Comment on Students-Centred Service System

以学生为中心服务体系摭谈

This decreases the money multiplier, and therefore, the money supply for a given level of Central Bank money.

这减小了货币乘数，因此，一个给定央行货币水平的货币供给也减小（词不达意）。

The reforms come as central bank money data for October showed the first evidence of capital outflows since 2007.

这些改革措施出台之际，中国央行发布的10月份货币数据提供了2007年以来首个资本外流的证据。

The first is that sooner or later the increase in central bank money will lead to inflation.

第一个担忧是，央行加大资金供应迟早会导致通胀。

Those deposits are called reserve balances and are the key component along with currency of base money or central bank money which ultimately brings about changes in broader money supply measures.

这些存款叫做准备金余额，与通货一起作为基础货币或中央银行货币的重要组成部分，最终将带来更广泛货币供应衡量指标的变化。

The analyzer presented in this paper uses steam injection to heat and centigrade scale to display data and can be used to conduct displacement test for sample tubes made of different materials. As aresult, this experiment has a remarkable improvement in testing and teaching results.

本文介绍的仪器采用蒸汽喷射加热，百分表显示数据，可对不同材料制做的样管置换测试，使本项实验的测试结果和教学效果得到显著改善。

However, the temperature was not as yet much lower, and a centigrade thermometer, transported to Lincoln Island, would still have marked an average of ten to twelve degrees above zero.

可是目前的气温还不大低，如果林肯岛上有一只摄氏寒暑表量一下的话，平均温度一定还保持在零上10度到12度左右。

We get used to using a centigrade thermometer.

我们习惯用摄氏温度计。

Analyses and calculations show that, by ambient temperature higher than 1 centigrade degree, the system should be equipped with radiators to keep the temperature of working oil below 60 centigrade degrees.

分析计算表明，气温在1℃以上时，为保证工作油温不超过6℃，必须在系统中增加散热装置。

The thermal expansion measurements were made at 0 and 90 centigrade degree to the fiber axis in the temperature range from room temperature ( RT) to 400 ℃.

测定的温度范围是从室温到400℃。

And when the temperature of influent increased 1 centigrade degree, the specific flux of membrane increased 2.42 percent.

水温对膜比通量有较大影响，水温每升高1℃，膜比通量约增加2.42%。

The average global temperature has increased by almost 0.5 centigrade degree over the past century;

全球平均气温比上个世纪增长了大约0.5度。

A general program using APDL ( ANSYS parametric design language), which is applicable to arbitrary lining sections of the three-centered circular arch with different surrounding rock pressure distributions, was developed for the calculation of the tunnel inner forces and eccentricities.

利用ANSYS的参数化高级设计语言，编制了适合任意三心圆拱衬砌断面和不同围岩压力分布形式的隧道衬砌内力和偏心距的通用计算程序。

A fornltila for calculating the heading section of arbitrary three-centered arch and circular arch types was derived in this paper.
