The hour hand: the circle of a clock face is divided by 12 hours, so each hour is 1/12 of the circle, and since a circle is 360 degrees, each hour is 360/12 degrees, so the angle of the hour hand is calculated this way, but as you all have noticed, no analog clock's hour hand stands still exactly on the current hour number until an hour is passed.

时针：在时钟面圆除以12小时，所以每个小时的1 / 12圈，由于圆是360度，每一个小时是十二分之三百六度，所以时针的角度这种方式计算，但大家都已经注意到，没有模拟时钟的时针上的立场仍有当前小时一个小时，直到完全通过。

As object lessons to explain: 1 the nature and habits of oviparous animals, the possibility of aerial flight, certain abnormalities of vision, the secular process of imbalsamation: 2 the principle of the pendulum, exemplified in bob, wheelgear and regulator, the translation in terms of human or social regulation of the various positions of clockwise moveable indicators on an unmoving dial, the exactitude of the recurrence per hour of an instant in each hour when the longer and the shorter indicator were at the same angle of inclination, videlicet , 5 5/11 minutes past each hour per hour in arithmetical progression.

297他把它们作为实物教材，用以说明：（1）卵生动物的本性与习性，空中飞行的可能性，一种异常的视觉器官，世俗界用防腐药物保存尸体的方式。（2）体现于摆锤、齿轮与整时器上的钟摆的原理；不动的针盘上那可移动的正转的长短指针在各个位置作为人或社会规范所包含的意义；长针和短针每小时在同一倾斜度相遇的那一瞬间，也就是说，按照算术级数，每小时超过5 5/11分的那一瞬间，每小时重复一次的精确性。

Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.

本研究目的在於改变长晶时间的长短，合成出同径大小的Li-Al LDHs，再经由改质剂sulphanilic acid sodium salt hydrate将Li-Al LDHs无机层材表面有机官能化制备出改质型Li-Al LDHs-SAS，於是进一步藉由扫描式电子显微镜、射径仪和穿透式电子显微镜等仪器分别观察LDHs改质前和改质后其主层结构型态上的变化；从中可以发现Li-Al LDHs随著长晶时间的增加其径有随之增大的趋势，但经有机化改质后其径会由於改质环境的影响明显低许多，针对此现象本实验将未改质和改质后之Li-Al人工无机层材制备成复材进一步探讨其在热性质和难燃特性上的为表现。
