Moreover, supersensitization as well as its mechanism by stabilizers is studied in spectral-sensitized AgCl emulsion Results indicate that the adding order of stabilizer and sensitizing dye has great influence on the sensitivity of emulsion and only stabilizer added after sensitizing dye can supersensitization be obtained Apart from supersensitization and fog-inhibition by stabilizers, it is also significant to spread the amount of addition of dye, which can lead the further improvement of sensitivity of emulsion.

本文还研究了稳定剂在氯化银乳剂中的超增感作用并应用多种手段研究了其超增感作用机理。结果说明，稳定剂与增感染料的添加次序对乳剂感光度有非常重要的影响，只有在增感染料之后加才可能产生增感作用。在一定的稳定剂添加范围内，它不仅可以提高氯化银乳剂的感光度、降低灰雾，而且还能加大增感染料的用量，进一步提高乳剂的感光度。这对乳剂的光谱增感来说具有重要意义。

Exhibiting angle unconformities or erosion unconformities in different part of the basin, these surfaces are obvious to be recognized on seismic profiles.T1 conformity, separating Eogene from Neogene, was formed during the whole basin uplifting and erosion by the end of Eogene.T1 unconformity denuded unbearing strata differently, and the deeper and thickest erosion lies on the southern margin of the basin, which reflects the activity of southern Jiangnan paleo-terrene. In conclusion, the major erosion belts extending along NW direction reflects NE-SW compression and slipping caused the Eogene basin uplift and strengthen the earlier NW direction extending low convex, and formed the NW direction extending depress and erosion belts.

古近系和新近系之间的T1不整合面形成于古近纪末期的盆地整体抬升，对下伏地层造成不同程度的剥蚀，沿盆地南缘的剥蚀层位深，剥蚀量大，反映盆地南缘整体相对隆起，与江南古陆的隆起作用有关。T1界面剥蚀带走向以北西向为主，反映了盆地在古近纪末受到了北东－南西向的挤压或压扭作用，该作用造成盆地整体抬升，强化了北西向展布的低凸起，产生了近北西向的洼陷和剥蚀带。

试验研究表明，掺加适量的减水剂、纤维素和引气剂均能从不同方面对砂浆性能起到一定的改善作用，但单独使用时作用有限，甚至会产生负作用。

The expression of HSP70 and HSP70mRNA and the activity of SOD and NOS in uterus were elevated with preventive acupuncture and preventive moxibustion and the influence on the activity of SOD and NOS was mainly refected in 12th and 16th month. It indicated that preventive acupuncture and preventive moxibustion on Guanyuan point could relieve the abnormal activity of center of stress, promote the expression of HSP70 and HSP70mRNA and the activity of SOD and NOS in uterus so as to maintain the normal structure and function and prolong the retrograde degeneration of uterus. It might be one of mechanisms of protecting uterus with preventive acupuncture and preventive moxibustion.

提示逆针灸关元穴对随后更年期大鼠子宫产生保护作用机制可能通过减缓应激中枢的异常活跃状态，提高不同月龄外周子宫组织细胞HSP70及mRNA的表达，以促进组织SOD、NOS活性的增强，对抗应激激素及卵巢功能衰退引起的子宫靶器官的结构及功能的改变，提高机体抗氧化能力，增强NO/NOS的局部调节作用，减轻随后更年期衰老过程中自由基对组织器官的损害及组织器官功能紊乱，对于维持子宫正常的结构和功能，延缓子宫退行性变具有重要作用。

Then it emphasizes that anchor rope support can improve the reinforcing effect of wall rock and the "anchor rope--anchor bar" combined support is effective.

分析了锚索支护在近距离煤层巷道中的支护作用，并对其作用机理和产生的效果进行了理论分析，强调锚索支护具有提高围岩的补强作用&，锚索—锚杆&联合支护行之有效。

Vacuum consolidation test and load consolidation test were performed and compared for different kind of soil samples. After analyzing the results of tests, the four major mechanisms of vacuum consolidation were defined as: variation of capillary potential, drainage of sealed bubbles, vaporization and action of atmosphere pressure, in which, the action of atmosphere pressure is the most important factor.

首先对不同土样进行了一系列室内真空固结和加载固结的对比试验，通过对试验结果的比较分析，明确了抽真空引起土样固结的原因，即抽真空作用会在四个方面对试样产生影响：毛细管势的改变、封闭气泡的排出、汽化现象及大气压的作用，而其中大气压的作用是最主要的。

The results show that space finite analysis results are close to test ones, bottom chords suffer axial force and large in-plane bending, and the max stress is nearby each middle internode. The max stress of node crossbeams occurs in No.2 bottom flange, and that of internode crossbeams happens in ones lying in the middle of every internode. The concrete slab is in tension at the longitudinal direction, and also suffers bent at vertical loads. The degree of completely-composite model taking part in the combined actions is about 55%, while that of semi-composite model is 42%-43%. The combination of concrete slab and bottom chord increases the degree of floor system taking part in the combined actions, lightens the burden of bottom chord, and reduces out-of-plane bending of node crossbeams especially the ones near bridgehead. Stress and displacement of main truss can be evaluated by a equivalent plane rigid frame in preliminary design, and effective stiffness of bottom chords are composed of original ones and concrete slab, and the concentrated load from deck can be translated into uniform load.

研究结果表明：空间有限元分析结果与试验结果较吻合；下弦杆受到轴向拉力和较大的面内弯矩作用，各节间最大应力出现在节间中点附近；节点横梁最大应力发生在横梁2的下翼缘，节间横梁最大应力发生在位于端节间中部的小横梁上；混凝土板顺桥向整体受拉，并在竖向集中荷载作用下产生弯曲变形；全结合模型大部分节间内的桥面板参与主桁共同作用的程度为55%左右，半结合模型桥面板的参与程度为42%~43%；桥面板与下弦杆结合能够增加桥面板的参与程度，减轻下弦杆荷载，减少节点横梁尤其是靠近桥头横梁的面外弯曲；对桥梁进行初步设计时，主桁杆件的位移与内力可按照1个等效的平面刚架计算，下弦杆的等效刚度由原下弦杆截面和混凝土桥面板截面组合而成，桥面荷载可转化为均布荷载施加。

The plastic go down the hopper smoothly and is gripped by the thread of the screw. It is forced to go toward the direction of the gear end along with the rotation of the screw. A mechanical transferring process is formed. During the running of the plastic from the feed port to gear end, a high pressure is formed in the process of plastic curing due to the gradual decreasing of the thread depth and the resistance of filter gauze, splitter plate and gear end. The high pressure helps to press the raw material and improve its heat conductivity performance and the quick melting of the plastic, at the same time, the gradual increasing pressure can help the gas which is among material particles exhausted from the air holes.

在压力升高的同时，塑料一方面被外部加热，另一方面塑料本身在压缩、剪切、搅拌的运动过程中，由于内磨擦力也产生了大量的热，在外力和内力的联合作用下，塑料温度逐渐增高，其物理状态也经历了玻璃态--高弹态--粘流态的变化，一般地说来，在加料段中主要是玻璃态，在螺杆螺纹逐渐减少的中间部分压缩段中，物料主要处于高弹状态，同时也逐渐的熔融，而物料到压缩段后部和化段作用处于粘流态了，这时我们称塑料已完全塑化了，由螺杆推力作用将塑化的塑料定压定量的从机头中挤出。
