The result showed that there was no expression in the normal control group and an apparent expression of ERK1/2 and Elk in the asthma group. A rather dense expressing of ERK1/2 was at bronchiole and mucous membrane, sub mucous membrane, smooth muscle, cytoplasm and nuclei of the out layer of the smooth muscle cell and an expression of positive fiber at submucous membrane.

结果发现正常肺内没有发现ERK1/2和Elk的表达，而哮喘时肺内有明显的ERK1/2和Elk表达，ERK1/2较密集表达在小支气管和细支气管的粘膜层、粘膜下层、平滑肌层和平滑肌外层细胞的胞浆和胞核中，也可见粘膜下层有阳性纤维表达。

The first level and the lower level both have their objective functions and constraint conditions, the objective function and constraint conditions of the first level not only have relations with the upper decision variable, but also depends on the optimal value of the lower level.

上层和下层各有目标函数和约束条件，上层问题的目标函数和约束条件，不仅与上层决策变量有关，而且还依赖于下层问题的最优解或最优值。

"On Nethery Wings" use the Nether Drake to fly up there, then keep spamming the Phase Disruptor item to keep hitting the Void Conduit, easy quest

"在下层之翼上"（使用下层蜉蝣飞到那里，然后持续运送相位爆裂物品来不断撞击虚空之泉简单的任务）

From the perspective of social mobility, middle-stratum and lower-stratum within new-diddle-stratum tend to enter into an alliance with the lower-stratum of the society while the body of this stratum-managers, technicians, and private entrepreneurs-will possible establish friendly ties with the upper-stratum of the society.

从其社会流动特征看，内部的中、下层有可能与下层结盟；而三大主干群体－经理、专业技术人员及私营企业主阶层，则有可能会与上层缔结友好关系。

At the same time, there is possible risk of declining from self stratum to lower stratum space. The story in The laborer's love is about that a huckster successfully gained his love capital to enter upper stratum. However, the story in the pear necklace is about declining from the middle stratum to the lower stratum and then returning to the middle stratum in image.

劳工之爱情》讲述的就是下层空间的小商人成功地获得向高层空间迈进的爱情资本的故事，而《一串珍珠》则是叙述了一对中产阶级夫妇由中层空间跌落，降至下层空间，后又想象性地回归到中层空间的过程。

Setting: University hospital research laboratories Subjects and Interventions: NB4 and A549 cells were separately cultured with ATRA and/or dexsamethasone for 1-3 days. NB4 or ATRA -NB4 cells were then placed in an upper insert and co-incubated with A549 cells or their conditioned medium located in a lower plate.

材料与方法：将NB4 细胞与 A549 细胞分别经有／无全反式维甲酸及 dexamethasone 处理 1-3 天，再将有／无全反式维甲酸处理过之 NB4 细胞置入嵌入式培养之上层舱，下层舱中则置放有A549 细胞或各种不同处理的条件培养液，再将上层舱嵌入下层舱中，於含 5% CO2 之培养箱中共同培养。

An understory of shorter trees and a lacework of woody vines, or lianas, produce a forest of such complex internal architecture that many animals, including some sizable ones, rarely or never descend to the ground.

下层植被和藤蔓植物形成了具有相当复杂的内部体系的森林。生长在冠层和新生树木层的树较少。由于阳光穿透冠层使下层植被和森林地表植被生长得更好。

In fact, the tango tradition, music and dance alike, was developed in both Montevideo and Buenos Aires by the lower classes3, which included European immigrants4 and descendants5 of African slaves.

事实上，探戈这项传统－－音乐及舞蹈皆然－－是由蒙特维多与布宜诺斯艾利斯两地的下层阶级所共同发展而成，而这些下层阶级包括了欧洲移民以及非洲奴隶的后裔。

During the late Qing dynasty, owing to the invasion of the western imperialists, the Qing dynasty was forced to accept the notion of nation-state, and in order to reenforce the socail control under the circumstances that little social linkage existed between the upper and lower classes, the Qing government recognized and appropriated the cultural resources of the Beijing lower class--the belief in Pi-hsia Yuan-chun and the organizations of the pilgrims so as to control the folk society.

晚清时，西方帝国主义的侵略，使清王朝被迫有了民族国家的概念，为了加强对社会的控制，在上下层社会联系渠道不多的情况下，清政府认同并篡有了北京下层民众的文化资源--妙峰山的碧霞元君信仰及其香会组织，以此来达到控制民间社会的目的。

At the end of the interval after the last container is filled, the oldest container in the solera is tapped for part of its content, which is bottled.

Solera系统通俗的讲，就是酒桶呈金字塔堆放，最新的酒在上，酒农会从最下层的桶里取出一部份(一般不超过3分之1)的酒裝瓶，再从上一层的桶内取酒补充到最下层的桶内。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
