使不稳定

A process for reducing nitryl with unstable guanyl on para-position of benzene ring into azyl features that active metal reacts on organic acid and solvent at ordinary temp. and pressure to reduce N-(2 or 3-M, 5 or 6-M',4-nitrophenyl)-N',N'-dimethyl acetamidine into N-(2 or 3-m, 5 or 6-M', 4-aminophenyl)-N',N'-dimethyl acetamidine, where M=H,-R,-OR,-COOR (R=H, C1-C6); and M'=H,-R,-OR,-COOR (R=H, C1-C6). Its advantages include reduced by-reaction and high reducting rate up to 80%-95%.

本发明是将苯环上对位带有不稳定脒基的硝基还原为氨基的方法，采用活泼金属，如：锌或锡，与有机酸和适当的溶剂，在常温、常压下发生反应，将N－（2或3－M，5或6－M＇，4－硝基苯基）－N＇，N＇－二甲基乙脒还原为N－（2或3－M，5或6－M＇，4－氨基苯基）－N＇，N＇－二甲基乙脒，其中M＝H，－R，－OR，－COOR（R＝H，C1－C6），M＇＝H，－R，－OR，－COOR（R＝H，C1－C6），减少了副反应，使还原收率达到80％以上，最高可达95％以上，更适用于工业化生产。

Because they are rather unstable, they are notoriously tricky to isolate and describe.

极度不稳定的特性使它们很难被分离和描述。

North Korea said Sunday night that it had set off its first nuclear test, becoming the eighth country in history, and arguably the most unstable and most dangerous, to proclaim that it has joined the club of nuclear weapons states.

朝鲜宣布，星期天晚上首次核试验成功，这使其成为历史上第八位拥有核武器的国家，但同时又是最不稳定，最危险的国家。这幅照片来自朝鲜电视台。

The benefits of this reform program is to avoid the current Chinese society, legal system and the shortcomings, but has the disadvantage is to make China's capital market to re-experience "classical capital market" under the form of equity relations unstable period.

这一改革计划的好处是避免了当前我国社会，法律制度和缺点，但缺点是使中国资本市场重新体验"根据公平的关系形式的不稳定时期古典资本市场"。

If T is not continuous, even if T is a upper semicontinuous triangular norm, it is showed by examples that there exist fuzzy dynamic systems formed by eq(1), which have unstable equilibriums.

以实例说明了即使三角模T是上半连续的，也存在形如(1)的模糊离散动力系统，使其某个平衡态在Lyapunov意义下不稳定。

Finally the whole system is obtained using a proper nonlinear function based on signum functions.

首先选取合适的不稳定线性系统，利用一系列相互平行的分界面对相空间进行划分，然后通过对该线性系统进行平移变换，使新系统作用于相应的空间区域，最后利用基于符号函数的非线性函数来统一表示整个系统。

Show phenomenon is that Quad though to the police, but for the alarm input signal is weak and job instability, leading to occurrence of alarm signal that corresponds to the way the camera's image on the monitor screen although the screen instantly converted to full-screen but lost, while the image on the monitor is still not over before the alarm screen.

表现出的现象是，画面分割器虽然能报警，但出于输入的报警信号弱而工作不稳定，从而导致对应发生报警信号的那一路摄像机的图像画面在监视器上虽然瞬间转换为全屏幕画面却又丢掉，而使监视器上的图像仍为没报警之前的多画面。

Firstly, a necessary and sufficient condition for an uncertain multi-channel descriptor system to be robustly stabilizable with a specified disturbance attenuation level is derived in terms of a strict nonlinear matrix inequality.

主要考虑分散H输出反馈控制问题。推导出了使不确定多通道奇异系统能鲁棒稳定且满足一定的性能指标的充分必要条件，没有等式约束的非线性矩阵不等式条件。

This ligament, called the suspensory ligament, makes an erection sturdy. With that ligament cut, the erect penis loses its upward angle and it wobbles at the base. The lack of sturdiness can lead to injury.

这些被称为"悬吊韧带"的韧带能够使勃起更加稳固，一旦被切断，勃起的阴茎丧失了向上的角度，根部也因为不稳定而摇晃，稳固性的丧失还会带来损伤。

And he arranged the appointment of a chief operating officer to make SAP's top-heavy organisation more efficient.

而且为了使SAP不稳定的构架更高效，他安排了常务总经理的会晤。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
