The difficulty in statistical inference using Bayesian approach is calculating the posterior margin distribution, in most situations, it is very difficult to do so and even the formula can not be got.

运用Bayes 统计分析的方法进行统计推断的难点在于其后验边际分布的计算，在很多情况下很难，甚至不可能得到后验边际分布的解析表示，有时虽然可能得到解析表示但是结果相当复杂，不便于应用和推广。

My next Work was to view the Country, and seek a proper Place for my Habitation, and where to stow my Goods to secure them from whatever might happen; where I was I yet knew not, whether on the Continent or on an Island, whether inhabited or not inhabited, whether in Danger of wild Beasts or not: There was a Hill not above a Mile from me, which rose up very steep and high, and which seem'd to over-top some other Hills which lay as in a Ridge from it northward; I took out one of the fowling Pieces, and one of the Pistols, and an Horn of Powder, and thus arm'd I travell'd for Discovery up to the Top of that Hill, where after I had with great Labour and Difficulty got to the Top, I saw my Fate to my great Affliction, viz.

接下来我得观察一下周围的地形，找个合适的地方安置我的住所和贮藏东西，以防发生意外。至今我还不知自己身处何地，在大陆上呢，还是在小岛上，有人烟的地方呢，还是没有人烟的地方，有野兽呢，还是没有野兽。离我不到一英里的地方，有一座小山，高高耸立于北面的山丘之上，看来那是一道山脉。我拿了一支鸟枪、一支手枪和一角筒火药，向那座山的山顶走去。历尽艰辛，总算爬上了山顶；环顾四周，不禁令我悲伤万分。

A new brushless DC motor DTC scheme was studied to solve those problems associated with direct torque controlof brushless DC motor,such as difficulty to control flux and complexity to estimate torque.The flux hysteresis controller was ignored in the constant torque region and an improved method was proposed to make the estimation of torque easier.The proper stator voltage space vector was selected based on the output of the torque hysteresis controller and the sector which the current rotor flux locates in.

摘 要：针对无刷直流电机直接转矩控制中磁链观测困难、控制复杂等问题，提出了一种应用于无刷直流电机二二导通方式下的新型直接转矩控制方法：在电机基频以下调速时，略去了常规的磁链观测控制环节，改进了转矩计算方法，通过转矩滞环控制选择所施加的空间电压矢量。

The inner toruses represent the nodes at the upper level and the outer toruses represent the nodes at the lower level, which overcomes to some extent the difficulty that the hierarchy expand in the longitudinal direction is not proportionable to that in the latitudinal direction.

CTT通过将层次结构的节点映射到一组同心圆环上，内层圆环表示上层节点，外层圆环表示下层节点，在一定程度上克服了层次结构在横向和纵向扩展的不成比例，并且节点之间的父子关系和兄弟关系都实现了有效的可视化。

BACKGROUND: Nowadays positive pressure ventilation has been widely applied in breath prostrating and other diseases of lung. But its disadvantages, such as pneumonia relating to breathing machine, abnormally low blood pressure and difficulty in removing breathing machine, bring risks for patients while supplying breathing function.

摘要背景：目前正压通气技术广泛应用于呼吸衰竭等肺部疾病的治疗，但由于正压通气也存在着诸如呼吸机相关肺炎、低血压和撤机困难等弊病，使得该技术在实现呼吸维持功能的同时也给患者带来了更严重的生命威胁。
