As an example, a method to put the point of unit Fresnel number to infinity is suggested and demonstrated.

作为一个例子，提出和验证了在发散球面波入射情况下可将菲涅耳数等于1的点拉至无穷远的结论。

The distance from the point where it enters the frontalis to supra-orbital foramen is 40.2±9.1 mm, the vertical and horizontal distances from the point that it enters the frontalis to supra-orbital foramen are 33.8±8.4 mm and 30.5±8.8 mm respectively.

眶上神经起始部直径1.4±0.3 mm，本干入肌点至眶上孔的直线距离为40.2±9.1 mm，水平距离和垂直距离分别为 30.5±8.8 mm和 33.8±8.4 mm。

If the steel wire rope is moved to a prior calculated point on the gasholder top,the measuring error will decrease considerably.

将柜位计的计量钢绳移至柜顶计算好的点上，可以较好地弥补这一误差。

When up to 31th harmonics are analyzed, the calculation time is only 1/82 of theat by the classical Gaussian elimination method.

对于一个周期值事先不知道，在一个周期内有100个采样点的非整周期采样，这个近似方法可使谐波分析的准确度由一般的DFT的10〓量级提高到10〓量级；当分析至31次谐波时，计算时间约为经典高斯消去法的〓，将能满足实际的工程需要。

If average values before or after catastrophe point when the pressure at both ends reduces exceed the threshold value, judging that there is leak and positioning: calculating approximate wavelet transformation coefficient of pressure data at both ends, initializing searching interval, calculating a signal time delay value corresponding to approximate wavelet transformation coefficient in the searching interval from maximal scale N; converting the time delay value under scale N to that under N-1 by geometric proportion relation; updating the searching interval, repeating above processes until the scale is 0 and positioning based on the time delay value.

若两端压力下降突变点前后的均值变化均超过阈值，判定有泄漏并进行定位：计算两端压力数据的近似小波变换系数，初始化搜索区间，从最大尺度N开始在搜索区间内计算对应近似小波变换系数的信号时延值，利用等比关系将尺度N下的时延估计值转换为N-1下时延估计值，以该值更新搜索区间，重复以上过程至尺度为0，以此时延估计值进行定位。

Results: All rats in experiment group devloped CAG at the end of 12 weeks with the following Pathological changes of CAG such as thin mucosa layer, thick muscle layer, decreased glandes, soakaging inflammation cells in microscope and with the time prolonging, the atrophy of gastric mucosa became more serious; In normal control group and normal feeding group, the IL-6 and IL-8 content in blood serum are the same at every time point; In experiment group, IL-6 became increased from 4wk and kept high level from 4wk to l2wk and had significant difference compared with normal controls.

结果：灌胃至12wk时出现胃粘膜层变薄，固有层腺体减少，固有层纤维结缔组织增生，粘膜肌层明显增生，慢性炎细胞浸润等萎缩性胃炎表现，随著热盐水灌胃时间的延长，32wk胃粘膜萎缩程度明显加重；正常对照组和正常餵养组大鼠各时间点血清IL-6，IL-8含量基本相同。

TITe is go to be a lecture, titled "Across Cultures: Digital Media and Literate Activity", in the meeting room of the English Department from

通知 7月11日周一上午9点至11点将在英语系会议室举办一场题为"跨越文学：数码CCTV和文学聚会"的讲解座谈会。

On the water students must : sail on all points of the wind and tack and gybe in a wind of at least 15 knots , sail a compass course to within 10 degrees , carry out a man overboard recovery in darkness .

对水的学生必须是：帆上所有各点的风向和角度阐述和 gybe 在风力的至少有15海里，航行一个指南针，当然要在10度，进行了男子过火复苏，在黑暗中徘徊。

Flow cytometric also used for analysis the levels of reactive oxygen species, Ca2+ and mitochondrial membrane potential in both cell lines. The results showed Gyp promoted ROS and Ca2+ production and decreased the MMP level. Western blotting show that Gyp treatment gradually decreased the levels of anti-apoptotic protein (Bcl-2), but increased the levels of the pro-apoptotic protein.

除此之外，也藉由流式细胞仪分析测得经绞股蓝皂甘作用后的人类血癌细胞（HL-60）和小鼠血癌细胞（WEHI-3）里的活性氧化物浓度上升、钙离子释放以及粒线体膜电位下降等细胞凋亡重要指标，此结果可经由西方墨点法指出绞股蓝皂甘能使癌细胞中的抗凋亡蛋白Bcl-2表现量下降；促凋亡蛋白Bax表现量上升，同时也藉由共轭焦显微镜观察到致死蛋白AIF、Endo-G从粒线体释放至细胞核。

James Hardie, which gets more than three-quarters of its sales from the U.S., fell 9.6 percent to A$3.78, on track for its largest drop since Nov.

詹士哈迪，其中获得超过四分之三的销售额来自美国，下跌百分之九点六至3.78点，跟踪其以来的最大降幅11月 19日。

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。
