Carthlicum, and was located on region of wheat chromosome 2AL near the gene Pm4b, it maybe either Pm4b, or a new gene linked to Pm4b. Temporarily, the gene was designated as PmPS5A.

通过与含有已知抗病基因品种或品系的对该20个菌株反应模式比较和系谱分析，推测Am9／莱州953*〓 F〓含有Pm4b，波斯小麦PS5含有Pm4b与一个未知抗病基因组合；（DR147／Ae14）／／莱州953*〓 F〓和硬粒小麦DR147含有Pm4a和一个未知抗病基因组合；尾状山羊草Ae14和小伞山羊草Y39含有新的抗白粉病基因。

We found that it is the effect of odd-order term of f which describe the total energy collocation between forward wave and backward wave that causes the difference of modulation instability between normal dispersion region and abnormal dispersion region.

第三，根据增益谱的比较，我们从色散关系式中看到了产生这种变化的原因。正是由于存在f奇次项的影响而导致了这种在正常色散区和反常色散区变化趋势的不同。

The observational and calculated results are well matched. The calculated mean diameter, mean square-root diameter, mean cube -root diameter and liquid water content are all well matched with the observational results; In the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region. It is found that F-100, 2dc, and 2dp's particle concentrations increase in leeward region, but rising extent is different, which is likely to be due to difference of seeding effect time.

拟合值和观测值吻合的较好，计算出的平均直径、均方根直径、均立方根直径和粒子浓度与观测值也比较吻合；本文对两组个例的催化影响区域及可能采集到相应值的下风方区域进行了分析，催化下风向影响区的F-100、2DC、2DP的粒子浓度比背景值都有所增加，但是增加的幅度不同，应该是催化响应时间的原因。

Therefore the dispersion curves obtained in the field are primarily consisted of the first mode. For a heterogeneous elastic solid consisting of three homogeneous layers whose interlayer has low velocity, the phase velocity V〓 of the first mode will also close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, but V〓 of the first mode will close up to the shear wave velocity of the interlayer when f→∞, and there is a cut-off frequency at high frequency region for the first mode and V〓 close up to the compressional velocity of interlayer when interlayer is liquid.

当三层固体介质中存在软夹层时，若f→OHz，则其基阶模式的相速度V〓→V〓（V〓为最底层介质的瑞利波速度）；若f→∞，其基阶模式V〓→V〓（V〓为中间层介质的横波速度）；若三层介质中存在液体夹层，当f→OHz时，基阶模式V〓→V〓，而基阶模式在高频段存在一个截止频率，截止频率处的瑞利波速度V〓→V〓；由此可判定，野外实测的相速度频散曲线不仅有基阶导波模式，同时还应有高阶导波模式波的存在，接收信号中存在模式间的跳跃，因此频散曲线会产生"之"字形现象。

Then I played with the F-Stop and Focus Region Scale till I found a DOF result I liked.

In chapter 4, by AREELS, the Generalized Oscillator Strength Density Spectra were measured in the energy region from 56 to 66eV, with the incident energy 2. 5 keV and energy resolution 80 meV, at scattering angles from 0°to 6°, corresponding to the momentum transfer K〓=0.03~2. 01 a. u. The Fano profile parameters f〓 and q for the optically allowed transition 〓(0, 1)〓P°and the optically forbidden transitions 〓(1, 0)〓S〓and 〓(1, 0)〓D〓 were obtained as a function of K〓. With the hyperspherical coordinate wavefunctions, the dynamical correlation are discussed qualitatively. So, a new experimental way to study dynamical electron correlation effect is opened.In chapter 5, the widely used R-matrix theory was introduced. Then, the GOSDS for the optically allowed excitation series (1s〓)〓S〓→〓(0, 1)〓P°(n=2-4) were calculated by this method, and the Fano profile parameters f〓 and q were obtained sequently. So the electron correlation effect can be described by these parameters quantitatively, and the theoretical results were compared with our AREELS experimental results.

在第四章中，实验上，同样使用角分辨的高能量分辨快电子能量损失谱仪，在2.5keV电子入射能量和80meV的能量分辨下，测量了0°到6°散射角下的He原子双电子激发态在56~66eV的广义振子强度密度谱，这种情况，0°~6°对应的动量转移范围K〓=0.03~2.01a.u。，得到了光学允许跃迁的双电子激发态〓（0，1）〓P〓和光学禁戒跃迁的双电子激发态〓（1，0）〓S〓、〓（1，0）〓D〓的Fano线形参数f〓，q等随动量转移变化的曲线；观测到了几个强度很弱、能级很窄的光学允许和禁戒跃迁双电子激发态，用前人准确的理论结果进行了标识；通过比较弱共振〓（1，0）〓S〓和〓（-1，0）〓S〓的强度随动量转移K〓的变化规律，结合超球坐标理论计算的波函数，定性地阐述了在电子碰撞散射过程中它们各自不同的动力学电子关联效应，发展了一套在实验上研究电子关联效应的新方法。

Dielectric, piezoelectric and electrmechanical coupling properties of PZT and PSZT systems at high Zr content region were studied. The feature of high Kt and low Kp of PZT-based materials near F-AF phase boundary was exploited and examined, and electromachanical coupling anisotropy Kt/Kp is higher than that at the morphotropic phase boundary , Kt≥0.40, Kt/Kp≥3. 0. This phenomenon can be realized by electric field -induced AF-F phase transition and explained by coupling effect of two-sublattice in antiferroelectric unit cell.

The EFM results show that the Fω and F2ω force mappings on disk-like GaN islands can be well-resolved. The intensities of the electric forces Fω and F2ω on the region of GaN islands are comparatively lower as respect to that of the plane surface. The higher the island is, the lower the value of intensity is.
