But in realistic reason, the absurdity of the personnel system becomes the parent and teachers toward what student bring pressure emollient to borrow;, The family becomes the student to increase the negative important place, it is student the lessons burden aggravate of motive source and direct source, and became student's mental state to increase negative important source;High test conductor's baton BE also result in this phenomenon of important reason, an acceptance score line stopped the teacher's throat, also taking out to beat the student;The slippery 坡 of the occupation morals of teacher make it the mental acceptance ability of the regardless of student and the healthy body of the student, pass to increase student's lessons to make up the shortage on oneself's teaching, this makes some teachers unilateral to emphasize the result but threw to lose the teacher's original intention then;Lack the emollient direct mechanism, foster the teacher and don't go to the character of raise the oneself, don't go to the science skill of raise the teaching, but measures this to breach the method of science in brief to raise the deceitful examination score of student with the enlargement homework, is not science ground passes to raise student's character, raise the teaching result, but use and should try the educational way leading the student copes with the examination with the speculation prosperity method.
而在现实原因中,人事制度的不合理成为家长和教师向学生施加压力的有力借口;,家庭成为了学生增负的重要场所,更是学生课业负担加重的动力来源和直接来源,并且成为了学生心理增负的重要来源;高考指挥棒更是造成这一现象的重要原因,一条录取分数线勒住了教师的喉咙,也抽打着学生;教师职业道德的滑坡使其不顾学生的心理承受能力和学生的身体健康,通过增加学生课业来弥补自己教学上的不足,这便使有些教师片面强调成绩而丢失了教师的初衷;缺乏有力的监督机制,助长了教师不去提高自己的素质,不去提高教学的科学本领,而是用加大作业量这一简单的违反科学的方法来提高学生虚假的考试分数,不是科学地通过提高学生素质,提高教学效果,而是用应试教育的方式指导学生用投机繁荣方法应付考试。

In this paper,a systematic direct perturbation method of dark solitons is found.Having analyzed the mistakes in earlier works on perturbation method for dark solitonsand essence of the direct perturbation method for bright solitons,we notice that to in-troduce the adjoint solutions of the squared Jost solutions and to prove the completenessare crucial to the problem.Giving up the unnecessary scheme of introducing the adjointoperator in the bright soliton case,we directly find the adjoint solutions by meetingthe demand for the orthogonality that inner product of the squared Jost solutions andits adjoint should be proportional to a δ function in the case of continuous spectra.The corresponding adjoint operator is thus found.Taking into account the reductiontransformation,we find a correct description for the completeness of the squared Jostsolutions and directly verify its validity with explicit expressions of the squared Jostsolutions.
本论文建立了系统的暗孤子直接微扰方法,在对前人关于暗孤子微扰方法的错误以及亮孤子直接微扰方法的本质作了充分的分析后,认识到引入平方Jost解的伴随解和证明完备性是问题的关键,撇开过去亮孤子情况首先引入伴随算子的非必要作法,直接从平方Jost解与其伴随解的内积在连续谱时正比于δ函数这一正交性要求出发,找出了伴随解,同时得出了应有的伴随算子,在考虑到约化变换性后,得到了暗孤子情况的平方Jost解的完备性的正确表述,并在单个暗孤子的情况利用平方Jost解的显式直接验证了它的正确性。

The result verifies that the discrete model with power series direct discretization method requires 100 memory length to obtain the better approximation, while one with continued fraction direct discretization method requires only 10 order. Thus the continued fraction direct discretization method is preferable to digital realization of fractional order control algorithms in engineering applications.

Firstly, several kinds of schemes were proposed according to the design demand. The best scheme was chosen after analyzing and comparing the schemes. The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced. The manipulative interface about the kinematics equation direct solution and inverse solution was completed with VC++ and the velocity Jacobian of displacement matrix was constructed using differential transform method. In the process of the trajectory planning based on robot's kinematics analysis, I propone a method by which we can get middle nodal point with normalizing factor in order to simplify our searching for these middle nodal points. In addition, I give these middle nodal points with actual physics signification. For eliminating contradiction between real-time and accuracy, I bring forward separately limit of error and reversal interpolation method. For decreasing calculation quantity, we resort to tri-spline interpolation in the articulation space.We analyse the work range of the robot by resorting to graphic means.
