Based on the drilling operation of 4 Wells, this article describes the basic characteristic of coalbed methane and technical difficulties in drilling. Some technical keys as borehole quality, fresh Water drilling,fresh water coring, coal-bed methane protection are solved through application of a series of techno1ogical measures such as optimization of rock bit, optimization of drill stem, optimization of drilling parameters and string coring and etc. The experimental performance, especially in fine-grained ...

本文以四口井的施工为例，着重介绍了煤层气井的特点，并指出了钻煤层气井的几个技术难点，通过钻头优选，钻具优选，钻井参数优选，绳索式取心技术等的现场实施和应用，基本解决了井身质量，清水钻井，清水绳索取心，煤层气保护等几个方面的技术难题，文中还介绍了使用中原油田自行设计的中原9508绳索取心工具的取心情况，尤其是在粉煤层地区的取心情况，这将为今后的煤层气开发打下坚实的基础。

Methods The model of CHF by the intraperitoneal injection of ADR once every two days was established, The indexes of CHF through the observation of behavior, body weight, heart weight, ratio of heart weight and body weight, detection of heart function, observation of pathological changes in liver and lung under the light microscope as well as the myocardial pathological changes under the electroscope were studied.

方法采用ADR给大鼠隔日腹腔注射制作慢性心衰模型，并通过行为体征观察、初体重和终体重、心重及心体比、心功能测定、心、肝和肺病理学光镜以及心肌病理学电镜观察进行心衰指标的判定。

Methods:32 patients of TCPC were reviewed: the average age was 10 years,ranged from 5 to 24 years and the average weight was 28 kilogramme,ranged from 13 to 55 kilogramme.18 patients underwent lateral tunnel and 1 patient underwent extracardiac conduit TCPC with hypothermic cardiopulmonary bypass and heart arrest,and 10 patients were treated by extracardiac conduit technique with normothermic CPB and without heart arrest and 2 patients without CPB,and 1 patients underwent two-step operation.

回顾性分析32例全腔静脉肺动脉连接术患者的临床资料：年龄5～24岁，平均（10±5）岁，体重13～55 kg，平均（28±11） kg，病种包括单心室16例，右心室双出口并完全性心内膜垫缺损6例，完全性大动脉转位并完全性心内膜垫缺损3例，三尖瓣闭锁6例，二尖瓣闭锁1例。其中，在低温体外循环心脏停跳下18例行右房内侧隧道法，1例行心外管道法，常温体外循环心脏跳动下10例行心外管道法，非体外循环下2例行心外管道法，1例行分次全腔静脉肺动脉连接术。

However, in our community, we should not be overcritical for the moment or have too high an expectation on anyone. On the contrary, more forgiveness, compassion, toleration and concerns are needed. For those who are not good enough, we should understand and forgive them with great kindness and great compassion, and help them in different ways to move from the low over their obstacles and get rid of the cages of selfish desires.

在我们目前现状的队伍中，我们暂时还不能苛求过高，相反应当多一些包容心、慈悲心、宽容心、关怀心，对还存在差距者，多一分谅解和理解，通过我们以大慈大悲之心，用不同的方式去帮助他们，早日走出低谷，樊笼脱困。

Front-end floating pneumatic power chuck, with combined functions of self-centering clamp and floating compensation clamp, is used for machining of pipe end.

前置式气动浮动动力卡盘是集自定心夹紧和浮动补偿式夹紧二功能于一身，用于管道的端头加工，加工笔直管道时，使用自定心夹紧功能；加工的管道若有弯曲变形或加工弯管端头时，则采用定心卡盘辅助定心，用本卡盘的浮动夹紧功能夹紧管子后，退开定心卡盘再加工管子端头。

Secondly, we established the method of HPLC to determine the content of liensinine in order to control the quality of phenol total base of plumula nelumbinis. With the method we compared three different solvent extraction, and the result showed alcohol-acid water-organic solvent was the best solvent extraction.

使用HPLC法对莲子心酚性总碱中的莲心碱进行质量控制，对三种莲子心酚性总碱的提取方法进行了对比，通过三种溶剂法对莲子心总碱进行提取的实验，结果表明，醇一酸水一有机溶剂提取法提取效率最高，总碱提取率达11.25%，莲心碱提取率为1.20%，此方法操作简便，溶媒易得。
