals. That is to say, some graph is excluded wrongly. For example:students took oblique square is rhombi, not square. This phenomenon probably caused by they see the typical shape all the time, which will impact the development of the higher level reasoning. Say, students might not be able to understand the inclusion relationship between square and rhombi.

研究发现，学生在四边形几何图形的概念心像上普遍有包含性不足的情况，也就是有些图例被错误地排除（如：以为斜摆的正方形是菱形，但不是正方形），此一现象应与学生接触的通常是典型图例所致，且会影响更高层次的几何推理之发展，例如无法理解正方形与菱形的包含关系。

Using the classic plot survey method （survey area is 7 200 m^2）, niche breath and niche overlap values of ten dominant species were calculated, with layer as one-dimension resource state and abundance as index, in the Pinus kwangtungensis community in Nanling National Nature Reserve of Guangdong.

在广东南岭国家级自然保护区广东松Pinus kwangtungensis群落内，通过典型样地调查（调查面积共7200m^2），以不同林层作为一维资源位，以个体多度作为计测指标，计测了广东松群落中10个优势种群的生态位宽度和生态位重叠值。

Combined with dumm y damping parallel circuit,the voltage prediction can eliminate partially the sam pling tim e delay of input and output data transfer thus resulting in current noise reduction and a numerical stability im provement,which can achieve an overall simulation stability in steady and transi...

利用电压预测技术，结合&虚&阻尼并联支路，可以有效地减小接口电流噪声，提高 RTDS数值计算稳定性，保证数模接口在稳态和暂态仿真中的稳定。各 AC/DC接口的电压预测步长需独立精心选择，典型值在 1个～ 3个步长，取决于直流平波电抗值的大小和直流输电线的长度。文中给出了接口的技术实现和性能校验结果。

The effect and its mechanism of temperature during grain filling on rice quality were investigated by using 4 eary-indica rice cultivars with different quality and amylose content. The plants at filling stage were transferred into two phytotrons (Model PGV-36, CONVIRON, Canada), which were set two mean daily air temperatures, i.e. 22℃, optimum temperature regime and 32℃, designed as high temperature regime. The differences in quality properties and starch characteristics of rice between two temperature regimes were determined, and effects of temperature at grain-filling stage on starch biosynthesis in developing rice grains were also analyzed.

本研究以田间异季栽培试验为基础，利用人工气候箱(PGV-36型，CONVIRON)设高温(日均温度32℃)和适温(日均温度22℃)两个典型温度处理，在日温差、光照、相对湿度等因素完全一致的条件下，系统地研究了水稻灌浆结实期不同温度对早籼稻米淀粉的DSC热力学特性、RVA粘滞性、晶体结构、淀粉链长分布等理化指标的影响及其品种类型间的差异，并分析了水稻籽粒淀粉合成代谢过程中几个关键酶的温度效应特征及其与稻米淀粉合成和积累的关系。

Focusing on all these functional traits, 13 functional groups were identified by TWINSPAN (two-way indicator species analysis), and their change with different environmental factors, disturbance types and recovery time was ordinated by DCCA(detrended canonical correspondence analysis).

本文以海南岛霸王岭林区作为海南岛热带林的典型区域，以反映不同环境因子、干扰类型和恢复时间的热带山地雨林为研究对象，在大面积(15hm~2)样地调查的基础上，依据物种的7个功能特性(喜光性、潜在高度、板根大小、木材密度、种子生物量、传播方式和落叶／常绿性)，分别把物种划分为不同类别的功能群，应用NMS分析了各功能群随不同干扰类型和恢复时间热带山地雨林群落的变化规律。

With its thick rubber armor, its large oculars with long eye-relief (suitable for use with gas-mask) and the eye catching window of its infrared detector re-charger, the DF had become the classical example of a full fledged military binocular, the blueprint of later 7x40 clones which adopted the same design philosophy.

身披厚厚的橡胶，长出瞳距离的大目镜和用于红外观测的受光窗，DF成为了军用望远镜全能地典型，后来的7x40望远镜的蓝图基于相同的设计这里克隆了该镜。

Can be said that cattle are typical of self-interest that they can stand and watch as his companions were emaciated wolf swallowed Li, but no one dared to stand up the ranks of thousands as weak as wood, without the wind, so they will never are weak, always abide by bullying them and no one is poor.

可以说牛是自私自利的典型他们可以眼睁睁地看着自己的同伴被瘦弱的狼吞唳，而没有一个敢站出来，成千上万的队伍就象木头一样弱不经风，所以他们永远是弱者，永远守欺压而没有人可怜他们。
