This research shall be obtain that ocean-sand motor shall have more compressive strength early, but later strength shall descend, by means of non-standard sand mixing sample is quite obvious. By means of 50% ocean-sand substitutes for river-sand to mix fine aggregate compressive strength early shall be risen 20%~30%; Adds slag to ocean-sand or a half of river-sand and ocean-sand to make motor test sample, Compressive strength、bending strength and tensile strength shall be according to slag additament, by means of. slag add itament substitutes for cement 40%~60% is most. But slag be able to substitute for cement is too enough, 1ater strength shall be descent.

由本研究可得知海砂拌和的水泥砂浆，其早期抗压强度较高，而晚期强度则有下降的趋势，其中以非标准砂拌和效果最为明显；若以50%海砂替代河砂做为拌和细骨材，其早期抗压强度约上升20%~30%；添加炉石於海砂或河砂、海砂各半的水泥砂浆，其抗压、抗弯及抗拉强度，会随著炉石添加量增加而增加，其中以40%~60%炉石替代量为最佳，但是炉石替代量过高，晚期强度会下降；在相同水灰比状况下以海砂拌和水泥砂浆做比较，以非标准砂拌和有较高的抗压强度，其强度约比标准砂高10%左右。

It is said that the first real violin was built by Andrea Amati in the first half of the 16th century by order of the Medici family, who had asked for an instrument that could be used by street-musicians, but with the quality of a lute, which was a very popular instrument among the noble in that time.

State them.""In the first place. you will give him half an hour's breathing spell midway of the road; he will eat; and some one must be by while he is eating to prevent the stable boy of the inn from stealing his oats; for I have noticed that in inns the oats are more often drunk by the stable men than eaten by the horses.""

Then the paper deduced the quench development characteristic of MgB2 tape by all the above study. The work environment cooled by GM cooler is an adiabatic environment. However the environment cooled by liquid helium is incomplete an adiabatic environment. In order to simulate the adiabatic environment, the tape was remodeled as follows. The tape is bundled by vitreous riband in half pile mode, and the angle of the tape and the riband is 45 degree. Then use cryogenic epoxy hardener to coat the surface of the riband.

Methods The SPF mice were treated with MED or optimized MED in dose of 29.3 g/kg and 18.6 g/kg per day respectively by intragastric administration for five days continuously. And then, the various dysmnesia mouse models were prepared respectively with Scopolamine (3 mg/kg), Cycloheximide (120 mg/kg) by intraperitoneal injection and 40% alcohol (0.1 mL/10 g body weight) by intrag astric administration on the sixth day. Next day, memory result was estimated by using Step-down Test and Dark-avoiding Test after the mice were administered for half or an hour.

About a Year and half after I had entertain'd these Notions, and by long musing, had as it were resolved them all into nothing, for want of an Occasion to put them in Execution, I was surpriz'd one Morning early, with seeing no less than five Canoes all on Shore together on my side the Island; and the People who belong'd to them all landed, and out of my sight: The Number of them broke all my Measures, for seeing so many, and knowing that they always came four or six, or sometimes more in a Boat, I could not tell what to think of it, Or how to take my Measures, to attack Twenty or Thirty Men single handed; so I lay still in my Castle, perplex'd and discomforted: However I put my self into all the same Postures for an Attack that I had formerly provided, and was just ready for Action, if any Thing had presented; having waited a good while, listening to hear if they made any Noise; at length being very impatient, I set my Guns at the Foot of my Ladder, and clamber'd up to the Top of the Hill, by my two Stages as usual; standing so however that my Head did not appear above the Hill, so that they could not perceive me by any Means; here I observ'd by the help of my Perspective Glass, that they were no less than Thirty in Number, that they had a Fire kindled, that they had had Meat dress'd.

我自从有了这些想法之后，平时就经常会想到这件事，可是因为没有机会付诸实施，因此一直都毫无结果。这样大约又过了一年半光景。一天清晨，我忽然发现有五只独木舟在岛这头靠了岸，船上的人都已上了岛，但却不知道他们去哪儿了。他们来的人这么多，把我的计划彻底打破了。因为我知道，一只独木舟一般载五、六个人，有时甚至更多。现在一下子来了这么多船，少说他有二三十人，我一个人单枪匹马，如何能对付他们呢！因此，我只好悄悄躲到城堡里去，坐立不安，一筹莫展。

The products were identified by IR,NMR,MS and elemental analysis. In our method,K.OH was used in place of NaOH to synthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate was purified on a silica gel column with chloroform/ethylacetate(4:l,v/v) as eluent and further purified by triturating with hexane/acetone(2:l,v/v).The luminescence produced by DMAE-NHS is a flash light with maximumemission at 0.4s and decay half-time of 0.9s. The luminescence intensity is 6.11x10 cps/mol,which is affected by the composition of trigger and surfactant.
