This paper investigates the absolute convergence of the Fourier Laplace series concerning of some smooth functions defined on the unit sphere in R n,hereinto shows that:if f is 2([n4]+1) th continuously differentiable function on H r P,then the series ∑∞k=0Y kf converges uniformly to f.

The effect of F 1C on joint swelling and the immune respones of AA rats were evaluated by lymphocytotic reaction, flow cytometry, and ELISA. Results F 1C by ig administration to AA rats decreased the primary joint swelling of AA rats, stronger than TW and weaker than CsA, promoted the decreased splenocyte proliferation induced by Con A, and inhibited the augmented thymocyte proliferation induced by Con A in AA rats. The evaluation in vitro showed the F 1C inhibited the augmented thymocyte proliferation from AA rats and promoted the deficient IgG produced by splenocyte from AA rats.

结果 ig给予F1C(30mg／kg)对AA大鼠原发性足肿胀具有明显的治疗作用，该作用较TW强，较CsA弱；F-1C对AA大鼠低下的脾细胞增殖反应具有改善作用；对亢进的胸腺细胞增殖反应具有抑制作用。F-1C体外对AA大鼠低下的脾细胞产生IgG水平具有明显的促进作用，并能抑制亢进的胸腺细胞增殖反应。

The cytogenetics of interspecific hybrids among the four cultivated cotton species were studied in this paper and results are as follows: The diploid interspecific hybrid (G. arboreum×G. herbacium) F〓 had a four-chromosome-ring at the meiotic metakinesis. The synapses of tetraploid hybrid (G. hirsutum ×G. barbadense) F〓 was found to be regular, which mainly formed bivalents, sometimes some univalents, multivalents and chromosome bridge.

By tailoring the scale between hydrophilic region and lipophilic region, smectic, columnar and cubic mesophases were observed in compounds I-F and II-F. By changing the length of the lateral chains, a series of new columnar phases and a non-conventional semctic phase were obtained in III-F.

通过调节亲水部分和亲脂部分的比例，在I和II-F中观察到了从近晶层相到柱相再到三维立方相的液晶相序列；在波拉分子III-F中通过改变侧链的长度，获得了一系列柱相及新型层相。

Meanwhile the defects are also studied by means of the methods of EPR, PSL, thermostimulated luminescence and absorption spectroscopy. These results indicate that the principal defects are F centers and O〓 in PSL. O〓 centers are formed by O〓 ions substituting for F ions with a trapped hole The trap depth of two kinds of F centers is obtained by using thermoluminescent spectra.

同时还利用电子顺磁共振谱，光激励发光，热释发光和吸收光谱的方法，研究了其材料中缺陷的性质，实验结果表明在光激励发光过程中主要的缺陷是F心和O〓心，其中，O〓心是O〓离子替代F〓离子并束缚一个空穴而形成的局域中心。

The experimental products include crystal phase quartz, feldspar (alkila-feldspar, albite, K-feldspar), zinnwaldite and topaz, a melt phase and a trace vapour. The solid products were been studied by optics method, electron microprobe and X-ray analysis. The results show that liquidus temperature raises slightly and solidus temperature falls down obviously and that the upper temperature limit raises for the stability field of quartz and topaz, and falls down for the stability field of alkila-feldspar as F contents in crease.
