The puppy thinks that it is a fun game. When it fi nds the rag, it gets praise and a reward like a dog biscuit or time to play with its favourite ball. The hiding places keeps getting harder all the time. If the puppy does something wrong, it isnt punished. But it also doesnt get any praise or reward that it would like to have.

小狗一定觉得这是一种好玩的游戏，当它找到这块布，它就会得到诸如一块饼干或玩球一类的奖励，掩藏地点的难度越来越大，如果小狗错了，虽不会受罚，但得不到它期望的任何奖赏。

I had a great feeling with the fans, they were lifted when I went on a dribble.

对球迷，我有一种很深的感觉，每次我带球他们都会心动。

Methods: The course of the infection was observed for 20 weeks. Spleen cells from mice infected with Echinococcus granulosus were collected in different period, CD4+ and CD8+ cell levels were determined by flow cytometre.

对感染细粒棘球蚴的昆明种小鼠观察20周，在不同时间取脾制备细胞悬液，用流式细胞术检测CD4+、CD8+淋巴细胞的百分率。

A method based on optimal bounding ellipsoid algorithmic procedure at each stage of updating is presented.

通过在不同的更新阶段采用优化定界椭球算法，对该系统提出了一种新的状态估计方法。

Milk fat globule epidermal growth factor factor 8 (MFG-E8) is a protein that binds to apoptotic cells by recognizing phosphatidylserine and that enhances the engulfment of apoptotic cells by macrophages.

乳脂肪球上皮生长因子因子8(MFG-E8)是一种通过识别磷脂酰丝氨酸结合凋亡细胞的蛋白，这可以提高巨噬细胞对凋亡细胞的吞噬。

This paper de-duces the equation of scroll case surface with the enveloping theory,builds the envelope sur-face of ellipsoides with variable radius by using the the method of constructing an ellipse withseveral arcs and presents a new and simple method fOr geometry moulding of scroll case sur-face.

蜗壳是水电站的重要部件之一，本文以包络理论推导了蜗壳曲面方程；并采用分段圆弧构造椭圆的方法构造了变径椭球包络曲面，为蜗壳曲面的几何造型提出了一种新的简便方法。
