查询词典 at a cost

Because the expensive tunable laser is not available in laboratory, the high-luminosity halogen lamp is considered as the multiplex photosource, at results, the cost become lower and the program keep more practicable. A experimental scheme of 16 channels wave demultiplex based on volume holographic technology is designed, and its channel capacity, noisiness, cut-in loss, isolation and storage persistence are analyzed.

Based on the theory of agency, the theory of property rights and the theory of the ownership structure of the firm, Michael C. Jensen developed a hypothesis of free cash flow. He points out "Conflicts of interest between shareholders and managers over payout policies are especially severe when the organization generates substantial free cash flow. The problem is how to motivate managers to disgorge the cash rather than investing it at below the cost of capital or wasting it on organization inefficiencies."

在借鉴资本结构论、公司控制权市场论、契约论等研究成果的基础上，詹森提出了自由现金流量理论，该理论主要讨论了股东与管理者之间存在的代理成本问题，认为股东应该"促使管理者吐出这些现金，而不是将剩余现金以低于资本成本的收益率进行投资，或者在低效率的组织中耗费"。

Dollar cost averaging cannot make a high-risk investment entirely risk-free, but it can help manage the risk of your investment portfolio – and help you sleep better at night.

平均成本不能作出一个高风险的完全无风险的投资，但它可以帮助管理您的投资组合的风险-并帮助您在晚上睡得更好。

One type of formula investing, called dollar cost averaging, involves putting the same amount of money into a stock or mutual fund at regular intervals, so that more shares will be bought when the price is low and less when the price is high.

有一种程式投资叫美元成本平均法，按均匀的价格间隔，用相同的资金投资于一种股票，或者一个共同基金的股份；当股价处于低位时买得多，当股价处于高位时买得少。

The Dollar Cost Averaging Return is calculated by comparing the total contributed amount over the specified period with the final NAV. A constant amount is used to purchase fund units at the prevailing fund price on the last

平均成本法回报的计算是在指定期内将最终资产净值比较总投资金额得出；方法是在每月最后一个交易日定额投资同一基金内，以当时基金价格购入适量基金单位，总投资金额则等於在指定期间内每月供款的总额；而最终资产净值则由在

The whimsy of the British performance at the Olympic handover, featuring twirling umbrellas and a doubledecker bus, suggested that Britain would not attempt to match the pageantry and stadiums that cost China billions.

在奥林匹克移交时英国表演的与众不同的幽默感，旋转的伞以及一部两层的公车，预示着英国不会尝试壮丽的展示以及象中国那样花费上亿的建造露天大型体育场。

By Laurie Barclay, MDJanuary 21, 2009 — Success in the primary care setting of either step-up or step-down treatment of new-onset dyspeptic symptoms is similar, but the step-up strategy is more cost effective at 6?months for initial treatment of patients with dyspepsia in primary care, according to the results of a double-blind, randomized controlled trial reported in the January 17 issue of The Lancet .

January 21， 2009 —根据一项刊登在1月17日Lancet的双盲、随机分派研究结果，在初级照护下，以进阶或是降阶治疗新发生消化不良症状的效果是相当的，但是进阶治疗策略对消化不良病患的起始治疗而言，在治疗6个月后更符合经济效益。

Compared with rare-earths and their alloys, the perovskite-type manganese oxides exhibit higher chemical stability, higher resistivity that favors a lower value of eddy current loss and lower cost, and would be more suitable candidates for magnetic refrigerants at high temperature, especially the potential for application near room temperature.

与稀土以及稀土-过渡金属的合金比较，钙钛矿锰氧化物具有较高的电阻率有利于降低涡流损耗，以及较低的价格，因而这类材料有可能是高温，特别是室温磁制冷的较好候选者。

The oil sewage disposed process is a complex disposal technique. The disposal process is more difficult for the change of PH Flux temperature of raw water and the other polluted quality. At present the disposed water by the system of oil of sewage is unstable and high cost. Now the method for the oil of sewage have physics chemistry physical chemistry and biology etc. In the every disposed method has its own specially, Basis of the oil sewage condition of power plant. The text use chemic method. Another word is method of Flocculation-deposition. Injecting Dosage into sewage. Making small suspends grain and the electrophorus colloid gather into bigger colloid and deposit. Separated it from water and purify the oil sewage. Make disposed oil water up to grade.

含油污水处理工艺是一个复杂的处理过程，在处理过程中由于受到原水浊度、PH值、配水流量、原水温度和其他水质污染等因素的影响，处理难度相当大，现时的含油污水处理系统普遍存在处理后的水质不稳定和处理成本高等问题，国内外含油污水处理采用的方法有物理法、化学法、物理化学法和生物法等，每种处理方法都有自己的特点，结合电厂含油污水的情况，本文主要采用化学法，具体来说是采用絮凝沉淀的方法，通过向废水中投加混凝剂，使细小的悬浮颗粒和带电胶体微粒聚集成较大颗粒而沉淀，使其与水分离，使含油污水得到净化，使处理后的废水各项指标达到排放标准。
