实际时间

Although from the seventeenth century onward Antinomianism does not appear to be an official doctrine of any of the more important Protestant sects, at least it has undoubtedly been held from time to time either by individual members of sections, and taught, both by implication and actually, by the religious leaders of several of these bodies.

虽然从十七世纪起， antinomianism ，似乎没有一个官方学说的任何更重要的新教教派，至少它无疑已经举行的时间，时间不是由个别议员的部分，和教导，双方的含义和实际，由宗教领袖的几个这些机构的工作。

IsIs so lves the currently existed practical bondage and reduces the time spent in making circuit board and waste of bank roll and time resulted from the inaccuracy design, playing an important role in improving product development efficiency and decrease of development cost.

它解决了一些实际存在的束缚，节省了大量的制作电路板的时间并减少了因设计错误导致的资金、时间的浪费，对提高产品的开发效率，降低开发成本等有重要作用。

When we spent much time on the internet and watching TV, bodiless "virtual" communication may be less psychologically satisfying than actual conversation, because it reduces time between us and our families, friends.

当我们花了很多时间在互联网上和观看电视节目上，无形的"虚拟"通信可能没有实际对话更能满足心理上的需要，因为它缩小了我们和我们的家人、朋友在一起的时间。

Often the actual chip-production time is less than 30% of the total cycle time.

Objective To study the power spectrum density of blood flow ultrasonic Doppler signal using wavelet analysis. Method Doppler signal of blood flow in human common carotid artery was studied with wavelet scalogram analysis, an affine smoothing Wigner Ville transform with a constant "Q" character. Result Wavelet scalogram of blood flow ultrasonic signal had a higher distinguishability than STFT spectrogram in the low frequency portion, but had poorer decussation terms than spectrogram.

对于平稳信号的处理工具仍然是Fourier变换，但是，在实际应用中的绝大多数信号是非平稳的，现在看来处理非平稳信号的主要工具将是小波变换，这主要是因为传统的Fourier变换分析信号时，时间和频率分辨率精度是固定不变的，而利用小波变换分析信号，在信号高频段时间分辨率精度也较高，在信号低频段频率分辨率精度较高，这很符合非平稳信号的特点。

Furthermore, to counter the uncertainty of the processing time in the practical production process, this paper builds a single machine earliness/tardiness with fuzzy processing time.

本文针对实际加工过程中作业时间的不确定性，研究了任务加工时间为模糊区间的单机提前／拖期问题，提出采用模拟退火算法对该模型进行求解，仿真结果表明，该方法具有较强的实用性。

The main results are as follows:We review the existing Monte Carlo control variates estimators of the price of Asian options and propose a new one. According to pratical needs, we define efficiency as the inverse of the product of the variance of an estimator and its computational time and make it a standard for comparisons to draw the following conclusions: Firstly, the more control variates correlate with arithmetic average Asian options, the larger is the efficiency of an estimator with these control variates, but among which the geometric average option plays the most important role; Secondly, an estimator with more control variates is better than one with less ones only when the time to maturity is long and the volatility is high.

在综合已有研究工作的基础上，本论文的主要创新成果如下：（1）我们回顾了已有的亚洲期权价格的蒙特卡罗控制变量估计，并提出了一个新的控制变量估计，且从客观实际出发，将估计值的方差和计算时间的乘积的倒数定义为效率并以它为标准比较各估计，得到以下结论：与算术平均亚洲期权相关程度越大的控制变量构成的估计的效率越大，而其中起主要作用的控制变量为几何平均亚洲期权的价格；只有在到期时间较长且标的资产的波动率较大时，元素多的多元控制变量估计比元素少的效率大。

A novel photocatalytic reactor, which can use sun light and graniform photocatalyst, was developed and evaluated. Hydraulics studies show that the actual mean residence time was approximately 1. 5 to 2 times greater than the theoretical mean residence time, which is of great advantage for degrading the pollutants in the reactor, and that the high reaction rate can be obtained by increasing the rotational speed.

设计了一种新型提升式圆盘多相光催化反应器(exalting round-platephotocatalytic reactor，ERPPR)，该反应器的主要特点是能够利用太阳光和粒状催化剂，通过对ERPPR水力学特性的研究发现，该反应器的实际平均水力停留时间约为理论平均停留时间的1.5到2倍，反应器内循环流量与提升桨转速成正比。

Based on those analyses and conformed international and national economic condition in china and some intrinsic defects of target zone regime, author transform target zone exchange rate regime by dividing two layers and bring forward a new exchange rate regime: double-layer-monitor exchange rate regime, the new model have possessed two merits, one is that the new model make "hollymoon effect" of target zone recurrence,and the merit can alleviate the fluctuation of exchange market;another merit is that the new model is a self-regulation system, that is say, the model can avoid long-term misalignment of exchange rate, those merit have major significance for china economy sustainable development and Chinese financial system more perfection, in paper we also present some fiscal policy and money policy served as a foil to double-layer-monitor exchange rate regime in order to make it work well, at last, we conclude that the new model will be the prior selection of RMB exchange rate regime reform for a long time form now on, and it also can serve as the bridge of RMB exchange rate regime steering to one of bipolar—free float.

在这些分析的基础上，并考虑到当前中国所面临的国际国内经济环境，针对汇率目标区的一些固有缺陷，笔者又对汇率目标区模型进行了分层改造，提出了一个新的汇率机制模型：汇率目标区双层监控模型，该模型有两个主要优势，一是可以使&蜜月效应&得以重现，从而避免外汇市场的过度波动；二是该模型是一个自稳定系统，能够进行自我调整，使实际汇率同长期均衡汇率保持一致，从而避免实际汇率的长期错位。这些优点对于我国经济的可持续发展，对于我国金融的更加完善，有着十分重要的意义。为使汇率目标区双层监控模型良好运行，论文还就相应配套的财政政策、货币政策措施作了探讨。最后得出结论，按照汇率制度&并存继起&假说，今后很长一段时间内，汇率目标区双层监控模型都将是人民币汇率制度的合意选择，另外，它也可作为人民币汇率制度向独立浮动制过渡的桥梁。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
