查询词典 U-steel

An extra force is produced using the piecewise-constant MS model during the segmenting. In each time step, the additional force is added to reinitialize the level set function, advance the speed of the curve evolution. Otherwise, a nonlinear function Ψ is introduced to instead of u+ and u-for edge preserving in MS model.

该方法在分割过程中利用分段常数MS模型产生一种驱动力，在每个时间间隔加入这种驱动力来推动水平集函数的进化，提高曲线演化速度；另外，通过在MS模型中引入一个非线性函数Ψ代替u+和u-实现保边。

The Crest of U-Flotilla 1, an unofficial emblem worn on the cap, as seen in the photo of Herbert Werner U-593 who also wears the laughing sawfish emblem.

U-Flotilla 1艇队的帽徽：一种戴在帽子上的非正式徽章。下面的照片是一名U-593上的军官，我们可以看到该徽章与笑口锯鳐徽章同时出现。

By taking a variation on U with as a variable, one arrives at the stationary equation given by (2.110) and the stationary value of U, Us is given by 式中D

通过用 作为U的一个变量，由式2.110得到的固定方程式和U的固定值Us由下式得到

Another says that originally it was U superimposed over an S, for U.S. of course.

另一种说法是：原来是字母U加在字母S上，当然代表U.S。

This method is based on moving average techniques, a statistics Uis calculated and opimized within a variable-sized moving window centred at an arbitrary sample location. The optimal statistic U(r0) characterizes the entities present in an image,therefore the U-statistic method usually provide better results in geochemical pattern recognition.

建立在移动平均技术基础之上，对任意一个样品位置，以该样品为中心具有窗口大小r可变化的移动窗口内，可计算出窗口内的一组样品所确定的统计量U值，根据统计量的最佳值U(r0)所成的图像，可以更好的反映相邻样品间存在的空间相关和变化特征，有助于地球化学模式识别和异常筛选。

If block u is not already in memory and there is an unassigned block buffer, transfer block u from mass storage to an unassigned block buffer.

如果区块 u 并非在记忆体中，并且有一个未分配的区块缓冲区，从大量储存媒体传送区块 u 到一个未分配的区块缓冲区。

MATERIALS AND METHODS: The newborn mice were divided into DES, urethan and U+ DES groups. U was given in 500 mg/kg dose ip on the 14th day after they were born. DES was administered by ip on 1 d, 8 d, 15 d in the doses of 1/7, 2/7 and 4/7 LD50 of the day of treated.

材料与方法：ICR新生鼠，分设DES、乌拉坦和U+DES组。U在14d以500mg/kg腹腔注射(intraperitoneal，ip)；DES分别在1d、8d、15d ip，共3次，分别以注射日龄LD50的1/7、2/7、4/7为DES低、DES中、DES高组。

:at any point of elastic object ,the rotating value of z axis is :ν u θz = substitute get:ν= u = y x θz = 0 x y into the formula , we can Similarly:θx = 0 θy = 0 So the rotating values of the three coordinates at any point of the elastic object are zero.

：在弹性体的任一点处，该点对z 轴的旋转量ν u θz = x y u =ν=将代入，可得： y x θz = 0 同理θx = 0 θy = 0 即弹性体的任一点对三个坐标的旋转量都等于零。

32 U/mL enzyme activity can be detected in medium after fermentation. By optimizing the zymotic medium and fermentation conditions, recombination B. subtilis can express as high as 110.02 U/mL of Alkalineβ-mannanase. Cycle of fermentation needs 5 days(4 days is needed in induced expression ), then enzyme activity maintained at the highest level, less than 5 % enzyme activity was lost in next 2 days.

为了继续对碱性β-甘露聚糖酶进行高表达研究，试验采用了芽孢杆菌发酵培养基来进行产酶研究，初步诱导酶活达到29.32 U/mL，通过对发酵条件的优化，该重组枯草芽孢杆菌的产酶水平有了大幅度的提高，最高可达110.02 U/mL。

METHODS:We recorded the cardiogram by perfusing garlicin injection and garlic preparation to the isolated heart of rabbits by Langendorff method,examined the minimum dose of asystole. RESULTS:The minimum fungistatic concentration of garlicin injection was 3～6.2 times lower than that of garlic preparation. The minimum dose of garlic preparation is 0.1736 u/ml, and that of garlicin injection is 3.919 u/ml.

采用Langendorff法对兔离体心脏分别灌流大蒜素注射液、大蒜注射液、大蒜实验液，分别记录心搏图，求出致心脏停搏的最小剂量，结果：大蒜素注射液的抑菌浓度为大蒜实验液的1/6.2～1/3，而致心脏停搏的最小浓度分别为0.1736 u/ml和3.919 u/ml。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
