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。

Results The relationship between case numbers? temperature and the hours of solar radiation is negative correlation and is positive correlation with air-pressure in winter .

结果 冠心病月发病人数及冬季各旬发病人数与温度、日照时数呈负相关，与气压呈正相关；秋季发病人数与气温呈负相关，春夏两季则不明显。

In Chapter 3, a comprehensive analysis of the coupling coefficients between plane waves in conventional dielectric media and Bloch waves in photonic crystals with effective negative refractions is performed by the layer-KKR method.

第三章，我们运用layer-KKR方法计算得到平面波与半无限负折射光子晶体中Bloch波的耦合效率，从而可以将介质-等效负折射率光子晶体的透射率与介质-负折射率介质的透射率进行系统的比较。

The intensity-dependent interaction of the different states:the superposition of thebinomial states,generalized binomial states,hypergeometric states,Polya states,negative binomialstates,the superpositions of the negative binomial states,Glauber-Laehs states,displaced binomialstates and displaced negative binomial states with two-level atoms are studied and the dynamicsof the atomic population inversion and the field second-order correlation function areinvestigated.

对各种量子态：二项式叠加态，广义二项式态，超几何态，玻利亚态，负二项式态，负二项式叠加态，Glauber-Lach态，位移二项式态，位移负二项式态与二能级原子在强度耦合情况下的相互作用中原子与光场的动力学特性做了仔细的研究。

They have many strange properties such as negative phase velocity, negative refractive index, perfect imaging, inverse Doppler effect and abnormal Cerenkov radiation.

负折射率介质最早由前苏联科学家Veselago在20世纪60年代从理论上提出来的，是一种具有介电常数ε和磁导率μ同时为负值的介质，它具有诸如负相位速度，负折射率，理想成像，逆Doppler频移及反常的Cerenkon辐射等多种奇异的物理现象。

The strongly negative correlation between winter sea-ice extent of Davis Strait and July rainfall of North China turns into weaker correlation.

冬季戴维斯海峡海冰面积与华北夏季及7、8月降水年际关系有明显的年代际变化特征：其与夏季总降水的年际关系由1974年前较好的负相关在1974年后变差，与7月降水的年际关系由1974年前较好的负相关在1974年后变弱，与8月降水的年际关系由1974年前较好的负相关在1974年后变差；另一方面，其与中国160站夏季及7、8月降水的年际关系在1974年前后发生变化的主要特征是：与夏季总降水、7月、8月降水的年际关系由1974年前的相关系数分布呈&东西型&变为1974年后相关系数分布呈&-+-&的&南北型&。
