必要条件

Due to these factors, knowledge in each quale is organized around prototype and has internal structure in gradation.

这三部分特质结构并不是构成概念内容的一组充足必要条件。

We first introduced a new concept called transitive resolvable idempotent symmetric quasigroup, proved that the necessary condition for the existence of TRISQ is also sufficient, then presented a tripling construction for LKTS by using TRISQ instead of TKTS, thus removed the condition "there exists a TKTS" in Denniston''s tripling construction for LKTS; We also improved J. Lei''s product construction for LKTS by removing the condition "there exists a TKTS".

我们首先引入了可迁可分解幂等对称拟群的新概念，证明了TRISQ存在的必要条件也是充分的，然后给出了用TRISQ取代可迁Kirkamns三元系的LKTS的三倍构造法，这样就去掉了在Denniston的关于LKTS的3倍构造中的条件"存在一个TKTS"；我们用TRISQ取代TKTS改进了雷建国的关于LKTS的一个积构造方法，从而去掉了该构造方法中的条件"存在一个TKTS"。

It is shown that a fuzzy subset of a BCI algebra is an FSI ideal if and only if it is both an FSC ideal and a fuzzy BCI positive implicative ideal.2. A new class of quotient BCK/BCI algebras and a new class of bounded quotient BCK algebra are constructed, respectively. By investigating their applications, it is shown that these quotient structures are more reasonable than ever before and possess good properties.

构造了一类新的商BCK／BCI代数和一类新的有界商BCK代数，利用这种构造，各类型商BCK／BCI代数可以被相应的Fuzzy理想／滤子完全刻画，以往的商构造被Fuzzy理想／滤子刻画时只有充分条件而没有必要条件，因此新构造弥补了以往构造的不足，比以往的构造更加合理。

Secondly, the problem of linear prediction for Qy in the original model and its transformed model is considered, the notion of linear sufficiency and the problem of comparison of linear models with respect to prediction problems are proposed and the corresponding necessary and sufficient conditions for the transformation to be linearly sufficient and for one model to be superior over another are given, respectively.

其次，我们讨论了原始模型和变换模型下Qy的线性预测问题，提出了在该预测问题意义下的线性充分性和模型比较的概念，分别给出了变换Fy是线性充分的、以及一个模型优于另一个模型的充分必要条件，此外还得出了一些特殊结论。

Introduced is a kind of space uniform rational spline curve, which possesses tension parameters and is based on hyperbolic spline functions.

引入了基于双曲样条函数的、具有张力参数的空间有理等距节点样条参数曲线，给出了这种曲线在每个样条子区间上为挠曲线段的充分必要条件；分析了这种挠曲线段没有尖点、重结点和泛拐点的特性；因而在用于空间曲线几何造型时可避免奇异性。

According to the first and second references, a sufficiency and necessity condition on rational root of integral coefficients polynomial is put forward and a reduced method of testing the rational root is also shown in this paper.

摘要给出了整系数多项式有理根的一个必要条件，从而得到整系数多项式有理根检验的一个简化方法，达到了简化整系数多项式有理根检验的目的。

To the real McCoy, they feel that training is something essential to increase employee's productivity, and these institutions strongly encourage managers to plan and schedule employees to obtain the necessary training. Whereas for the followers (this may include some local banks and financial institutions), their attitude towards training is something akin to perks and benefits, where employees are perceived to gain more than the employers.

真正的顶尖金融公司认为培训是提高员工生产力的必要条件，因此这类公司鼓励经理们策划组织员工进行培训；而级别较低的金融机构则将培训看作对员工的福利，他们认为员工从中得到的好处要大于公司得到的。

The langu age is, indeed, more difficult of acquirement in the one case than in the other, and possesses more power of delighting the sense, while it speaks to the intell ect; but it is, nevertheless, nothing more than language, and all those excellen ces which are peculiar to the painter as such, are merely what rhythm, melody, p recision, and force are in the words of the orator and the poet, necessary to th eir greatness, but not the tests of their greatness.

这种语言的确比那种语言难学，当它诉诸智力时，也更能使人的感官感到愉悦。然而，它仅仅是语言，画家认为独特的各种优点，也就相当于诗人和演说家语言具有的节奏、旋律、精密和力量，这些只是他们伟大的必要条件，而不是检验他们是否伟大的标准。

I did not, for an instant, lose sight of , or undervalue, that part of the truth which I had seen before; I never turned recreant to intellectual culture, or ceased to consider the power and practice of analysis as an essential condition both of individual and of social improvement.

我没有，一会儿，忽视，或低估，这是我以前见过的事实的一部分，我从来没有把怯懦的知识产权文化，或不再视为一个必要条件两方面的权力和实践分析个人和社会进步。

The radial rectilinear stretching motion is firstly analysed, and its condition is deduced. Then two planetary gear mechanisms are assembled to realize the motion. In addition, the kinematics and dynamics analysis of arm mechanism is done, which provide the theoretic basis for the selection of servomotor and for holding the good dynamics and static performance of the clean robot.

首先对其末端执行器的径向直线伸缩运动展开分析，得出了实现该运动的必要条件，并采用两组行星轮系与连杆机构的组合形式来实现末端执行器的运动，此外还对该机构进行了运动学和动力学分析，为电机的选择以及控制净化机器人的动态性能和静态特性提供理论基础。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
