种球

While the yo-yo today is a toy for kids,it didn't start out that way.

尽管今天悠悠球是孩子们的一种玩具，但最初它可不是用来玩的。

In this study,a simple method for preparation and characterization of three calcium zincate samples of different morphology was developed to improve the high-rate charge/discharge performance of zinc negative. The samples were synthesized,followed by direct reaction method and ball milling method.

为提高锌负极大倍率充放电的性能，先以直接反应法和球磨法合成了四边形、六边形和不规则三种形态的锌酸钙，并用X射线衍射光谱法和扫描电子显微镜法对其进行了表征，然后以恒电流充放电法考察了三者作为负极添加剂时对锌镍电池大倍率充放电性能的影响。

The low temperature biofilm was composed of physchrotrophs, Through the experiments of isolation and identification, 8 strains of physchrotrophs were obtained from biofilm, they are Comamonas、Flavobacterium、Arthrobacter、Bacillus、Micrococcus、Pseudomonas、Achromobacter and Vibrio.

低温生物膜的活性主要来自其上面的低温微生物，分离鉴定试验结果表明，组成低温生物膜的微生物主要有8种，发现它们分别属于丛毛单胞菌属、黄杆菌属、节杆菌属、芽孢杆菌属、微球菌属、假单胞杆菌属、无色菌属和弧菌属。

But I think that specially when I have played in other positions, I know I do not possess Aimer's skill, but I do have a complex approach and according to my position on the field, I score quite a lot of goals.

但是我觉得尤其在我踢其他位置的时候，（我知道我没有艾玛尔的技术可我确实有一种复杂的方法，）依据我在场上的位置，我进了不少的球。

The"antegrade"manner of fenestration, adopted to enhance the success rate of experimental balloon fenestration, has never been mentioned in the previous literatures, and will provide an alternative means for clinical treatment in the future.

为提高实验性球囊开窗术的成功率而设计的&顺行&开窗方式，在以往文献中未见报道，为今后的临床治疗提供了一种可供选择的方法。

Methods By using Raten Nephelometry method,the serum α 1 Antitrypsin were detected from some nomal persons and some patients with any kinds of liver disease,especially those PHC patients with AFP negativity.

-抗胰蛋白酶(α1 -Antitrypsin，α1 -AT)，是具有蛋白酶抑制作用的一种急性时相反应蛋白，分子量为 5 。4万，在醋酸纤维薄膜或琼脂电泳中位α1 -球蛋白区，主要由肝脏合成。

A very specialized feeding adaptation in zooplankton is that of the tadpolelike appendicularian who lives in a walnut-sizedballoon of mucus equipped with filters that capture and concentrate phytoplankton.

浮游动物体内一种极特殊的进食适应性变化是蝌蚪状的尾海鞘纲动物的那种适应性变化，而尾海鞘纲动物则存活於核桃大小的黏液球囊内，装备有过滤器，用以捕捉和集中浮游植物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
