Great achievements have been attained presently on the shallow natural gas exploration in mud diapir zone on the base of the regularity of gas migration and accumulation controlled by the upward-intrusion of thermal fluid.

根据泥底辟热流体上侵活动控制天然气运聚成藏的地质规律，目前已在泥底辟带浅层天然气勘探中取得了很大的成功，迄今为止在盆地所获的天然气地质储量主要源于浅层勘探领域。

However, during borehole grouting pile construction of the present, round section piles are used universally. Generally speaking, the boreholes are drilled by a large diameter round piling bit. Because of the restriction of factors of the mud pumps, and drilling equipments, and drilling technique, it would result in such problems as fol lowing: a bigger cutting area and overlarge cuttings volume, and more hole bottom sediments, difficult cuttings discharging, and serverely repeat cuttings breaking, and using more concret grouting amount, and lower drilling speed, faster bit wearing, and longer working period, bigger material and labor ex haust, and higher engineering cost, unreasonable ratio of loading capacity to volume of pile foundation, and lower comprehensive economic benefits, and so forth.

然而，钻孔灌注桩施工中，目前最为普遍采用的是圆形断面桩基，一般采用大口径圆形基桩工程钻头，由于国内生产的泥浆泵、钻具及钻进方法等因素的限制，从而使钻孔破岩面积和体积过大，造成孔底沉渣过多，排渣困难且排浆量大，重复破碎问题突出，混凝土灌注量大，直接反映为钻进效率低、钻头磨损快、施工工期长、材料能耗和劳动消耗大、工程成本较高、桩基荷载能力与体积比不合理、综合经济效益不理想等，这些问题严重影响和制约着钻孔灌注桩施工技术的发展和进步。

The results are: 1 the stricture of the capillaries of stria vascularis was observed in most cochleae of rickety rats and, segmental deletions of the outer hair cells on the first turn of cochlea were found in a small number of rickety rats; 2 the perilymphatic ionized calcium concentration significantly re- duced and the threshold of CAP (Compound Action Poten- tials of the eighth nerve) significantly rose in rickety rats in comparison with those of normal control; 3 gentamicin results in an increase of the perilymphatic ionized calcium concentra- tion in rickety rats; 4 the cochleae of the rickety rats appeared to be less vulnerable to the ototoxicity of gentamicin than the normal one.

研究包括两个方面，其一是&佝偻病的感觉神经性耳聋及其对庆大霉素耳毒性作用的耐受性&，系用大白鼠建立维生素D缺乏性佝偻病动物模型，发现：（1）佝偻病大白鼠耳蜗血管纹毛细血管狭窄，少数动物耳蜗底回外毛细胞有节段性缺失；（2）佝偻病大白鼠的耳蜗鼓阶外淋巴钙离子浓度降低，CAP（听神经复合动作电位，以下简称CAP）听阈提高；（3）庆大霉素可使佝偻病大白鼠耳蜗外淋巴钙离子浓度上升；（4）佝偻病大白鼠耳蜗在功能和形态上都比正常者更能耐受庆大霉素的耳毒性损害。

The results showed that the free-living marine nematodes were the dominant group the percentage of which in the total number of meiofauna ranging betwean 76.1%~96.3%. The abundance of meiofauna in old mangrove district was the least and in bare beach where waste water flows was the most. There were a total of 37 putative species in the samples. The total number of recorded species was the lowest in the new mangrove district, and highest in the old mangrove district. The species diversity indexes, species evenness indexes and richness indexes in old mangrove district were all higher than those in new mangrove district. The dominant species and feeding types were different in three types of habitats.

结果表明：海洋线虫是凤林红树林中小型底栖动物中的绝对优势类群，占到小型底栖动物的76.1%~96.3%；从丰度来看，旧区白骨壤林中小型底栖动物的数量较少，有污水流过的光滩数量较大；4个断面共鉴定出海洋线虫37种，其中新区秋茄林中的生物多样性指数较低，旧区白骨壤林中群落具有较高的物种多样性；从出现的物种来看，新区秋茄林、旧区白骨壤林和光滩上出现的优势种和摄食功能群的类型各不相同。

坐落在伊拉克最大油田上的底比斯镇中有一座很大的原油泵站，库尔德人因而也绝不可能取消底比斯镇周边的防御工事。

The research employed nylon bag implantation and in vitro fermentation techniques. With the procession of in vitro fermentation, anaerobic fungal population density in the cultures were shown to increase, with the largest fungal populations growing on ryegrass leaves, ryegrass stem and straw occurring after 48 h of incubation.

结果表明，随体外发酵的进行，真菌数量逐渐增加，以黑麦草叶、黑麦草茎、稻草秸为底物时，瘤胃真菌数量均在48 h达到最大值，且真菌数量的最大值随底物木质素含量的上升呈下降趋势。
