Considering the technical requirements,the stability andthe steady performance,the quantitative requirement for sampling frequency is present indiscrete control system.Considering that there is a step delay in discrete control in grid on inverter with a Lfilter,the quantitative relationship between critical FCCR and sampling frequency isanalyzed,and the steady performance is analyzed.Considering the technical requirements,the stability and the steady performance,the quantitative requirement for samplingfrequency is present in discrete control system with a step delay.

在L型并电加热管网中，考虑到离散化控制存在滞后一拍的问题时，本文分析并获得了离散PI控制系统稳定范围时闭环根临界频率fnmax和采样频率fs之间的定量关系；针对存在滞后一拍可能引起系统稳态特性下降的问题，分析了PI控制滞后一拍对频域特性造成的影响，综合考虑并网指标、稳定性要求和离散化对稳态特性影响三个主要因素，推导了存在滞后一拍的离散化PI控制对最低采样频率的量化要求。

On either side rocks, cliffs, tree-tops, and a steep slope: forward there, the length of the boat, a tamer descent, tree-clad, with hints of pink: and then the jungly flat of the island, dense green, but drawn at the end to a pink tail.

正前方，在船身的范围之内，地形下降的坡度稍稍缓和一些，绿树将土地覆盖。有的地方露出粉红色的岩石。再过去是岛上伸展开来的平坦而浓绿的丛林，最后以一块粉红色的岩石而告终。

In a preliminary study of people with type 2 diabetes, supplementing with an extract from the leaves of Lagerstroemia speciosa for two weeks resulted in a fall in blood-glucose levels averaging 20 to 30%.

在人与2型糖尿病的初步研究，并从血液中下降的血糖水平平均20至30％，导致两个星期的大花紫薇叶提取物的补充。249的用量为32或48毫克的一产品标准化，以含有1％科罗索酸。

In this chapter, we compare the two different points of the quality economic benefits. We not only establish the econometric model from the traditional viewpoint, but also deduce the econometric model to evaluate the economic benefits of Six Sigma base on the Quality Engineering and Loss Function of Taguchi. Our research has proved that the excess cost decreased quadratically by the increasing of the sigma level.

比较了两种不同的质量经济效益观，不仅建立基于传统观的经济效益计量模型，笔者还基于田口玄一博土的质量工程学和质量损失函数建立六西格玛管理经济效益的计量模型，验证了六西格玛管理的观点，即随着西格玛水平的提高，企业的额外成本呈曲线下降的趋势。

Culms to 9 m, to 4 cm in diam., usually geniculate at basal 2 or 3 nodes of slender culms; internodes to 40 cm, initially white powdery, pubescent or scabridulous with tubercles left by fallen hairs; nodal ridge slightly more prominent than sheath scar.

秆给9米，在4厘米直径，在纤细的秆的基部的2或3 节点通常膝曲； 40厘米节间，有疣最初白色粉状，青春期或者微糙以下降的头发离开；节的脊比鞘痕突出的稍。

The statistic results showed that: Compared with the earward flow from the midtail, the nearEarth low latitude tailward flow from the ionosphere is characteristic of the lowtemperature and high density; With the tailward flow moving from the lobal region to the plasma sheet, the velocity of the tailward flow decrease, the density and the temperature increase. The tailward flow has distinct anisotropy depending on the difference of the parallel with perpendicular temperature.

对这516起尾向流的统计研究结果显示：（1）尾向流在从等离子体片边界层向等离子体片的运动过程中流速会逐渐减弱、密度逐渐增高，温度有逐渐下降的趋势；（2）对尾向流平行温度和垂直温度的分析显示不同等离子体区域的尾向流都有较明显的各向异性；（3）在从等离子体片边界层向等离子体片的运动过程中，尾向流逐渐趋向各向同性。

Topotecan is an effective agent for SCLC when used as monotherapy or in combined treatment, but myelosuppression such as leucopenia and thrombopenia was relatively severe. Although it has been recommended as a second-line agent for recurrence of sensitive SCLC, more clinical trials are needed to define its role in first-line treatment.

拓扑替康治疗小细胞肺癌有确切临床疗效，无论是单药还是与其他药物的联合用药均具有与当前一线经典方案相当的疗效，但具有相对高的致白细胞和血小板下降的骨髓毒性，已被认为是治疗化疗敏感的小细胞肺癌患者复发的二线推荐药物，但是作为一线用药仍然需要更多的实践来证实。

Thunderstorms mainly occur in summer with obvious diurnal variation. Analyses indicate that the general trend of Shandong thunderstorms has wavily reduced during the last 40 years .The interannual and decadal variabilities of thunderstorms are obvious in Shandong Province.

结果表明：山东省年雷暴日数的空间分布呈现出泰沂山区多、半岛沿海和山东西部平原较少的特点；雷暴主要发生在夏季，有明显的日变化；在过去40 a中，山东雷暴日数具有较强的年际、年代际变化，呈明显的波动下降的特点，并有一定的阶段性。

In the end of 1960's, on the reality that America was descending, Nixon Administration, facing the situation that Soviet was aggressing fully in the whole world, made a shocking decision to change the former policy of isolation and blockage and suppressing towards China and re-develop their relationship with an attitude of equality, amity and comprehension.

20世纪60年代末，尼克松政府基于美国国力下降的现实，面对苏联在全世界咄咄逼人的进攻态势，做出了一个让世界为之震惊的决定：改变以往对华孤立、封锁、遏制的政策，以平等、友好、理解的心态来重新发展与中国的关系。

We find:(1) ITB cumbers the optimization of enterprises' scale through increase the trade cost;(2) The rate of ITB on inter-industrial products is higher than on the intra-industrial aspect, and the product's trade barrier has a decreasing situation;(3) From the macro-economics view, the behaviors of governments have grave influences on the integration of domestic market; taxation system and regional law system have great impact on the many aspects which influence the development of economy.

微观方面，区际贸易壁垒通过影响企业成本控制，阻碍企业最优规模的实现，并对产业集聚的发生造成随机性影响。同时，产业间层次上的制成品贸易壁垒比重大于要素贸易壁垒，而制成品相对要素的区际贸易壁垒（无论产业间还是产业内层次）有下降的趋势。宏观方面，政府行为对于区际整合有着重要影响，财税制度和规制建设在转型经济中对地方分割等影响经济增长的众多方面造成影响。
