Results show that amplitude of displacement excited by vertical incidence wave is larger than that excited by inclined incidence wave and not influenced greatly by the incidence angle. In vertical incidence, amplitudes of displacement of two points at the same altitude along each cavern are basically identical and maximum relative displacement occurs between top and bottom point of the cavern. While in the case of inclined incidence, displacement amplitude on sides meeting the wave is larger than that on leed sides, and maximum relative displacement occurs on left skewback and bottom of the cavern.
结果表明,位移幅值受入射角度的影响不敏感,竖直入射比斜入射情况要大;竖直入射时,各洞室两侧同一高程处的位移幅值基本相同,相对位移差最大部位为洞顶与洞底,而斜入射时迎波面比背波面一侧位移大,且相对位移差最大部位为洞室迎波面的左拱座与洞底。

Main job is to guarantee the scraping interaction and equipment on both sides of the friction surface or can obtain higher precision and accuracy, precision and shape accuracy, precision and contact transmission because of good lubrication, manual and repeatedly is worthy, large amounts of wind, time-consuming, scraping the time needed for different devices vary, such as boring slider and slide block wind profiling, between the match before measuring clearance between the original value, and then according to the technical requirement to measure the value of time and scraping scraping, then apply DanFen red on the slider, manual let slip on the slide seat back and forth, they do straight-line movement between full contact and friction, reoccupy scraper scraping friction creates the contact point, so repeatedly, until the technical requirements for the match, single within 2 days, must blow to the boring if all the time to work with wind, a half month is required.
刮削过程。刮削工作主要是为了保证设备相互接触并摩擦的两面间能获得较高的尺寸精度、形状精度、位置精度、接触精度、传动精度和良好的润滑,因是手工操作且需反复配刮,故工作量大,耗时较长,设备不同,刮削所需时间也各不相同,例如镗床上滑座与下滑座间的配刮,刮削前先测量出二者之间原有的间隙值,然后根据工艺要求测算出需刮削值及每次的刮削量,再将红丹粉涂于上滑座之上,手工让上滑座在下滑座上来回做直线运动,使它们之间充分接触和摩擦,再用刮刀刮削摩擦产生出的接触点,如此反复多次,直至技术要求范围之内,单此项配刮需2天左右,若对于整个镗床所有配刮工作的时间总和,则需半个月左右。

After pretreatment with TFP, although the conductance of cultivate solution of strawberry seedling under NaCl stress was not increased, growth was inhibited obviously by TFP, while the leaf relative electric conductivity in strawberry increased, leaf holding ability was reduced. The inhibiting response increased with the concentration of TFP increasing. On the contrary, conductance in cultivate solution was increased by Ca(NC?3)2 treatment, but the leaf relative electric condu
用Ca(NO_3)_2和TFP培养处理NaCl胁迫的草莓幼苗,发现TFP培养处理虽然不增加培养液的电导值,但明显抑制盐胁迫草莓幼苗的生长,增加了叶片膜透性,降低了叶片保水力,抑制作用随TFP浓度的增加而增大;而Ca(NO_3)_2处理虽然增加了培养液的电导值,但降低了幼苗叶片膜透性,提高了叶片保水力,因而减轻了NaCl
