Pistillata. However, the mean growth rates of S. pistillata in two mesocosms at 25℃ were significantly different. The mean growth rates of S. hystrix in two mesocosms at 28℃ were significantly different and did not show a consistant relationship compared to those of S. pistillata.

In this paper, the 3-D finite element relocating mesh method is used to calculate the temperature field and the thermal creep stress field of spillway dam and mid level outlet dam in certain roller compacted concrete gravity dam, sensitivity analysis have been down with different parameters, such as placing temperature, the location of cooling pipe, cooling temperature, time for water supply, ascended-layer of concrete, intermissive time and different placing time, and the commendatory construction scheme have been put forward in such analysis; according by the test result on the two scheme of concrete aggregate combination (basalt as coarse aggregate and limestone as fine aggregate, basalt as coarse aggregate and basalt as fine aggregate), simulation analysis on temperature field and thermal creep stress field of the commendatory construction scheme have been down, and analysis have also been down on temperature field and thermal stress field of the two different aggregate combination, the result indicates that the spillway dam and mid level outlet dam which adopted these two aggregate combination can both satisfy the require of design crack resistance in concrete, furthermore limestone as fine is better than basalt as fine aggregate; the effect of summer water storage and winter water storage on the temperature field and thermal stress field have been analyzed, comparing with winter water storage, in summer water storage scheme the maximum tensile stress at abnormal concrete in upstream fill is decreased by 0.1～0.3MPa and there are no evidence change of the maximum tensile stress at other parts, which indicate that summer water storage is avail for the crack resistance of upstream fill; according to the simulation calculating result and comparing temperature simulation calculating results and temperature controlling measures of some similarity projects both completed and construction, synthesis appraise have been carried to the design temperature controlling measures of dam, and the temperature controlling measures of this project have been brought forward, all these have great reference value on the design of temperature controlling measures and the optimization of the construction scheme.

Seven grapevine cultivars originated from different regions, i. e.'Carbernet Sauvignon' and'Queen of Vineyard'(two members of the Western Europe Cultivars Group),'Rizamat'(a member of the East Cultivars Group),'Red Double Taste'(a hybridized cultivar from Vitis vinifera L. and V. labrusca L.),'1103Paulsen','Red Globe'and 'Autumn Royal'(two new hybridized cultivars between cultivars groups which were warmly planted in recent years) were selected. After different drought stress, a combined measurement of gas exchange and chlorophyll fluorescence was conducted to evaluate the effects of drought stress to photoinhibition, as well as the role of photorespiration and xanthophyll cycle in photoprotective mechanism. After photorespiration and xanthophyll cycle were separately inhibited, the complementary effect of these two photoprotective pathways was discussed. Detached leaves of different grapevine cultivars, i. e.'Cabernet Sauvignon','Cabernet Franc','Merlot', and a rootstock,'1103Paulsen'were selected as materials, and photoinhibition degree, photorespiration activity as well as its photoprotective function under drought stress were studied. The results are as follows: 1. Under the same drought stress treatment, different photoinhibition degrees formed in different grapevine cultivars.

This contributes to the rigidity of the bearing and a precise radial guidance of the shaft. For special applications, full-complement cylindrical roller bearings are employed. The cylindrical roller bearing designs are shown in Figures 1.20 and 1.21.The designs of cylindrical roller bearings are distinguished by the arrangement of the lips. Design NU (Figure 1.21b) has two lips on the outer ring, the inner ring being lipless. In design N (Figure 1.21a), the inner ring has two lips, the outer ring has none. Cylindrical roller bearings of designs NU and N are applied as floating bearings because the rollers can freely shift on the lipless ring in the axial direction. Cylindrical roller bearings NJ (Figure 1.20) have two lips on the outer ring and one on the inner ring; they can take up axial forces in one direction. Design NUP (Figure 1.21d) is installed as a locating bearing to sustain frequently reversing axial forces.

As soon as I saw them shipp'd, and gone, I took two Guns upon my Shoulders, and two Pistols at my Girdle, and my great Sword by my Side, without a Scabbard, and with all the Speed I was able to make, I went away to the Hill, where I had discover'd the first Appearance of all; and as soon as I gat thither, which was not less than two Hours (for I could not go apace, being so loaden with Arms as I was) I perceiv'd there had been three Canoes more of Savages on that Place; and looking out farther, I saw they were all at Sea together, making over for the Main.

一见他们上船离开了，我就拿了两支枪背在肩上，两支手枪挂在腰带上，又取了一把没鞘的大刀悬在腰间，尽快向靠海的那座小山上跑去，正是在那儿我第一次发现野人的踪迹。我费了两个多钟头才到达那里，因为我全副武装，负担太重，怎么也走不快。我一上小山就看到，除了我刚才看到的两只独木舟外，还有另外三只在那儿。再往远处看去，只见他们在海面上会合后往大陆方向驶去了。

Now Friday, says I, laying down the discharg'd Pieces, and taking up the Musket, which was yet loaden; follow me, says I, which he did, with a great deal of Courage; upon which I rush'd out of the Wood, and shew'd my self, and Friday close at my Foot; as soon as I perceiv'd they saw me, I shouted as loud as I could, and bad Friday do so too; and running as fast as I could, which by the way, was not very fast, being loaden with Arms as I was, I made directly towards the poor Victim, who was, as I said, lying upon the Beach, or Shore, between the Place where they sat, and the Sea; the two Butchers who were just going to work with him, had left him, at the Suprize of our first Fire, and fled in a terrible Fright, to the Sea Side, and had jump'd into a Canoe, and three more of the rest made the same way; I turn'd to Friday, and bid him step forwards, and fire at them; he understood me immediately, and running about forty Yards, to be near them, he shot at them, and I thought he had kill'd them all; for I see them all fall of a Heap into the Boat; though I saw two of them up again quickly: However, he kill'd two of them, and wounded the third; so that he lay down in the Bottom of the Boat, as if he had been dead.
