前齿

10 Months: When the upper and lower anterior teeth grow how to do?

8~10个月：当上下前齿长出怎么做？

The prevalence of root concavity in maxilla, excepted in anterior region, is higher than that of corresponding positional tooth in mandible.

上颚牙齿中除了前齿外，其余牙曲的牙根面凹陷的发生率均较下颚相对位置的牙齿为高。3。

This angle of attack provides the most secure crampon placement, and brings your secondary points closer to the ice.

前齿的入冰角度正确的话能使你更安全，而且紧跟着前齿的立齿正好抵在冰面上。

The job of the guide or alpine climbing instructor is to progressively bring the student to use his feet better and with more precision. The harder grades due to steepness but above all quality of the ice, requires using crampon techniques similar to those used when climbing with rock shoes. The four front points take on a similar importance as it is often necessary to place them rather than kick them.

日益增多的向导和高山攀登教练的任务是让学员们更好更精确的使用好他们的脚，更高的难度级别意味着更加险峻，但首要的是冰的质量，因为它可能需要类似像攀岩鞋一样运用冰爪的技巧，冰爪的四个前齿承担着跟攀岩鞋同样重要的功能，有时候如何放置于好他们比如何踢它们显得更有必要。

Any of various mammals of the order Rodentia, such as a mouse, rat, squirrel, or beaver, characterized by large incisors adapted for gnawing or nibbling.

啮齿目动物：任一种有适于啃或咬的大前齿的啮齿目哺乳动物，如鼠、大家鼠、松鼠或狸

To counter this, move your heel away from your body by rotating the top of your leg inside your hip's ball-and-socket joint.

你的脚和前齿正好可以水来入冰。

Similarly, crampons have evolved as well, allowing them to be used on these types of ice which is quite different from that for which they were traditionally used, for example : kicking straight on with the foot in order for the front points to penetrate.

同样的，冰爪和传统的比起来也有很大的不同，得到了发展使他们能够用于这种地形，例如：带前齿的冰爪使垂直冰面踢冰穿透冰壁成为可能。

Kicking in the typical manner (where your knee joint acts as a hinge) almost always leaves your front points pointing downwards, not straight in.

踢冰的典型动作总是最后让你的前齿是朝下的，而不是垂直于冰面。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
