先验性

In 1987,applying the connection of continuity method and aprior es-timate technique,Wang Guanglie,[11],got the existence and uniqueness of theclassical solution of (1)(2) under some compatibility conditions.

This present algorithm further distinguishes itself through sufficiently utilizes the advantage that the vector sensors provide from other beam space DOA algorithms in several regards: 1 beams are formed in the vector-field domain; 2 produce at moderate signal-to-noise ratio estimation performance comparable to the traditional scale array methods;3 these vector-field beams are formed blindly using no apriori source information and coarse estimates of the direction cosine are derived to start off MUSICs iterative search so it demand less computation; 4 deploy agilely , since the fact that the output channel is various .

本文提出了矢量传感器阵列的自适应综合校准补偿方法，还提出利用单矢量传感器速度协方差矩阵分解来求解目标源方位，使得我们不要求校准源是合作性的，也无需知道校准源的先验知识，这比起常规辅助源校准方法具备较大宽容性。随着高性能阵列处理技术及数字信号处理硬件的快速发展和矢量传感器制造工艺的不断成熟，矢量传感器将在新型水雷、低频远程智能鱼雷、声纳浮标、低频拖曳线列阵和新型舰壳声纳，灵巧传感终端，战场监视系统，反隐形雷达，通讯等军民用领域取得良好的发展应用前景。

Scheler proceeds from an objective viewpoint in analyzing values. In emphasizing an a priori nature of values, he avoids a lofty, superior attitude that would disenfranchise most from any discussion on the subject. Scheler posits an intuition of 'fondness', which caters to the intimate relationship between the spirit and a sense of value. Scheler's value studies take one to an unopen territory of speculation.

最后指出，身为价值客观论者的谢勒，在强调价值的先验客观性时，并非只是藉此把「价值」束之高阁，成为与人无关且高高在上的领域，而是同时提出直观的偏好，兼顾到人类心灵与价值的密切交融性，其价值学所开展出的道路，带领著人的思绪走向另一片天地。

We discussed the coupled generalized BBM equations with pseudodifferential operator in Chapter three.In this chapter we get the global existence for the Cauchy problem by Banach-fixed point theorem ,a priori estimates and Sobolev embedding theorem.

第三章讨论了具拟微分算子的广义BBM方程组，通过Banach不动点定理、解的先验估计和Sobolev嵌入定理得到了解的整体存在性。

The existence and the uniqueness of the difference solution are proved. Based on the priori estimates and an inequality about norms, the stability and the convergence of difference solutions with the second-order are proved in the energy norm.

利用矩阵理论证明了差分解的存在惟一性，并利用一个重要的不等式在先验估计的基础上，运用能量估计的方法证明了该格式按无穷范数以二阶精度收敛到真实解。

Using a new measure function to express the sparse prior information of SAR image, a regularized model is established. The model is solved by the fixed point iteration method and proved to be convergent.

本文采用一种新的度量函数表示SAR图像的稀疏先验，建立正则化模型，证明了不动点迭代求解的收敛性。

Now it is easy to show that there actually are in human knowledge judgments which are necessary and in the strictest sense universal, and which are therefore pure a priori judgments.

现在就很容易说明在人类的知识积累中确实有这样的判断存在，他们满足了必然性和普适性，因此它们便是纯粹先验的判断。

Chapter 4, consider the periodic initial value problem of a dissipative gen-eralized KdV equations. In section 4.2, the existence of global smooth solution of this problem is proved and the existence of the global attractors is obtained.

第三章，考虑高维的非齐次GBBM方程的初边值问题，建立与时间t无关的一致先验估计，证明了整体光滑解和整体吸引子的存在性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
