无叶的

Above all this scenery of perfect human life, rose dome and bell-tower, burning with white alabaster and gold: beyond dome and bell-tower the slopes of mighty hills, hoary with olive; far in the north, above a purple sea of peaks of solemn Apennine(5), the clear, sharp- cloven Carrara mountains(6) sent up their steadfast flames of marble summit into amber sky; the great sea itself, scorching with expanse of light, stretching from their feet to the Gorgonian isles(7); and over all these, ever present, near or far--seen through the leaves of vine, or imaged with all its march of clouds in the Arno's stream,(8) or set with its depth of blue close against the golden hair and burning cheek of lady and knight,-- that untroubled and sacred sky, which was to all men, in those days of innocent faith, indeed the unquestioned abode of spirits, as the earth was of men; and which opened straight through its gates of cloud and veils of dew into the awfulness of the eternal world; a heaven in which every cloud that passed was literally the chariot of an angel and every ray of its Evening and Morning streamed from the throne of God.

在这一片人世间完美无缺的景色之上，高耸着发出白雪花石膏和黄金的辉煌光芒的圆拱屋顶和钟楼，在拱顶和钟楼的后面是雄伟的山脉，山上长满了灰色的油橄榄树，遥远的北方，在威严的亚平宁山脉紫色的群峰之上，轮廓分明的卡拉拉山把永恒不变的火焰似的大理石山顶插入琥珀色的天空，光芒夺目的浩瀚大海从山脚下一直延伸到戈尔高尼群岛，而在这一切之上，无论是透过葡萄叶丛所见到的，还是阿尔诺河上伴着飘忽的云影所反映出来的，还是同贵妇人和骑士的金色头发和红润面颊相映衬的，是一片蔚蓝的天空，无远弗届，无时不在，宁静而庄严。在那信仰单纯的年月里，对所有的人来说，那苍天无容置疑地是神仙的住所，就象地球是人的住所一样。穿过云端的大门，透过露珠的纱幕，一直通向令人敬畏的永恒世界--那就是天国，在那儿朵朵飘过的云彩实际上都是天使的战车，晨曦和晚霞的每缕光芒都来自上帝的宝座。

The results showed that the inhibition of the ERK pathway in dHP resulted in anhedonia and anxiety-like behavior, and the ERK pathway inhibition in the mPFC induced anhedonia and locomotor impairment in rats.

但值得提出的是两个脑区ERK通路在对具体的抑郁行为表现的调节上存在一定的差异，如海马ERK信号阻断引起显著的焦虑行为反应而无活力水平的降低，而前额叶皮质ERK通路阻断则表现了活力降低而无焦虑行为，从而表现了一定的脑区特异性。

The results showed that the inhibition of the ERK pathway in dHP resulted in anhedonia and anxiety-like behavior, and the ERK pathway inhibition in the mPFC induced anhedonia and locomotor impairment in rats. The phosphorylation of the cyclic AMP-responsive-element-binding protein was decreased following the ERK pathway inhibition either in dHP or mPFC.

The Plant tissue raise is the plant sterile culture technology, has the totipotency theory according to the vegetable cell, the use plant body exsomatize organ (for example root, stem, leaf, stem point, flower, fruit and so on), the organization (for example cambium, epidermis, cerebral cortex, marrow department cell, endosperm and so on) or the cell (for example big spore, small spore, somatic cell and so on) as well as the protoplast, in aseptic and suitable artificial culture medium and illumination, temperature and so on under artificial condition, can induce injuries the organization, not to decide the bud, the adventitious root, finally forms the complete adult plant the discipline.

植物组织培养即植物无菌培养技术，是根据植物细胞具有全能性的理论，利用植物体离体的器官(如根、茎、叶、茎尖、花、果实等)、组织（如形成层、表皮、皮层、髓部细胞、胚乳等）或细胞（如大孢子、小孢子、体细胞等）以及原生质体，在无菌和适宜的人工培养基及光照、温度等人工条件下，能诱导出愈伤组织、不定芽、不定根，最后形成完整的植株的学科。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

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。
