Numerous impermeable underground structures exist in urban seepage field. Since the corner of the structure is singular point and the dimension of the structure is negligibly small compared with the whole urban seepage field, it is difficult to model seepage field in urban area with existing methods.

城区渗流场中地下阻水结构物众多，由于结构物角点为奇异点，而且结构物的尺寸跟整个渗流场的尺寸相比起来非常小，这导致现有的计算方法难以对城区渗流场进行模拟分析。

The surface heat processing man method has the flame hardening and induction heating the heat treatment, the commonly used heat source has oxyacetylene or flame, the induced current, the laser and the electron beam and so on oxygen propane and so on.

objective to investigate the paregoric effects of butorphanol when the errhysis occurs inside the epidural catheter during continuous epidural anesthesia.methods 60 cases of kidney stones received elective surgery.during this surgery they underwent continuous epidural anesthesia and eight cases of them showed the errhysis in the epidural catheter.then epidural injection of butorphanol was given for analgesia and hr,map,spo2 as well as muscle relaxation conditions were monitored before and 5,10,20 min after injection.the conscious and breathing of patients were also monitored.results before and 5,10,20 min after injection of butorphanol,hr and map difference were not statistically significant.the analgesic results were satisfactory.conclusion butorphanol has a definite analgesic effect when the errhysis occurs in epidural catheter during continuous epidural anesthesia.

目的 探讨在连续硬膜外麻醉中，硬膜外导管内渗血时，应用布托啡诺镇痛的效果。方法择期行肾结石手术患者60例，行连续硬膜外麻醉，其中8例硬膜外导管内渗血，均经硬膜外腔注入布托啡诺镇痛，分别监测注入前及注入后5 、10 、20 min，hr、map、spo2及肌肉松驰情况，同时监测患者神志及呼吸情况。结果注射布托啡诺前及注射后5、10、20 min，hr、map差异无统计学意义，镇痛效果满意。结论在连续硬膜外麻醉中硬膜外导管渗血时，注入布托啡诺维持麻醉镇痛效果明确。

The infiltration experiments of fixed water head and variable water head within the ring permeameter are conducted in the indoor trough. The observation data are used to optimize soil hydraulic parameters, such as horizontal and vertical hydraulic conductivities.

The research analysed the current status and pollution treatment research review from municipal refuse output, waste physical component, hazards, heavy metal pollution. On the basis of overall understand of current treatment situation about main municipal refuse landfill site of Fujian province. By the simulated test, utilizing 7 kinds of physical adsorbents (zeolite, incineration ashes, slag, plant ash, charcoal, ochre, active carbon), 4 kinds of chemical flocculant FeSO_4, AlCl_3, FeCl_3, Al_2(SO_4_3, and 3 kinds of hyclrophytes, we carried through the pollution removing study of heavy metal in landfill leachate and discussed removing effect of different physical adsorbents, chemical flocculant and hyclrophytes.

并在对福建省主要城市生活垃圾的处理现状全面了解基础上，通过室内模拟试验，分别利用7种物理吸附剂(沸石、焚烧灰、炉灰、草木灰、木炭、赭石、活性炭)、4种化学絮凝剂FeSO_4、AlCl_3、FeCl_3、 Al_2(SO_4_3和3种水生植物进行垃圾渗滤液中重金属的污染去除研究，比较不同物理吸附剂、化学絮凝剂和水生植物对垃圾渗滤液重金属污染的去除效果，试图从中筛选出治理成本低和治理效果好的城市垃圾渗滤液重金属污染修复技术，供南方城市垃圾处理场推广应用。

The result indicated that, in the different dry-wet ratio situation, the best removing effect infiltration medium was the regolith, the next was the coal ash, and the finally was the sand.

结果表明：在不同干湿比的情况下，去除效果最好的渗滤介质为表层土，其次是煤灰，最后是沙子；其去除效果的好坏相对应的干湿比依次为23：1、10：1、4：1；对于废水的进水浓度，在相同的情况下，进水浓度越高，其去除氨氮的效果越好；渗滤介质越高的渗滤系统去除效果越好。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
