Finally also must supplement, my indefatigable is also good, for instance returns to the news to the foreigner, that English language organization wants my life very much, had thought also must a letter letter press quite a while on the handset, spends the time very much, I have counted, a longest news I have sent 20 minutes, that also is I thought I send best section of speeches, wait for the reply complacently, finally sees this kind of news:"SORRY, I CAN NOT UNDERSTAND WHAT IS YOUR MEANING (is unfair to meaning which I do not understand you to say)!"
最后还要补充的是,我也有耐性好的时候,比如给老外回消息,那个英文语言组织很要我的命,想了半天还要在手机上一个字母一个字母地按,很费时间,我统计了一下,最长的一条消息我发了20分钟,那也是我觉得我发的最好的一段话,得意洋洋地等待回信,结果看到这样一句消息:&SORRY,I CAN NOT UNDERSTAND WHAT IS YOUR MEANING(对不起我不懂你说的意思)!&

Based on the separation technique of address and display, the subfields with higher weight value playing an important role in producing the dynamic false contour are divided into several subfields with lower weight value. The addressing method of accumulation lighting is adopted for the divided subfields. By comparing the gray statistic of input image with the preset gray level thresholds, the operating situation of the dismantled subfield is dynamically determined so as to reduce efficiently the false contour phenomenon without influencing the picture luminance.
该技术基于寻址与显示分离技术,将对产生动态假轮廓起重要作用的权值较大子场拆分为若干个权值较小的子场,并对拆分的子场使用累积发光的寻址方式,利用输入图像灰度统计与预置的灰度阈值比较,动态地确定拆分子场的使用情况,在不影响图像显示亮度的情况下有效地减小了动态假轮廓现象。

Many tree species at the same time and solve the spatial heterogeneity which empirical method could not achieve. Therefore, the assessment method could be applied in the selection of species for afforestation or species selection in the forest restoration areas.From collecting the attributes of planting species, spatial distribution data and environmental factors, we could integrate and analyze the data for further simulating the forest dynamics of forest in Taiwan. The impact of global change on forest also could be evaluated.
应用生育地因子评估树种之生态地位,能解决统计实证方法在空间异质性使用的限制,并可同时评估多种树种,因此可应用在造林树种之选择,亦可应用於崩塌地复育造林树种之选择,以及林相改良造林树种之选择,在收集更多树种属性与空间分布资料后,配合此评估方法,未来更可模拟出台湾森林之动态,以及评估环境变迁对台湾森林所造成的影响。

An equal cross-section blade was investigated and a finite element model was built parametrically. Geometrical parameters (such as length, width and thickness), material parameters (such as young's modulus and density) and speed of blade were considered as input random variables while the static frequencies and dynamic frequencies were output random variables. Combining the finite element method, response surface method and Monte Carlo method, the statistical properties and cumulative distribution functions of static frequencies and dynamic frequencies were obtained. Probability sensitivities analysis, which combined the slope of the gradient and the width of the scatter range of the random input variables, was applied to quantitatively evaluate the sensitivities of static frequencies and dynamic frequencies with respect to the random variables. The Scatter plots of structural responses with respect to the random input variables were illustrated how to adjust the values of the static frequencies and dynamic frequencies by changing input random variables.
