Third, it has a discussion on the development of modern and traditional artificial neural network technology and their application in image processing. It summaries that the model of the Pulse-coupled neural network based on Elkhorn's model of the cat visual cortex was constructed according to the mammalian vision systems. The nonlinear modulation property, which is a generic and pervasive biological pulse-coupling mechanism, is used in the construction of PCNN. So, PCNN finds many applications in image processing, including segmentation, edge extraction et al. As all known, the performance of the image segmentation depends not only directly on the adjustment of PCNN parameters and the statistical properties of image but also on the cyclic iteration times N of PCNN. If the parameters have been properly set, it turns out to be essential to select a suitable criterion to determine N.

回顾了神经网络技术的现状，指出传统人工神经网络只利用了生物神经元有限的属性进行模型构建，而90年代产生的脉冲耦合神经网络充分利用了哺乳动物视神经网络特有属性，其神经元模型除了考虑生物神经元特有的线性相加、兴奋与抑制属性外，还考虑到生物神经元特有的非线性相乘调制耦合特性；考虑了哺乳动物视神经系统视野受到适当刺激时，相邻连接神经元同步激发产生35Hz～70Hz振荡脉冲串特性等，所以PCNN网络模型更靠近真实生物视觉特性，特别是哺乳动物视神经网络，特别适合计算机图像处理应用，尤其在生物细胞图像分割、图像平滑、降噪及图像中目标的分类、计数等方面的研究。

The analyses indicate that some points from the specific phenomenon of sedimentation to the expansion of knowledge of source rocks, from Reflection on the gradual slow migration get mechanisms of hydrocarbon quick migration and reservation, from conventional fractural distribution to the possible newly exploration area produced by rapid deformation of fracture, direction from drilling trap to the possible condition of trap damaged, which causes great influence on the Oil and Gas Exploration.

分析认为，从特异沉积现象引出的烃源岩的扩展性认识、从渐变论的缓慢运移中反思得到的快速运移成藏、从常规的裂缝分布到快速变形过程可能产生的新勘探区域、从单纯钻进圈闭到解析可能的圈闭破坏条件等，这些理论都可能对油气勘探产生重大影响。

The great ring emerging with glory caused by ice cloud and fog is in fact an anti-solarhalo,which is leading to a conclusion that the dominant Van de Hulst's backward scattering theory on the formation of glory in recent years can not be used to illustrate all phenomenon concerning glory and gives a denial to the formulation that ice cloud and fog cannot produce any glor...

由冰晶云雾产生的宝光，其伴生的大光环实为对日晕，从而肯定了近年来盛行的范氏宝光形成的后向散射机理，不能用以解释一切宝光现象，否定了冰晶云雾不能产生宝光的局限认识。还指出了《国际气象词典》中&布格晕&条释义的错误。

The formation mechanism of the hollow and helical fibers was proposed. During the heat treatment, the hollow fibers could be formed when the inner gel of the thinner precursor fibers was separated from the center and contracted to surface. However, the helical fibers could be generated when larger gel fibers were broken helically under thermal stress in the process of gel decomposing and contracting.

分析了中空纤维和螺旋纤维的形成机理，直径较小的前驱体纤维在热处理过程中内部凝胶向表层迁移收缩形成中空纤维；螺旋纤维是由直径较大的前驱体纤维在热处理过程中产生的强大的热应力导致纤维产生螺旋破裂形成的。

In addition, during the procession of improvisate creation , the emotional resonance may be in a random way and there is, it will produce a class of "titleless" poem, which are mostly caused by the surrounding environment.

另外，在即兴方式创作中，有一种特殊的情况，如果作者是以一种游戏的方式进行创作的，这类诗的创作意旨具有不确定性，这就使得共鸣情感以一种随机性的方式而存在，这就会产生出一类&有名而实无&的诗，这类诗大多是有环境引发而产生的。

Of the client pay no attention to what solution causes to refuse, the psychological pressure of generation everyday its dial not tire of irritatedly client phone, confront a client do not understand, the rejection of 99%, psychological pressure is enormous, produce the feeling of understanding gradually.

客户的不理解造成的拒绝，产生的心理压力天天不厌其烦的拨打客户电话，面对客户的不理解，99%的拒绝，心理压力巨大，逐渐产生会心的感觉。

Seen from clinical effect, haemodynamics and general condition both better in rats treated with dexamethasone than rats treated with saline. We had a presumption on these grounds that the sum of negativity myodynamia generated byβ3-AR up-regulation andα1-AR down-regulation possibly less than positive myodynamia generated byβ1-AR up-regulation. 5 For patients with DCHF, adding prednisone to the usual care resulted in significant relief of the congestive symptoms, which was accompanied with a potent diuresis with time and an improvement in renal function.

从临床效果来看，地塞米松治疗的心衰大鼠在血流动力学及一般状况上，都明显优于注射生理盐水的心衰大鼠，据此推测，β3受体上调和α1受体下调产生的负性肌力之和可能弱于β1受体上调产生的正性肌力。5对于失代偿的充血性心力衰竭病人，在心衰常规治疗基础上加用强的松这种糖皮质激素能显著缓解充血症状，并伴随着强有力的利尿和改善肾功能的作用。

It is stated that multipath is closely related with observation environment and receiver performance. In more detail, receiver is classified as coherent delay loop and noncoherent delay loop by its operation. Their tracking properties for GPS signals are determined by discriminator curve.

GPS 中的多路径效应是在一定的观测环境下产生的，不同的 GPS 接收机所受到的多路径效应影响也有所不同，因此，除观测环境外， GPS 接收机内部工作机理与多路径效应的产生是密不可分的。

Therefore, the uplink cross-pol interference that we meet is normally caused by the polarization angle mismatch of ground transmitting antennas, or serious overdriven of the uplink power at cross-polarization. And the downlink cross-pol interference is normally caused by the polarization angle mismatch of ground receiving antennas.

因此，常见的反极化干扰通常为，因反极化地面发送天线的极化角失配、或因反极化载波的上行功率严重超标而产生的上行反极化干扰，以及因地面接收天线的极化角失配而产生的下行反极化干扰。

By 16S rRNA. When it was cultured in MMSW substrate, adding MWFO and SWFO as the carbon source, it could produce crude biodemulsifier of 4 g/L and 3.5 g/L respectively. Compared with biodemulsifier produced by paraffine as the carbon source, both of them could achieve higher demulsification ratio in breaking W/O and O/W model emulsion.

的一株破乳剂产生菌，在以废弃油脂MWFO、SWFO为碳源培养下，得到的生物破乳剂的粗重为4 g/L、3.5 g/L；对于W/O、O/W模型乳状液的破乳效果均可超过以液体石蜡产生的破乳剂，且以SWFO废弃油脂培养得到的生物破乳剂可以同时应用于两种模型乳状液的使用。
