Using the relations between Hermite and Laguerre-Gaussian modes and expanding the window function of two-dimensional rectangular hard-edged apertures into a finite sum of complex Gaussian functions, the propagation of complex- argument Laguerre-Gaussian beams through a paraxial optical ABCD system with a rectangular hard-edged aperture is studied. An analytical propagation equation is derived and used to study the diffraction at the rectangular hard-edged aperture and the focusing properties of complex-argument LG beams.

This paper examines the soil characteristic and liquefaction degree of hard shell seams at the subaqueous delta of the Yellow River. Four typical areas were chosen for measuring, testing and studying. The hard shell seam strength was measured by in-situ Proctor penetrometer. Undisturbed soil sample of 1 m long was excavated for laboratory soil property test. Sledge hammers were dropped down freely to hit the load board to simulate the wave force acted on the hard shell seam. The excess pore pressure and strength variation were observed. The liquefaction depth of the hard shell seams at four study areas under different wave storms were calculated by theory.

为揭示黄河口水下三角洲硬壳层的土性特征和风浪作用下的液化破坏状况，选择典型研究区，在现场利用普氏贯入仪测试硬壳层的强度特征，原位取1m原状样进行室内土工试验；利用重锤锤击荷载板的方式模拟波浪对硬壳层的动力作用，通过孔压探头和普氏贯入仪实时监测土体内孔压和振动前后强度的变化；通过理论计算研究硬壳层在不同风浪等级下的液化深度。

Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.

That aspectant male student hostels, at the same time of last year, once full of smoke of gunpowder; the clothesline that outside the window, wafting a white shirt that fell from an unknown hostel; I can't remember in what time, the lawn with a standing love flower brand had been full of paths because of the buddies always looked for the shortcuts; female student hostels, almost became the eonian forbidden zone for boys; whether the doors of study rooms in multifunction building are still open, we used to working very hard in that room for a few weeks during the preparation of Graduate Examination, I think there is no body there nowadays, I am always grateful for the days of immersing ourselves in hard study; no matter what, I gained a lot from that……Scenes like the pieces of gorgeous barbolas, thread in a movie that about to curtain call, playing our happiness and sadness, recording our youth and past, also witnessing our friendship and torch of Hymen!

再看一看吧……那赫然相对的男生楼，就在去年的这个时候，还曾经硝烟四起；窗外的晾衣绳，飘荡着不知哪个宿舍落下来的白衬衫；插着爱护花草牌子的草坪，记不清什么时候已经被抄近路打水的兄弟们踩出了一条小路；路旁的女生楼，对男生来说，几乎成为永远的禁区；综合楼自习室的门还开着么，考研时鏖战过几个月的那个屋子，如今应该没有什么人了吧，一直对那段埋头苦读的日子心存感激，不论结果如何，它让我收获了很多……一幕幕的场景就像一张张绚烂的剪贴画，串连成一部即将谢幕的电影，播放着我们的快乐和忧伤，记录着我们的青春和过往，也见证着我们的友谊和爱情！

One, study character is in us in education, discover not hard, the student's study, dependence is very strong, always be used to a teacher all-around specific arrangement, once give them time, a lot of students appear not know what to do, faineant even; is studying a method, be used to machinery repeating, face the study rhythm during study and capacity, times feeling gets tired of the study mood; that dealt with; him student to affect them with the expectation fixed position of parent impropriety many students and parent often the study result with the static state, regard only hope as orientaton, not to be pooh-poohed makes dynamic analysis at whole to learning process, undertake ego is adjusted scientificly....

一、学习品质在我们在教学中，不难发现，学生的学习，依靠性很强，总习惯于教师全方位具体布置，一旦把时间交给他们，很多学生就显得无所适从，甚至无所事事；在学习方法上，习惯于机械重复，面对学习期间的学习节奏和容量，倍感疲于应付；学生本人和家长不适当的期望定位影响了他们的学习情绪；不少学生和家长往往以静态的学习成绩，作为唯一的期望取向，不善于对学习全过程作出动态分析，科学地进行自我调适……。

The biomechanical tests showed that two kinds of artificial bones had not significant difference on compressive strength and Young\'s modulus(P＞0.05),while the flexural strength of nano-nacre artificial bone was less than the control group(P＜0.05).3.The results of CCK-8 showed that the difference were not significant in each group,the proliferation of osteoblast reached the peak at the 5th day;7 days after being co-cultured,the total protein content of study group was higher than control group and blank group(P＜0.05),while the difference between control group and blank group was not significantP＞0.05The difference of alkaline phosphatase activities among three groups was not significant(P＞0.05The SEM view showed that osteoblast attached and grew well in two kinds of artificial bone.4.X-ray photography showed that two kinds of powder started to degrade in 2 weeks;this phenomenon became more appear in 4 weeks,nano-nacre powder degraded faster than micron-nacre powder,while the hole shadow was easy to be found;in 8 weeks,all the femoral holes recovered and returned to normal bone mineral density in all groups.Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone grew fastest around the bone defect area in study group,while most slowly in blank groupP＜0.05 SEM(scanning electron microscope observation showed that nano-nacre powder degraded more quickly.The same result can be found through the demineralized sections morphometric analysis,and both of the composite artificial bones made from those two kinds of nacre powder had the good connection with the adjacent tissue in rats body without apparent inflammatory response.5.X-ray photography showed that rabbit\'s bone defects healed faster in study group since NNAB implanted than in control group since MNAB implanted.At 24 weeks after operation,bone density in radial defects had nearly accessed to the normal area,while lower in control group,and turned up nonunion in blank group;The checking of BMD showed that results in study group were higher than those in control group at 8,16 and 24 week(P＜0.05), and the difference between the BMD values in study group at 24 week and those in blank group was not significant(P＞0.05).The gross specimens showed satisfactory histocompatibility both in study group and in control group,with bone tissue growing from two sides into the center of implanted materials; Normal slices in HE stain and hard tissue grinding slices in Stevenel\'s blue/Van Geison\'s picro-fuchsin stain showed that the bone growth tendency was better in study group than that in control group,and the medullary cavity had been penetrated to the implanted materials in study group at 24 week;Analysis of tetracycline fluorescent double marks in the hard tissue grinding slices indicated that new bone in both groups grew fastest 8 weeks after surgery,while slow down at 16 week.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
