Fictile tiles of three different shapes are first baked and then masoned into triangular irrigation pipe in ditch before the ditch is refilled.

该管道是先用粘土制成三种形状的薄片砖坯后烧制成陶砖；而后在田地里开沟，再在沟内用三种薄片砖铺砌成三角形陶管，沟内最后回填土踩实。

Firstly, full factorial experiment method is implemented to achieve an optimization of longitudinal microstructure design in the incidence plane of a LGP for LED BLUs. There are three control factors involving in the optimization process: the pitch and depth of both V-cut and U-cut, and angle and radius for V-cut and U-cut, respectively. Each individual control factor has three levels. It leads to a total of 27 sets of experiments.

本实验先行讨论全因子实验求取发光二极体背光模组之导光板入光侧纵沟微结构最佳化设计，选定入光侧V-cut纵沟微结构控制因子：V-cut角、V-cut间距、V-cut深及入光侧U-cut纵沟微结构控制因子：U-cut半径、U-cut间距、U-cut深等项目，其中各一因子分别有三个水准变化，依控制因子及其水准的目各进行27组实验。

The distances of the posterior semicircular canal and the groove of sigmoid sinus to the adjacent structures were measured. Results A.

结果 CT扫描测量乙状窦沟宽是(11.44±1.79)mm，深是(5.27±1.93)mm，乙状窦沟底到乳突外表面的距离是(10.38±3.90)mm，乙状窦沟前壁到外耳道后壁的距离是(13.66±2.18)mm。

The main results were summarized as follows: 1 After forestland was destroyed into farmland, the main erosion type changed from sheet erosion to intensive rill and severe shallow gully erosion, accelerated soil erosion was severe and erosion intensity was hundreds to thousands times greater than those in the forestland prior to deforestation.

随着开垦年限的增加，单位降雨侵蚀力引起的侵蚀量呈加剧趋势。在植被破坏15年的裸露休闲地浅沟集水区，侵蚀蚀强度随坡长的增加而增加，且浅沟槽侵蚀量大于浅沟间，切沟沟槽侵蚀量大于切沟间。

The results indicate that the main erosion type is sheet ero-sion at the beginning of the rainfalls, and serious erosion happens after rill erosion appears. Accumulated sheet and rill erosion amount increases with the rainfalls time. The percentage of sheet erosion amount decreases and rill erosion percent-age increases with time. At the end of the rainfalls, the total rill erosion amounts are 4.3 and 5 times more than sheet ero-sion.

研究结果表明，降雨初期坡面以面蚀为主，细沟出现后，坡面侵蚀将加快加剧；随着降雨时间的延续，累积面蚀量和细沟累积侵蚀量都将逐渐增加，后者的增加速率大于前者，面蚀所占总侵蚀量的百分比随降雨时间呈曲线形式逐渐递减，细沟侵蚀则逐渐增加；试验结束时细沟侵蚀量分别为面蚀量的4—5倍。

Besides, when the experimental soil was clay soil of Yangling, the appearance and developing process of rill erosion happened respectively 12-15min and 4-8min earlier than of silt soil of Shaanbei.Accumulated sheet and rill erosion amounts increased with the rainfalls time, and the latter increased quickly than the earlier. The total accumulated rill erosion amounts were 2.5 and 5.5 times more than accumulated sheet erosion amounts.

黄绵土坡面发生细沟侵蚀的时间早于粘黄土坡面12-15min；坡面细沟侵蚀达到稳定的时间粘黄土坡面也比黄绵土坡面滞后约4-8min；累积面蚀量和细沟累积侵蚀量均随降雨时间的延续而增加，且后者增加幅度明显大于前者；降雨结束时，坡面细沟累积侵蚀量约为累积面蚀量的2.5～5.5倍，约占坡面总侵蚀量的80％以上。

According to the distribution of species and amount, the author makes a PCA analysis to the different habitats. The analysis of hierarchical cluster to different habitat is according to the distribution of species. According to the results of the two ways of analysis and the factual condition of environment, the environment of Daqinggou is divided into 3 types of habitat that are described as the hygric plant community in the bottom of ditch, xerophytic plant community in the top of ditch and single type plant community.

以直翅目昆虫种类和数量的分布为属性对不同生境作PCA分析并以直翅目昆虫种类分布为属性作等级聚类分析，两种分析方法所得结果十分相似，结合分析结果和实际情况将大青沟7种不同生境分为3类，分别命名为沟底湿生植物群落，包括水曲柳植物群落、湖边湿地植物群落和稻田植物群落；沟上干早植物群落，包括沙丘草地和大果榆植物群落；单一型植物群落，包括人工针叶林植物群落和蒙古栋植物群落。

Nov. mainly inhabits those channels such as mahuang channel、gari channel、bori channel、heping channel and dengchi channel. So it belongs to the distribution area extremely narrow type. From May to October 2005 and May to August 2006, 671 specimens collected were used for studies on the reproductive strategies such as reproduction time, spawning type, the ratio and the fecundity, and gonad development and characters of early life history. The main results are as follows: 1.Every year speaking of spawning season the male"s is earlier than female"s slightly.

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
