It is the most powerful means of eradicating schistosomiasis. Current method of elimination cercaria is mainly the chemical method which has many disadvantages such as drug resistance, drug dilutedness, environmental pollution and poisoning the other biology, etc. For these reasons, this paper poposed a new method of elimination through high-voltage pulsed electric field, discussed the feasibility of the new method, studied the elimination mechanisms of using different forms of electrodes, analyzed various factors which influences the effect of elimination and introduced the structure of high-voltage pulsed electric field system at the stage of laboratory. Moreover, this paper showed the security problems that should be considered during the research and experiment.

针对常用的化学药物杀灭法存在的易使尾蚴产生抗药性、水域宽广致使药效降低、污染环境、毒杀其它生物等弊端，本文提出了一种利用高压脉冲电场杀灭血吸虫尾蚴的新方法，探讨了这种电子杀灭方法的可行性，分别研究了采用锐形电极和平板电极的血吸虫尾蚴杀灭机理，分析了影响尾蚴杀灭效果的各种因素，介绍了实验阶段血吸虫尾蚴高压脉冲电场杀灭系统的构成，指出了系统研制和试验过程中需要充分考虑的安全性问题。

New data of structural styles and geochronometry in the Dulong-Song Chay metamorphic dome indicate at least two epoches of major extensional tectonics: the D, deformation of the rising and exhumation of the dome occurred at 237-228 Ma; and the D2 deformation overprinted and re-deformed on the dome at 86-78 Ma. Of them, the D, deformation shows a consistent forming time, extensional direction and tectonic regime amongst the Dulong-Song Chay dome, South China block and the north margin of the South China Sea basin.

对位于华南地块西南缘的都龙－Song Chay变质穹隆体的研究表明，在中生代至新生代时期，至少经历了2期重要的伸展构造：D1期(237~228 Ma)穹隆的隆升与表露阶段，代表了印支期造山作用前的伸展构造；D2期(86~78 Ma)叠加和改造阶段，并有可能始于176~146 Ma，致使穹隆进一步隆升和表露。D2期构造在发育时间、伸展方向及变形方式等上既与华南地块同时期区域伸展构造特征相一致，也与南海盆地北缘早期扩张特征相一致。

Greenhouse effect Increased retention of heat energy by the Earth's atmosphere as a result of increased emissions of carbon-based and other heat absorbing gases, including chlorofluorocarbon and carbon dioxide.

温室效应由于不断增加的碳基和其他吸热气体的排放，包括氟氯烃和二氧化碳，致使滞留在地球大气中的热能不断增加。

Calcium and phosphorus, is the formation of the skeleton of "construction materials", the lack of new bone formation can lead to obstacles, bone Liang small, osteoporosis, soft, causing the skull to soften, according to the kind of bombs have table tennis sexy, it means that a "ping-pong head "; At the same time, the accumulation of osteoid tissue, the amount will be led to the child appears at the top of the skull circular symmetry sudden, the head thus become square, commonly known as transcranial side, naturally lose their sense of beauty.

钙与磷，是形成骨骼的"建筑材料"，缺乏可导致新骨形成障碍，骨梁细小，骨质疏松、变软，造成颅骨软化，按之有乒乓球样的弹性感，谓之"乒乓头"；同时骨样组织堆积，亦会致使孩子额顶部出现对称性颅骨圆突，头颅因而变得方方正正，俗称方颅，自然失去美感。

As a result of rapid development of city's industrialization in Shanghai whereas the lag of industrial and domestic sewage's disposal and the building progess of city's cloaca,most of rivers was polluted badly.

由于上海市工业化和城市化的迅速发展，雨污分流与污水处理的建设和发展相对滞后，致使大量工业废水和生活污水直接排入河道，河道水质严重恶化。

as a result of rapid development of city's industrialization in shanghai whereas the lag of industrial and domestic sewage's disposal and the building progess of city's cloaca,most of rivers was polluted badly.there are diversiform measures including biotechnologics for improving the water quality in shanghai.in this paper,the biotechnologic repairing's basic theory,effect,history,and application in the current world is expatiated.furthermore,a project sample which was put into practice in minghang district showed the feasibility and the actual effect of such technology in shanghai's water quality repairing.

由于上海市工业化和城市化的迅速发展，雨污分流与污水处理的建设和发展相对滞后，致使大量工业废水和生活污水直接排入河道，河道水质严重恶化。为改善上海河道水质，人们采取了多种措施，其中就包括采用生物技术修复河道水质的措施。本文浅要介绍了采用生物技术修复河道水质的原理、效果以及这种技术的发展简史、在国际上的应用现状，并以闵行区已经开展的邱泾河原位生物修复工程为例说明这种技术在上海市水质修复应用的可行性和实际效果。
