LI Feng-smart, studious, progress, speed, and soon they learned a lot Caidan and Huadan drama, such as "Yang, like crying like" The Concubine Yang,"sweep spend three drunk" and He Xiangu,"off Liuyang off" Mrs. Lee,"trouble learning" lady's maid,"Chai-chuan big fan" of the history of Bi-tao,"Jade Hairpin" Chen Miao-Chang,"Tibet Boat" Wu Fei-xia,"siskin mind" in secluded mother,"Xiu Ru Ji" in Li Xian,"Beating Surface-cylinder "of the bloom," play "Chui Mei Niang," parrot "Regardless of the fat, and" Hess "," strange pairs would,"" fighting knife into the House,"" together with beads,"" Plaster Rock Hill ","Dream,""Roar in mind" and so on.

李凤云聪明好学，进步极速，不久便学会了很多彩旦和花旦戏，如《仰像哭像》的杨贵妃、《扫花三醉》的何仙姑、《折柳阳关》的李夫人、《闹学》的春香、《钗钏大番》的史碧桃、《玉簪记》的陈妙常、《藏舟》的邬飞霞、《金雀记》的幽娘、《绣襦记》的李亚仙、《打面缸》的腊梅、《踢球》的翠美娘、《学舌》的胖姑，以及《思凡》、《奇双会》、《打刀入府》、《合珠配》、《膏石山》、《惊梦》、《狮吼记》等。

The feeble fingers were never idle,and one of her pleasures was to make little things for the school children daily passing to and fro, to drop a pair of mittens from her window for a pair of purple hands, a needlebook for some small mother of many dolls, penwipers for young penmen toiling through forests of pothooks, scrapbooks for picture-loving eyes, and all manner of pleasant devices,till the reluctant climbers of the ladder of learning found their way strewn with flower, as it were, and came to regard the gentle giver as a sort of fairy godmother, who sat above there, and showered down gifts miraculously suited to their tastes and needs.

她那虚弱的手指从未有闲着，她的乐事之一便是为每天从屋旁经过的学童们制作小东西－－在窗口放一双手套，这是为冻紫的手准备的；放个针线包，给某位拥有许多玩具娃娃的小母亲；放一些拭笔布，给那些在歪七竖八的笔划丛林里辛勤劳作的小书法家们；放一些剪贴薄，给那些喜欢画画的孩子们；还有各种各样令人愉快的小玩意，直到那些极不情愿攀登学问阶梯的孩子们发现，他们前进的道路上布满了鲜花。这时他们把那亲切的馈赠者看作是童话中的仙女。她坐在那上边的屋子里，给他们抛投各种奇迹般契合他们品味和需要的礼物。

ST depression in transmural ischaemia was generated with ST elevation and was an integral part of the current source.

利用心肌的双域模型计算机模拟了不同区域心肌透壁缺血时ST 段位移在心脏表面的分布，发现心脏表面ST 段位移的分布式样和缺血区域大小有关，一个小面积的透壁缺血在缺血区上出现均匀分布的ST 段上升，而在心脏表面的其他部位上几乎没有出现ST 段下降；一个大面积的缺血像左降支或左旋支区域的缺血， ST 段位移在心脏表面的左侧区出现了一个偶极子式的分布，在缺血区为ST 段上升，在正常区为ST 段下降，并且其幅度随远离缺血边界而减小；同时发现透壁缺血时的ST 段下降是缺血电流源的不可分割的一部分。

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.

碱基含量分析可知，序列的G C含量(49.3％)＜A T含量(50.7％)，密码子第三位点的G、T含量都有较强的偏倚性；序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次)，C→A、T→G颠换数均为2次，其余颠换模式均未发生；转换数明显高于颠换数，Ts／Tv=9.5～19，密码子第三位点的转换数最高，呈现了相当强烈的转换偏倚性；密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239，表明密码子第一位点的替换速率变异最大，第二位点次之，第三位点的替换速率变异相对较小；编码同一氨基酸的同义密码子并非随机使用，表现出一定程度的使用偏倚性；同义替换速率和非同义替换速率分别为0.0787和0.0011，dS与dN值间的差异极显著(Z=4.713，p＜0.01)，而ω=0.0284，明显小于0.3，表明雁属鹅细胞色素b基因序列经历了中度净化选择作用；单步非同义替换(Sing-step nonsymonymous codon substitution，SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同；构建的最大简约树与邻接树拓扑结构一致，支持中国家鹅的双起源学说，即除伊犁鹅外的其它中国鹅品种起源于鸿雁，伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。

In the present study, we collected cumulus cells oocyte complex from ovaries of two different strain mice. The cumulusenclosed oocytes were cultured for 6 h in MEM supplemented with growth factor and FSH. The meiotic maturation of these oocytes has progressed to pro-metaphse Ⅰ stage and the condensed chromosomes are visible under DIC microscope, metaphase Ⅰ spindle even can be detected under Polscope. The metaphase Ⅰ spindles of oocytes were exchanged under such microscopes. After electric stimuli, 91. 6% and 91. 6% karyoplasts-cytoplasm pairs were fused respectively. The resulting oocytes were cultured further in MEM and over 80% of oocytes released the first polar body. 79% and 77% of oocytes formed two pronuclei after in vitro fertilization and the embryos were cultured in KSOM supplemented with amino acids. Over 60% of embryos developed to blastocyst stage.

在本研究中我们在取得两种不同品系小鼠的卵丘卵母细胞复合体后，先将卵丘卵母细胞复合体置于含有多种生长因子和激素的MEM培养液中培养6小时，此时卵母细胞已进入第一次减数分裂的前中期，并且在DIC倒置显微镜下可以看到浓缩的染色体，用Polscope可以发现明显的纺锤体，借助这种显微镜通过显微操作将两种不同品系小鼠来源的卵母细胞的MI纺锤体进行互换，经过三次直流电脉冲作用后，分别有91.6％的胞质—MI核质体对融合，经过进一步的培养后，超过80％的重组卵母细胞排出第一极体，体外受精后分别有79％和77％的重组卵形成双原核，受精后的胚胎在KSOM胚胎培养液中体外培养4天后，超过60％的胚胎发育至囊胚。

In the pace of issuing the New Generation 911 Targa in no time, Porsche located in Stuttgart started to upgrade 911 Series in unprecedented high speed. These two power units directly adopt fuel injection technology to make quality and economical efficiency improved. Instead of using Tiptronic S self-changing gearbox, Porsche Doppelkupplungwith shifted gears in blistering speed is used. And PTM--Porsche Traction Management is the substitution for 4 wheel drive system.

随着新一代911 Targa的即将推出，位于德国斯图加特的保时捷正在以前所未有的高速度完成911车系的更新换代：两款新动力单元采用直接燃油喷射技术，使新车型的性能和经济性都得到了改善，换档极快的Porsche Doppelkupplung保时捷双离合器变速箱取代了选装的Tiptronic S自动变速箱，电子控制保时捷牵引力控制管理系统取代了以前的四轮驱动系统。

To take one especially spectacular example: A traditional paisley pattern was embroidered on the sleeves of a coat, then it trailed off down the leg of the matching trousers before reappearing on the lapels of a suit and the shoulders of a sweater (which also featured a leopard-print collar). Here's another illustration: Sheeshedar, the mirrored Indian fabric you've seen in markets since time immemorial (or at least since hippies crossed the landmass from Asia to America), was used to make a pair of trousers—and matching shoes. Then it was teamed up with a poncho that could have been sliced from shaggy white yak wool. Just perfect for the backstage area of a Led Zeppelin reunion concert, but curiously incongruous for a McQueen fashion moment. Perhaps that was the problem with this show.

最明显的表现部分就是：古波斯国的传统涡纹花呢被设计师运用细腻精致的刺绣织造手法，展露在外套的袖口、西装长裤的小腿肚、西装外套的翻领、以及毛衣的双肩部份，（还有美洲豹皮纹也被添加在领口处）；同时，镜面反射般的立体明暗光泽也被McQueen加强在成套的裤装/鞋款上，那种神秘的异国光泽，年代攸远似乎已不可考，但早期曾在嬉皮年代被一些摇滚乐手从印度辗转传至美洲和英国；不过可惜像是南美风格的白色堥牛毛poncho披风，却被评为，似乎适合Led Zeppelin演唱会后台的歌迷们穿著、而极不搭调在McQueen的fashion how现场。
