Later, in people's intellectual level of a significant increase, with the carriage, such as animal transport, but also the history of transport is a "huge" leap forward, and this is also relative to promote the inter-tribal, exchanges between the ruling and opposition parties to form a small area of a virtuous circle, soon after, water transport has gradually forming, but also the rapid development of transport being used on the battlefield in the Three Kingdoms period, each World War II will gather the best tools and transport operations (but no longer advanced only species breeding horses and bad horses very small difference between).
后来,在人们的智力水平有了显著提高后,有了马车等畜力交通工具,也算是交通工具史的一个"巨大"的飞跃了,这也相对的促进了部落间、朝野间的交流,形成小范围内的良性循环,之后不久,水上的交通工具也逐渐成型,不过交通的迅速发展也被利用在战场上,在三国时期,每次大战都会聚集最顶尖的作战工具和交通工具(不过再先进也只是良种马和劣种马间的极小的区别)。

Cyclic voltammetry indicated that there were Cr→Cr, Cr →Cr oxidation reaction on anode, while there were Cr→Cr, Cr→Cr, Cr →Cr deoxidization reaction on cathode. The graphite electrodes treated by acid and heating could enhance the reversibility and kinetic of the electrode reaction. The nature graphite electrodes had been eroded during charge/discharge process, while the graphite electrodes by activation could avoide corroding by hexad chromium ion. The reversibility and kinetic of the electrode reaction of chromium ion on activation electrode had been increased, so which indicated that graphite surface augment oxygenous function corps which could increase electrode hydrophile capability.

Aside from pancreatic enzymes activiation and autodigestive process, recent investigations have established that the upregulation of inflammatory mediator are believed to be the critical steps in the progression of mild pancreatitis to severe pancreatitis. Tumor necrosis factor-, ThyomboxaneA2 ,ProstaglandinsI2 are all important inflammatory mediator. TNF-( is one of cytokines. It is important to the over-production of ICAM-1,VCAM-1, TXA2 andPGI2. The ICAM-1 and VCAM-1 mediate both leukocytes adhesion and migration through the endothelium into tissues to connect with injuried target cells. The TXA2 and PGI2 are the production of arachidonic acid. They are responsible for the tissue ischaemia.

Preparation of the cathode includes:shaping under the press of 40Mpa, sintering at 550℃for 1 hour and at 900℃for 8 hours and threading with molybdenum bar; Considering the literatures we choose CaCl2 as salt for preparation titanium. Pretreatment of salt is for 1 hour at 100℃and for 2 hours at 300℃. Partial pressure of oxygen which need lower than 5.11×10-7Pa to reduct titanium oxides and hygroscopic property of salt need a sealed equipment to electrolyse. And finally successfully designed a satisfied one and the results show that the equipment can be satisfied the requirment of the experiment. Flow of the inert gas is 1.5L/min, the voltage is 2.8 V, temperature is 850℃and time is 2 hours during pre-electrolysis. Flow of the inert gas is 0.2L/min, the voltage is 3.1 V, temperature is 900℃and time changes with the mass of TiO2 during electrolysis, namely the greater need the longer time; To eliminate influence of salt and other impurities, the products need to wash with distilled water and dilute chlorhydric acid , then wash with dilute hydrochloric acid under supersonic wave assistant. Finally, electrometical properties of the electrolysis of TiO2 is researched by cyclic voltammetry and chronoamperometry, and results show that there are two main reodox steps, namely from TiO2 to TiO and from TiO to Ti.
阴极制备主要包括40MPa压力下模压成型、两段式烧结(1小时内升至550℃保温1小时,再1小时升温至900℃保温8小时)及烧结后TiO2块打孔用钼棒串接三个主要环节;实验中选用CaCl2作为电解熔盐,并对其进行预处理(100℃,保温1小时; 300℃,保温2小时);经热力学计算,还原钛氧化物的氧分压至少要低于5.11×10-7Pa,结合电解过程中所用熔盐CaCl2有极强的吸水性的特点,电解装置应有较高的密封性,自行设计了一套密封性可靠的电解装置,便于实验过程中熔盐预处理和氧分压的控制;通过干燥处理预电解过程中Ar流量大约为1.5L/min、电压为2.8 V、温度为850℃、时间为2小时,电解过程中Ar流量大约为0.2L/min、电压为3.1V、温度为900℃,实验结果表明电解时间与TiO2质量密切相关,质量越大需要电解的时间越长;通过自来水冲洗—稀盐酸浸泡、洗涤—在超声波辅助作用下稀盐酸洗涤,可减少熔盐及其它杂质对电解产物检测结果的影响;最后,通过循环伏安法、计时电流法对电解机理的研究,确定电解还原TiO2制备金属钛主要经历了TiO2-TiO-Ti的过程。

The humidity resistance and the sensitivity to chemical warfare agents simulants of the tuned films were also investigated.Self-assembled LBL polyaniline films were prepared from aniline monomers by in situ polymerization and the mechanism of film formation was discussed. It was proposed that the self-assembly of polyaniline occurred through the quick absorption of aniline monomer cations or aniline monomer cation radicals on the glass surfaces by electrostatic attractions to form homogeneous polymerization centers, then increased gradually by the way of upright to the glass supports for extensity, leading to the polyaniline chain growth. The polyaniline was doped under acidic condition to absorb anionic polyelectrolyte, such as sodium polystyrene sulfonate based on the electrostatic force, or to adsorb polymer based on hydrogen-bonding interactions, for example Polyvinyl Alcohol, and then recycled to fabricate_n or_n self-assembled multilayer films.

在数千年的造纸发展史上,传统的湿部化学品的加入和混合一直是利用加后稀释水的方法通过静态在线混合器来完成的,由于湿部化学品的加入量很小,,其流量仅为 0.1~1升/秒甚至更小,而要将如此之小的流量加入到纸机流浆箱300 ~2000 升/秒的工艺系统浆料流体中,同时达到化学品与造纸纤维均匀接触,即使是消耗大量的清水和使用在线混合器也很难达到&完全&且&有效&地混合,于是就又产生了将化学品的加入点,提前到远离流浆箱的工艺位置,这样可以延长混合时间,但人们忽略了在过早加入化学品的同时也带来了化学品的流失、化学品在短循环系统循环产生有害副产物生成浆管悬挂、化学品水解失效等一系列弊病。

Quantitatively, the optical density of NADPH-d positive neurons in all of the related nuclei was significantly increased in the BDL animals compared with controls. Since NO is thought to be able to increase the motilities of the gallbladder and the sphincter of Oddi in anesthelized rabbits, the elevation of NADPH-d and NOS reactivities is likely to magnify the excitatory effect on the extrahepatic biliary system for the purpose of depletion of the loitered bile juice from the jaundiced liver. These data may also have important implications for the altered state of circulatory, metabolic or regenerative responsiveness under pathological condition.
此现象一来可推测,肝脏在遭受胆管阻塞性黄胆的伤害后,其代谢、血液动态与温度调节作用势必改变、紊乱、甚至失功能,而感觉神经也势必会接受到大量的机械性、化学性、渗透性等感知讯息,所以感觉神经元将一氧化氮制造量提升,有助於感觉讯息的快速传报,以发挥回馈调控的效果;二来可表示,自主神经系统不论是交感或副交感神经,为了因应胆管阻塞所造成肝脏的病变,以增加一氧化氮的制造,意欲刺激肝外胆道系统,排空滞留在肝脏内或胆囊内的胆汁,而达到恢复肝脏内代谢、血液循环、胆汁流动等功能控制的恒定状态。
