查询词典 obscuration

Due to the coupling of every Zernike circular polynomial in the annular field, the SEIDEL coefficients solved by wavefront fitting with circular polynomial for annular pupils with big central obscuration would have larger errors.

2According to requirement of suppressing stray light in two-mirror system, vertex coordinate formulas of inner baffle are deduced based on geometrograph in the case of certain obscuration, viewing field and vignetting. In order to reduce the obscuration, conical baffle of secondary mirror is ameliorated into a shutter one. Outer baffle is designed when angle of stray light suppressing is foregone and the vanes are designed in C-language program. Finally, the same-height vanes in drawtube between primary and secondary mirrors are designed for further suppressing the stray light in two-mirror system.

The article employs sublation to resurvey the theory of Chinese traditional humanity and then points out: obscuration, superstition and godship and class" limitation are worth being animadverted on and should be abandoned because of contradicting facts; emotion, experience, sociality and civilization should be succeeded and reserved because of being reasonable components; dharma, abstention, harmony and their wide application in practical society and importance should be carried forward. It"s in human social practice and humanity molding process of constant self-denial, self-sublation and self-realization that the new human self-regulation is enriched and then future perspective shown to human beings after sublation.

文章又以扬弃的方式，对中国传统人性理论进行了全面审视，论证并指出：蒙昧性、迷信性、神性和阶级局限性，因为违背了客观事实，所以是值得批判的，应该抛弃；情感性、经验性、社会性和文化性是人性的合理组成部分，应该继承和保留；德性、节制性、和谐性以其在现实社会的广泛应用与作用，应该发扬光大。
