But at present , many mobile banking systems only use some cryptographic algorithms as security measures , without depicting the procedure of message exchanging as a secuity protocol , needless to say how to analyze it or provide the correctness proof of it 但目前很多手机银行系统中只是简单的使用了若干密码算法作为安全措施,没有把消息交换过程抽象描述成安全协议的形式,更谈不上对其进行形式化的分析证明。
Extracting instantaneous characters of the signals is very important in signal processing . but defining instantaneous parameters of complicated signals especially of the non - linear and non - stationary ones is difficult , measuring the parameters of them is even more difficult 信号瞬时特征的提取在信号处理中具有重要的意义,然而复杂信号特别是非线性和非稳定信号真正意义上瞬时参数的定义都比较困难,更谈不上高精度测量信号的瞬时参数。
There are some helpful researches on gtb from specifically point of view nowadays , but in totally , these researches are scattered and non - systematical , even for the studies on the influents to the china ' s economy . so such a systematically research must be done by this time 但是,总的来看,这些研究都较为零星、分散,至今为止仍缺乏全面系统的阐述与探讨,更谈不上从“绿色壁垒”的角度出发对中国经济受影响的程度这一现实问题作深入具体的分析。
There are only researches about the slope loss ' s soil particle characteristics and the temporal process of hillslope agro - forestry compound system nutrient loss in the yangtze river watershed , and deficient to the mechanism and process parameters of hillslope sediment and nutrient loss of three gorges area , and there is not a preferable systematic prediction model of sediment runoff and nutrient loss also , let alone forming benefits evaluation model of hillslope harnessing measures 目前在长江流域仅有坡面流失土壤颗粒特征和坡面农林复合系统养分流失时间过程的研究报道,而对三峡库区坡面土壤泥沙及养分流失的机理及过程参数的获得尚无报道,还没有一个较系统的泥沙径流及养分流失的预测预报模型,更谈不上构成坡面治理措施的效益评价模型。
On the other hand , if an enterprise has established an effective monitoring system , but there are ill - intentioned staff who intend to collude with outsiders to circumvent the parameters and the monitoring system , then the enterprise will inevitably face losses . staff morale will also be adversely affected , not to mention the effect on the ethical culture of the enterprise 又假若企业有良好监察系统,但有职员心存不轨,甚至串通外人故意绕过规范和监察制衡机制,那么公司亦不能减少损失,而公司其他职员亦会感到士气低落,更谈不上有什么诚信文化。
Most trade associations in our country came into being with reform of government organization from top to bottom and reorganization of trade administration bureau of government . they have the color of government administration unavoidably in jurisdiction , object of service , personnel and funds , which has caused duty of the trade association to lie in managing enterprises as members , but not to serve members , let alone trade self - disciplining and coordination . and this ca n ' t meet the need after our country joined wto 由于我国的行业协会多是伴随政府机构改革自上而下产生的,由政府的各行业管理局改组而成,从行政隶属上、服务对象上、人事上、经费上不免带有以往政府行政管理的色彩,这就造成了行业协会的工作职责在于管理作为会员的企业,而非为会员服务,更谈不上行业自律和行业协调,不能适应我国加入世贸组织的需要。
After the students graduate from junior middle school , they only mast the ordinary knowledge and some of them ca n ' t even read newspapers well , still less mastering the technology of production and the knowledge of management . therefore , it is quite necessary to develop and do some research about the pattern of exbracurricular biology and scientific education for the peasants " service in the middle school in the countryside . secondly , this thesis sets forth the basis , current situation and aim about the pattern research of biology scientific education for the peasants " service 论文首先论述了在农村初中课程和教材中呈现的大一统形式,与城市学校课程及教材相差无几,缺乏地方性和特色性,由于片面追求升学率,很少涉及农村农业和农民问题,导致绝大部分学生不能成为优秀学生而白白浪费时间,造成学生不能学以致用,毕业回家时,只具备最基本的文化知识,甚至有的学生连报纸都念不下来,更谈不上掌握生产技术、管理知识,因此在国际基础教育课程改革的大背景下,发展农村初中课外生物科技教育为农服务模式的研究是完全可行和可能的,也是十分必要的。
At the beginning of the new century , if we let it develop at will , it is difficult for us to set up the friendly and cooperative companionship , which devotes itself to peace and development and faces to the 21st century , let alone realize the wish that chinese and japanese should be friends generation after generation 新世纪伊始,倘若任其发展,不但难以构建起面向21世纪的“致力于和平与发展的友好合作伙伴关系” ,更谈不上“中日两国人民世世代代友好下去”这一美好愿望的实现。
China has now become one of the worlds largest producers and consumers of many commodities such as tin , steel , coal and rice , accounting for about one third of world consumption and output . but demand - and - supply conditions on the mainland do not play a commensurate role in influencing international commodity price formation , let alone defining the rules of the game 中国现已成为全球最大的商品生产国和消费国之一,一些主要商品如锡钢材煤炭和稻米的消费量与生产量都占了世界总量的三分之一左右,但内地的供求因素对国际商品价格形成缺乏应有的影响力,更谈不上参与游戏规则的制定。
