The results show that the system can accomplish asymptotic decoupling of roll angle, sideslip angle and head-on angle for aircraft, and the system is provided with the function for restraining uncertainty in the system. This illustrates that the flight control system designed has not only good decoupling characteristic, but also better robustness.

Besides, the following two features of the book seem to be very incomprehensible: on the one hand, the book includes a full-scale version of Western astrology, not only medical and meteorological one permitted by the Catholic Church, but even natal astrology forbiden by the chruch as well; on the other hand, at the high time when the Tychonic system of calendrical astronomy constructed by Johann Terrenz Schreck (1576-1630), Johann Adam Schall von Bell (1591–1666) and Giacomo Rho (1593－1638) had been contributed by Schall himself to the newly founded Qing dynasty which had officially adopted it immediately, Smogulecki was preaching in the book a system based on Philippe van Lansberge's (1516 – 1632) heliocentric astronomy, and openly claimed that Schall's Tychonic system still committed a number of deficiencies and was outdated, and therefore should be replaced with the Lanbergian system.

另外，该书的两大特点也令人不解：首先，其中包含有完整版本的西方星占学知识，不仅包括天主教会允许的医学和气象星占，而且还包含受教会禁止的生辰星占；其次，在汤若望(Johann Adam Schall von Bell，字道未，1591–1666)等人介绍到中国来的弟谷天文学系统已经被清朝政府正式采纳，传教士的信誉已经微妙地与这种天文学系统紧密地联系在一起的情况下，穆尼阁居然在书中介绍了以哥白尼"日心地动"说为基础的斯伯格(Philippe van Lansberge， 1516 – 1632)天文学，而且还公然宣称，汤若望引进的系统存在许多不足之处，已经过时，应该用兰斯伯格的天文学加以取代。
