The stereocilia of OHCs are extremely short. We can observe thephenomena of rupture and inosculation of stereocilia, which is alike senile deafness ofICR mouse. The OHCs bodies of bats have two leading characteristics. Firstly, theOHCs bodies are obviously short. The Deiters cell phalanges are of exaggerated, andthe cup formation of Deiters cell body enwrap the bottom of the OHCs.

蝙蝠耳蜗外毛细胞体，主要特征有两点：其一是细胞体明显短，三排Deiters细胞的指突明显与顶表面相连，而且毛细胞体基本被Deiters细胞的杯状膜包裹；其二是外毛细胞体在基底部呈烧瓶状，并不是一般哺乳类动物的试管样形态。

In order to get the strong convective cloud characteristics exhibiting in satellite images, about 20000 hourly gauge data of 333 surface rainfall stations and corresponding 4000 IR digital cloud images of GMS 4 during the period of 1992～1994 in Henan, Hubei and Sichuan provinces were analyzed.

对1992～1994年夏季四川、湖北、河南3省333个地面雨量站2万多个雨量观测数据以及与之相应的4千余幅GMS－4红外数字云图资料的分析结果表明，云顶温度、温度梯度、云团的膨胀、穿透性云顶的存在、云体相对于云团中心的偏离量与云的降水强度有着明显的对应关系。

Based on the ISC earthquake catalogue data, according to the orbit equations of two-body-problem and the perturbation theory of celestial mechanics, we could determine the projection pole of the sun, and thus calculate the zenith distance from the sun to the epicenter. After calculating all the earthquakes on their zenith distances, we could get the distribution of the solar zenith distance versus the occurring probability of earthquakes.

基于ISC地震记录，利用天体动力学中二体问题的轨道方程和摄动理论，确定发震时刻太阳在地面的投影点位置，并进一步计算出太阳相对震中的地心天顶距，将地震按天顶距的大小进行统计，得到地震的太阳天顶距地震频度分布。

Based on the results of underground observations and model tests of simulated materials of immediate roof, it is expounded that fragmented roof belongs in cataclastic rock mass,and its caving characteristics is clarified in this paper too.

本文根据直接顶岩体冒顶现场实测和相似模拟实验结果，阐明综采面破碎顶板的碎裂岩体属性与冒顶特征，并建立碎裂岩体冒顶力学模型，深入研究冒顶本质原因和控制原理。

After decap itation, application of exogenous either IAA or GA3 at the excised site increased garlic bolt elongation rate significantly. Again, both exogenous IAA and GA3 promoted elongation of excised garlic bolt segments. IAA showed a stronger p romotion effect than GA3 in these processes.

去顶后，在切口位置分别施用吲哚乙酸和赤霉素(GA3 )，均能提高去顶蒜薹的伸长率；外源IAA和GA3 也能促进离体蒜薹切段的伸长；在上述过程中IAA的促进作用高于GA3。

The study we have performed demonstrated that the main roof first broke with asymmetry character; gully mining-induced slope was divided into multilateral blocks by surface advance cracks. Furthermore, multilateral blocks rotated and subsided by the function of extrusion and friction between the broken rock block above the goaf and the rock mass advance the coalface.

冲沟坡体下开采时，基本顶初次破断具有不对称性；冲沟采动坡体被地表超前裂隙切割成多边块状，并在两侧坡体的夹持摩擦作用下缓慢回转下沉；相同地质条件下，坡角越大，采动坡体对工作面矿压影响越大。

With the finite element method this *** analyzes influence factors of Lateral rigidity including layout and spacing of faade bracing, horizontal bracing and unusual arrangement of faade bracing firstly, revealing the change discipline of lateral rigidity. Then, on this basis, this *** further researches on frame Stability capacity and its influence factors such as semi-rigid node, bracing spacing, base transom height, distance between top transom and the supported matter, structure height, longitudinal distance between adjacent standards, distance between adjacent transoms, horizontal load, in order to find out the law of stability capacity, guiding the design and construction.

借助有限元本文首先分析立面斜杆的布置方式、布置间距、水平斜杆以及立面斜杆不正常布置等因素对架体抗侧刚度的影响，揭示抗侧刚度的变化规律；在此基础上，进一步考查了节点半刚性、斜杆间距、底排横杆高度、顶杆伸出长度、架体高度、立杆纵距、横杆步距、水平荷载大小等对架体稳定承载力的影响，以期得到承载力的变化规律，用来更好地指导设计和施工。
