Methods; 45 patients with pancreatic cancer were treated with HIFU for 262 person-times.Before treating,these patients have first taken a Chinese herbal acting as strengthening the body resistance to eliminate pathogenic factors,reliving the depressed liver,sooting the liver and regulating the circulation of qi,promoting digestion and digestant for 3～4 days.In 262 person-times,74 person-times were adopted GI decompression,5～10 minutes before operation 26 person-times ware adopted simple fast,6 person-times were additionally taken airless water,and 156 person-times were additionally taken ultrasonic developer-aid for the use of GI examination.

方法； 胰腺癌患者45例，共行HIFU治疗262次，治疗前先服用扶正祛邪、疏肝理气、消食化积的中草药3～4天，采用胃肠减压者74例次，术前单纯禁食者26例次，禁食后术前5～10min加服脱气水者6例次，加服胃肠检查用超声助显剂156例次。

In the fourth chapter, we discussion the characterization of admissible in the general linear model under equality constraint and inequality constraint, we give the necessary and sufficient condition that homogeneous linear estimator is admissible estimator, and by using the relationship between homogeneous and inhomogeneous linear estimator, we obtain the characterization of admissible inhomogeneous linear estimator.

第四章分别在带等式约束条件以及不等式约束条件下，讨论了一般线性模型线性估计的可容许性特征，给出了在约束条件下齐次线性估计为可容许估计的充分必要条件，同时利用齐次线性估计与非齐次线性估计之间的关系，把齐次线性估计的可容许性特征推广到了非齐次线性估计的可容许性特征。

We know that the solutions of quadratic, cubic and quartic can be expressed by radicals. As to the solution of the quintic which has became an issue for past two or three hundred years, it was not solved until 1832 a great young Mathematician of French named Galois who recommended group theory that proved a polynomial of degree 5 and over 5 can't be solvable by radicals.

中文摘要我们知道二次、三次及四次的方程式都可以用根式表示，至於五次方程式的解迟迟无法解决，这个问题持续了两三百年，直到1832年，一位法国青年Galois在其决斗前夕，在他的遗书中，这位伟大的青年数学家引进了群的理论，证明了：五次及五次以上的方程式，不可能有公式解。

The model is usually an inhomogeneous system of linear equations. It is pointed out that the general solution of the homogeneous system of linear equations can satisfy the request of making the wires tight, and the special solution of the inhomogeneous system of linear equations are not smaller than zero, so their sum is greater than a given mumble.

由于多自由度绳牵引并联机构的静力学模型一般是一个非齐次线性方程组，本文指出可让对应齐次方程组的通解的最小值满足绳保持张紧的条件；让非齐次线性方程组的特解非负，而避免利用对应齐次线性方程组的通解保证非齐次线性方程组的解不小于给定的最小值。

Establish integrated invertibility theory over it: By R〓R〓 transformation method, we solve the problem of deciding weakly invertibility and finding weak inverse, By founding the bijections between all quadratic form automata and input memory linear finite automata, we find a algorithm to produce all weak inverse quadratic form finite automata.

本文着眼于这些最基本问题，将有限域上的二次型和置换多项式理论引入有限自动机可逆性的研究，构造了一类由二次型构成的非线性有限自动机（3.6定义），称之为二次型有限自动机，我们在其上面建立了与线性有限自动机可逆性理论相对应的完整的可逆性理论：采用线性R〓R〓变换方法，解决了此类有限自动机的弱可逆性判定、求弱逆问题（3.10、3.12定理）、通过建立全体二次型有限自动机与全体输入存储线性有限自动机之间的保持弱逆性的一一对应，给出了产生全部可逆二次型有限自动机的方法。

When he heard the sound of gunfire then get down to 20 gallons of liquor, a stove spade, a Huoqian, two Tonghu, Tongguo and Grill when the shuttle is in Cluj read "Bible" when , Seems to be the wizard finish spell want the same thing as a coincidence of magic, here is novel in this second stage of reference to "Bible", here is Kru shuttle by a gift of God, when the third novel to And "Bible", in Cluj shuttle by the threat of terrorism and disease, the precarious life of the time, it seems that the author of a demon Satan for a guest, is the Kru people of the shuttle Buxiao the "original sin" Another penalty, or is he received the last of God's gift to God and not the consequences of Thanksgiving, when he is determined to be more devout starting point, this echoes the "Bible" in the words "in trouble when you call for me I will Laijiu you, and you have to praise me,"Mingmingzhizhong Defoe who arranged a deal with the integrity of God, but Kru shuttle in this transaction in the integrity of performance is not very good, so in God Pre-paid to the equivalent of his wealth, its very credibility of not giving a penalty.

当他听到炮声随后顺着枪声得到二十加仑地酒、一把火炉铲、一把火钳、两个铜壶、铜锅和烤架的时候，正是克鲁梭在读《圣经》的时候，好像精灵念完咒语得到想得到的东西一样巧合一样具有魔力，这里是小说在这一阶段第二次提及《圣经》，这里便是克鲁梭得到的上帝的馈赠，当小说第三次提及《圣经》时，是在克鲁梭受到恐怖和疾病的威胁，性命岌岌可危的时候，好像是作者安排的一场恶魔撒旦的一次客串，是克鲁梭为人子而不孝的"原罪"的又一次惩罚，抑或是他得到上次上帝的馈赠而对上帝感恩不够的后果，此时也是他下决心会更加虔诚的起点，这便呼应了《圣经》里的话"在你患难时呼唤我，我就会来救你，而你要赞美我"，冥冥之中笛福安排了一次人与上帝的诚信交易，但是克鲁梭在这次交易中表现的诚信不是很充分，所以在上帝预先付给他那些等价财富后，对其的不很诚信给予了惩罚。
