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。

B The necessity of such light is evident from what has been said, for faith is essentially an act of assent, and just as assent to a series of deductive or inductive reasonings, or to intuition of first principles, would be impossible without the light of reason, so, too assent to a supernatural truth would be inconceivable without a supernatural strengthening of the natural light Quid est enim fides nisi credere quod non vides?

As the beginning of this thesis, the important meanings of sea ice to global climate change and ocean engineering in polar and subpolar sea regions are explained firstly. Then, it is pointed out that sea ice numerical modelling, as a powerful tool of sea ice research, is limited by the precision of parameters within models instead of itself so far. It is meaningful to study the important parameters of sea ice dynamics by means of the rapidly developing digital imaging techniques so as to provide better input parameters needed in numerical models.

文中首先阐述了海冰对全球气候变化和极区、亚极区海域海洋工程问题的重要性，并指出作为海冰研究重要手段之一的海冰数值模拟发展到目前，其准确性更加受到海冰参数而非模式本身的限制，因此以目前快速发展的数字图像技术为工具对海冰动力学过程中的重要参数进行研究，以提供数值模式所需要的高精度和准确性的数据，是非常有必要的。

非物理方式的一个问题在于无法反馈受力给人体，但由于我们采用的人体实例数据为捕获的真实数据，无论是否反馈都不能改变人体的运动，'所以即使使用物理方式计算出对人体的反馈力，也是不必要的。

One reason is that some lees well-known nutrients and some nonnutrient food components could be important to health;some foods may be better sources of these than others .another reason is that monotonous diet may deliver large amounts of toxins or contaminants .each such undesirable item in a food is diluted by all the other foods eaten again.

原因有以下几点：其一是有的鲜为人知的营养素或非营养素成份实际上对健康及其重要。一些食物可能比其他食品含有相对较多的此类物质。另一个原因是单一的膳食可能含有大量的毒素或者污染物质。每一种食物中含有的不必要的成分可以被搭配的其他食品稀释，如果这种食品要几天后才再吃，那就会被进一步稀释。

Instead, as in all areas of medicine, physicians need to tailor therapy to patients' specific needs. For ADHD patients who have a history of substance abuse, for example, the treating psychiatrist may want to start treatment with a nonstimulant therapy. If the treatment is not adequate, the second choice would be a long-acting stimulant coupled with rigorous monitoring."Because the stimulants used to treat ADHD are controlled substances, there is built-in monitoring," Dr. Alder said."However, we can watch such patients with extra care for warning signs such as early refills."

另外，Alder医师表示，所有的治疗都一样，医师们必须要对患者的特定需求，量身订制一套治疗法；对於有药物滥用纪录的ADHD患者，举例而言，医师们可以先使用非兴奋剂作治疗，若不合适，第二个选择就是长效型的兴奋剂，再辅以密集的监控；因为用以治疗ADHD的性奋剂都属於管制药物，所以都会有著必要的监控要求；无论如何，我们还是可以从患者的一些徵兆看出，如提早作药物补充等迹象。

The therapy of protection of liver function is very necessary: diammonium glycyrrhizinate can recover the non-specific damage of liver cells, Fufangdanshen can improve the microcirculation of liver, and tiopronin and reduced glutathione has the unique function to recover liver damage caused by fat invasion. Of 168 cases, 60 cases (35.7%) show exacerbation of liver function after using fat-reducing drugs for 1-2 weeks. Of 41 cases (male 36 and female 5) with the complication DM2, 58.5%(24/41) of cases also show exacerbation of liver function after using sugar-reducing drugs.
