Leading city figures have been concerned by a range of issues , including the treasury ' s 0 . 5 per cent stamp duty on all share transactions , yielding the government ? 2bn ( $ 3 . 5bn , ? 2 . 9bn ) a year 金融城的大人物一直对一系列问题表示担忧，包括财政部对所有股票交易征收0 . 5 %印花税的问题。这项税收每年为政府带来20亿英镑( 35亿美元)收入。
It is widely acknowledged that extensive deforestation contributed to heavy summer flooding . experts argue that china must introduce a massive afforestation program . but i doubt whether afforestation alone will solve the problem 人们普遍认为过度砍伐造成了夏季特大洪水。专家认为中国必须推行大规模的植树造林计划。但我对仅仅植树造林就能解决问题表示怀疑。
Show solicitude for the environment problem in the whole world nowadays , development of my city certainly can not give no thought to environment , sustainable paying attention to protecting the environment , ensuring that human being and the nature develops 时下在整个世界中为环境问题表示挂念,我的城市的发展无疑地不能没有把想法给环境,足以支撑的注意保护环境,确定人类和自然发展。
But graphplan has not break through the hard constrains of strip problem expression and three supposes of classical planning . so it could not express and solve planning problems which contains resources distribution and subtle information fetching 但是由于图规划尚未突破strip域问题表示及经典规划三大假设的强约束限制,所以它不能够表示、求解具有资源分配和细节信息获取的规划问题。
Whilst the impact of financial stringency on our work did cause them concerns , their demonstrated team spirit and commitment was most comforting , not to mention the many constructive suggestions they have put forth in helping the commission meet the challenges ahead 同舟共济积极承担上任后，我曾与廉署各级同事会面，他们对资源调配的问题表示关注之馀，亦表现出同舟共济的精神，并且向我提出了很多有建设性的意见。
The algorithms theory and realization of the l _ 1 - norm svm under linear and nonlinear conditions are emphatically studied . the optimization problem of l _ 1 - norm svm which adopts the l _ p - norm to measure the classification margin is analyzed . in high dimensions feature space , l _ 1 - norm svm shows better feature compression 重点研究了l _ 1范数支持向量机在线性和非线性两种情形下的算法理论和实现,分析了采用l _ p范数度量分类间隔的l _ p范数支持向量机最优化问题表示方法。
This kind of optimization methods originated in the 1950 ' s . in 1951 , an american mathematist r . bellman etc , based on the characteristics of a sort of multistage decision making problem expressed it a series of single - stage problems and proposed " the optimization principle " for the resolution of this sort of problems 这种最优化方法产生在50年代， 1951年美国数学家r . bellman等人，根据一类多阶段决策问题的特点，把多阶段决策问题表示成一系列的单阶段问题，提出了解决这一类问题的“最优化原理” 。
