Results show that amplitude of displacement excited by vertical incidence wave is larger than that excited by inclined incidence wave and not influenced greatly by the incidence angle. In vertical incidence, amplitudes of displacement of two points at the same altitude along each cavern are basically identical and maximum relative displacement occurs between top and bottom point of the cavern. While in the case of inclined incidence, displacement amplitude on sides meeting the wave is larger than that on leed sides, and maximum relative displacement occurs on left skewback and bottom of the cavern.

结果表明，位移幅值受入射角度的影响不敏感，竖直入射比斜入射情况要大；竖直入射时，各洞室两侧同一高程处的位移幅值基本相同，相对位移差最大部位为洞顶与洞底，而斜入射时迎波面比背波面一侧位移大，且相对位移差最大部位为洞室迎波面的左拱座与洞底。

RESULTS : The hypertrophic cardiomyocyte NTPase Vmax values at 1 week group and 4 week group were all increased significantly in both of ATP and GTP as substrates with much higher argumental extent in early hyper group; their Km values were kept constant in early hyper group and were decreased only in late hyper groups.

结果：早、晚期肥大组心肌细胞核被膜NTPase最大反应速率以ATP为底物时较对照组增加25%～62%(P＜0.01)，以GTP为底物时增加8%～44%(P＜0.01)，其中晚期肥大组NTPase最大反应速率增加幅度低于早期组。早期肥大组细胞核被膜NTPase Km值不变，晚期组NTPase Km值下降，以ATP和GTP为底物时晚期肥大组Km值分别下降22%和86%。

The result showed that:(1) There were a higher density of Ostreidae and Balanidae and a lower biodiversity in the cay sampling section of Daxie Island.(2) No significant difference was found in the macrozoobenthos community among the tide plat sampling section in Daxie Island.(3) There was a lower macrozoobenthos species number, biodiversity, and a higher density of Sternaspis scutata and Capitella capitata than those in the sea area beside Daxie Island. Moreover, a significant difference was found in the macrozoobenthos community between the sea area of Daxie Island and the adjacent islands.

结果发现：(1)大榭岛岩相潮间带断面牡蛎科和藤壶科等科的物种栖息密度较高，生物多样性较低；(2)泥沙相潮间带底栖动物状况与其他海岛差别不显著；(3)大榭岛近岸海域底栖动物种数少于其他海岛近岸海域，且前者不倒翁虫和小头虫等多毛类物种栖息密度较高，生物多样性较低，群落结构与其他区域相差较大；(4)环境质量的生物评价结果显示，大榭岛近岸海域扰动程度高于其他海岛近岸海域。

By making theoretical analysis on vibration characteristics of a single slab and multi ones set in the inverted arch ring, four processes about stability failure, that is free vibration, locking, sleeking and distortion are proposed on the condition that water sealing was damaged and anchor-hold was out of action, a formula of the slab's maximum free displacement and dynamic equations in each process are obtained.

对反拱水垫塘单底板块和多底板块振动特性进行了理论分析，提出了拱圈底板块失稳分为自由振动、锁定、滑动变形及拱圈失稳四个过程，给出了各振动过程的动力学方程以及底板块自由振动的最大理论高度的计算公式。

As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.

对于同一断面，靠近槽底的测点气泡个数分布最大值出现在气泡尺寸小于1mm的范围内，朝水面方向各测点气泡个数分布最大值呈减小趋势，而其对应尺寸则呈现变大趋势；在靠近槽底，个数分布表现得比较集中，而在水面附近气泡个数分布曲线表现得低而平缓；实验条件下，整个断面上的气泡个数分布的最大值大体上出现在尺寸为0.5mm的地方；气泡平均尺寸在槽底处接近于0而朝水面方向迅速增大，且越接近掺气水流的水面，增加速度越快，最终趋于无穷大；气泡总数在掺气发展区内是沿程增加的，当掺气水流发展到一定程度后气泡总数就基本保持不变了；在同一断面上，各测点单位时间内的气泡总数随高度呈现出先增加后减小的趋势。

The company now has sea-farming area with ownership of 600,000 mu and fulfills 400,000 mu bottom-sowing of scallops, 10,000 mu bottom-sowing of sea cucumber, 1,500 mu bottom-sowing of abalone and 150,000 mu botton-sowing of ark shell; it becomes the largest scallop cultivation base of the country and explores the largest sea area independently in home.
