I take the official oath to-day with no mental reservations and with no purpose to construe the Constitution or laws by any hypercritical rules; and while I do not choose now to specify particular acts of Congress as proper to be enforced, I do suggest that it will be much safer for all, both in official and private stations, to conform to and abide by all those acts which stand unrepealed than to violate any of them trusting to find impunity in having them held to be unconstitutional.

今天我庄严宣誓，既无保留意见，也不用苛求的尺度去分析宪法或法律。我现在不能做这样的选择：国会的某些特别法案要去彻底实施。但我做一个建议，不论是正式和私下场合上，配合和服从还未撤消的所有法令会更为安全，不要指望违背宪法而触犯其中一项会不受惩处。

The nonwoven mess of polyglycolic acid coated with polylactic acid is extensively used as scaffolds in tissue engineering, but its hydrophobic charateristic and weak adsorptivity to cells limit its application.

以PLA包埋的PGA无纺网是应用较为广泛的支架之一。但其亲水性差，对细胞吸附力弱，是其不足之处。此实验选择了卵磷脂和多聚赖氨酸来分别和共同包埋PGA＋PLA，来观察其亲水性和对细胞吸附力的改变，及对细胞功能的影响。

The beam quality of a LD pumped Nd∶YAG laser is measured with CCD camera system. The background characteristics of the CCD system and the influence of the size of integral box upon measurement results are investigated. The following conclusions can be derived form experimental results:(1) Background is strongly depend upon exposure time and pixel binning,while temperature has an ignorable effect upon it,whether with or without ambient light.(2) A 5%-cut is the minimum value in order to get a reasonable result.

采用CCD系统实验测量了LD泵浦Nd∶YAG激光器的光束质量参数，研究了CCD系统的背景噪声特性和积分区域选取对光束质量参数测量的影响，从实验数据中得到以下结论：（1）在有、无背景光两种条件下，背景记数强烈地依赖于曝光时间和像素的合并，温度影响可以忽略不计，（2）为获得M2合理的测量结果，至少要选择5%积分区域。
