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.

材料与方法：搜集术前行乳腺MR检查并经穿刺或手术病理证实的236例乳腺病变，以对侧正常乳腺腺体作为正常对照，采用横轴位的平面回波-扩散加权成像序列，TR=8400ms，TE=93.8ms，层厚=4mm，激励次数=2：视野=30×30cm，矩阵=128×128，ASSET=2，b值=0和1000s/mm~2；参考动态增强图像准确定位，测量病变区和对侧正常乳腺腺体的ADC值，应用t检验比较良、恶性病变及正常腺体ADC值的差异，采用接收者工作特征曲线(receiver operating characteristic curve，ROC)确定良恶性病变的ADC界值；根据BI-RADS MRI将乳腺病变按照形态学表现分为肿块性病变和非肿块性病变两组，比较ADC值在肿块和非肿块性病变中定性诊断的效能。

This " computer signs up for " march the net swims the market, also can be regarded as planar media to seek what profit gains a point newly to try benignantly again.

此次《电脑报》进军网游市场，也可以被视为平面媒体寻求利润新增点的又一次有益尝试。

The results show that the Zn complex can be partially intercalated into the double helix of DNA due to the planarity of the benzimidazole ring and the bulky structure of the complex.

实验结果表明，由于配合物的八面体构型以及苯并咪唑环的平面性，其与DNA作用方式可能为部分插入。

The basic idea is as follows: first, a kind of plane α-B-spline interpolation curve with a shape control parameter a is constructed; then, by converting the first derivatives of the curve into Bernstein polynomial, the positive conditions of Bernstein polynomial can be used to get the necessary and sufficie nt conditions for the monotonicity of α-B-spline interpolation curves, i.e., the range of the parameter a. Therefore, monotone-preserving interpolating curves can be obtained succinctly.

其基本思想是：首先构造带有形状可调参数的一类平面(-B样条插值曲线，再把其一阶导矢的两个分量分别转化为Bernstein多项式，从而利用Bernstein多项式的正性条件，得到此曲线为单调的充要条件，即形状参数的取值范围，简单、快捷地实现此参数样条曲线的保单调插值。

Let's try out the best approximation then: a plane.

让我们来试试比较好的近似方法：一个平面。

The background of the sword is black, whose surface is bestrewn with silvery white multi-cycle and multi-line patterns. All of them are made of plane and natural patterns. Though pictures can be taken for them, they are not to he made into rubbings. They do not lack ease and grace, but they are still subjected to certain rules.

该剑底色青黑，其上满布银白色重圈纹和组丝纹；它们都是平面花纹、自然花纹；看得见，难触摸；可摄影，不可拓摩；既自然流畅，又有一定规则。

Two rules joined together as adjustable arms used to measure or draw angles of any size or to fix a surface at an angle.Also called In this sense, also called bevel square

斜角规：组合在一起作为可调节臂的两把刻度尺，用以测量或描划任意大小的角或以某一角度固定一平面也作在此意义上也可称作 bevel square

The focusing effect by anyone of the biconcave erythrocyte, oblate spheroid,and disk sphere erythrocyte was found to be so remarkable that the light intensities at the focused areas close to the erythrocyte membrane were about 10 times higher than that of the incident light when the light irradiated along the erythrocyte plane.

我们发现会聚效应在双凹型，扁球体型或圆盘球体型红细胞中的任何一个都如此显著，以至于当激光照射方向沿着红细胞平面时在靠近红细胞膜的会聚区域的光强达到入射光强的10倍多。
