UDZ Series liquid level indicator of flap disassembly fast and convenient, the installation position can be arbitrary choice, free to change the direction of observation, thus instrumented great visibility; UDZ series of cost-effective liquid level was significantly higher than that used multiple sets of glass plate liquid level of cost performance; UDZ series of liquid level indicator, the sender's device, as well as the liquid level with the main transmission medium within the complete separation of the measured structural design, so that level gauge in the job has pressure (up to 320KG), toxic and inflammable conditions, with absolute safety and reliability; UDZ-3 type uses innovative design, improve the sensitivity of the sensor, and its near-zero drift FarEasTone signals and long-term stability so that it has always been at the scene consistent level instructions; sensors and the main body has a certain interval, which can be solved effectively under high-temperature liquids (up to 480 ) remote detection and control; antifrost type UDZ Series Level Gauge, are I plant the patented product (Patent No.: ZL00221022 3), guarantees that the use of cryogenic liquid level gauge is not freezing (such as liquid CO2), the effective guarantee of the level of a normal job.

UDZ系列液位计的翻板指示器拆装快捷方便，安装方位可任意选择，观察方向可随意改动，因而仪表指示的可视度很大；UDZ系列液位计的性能价格比明显高于采用多组玻璃板式液位计的性能价格比；UDZ系列液位计的指示器，发讯器、以及液位变送均与主体内被测介质完全隔离的结构设计，使液位计工作在有压（可达320KG）、有毒和易燃的工况下，具有绝对的安全性和可靠性；UDZ-3型采用了新颖设计，提高了传感器的灵敏度，其远传信号近乎零温漂和长期稳定性使其始终于现场液位指示保持一致；传感器和主体有一定的间隔，因而能有效地解决高温液体（可达480℃）远距离检测和控制；防霜型UDZ系列液位计，是我厂的专利产品（专利号：ZL00221022·3），保证了在低温液体上使用液位计不结冰（如液体CO2），有效的保证了液位计的正常工作。

CAN bus has been the most promising fieldbus and it has been widely used in many areas, but with the increasing of complicacy in automation systems for industrial controlling, people have more and more strict requirement to the real-time capability of information, So it is very important to study the real-time characteristic of CAN protocol for surmounting the limitation of aptotic priority in CAN protocol by taking effective measures and improving the real-time characteristic of communication system based on CAN bus.

CAN总线是目前最有前途的现场总线之一，它已经在多个领域得到了广泛的应用，然而随着工业控制自动化系统复杂性的增加，对信息实时性的要求越来越高，因此，研究CAN协议的实时性问题，采取合理的措施克服CAN协议中固定优先级机制的缺陷，提高CAN总线通讯系统的实时性具有重要的应用价值。

This paper , pertaining to a certain project situated in karstic region where geologic formation is highly developed with features of calciferous cave faults abundant, in corporation with on site measurement and anti-analysis results, sets up a geo-mechanics model for various rock formations, and by way of 3D non-linear large deformation values modelling computation, numeric simulated study was taken for different shotcreted anchoring supports upon which one has studied surrounding rock control technique under unfavourable geologic conditions.
