My husband's simple prescription change your work schedule to do your most important tasks when you're most on you're A-game is similar to the advice given by Winifred Gallagher, author of the recently-published book "Rapt," about the science of paying attention.

丈夫向我提出的简单方案就是"调整你的工作安排，在你状态最好的时候做最为重要的工作"，这类似于加拉赫所给出的建议，她最近出版了一本有关如何集中精力的书《全神贯注》。

Because of the consumer\'s higher desire for the variety and freshness of the product and increasingly stricter administrative supervision in quality control, supply chain management with deteriorating item becomes extraordinarily important. Supply chain management with deteriorating item has been attracting wordwide academic and industrial attentions.

易逝商品作为一种特殊的商品形式具有质量不易保障、价值下降迅速、生产集中而消费分散等特点，同时顾客对品种的多样性、新鲜程度的要求越来越高，以及质检部门对产品安全的管制日趋严格，其供应链管理的重要性相对于非易逝商品更为显著。

Compared with point sources, Non-point sources are usually that various lashed pollutants which move and transfer with water and soil to acceptive water body because of storm's dynamic action and surface runoff.

点源是指通过排放口进行集中排放的污染源；非点源，是相对于点源而言的污染源，通常意义的非点源是指由于暴雨的动力作用，地表产生径流，各类污染物质随水土迁移，对受纳水体形成的冲击性污染。

The crystallization temperature and pressure of clinopyroxene phenocrysts from the ankaramite and basalt were estimated on the basis of the clinopyroxene-melt equilibrium principle: 1345～1366℃ and 1.75～2.05Gpa for ankaramite, with average geothermal gradient of 20-24℃/km, suggesting anomalous heat or geothermal gradient in this region may be one of the key reasons to produce the porphyry copper deposits in the region. In contrast, those in the basalts fomed under a relatively low crystallization temperature (1129～1191℃), and the pressure (1.19～1.60Gpa) and depth (39～53km), suggesting that the basalt formed under a condition of lower temperature and pressure.

根据单斜辉石-熔体平衡原理计算了富辉橄玄岩和玄武岩中斑晶相辉石形成的温度和压力，前者变化范围主要集中在1345～1366℃和1.75～2.05GPa，其深度相当于58－67km，平均的地温梯度大约20～24℃/km，说明该区具有异常的热或地温梯度，这可能是导致本区斑岩铜矿形成的主要原因之一；后者的温度和压力都相对较低，分别为1129～1191℃和1.19～1.60Gpa，而相应的深度为39～53km，暗示着玄武岩是在相对低温低压的环境中形成的演化岩浆。

A very specialized feeding adaptation in zooplankton is that of the tadpolelike appendicularian who lives in a walnut-sized balloon of mucus equipped with filters that capture and concentrate phytoplankton.

浮游动物体内一种极特殊的进食适应性变化是蝌蚪状的尾海鞘纲动物的那种适应性变化，而尾海鞘纲动物则存活于核桃大小的黏液球囊内，装备有过滤器，用以捕捉和集中浮游植物。

In the end, transportation of PAHs in the environmental matrix was preliminarily investigated and discussed according to PAHs data of soils and sediments from a certain region in Shanghai. The result indicated that there are two or more pathways on PAHs transportation in the environmental matrix.

最后，对上海特定地区内PAHs在环境介质中的迁移径途进行了分析讨论，结果表明上海市土壤和沉积物等环境介质中PAHs的迁移存在多种途径。
