Finally, we deal with the stability problem of the Bergman kernel, i.e., do the Bergman kernels of D_k. converge to the Bergman kernel of D on compact subsets of D × D where D_k i-s a sequence of bounded domains converges to a bounded domain D in the sense of Boas?

最后我们研究Bergman核的稳定性问题，即，若一列有界域D_k按Boas意义下收敛于一个有界域D，是否有D_k的Bergman核在D×D上局部一致地收敛到D上的Bergman核？

They include the fundamental concepts of jet bundle geometry needed in describing time-dependent mechanical systems, decomposition of jet bundles into a direct sum according to the constraints, horizontal distributions on constraint mainifolds, the global formulation of D'Alembert-Lagrange's equations and Chaplygin's equations, and nonholonomic mechanics on a Riemann-Cartan manifold. Meanwhile, the geometric significance of Chetaev's conditions and $\rd$-$\delta$ commutation relation are discussed in depth.

In Chapter 2, the D-symmetric solutions of matrix equation A~TXA = B on the linear manifold S ={X ∈ D~(-2)SR~|XZ = Y, Y = Y{D~2Z+D~2Z, Z~TD~2Y = Y~TD~2Z, Y,Z∈ R~}, by applying the generalized singular value decomposition of a matrix pair, the necessary and sufficient conditions for the existence and the expressions for the D-symmetric solutions of matrix equation A~TXA — B on the linear manifold are established.

RESULTS: The average dose of venlafaxine was (196±s 48) mgd^(-1), the average effective time was (8±3) d, and the effective rate was 68%. The average dose of mirtazapine was (32±11) mgd^(-1), the average effective time was (12±6) d, and the effective rate was 65%. The scores after treatment were significantly decreased in both groups. The scores of HAMA were (33±3)%(wk 1) and (50±3)%(wk 4) in venlafaxine group,(14±3)% and (31.0±2.3)% in mirtazapine group.

结果：文拉法辛组治疗剂量为(196±s 48) mgd^(-1)，显效时间(8±3) d，有效率68%，米氮平组分别为(32±11) mgd^(-1)、(12±6) d、65%。2组疗效量表评定结果均较治疗前有显著下降，特别是文拉法辛组wk 1和wk 4的HAMA减分率为(33±3)%和(50±3)%，米氮平组为(14±3)%和(31.0±2.3)%，前者下降更为明显。

He also cautioned that vitamin D is not a panacea."The effect of vitamin D on symptoms is relatively small," he said."This is not going to make someone with a lot of knee pain feel all better usually. It's a minor contributor, but it's such an easy correctible, it would be silly not to pursue ."

他同时指出，维生素D并不是一个万灵丹，维生素D对症状只有轻微的影响，一般而言，并不会因此而让人膝盖疼痛的现象一下子好转，因此只能作出次要的贡献；但是这是很容易做到的，何乐而不为。

Through the consideration of the triplet-state configuration of d-TMA and the effect of heterolytic reaction on system entropy value,△H and △S of the dissociation reaction of d-TMA were accurately calculated at the same time. The plot of lnK vs l/T had a perfectly linear relation: lnK=-9624.4363/T+20.2303, and the correlation coefficient R^2=1.0000, which agreed quite well with the predecessors' experimental results.

通过考察d-TMA三线态构型和异裂反应对系统熵值的影响，准确计算了d-TMA离解反应的△H和△S以lnK对l/T作图，两者之间具有很好的线性关系：lnK=-9624.4363/T+20.2303，相关系数R^2=1.0000，与前人实验结果相当一致。

Vancomycin was directly coupled onto Tenta Gel S NH〓 or PEGA resin through its C-terminus. HR/MAS NMR studies indicated that conformation of PEGA-bound vancomycin was the same as free vancomycin, and Ac〓-L-Lys-D-Ala-D-Ala interacts with PEGA-bound vancomycin the same way that it interacts with free vancomycin.

本文将万古霉素C端分别连接到Tenta Gel S NH〓和PEGA树脂上，利用高分辨魔角核磁共振技术研究了万古霉素在固相载体上的构象变化以及与Ac〓-L-Lys-D-Ala-D-Ala的相互作用。

An early baby-boomer, Mr Gekoski comes of age in the company of J.D. Salinger's "The Catcher in the Rye" and Allen Ginsburg's "Howl", delves into psychoanalysis in the dubious company of R.D. Laing, discovers philosophy guided by René Descartes, David Hume and A.J. Ayer and literature with W.B. Yeats and Carl Hiaasen.

杰柯斯基生于婴儿潮早期，读着J·D·赛林格的《麦田里的守望者》和艾伦·金斯伯格的《吠》长大；后来他抱着怀疑的态度阅读R·D·莱恩，进而开始了对心理分析学的深入研究；又通过笛卡尔、大卫·休谟和艾尔的著作对哲学有了一定了解；他在叶芝和卡尔·海森身上学到了文学。

According to Beverly Hills dentist Harold Katz, D.D.S., the best way to brush is by placing your toothbrush at a 45-degree angle against your gums and gently moving it in a circular motion, rather than a back-and-forth motion.

根据比佛利山庄牙医 D.D.S。哈罗德卡兹的说法，最好的刷牙方法是把你的牙刷以 45 度的角度放到你的牙龈上，并且以圆周运动轻轻移动它，而不是前后运动。
