The in vitro effects of Gln49-PLA_2 were examined using the chick biventer cervicis nerve muscle preparation. Gln49-PLA_2 caused a dosedependent blockade of neuromuscular transmission. The time required to cause 50% blockade was about 150 min at the highest concentration 100μg/ml. This inhibition appeared to be presynaptic in origin as evidenced by the lack of effect of toxin on responses to exogenous acetylcholine in the non-stimulated BCp.

Gln49-PLA_2能够剂量依赖性地抑制颈二腹肌神经信号正常传导并影响肌肉收缩，在100μg/ml剂量下，肌肉收缩幅度在150分钟后达到50%的抑制率；同时，随着Gln49-PLA_2浓度的降低，肌肉收缩幅度的抑制效率也逐渐降低；实验证明Gln49-PLA_2对突触后膜乙酰胆碱受体敏感性无影响，对神经肌肉信号传导收缩的抑制作用位点在突触前膜。

One who goes touring on foot with a single volume in his knapsack reads with circumspection, pausing often to reflect, and often laying the book down to contemplate the landscape or the prints in the inn parlor; for he fears to come to an end of his entertainment, and be left companionless on the last stages of his journey.

一个独步行走的旅人，只在包里装一本书，他细细地读，慢慢地品，时而停下来反思，时而欣赏周边的风景，时而察看旅途客栈里的版画。他慢慢地读，因为怕很快读完后就没有什么可娱悦的了，剩下的旅程里他就很可能要孤独寂寞了。

In the studying of image segmentation, six crucial technologies havebeen developed successfully. 1 In one dimension histogram of original DRimage of luggage, there remain maximum-value wave crest havingapproximately stationary position, and the first minimum to the left of thewave crest performs excellently to be used to get rid of background of DRimage. 2 Open operation, one type of math morphology, is the right idea toerase luggage disturbance in DR image and at the same time, can be retaininteresting region appropriately. 3 After open operation, there are only a few minimums on image histogram, one of which can be to segment image furtherand achieves satisfying result. 4 Method of histogram analyzing and that oferosion performs well in the re-segmentation of conglutinative region in DRimage. 5 Method of image distance switch can ensure Luggage CT sectionautomatically obtained to have rich suspicious region information. 6 Todecompose structure element of math morphology is a way to save a great dealrunning time for automatically discerning interesting regions algorithm,apparently improving implementation efficiency.

在对图像可疑区域分割研究中，主要开发成功以下几项关键技术：1发现原始箱包DR图像的一维直方图中，均具有位置相对稳定的最大值波峰，以波峰左边第一个极小值为分割阈值，去除DR图像背景，效果非常好。2运用数学形态学中的开运算能够非常有效地去除箱子的干扰，同时能够比较好地保留可疑区域。3发现开运算后的DR图像直方图只有若干个极小值点的特点，其中用最大值波峰左边的第二个极小值点进一步分割DR图像，能够更有效地提取箱包中的可疑区域。4运用直方图分析法和腐蚀法，对粘连区域实行再分割，效果较好。5运用距离变换法，能确保自动设定的箱包CT截面包含丰富的可疑区域信息。6运用形态学结构元素分解技术，大幅度减少可疑区域的自动判别算法运行时间，提高算法软件执行效率。

The Testament was not necessarily written: at first, it seems to have been invariably oral, and, even in later times, the instrument declaratory of the bequests was only incidentally connected with the Will and formed no essential part of it.

遗命&并非必须是书面的：在起初，&遗命&似乎一成不变地是口头的，并且，即使在较后时期，宣布遗赠的证书也只是偶然地和&遗嘱联系在一起而并不是它的主要组成部分。

After the performance, we go shopping and have the lunch outside and go home, Iris and I go to my colleage Ken's wedding dinner. Iris wearing Cheong-sam this time with the balance make-up in the morning, which is very fit the cloth. our foreign colleages request her to kiss them, but today Iris is old enough and know to refuse, shaked her head and goggled at them, listening somethin, though she can't understand. then I am start to think her future life, her boyfriend, who is her Mr.

演出结束后，我们在外面优闲地逛了一阵子就回家了，然后晚上去参加同事KEN的婚礼，小雪这次是穿旗袍去的，带着上午残留的妆，人整个的感觉倒是很符合衣服，婚礼上我们几个老外让她亲亲他们，这次小雪真的长大了，不再傻傻地迎上去让他们亲，这次一听是直摇头抽身就走，要不就瞪着她的大眼睛，很专注地听他们讲什么，虽然什么也听不懂，于是我就忍不住想她的以后，她的男朋友，她的老公会是什么样子的呢？

Along with seawater stress strength upward, the ratio of root to shoot, Na+, Cl- and soluble sugar contents were increased significantly. Under the 10% and 20% seawater treatments, chlorophyll contents have no obvious difference compared with the control, but significantly decreased when the seawater stress further increased. Under the 10% seawater treatments, K+ contents in the shoot and root of Lactuca indica seedlings have no distinct difference compared with the control, but along with seawater stress strength upward, K+ content were markedly decreased by degrees. However, soluble protein content first increased then decreased with seawater concentration augment.

结果表明：苦荬菜幼苗地上部受海水胁迫较为显著，而根在30%海水以内与对照相比没有显著差异；根冠比随着海水比例的增加而提高；10%和20%海水处理下，叶绿素含量与对照相比差异不显著，但随着海水浓度的进一步增加，叶绿素含量显著下降；10%海水处理下，苦荬菜地上部分及根K+含量与对照差异不显著，高于10%海水处理，K+含量随海水比例的增加地上部和根部均逐渐显著降低；海水处理下，体内Na+和Cl-含量逐渐显著增加；地上部可溶性糖逐渐显著增加，而可溶性蛋白呈先升后降。

Differed from the pre-reform period, social rights after Reform were based on a series of intervened contractual relationships rather than identities such as registral citizenship or membership of certain Danwei. From 1980s to 2000s, social rights were mainly based on employment contracts, thus associated welfare entitlement with formal employment, resulting in the lack of social rights of majority members in society.

与改革前社会权利建立在城市人与单位人的身份基础上不同，改革后的社会权利建立在一系列国家干预的契约关系之上。20世纪80年代中期到20世纪末，社会权利主要建立在劳动契约基础上，突出地与城市正规就业相关联，相应地，大部分社会成员缺失社会权利。

This generator adopts PSA transforming absorpion,which uses carbon molecule to separate Oxygen and Nitrogen from air. It transfers compressed air,which is originated from air source, into absovbing untis formed by two tower after oil removing, drying, filtering, purifying of the air. The compessedair generates Nitrogen when it is transformingly absorbed in one tower, then it is sent to another tower for regeneration. It alternately circulates between two towers, which can unceasing achieve 98%-99.9% of pure and cheap Nitrogen..

本设备采用PSA变压吸附原理，利用碳分子筛在压力变化时具有分离空气中氮的能力，以空气为原料，将压缩空气经除油、干燥、过滤等净化处理后，送入双塔组成的吸附组件，压缩空气在一塔内经加压吸附后产生氮气，而另一塔在解吸再生，两塔交替循环，即可不断地得到纯度为98－99.9%的廉价氮气。

A little shamefaced girl lisped,"Mary had a little lamb," etc., performed a compassion-inspiring curtsy , got her meed of applause, and sat down flushed and happy.

一个小女孩脸通红口齿不清地背诵了&玛丽有只小羊羔&等，然后十分认真地行了个屈膝礼。在博得了大家的一阵掌声后，她红着脸，高兴地坐了下来。

I stood in Venice on the Bridge of Sighs, a palace and prison on each hand; I saw from out the wave of her structure's rise, As from the stroke of the enchanter's wand; A thousand years their cloudy wings expand around me, and a dying Glory smiles O'er the far times, when many a subject land Look'd to the winged Lion's marble pines, where Venice sat in state, throned on her hundred isles.

我站在威尼斯的叹息桥上，一边是宫殿，一边是牢房。举目看时，许多建筑物忽地从河里升起，仿佛魔术师挥动魔棍后出现的奇迹。千年的岁月用阴暗的翅膀将我围抱，垂死的荣誉还在向着久远的过去微笑，记得当年多少个藩邦远远地仰望，插翅雄狮之国的许多大理石的高房：威尼斯庄严地坐镇在一百个岛上！
