The proportion of freedom to necessity is decreased or increased, according to the point of view from which the act is regarded; but there always remains an inverse ratio between them. A drowning man clutching at another and drowning him, or a hungry mother starved by suckling her baby and stealing food, or a man trained to discipline who at the word of command kills a defenceless man, all seem less guilty—that is, less free and more subject to the law of necessity to one who knows the circumstances in which they are placed, and more free to one who did not know that the man was himself drowning, that the mother was starving, that the soldier was on duty, and so on.

一个先足落水的人，抓住另一个人，那人也要淹死了；或者，一个因为哺育婴儿而疲惫不堪的、饥饿的母亲，偷了一些食物；或者，一个养成遵守纪律习惯的人，在服役期间，遵照长官命令，杀掉一个不能自卫的人——在知道那些人所处的条件的人看来，似乎罪过比较小，也就是自由比较小，属于必然性法则的成分比较多；而在不知道那个人自己就要淹死、那个母亲在挨饿、那个士兵在服役等等的人看来，自由就比较多。

Which is based on the proposed RBF neural network inverse controller and a proportion differential controller.

并提出一种基于RBF神经网络逆控制与比例微分控制相结合的双模控制策略。

Both of the ESD were proportional to kVp 2.2 to kVp 2.5 and were linear proportion to mAs. Inverse square law exists in the relationship of focus-film distance, FFD, and ESD. The impacts of field size and patient thickness to ESD are negligible. Optimized operating condition is chosen to improve the diagnosis rate and to reduce the patient dose. The ESD, 0.12±0.06 mGy, performing the optimized operating condition of chest x-ray examinations, is less than both values of reference doses recommended by NRPB and IAEA.

研究结果发现，入射表面剂量随操作条件而变，以相同的条件照射，三相位X光机所造成表面剂量大约是单相位X光机的1.9倍；入射表面剂量与kVp的2.2至2.5次方成比例，与mAs约成线性正比，与焦斑至底片距离的关系大约符合平方反比定律；照野面积及身体厚度虽会影响表面剂量的大小，但其程度远低於kVp及mAs的影响。

With the increase of the proportion and degree of difficulty of the tunnel project in the whole highway construction, in geotechnical questions, especially with the improvement of big mechanized and automatic construction technology, the new geotechnical questions have appeared , are changed into moving simulation dynamically from the mechanics problem of classical rock, in order to solve these new problem, this paper proposes the studies of the displacement inverse analyses and fuzzily classifies and the surround rock intelligently and predict out of shape greyly.

随着隧道工程在整个公路建设中的比重和难度的增大，在现代岩土工程问题中，特别是随着大机械化和自动化施工技术的提高，出现了新的岩土工程问题，由经典岩石力学问题转变为动态挠动模拟，为了解决这一新问题，本文提出位移反分析模糊分类及围岩变形智能化灰色预测研究。

The results show that the flow length of microfluid in micro channels that have different section shapes but the same length(50 mm) is in inverse proportion to sections RPA (RPA means the ratio of the section s perimeter to its area),and the smaller the RPA , the longer the flow length.

研究结果表明：微流体在截面形态不同，长度均为50 mm微流道中的流动长度与流道截面的比表面积(截面周长与截面面积的比值)呈反比关系，比表面积越小，流动长度越大；当微流道的比表面积较小时，熔体温度与注射压力对流动长度的影响较大；当比表面积较大时，熔体温度与注射压力对流动长度的影响较小，且不论比表面积如何变化，注射压力对流动长度的影响比熔体温度对流动长度的影响显著。

the phenomena that students' mathematics grade polarizes in the junior period is more serious than that of the elementary period, the inverse proportion of the poor students is bigger, especially in the grade two of the junior high school, it is much more serious.

初中阶段学生数学学习成绩两极分化呈现出比小学阶段更严重的趋势，后进生所占的比例较大，特别在初中二年级表现得尤为明显。
