The kinetics of reconstitution of apoacylase with either 〓 or 〓 and the inactivation of the 〓 reconstituted enzyme by 1, 10-phenanthroline has been studied by following the substrate reaction continuously in presence of the metal ion or OP respectively. Although the native 〓-containing and the 〓-reconstituted enzymes have closely similar Michaelis constants and maximal velocities, the kinetics for both the inactivation by OP and the reconstitution of the apoenzyme with the metal ions differs considerably.

虽然钴重组的氨基酰化酶与天然含锌的氨基酰化酶在催化活性上比较相近，但两种酶在去金属失活动力学机制以及去金属失活的氨基酰化酶与两种金属离子重组复活的动力学过程均存在较大的差异，说明锌在氨基酰化酶中的作用比较复杂，并不能完全由钴替代。

The kinetic approach of the substrate reaction during modification of enzyme activity has been applied to a study on the kinetics of the course of inactivation of metal enzyme by metal ion chelator and reactivation of apo-enzyme by metal ion restoration.

I call this maneuver CTRL-ALT-DEL or reset. There are two buttons at the bottom of your harness, and you have to push them simultaneously to reset your glider. Whenever your glider is cravatted, and you can't get it out by picking some lines or collapsing half the wing, you use a full stall to solve the problem (but of course only if you have enough height). Sometimes a glider keeps flying great with a cravat, so if you can land it there's no need to full stall.

可以把这个动作类比为CTRL-ALT-DEL即是热启动；这里有两个&摁钮&在吊袋下面，你必须两手同时摁着你就可以将你的伞&重起&了；任何时候你进入卷夹，只要你有高度，你就可以使用全失速改出；当然，有时候卷夹并不是特别影响你的飞行，你也没有必要一定使用全失速改出，去着陆即可

The following exciting results are derived: 1 When considering the influence of some nonlinear elements such as hard-limit of exciters, the effects of some devices such as Power System Stabilizer, Unified Power Flow Controller and Static Var Compensator as well as using real parameter values of power systems in simulation , the SNB surface and the HB surface on the boundary of small signal stability region will turn close to each other and even coalesce together; 2 Under some conditions, coupling between slow exciters and shunt capacitors will bring negative damping in power system dynamics, which increases the possibility of oscillatory instability, so that a power system with mass shunt compensators is easily subjected to the oscillatory instability.

同时发现：1 系统中的慢速励磁，在某些情况下会与并联补偿电容器组产生负阻尼现象而显著降低系统的动态性能，大大增加系统出现振荡失稳的可能性；2 在采用较多并联电容器组补偿的电力系统中，更容易出现振荡型失稳。

In fact, the process of fuel breakup and atomization is a kind of instability phenomenon of the liquid jet. In order to increasing the oil surface area and promoting efficient combustion, the instability process of the jet is always used to make the fuel atomization in engineering.

燃油的分裂与雾化过程实际上是液体射流的一种失稳现象，在工程上常常利用射流的这种失稳过程来实现燃油的雾化，以增加燃油的表面积提高燃烧效率。

A cusp catastrophe model is presented to describe the behavior of sliding along one deep incompetent structural plane of a gravity dam foundation, and the sufficient conditions leading to instability are discussed. It is found that the instability of sliding relies mainly on the stiffness ratio k, the homogeneity index of the medium m and the geometry-mechanic parameter ξ and that the reliability of the traditional limit analysis method is deficient.
