The results showed that the initial temperature of methanation is different for the carbonaceous phases with different stability.

研究结果表明，不同稳定性的碳相在氢气氛下的起始甲烷化温度是不一样的，构成碳纳米管主体的六元环的碳，较之类似活性碳的杂形碳以及主要由五元环和七元环构成的碳纳米小颗粒，在氢气氛下是较为稳定的。

It is of instructive significance to the design of robust controller when the closed-loop gain shaping algorithm is used to decide the magnitude of the model perturbation.

为了给出闭环增益成形算法的模型摄动形式，用小增益理论和H 混合灵敏度算法的结果进行推导，发现闭环增益成形算法的模型摄动形式与灵敏度函数的形式相同，该结论对用闭环增益成形算法设计鲁棒控制器时系统所能忍受的模型摄动大小的确定具有指导意义。

The dried materials after the de-watering will go up with the heat-air flow. The step rings will stop and keep the big particles. Small particles will be discharged out of the drier from the ring center and will be restored by the whirl separator and dust remover. The not-fully-dried or big piece materials will be sent to the wall of the equipment by centrifugal force function and be smashed again after they fall down to the bottom.

脱水后的干物料随热气流上升，分级环将大颗粒截留，小颗粒从环中心排出干燥器外，由旋风分离器和除尘器回收，未干透或大块物料受离心力作用甩向器壁，重新落到底部被粉碎干燥。

A fishing float or cork.In the centre of the ring is a red cross, at the circumference holes for the pegs.

木环中央有个红色十字架，木环的周边有许多小孔，以便把小木橛子插进去。

Simulation results show that the performance of the open-loop control system is poor when the model parameters change. The second system is designed via feedback linearization method. Since the path signal is introduced as feedback signal, the designed closed-loop control system improves the system robustness to the parameter perturbation. Simulation results verify that the closed-loop control system shows better performance than the time optimal control system.

前者侧重于时间最短的控制性能，但由于是开环控制，当出现参数摄动时，系统的性能会受到较大影响；后者由于引入了飞艇轨迹的反馈信号，因而相对提高了系统对参数摄动的鲁棒性，计算量较小，并且仿真结果证实了这种闭环系统设计方案可以抑制参数摄动带来的影响，与时间最优开环控制系统相比，显著提高了控制精度、改善了控制效果。

Scan lining, and create checks in gauze, double plastic at the excess moisture is absorbed ring lining will result in a change (because fiber paper water absorption or pre-polymer, the paper fiber will change in radial), and smaller variation, so that the ring extension thefibers radial lining.

扫衬时，往往在纱布处施以倍胶，过多的水分被环衬吸收后将导致纤维发生变化(因为纸张吸水或失水后，纸张纤维将在径向发生变化)，而纵向变化较小，使环衬沿纤维径向延展。

The associated findings such as fluid accumulation surrounding the rotator cuff or in synovial sheath of biceps long head and chip fracture of greater tuberosity were helpful for diagnosis.

其他附属发现如肽二头肌长头滑膜鞘及旋转环膜附近积水对旋转环膜撕裂之诊断亦相当有帮助，伴隨的发现如肽骨大结节小断裂偶亦可由超音波侦测出。

At first, we give the more precisely expression of the system in some sufficiently small neighborhood of the saddle point under some suitable transformation, and use the foundational solutions of the linear variational equation of the unperturbed system along the homoclinic or heteroclinic orbits as the demanded local coordinate system.

首先，我们在鞍点的充分小邻域内给出系统在适当的变换下的更加精确的表达形式，利用未扰系统沿同宿，异宿环的线性变分方程的基本解组作为系统在同宿，异宿环的小管状邻域内的新的局部坐标系。

These hairline cracks sometimes develop over time in high-strength aluminum alloy and may reduce carabiner strength by more than 50%.

使用时检查钩环的开口附近是否有损坏，这些小破损有时候会出现在高强度的铝合金上，可能使钩环的强度降低50%，有裂缝或明显损坏的钩环应该丢弃。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
