同时发生的

In real flight, multiple sensors of aircraft engine control system may fault at a time. In order to solve this problem, a revised multiple-failure-hypothesis based testing is investigated. This approach uses multiple Kalman filters, and each of Kalman filter is designed based on a specific hypothesis for detecting specific sensors fault, and then uses WSSR (Weighted Sum of Squared Residual) to deal with Kalman filter residuals, and residual signals are compared with threshold in order to make fault detection decisions. The simulation results show that the proposed method can be used to detect multiple sensors soft failures fast and accurately.

一般认为两个以上传感器同时发生故障的概率较小，但实际上不能排除其发生的可能性；提出了一种改进的多重故障假设方法来解决航空发动机控制系统多传感器同时发生软故障的问题，这一方法采用一组卡尔曼滤波器，每个滤波器对应一个被检测传感器的故障模态；采用残差加权二乘方处理滤波残差并与门限值作比较来判断是否发生故障；仿真结果表明，所提出的方法能有效解决多传感器软故障的检测与隔离问题。

The difference of opinion arises because, where events occur in separated locations, both sets of observers have to make calculations before they can decide on the simultaneity or otherwise of separated events; they have to make allowance for the time it has taken for the light signals to travel from the distant locations, and both insist that the speed of light is a constant in all directions relative to them.

不同的观点就出现了，因为在事件发生的两个地方的两组观察者在确定事件是否同时发生之前都必须先经过计算；他们必须扣除光信号从远处传来时所耗的时间，而同时，他们又都坚信光速在相对他们的所有方向上都是恒速的。

The results are as below: 1. In Brasenia, 3 sepal primordia and 3 petal primordia initiated stimultaneously in each whorl. The first six stamen primordial initiated in a whorl stimultaneously, and the succeedings ones initiated in irregular spirals. Ascidiate carpel numerous, initiated in spirals.

结果表明： 1。莼菜的萼片和花瓣各3枚，都为轮状同时发生；雄蕊多数，除最早发生的6枚雄蕊原基为轮状同时发生外，其余均为螺旋状向心式发生；心皮多数，螺旋状向心式发生，为囊状型心皮。

The result of stress analysis shows that temperature load induced remarkable thermal stress, and under pressure and temperature load, the distribution of the stress depend on the thermal stress. The most dangerous casse is not the steady operating case, but the transient case at the moment that the shell-side fluid is just shut down, but tube side pressure load and thermal load still retain.

通过强度分析表明，温度载荷对管板造成了较大的热应力，而且在温度载荷及压力载荷共同作用的工况，热应力决定了整个管板系统的应力分布；本题研究的管板的危险工况不是发生在管程载荷、壳程载荷和温度载荷同时作用的正常操作工况下，而是发生在可能出现的壳程压力先停(管程载荷和温度载荷同时作用)的瞬态工况下。

In Nymphaea, 4 sepal primordia initiated from abaxial to adaxial side of the floral apex. Petal and stamen numerous, initiated in spirals. The apex of floral primordium caved in at the late stage.

睡莲的萼片4枚，向轴式发生；花瓣和雄蕊多数，螺旋状向心式发生；花原基的顶端在后期向下凹陷；心皮6～8枚，呈一轮同时发生，为对折型心皮。

The research shows that if the protected zone of aircraftAiis intercrossed with the shadow of aircraftAjon a horizontal surface and there is a vertical conflic,t a flight conflictbetween aircraftAiandAjwill occur. Under this condition, it is advisable to adjust the aircraftheading and speed or alter the flightaltitude to avoid the flightconflictwith the help of a surveillance radar.

研究表明：在水平投影面上，如果飞机Ai的保护区与飞机Aj的阴影交叉，将发生水平冲突；如果同时发生垂直冲突，那么飞机Ai和Aj 将发生飞行冲突，需要在雷达监控下，通过改变航向、速度和飞行高度以避免飞行冲突。
