The results indicate that the different thermal expansions and elastoplastic properties and distributed randomness of various mineral particles composed of oil shale will lead to the nonuniformity of thermal field , deformation field and stress field in heating process , which makes the particles of oil shale deform incompatibly : and the release of product pyrolysis results in irreversible damages of oil shale material and structure . These are the main reasons for the thermal fracture of oil shale .

研究结果表明：组成油页岩各种矿物颗粒热膨胀和弹塑性性质的不同及其分布的随机性，导致油页岩加热过程中温度场，变形场和应力场的非均匀性，使得油页岩颗粒间变形不协调和油页岩热解产物释放引起油页岩材料与结构性能发生不可逆的劣化损伤，这是油页岩发生热破裂的主要原因；热传导方式加热油页岩，温度的传递比较缓慢，加热井和生产井的间距不宜过大，对油页岩储层性质存在差异时，注热井应选择较高热导率的区段；油页岩的层理对油页岩地下原位开发形成渗透带至关重要，油页岩达到热解温度会产生附加的膨胀力，首先在层理处开裂，应充分利用油页岩层理赋存条件改造其渗透性。

The results indicate that the different thermal expansions and elastoplastic properties and distributed randomness of various mineral particles composed of oil shale will lead to the nonuniformity of thermal field, deformation field and stress field in heating process, which makes the particles of oil shale deform incompatibly: and the release of product pyrolysis results in irreversible damages of oil shale material and structure. These are the main reasons for the thermal fracture of oil shale. When oil shale is heated through thermal conduction, temperature transfers slowly, so the spacing between heating well and production well should not be kept too long. When difference exists in oil shale reservoir's properties, heating well should be chosen in the high conductivity region. Oil shale's stratification is vital for developing permeation zone in in-situ retorting. Oil shale will generate additional expansion force as it reaches its pyrolysis temperature, and stratification will be cracked first, so the oil shale stratification should be utilized to enhance its permeability.

鉴于国内突发污染事故的不断增多而相应监测方法尚未完善的当前状况，为充分发挥气相色谱-质谱联用在定性、定量中的优势，在讨论气相色谱-质谱联用在水体、大气、土壤三类有机污染事故中的应急监测方法，并针对不同的污染物情况提出了相关的前处理方法、条件程序。

Since, according to this definition, lying is always a free communication between fully responsible and rational persons, and because, according to those who defend this definition, it is indefeasibly "impermissible for anybody, in conditions of free communication between responsible persons, to express an opinion he does not hold" Donagan 1977, 88; cf.

由于根据这个定义，撒谎一定是具有充分责任和理智的人们之间的一种自由交流，而且因为，根据那些捍卫这个定义的人们的观点，&不允许任何人，在按照负责的人们之间自由交流的条件下，表达一个他没有持有的观点&(Donagan 1977， 88； cf。 1986)这是无可辩驳的。

It finds that under the dual economic structure, the relatively low development degree of the modern industry and the detention of the mass labourhood in the countryside have led to the shortness of the land resouce per capita, the waste of the country laborhood, and the restriction of the growth of peasants'income.

勾画了二元经济结构制约农民收入增长的机制，指出由于二元经济结构条件下现代工业发展程度较低，大量劳动力滞留在农村，造成人均土地资源较少，农村劳动力得不到充分利用，制约农民农业经营收入增长。

The problems of robust stability and robust stabilization for interval systems were discussed. A necessary and sufficient condition for the robust stability of a line segment polynomial was proposed. The tested results of robust stability of a polynomial polytope and robust stabilization of an interval system were obtained in terms of the condition.
