The effects of strain rate on plastic formation and dynamic recrystallization of 7050 aluminum alloy were discussed. The results show that the deformation of the specimen is inhomogeneous, and the effective strain in the center of the specimen is maximum. The deformation inhomogeneity increases with the increase of strain rate. The effective stress of specimen is inhomogeneous. As the strain rate increases, the minimum stress value moves from the drum-shaped region to the heart of specimen. The standard deviation of dynamic recrystallization grain size decreases with the increase of strain rate.

模拟结果表明，热变形过程中，试样的各个部位的变形分布不均匀，心部的等效应变最大，变形的不均匀性随应变速率的增大而增大，但是变化的程度不大；试样内部各部位的应力大小分布不均匀，随应变速率的增大，最小应力值由自由变形的鼓形区域逐步向心部移动；动态再结晶晶粒尺寸标准偏差随应变速率的增加而减小。

Allosteric enzymes possess an allosteric site in addition to their ACTIVE SITE.

别构酶控制着别构部位和它的活性部位。

In addition,allosteric enzymes may be controlled by effector molecules that bind to a site other than the active site and alter the rate of enzyme activity.

此外，变构酶可被效应分子所控制，它结合的部位并不是活性部位，却改变酶的活性。

The results showed that the order of the feather-moulting of chick was starting from wing to tail, breast sides, huckles, back and waist, cervix, abdomen, breast, calfs, head, abdomen sides.

结果］母雏鸡各部位绒毛开始脱换的顺序为：翼部→尾部→胸部两侧→大腿部→背腰部→颈部→腹部正下方→胸部正下方→小腿部→头部→腹部两侧，各部位绒毛结束脱换的顺序为：尾部→翼部→胸部两侧→大腿部→背腰部→腹部正下方→颈部→小腿部→头部→腹部两侧→胸部正下方。

It is indicated that the easily cavitated locations are at the top of orifice, the comer at downstream of orifice and the center of the backflow.

结果显示，容易发生空化的部位主要有三处：一是孔板顶缘处，二是孔板下游角隅处，三是孔板下游回流旋涡中心部位。

The activity of neutral invertase in leaves was higher than other parts, and stolon was ascended, whereas new corm was ascended firstly then descended. The activities of Q-enzyme increased except leaves. The activities of amylase ascended first then descended. The activities of Q-enzyme and amylase in the new corms and cormels were higher than in the leaves and stolons.

叶片中性转化酶活性较其他部位高，匍匐茎不断增加，新球是先增加后降低。Q酶活性除了叶片外，其他部位均不断增加；总淀粉酶活性变化趋势均是先增加后降低。

Cysticercus ellulosae could live in liver not only in muscle as we thought before. During the fast process of sending pigs to go into the market, it should be aware that even though cysticerci are not found in liver, they may be still in suitable locations of muscles, and more attention should be paid to pig quarantine.

猪囊尾蚴除在四肢肌肉等主要寄生部位生长外，还可以在猪的肝脏内寄生，但是随感染时间增加会逐渐死亡和钙化，表明在当前生猪快速出栏养殖过程中，猪肝脏无囊尾蚴寄生时，其余主要寄生部位如四肢和驱干肌肉内仍有囊尾蚴寄生，提示在生猪检验检疫工作中应予以重视。

Also, humans appear to have picked up more than 200 genes from bacteria and another 50 from strange segments of DNA called transposable dements that "jump" during early development from one place, to another within the genome.

其二，人类似乎接纳了细菌的200多个基因：还接纳了其他50个奇异的DNA片段，它们是发育早期阶段在基因组内从一个部位&跳&向另一个部位的可移动片段。

The density of the foot 、middle part and top are 124grain /m~2、91 grain /m~2、66 grain /m~2,the seeds is more little windward than the leeward.The density of seed banks in windward is 81grain/m~2 and the leeward density is 100grain/m~2.The seed of ephemerals bourgeoning reaches the pinnacle on April and May.The diversity of different parts sand dune is different,but the differences do not reach the marked level.The similarity is high between the seed banks and the vegetation.

迎风坡种子库密度比背风坡面少，迎风坡种子库平均密度为81粒/m2，而背风坡种子库平均密度为100粒/m2；短命植物种子在4月上旬达到萌发高峰，沙丘不同部位物种多样性存在差异，土壤种子库和地上植被存在较高的相似性，此外短命植物在沙丘不同部位的分布存在较高的空间异质性。

The simulation results show that the asymmetry structure of the ratchet die cavity influences the BMG's flowing behavior greatly. During the material filling tooth cavity, dead zone volumes exist and situate on the areas with sparse teeth distribution. The full filling or not of the ratchet tooth tips, as the final filling region of the forming process, determines the super-plastic forming quality. Adopting smaller punch speed or longer load holding time is necessary for full filling of the tooth tips.

研究结果表明，棘轮模腔结构的不对称性对材料的流动行为影响显著；在材料向齿形的充填过程中存在流动死区，死区的位置处于齿形分布较稀疏的部位；齿形尖角是成形的最后充填部位，在终成形阶段采用较小的压下速度或较长的保压时间，有利于齿形尖角的完全充满。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
