In the tread compound tests showed that with the reduced amount of softener, tread rubber hardness increase in the formula for the 7:00 performance tables are in line with national standards tread compound, in the formula Add a renewable 10 ordinary plastic tensile strength, elongation at break are not GB request, and add 10 high-performance renewable plastic, also reached the performance tread compound GB requirements, and easy Compound and the time is short, and other process performance is also very good, adding 10 HPRR than not joining the compound reduced costs 0.73 yuan / Kg.

在轮胎胎面胶试验中表明，随软化剂用量减少，胎面胶硬度增加，在配方为表七时各项性能均符合轮胎胎面胶国家标准，在该配方中添加了10份普通再生胶拉伸强度、扯断伸长率都达不到国标要求，而添加10份高性能再生胶，各项性能亦达到轮胎胎面胶国标要求，并且炼胶易、时间短、其他工艺性能也大好，添加10份HPRR比没加入的胶料成本降低了0.73元/Kg。

Real time PCR was undertaken to quantitate the AQPs gene mRNA expression.

本文的研究目的为： 1判定AQPs基因是否在羊胎肺中表达以及在其胎肺发育中的表达模式； 2确定AQPs基因在羊肺中的表达分布； 3研究在引起胎肺液体动力改变的生理模型中胎肺AQPs基因表达的变化。

Ovary superior, of 2 or 3(–5) carpels, usually 1-loculed or incompletely 2–5-loculed; ovules numerous, anatropous; placentation parietal, axile, or basilar.

子房上位，心皮2者3(-5)，通常1室或不完全2-5室；胚珠多数，倒生；胎座式为周壁胎座，轴胎座或者基底胎座。

Results There was a downtrend in weight of dams on GD20 as the DBTD exposure dose increased. The weight of dam's utero significantly decreased in 30 mg/kg group. A significant decrease in fetal weights was observed in all DBTD groups, and fetal sizes in 20, 30 mg/kg groups. Exposure to DBTD from GD 12-19 resulted in a distinct increase in normalized anogenital distances in female fetuses, but no effects were seen in male ones.

结果 妊娠20d时，孕鼠体重随DBTD剂量升高呈下降趋势，但与对照组比较，差异无统计学意义，30mg/kg组孕鼠子宫重量显著降低；所有DBTD染毒组雄性、雌性胎鼠体重均显著降低，20、30m/kg组胎鼠体长显著降低；所有DBTB染毒组雌性胎鼠肛门距生殖器的标化距离显著增长，而雄性胎鼠无显著变化。

Different genotypes were determined in Luxi monotocous cows, Luxi twinning cows, Chinese Simmental cows, Angus cows and Simmental×Mongolia cows by restriction fragment length polymorphism. The value of polymorphism information content indicated that this was a moderate polymorphism in Luxi monotocous cows and Luxi twinning cows.

运用PCR-RFLP法验证并分析该位点在鲁西牛双胎群体和单胎群体及中国西门塔尔牛、安格斯牛和西蒙杂交牛单胎群体间的多态性，结果表明，在鲁西牛双胎和单胎群体中分布A、B两个等位基因，处于中度多态。

In the progenitive capabilities of clean KM,the second fetuse is the is the best,then descend step by step after the th ird fetuse.

其繁殖性能以第2胎最好，第3胎次之，从第3胎开始，逐胎下降，第6胎最差，已不适用在屏障系统内大规模生产繁殖。

The first-born, second-born and third-born breeding sows were separated to be fed, after that they were artificially fecundated. The progeny swinery of the first-born and more than the second-born breeding sows were separated to be fed and the annual production litter size and pathological change of local pneumonia for breeding sows etc.

方法］将头胎、二胎、三胎母猪分开饲养后进行人工授精，并将一胎母猪后代猪群与二胎以上母猪后代猪群实行隔离饲养，记录每头母猪年产仔数和地方性肺炎病变等数据。

The tire cord fabric layer is provided with an edge wound around the core of the bead, and the wound part is provide with a base part and a radial outer part, wherein, the base part extends towards to the axial outer side from the inner side of the core of the bead along the core of the bead; and the radial outer part extends towards to inner side axially on the radial outer side of the core of the bead.

胎体帘布层具有绕胎圈芯缠绕的边缘，使得缠绕部分具有基部和径向外部，基部沿着胎圈芯从胎圈芯的轴向内侧延伸至其轴向外侧，并且径向外部在胎圈芯的径向外侧上轴向朝内延伸。

Although clad diamond prevent iron family elements from eroding diamond and improve the strength between matrix and diamond, there still are many problems in applying Fe-base formulae. After the adding amount of reinforced elements is determined, the effect of the basic elements of matrix on its comprehensive performance is studied. The results show that while wc content is 15%. Fe/Ni 1: 1, 663-Cu etc 50%, Sintering temperature 920℃, temperature kept time 1. 5 mintues, matrix comprehensive preformance is best.

尽管金刚石表面镀膜隔绝了铁族元素对金刚石的侵蚀和提高了胎体对金刚石的粘结强度，但以Fe代Co还存在胎体的综合机械性能等问题，本文试着从材料学的强化理论出发确定了微量元素的添加量之后，用正交试验设计方法研究了胎体的基本组元WC、Fe/Ni、663—Cu的加入量及烧结工艺对胎体综合机械性能的影响，得出在WC15%，Fe/Ni1：1，663—Cu等其它为50%，烧结温度920℃，保温时间为1.5分时胎体的综合机械性能最优。

In June, for example, a group of Norwegian researchers released a study showing that firstborns are generally smarter than any siblings who come along later, enjoying on average a three-point IQ advantage over the next eldest—probably a result of the intellectual boost that comes from mentoring younger siblings and helping them in day-to-day tasks.

和第二胎相比第一胎孩子的平均智力商数要高三分。这也许是因为第一胎孩子对较年轻的弟弟妹妹们进行辅导教育，帮助他们完成每天任务中取得了智力提高的缘故。而第二胎又要比第三胎智商数高一分。

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）。
