A new recovery technology of solid waste was made which is from furfuryl alcohol production by furfural hydrogenization. When the solid waste is placed in a vacuum drying box, and is under lower negative pressure and at 130℃, the organic materials in solid waste can be distilled and then returned to the refining workshop to produce qualified furfuraldehyde and furfuryl alcohol. The remainder is mixed with soda ash and roasted in a reverberating furnace. The sodium chromate can be obtained by leaching. Rough cupric oxide is dissolved in nitric acid and cupric nitrate is obtained. A new catalyst was prepared by the above sodium chromate and cupric nitrate and used in furfuryl alcohol production.

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。

By using the above established ELISA,we Examined 35 cases of HSV-1 infected serum and 43 cases of negative serum.The results showed 91.4%of sensitivity,97.6%of specificity,97.0%of positive predictive value,93.3%negative predictive value,accuracy rating 94.5%.

There are no sufficient holes to follow the negative AC bias stress when high frequency is chosen. Due to the operation of the flat panel displays is under AC signal, therefore we discuss the degradation under DC and AC bias stress which include positive and negative bias stress on gate and drain of TFTs. What's more, we discuss asynchronous gate and drain bias stress on TFTs, and study the degradation mechanisms.
