One hand mechanical obstruct led to the increase of veinous resistance and the obstacle of microcirculation, the other hand the adhesive PMN was activated in excess, the white blood cells released a lot of enzymes, in which PMN-elastase can decompose the components of cell and many albumens, inclusive of immunoglobulin、alexin and fibrication. These components induced the injury of the pancreatic capillary vessels and cell and lysosome enzy made the tissue protein hydrolyze and produced unsaturated fatty acids, which destroyed the structure and function of cellar membrane. The inflammatory cellar factors activate other immunocytes to produce the injury and necrosis of tissue, which aggravated the pathological injury and led to shock、pyaemia and MODS. So ICAM-1 and LFA-1 played an important role in SAP. Frossard found that the expression of ICAM-1 in the rat model, especially in serum、pancreas and lung. All these showed ICAM-1 is an important factor in AP and concomitant lung injury.

胰腺小叶组织局部血管EC首先被激活，ICAM-1表达升高，与被激活的PMN表面表达的LFA-1相结合，"PMN-EC"相互作用加剧，一方面机械性阻塞毛细血管导致静脉阻力增加、微循环障碍；另一方面粘附的PMN过度吞噬或激活，当白细胞吞噬的颗粒不能被封闭隔离，连同细胞内的酶被释放出来，其中的PMN-elastase能够降解细胞基质中各种成分，水解多种蛋白，加重胰腺的毛细血管内皮细胞和腺泡的损伤；释放的溶酶体酶使组织蛋白水解，产生的不饱和脂肪酸引发脂质过氧化方应，破坏细胞膜的结构和功能；释放的炎性细胞因子，激发其他的免疫细胞的功能，导致进一步的组织损伤和坏死，加重SAP的病理损伤，最终导致休克、脓毒血症及多器官功能障碍等严重后果。

Through analyzing the mechanism of FFT, an approximate formula for image transformation is proposed at first.

本文主要围绕着局部支撑的基函数展开，建立了一系列视觉信息处理模型和快速算法。

In addition, it's also very difficult to generate the closed surface fitting the outer nodes of the deformed material, the details includes locating the vertex, surface edge and loop.

本文提出基於畸变网格的质量优化和局部网格加密／稀释是最佳的解决方法，既可以保持初始网格的拓扑结构，还可以有效地避开网格再划分问题。

It investigates mainly the dualinvariant of λ- multiplier convergent series, the full invariant ofλ-multiplier convergent series, the λ- multiplier convergent series in spaceswith a basis, the compact sets in the infinite matrix topological algebras, thecharacteristics of have the same compact sets in different topologies,the weak sequentially completeness of , the characteristics ofSchur-matrices, the characteristics of p- uniform Toeplitz matrices and theEberlein-Smulian theorem in the locally convex spaces, etc.

主要研究了〓数乘收敛级数的对偶不变性，〓数乘收敛级数的全程不变性，有基空间中的〓数乘收敛级数，无穷矩阵拓扑代数〓中的紧集，〓在不同拓扑下具有相同紧集的刻划，〓的弱序列完备性，Schur—矩阵的刻划，p-一致Toeplitz矩阵的刻划以及局部凸空间上的Eberlein—Smulian定理等。

A meso mechanical analysis has been conducted on a hot-rolling steel of 16MnR toinvestigate the effect of the elongated pre-damage voids on the subsequent damage evolution and fracture process under the maximum normal stresses with various directions. The analysis results show that, when the elongated voids due to the decohesion of the inclusions from base material are loaded subsequently, the local high stress and strain concentration around the voids and their interactions promote the growth of voids.

对热轧钢中的长条形初始损伤孔洞承受不同方向最大正应力时的后续损伤演化和断裂过程的细观有限元力学分析研究表明：热轧钢中的长条形夹杂物与基体剥离后形成的长条形孔洞在后续加载中，其周围产生的局部高应力应变集中及其相互作用，使孔洞长大。

Parotid region skin shows vasodilatation, flush and diaphoresis in meal. The mechanism is aberration-regenerate theory. The treatments include drug treatment, local treatment and operation treatment. The obviate is to put interval stuff in operation, skin flap can prevent nerves wrong to unite on parotid raw surface. It can barricade insulate the wrong unite of parasympathetic nerve and reign skin interneural if insert apo-cell subcuticula ground substance in operation.

腮腺区皮肤在进餐时出现血管扩张、潮红、出汗现象，其机制为迷走再生学说，其治疗有药物治疗、局部治疗、手术治疗，预防主要是术中放置间隔材料，皮瓣在腮腺创面上防止神经错联发生；如术中植入脱细胞真皮基质，屏障隔离副交感神经与支配皮肤神经间的错联。

Based on this idea, in this paper, we used an infinitely differentiable wavelet with a local support. Its properties are different from those of orthonormal wavelet bases.

基于这一思想，本课题所使用的小波不象一般的正交小波基局部性和正则性是冲突的，相反，它既是局部支撑的，又是无限光滑的。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
