滞后的

Based on an analysis of the natural, social and economic situations of flood plain in lower reach of Yellow River as well as the status of harnessing, this paper elaborates the problems facing the area, such as flood menace, serious status of suspended river, severe disasters of drought and waterlog, single production structure, implementation of flood plain policies and sluggish safety construction of flood plain.

在敍述黄河下游滩区白然情况、社会经济情况、滩区治理现状的基础上，详细论述了黄河下游滩区存在的问题。由於黄河水沙问题复杂，治理难度大，滩区治理开发也受到限制，目前存在的主要问题是：l洪水威胁依然存在；2悬河形势严峻、河势尚未有效控制；3滩区旱涝灾害严重；4滩区产业结构单一；5滩区政策落实不到位；6滩区安全建设状况严重滞后。

The conventional back-EMF zero crossing method was restricted by hardware and control method,and to improve the detecting circuit reduce the influence.

常规反电势过零检测电路由于受到硬件及控制方法的影响，过零点信息不够准确而且有较大的滞后，通过对检测电路的改进来减小这种影响。

In the MTD models,the contributions of different lags upon the present are considered separately and combined additively.

混合转移分布模型，又称高阶可和马尔可夫链，简单来说，就是高阶马尔可夫链的不同滞后对目前时刻的影响是可分并且可和的。

The drum water level is an important variable to be controlled, it is hard to get the mathematic model of the water level with adjustive process, it is characteristic of nonlinearity, instability and time lag.

而模糊控制不要求知道被控对象的精确数学模型，只需要操作人员的经验知识及操作数据，鲁棒性强，非常适合用于非线性、滞后系统的控制。

Bryozoa is an important group of metazoan animals which has received relatively little attention regarding their origin, phylogenetic relationship with other metazoan phyla and its internal phylogeny.

苔藓动物是后生动物中的一个重要类群。然而，和其它主要后生动物类群相比，长期以来对它的系统学研究却相对滞后。其起源、系统发生地位以及与其它后生动物门类之间、其内部各高级分类群间的谱系发生关系一直存在争议。

The experimental results indicated that under the steady operating conditions, the ignition timing of the base fuel (PRF90-90% iso-octane+10% n- heptane), which is equivalent to RON 90, delayed and the peak value of the heat release rate was low compared to the base fuel with single additive (Ditert-butyl peroxide-DTBP, Dicumyl peroxide-DCP, Tert-butyl hydroperoxide-TBHP, Tert-butyl cumyl peroxide -TBCP or Cumene hydroperoxide-CPO) which advanced ignition timing and increased the peak of the heat release rate obviously.

试验结果分析表明，在HCCI发动机燃烧稳定工况下，没有添加剂的基础燃料记作PRF90(为90%异辛烷与10%正庚烷的混合，相当于90号汽油)着火滞后，燃烧放热率峰值低，而混有单一添加剂(Ditert-butyl peroxide-DTBP、Dicumyl peroxide-DCP、Tert-butyl hydroperoxide-TBHP、Tert-butyl cumyl peroxide-TBCP或Cumene hydroperoxide-CPO)的基础燃料则着火明显提前，燃烧放热峰值升高。

In spite of this, China's economy continues to be driven by the "strong horses" of trade and investment, with what the local press dubs the "weak donkey" of consumption lagging behind.

尽管如此，中国经济增长的推动力，仍然来自于贸易和投资这两匹强壮的&马&，而中国媒体冠以&瘦驴&称号的消费则滞后。

However, at the present time, the development of domestic 3PL companies is lagged behind. Most 3PL companies are middle of small sized ones. Theyre small in size and many in quantity lacking of modern logistics theories and not forming core competitiveness. The logistics market falls short of effective supply which can be seen from the price competitiveness of low levels between logistics companies and the low quality of logistics supply. The companies fall short of motivation of epibolic logistics and the market falls short of demand.

但目前我国第三方物流的发展相对滞后，第三方物流企业大多为中小企业，规模小、数量多，缺乏现代物流理念，尚未形成核心竞争力，物流市场有效供给不足，具体表现为物流企业间低层次价格竞争，物流供应质量不高；企业缺乏物流外包的动力，物流市场的需求不旺。

So research on theory of Identification, reforcement and reconstruction is exigently required.

论文结合工作实际，通过参与四川省展览馆加固改造工程的质量监督，首先了解混凝土加固结构的受力特点，分析了新旧混凝土共同工作问题和应力滞后现象，同时重点介绍喷射混凝土加固技术的发展现状。

The process of implementing project existed various kinds of problems, such as the big funding gap, the imperfect supporting policies, the shortage scientific and technical guidance, the foresty bother, the imperfect project management,the stortage understanging of the police, the pressureof surplus labor and the lagging follow-up industrial development and so on. For the sake of the sustaint development of the project, Guarantee System of the Conversion of Cropland to Forest is found.

同时总结了该工程在实施过程中存在的问题，主要有资金缺口比较大、配套政策不完善、缺乏科技指导、存在林权纠纷、工程管理不完善、对政策认识存在误区、剩余劳动力压力大、后续产业发展滞后等，这些问题制约着工程持续有效的推进及其成果的巩固。
