三次

This is my 3rd time to Penang Hill, the previous visit was 5 years ago.

这是我第三次到升旗山，前一次拜访已是五年前的事了。

Comment: Biphasic or prandial insulin, added to two-drug oral therapy, was more effective than basal insulin in achieving optimal glycemic control

评论：一天两次或三次的胰岛素用量外加两种药物治疗较基础胰岛素用量能更好的控制脂肪量。

Better glycemic control with biphasic and prandial insulins occurred primarily among patients whose baseline HbA1c exceeded 8.5%.

在HbA1c含量超过8.5%的情况下，一天两次或三次应用胰岛素能更好的控制脂肪摄入。

A set of quadruply coupled equations (fluid flow, convection-diffusion, energy conservation and mechanical equilibrium) with a number of cross-couplings and coupled constitutive relations is formulated to quantify the multi-physics of oil displacement by CO2 injection, implemented into and solved by using FEMLAB. FEMLAB is the first engineering tool that performs equation-based multi-physics modeling in an interactive environment. With FEMLAB, the coupled multi-physics model can be solved simultaneously. The applicability of this model has been demonstrated through an example of simulations for a two-dimensional reservoir of size 1000 m×1000 m with one injection and one production wells. Model results illustrate the significant importance of the cross-couplings between individual (thermal, hydrological, chemical and mechanical) physics.

首先，建立一套流、固、热、多相流等多场全耦合控制方程组及其相应的耦合本构关系；然后，采用FEMLAB为工具来模拟三次采油阶段CO2驱油过程中的流、固、热、物质守恒等多场之间的全耦合作用，是第一个人机交互式的基于偏微分方程组的多物理场耦合分析的工程工具，利用FEMLAB，该4个耦合方程组成的方程组可以一次同时被求解出来：最后，应用该模型来求解一个二维油田的驱油情况，数值计算结果表明，原位应力、注入温度、注入压力等因素对CO2的地下贮存效率、驱油速度等有重要影响。

The major achievement of this paper is: Based on characteristics of the traffic data distribution, execute pattern recognition operations on traffic condition on two dimensions by clustering, then use BP neural network to describe and forecast traffic flow aiming at each pattern. Making use of classic flow-occupancy inverse "V" model, implement polynomial fitting using least-squares algorithm and statistics method on flow curves to detect outliers which are proved to be not accord with practice through the actual implement, then use the moving average model to recorrect the outliers and absent. Make correlation analysis on muti-direction flow queues of the intersection and ones of upriver intersections, choose flow queue with high correlation as assistant one to improve the error tolerance of the prediction system, at the same time we can use the method to give an estimation of flow in intersection with out sensors. We design and implement an SOA(Service-Oriented Architecture)-based UTDD(urban traffic data mining development) with high expansibility and performance, which implement unified management and call of the data-mining application though defining a XML-based description of data-mining process and a common interface to call data-mining process, finally we build traffic flow prediction application model on UTDD.

根据交通流量数据分布的特征，提出基于k-means的二次聚类方法，对交通流量在流量大小和时间上进行模式划分，进而对各个交通流模式进行基于BP神经网络的描述和预测，从而提高模型对流量预测的精度； 2）根据流量/时间占有率倒&V&字形曲线分布模型，提出基于最小二乘法的三次多项式曲线拟合和统计方法的异常检测方法，实际应用表明该方法能够有效识别异常数据，然后根据移动平均算法对异常数据进行修正； 3）基于序列相关性分析，分别对预测方向的交通流量数据序列、上游路口相关序列以及预测路口其它各个方向上的交通流量序列进行分析，选择相似性流量序列，作为辅助序列提供其他没有检测器路口的流量估计； 4）设计和实现了基于SOA（Service-Oriented Achitecture）的高性能、可扩展的智能交通数据挖掘系统UTDD，该系统通过定义基于XML的数据挖掘过程描述和通用的过程模型接口，实现数据挖掘应用的统一管理和调用，最后在UTDD上建立了基于路口流量预测的应用模型。

Resumptively, the construction of new structure will change the third stress field to the fifth stress field in surrounding rock, and bring the safety problem of existing structure and the complexity problem of newly-built structure.

概括地讲，新建结构物的施工会使围岩从原来的三次应力场演变到五次应力场，正是这种应力的演变导致了既有结构和新建结构的受力变异，造成既有侧的安全性和新建侧的复杂性问题。

This technique can be utilized twice, but becomes treacherous on the third retracement.

此方法可以用两次，第三次就比较危险了。

Scratch me two,I will scatch you three.

你挠我两次，我挠你三次。

Stable temperature is important to thalli preservation.Cells survival rates drop largely after melting and freezing once andcells die wholly after melting three times.

保存中温度的恒定也非常重要，冻融一次以后细胞的活性大大降低，冻融三次则细胞完全死亡。

The scattered light from moving red cells is transmitted twice through the skin surface, so that random-modulated triply.

由于来自运动着的红血球的散射光两次经过皮肤表面，因而受到三次随机调制。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
