光抑制

It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.

众所周知，晶格失配和热应力失配是GaN异质外延中位错产生的主要原因；为此，我们对几种降低缺陷的MOCVD外延生长方法进行了新的尝试，其中尝试了侧向外延生长技术，得到了低位错密度（小于10〓/cm〓）、高质量的GaN外延层；尝试多低温缓冲层法，发现材料中的应力特性与生长系统和生长条件有关，材料中的应力与位错密度按相反方向变化；首次尝试高低温联合缓冲层法，材料中高温缓冲层可以使随后的低温缓冲层中成核颗粒增大，从而导致随后高温GaN外延膜中位错密度降低，并且能够有效地抑制黄光峰。

The results indicated that GABAmay be the important inhibitory neuropeptides; VIP,β-EP, SP also involved in theregulation of the GnRH. Optical information may control the chicken productionperformance by adjusting the distribution of GABA, VIP andβ-EP neuropeptides withinthe nuclei related to the tectal layerⅠ.

Valinomycin, a photophosphorylation uncoupler, decreased significantly the fast phase (related mainly to the membrane electric potential) millisecond delayed light emission of C. reinhardtii. Nigericin, another photophosphorylation uncoupler, decreased the slow phase (related mainly to the proton gradient) and partly also the fast phase of ms-DLE. Both valinomycin and nigericin can decrease the net ATP content under light and photosynthetic rate of C. reinhardtii, but the degree of inhibition of net ATP content and photosynthesis by nigericin was higher than that by valinomycin.

光合磷酸化解联剂缬氨霉素显著降低衣藻毫秒延迟发光的快相，对慢相影响不大；另一个光合磷酸化解联剂尼日利亚菌素则显著降低衣藻毫秒延迟发光慢相（主要与跨膜质子梯度有关），同时也降低部分快相。valinomycin和nigericin均可降低光下藻细胞中的ATP净含量和光合作用速率，但是nigericin对ATP含量和光合作用速率的抑制程度比valinomycin强。

To meet the needs, a novel low-noise fiber laser with compound cavity structure is designed. The stable single-mode operation is realized by using a transient self-written fiber grating, produced by the effect of saturable absorption within a section of unpumped erbium-doped fiber, as narrow band filter for mode selecting and linewidth squeezing. Through optical path modification, the spectral signal-to-noise ratio is better than 62 dB.
