查询词典 exist

A solipsist, in case you don't happen to know the word, is one who believes that he himself is the only thing that really exists, that other people and the universe in general exist only in his imagination, and that if he quits imagining them they would cease to exist.

所谓惟我论者---假如你碰巧不知道这个词---就是这样一个人：他相信自己是惟一实际存在的东西，而他人及整个世界只存在于他的想象之中，如果他停止对他们的想象，那么他们便会消失。

They must exist in pair and no side can exist solitarily.

两者必须成对存在，不可能独立存在。

The inventory cost is a primary component of the supply chain cost, and the method for multi-echelon inventory optimization and control must be adopted for the sake of the entire supply chain optimization and control, t present, papers on multi-echelon inventory systems have solved some problems, but they still have limitations. Firstly, they assumed that leadtime are constants. In practice, as the unknowable incidents exist in production, transportation and distribution processes, leadtime usually are uncertain. Secondly, there exist the hypotheses of totally back orders or completely lost sales under the condition of stockout in most literatures. Thirdly, the existing two-echelon inventory approximate model optimum always fixes one variable in the inventory strategy, and then seeks the optimal in the remained parameters, which makes the result can not be the best outcome.

目前有关两级库存优化控制的研究文献大多是假设提前期为常数的基础上建立模型，然而现实中由于供应链上各节点的库存不确定性以及运输、生产、交货等环节的不可预知性，使得提前期在多数情况下是不确定的；而且大部分文献都是假设缺货情况下要么完全延迟交货，要么完全损失销售，很少有考虑部分损失销售情况下库存优化控制的；另外，现有的两级库存近似模型的优化大都是固定一个库存策略中的变量，对余下变量寻优，其优化结果不可能是最优结果。

I think tomboy are still exist now and will exist in the future.

We first drew a total regression on the data of 30 regions from 1997 to 2005 and find that material capital elasticity of economic growth has a tendency of decline. Wile the human capital elasticity of economic growth showed a strong volatility. Then our research was focused on how human capital was influenced by economic growth among the four major part of China. The conclusion is. the human capital elasticity of economic growth in coastal areas, central areas and western areas of China increases when time goes by. When it comes to northeast areas, it is quite another situation: discrepancies do exist among regions, but do not exist among these years.

首先对我国从1997年至2005年30个地区的数据进行总体回归，得出结论为经济增长对物质资本的弹性有着下降的趋势，对人力资本的弹性则呈现较强的波动性；然后再分析我国四大区域之间，人力资本受经济增长的影响情况，得出的结论为，沿海地区、中部地区、西部地区的人力资本对经济的弹性都随着时间推移而增加，但是东北地区在这几年间的基本是不存在差异的，而且地区之间的也是有着较大差异的。

Some of the oldest open problems in mathematics relate to the abundancy index of a number. Are there infinitely many perfect numbers? Does there exist an odd perfect number? Does there exist an odd multiply perfect number? Such questions have been considered for well over two millennia by the likes of Euclid, Fermat, Descartes, Mersenne, Legendre, and Euler.

暑期的数学研究已渐渐步入正轨，今天上午和导师讨论的时候提出了第一个conjecture，说是虽然6和12的倍数的abundancy index比较高，但是如果把两个相邻的数字相乘，他们乘积的abundancy index总体来说会甚至更高。

Results: 1. The depression patients in neuroendocrine abnormity make up 59.4% of the total. 2.
