A phase advancer has a main AC-AC frequency conversion circuit consisting of thyristors.When sampling circuit detects the zero passage signal produced in rotor current of motor,main circuit controlled with advanced microcomputer controlling technique will change the AC voltage of 380V,50HZ into compensating voltage with the same frequency as that of rotor voltage and rotor current 90°in phase lay to achieve the goal to raise the power factor of the motor.

由可控硅构成的交变频主电路，在采样电路检测到电机转子电流产生的过零信号后，经过先进的微机控制技术控制主电路，将380V、50HZ交流电压转换成转子频率相同，相位滞后转子电流90°的补偿电压，达到提高电动机功率因数的目的。

Downstream axially from nose apex to afterbody,a local sectional-side-force extremum always presents itself behind the forming of the corresponding shed vortex and new lee-side vortex.

沿轴向从头部尖顶往后体，截面侧向力局部极值的形成总是滞后于相应脱落涡、新生背涡的形成，截面侧向力局部极值的大小同时取决于相应脱落涡、新生背涡的形成方式和相应背涡的强度。

Airiness in the environment and a fire problem arose the attention early in the abroad, the research almost covers all the aspects. However, because of all kinds of factors, the related research on the problem lag behind in China.

国外对地铁环境中的通风及火灾问题关注的较早，着手进行研究的工作开展的也较为全面细致，但国内由于种种制约因素，在此相关问题上一直处于滞后状态。

A long time, China's bond market development lagged behind, lacking the GEM, the product is not rich, investors structure is irrational, restrictions on capital market size, level of development of varieties and the expansion of space, affecting the allocation of resources of capital markets function effectively.

长期以来，中国的债券市场发展滞后，缺乏创业板市场，产品不丰富，投资者结构不合理，资本市场规模，水平，品种的发展和空间扩展影响的资本资源的分配，限制市场有效运作。

However, during the practice of carrying the new rural cooperative medical service system, first we must solve these issues, such as: the ambiguousness of the attribute, the fuzziness of target location, the high cost and much difficulty of propaganda, the weak sense of peasants' heath care and shared risk, the weak administrative capacity of medical institutions, the worrying of doctor-patient moral standards, the lag of legislation, the low service level of designated medical institutions, the lack of operability in fund raises system and the weak responsibility consciousness of the government.

尽管我们在理论上能够阐明实施新型农村合作医疗制度的意义、试点的目标和要求、资金筹集和监管机制、医疗管理能力建设要求、完善农村卫生服务体系目标，但是在实施新型农村合作医疗制度的实践中，我们却必须要首先解决诸如属性不明确、目标定位模糊、宣传推动成本高、难度大、农民健康保健及风险共担意识淡薄、医疗机构行政管理能力较弱、对医患双方道德水准的担忧、立法工作滞后、定点医疗机构服务水平较低、筹资机制缺乏可操作性、政府责任意识不强等因素的制约。

Focusing the measurement of financial risk of extreme, this study empirically investigated the extreme risks of Chinese stock market based the theoretical researches of extreme value and relevant conclusions.This dissertation made an in-depth study on the type and nature of the asymptotic distribution of extreme value.

另外，我国正处在经济转型期，虽已初步建立起以国有商业银行为主体的商业性金融体系，但金融体制的市场改革依然远远滞后于其它经济部门，整体行业受政策影响较大，市场运行机制经常发生变化，金融体系风险非但没有降低，反而不断积聚，金融市场动荡加剧，作为市场经济晴雨表的沪深股票市场频频的巨幅涨跌即清楚地表示了金融体系的震荡状况。

The application of the Shell model to simulate autoignition of diesel fuel was stated.

计算结果表明，使用Shell模型得出的柴油滞燃期与试验测量值的相对偏差在10%以内，可以较为准确的预测柴油燃烧的着火滞后。

In the past twenty years, town and township enterprises in our country have achieved great success. But in the new situation, lack and behindhand management of talents become the bottleneck of development of the town and township enterprises.

中国的乡镇企业经过20多年的发展，取得了重大成就，但在新形势下，人才的相对匮乏和管理滞后越来越成为乡镇企业的发展的瓶径。

The development of earthworm ecology was constrained by the complex feature of soil, the scarce knowledge of natural history and biogeography of earthworms, and the low efficiency of approaches in field manipulation of earthworm community.

土壤本身的复杂性，蚯蚓自然历史和生物地理学知识的缺乏，野外控制蚯蚓群落方法的滞后等都限制了蚯蚓生态学的发展。
