We explore these questions in Legume model system, Lotus japonicus. Compared with model plants Antirrhinum and Arabidopsis, floral pattern formation of Lotus japonicus is different in several aspects. Floral organs initiate in an order of sepals, carpel, petals, stamens. Within each whorl, organs initiate unidirectionally from ventral side to dorsal side. Initiation of organs in different whorl overlaps. Stamens exist in both 2nd whorl and 3rd whorl, and 2nd whorl is heterogeneous for the existence of different identity organs .

与模式植物金鱼草和拟南芥相比，豆科模式植物百脉根的花模式建成有其特殊性：一、花器官从腹部向背部单向起始；二、器官起始顺序是萼片—心皮—花瓣—雄蕊；三、不同轮的器官起始时间相互重叠；四、相同属性的器官出现在不同轮中；五、第二轮不均一，出现不同属性的花器官；六、花瓣和雄蕊不单独起始，而是经过了短暂的花瓣—雄蕊共同原基的阶段。

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。

In this study, two kinds of chemical composite single crystals , Ni〓Al and Ni〓Al+B, were grown by Bridgman method.

Ni〓Al中复杂的晶体缺陷，反常的屈服行为以及单向变形行为对晶体取向和温度的强烈依赖性，使得其在循环载荷的作用下将具有更为复杂的行为。

The algorithm performs discrete cosine transform on sub image of host image, which is cover by visible watermarking, and compresses sub image by select the set of visually important DCT coefficients. Then, the algorithm hides the compressed sub image, which is encrypted by the hash function that is constructed by Rijndael code, in the high coefficient of wavelet domain.

算法将水印图像与宿主图像进行融合，并对隐藏子图采用DCT变换，按Zig_Zag排序保留视觉重要DCT系数的方法作压缩处理，并利用Rijndael密码构造单向Hash函数作加密处理，最终分散嵌入到宿主图像的带参数的整数小波域中的高频系数，实现了可见水印的有效嵌入。

Once upon a time, I revel in other people's praise among self-considered themselves "Caigaobadou, learning-rich 5 car", so they voted pen from the text of a chapter with a cut, I hope that the works of Yin and flew to the editorial board, one by one Lost rejection with an infinite one-way I came, after many failures, multiple blows, I finally discouraged, even to the point of despair, I feel that life is too harsh to my fate for me too fair, so I complained that sink in despair to get by, wandering in tears.

曾几何时，我陶醉于别人的赞美之中，自认为自己&才高八斗，学富五车&，于是便投笔从文，一篇篇带着我切殷希望的作品向编辑部飞去，一张张带了无限失落的退稿单向我走来，在经历多次失败，多次打击之后，我终于心灰意冷，甚至到了绝望的地步，我觉得生活对我过于苛刻，命运对我太不公平，于是我在抱怨中沉沦，在失望中度日，在泪水中徘徊。

Herbert Marcuse sketches out the repressions in the modern society in his major works Eros and Civilization, Negations, One-Dimensional Man, and The Aesthetic Dimension, and sees art as the last means of liberation in a society in which freedom has become repressed.

他在《爱欲与文明》、《论解放》、《论否定》、《单向度的人》、《审美之维》等重要著作中剖析了现代社会中人性受到的种种压抑，设计了非压抑性社会的蓝图，并提出以恢复感性、诉诸艺术审美为解放人性的途径。
