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.

讨论了n 维球面上某些可微函数类的Fourier Laplace级数的绝对收敛性，其中指出：设f是Hrp上 2 ( [n4 ]+1)次连续可微函数，则级数∑∞k =0 Ykf一致收敛到f参

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.

四个栽培棉种间杂交种F〓的细胞学观察结果表明，F〓减数分裂中期Ⅰ，形成一个环状四价体，直接证明了亚洲棉与草棉之间存在一对相互易位；F〓减数分裂中期Ⅰ联会基本正常，主要形成二价体，偶尔出现一些单价体和多价体，以及染色体桥。

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.

实验淬火产物包括结晶相石英，长石(碱性长石，钠长石、钾长石)，铁锂云母和黄玉及玻璃相和微量流体，对固相淬火产物进行了系统和详细的显微观察及电子探针和x射线分析，研究了F对钠长花岗岩液、固相线温度、相关系和相组合的影响和含F钠长花岗岩的结晶序列和熔体演化、F在流体和熔体之间的分配及F对花岗质熔体结构的影响，对含黄玉矿物组合进行了一系列热力学矿物平衡计算，获得如下重要结论

METHODS: By using Vision Monitor visual evoked response imaging system, the standards for five obtained Flash Electroretinogram were recorded on 53 normal subjects (73 eyes), including F-ERG to a weak flash in the dark-adapted eye,F-ERG to a strong flash in the dark-adapted eye, oscillatory potentials, F-ERG to a strong flash in the light-adapted eye, and F-ERGs to a rapidly repeated stimulus.

By means of experiments of marker transfer,acridine orange sensitivity test,F' curring and mini-chromosome transformation it is.conchi-ded that the F' plasmid is always in an integrated state in the Sin strains and that the initiation of the replication of the bacterial chromosome is carrie...

标记转移、吖啶橙敏感性，F′质粒消除和mini-染色体质粒转化等实验说明，Sin菌株中F′质粒始终处于整合状态，并且在40℃中细菌染色体的复制由整合状态的F′质粒所带动。

There are no prominent variations of the micas in Li, F, Mn and Rb between zone c and zone d but sharp changes in these elements between zone d and zone e. In contrast to the primary micas in zone e, the altered micas in zone e show higher in F and Li but lower in Al. From zone a to zone e, the micas do not show remarkable variation in Na+K.

从c带到e带，随着Fe、Mg和Ti的减少，总体上表现为Al、Li递增，F、Mn和Rb递减的演化方向，但Li、F、Mn和Rb在c带和d带之间变化不明显，d带和e带之间却表现出急剧的变化。e带中的次生云母与原生云母相比，前者F、Li高而Al低，从a带到e带，Na+K变化不明显。
