查询词典 operation of symmetric difference

A method using a tiny thermistor as heat transfer model was developed to measure thermophysical properties (thermal conductivity and thermal diffusivity) of three standand samples(ethanol, ethylene alcohol, solution of calcium chloride). Results showed that there was no significant difference between measurement and recommendation; results of thermal conductivity from thermistor method and heat probe method for carrot and potato samples showed no significant difference; results of thermal diffusivity between thermistor method and calculation for carrot and potato samples showed no significant difference.

灌注参数图像能直观显示肝脏良、恶性占位性病变血流动力学的不同特点；无论在何种背景下，恶性病变灶周组织与远端肝组织各同种参数间有显著差异，而良性病变灶周组织与远端肝组织各同种参数间无显著差异，以上特点可以鉴别肝脏占位性病变的良、恶性；肝硬化背景下，恶性病变的发生率明显增高；正常肝组织背景下，良、恶性占位病变组织灌注参数间无显著差异，鉴别诊断意义不大。

Result shows that the Apriona germari adult insect prefer to eat Broussonetia papyrfera and reject to eat other tree species which result in difference in natural life and fecundity. Total sugar and dissolvable protein content in the bark is not the cause of rejection. Difference of dissolvable sugar and amino acid may be the reason of preference while difference of dissolvable phenolics and tannin content may explain the rejection.

取食构树的桑天牛成虫取食量大，存活时间长，产卵量大，遗卵量少，其他3个树种则相反。4树种树皮内总糖和可溶性蛋白含量与桑天牛抗性无关，树皮内可溶性糖含量、总氨基酸和必需氨基酸含量对抗性有一定影响。4树种树皮内水溶性总酚含量和单宁含量差异对成虫取食有较大影响，酚类和单宁等次生物质对桑天牛成虫的忌避作用是导致抗性的主要原因。

Results l.Serum concentrations of VCAM-1 in PIH (93.39 + 57.3)ug/ml were higher than that in normal pregnant group. Serum concentrations of VCAM-1 in moderate(97.89 + 34.07)ug/ml and severe PIH(132.24 + 60.97)ug/ml were significantly higher than that in normal group.(P.05, P.01). There was no difference between serum levels of VCAM-1 mild PIH and normal pregnant group. 2.Serum levels of IL-6 in PIH group(102.17 ?48. 31)pg/ml were significantly higher than that in normal group(49.16 + 12.9)pg/ml.Serum levels of IL-6 in moderate(95.79+31.19)pg/ml and severe PIH( 127.27+11.3 8)pg,ml were significantly higher than that in normal group. There was no difference between serum levels of PIH in mild PIH (52.13 + 12.90)pg/ml and normal pregnant group. 3. In PIH group, serum concentrations of VCAM-1 correlate with the levels of IL-6,r=0.63. 4.The expression of VCAM-1 in cytotrophoblast of spiral arteries in normal pregnant group(100%) were significantly higher than that in PIH group.Theexpression of VCAM-1 in moderate PIH(37.50%) and sever PIH were lower than that in normal group.There was no difference between the mild PIH and normal group.Conclusions The increased levels of serum of VCAM-1 may participate in the process of vascular endothelium damages in PIH.
