For the teaching work of engineering majors in colleges and universities, engineering training is a very important practical course. In the process of engineering training, the basic course knowledge mastered by the students can be fully exercised in the process of practice, so that the level of practical skills of the students can be improved. Because in the process of practice, students themselves are willing to make bold innovations, so their innovative ability will be fully cultivated. Therefore, in the paper, the current engineering training talent training work under the background of the new engineering discipline is analyzed, and the current engineering training talent training work development situation and future work development methods are analyzed and discussed.

As an actual physical stimulation technique, seismic physical modeling technology is of great significance to actual seismic exploration. Aimed at the complicated targets of seismic exploration, the existing seismic physical simulation equipment's are difficult to meet the demand of deep and wide azimuth seismic simulation. A new type of seismic physical modeling system was designed from three aspects of physical model positioning, ultrasonic signal acquisition and physical modeling. The system can achieve high precision positioning of large-scale physical model, ultrasonic signal acquisition with multi-channel, high efficiency, high signal to noise ratio and high resolution, as well as high precision model form scanning and other functions. Combined with the specific physical model experiment, the indicators and function of the modeling system could meet the design requirements. This modeling system could provide an effective experimental platform for guiding the practical production and the study of seismic exploration theory.

Based on the seasonal river sand, laboratory test was carried out by vertical unsaturated infiltration and it studied the main factors influencing the vertical infiltration. The results show that the unsaturated infiltration can be divided into three stages changing with time. In the first stage, the infiltration rate drops rapidly. In the second stage, the infiltration rate declines slowly. And in the third stage, the infiltration rate is asymptotically stable. The initial moisture content of sample and sample texture obviously influence on infiltration characteristics. Vertical infiltration velocity decreases with the increase of initial moisture content, as the sample decreases with the increase of dry density. When the initial moisture content was 1.02% and 5.11%, the stability infiltration rate of fine sand was about 0.027 mL/(s•cm 2) and 0.021 mL/(s•cm 2). When the initial water content rate was 1.38% and 3.51%, the stability infiltration rate of medium sand was about 0.028 mL/(s•cm 2) and 0.026 mL/(s•cm 2). The initial moisture content was about 1.83% and 5.92% when the stability infiltration rate of coarse sand was about 0.030 mL/ (s•cm 2) and 0.029mL/(s•cm 2). The stability infiltration rate of the coarse sand is greater than the fine sand. The test results provide a scientific basis for the further study of seasonal river seepage law.

The network platform connecting multiple agents, which is embedded in the models to integrate individual wisdoms into a great wisdom, is called Internet of intelligences (IOI). The risk radar can be driven by IOI with mathematical models written by PHP language. A measure space of the seismic macro-anomalies group was set up in IOI based the consensus of the staffs participating earthquake monitoring and prediction. The core technology in IOI is information diffusion technology, and its intelligent development depends on the appearance of intelligent mathematics on earth. By means of the development of the factor space theory to construct IOI expressing knowledge and being cognizant of thinking, we should promote the research of "Internet + Risk Analysis" and promote the development of Web mathematics, and lay the foundation for intelligent mathematics. The IOI supported by Web mathematics is expected to decompose and dissolve wisdom ingredients in some factor spaces so that individual wisdoms are integrated to be a great wisdom.

To evaluate the effects of ciprofloxacin (CIP) residues on the microbiological characteristics of soil, the microbial biomass carbon (MBC) and carbon鄄source metabolic functions of the soil microbial communities exposed to CIP were studied by the method of chloroform fumigation extraction and Biolog technology. The results showed that the content of MBC of groups treated with CIP (w CIP 逸 0. 1滋g / g) were significantly distinguished from that of CK, and they were decreased with the increasing concentration of CIP in soil, the content of MBC in soil exposed to 100滋g / g CIP decreased 58. 69%. Moreover, the carbon鄄source metabolic functions of the soil microbial communities exposed to CIP significantly decreased, too. Under the application of CIP, the microbial utilization rate of carbon sources, including carbohydrates,
