That is why some hydrophobic ingredients should be added in order to made floating tablet with ideal floating duration other than decreasing the tableting pressure alone.According to the eroding kinetics, the floating tablet made of HPMC with greater viscosity as K100 MCR and K15 MCR is better than that made of HPMC E 15 LV. The erosion of the tablet made of HPMC E 15LV followed the first order kinetics. 20% of the tablet eroded with 4 hours which is 22 times that of the tablet made of HPMC K 100 MCR. The fast erosion of the tablet made of HPMC E15 LV led to quick buoyancy decrease. The quick swelling of floating tablet made of CMC-Na led to quicker water uptake.

溶蚀动力学表明，以高粘度HPMC K100MCR和K15 MCR制备的漂浮片，其漂浮性能要优于低粘度的HPMC如E15-LV，后者的溶蚀符合一级动力学规律，4小时内片面溶蚀达20％，溶蚀速度比前者大22倍，由于速度太快，漂浮制剂的漂浮力因此会迅速降低；高分子材料CMC-Na制备的漂浮片，虽然遇水后迅速膨胀使体积增大，但是，由于水渗入的速度大于体积膨胀的速度，因此不能产生足够的浮力和维持理想的持续浮力，另外，这种材料制备的漂浮片的溶蚀速度太快，4小时内片面溶蚀达30％，漂浮制剂的漂浮力也因此会迅速降低。

It truncates the Born scattering serial to the first order term which bring divergence. The image perturbations must be linearized to the same order.

高阶部分的丢失必然带来巨大的截断误差，因此剩余成像必须也进行线性化，以适应大速度扰动和大延拓步长。

The experimental results indicates that the optimum pH range was 1.60~2.20, and the optimum H2O2 concentration was 10.0 mmol/L. The degradation ratio increased with the increasing concentration of ammonium ferric oxalate in the range from 0.1 to 1.0 mmol/L, but no significant increase in degradation ratio was observed when the concentration was above 1.0 mmol/L. When the concentration of fuchsin basic increased, the degradation ratio dropped, while the concentration of degraded fuchsin basic rised. When the concentration of fuchsin basic was low, the degradation followed first-order kinetics, but when it was high, the degradation could be fitted by zero-order kinetics. The absorbtion of fuchsin basic at 543 nm disappeared quickly, while the absorbtion of intermediates formed during the course of fuchsin basic dagradation at 298 nm vanished slowly.

试验结果表明：碱性品红降解的最佳初始pH为1.60~2.20，最佳初始H2O2浓度为10.0mmol/L；草酸高铁铵的浓度在0.1~1.0mmol/L时，碱性品红的降解率随浓度的增大而增大；高于1.0mmol/L时，则降解率相差不大；碱性品红的初始浓度增大，降解率减小，而实际降解的浓度则增加；碱性品红的浓度在低和高时，降解动力学过程不一致；随降解的进行，碱性品红在可见光区的吸收峰迅速消失，而降解过程中形成的中间产物吸收峰却消失很慢。

The paper design start point with a four-group the paraxial lens set with two groups lens of movements, among the first order and three order aberration is ignored. The imprimis acquisition optical zoom focal length start the structure.

本文的初始的设计以四群组成二群移动的理想透镜组，其中不考虑一阶及三阶象差，首先取得光学变焦的初始结构。

The second-order post-Newtonian(2PX) equations of light ray have to be discussed under the recent extension of the DSX scheme which was founded in early 1990's to discuss a complete first-order post-Newtonian celestial mechanics for N arbitrarily composed and shaped, rotating deformable bodies.

DSX体系是在20世纪90年代初建立的，用来讨论对N个任意形状和组成、自转可变形物体的一套完整的一阶后牛顿(1PN)天体力学理论。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
