A study of phase morphology of PBT/POE-g-MAH/nano-CaCO3 composite by means of scanning electron microscopy showed that the domains size of nano-CaCO3 capsulated by POE-g-MAH elastomer in composite when PBT was mixed directly with POE-g-MAH and nano-CaCO3 together or with nano-CaCO3 capsulated by POE-g-MAH elastomer is large.

采用熔体流动速率较低的EPS30R与纯POE-g-MAH共混制备的增韧改性剂，在PBT基体中的分散相变得粗大且不均匀，共混物的脆韧转变推迟。SEM显示，纯POE-g-MAH增韧剂使PBT共混物发生脆韧转变时，弹性体分散相颗粒产生塑性变形，诱发基体屈服而吸收能量。

The most remarkable difference of serrate Castanopsis leaves to Castanea is that in Castanopsis the teeth are always irregularly spaced and confined to the one-half to two-thirds superior part of the lamina.

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例，溶骨型13例，混合型17例；X线对骨质破坏、骨膜反应、软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%；10例CT表现均可见骨质破坏、软组织肿块及瘤骨，CT对骨膜反应、筛孔征和Codman三角的检出率为90%、90%和11%；CT对显示细小肿瘤骨和筛孔征最敏感，但对Codman三角的显示不如X线平片；32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代，T1WI呈低～等信号，T2WI呈混杂信号，7例合并出血，24例中央坏死囊变，32例增强扫描均呈不均匀强化及瘤周可见水肿区。

The results illustrate that the collisional absorption have a maximum value when the collision frequency is near the radiation frequency.

当入射电磁波的频率很低时，不均匀磁化等离子体中碰撞对雷达波的吸收非常小。

Vanadium mainly exists as independent minerals or in clay minerals in the form of isomorphism, with a small amount absorbed by clay minerals and limonite. Nickel mainly exists as independent minerals. Molybdenum occurs as colloidal sulfides with carbon, sulfur and clay, and forms molybdenite through thermal metamorphism. Uranium is unevenly scattered in collophanite and carbonaceous_argillaceous materials in the form of isomorphism or adsorption. REE mainly occur in collophanite in the form of isomorphism. Copper, lead and zinc chiefly exist in sulfides or sulfo_arsenides and are concentrated in the metallic layer.

钒或以独立矿物存在，或以类质同象赋存在粘土矿物中；镍主要以独立矿物存在；钼主要与碳、硫、粘土一起呈钼硫化物胶状集合体，经热接触变质作用后形成辉钼矿；铀呈不均匀分散在胶磷矿和碳泥质中，呈类质同象或吸附状态存在；稀土元素主要呈类质同存在于胶磷矿中，部分呈吸附状态存在；铜、铅、锌主要以硫化物和硫砷化物等存在，多富集在金属层中。

First, with multi-centered concentralization and regular intersection of azonality and zonality, the villages are not uniformly distributed. Second, basically in agreement with the differences in rainfall, population distribution and regional economy, the number of cancer villages recedes from eastern part to western part in a graded pattern.

其地理分布有两个特点：一是空间分布不均匀，呈现多中心集中形态，体现出非地带性和地带性规律的交叉；二是癌症村数量由东向西递减呈梯度分布，与我国的水资源、人口分布和区域经济差异基本一致。

The sort and reason of grinding burn were analyzed. Based on the characteristic of the coned shape grinding wheel, the fac-tors of affecting the depth of the thermal damage layer were found.

锥面砂轮磨齿机工作时，由于工件受热和冷却、膨胀和收缩等不均匀性及磨削过程中各种变化因素的作用，极易产生磨削裂纹和烧伤。

Higher, mixed and cystal low density, inhomogeneous or circular enhancement were showed on CT.

CT扫描显示稍高密度区、混合密度区、囊性低密度区，不均匀增强或环形增强。

Results The splenic infraction was showed triangular or unr egular low density regions which had no enhancement,Metastasis tumor of spleen had imaged cystiform low density single or several masses,The patho logicai presented little nodular or circle enhancement.Primary lymphoma of spleen had presented part range low density regions and uneven enhancement .

结果 脾梗塞呈三角形或不规则形低密度区，病变无强化；脾转移瘤为囊状低密度肿块，单发或多发，病灶呈小结节状或环形强化；脾原发恶性淋巴瘤，呈局灶性低密度区和不均匀强化。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
