HR7 is the culmination of four years of bipedal motion research and offers some fundamental improvements over its predecessor.

HR7是对两足动物运动的研究长达四年的最高成果，并且比以前的机器人有了一些基本的改进。

Selecting the optimum carbon sources, nitrogen sources and inorganic salt to get the optimum liquid medium recipe by the orthogonal test in three factors and four levers; Isolated toad gastrocnemius stimulated by pulse electricity was regarded as fatigue model and Clitocybe maxima mycelia was compared with Ringer solution to see what influence they had on muscle contract ability.

采用深层培养方法，筛选出较优的碳源、氮源、无机盐，设计三因素四水平的正交试验，筛选大杯伞的最适培养基；采用脉冲式电流直接刺激蟾蜍离体腓肠肌作为疲劳模型，观察大杯伞菌丝体和任氏液对蟾蜍腓肠肌收缩能力的影响。

Echistatin is a polypeptide with 4pairs of disulfide bridges isolated from Echis carinatus. Its isoelectric point is 8. 3; its molecular weight is 5400kD.

Haimaxuan对四弟说:haha, that was not my problem, someone's fauld, you knew

哈哈，那不是我的问题，是某人的错，你知道的

When 45% methanol solution containing 0.5 mmol/L hexamethylene tetraamine was used as the pump carrier, the pump flow rate and output pressure achieved 0.58 mL/min and 0.79 MPa at 4950 V, respectively. By using the pump carrier as the mobile phase, benzene and naphthanlene were separated on baseline by the EFA system.

在4950 V的外加电压下，以含0.5 mmol/L六亚甲基四胺的45%甲醇溶液为泵载流，电渗泵的流量和输出压强分别为0.58 mL/min和0.79 MPa，以泵载流为流动相，该系统对苯和萘进行了反相色谱分离。

To those, nevertheless, cunning in the stars, it was not unknown that the heavens wore an aspect of ill; and to me, the Greek Oinos, among others, it was evident that now had arrived the alternation of that seven hundred and ninety-fourth year when, at the entrance of Aries, the planet Jupiter is conjoined with the red ring of the terrible Saturnus.

然而，对于那些精通星象的人来说，并非不知道这是天象显出了凶兆；对他们中的我，希腊人奥伊洛斯来说，这显然是木星在白羊宫入口处与可怕的土星那道红色光环交接，七百九十四年的那场大更迭已经来临。

This year, attracts about 3,000 sets of twins, triplets (4) and quadruplets (5) and features contests such as those for the most alike and least alike twins.

今年是在8月3日举行的，吸引了有3000对双胞胎、三胞胎和四胞胎的参与，举办了长得最像和最不像之类的比赛。

The charge control method is: input the battery module and the rectifier transformer to one of the first and second plug base; and using the first voltage detector and the second voltage detector to judge the input voltage of the first and second plug base, so to relatively control the conducting state of the first switch, the second switch, the third switch and the fourth switch, and so to make the rectifier transformer charge the battery module through the control of charge current in the charger.

该充电控制方法，是将电池模块及整流变压器分别输入第一及第二插座其中之一；并由第一及第二电压侦测器判断第一插座及第二插座的输入电压，以相对控制第一开关、第二开关、第三开关及第四开关的导通状态，使整流变压器可经由充电器的充电电流控制对电池模块进行充电。

Bout three months ago my cousin Bud, fourteen year old, was riding through the woods on t'other side of the river, and didn't have no weapon with him, which was blame' foolishness, and in a lonesome place he hears a horse a-coming behind him, and sees old Baldy Shepherdson a-linkin' after him with his gun in his hand and his white hair a-flying in the wind; and 'stead of jumping off and taking to the brush, Bud 'lowed he could outrun him; so they had it, nip and tuck, for five mile or more, the old man a-gaining all the time; so at last Bud seen it warn't any use, so he stopped and faced around so as to have the bullet holes in front, you know, and the old man he rode up and shot him down.

大概三个月前，我的堂兄弟、十四岁的勃特骑着马，穿过河对面的林子。他身边没有带武器，这真是他妈的再傻也没有了。在一处偏僻的地方，他听得身后有马声。一看，是巴第·歇佛逊老头儿，手里拿着枪正飞快赶来，一头白发迎风乱飘。勃特并没有跳下马来，躲到树丛里，反倒让对方赶上来。于是，两人赛开了，一个在前飞奔，一个在后紧追，足足奔了五英里多路，老头儿越追越近。到最后，勃特眼见自己没有希望了，便勒住了马，转过身来，正面朝着人家，于是一枪打进了胸膛。你知道吧，老头儿赶上前来，把他打倒在地。

Do you know, i need you to come back

你知道吗，我需要你回来
