不实用的

Different from previously presented threshold RSA signature schemes, this new scheme can effectively avoid computation of any element\'s inverse in any algebraic structure such as Z_(φ and Z_N, which makes the complicated algebraic extension, parameter constraint and inversion pre-computation all unnecessary.

该体制基于整数矩阵运算，不需要对任何非域代数结构中的元素求逆，为构造高效实用的门限RSA签名方案奠定了基础。

On the other hand, this paper proposes a practical method to solve the problem of inconsistency of the optimized results,to which is led under two or more earthquake waves inputted.

此外 ，还提出了一种实用的方法，解决在多条地震波输入下消能支撑参数优化结果不一致的问题

The trace gas concentration was measured by the above method, for example,1～70 parts per million by volume of hydrogen, or acetylene or ethene, or 50～550 parts per million of carbon monoxide.

计算结果表明，单一网络的泛化能力较强，但识别准确度在某些值处达不到实用的要求。

From the view of design, there are mainly three solutions to depress this vibration: the first way is to enhance the collectivity stiffness of platform, it will make the structures heaver, that is to say, it can't meet the economic demand;the second way is to implement active control, however, it is difficult to be carry into execution and unable to decrease the expensive cost.

降低平台的冰致振动响应大致有三个途径：一是提高平台结构的总体刚度，这样做显然会使平台加重而不满足经济性要求；二是对平台结构的冰致振动进行主动控制，但是此种方案在恶劣的海洋环境中很难实施并且不会降低海洋平台的总体成本；三是对平台结构进行减振和隔振控制，相对来说，此种方案是行之有效并且经济实用的。

-- China's draft recycling law has abandoned a progression price markup system on household use of water, electricity and gas because of its impracticality.

因为不断上涨的物价，如水、电、气的拥有不实用。

This method is not influenced by the connection and initial condition and the method is effective and applied.

该方法不受接线方式和初始条件的影响，具有快速、实用的特点。

There is no way it can be thought of as a function of a certain way of thinking or conceptualizing: it is a basic fact, in the sense of being unavoidable in a more than pragmatic way, and it could not be thus basic if the physicalist ontology were correct.

没有可以视为"思或概念化的特定方式的结果"的方式：在不可避免地不是实用的方式上是一个基础事实，而如果物理主义者的存有学是正确的，那么就不会如此基础。

In order to develop an useful synthestic process, we have synthesized amides with various substitutents. The isoquinoline skeleton was constructed through Bischler-Napieralski reaction, followed by asymmetric reduction of the imine intermediates with a Ru complex to form the only chiral center. Finally, we connected the two phenyl groups by Heck reaction and effectively obtained optically active aporphine alkaloids.

为了发展一套实用的合成方法，我们首先制备於苯环上具有不同种取代基的苯乙醯胺，接著透过Bischler-Napieralski反应进行分子内合环，并利用钌金属对亚胺中间体进行不对称的还原反应，建立出产物中唯一的光学活性中心，最后再利用Heck反应连结两个苯环，就可以顺利得到具有光学选择性的阿朴吩类天然物。

His suggestion is as good as a play, but it is not practical.

他的建议很有趣，但是不实用。

The internal motivation of this longing did not spring from a utilitarian purpose, nor did it from an impulse of excitement-happy "movement" or "ideological trend", but from a hating-to-be-neglected spirit of creation.

令人感动——当然并不令实利主义者感动——的是，当展览通知一发出，仍然有许多艺术家表示渴望参加展览，这种渴望的内在动力并不是来自实用的心理，也不是源于富于刺激性的&运动&或&思潮&冲动，而是生发于不甘寂寞的创造精神，这是完全不以由作品本身来证实的。
