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 anatomical variation of uteruses in each group was observed, we found that the uteruses in group A had a pink color, and the shape of them seemed like a string of beads, congestions didn't existed in this group; the other four groups were all aborted to different extents, the color of uteruses in group B, D, E were purple black, embryos were small than the ones in group A, or the uteruses had a bamboo-shaped figuration, all embryos were aborted, uterine cavity had congestions, vagina also had bleeding situation; the color of uteruses in group C was incarnadine, some of the embryos had been eliminated, vagina had a slight extent bleeding.

观察各组妊娠大鼠子宫颜色及出血情况， A组胎粉红，呈串珠状，宫内未见瘀血； B、C、D、E组均出现不同程度的流产状，B、D、E组胚胎紫黑，较A组变小，或子宫呈竹节状，胚胎消失，宫腔瘀血，阴道出血；C组胚胎深红，部分胚胎消失，阴道少量出血，C组妊娠结果优于B、D、E组。2。

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.

通过对Dynkin型路代数的AR-箭图分析及利用APR-倾斜变换，证明了A_n型路代数倾斜模及D_n，E_6，E_7，E_8型路代数本性倾斜模T_A的一个必要条件是，在A的AR-箭图Γ_A的边缘的r-轨道都有T_A的不可分解直和项对应的点。

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.

结果表明，1958-1984年，莱州湾南岸岸线平均侵蚀后退速率为27 m/a，0 m等深线后退速率为27~65 m/a，岸滩平均蚀低速率为2.1 cm/a.1984-2004年，莱州湾南岸岸线位置基本无变化，岸滩平均蚀低速率为1.04 cm/a，水深5 m以浅的区域表层沉积物变粗。
