In this research, the activities of CWDE were measured by saccharifying according to the theory that red-brown amino compounds were produced when 3, 5-dinitro salicylic acid and aldehyde were heated together. And the testing conditions were made clear. The activity of Cx should be tested with optimal temperature of 50℃, optimal pH of 4.8, incubation time of 30 min, and optimal substrate of 0.6% CMC-Na. Due to the heat-libality, Cx should be sterilized more than 10 min. The testing conditions of the activity ofβ-G were almost the same with Cx except the substrate of 0.5% salicin and the sterilization time of more than 15 min.

通过对不同初始条件下的CMT排水量进行了分析,发现CMT排水速度主要受CMT内的压力变化的影响:CMT无遮流板排水实验中所有排水量随时间的变化曲线都是单调递增的,都有一个较为明显的拐点,在拐点后,斜率明显增大,说明排水速度增加显著;CMT加遮流板排水实验中排水量曲线的拐点不明显出现时间较无遮流板排水实验要早,说明排水速度增加得较早;CMT加遮流板排水实验如果PRZ初始压力较大,通过改变CMT的初始温度,将会引起排水总量较大的变化;排水速度平衡时间受CMT压力平衡响应时间的影响,较CMT压力平衡响应时间快。

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

The change cannot be explained by a previous personality disorder and should be differentiated from residual schizophrenia and other states of incomplete recovery from an antecedent mental disorder. This disorder is characterized by an excessive dependence on and a demanding attitude towards others; conviction of being changed or stigmatized by the illness, leading to an inability to form and maintain close and confiding personal relationships and to social isolation; passivity, reduced interests, and diminished involvement in leisure activities; persistent complaints of being ill, which may be associated with hypochondriacal claims and illness behaviour; dysphoric or labile mood, not due to the presence of a current mental disorder or antecedent mental disorder with residual affective symptoms; and longstanding problems in social and occupational functioning.
