The effect of crude chitinase on three pathogens showed that it could degrade the cell-wall of thepathogens.The crude chitinase could make Fusarium spp and Alternaria spps cell-wall thin andrupture,cell-wall and bioplasm separate,the bioplasm of Rhizoctonia solani distribute asymmetry andbecome vacuole,the cell-wall thin and rupture also.

几丁质粗酶对三种病原真菌菌丝细胞壁的降解作用显示，几丁质酶可使交链孢和镰刀菌菌丝细胞壁变薄、溶解、质壁分离、原生质膨大；丝核菌原生质体分布不均匀、空泡化、细胞壁变薄并出现断裂现象。

Because of embedded option, the cash flow of callable bond is not certain. Fortunately, it has the same future cash flow as the portfolio of one long noncallable bond and one short call option on the callable payments. So under a nonarbitrage condition, the value of callable bond equals the difference of the value of noncallable bond and call option.

由于内嵌看涨期权的存在，可赎回债券的预期现金流事先并非确定，但因其未来的现金流表现与持有可比普通债券和卖空看涨期权的投资组合相同，故而可赎回债券的价格在无套利条件下应等于可比普通债券减去看涨期权的差值，也就是说用于普通债券的一般定价和度量方法并不适用于此种特殊的选择权债券。

Barrington's nucleus that located in the pontine dorsolateral tegmentum is an important site for controlling voiding in the mammalian brain and is often referred to as pontine micturition center. Barrington's nucleus sends direct projection fibers to the sacral parasympathetic nucleus in which parasympathetic preganglionic neurons innervating detrusor muscles of the bladder are distributed. Electron or chemical stimulation of Barrington's nucleus clicits bladder contraction and increases discharges of bladder postganglionic nerve. Conversely, lesion of the nucleus results in a permanent inability to empty the bladder. On the other hand, an area located just ventral to Barrington's nucleu has been reported to send projection fibers to the ventrolateral group of Onuf's nucleus in the caudal lumbar cord segments; the vetrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.

Barrington's核发出纤维投射至支配膀胱逼尿肌的骶髓副交感核，毁损该区可导致动物永久性失去排空膀胱的能力；而电刺激或化学刺激该区可引起支配膀胱的节后纤维放电增加和膀胱逼尿肌收缩。D区是紧邻Barrington's核腹侧的一团神经元，它发出纤维投射至腰骶髓Ounf核的腹外侧群，而Ounf核的腹外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

The results show that the porosity of the membrane prepared by ScCO_2 induced phase separation is higher than that prepared by conventional method;the membrane structures are significantly influenced by the process parameters;compared with the conventional immersion precipitation phase inversion,ScCO_2 induced phase separation process can effectively avoid the formation of macrovoids at suitable operating conditions;during depressurization process,the great differences in the effect of depressurization time on membranes structure for various polymer materials result from that the speed of CO_2 gaseous nuclei escaping from membrane substrate can not keep the pace with the outer depressurization rate.(2) The tendency that the interaction parameters affect the binodal curve position is illustrated by changing the interaction parameters in reasonable ranges.

研究结果表明：与传统方法相比，采用ScCO_2诱导相转化法可获得更高的膜孔隙率；通过改变操作参数可对膜的结构进行调控，且操作参数对膜结构的影响与铸膜体系的自身性质也紧密相关；在适宜的操作条件下，ScCO_2诱导相转化法能有效避免采用传统的浸入沉淀相转化法制膜时易出现的大空腔结构；泄压过程中CO_2气核从聚合物膜基体中逃逸的速度能否与膜基体外部的泄压速度保持同步，是泄压时间对不同材质膜结构影响截然不同的根源所在。

Bioclimatic architecture realizes low energy-consumption natural ventilation: the squama-curtain of TBA TOWER has opening window and special ventilation fan, realizing air ventilation across both sides of the mansion through pressure difference between windward side and leeward side, under the condition of no pressure difference, it can form chimney effect through vacant areas in the mansion, create negative pressure in the internal capsule, import air into device layer and discharge it, realizing the circulation of fresh air, not only saving energy and improving air quality in the room, but also bringing benefits to the health and mind of inhabitants.

Take a cable car in the more sea and air taxi, overlooking Port thousands of United States Department of vessels, many of the raft Shengjing; visitors bathed in a cool sea breeze, far from clean look attractive and charming beach scene in the swaying coconut, Bai Yun considerable embellishment after another blue sky, sea and the sky can be seen Skyline Department Isshiki, the pleasant scenery is memorable.

乘缆车在海面上越空滑行，可俯瞰港口处千帆竞发，渔排林立的盛景；游客沐浴着凉爽的海风，可眺望远处洁净迷人的沙滩与妩媚多姿的椰林随风摇曳，可观白云朵朵点缀蔚蓝天空，可见天际线处海天一色，怡人的美景令人回味无穷。

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。
