Accordingly we start from the definition of heterosisH=F1-MP,where H is heterosis, F1 is the first generation offspring, MP is the mean of the parents or midparent, and from the use of a binomial random variable and its extention to the multinomial case derive the basic relations of heterosis with its components.

另一在原文中未加说明的原因是，用配合力概念需要无穷多个品系才能和遗传力的结果相比较，仅此一点就把配合力的作用排斥掉了。文中的主题是杂种优势老大难题可以用笛卡尔的推理方法来解决。

He produced a large quantity of mucic works in his lifetime, included 22 operas, his perfect opera achievement is Le nozze di Figaro, Don Giovanni and Die Zauberflote in his later years, all these master pieces are experienced a long time to create, we have to learn his early opera so that we can know him and his later operas better.

他一生写了大量的音乐作品，其中歌剧就有22部，最为我们熟知的是他后期创作的《费加罗的婚礼》、《唐·璜》和《魔笛》等。为探索莫扎特歌剧的成熟过程，进一步认识和了解莫扎特，更好的把握他歌剧的演唱风格，我们有必要研究他早期的歌剧。

With the Mediterranean Sea so close, fish is a favorite main course. There is haddock, lobster, crab, eel, snapper, mullets, shrimp, and even squid.

由于离地中海很近，鱼是希腊人很喜欢的主菜，有鳕鱼、龙虾、螃蟹、鳗鱼、笛鲷、鲱鲤、虾和鱿鱼。

Aimed at 9-degree of freedom hyper-redundant module robot in intra-vehicular robot system, attention is given to the avoiding joint limits as an optimal mark. Two different iterative algorithms considering fault-tolerance for trajectory planning of redundant robot in Cartesian space are then proposed by using the method of differential locomotion. The first algorithm is for linear-path in which the pose of manipulator can be changed, the second is for circular-path in the plane decided by three noncollinear arbitrary points in the space. Experiments on the specimen robot platform are performed to validate the above algorithms.

以太空舱内机器人系统9-自由度超冗余模块机器人为研究对象，以避关节极限作为优化指标，考虑容错性能，利用微分运动的方法，分别提出了适于计算机迭代计算的冗余机器人在笛卡儿空间进行手爪姿态可变时的直线轨迹优化算法和手爪经过空间中任意不共线3点决定的平面内的圆弧轨迹优化算法。

These fishes all belong to Perciformes, and have become popular for its deliciousness, high value of nutrient and meat quality. The Nibea coibor glue was valuable tonics of the traditional Chinese medicine.

其中浅色黄姑鱼的鳔是名贵的中药补品，千年笛鲷同时也是常见的观赏鱼类，平鲷是港养和网箱养殖的优质鱼类，巨石斑鱼和卵形鲳鲹更是各大酒楼必备的优质食用鱼。

The Spirometer is an excellent complement to the TalkTools Horn and Bubble Hierarchies which target phonatory control and abdominal grading.

Descartes suggested that the pineal gland is "the seat of the soul" for several reasons.

笛卡尔提出松果腺是&灵魂的场所&，有几个方面的原因。

In so doing, we will be setting aside concerns discussed by Anthony Brueckner (1994b) and Stewart Cohen (1998c) that skeptical arguments might instead rest upon a different epistemic principle entirely, what they term an "underdetermination" principle.2 Relatedly, we will also be taking a very modern Cartesian understanding of the skeptical argument for granted, and therefore ignoring the emergence of renewed interest in classical Pyrrhonian skeptical arguments by such figures as Williams (1988b) and Robert Fogelin (1994).3 Finally, attention will be confined to those anti-skeptical theories of knowledge which are genuinely capable (given, of course, that they are correct) of meeting the skeptical challenge.

在这样做的时候，我们会把有些有关系的讨论放到一边，例如Anthony Brueckner (1994b)和 Stewart Cohen (1998c)所指出的怀疑论论证可以依赖于不同的认识论原则，他们称为&不确定性原则『&underdetermination& principle』&。[2]相关的，我们也会承认对怀疑论论证的笛卡尔式理解，因此忽略了出现的对古典Pyrrhonian怀疑论论证的重新关注，例如Williams (1988b)和 Robert Fogelin (1994)。[3]最后，也不会去关注这样的反怀疑论理论，这些真正能够和怀疑论挑战交锋。

So there is a disanalogy between the rain skeptic's successful reply and the Cartesian skeptic's rebuttable reply.

因此，在下雨怀疑论者的成功回应和笛卡儿怀疑论者的回应之间是不可类比的。

In seeking a firm philosophical basis on which to rest his scientific theories, Descartes succeeded in developing the first coherent sketch of a recognizably modern philosophical outlook.

在寻求坚实的哲学基础上了他的科学理论，笛卡儿成功开发了第一个连贯的示意图公认现代哲学观。
