Equidistance point and difference theory in theory of function approximation are studied. Meanwhile, the relation among difference, difference quotient and derivate is revealed. By drawing Lagrange's and Cauchy's theorem of mean on difference and Taylor's formula into difference function, four theorems, such as Lagrange's theorem of mean on difference, are concluded in simple way. On the basis of these conclusions, the asymptotic property of middle point is studied, a series of new conclusions are drawn and the discussions on the asymptotic property of middle point in differential mid-value are summarized.

Bias, two random teachers score the prompts. It's on a scale of 1 to 4. Ifyou got a 1 you were completely off topic and made no sense. A 2 wassomeone who was sort of headed the right way, but did something that hurtthe entire paper. A 3 meant you were on topic, but there were someinconsistencies that kept it from being perfect. A 4 paper was anorganized, powerful, and well-delivered paper with little or no mistakes.

如果你得1分，就是说你完全离题，文理不通；2分的话呢，就是虽然没跑题，但某一些方面伤害了整篇文章；3分就意味着&文已对题&，但还有些地方与中心不够一致，还达不到完美的地步；4分就是结构完整，论述有力，表达清晰的，但有一点点小纰漏或者根本没有问题的文章。

It seemed that I would write something that was so beautiful that it couldn't possibly get anything but the best grade, but I always end up with mediocre grades. For the sake of avoiding bias, two random teachers score the prompts. It's on a scale of 1 to 4. If you got a 1 you were completely off topic and made no sense. A 2 was someone who was sort of headed the right way, but did something that hurt the entire paper. A 3 meant you were on topic, but there were some inconsistencies that kept it from being perfect. A 4 paper was an organized, powerful, and well-delivered paper with little or no mistakes.

In this study, six campaigns around Anping tide gauge, Tainan, were successfully performed and the collected GPS buoy data were processed with four types of precise ephemeris provided by IGS, including final product, rapid product, ultra-rapid product and ultra-rapid product with the use of PPP technique. Comparing the PPP results with DGPS, the differences reach 3~5 cm in the horizontal and 10 cm in the vertical with final product; 6~8 cm in the horizontal and 15 cm in the vertical with rapid product; 15~20 cm in the horizontal and 30~40 cm in the vertical with ultra-rapid product; 2~3 m in the horizontal and 3~4 m in the vertical with ultra-rapid product. In addition, the collected data were also processed by DGPS techniques using different reference stations to analyze the effect of various baselines. The results show that accuracy degrades when the baselines increase.
