3M i τi = 2 a i bi 3M i k = Ga i b i3 由后一式得 Gka i b i3 Mi = 3 60 Also Gk M =∑Mi = 3 i a i bi3 ∑ So we have: M a i b i3 = M 3 ∑ a ibi i Consequently we have:τ 3 Mb i = a i b i3 ∑ 3M k = G ∑ a i b i3 It is noticeable that: the shear stress of the midpoint of the long side of the narrow rectangle is considerably precise.

而 故有 Gk M =∑Mi = 3 M i a i bi3 ∑ a i b i3 = M 3 ∑ a ibi 从而有τ i 3 Mb i = a i b i3 ∑ 3M G ∑ a i b i3 k =值得注意的是：由上述公式给出的狭矩形长边中点的剪应力已相当精确，然而，由于应力集中的存在，两个狭矩形的连接处，可能存在远大于此的局部剪应力。

The single a machine that should design to adopt serieses MCS-51s primarily conduct and actions main a measurement for, passing spreading feeling machine to the current of air measuring, its change is homologous pulse signal, this pulse signal through A/ D conversion with D/ A conversion after produce the certain electric voltage signal, will show the inceptive pulse signal a discharge for representing to come out at the same time.

该设计主要采用了MCS-51系列的单片机作为主要的芯片，通过传感器对燃气流量的测定，将其转变为相应的脉冲信号，这个脉冲信号经过A/D转换和D/A转化之后产生一定的电压信号，同时会将起初的脉冲信号所代表的流量显示出来。

It takes advantages of AR-quiver analysis and APR- tilting translation. We proved: if T_A is a tilting A-module over a path algebra of type A_n or a characteristic tilting A-module over a path algebra of type D_n,E_6,E_7, E_8,then there are points corresponding indecomposable direct summands of T_A in theτ- orbit of each edge.

Thirty patients (M 23, F 7; age 50 a±s 15 a) with chronic eczema were treated with etofesalamide ointment (given th inly on the surface 3 times daily) for 4 wk; Another 30 patients (M 24, F 6; age 44 a±14 a) were treated with ointment base (given thinly on the surface 3 tim es daily) for 4 wk.

60例慢性湿疹病人，30例(男性23例，女性7例；年龄50 a±s 15 a)用乙氧苯柳胺软膏均匀涂布患处，tid， 4 wk为一个疗程；另30例(男性24例，女性6例，年龄44 a±14 a)采用乙氧苯柳胺软膏基质均匀涂敷患处，tid， 4 wk为一个疗程。

We first analyze the relationship between the characteris-tic subspaces of linear transformation A,and its conjuge transformation A*, on then-dimensional complex inner product space Cn, and prove that the characteristicsubspace of an enginvalueλof A is orthogonal to that of enginvalue μ of A* if λ≠μ.

首先，分析n-维复内积空间Cn上的线性变换A与其共轭变换A*的特征子空间之间的关系，证明出只要A的一个特征值λ与A*的一个特征值μ的共轭不同，那么它们对应的特征子空间是正交的。

For different polynomials g, if the characteristic polynomial of a n matrix A is irreducible, then we get some theorems to determine matrix equations g =A solvable; if it is reducible, then, to see n-dimension space vectors M over a field F as F-module, we use module theory to determine these equations solvable such that it is simpler and clearer to investigate these questions.

对于不同多项式g，当n阶矩阵A的特征多项式为不可约的，我们给出了矩阵方程g=A有解的判定定理；当A的特征多项式为可约的，把域F上的n维线性空间M作为由A导出的F -模，我们利用模论知识来决定矩阵方程g=A有解性，从而使这一问题变了简单，研究思路更加清晰。

It is shown from the analysis results that the average retrogradation rate of the south coastline of the Laizhou Bay during 1958 to 2004 was 27 m/a,the average retreating rate of the 0 m isobath was in the range of 27 to 65 m/a,and the average cutting rate of beach face was 2.1 cm/a.
