Shape setup （SSU） system is the core technology for hot strip mill （HSM）. A precise SSU system was used to improve the strip quality for HSM. The function of SSU, setup, and feedback was introduced. The main mathematical models of roll gap profile and longitudinal strain difference are set up. Strip profile allocation strategy was researched according to the SSU system of a domestic 1 700 mm HSM. The SSU system was put into practical use and the measurement results showed that strip flatness variation and strip profile variation could be controlled in target scope.

Dimensions of one kind of stainless steel plate before finish rolling were obtained through analysis of the rough rolling processes by finite element method and updated geometrical method. The FE models of finish rolling process with a front edge roll were built, and influences of the edge rolling reduction on the stress change in the plate edge during finish rolling were analyzed. The results show that when the edge rolling reduction is increased from 0 mm to 2 mm, the compressive stress in plate corner clearly increases in edge rolling process, and the zone of tensile stress during whole rolling decreases; when the edge rolling reduction is increased from 2 mm to 5 ram, the compressive stress in the plate corner seldom changes, and the compressive stress decreases after the horizontal rolling.

黑花生因富含花青素而深受消费者青睐。为了探索黑花生高产优质的适宜氮肥和钙肥用量,本研究以黑花生品种济花黑1号为研究对象,设置不同的施氮量和施钙量处理,分析比较不同处理下农艺性状、荚果成熟饱满度、产量和品质的差异。结果表明,施氮120~360 kg/hm^(2)和施钙300~600 kg/hm^(2),花生荚果产量分别较不施氮和不施钙对照增产5.95%~15.56%和5.40%~10.39%,N240和Ca450处理产量最高。氮和钙促进了花生营养生长,提高了单株结果数、单株饱果数、饱果率、百果质量、百仁质量和出米率。N120和N240处理的荚果产量和成熟饱满度差异较小,且均显著高于对照;Ca450处理的荚果产量和成熟饱满度显著高于对照,在钙处理中表现最优;最优用量之后继续增施氮肥和钙肥不利于荚果发育和产量形成。施氮和施钙提高了花生籽仁蛋白质、脂肪、总氨基酸、精氨酸等营养物质含量,增加了油酸含量和O/L比值,降低了饱和脂肪酸(硬脂酸和棕榈酸)含量,提高了黑花生的营养品质和保健价值。施氮120 kg/hm^(2)和施钙450 kg/hm^(2)是黑花生高产优质高效栽培的优选施肥方案。研究结果为黑花生氮肥和钙肥合理应用提供了依据。

BACKGROUND: Transforming growth factors (TGF)-beta 1, TGF-beta R2 and Smad4 belong to the TGF family, and play important roles in carcinogenesis and the development of carcinoma, especially hepatocellular carcinoma (HCC). TGF-beta 1 is a multipotent polypeptide, which inhibits the growth of epithelial cells including hepatoma cell lines and hepatocytes by inducing apoptosis. TGF-beta R2 forms a heterodimeric complex upon binding to TGF-beta, and then generates the first step in the signal transduction pathway leading to growth inhibition in coordination with the type I receptor. Smad4 protein is an important mediator in the TGF-beta signaling pathway, and negatively regulates the growth of epithelial cells. This study aimed to detect the expression of TGF-beta 1, TGF-beta R2 and Smad4 in HCCs and their adjacent normal tissues, while assessing its relations with the clinicopathological parameters of HCC. METHODS: Forty-seven HCC specimens and their adjacent normal tissues were obtained surgically at the Affiliated Hospital of Medical College, Qingdao University. The expression of TGF-beta 1, TGF-beta R2 and Smad4 was separately detected by immunohistochemistry in all HCC specimens and their adjacent normal tissues, and its relations with the clinicopathological parameters of HCC were assessed. RESULTS: The positive expression of TGF-beta 1 was 72.34% in the HCC specimens, which was higher than that in the adjacent normal tissues (P < 0.001). The positive expression of Smad4 and TGF-beta R2 was 34.04% and 59.57% respectively in the carcinoma specimens. The expression of TGF-beta 1, TGF-beta R2 and Smad4 was significantly higher in groups with a tumor embolus of the portal vein, integrity of the amicula, and Edmondson's III-IV than that in other groups, but it was not related to tumor size (P < 0.05). CONCLUSIONS: TGF-beta 1 may play an important role in the occurrence and development of HCC. Combined detection of TGF-beta 1, TGF-beta R2 and Smad4 may be useful for the

Dissolved organic carbon(DOC) is an important component of the terrestrial carbon ***,the sources and controlling factors of DOC in soils remain *** this study,the effects of nitrogen(N) amendment and crop growth on DOC in soil solution were examined at a maize-wheat rotated field located in the central Sichuan Basin in southwestern *** treatments in this study included 150 kg N ha-1 season-1,200 kg N ha-1 season-1 and the control without any fertilizer *** the whole experimental period,we observed significant decreases(pchange in DOC at the plots with crop *** estimated average contributions of plantderived DOC were 16%,24% and 32% of total DOC in the summer maize season and 21%,32% and 38% in the winter wheat season along with the gradient of N fertilizer application *** results implied thatthe crop growth could play a key role in the soil DOC production,and the N input enhanced DOC production by increasing crop *** relationship between the DOC concentrations and the crop root biomass was statistically significant for both the maize and winter wheat *** observations indicated that crop growth exerted greater influence on the seasonal variability of DOC concentration in soil solutions at the experimental site,which overwhelmed the effect of soil native organic matter decomposition on DOC concentrations in soil solutions.

研究了兼有电光效应和磁光效应的晶体内电光与磁光效应的互补特性及其传感应用.在光强度调制条件下,晶体中偏振光波的电光调制与磁光调制具有互相补偿的效果,从而能够使输出光强度保持为一个固定值.基于这种互补特性,提出了一种利用单块闪烁锗酸铋(Bi4Ge3O12,BGO)晶体的电光补偿型光学电流(磁场)传感器,其光学传感单元由两个偏振器和一块平行四边形BGO晶体组成.该晶体自身能够产生π/2的光学相位偏置,同时兼用作电流传感和电光补偿元件,通过控制BGO晶体的外加电压,能够实时补偿被测电流(磁场)变化引起的磁光旋转角和输出光强度的变化,从而实现电流(磁场)的闭环光学测量.实验测量了5.0 A范围内的工频交流电流,所需要的电光补偿电压约为21.2 V/A,补偿电压与被测电流之间具有良好的线性关系,其非线性误差低于1.7%.

利用折射率椭球分析法,分析了某些具有多重光学效应的光学晶体在两个外场同时作用下的一些特有调制规律.结果表明,当晶体的折射率椭球方程的三个交叉项中只有一项x1x2不为零时,可以得到其外场诱导新主轴折射率及其主轴取向的简单计算式.据此可以揭示出某些晶体在两个外加电场同时作用下将具有双横向电光Pockels效应,例如ˉ6点群的电光晶体.但一般晶体在双横向应力作用下不具有与双横向电光效应类似的调制特性,其弹光双折射大小与其应力差成正比,其双折射主轴方向一般为固定值.在相互垂直的外加应力和电场同时作用下,某些晶体(例如ˉ43m点群晶体)的双折射大小与外加应力和外加电场的加权几何平均值成正比,且新折射率主轴旋转角由外加应力和外加电场的比值来确定.晶体的上述双参量调制特性对设计新型光学调制器或传感器具有重要指导意义.
