I now began to consider, that I might yet get a great many Things out of the Ship, which would be useful to me, and particularly some of the Rigging, and Sails, and such other Things as might come to Land, and I resolv'd to make another Voyage on Board the Vessel, if possible; and as I knew that the first Storm that blew must necessarily break her all in Pieces, I resolv'd to set all other Things apart, 'till I got every Thing out of the Ship that I could get; then I call'd a Council, that is to say, in my Thoughts, whether I should take back the Raft, but this appear'd impracticable; so I resolv'd to go as before, when the Tide was down, and I did so, only that I stripp'd before I went from my Hut, having nothing on but a Chequer'd Shirt, and a Pair of Linnen Drawers, and a Pair of Pumps* on my Feet.

这时我想到，船上还有许多有用的东西，尤其是那些绳索，帆布以及许多其他东西都可以搬上岸来。我决定只要可能，就再上船去一次。我知道，要是再刮大风暴，船就会彻底毁了。因此，我决定别的事以后再说，先把船上能搬下来的东西通通搬下来。这么一想，我就琢磨再次上船的办法。看来，再把大木排撑回去是不可能了。所以，我只好等潮水退后，像上次那样泅水过去。决心一下，我就立即付诸实施。不过，在我走出木屋之前，先脱掉衣服，只穿一件衬衫、一条短裤和一双薄底鞋。

This paper stressed on the fact that electric displacement vector is a supplementary physical element,focused on a difference between D and D surface integral and on the condition of D=ε_0E_0 existence,and made a comprehensive and correct understanding for beginner.

着重说明了电位移矢量D是一个辅助物理量，强调指出D与D的面积分的意义不同，以及D=ε0E0成立的条件，从而使初学者对D建立起一个全面和正确的认识。

Not every subgroup of a D-group is also a D-group. If a subgroup is a D-group we call the subgroup "sub- D -group." The "commutator ideal" of G is the smallest sub-D-group containing its commutator subgroup. We found that the commutator ideal can be viewed as a finitely generated module over a ring when G is a finitely generated metabelian D-group.

并非每个子群都是一个可除群，若一个子群是可除群，我们称之为子可除群(sub-D-group)，而G 的交换子理想则是在G中包含其导出群的最小子可除群，我们发现当G是一个有限生成亚交换可除群时，其交换子理想是一个有限生成模。

As a whole,the notable characteristic of primary productivity in size-fractioned structure was that nanoplankton occupied comparatively significant advantage in Beibu Gulf.Nanoplankton has the largest contribution to gross primary productivity,and picoplankton was the secondary contributor,while microplankton the least.The contribution of microplankton for primary productivity in the north Gulf was more than that in the other waters.Nanoplankton and picoplankton contribute more to the gross primary productivity in offshore deep waters than in inshore shallow waters3.The Beibu Gulf can be divided into three ecoregions:Region-Ⅰis the ecoregion in inshore shallow waters of the north Gulf.In average,the water depth is 18m,DIN is 1.88μmol/L,DIP is 0.20μmol/L,N:P is 9.4:1,dissolved silicate is 5.17μmol/L,the Chl a conentration in surface layer is 2.27mg·m~(-3),the assimilation index in surface layer is 3.80mg/,the primary productivity is 198.78mgC/(m~2·d), and potential fishery production is estimated to be 0.24gC/(m~2·a) according to the primary productivity.The ecoregion is mainly affected by the northern coastal water systems,and may be fit for aquaculture;Region-Ⅱis the ecoregion in offshore deep waters of the north Gulf and the coastal shallow waters to the west Hainan Island.In average,the water depth is 35m,DIN is 2.01μmol/L,DIP is 0.18μmol/L,N:P is 11.2:1,disovled silicate is 4.23μmol/L,the chlorophyll a of surface layer concentration is 1.45mg·m~(-3),the assimilation index of surface layer is 4.12 mg/,the primary productivity is 276.60mgC/(m~2·d),and the estimated potential fishery production is 0.34gC/(m~2·a) according to the primary productivity. The ecoregion was mainly influenced by ocean current from the South China Sea, rivers in the west coast of Hainan Island and the water from Qiongzhou Strait.It may be fit for aquaculture and fishery;Region-Ⅲis the ecoregion in offshore deep waters of the mid and south Gulf.In average,the water depth is 75m,DIN is 0.77μmol/L, DIP is 0.15μmol/L,N:P is 5.1:1,disovled silicate is 3.05μmol/L,the chlorophyll a of surface layer concentration is 0.70mg·m~(-3),the assimilation index of surface layer averaged is 3.69mg/,the primary productivity is 350.89mgC/(m~2·d),and the estimated potential fishery production is 0.43gC/(m~2·a) according to the primary productivity.The ecoregion was mainly affected by the circulation inside Beibu Gulf, and may be fit for fishery.

After amputation, the expression of desmin appears first in the distal end epidermis and the peritoneum 4 d PA. The expression in the peritoneum lasts to the 14 d PA when expression of desmin appears in the musculature, while that in the distal end epidermis only lasts to the 8 d PA when the connective tissue below begins to express desmin. Moreover, from the 4 d PA, musculature and epidermis of the tube foot begin to express desmin and the expressions last to the 20 d PA. From 8-14 d PA, musculature of the ambulacral plate expresses myogenin and the peritoneum also expresses myogenin from 14-20 d PA. All these results indicate that precursor cells for muscle regeneration in adult starfish A.rollestoni are mainly from the distal end epidermis and the parietal peritoneum.

创伤后第4 d，顶端表皮层及体腔上皮中首先出现了desmin表达，体腔上皮中desmin的表达一直持续到第14 d，此时其上方的肌肉组织中也出现了desmin表达；而顶端表皮层中desmin的表达仅持续到第8 d，同时其下方的结缔组织也开始表达desmin；此外，从第4 d起，管足肌肉及管足表皮层开始表达myogenin，且该表达一直持续到创伤后的第20 d；而第8 d起，步带板肌肉也出现了myogenin的表达，此表达一直持续到第14 d；从第14 d起，体腔上皮也出现myogenin表达，且一直持续到第20 d。

June 28. Having been somewhat refresh'd with the Sleep I had had, and the Fit being entirely off, I got up; and tho' the Fright and Terror of my Dream was very great, yet I consider'd, that the Fit of the Ague wou'd return again the next Day, and now was my Time to get something to refresh and support my self when I should be ill; and the first Thing I did, I fill'd a large square Case Bottle with Water, and set it upon my Table, in Reach of my Bed; and to take off the chill or aguish Disposition of the Water, I put about a Quarter of a Pint of Rum into it, and mix'd them together; then I got me a Piece of the Goat's Flesh, and broil'd it on the Coals, but could eat very little; I walk'd about, but was very weak, and withal very sad and heavy-hearted in the Sense of my miserable Condition; dreading the Return of my Distemper the next Day; at Night I made my Supper of three of the Turtle's Eggs, which I roasted in the Ashes, and eat, as we call it, in the Shell; and this was the first Bit of Meat I had ever ask'd God's Blessing to, even as I cou'd remember, in my whole Life.

这些我在故事一开始就提到了。父亲说，我如果执意采取这种愚蠢的行动，那么，上帝一定不会保佑我。当我将来呼援无门时，我会后悔自己没有听从他的忠告。这时，我大声说，现在，父亲的话果然应验了：上帝已经惩罚了我，谁也不能来救我，谁也不能来听我的呼救了。我拒绝了上天的好意，上天原本对我十分慈悲，把我安排在一个优裕的生活环境中，让我幸福舒适地过日子。可是，我自己却身在福中不知福，又不听父母的话来认识这种福份。我使父母为我的愚蠢行为而痛心，而现在，我自己也为我的愚蠢行为所带来的后果而痛心。本来，父母可以帮助我成家立业，过上舒适的生活；然而，我却拒绝了他们的帮助。现在，我不得不在艰难困苦中挣扎，困难之大，连大自然本身都难以忍受。而且，我孤独无援，没有人安慰我，也没有人照应我，也没有人忠告我。想到这里，我又大喊大叫：&上帝啊，救救我吧！我已走投无路了啊！&多少年来，我第一次发出了祈祷，如果这也可算是祈祷的话。现在，让我重新回到日记上来吧。

The French and Italian poets gave preference to the Italian form of sonnet—two groups of four lines, or quatrains (always rhymed a-b-b-a a-b-b-a) followed by two groups of three lines, or tercets (variously rhymed c-c-d e-e-d or c-c-d e-d-e)—which created a sonorous music in the vowel rich Romance languages, but in Shakespeare it is artificial and monotonous for the English language.

法国和意在利诗人优先使用意大利格式的商籁诗----两组四行诗（总是按a-b-b-a a-b-b-a的格式押韵）加上两组三行诗（按c-c-d e-e-d或 c-c-d e-d-e格式押韵），这就在元音丰富的罗马语言中产生了一种感人的音乐节奏，然而放在莎士比亚的英语作品里，就变得矫揉造作和枯燥单调。
