Materials and Methods:236 pathology-confirmed breast lesions(155 malignanty,81 benignancy) and 221 disease-free contralateral breast tissues were examined using EPI-DWIb values=0,1000 s/mm~2TR/TE=8400ms/93.8ms; FOV=30×30cm;matrix=128×128;ASSET=2,slice thickness=4mm.DCE-MR imaging was also performed for accurate location of the lesion using VIBRANT sequence.The mean ADC values of malignant and benign lesions and the disease-flee contralateral breast tissues were calculated from the ADC map for each patient.One-way analysis of variance was applied to compare the mean ADCs of malignant lesions with benign lesions and disease-flee contralateral breast tissues.The threshold ADC value for malignant lesion was determined using a receiver operating characteristic(ROC curve analysis.Each lesion was classified into two major types:mass and non-mass lesion.The diagnostic performance of DWI was compared in breast mass and non-mass lesions.Results:155 malignant and 81 benign lesions were confirmed in 236 lesions.

To use linear program, we have to take care of two problems. The first problem is that the actual relationship between intensity and duration is nonlinear convex function. In this study, we propose to use piece-wise linear curve to approximate the nonlinear convex curve. The second problem is that there are many feasible event sequences.

使用線性規(guī)劃遭遇的困難有二：第一，作業(yè)強度與作業(yè)時間呈非線性之凸函數(shù)關(guān)系，因此本研究將使用片段線性曲線(piece-wise linear curve)近似作業(yè)強度與作業(yè)時間呈非線性之凸函數(shù)關(guān)系日韩手机自拍无码专区；第二经典18岁黄片，專案有很多組可能事件順序，事件順序的不同會產(chǎn)生不同的資源限制式操屄无码，本研究提出一個系統(tǒng)化的方法求解問題黄色免费的网址。

Moreover we formulize the optimal path according to the theory of B-spline Curve, so the path which is composed by the grid point can transform into a continuous and smooth curve. By formulizing path we can also calculate angular velocity, angle acceleration, and torque in dynamics.

另外我們根據(jù)B-spline Curve的理論將最佳路徑參數(shù)化四川美女大白屁股黄毛片观看，使由格點所組成的最佳路徑轉(zhuǎn)換為一條連續(xù)且平滑的曲線，藉此我們也可以計算動力學(xué)中的瞬間角速度天天久久国产精品电影网、角加速度與力矩黄色网站在伦看。

And we by the NDR curve of the IV curve can be observed, NDR device has a very special non-linear phenomenon, Usually composed of a non-linear circuit components are usually chaotic phenomenon, so we raise our six different structure in addition to the new frequency, and to explore the phenomenon of chaos, and the use of the cycle of chaotic phenomena in addition to the frequency multiplier effect achieved .

而我們由NDR的I-V curve曲線可以觀察到，NDR元件具有非常特別的非線性現(xiàn)象欧美一级婬片A片九九精品，而通常一個非線性元件所組成的電路通常會有混沌現(xiàn)象国产精品又黄又大又硬，因此我們提出六種不同架構(gòu)的新型除頻器，并且探討其中的混沌現(xiàn)象人人干人人看人人插，而利用混沌現(xiàn)象中的周期倍增所實現(xiàn)除頻效果大黑吊插逼。
