People are required to know and analyze the operating axes of rotary kiln in time in practice, in order to adjust and maintenance it in reason. So The Great Wall Aluminum Corporation of China bankrolled for studying the microcomputer real-time monitoring system of large-scale rotary kiln and commissioned Central South University to develop it.Based on analyzing and comparing the status quo of the monitoring system of rotary kiln, this paper brings forward a new method of monitoring the operating status of rotary kiln. It analyses the system-error and the configuration and demonstrate the feasibility in detail. In the design of hardware configuration it analyzes the principle and speciality of the tailor-made eddy current transducer and PCI-1713 analog input card and the multilevel supervisory network.

With this method, we had several important differences compared to the YDmodel. First, the ratio of daily increment of PDT and the deficit of both water and nitrogen was used to estimate the effect of environment. Second, a nonlinear function was adopted to describe vernalization and thermal effectiveness (instead of three-stage linear function). Third, sinusoidal function was used to describe photoperiod curve cluster for different cultivars.

According to structural characteristics of floating slab tracks, a track segment element was taken between two adjacent fasteners. For each element, rails were regarded as Euler beams supported by discrete viscoelastic supports. The fasteners and rubber supports were replaced by a linear spring and damp. So the vibration model of the floating slab track was established. In constructing vibration model of a metro train, each car of the metro train with two suspensions was modeled as a multi-rigid body system, in which rigid bodies were connected with each other by a linear spring and damp. Combining the potential energy of vertical vibration of the track with that of the metro train, the total potential energy of vertical vibration of the train and track was obtained. And then, the matrix equation of vertical vibration of the system was established using the principle of total potential energy with stationary value in elastic system dynamics and the "set-in-right-position" rule for formulating system matrices. The vibration responses of the system can be obtained by solving the matrix equation with the direct time integration such as Wilson-θ method.

A series combined test method tests were performed to determine the liquid-plastic limits of different samples of fine grained soil and silty sand. The result showed that the loglog relationship between the depth of penetration of fall cone and the water content of some samples were clearly not linear, and the liquid-plastic limit could not be obtained according to the linear relation. Effective test data could not be measured within the three arranges of water contents proposed by the present standards. The dependability was necessary to discuss about the liquid-plastic limit test results obtained from three arranges.

采用液、塑限联合测定法针对部分细粒土和粉砂进行液、塑限测定时，发现对于部分细粒土在双对数坐标上圆锥下沉深度与含水率之间的关系并非线性关系，无法依据线性关系确定液、塑限：采用规程建议的三个含水率范围有时根本无法获得有效试验数据；采用规程建议的三个含水率范围确定得到土的液、塑限试验结果的可靠性有待商榷；采用直线段试验数据确定的液、塑限进行分类可能出现相互矛盾甚至错误的结果。
