Were used; for filter-eeding experiment, the alga used was Nitzschia closterium, and the experimental temperatures were 20, 23, 26, 29℃.Results show that the feeding selectivity of small-ized bay scallop and the oyster increase with algae size:when the algae increased from 4.35m to 11.6m, the feeding rate of bay scallop increased from 4.21%to 11.0%and that of the Pacific oyster from 0.81%to 3.15%.

结果表明，海湾扇贝和太平洋牡蛎的小贝的摄食率随藻类规格的增大而增加；而大贝则表现出明显的差异，海湾扇贝对中等规格（＝5.55—5.79m）的藻类、太平洋牡蛎对小规格（＝4.35m）的藻类具有较高的选择性，表明相同条件下两种贝类对海洋浮游植物群落结构产生不同的影响。

When fed with the mixture of P. donghaiense and the diatom Nitzschia closterium, A. sauna preferred grazing on P. donghaiense to N. closterium, and the GCEs of A. sauna decreased with the increasing density of P. donghaiense. When exposed to A. catenella at the densities of 10 – 10^3 cells/mL, A. sauna lost weight with no Chlorophyll a detected in their guts, which indicated that A.

而当不同密度的东海原甲藻分别与一种硅藻小新月菱形藻混合投喂时，随东海原甲藻密度的增加，卤虫选择性地增加对东海原甲藻的摄食，而降低对小新月菱形藻的摄食，并且其总物质转化效率逐渐降低。

They are: conceptual meaning (logical, cognitive, or denotative content), connotative meaning (what is communicated by virtue of what language refers to), social meaning (what is communicated of the social circumstances of language use), affective meaning (what is communicated of the feeling and attitudes of the speaker/writer), reflected meaning (what is communicated through association with another sense of the same expression), collocative meaning (what is communicated through association with words which tend to occur in the environment of another word), thematic meaning(what is communicated by the way in which the message is organized in terms of order and emphasis).

在商务英语创意中常用的联想方式有接近联想、相似联想、对比联想和关系联想四种。合理地运用联想这一心理现象进行商务英语创意可以引起受众的关怀，影响受众的情绪与行为，使商务英语的效果更直接、更显著。从关联与认知语境的视角出发探讨联想在商务英语创意中的运用是有必要的。关联理论认为，话语的关联程度依赖于语境效果和处理努力，语境效果与关联成正比，处理能力与关联成反比。作者把处理努力理解为认知语言环境所消耗的脑力，关联性越强，话语就越直接，认知所耗的脑力越小，给受话者带来的认知负荷就越小；关联性越弱，话语就越隐含，消耗的脑力越大，受话人的认知负荷越大。

This in vivo study was to examine the historical changes of implanted novel chitosan/collagen composite barrier for confirming the clinical feasibility. Four other commercial GTR membranes were chosen for comparison. Among the resorbable GTR membranes, BioMend Extend and Peri-Aid are collagen base, and GORE-TEX OSSEOQUEST is synthesized membrane, while GORE-TEX e-PTFE (Expanded polytetrafluoroethylene) is synthesized but non-resorbable. Beagle dogs were used as animal model. Buccal mucoperiosteal flaps were reflected in the bilateral mandibular premolar and molar areas. Buccal alveolar bone was reduced on 1st、2nd premolar and molar to a level 5 mm apical to the cemento-enemel junction. Root surface was denuded of periodontal ligament and cementum, and notches were placed at the bone level of each root. The tested GTR barriers were implanted in critical bone defect areas. Flaps were coronally positioned and sutured. Two beagle dogs were sacrificed each time as the designed time period after surgery. Histological and histometirc evaluation at 7 days、14 days、28 days、3 months were performed post-operatively to determine the healing response of each treatment modality.
