稳定分布

It is demonstrated that the frequency drift will break up the phase-locked state of the laser array and induce the spatial instability of the far-field intensity due to phase noise. It is also found that although the evanescent coupling between elementary lasers can restrain these effects to some extent, the restrainability is too limited to be effective when the frequency drift is relatively strong.

通过对耦合激光器阵列动力学方程的数值研究发现，频率漂移将破坏激光器阵列的锁相状态，并引入相位噪声，导致输出远场光强分布不稳定；研究还发现：倏逝波耦合能够对频率漂移的影响起到一定的抑制作用，但这种抑制只在频率漂移较弱时才有效，因此，如果将该阵列用于光束合成，加入相应的抗干扰措施还是很必要的。

The central complex isprominent. The beetle showed notable 5-HT-like immunoreactivity throughout the wholebrain, which was also strongly labelled by TPH antibody, with the pattern matching that of5-HT. 5-HT-like positive fibers were resolved in all areas of the brain, among which thelamina and suboesophageal ganglion showed the most remarkable dark brownimmunostaining. While, all major neuropil regions, in general, showed low level backgroundafter TPH immunostaining for TPH mainly existing in cytoplasm. The number of 5-HT-likeimmunoreactive neurons was relatively small but possessed extensive varicose arborizations.

免疫组化结果显示，异色瓢虫脑系统呈强5-HT免疫反应，表现为稳定的反应模式；其脑系统对鼠抗TPH单克隆抗体同样呈显著的免疫阳性反应，且反应模式与5-HT一致。5-HT能神经元多为切向神经元，数目相对较少，呈两侧对称分布，主要位于视叶与侧前脑之间、前脑背方及咽下神经节处，其阳性纤维呈明显的静脉曲张状，投射区域较广泛。

The result indicated that we can get stable homopolymer and copolymer emulsion with uniform size distribution, when the ratio of sodium polyether sulfovinate modified polysiloxane to sodium lauryl sulfate was two, the quantity of the emulsifiers ranged from 6% to 8%, the quantity of initiator ranged from 0.4% to 0.8%, the stirring speed ranged from 200rpm to 250rpm, the polymerization temperature was 80 centigrade degree. As for the copolymer emulsion, the more the TRIS content in the monomers, the larger the water contact angle of their films became, namely, the surface energy of the copolymer films increased with the TRIS content in the monomers. In addition, the glass-transition temperature of the copolymers ranged from high temperature region to low temperature region with the increasing of TRIS content in the monomers.

结果表明：当乳化剂用量在6%～8%、改性乳化剂与十二烷基硫酸钠复配比为2：1、引发剂用量在0.4～0.8%、聚合温度为80℃、搅拌速度在200～250rpm时，得到的均聚物和共聚物乳液稳定，而且粒径分布均匀；对于共聚物乳液来说，随着单体中TRIS含量的增加，所得聚合物膜的水滴接触角增加，即其表面能增加：另外，随着共聚单体中TRIS含量的增加，共聚物的玻璃化转变温度从PMMA的Tg的高温区向PTRIS的Tg的低温区移动。

结果 ：与正常对照组(33人)相比，强迫症患者波形稳定差，2 3例(6 3 。9%)出现额叶波形变异或两侧不对称；N2、P3的潜伏期明显后移；波幅下降；36例患者的P3地形分布图均失正态分布，正常顶区高功率消失。

The associated factors, clinical signs, treatment and prognosis were discussed. Result: Nine patients (6 female and 3 male) were included in this study. All of the patients were associated with myopia, ranging from -0.5 diopters to -5.0D. Gonioscopy revealed a dense homogeneous pigmented band seen over the entire circumference of the trabecular meshwork in all patients; however, no patients with iris transillumination defects were detected. Two of the patients developed pigmentary glaucoma and were treated with β-blocker, miotics and argon laser trabeculoplasty.

Because the steady state probability of the M/G/inf queuing system is related to the average packet length only and not related to the distribution of packet length, we propose M/M/inf model for the DS CDMA/unslotted ALOHA system with variable number of fixed-length packets. The analyzed throughput of M/M/inf queuing model is closer to the simulation throughput than the analyzed throughput of M/M/1 queuing model is.

由於M/G/inf在稳定状态下的机率只与平均封包长度有关，与其分布状况无关，所以我们提出M/M/inf模型来分析直接序列分码多工/非同步阿罗哈系统同时拥有可变的固定长度封包数。M/M/inf排队模型生产效能分析结果会比M/M/1排队模型的生产效能分析结果更接近系统生产效能的模拟曲线。
