1. Introduction In order to study rock damage and fragmentation during blasting, many numerical models have been developed. These efforts have varied from semi-empirical [1,2] to formulations based on shock wave physics [3,4]. Numerical modeling of blasting has been focusing on the complexity of the blasting process. This complexity requires that numerical models be developed in a highly systematic fashion in close coordination with controlled field and laboratory experimentation. This work d… 相似文献

In my paper,on the basis of the literature review related to the acquisition of topic-prominent(TP)and subject-prominent(SP)languages and the analysis of two experiments by Jin(1994)and Kong(2001),I argue that when TP learners learn SP languages such as English and SP learners learn TP languages such as Chinese,Japanese and Korean,the acquisition of subjects and objects may follow the universal sequence of [Matrix Subject]>[Matrix Object]>[Embedded Object]>[Embedded Subject].Two theoretical issues should be considered in the future investigation.They are the nature of the interface between syntactization and topicalization,and the identification of the clustering properties of topic-drop parameter.In experimental method,elicited production data and grammatical judgment data should be both collected to testify my hypothetical assumption. 相似文献

Moral education can be received from the film Beverly Hills Chihuahua.In the modern time,moral education is believed to be in the first place on all-around education in schools.Family education is the key factor that have an effect on the quality of one’s moral ed ucation.Responsibility education and gratitude education are believed to be helpful in moral education Setback education for the youth is also emphasized in our time.The environment is very important for the moral development. 相似文献

Chromatography has become the most generalmethod to carry out preparative enantiomeric separa-tions, especially for the production of pure pharma-ceuticals and pharmaceutical intermediates[1,2]. En-antiomeric separation should be carried out on chiralstationary phases (CSPs) column due to its advan-tages over other techniques of enantiomeric separationavailable. However, CSPs often have a relatively lowadsorption capacity. In the past decades, severalkinds of CSPs have been developed[3,4].… 相似文献

1 Introduction Owing to the increasing demand for high reliabilityin manyindustrial processes , much attention has beenpaid to the problem of fault detection and diagnosis(FDD) in dynamic systems over the past two decades .Fruitful results can be found in a survey paper[1]andbooks[2 ,3]. It is well known that faults in a dynamic systemcantake many forms .They can be actuator faults ,sensorfaults ,unexpected abrupt changes of some parametersor even unexpected structure changes[4 ,5].

Orthogonal method was adopted to optimize the preozonation process and to minimize the bromate formation. Factors such as contact time, pH and ammonia concentration were investigated by orthogonal experiments to understand the interaction of various operation conditions on the formation of bromate and other disinfection byproducts （DBPs）. Results showed that pH had the most significant influence on the minimization of bromate formation. The factors influencing the formation ofbromate were in order ofpH 〉 contact time 〉 ammonia concentration. For the formation of trihalomethanes （THMs） and haloacetic acids （HAAs）, however, contact time significantly influenced their formation potential. In the practical preozonation process of waterworks, it is appropriate to set preozonation contact time to be 20 min. In order to minimize the formation of bromate, pH value of the raw water should be adjusted to 6.0, and a certain concentration of ammonia could be added into the water to strengthen the minimization effect when the concentration of bromide in the raw water is higher than that in the experimental water. 相似文献

Dissolved oxygen sensor based on sol-gel matrix doped with tris(2,2’-bipyridine)ruthenium dichloride
To establish a immobilization method of oxygen sensitive dye, a dissolved oxygen sensor based on a sol-gel matrix doped with ruthenium complex ([Ru(bpy)3]2+) as the oxygen-sensitive material is reported. The results indicate that the I0 /I100 value of the [Ru(bpy)3]2+-doped in tetraethylorthosilane (TEOS) composite films are estimated to be 10.6, where I0 and I100 correspond to the detected fluorescence intensities in pure nitrogen saturated water and pure oxygen saturated water, respectively. Also, the Stern-Volmer plot shows a very good linearity at low dissolved oxygen concentrations. The response time of the composite films is 5 s upon switching from nitrogen saturated water to oxygen saturated water and 10 s from oxygen saturated water to nitrogen saturated water. The dissolved oxygen sensors based on the ruthenium complex/TEOS composite films exhibit greater sensitivity, stability and faster response time as compared to the existing ones. Furthermore, the thin films possess greatly minimized dye leaching effect. 相似文献

Virgo处女座(Aug. 23-Sept. 22)You feel like you're not getting a fair deal these days-whether it's with your parents or with your teachers. It's easy to blame[责备] others, but have you considered that you might be causing some of the drama? You probably have a good reason to feel so moody[喜怒无], so try dealing with that issue head-on[正面的] instead of taking it out on other people. They'll appreciate it and you'll feel a lot lessguilty[难受的]. 相似文献
