Thus, evaluation of the minimum zone circle could be solved effectively.Three methods of assessment of roundness error were proposed in this dissertation. Based on the criteria of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle and convex hull, a unified approach was proposed to evaluate roundness error of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle. Evaluation of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle was fulfilled with rotation based the contact pattern. The minimum circumscribed circle and maximum inscribed circle were evaluated with curvature and the curvature circle.

Maintain deflector if the size of the same voltage, the voltage change is accelerating, we can see a very accelerated voltage reduce, electron beam deflection angle instead of increasing, it is because of low accelerating voltage, the electron velocity smaller horizontal direction, electronic deflection plates in the field of the role of the extended time, the angle of deflection increases .
如果保持偏转板的电压大小不变,改变加速极的电压,可以看到加速极的电压减小,则电子束偏转的角度反而增大,这是因为加速极电压低,则电子的水平方向速度变小,电子在偏转板中受电场力作用的时间加长,所以偏转的角度增大。

The tectonic rocks along the fault zone are composed of cataclastic rocks and mylonites formed in higher, middle and lower temperature. Respectively, both of structural features and rocks have the features of multiple phase's of deformation. The deformation features of main minerals in the high temperature mylonites show that: the quartz has the form of long single crystal and the fabric feature of point maximum near X axis; the feldspar has the form of recrystallization assemblage, They present a high amphibolite-granulite facies with temperature >600℃ and depth >20km. The deformation features of mylonites formed in middle temperature show that: the quartz has the form of polycrystal banding and the fabric feature of point maximum near Y axis and small circle girdle with Y rotational axis; the feldspar has the form of a coremantle structure, They reflect a high greenschist-lower amphibolite facies with temperature from 400℃ to 600℃ and depth from 15km to 20km.

The increased amount of non--exchangeable NH4^+-N during the incubation indicated as the following tendency, namely, Eum-Orthic Anthrosols 〉 Los - Orthic Entisols 〉 Hap-Ustic Isohumisols 〉 Ust-Sandiic Entisols. Organic material influenced significantly the increased amount of non-exchangeable NH4^+-N (P was 0.0002, 0.0004 and 0.0003 when incubated at 20 d, 50 d and 60 d, respectively). NH4^+-N increased remarkably when Stlpa bungeana and Medicago sativa were added compared with no addition. The contents of non-exchangeable NH4^+-N increased significantly when added (NH4)2SO4 compared without addition at 20 d, 40 d and 60d of incubation and P was 0.0037, 0.0033 and 0.0027, respectively. It was the result that the NH4^+-N from (NH4)2 SO4 was fixed within the soil. The increased amount of non-exchangeable NH4^+-N increased significantly for different soils, on which different vegetation types grew before the collection of soil samples, when incubated at 20 d (P=0.0434), but not significantly at 40 d and 60d (P=0.7378 and 0.5375). The increased amount of non-exchangeable NH4^+-N in the soil, on which crop straw and nitrogen fertilizer had been incorporated for a long-term period, was larger than that of no addition, but it was not significantly different among these two fertilization models. Soil clay, total N and organic matter were positively correlated remarkably with the contents of non-exchangeable NH4^+-N, the increased amount of non-exchangeable NH4^+-N had no correlation with soil clay, whereas it had significantly positive correlation with total N and organic matter.
培养期间非交换性NH4^+-N的增加量均表现为以土垫旱耕人为土最大,其次是黄土正常新成土,简育干润均腐土和干湿砂质新成土较小;添加有机物料极显著影响培养期间的非交换性NH4^+-N增加量(培养20d、40d和60d时P分别为0.0002,0.004和0.0003),表现为紫花苜蓿和长芒草土壤非交换性NH4^+-N的增加量均极显著高于不添加有机物料的对照土壤;在培养20d、40d和60d时,加(NH4)2SO4土样非交换性NH4^+-N的增加量显著大于不加(NH4)2SO4土样(户分别为0.0037,0.0033和0.0027),这是土壤对(NH4)2SO4中NH4^+-N固定的必然结果;不同植被类型土壤培养20d时的非交换性NH4^+-N增加量差异显著(P=0.0434),培养40d和60d时差异不显著(p分别为0.7378和0.5375);长期秸秆和氮肥配施土壤非交换性NH4^+-N增加量大于不施肥对照土壤,但差异不显著土壤黏粒、全氮和有机质与培养0d、20d、40d和60d时土壤的非交换性NH4^+-N含量均呈极显著正相关;而非交换性NH4^+-N的增加量与粘粒无相关性,但与全氛和有机质呈显著正相关。

The possible reason is that doped Zr〓 ion enters the interstitial sites for its small ionic radius and no dipole complexes were formed. Monovalent ion F〓 has been reported to improve the scintillating performance greatly. Our results show that Agrand diagrams of F〓: PWO crystals obey an modified Cole-Cole equation. The crystals present similar dielectric relaxation phenomena to but have much higher activation energy than that of RE〓: PWO crystals, which originate from the 〓 dipole complexes. The co-doping of trivalent Y〓 and pentavalent ion Nb〓 does not always show a better scintillation performance than that of solely doped samples, which could be attributed to the existence of the 〓 dipole complexes, which counteract the solely doping effect.
而Zr〓由于离子半径太小,可能进入间隙位置,不形成类似的偶极缺陷;一价负离子F〓的掺入提高了晶体闪烁性能,阻抗谱测试结果表明F〓:PWO晶体Argand图符合修正的Cole—Cole方程,晶体同样表现出介电弛豫现象,并具有比RE〓:PWO晶体中高得多的弛豫激活能,可能起源于形成的〓偶极缺陷;Y〓和Nb〓双掺的PWO晶体并没有显示出两种离子单掺优点的叠加,阻抗谱测量结果表明,在双掺晶体中可能形成〓偶极缺陷,使两者掺杂作用相互抵消。
