危险状态

The fatigue is analyzed for the SENT specimen of TA6V titanium alloy at different stress ratio and on different stress level by the general finite element analysis software ANSYS. The dangerous fatigue location is predicted by the nodal stress Y-direction of the hemicycle notch for TA6V titanium alloy SENT specimen. Based on the local stress-strain method and the material S-N graph, the nominal stress-strain of the specimen is converted to the local stress-strain of the dangerous location by the elastic and plastic finite element analysis, thus the fatigue life is estimated by Miner fatigue damage accumulation theory and compared with the fatigue test of small crack growth.

借助大型通用有限元分析软件ANSYS对TA6V钛合金SENT试样在不同应力比和不同应力水平下进行疲劳分析，根据SENT试样缺口处的应力状态分布预测疲劳危险部位，采用局部应力应变法，结合材料循环的S-N曲线，通过弹塑性有限元法将构件上的名义应力谱转换成危险部位的局部应力应变谱，从而根据危险部位的局部应力应变历程采用Miner累积损伤理论对构件的疲劳寿命进行估算，并与疲劳小裂纹试验数据进行比较分析。

A oil warehouse was served under the backgroud of engneering application in this paper. Based on analyse and distinguish of oilcan fire, hazardous factors in explosion and accidental characteristics, consequently, inherent hazard scale of the oilcan section was educed by using DOW's fire explosive index method. In that way those errors between safety precaution and present criterion were also definited by analysising and calculating the effect of safty compensating coefficient in deducing hazardous scale of oilcan fire.

本论文以某油库作为工程应用背景，在对油库的火灾、爆炸危险因素及事故特点进行分析、辨识的基础上，应用道化学火灾爆炸指数评价法，对油库中最危险的油罐区进行定量评价，得出油罐区的固有危险等级，分析、计算了不同状态下安全补偿系数对降低罐区火灾危险等级的影响，明确了所采用安全措施的有效性及与现行标准规范要求尚存的差距。

More than 90% of land bordering the Mediterranean from Almeria in the south to Tarragona in the north is co idered to be at high risk.

Of course it is very discommodious. Based on previous studies of the application software to calculation on properties of smoke flow in fire Network Modeling and the time forecast software of personal evacuate travel in high-rise building, according to the quality and energy conservation principle, the paper proposes fire flue gas temperature when the fire reaching a dangerous state in the network model, then evacuation time can be calculated. Simultaneity, the paper proposes a new method that combining VB with MATLAB program technology to analyze and evaluate safety egress in Multi-layer and Multi-room building fire, besides the BF-SPES(the Building Fire Safety Performance Evaluation System)is worked out.

Some specially biological changes and mechanism of tumors need further be explored to i-dentify the patients in riskful condition for active treatment to them.

需要进一步探索肿瘤的某些特殊生物学改变和机理，确定出危险状态下的病人，以便对其进行积极治疗。

The defender must be allowed to affirm the pasties on the count.

共同危险行为人如果认为自己不应承担责任，可在以下几个方面提供证据：1、指明谁是实际致害者，或者证明其不可能具有侵害原告的危险行为或状态。2、证明原告的损害完全是由其本身的责任造成的或是由共同危险行为以外的行为造成的，即由第三方行为造成的。3、证明其具有法定的免责条件(不可抗力、正当防卫、紧急避险等)。

Vehicle turns to nonlinear behaviour of limiting condition when taking high-speed-turning, lane-change or brake-in-turn. Individual wheel's lateral stiffness rapidly decline then. Vehicle loses control response of driver and deviates from the desired trajectory, which easily leads to oversteering or understeering, especialy in low attachment icy road conditions.

当汽车的运动处在极限状况的非线性状态时，如在高速大转弯、换车道、超车、转弯刹车时，存在单独车轮的侧偏刚度迅速下降，汽车对驾驶员操纵失去应有的响应，车辆的运行状态偏离驾驶员期望的行驶状态，尤其在冰雪等低附着路面条件下，容易导致过度转向或不足转向，车辆发生危险。

Then we have analysed the HT-7U vacuum vessel dynamic response under the seventh grade seismic and transient electromagnetic load from the point of view of structure dynamics.
