Or you should be made any annular plastic bracket to input any small switch on door cover.

或者你司可以制造一些环形的，或者是有环纹的塑料支架，去输入一些小的开关在门套上。

It is shown that the closed-loop system is globally uniformly ultimately bounded with respect to a compact set around the origin. This set can be made arbitrarily small by increasing the gradient of the saturation function.

其结果表明，闭环系统关于原点的一个紧集是整体一致最终有界的，并且该紧集可以由增加饱和函数的斜率而做得任意小。

Under an infinite-horizon risksensitive cost criterion, the controller designed can guarantee an arbitrary small longterm average cost for arbitrary risk-sensitivity parameter and achieve boundedness in probability for the closed-loop system using the integrator backstepping methodology.

在无限时区风险灵敏度指标下，应用积分反推技术，设计了控制器。所设计的控制器能够保障对任意风险灵敏度系数具有任意小的指标，并且闭环系统为概率意义下有界的。

Because the uncertainty of this class of system is bounded by a linear function of the norm of the delayed states with unknown bounds, an adaptive update law is proposed to estimate the square of these unknown bounds.

论证了鲁棒自适应控制器存在的条件，并给出了能适应未知参数变化且使得最终闭环系统状态一致最终有界的鲁棒控制律的设计方法。

CRP/CAP Catabolite activator protein,CAP is an activator required for high level transcription of the lac operon.The active molecule is a CRP dimer that binds 3'5' cyclic AMP to form a CRP-cAMP complex.

CRP/CAP 分解代谢物激活蛋白CAP是Lac操纵子高水平转录的一个必须的激活因子，有活性的CRP二聚体与3ˊ5ˊ-环式AMP结合形成CRP-cAMP复合物。

It is a contact and complaisant seal, which allows the sealing surface radial fluctuating in certain amount.

它由多个带"指"的圆环片、前后挡板和隔片组成，是一种接触式柔性的封严结构，能允许封严面有一定的径向跳动。

If two nondiffracting beams with small difference of convergence angle and common axis exist at same time, they will interference with each other to form a light field structure that varies periodically along the propagation direction. It is a new kind of space distribution of light beam.

如果两束汇聚角略有不同的同轴无衍射光同时存在，则它们相互之间叠加干涉后产生一种纵向呈周期变化的光场结构，这是一种新的光束空间分布，这种光束在横向仍是一种同心环光斑，可用于精密对准。

The main features of the frame include:① Software testing,evaluation and development are explained in a cybernetic context.

该框架的特点主要有3个：①将软件测试、评价与开发视为一个闭环的控制过程，在控制语境下约束软件测评之间的含义。

Stem loops and short dyad sequences appear in the downstream of the translation stop codon.

序列结构分析发现在编码区的下游有可形成茎环的反向重复序列和形成发夹结构的回文序列。

One day we were traveling from the city of Galway toward the Ring of Kerry.

有一天，我们正在从向凯瑞的环的 Galway 市旅行。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
