On the foundation of making deep investigations in the current medium - sized rvte of hubei , the author have pointed out the leading problems and deficiencies existing in medium - sized rvte of hubei at present . mainly showing in the following aspects : enrollment drops , it is difficult for the rvte to enroll new student ' s ; the funds are put into insufficiently , the condition for running a school is bad , teaching is of low quality ; the overall arrangement of the education structure is unreasonable , the area of the system is developed unevenly ; professional structure and course offered do n ' t meet the needs of rural economy development in new century ; the training objective is unreasonable and indifferent for the agricultural service , the content of courses is outmoded , the teaching form is single , and the link breaks away from the real agricultural production ; rural vocation education mechanism is not flexible , the ability is not cogent that run a school towards the society , . the efficiency in school management is not high 作者在深入调查研究湖北省农村中等职业技术教育现状的基础上，指出了当前我国农村职业技术教育存在的主要问题和不足之处，这些问题和不足之处突出地表现在：招生人数下跌、农村中等职业学校出现了招生难；经费投入不足，办学条件差，教学质量不高；结构布局不合理，区域发展不平衡；在专业结构及课程设置上不适应新世纪农村经济发展的需要；培养目标定位不合理，教学内容陈旧，教学形式单一，教学环节脱离农业生产实际，为农服务能力不强；农村职校教育机制不灵活，面向社会办学力度不大，办学效益不高，办学活力不强。
Something not humandeathis forcing the door open , and he must hold it to . he clutches at the door with a last straining effortto shut it is impossible , at least to hold itbut his efforts are feeble and awkward ; and , under the pressure of that awful thing , the door opens and shuts again 某种非人之物死亡已快破门而入，应该把门顶住才对，他够着门了，鼓起最后的力气关门已不可能了哪怕就顶住它但他的力气微弱，而且不灵活，因而在可怕之物推挤下，房门被打开，但是又关上了。
With the extending and development of mcus " applications in fields of industrial control , electronic equipments , military meters , information applications and many kinds of intellective equipments , the typical 8 - bit mcu represented by mcs - 51 emerges some limitations , such as low frequency and low working efficiency . to overcome these handicaps , a new type of 8 - bit mcu core suitable for embedded applications has been introduced in this thesis 随着工业控制、仪器仪表、军工电子、信息电器和各种智能化设备中微控制器应用的扩展与深化，以mcs - 51为代表的传统八位微控制器显示出一定的局限性，如频率低、处理效率不高、外部配置不灵活等。
This master degree thesis , based on the observing of developing actuality of on - site electrical apparatus monitoring technology , aims at overcoming the problems existing in former on - site monitoring system , such as unable to realize multiple channels sampling and hold , unable to carry out multiple channel programmable magnification , unable to monitor frequency , low pick up bits , external rom low speed data saving , inefficient data query method , inflexible debugging and installation , low precision etc . by introducing eda ( electrical design automation ) technology , we put forward a creative circuit design scheme , which can considerable updated the on - site monitor system 本文根据电气设备绝缘在线监测技术的发展现状，针对以往在线监测数据采集系统存在的集成度低，不能实现多通路并行采样，不能实现多通道同时程控放大，不能进行同步频率监测，采样位数较低，采用外部存储器方式，对数据进行查询的访问方式，安装调试不灵活等缺点，提出了应用现代微电子技术电子设计自动化( eda )技术实现对在线监测数据采集系统的改进。
Aiming at the function and performance limitations of traditional special cnc or current pc - based open - structure cnc , a brand - new cnc platform designing scheme of multi - layer open - architecture is presented , based on embedded - mcu calculation and management core , and three kinds of expanding mode of software , hardware and interface . by using double system working ram and boot rom technology , an independent re - development interface is set on the hardware platform to realize customized function ’ s simulations and verifications online , which makes all the expanding or re - configuring on basic cnc platform are all safe and restorable 本文针对传统专用数控系统的结构封闭、交互形式不通用和配置扩展不灵活方面的劣势以及当前pc模式开放结构数控的体积庞大、开放程度不高和实时可靠性不强的局限，创新性地提出了以基本cnc框架+软件、硬件和接口三种扩展形式为特征的层次化开放结构的嵌入式cnc硬件平台，并采用双存储区技术进行了cnc系统在线仿真校验机制和安全保护机制的方案设计。
Traditional distributed real - time systems must custom - tailor subtly for operation on special platform . although these custom - tailored systems provide necessary qualification for real - time application , they created an unskillful architecture with some drawback include not easily modification , update and integrated with the third part components 传统的分布式实时系统必须经过精心定制以便能在专用平台上操作，虽然这些定制的系统为实时应用的操作提供了所需的条件，但是它们创建了一个不灵活的结构，存在不容易修改、升级和与第三方产品集成的缺点。
The teaching both parties that fuzzy training system of nerve can overcome former training inside communicates the way intention for not smooth , teaching organizing with managing the ineffective and live etc . weakness , can comprehending the student , and guide the student to there is point ground in the study to proceed to offend pass , and increase train efficiency 神经模糊培训系统可以克服以往培训中的教学双方沟通渠道不畅、教学组织和管理不灵活等缺点，能够理解学员的意图，引导学员在学习中有重点地进行攻关，提高培训效率。
In the third part , great importance is attached to the inadaptability between secondary vocational education and industrial restructuring , which reflects in the following aspects : single training objective ; inappropriate course design ; out - dated auricular system ; old teaching approaches and methods ; single evaluating mode ; fossilized teaching system ; weak foundation for combination between schools and enterprises ; inadaptability between teaching staff and industrial structure 第三部分着重分析了黔江中等职业学校教育与工业结构调整的不相适应性，主要表现在：培养目标单一；专业设置不合理；课程体系陈旧；教学手段和方法滞后；评价方式单一；教学体制不灵活；培养途径单一，校企联合薄弱；教师队伍结构与工业结构不适应。
Currently , china ' s production of a common valve leakage , which leak , visual quality is not high , short life , and not flexible operating valves and electrical devices such as pneumatic devices unreliable shortcomings of some products , only the equivalent of the early 1980s , the international standard 目前我国企业生产的各种阀门普遍存在着外漏、内漏、外观质量不高、寿命短、操作不灵活以及阀门电动装置和气动装置不可靠等缺点，部分产品只相当于上世纪80年代初的国际水平。
