时控的

It is shown that under the supervision of the monitoring functions, the switching of control signal will stop after a finite number of switching and the tracking error will converge to a residual set that can be made arbitrarily small by choosing some design parameters sufficiently small.

进而证明，当被控对象相对阶大于1、高频增益符号未知时，在监控函数的监测下，相关控制信号经至多有限次切换后将停止切换，跟踪误差将收敛到一个残集内，且该残集可通过减小某些设计参数而变得任意小。

When grond handling in strong winds, have an assistant on your leeward side to help you if you lose control of your wing.

当在强风中控伞时，你需要有一个助手在你顺风的侧边，你失去对伞的控制时他可以帮助你。

The guards of the city were at that time under the charge of Gaius Maecenas, of equestrian rank, but none the less of illustrious lineage, a man who was literally sleepless when occasion demanded, and quick to foresee what was to be done and skilful in doing it, but when any relaxation was allowed him from business cares would almost outdo a woman in giving himself up to indolence and soft luxury.

当时罗马的守备部队由出身骑士等级的盖乌斯·玛塞纳斯掌控。他的血统却很高贵，他在形势需要时可以非常警惕，迅速地预见出下一步该采取的行动并熟练地执行之；但当可以脱开公务消遣之时，其沉迷奢华温柔怠惰懒散几乎又超过了妇人。

The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

方法回顾性分析200例行适应性前瞻性心电门控双源CT冠状动脉血管成像的患者(排除扫描过程中，屏气配合差，出现心律不齐的患者及行支架置入或搭桥术后复查的患者)，包括屏气时平均HR≤75 bpm患者122例，HR≥91 bpm患者78例；其中30例同期行选择性冠状动脉血管造影，按屏气时HR将其分为2组，A组17例：HR≤75 bpm，B组13例：HR≥91 bpm，分别与金标准SCAG对照，计算2组患者的阳性诊断准确率，应用SPSS 13.0统计学软件，利用Kappa检验比较每组患者的2种诊断方法诊断结果的一致性，利用两样本率x~2检验，比较2个心率组间的诊断准确率有无明显统计学差异，并计算此30例患者的平均有效辐射剂量。

In terms of payload, stealthiness, power and transmission, it's already superior to the other helicopters like tiger and A-129 that are in the market. And once the MMW FCR is developed and placed on top of the rotor, I really can't think of what other helicopters have that it doesn't. Remember, Apache didn't get the MMW radar until Longbow.

在有效载荷、隐身、动力与传输系统方面，它要比市场上的其他直升机，如虎式、A129性能更好，而且一旦毫米波射控雷达研发完毕，安装在旋翼上部时，我确实想象不出还有同类型的直升机，阿帕奇是知道发展到长弓型号时才具备的，但这可不便宜。

When you delete a file, the service simply requires the virtual path to the file you wish to delete; I store this virtual path in a SubItem of the ListItem object when populating the ListView control, so all I do here is read that value out and send it back to the file service.

当您删除文件时，只需要服务的虚拟路径的文件要删除，我在一个商店的ListItem时填充ListView控件对象，分项目，这个虚拟路径，因此，所有我做的，是读出来的价值其发回的文件服务。

The methods for calculating the diameter of safety pin, fit clearance between the sleeve and hole in the planetary gear, and the quantity of the lubricants filled in the gear mechanism are presented.

供料系统根据钻井液密度的变化对钻井液流量的控制，电控系统在启动和停机时的程序控制，以及停机时的自动冲洗，都将直接影响整机的使用性能。

Through processes: increasing humidity by spraying--controlling humidity by air exchange--spraying occasionally, it can not only eliminate cohesions, contraction and the hardness of fiber, but also greatly improve the skin softness, the surface grain and the appearance.

经过喷雾加湿—控湿排湿—时喷时停等流程后的皮革，可消除纤维黏结、缩曲和硬性，减小部位差，对提高丰满度、柔软度、粒面纹路更清晰，外表感观等必将产生极佳效果。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
