结果表明，青山组第一旋回中偏碱性富钾火山岩的形成年龄为10 9.9± 0 。6Ma ，第二旋回酸性流纹质火山岩形成年龄为 10 8.2± 0 。6Ma ，据此确定胶莱盆地青山组火山岩应为早白垩世岩浆活动的产物。

Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

流纹质岩石总体具富碱、富硅、富铝，贫钙、贫镁特征，其Rb、Th等元素的含量较高，而Ba、Sr、Ti、P等元素含量则明显偏低，并具显著的铕负异常（εEu=0.16'0.44），岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。

Results In three Hank's solution infused cochleas, the thresholds of IC potential were kept in the normal level and no hair cell loss was found 14 days after the beginning of the infusion, suggested that the pump implantation and Hank's solution infusion had no significant effects on the cochlear functions. In contrast, threshold shifts of IC potentials and hair cell loss were found in two BSO infused animals, suggested that the infused solution had distributed into the whole cochlea.

结果 应用渗透压泵耳蜗灌流Hank液后，下丘电位阈值维持正常，耳蜗毛细胞无损伤；灌流BSO液14天后，所测频率(1、 2、 4和8 kHz)的下丘电位阈值平均升高28 dB，内耳毛细胞平均缺失39.3%，缺失分布于耳蜗各回，表明渗透压泵工作良好。

On gelatin-coated surface, cells were more resistant to shear flow compared to those on tissue culture polystyrene or biocompatible polyurethane. The newly grown cells on the gelatin substrate after flushing for a period of time became further resistant to shear flow.

与组织培养盘之聚苯乙烯或生物相容性之聚碳酸酯型聚胺酯这两种材料相比，在涂布有明胶的基材上，细胞具有较佳之抵抗流场剪应力之能力，而且，其后新长回之细胞，较原先之细胞，更能抵抗流场的进一步冲刷。

For each strategy, a corresponding exploitation plan of groundwater was designed. Then each designed exploitation plan (except scheme 3) was put into the model for calculation and simulation. The analysis on the forecasting results every plan indicates that:(1) Shuting down the self-provided wells is the most direct and effective method, playing an important role in the land subsidence prevention.(2) The resumption of compressed soil by groundwater artificial recharge is limited. So the artificial recharge can\'t provide essential effect for the resumption of land subsidence, unless the artificial recharge is much more than the groundwater withdrawal.(3) The method of "adjusting the exploitation stratum of groundwater to the shallow" has an obvious effect on the land subsidence prevention.(4)"Sand wells" can increase the leakage recharge for confined aquifer, and thus can slow and prevent the development of the land subsidence.(5) For the groundwater exploitation in Xi\'an, emergency self-provided wells should be managed according to the well spacing of 1600m, 2000m and 1600m, respectively, in the river terrace area, alluvial-proluvial fan area and loess tableland area to exploit the first confined groundwater. Corresponding individual well yield can be set as 2500m~3/d, 1500 m~3/d and 200 m~3/d. Make emergency self-provided wells pump in the dry year and stop pumping groundwater to restore and conserve underground water sources in average years and wet years. In this way, groundwater withdrawal of 162000m~3/d can be obtained to provide for the supplement of water supply in Xi\'an. As a result, the water supply stress can be released in dry years. The groundwater depression formed in the exploiting year can resume in 3-4 years. At the same time, this exploitation manner will not lead to obvious land subsidence.

本文利用所建的模型预测了现状开采条件下未来20年的地下水位和地面沉降的变化，在此基础上，提出了防治西安市地面沉降的五个地下水开采方案，利用所建的地面沉降模型对各个设计方案其进行了模拟和预报，对预测结果的分析表明：①封停自备井是防治地面沉降最为直接和最有效的对策，对防治地面沉降起着最为积极的作用；②采用人工回灌方法使被压缩的土层得到的恢复是非常有限的，对地面沉降不能起到根治作用，只有回灌量明显大于开采量时才能有一定的效果；③&调整开采层次，在浅层取水&对防治地面沉降的效果十分明显；④布设&砂井&可以增加对承压含水层的越流补给量，从而可以有效地缓解和控制地面沉降的发生和发展；⑤对西安市的地下水开采，可在河流阶地区、冲洪积扇区和黄土塬区分别采用1600m、2000m、1600m的井间距布置应急自备井，分别采用2500m~3/d、1500 m~3/d和200 m~3/d的单井开采量，开采第一承压水，在平水年或者丰水年不开采，涵养地下水源，在枯水年启动这些应急自备井开采，在输出分析范围内共可获得162000 m~3/d(5913万m~3/a)开采量，可以有效地补充西安市的供水水源，缓解供水紧张局面，开采年开采导致的下降的水位可在停采3～4年后得到基本恢复，同时，这种开采方式不会造成大的地面沉降量。

In 1961, I was sent to Cuba to Bahia de Cochinos. It was part of a CIA-sponsored invasion under the guise of taking Cuban exiles back to their country. But the US government betrayed them. Our weak-kneed President held back their air support. Defenseless, the exiles were annihilated by the Cuban army.
