After analyzing glutinous rice waxy gene sequence reported by previous studies, two pairs of dominant and codominant STS molecular markers based PCR were designed for distinguishing glutinous rice, according to the distinctions between glutinous rice wx gene and nonglutinous rice Wx gene. Moreover, the whole sequences of the two Wx genes of nonglutinous rice reported by others were also aligned, and another two pairs of dominant STS molecular markers were designed to discriminate Wxa from Wxb based on the special site between the two genotypes. Then, corresponding rice genotypes were identified by the established new markers.

On the base of the single-diameter laser-scanned measuring technology, a double direction laser-scanned measuring system is presented. Which combinate the laser-scanned measuring technology with special optical system. In the system, the collimation semiconductor laser-scanned beam scanning two perpendiculars direct of one plane of the measured workpiece at the same time is made. The beams with the dimension information of two perpendiculars direct are processed by the scanning receive system, the high-speed photoelectric transition and electronic data process. Two measured results of the diametric directs and ellipse tolerance,etc, parameter, of the turning workpiece on the same plane are obtained by non-contact automatic measurement. The problem of non-contact measurement of two perpendiculars direct of one plane of turning workpiece is settled. It processes many peculiarities, such as high speed, high accuracy and non-contact automatic measurement, etc.

It was seen that strain 6055 generated three kinds of dextransucrases whose molecular weights were 151 kDa,142kDa and 117kDa,respectively.Among them,the former two ones were found both in supematants and cell wall,while the later was only found in the fermentation liquor.Strain DM 1-2 synthesized two kinds of dextransucrases,and their molecular weights were 183kDa and 142kDa,respectively.The former existed both in cell wall and out of cell,but the later only was located on cell surface.Strain PC 13 produced three kinds of dextransucrases,and their molecular weights were 148kDa, 138kDa and 115kDa,respectively.The former two ones were ectoenzyme while the later was linked to cell.Resembled to strain 6055,strain L4 produced two types of dextransucrases coexisting in supernatants and cell wall with molecular weights of 145 kDa and 136kDa,respectively,but the dextransucrase of 115kDa was only found in free-cells supernatants.

其基本原理是建立在球面天文学和初等几何中的轨迹作图法基础上的，观测一个天体的天顶距，则航船就位于以星下点为圆心，此星天顶距为半径的船位圆上，观测两个天体或者不同时间同一天体的两个观测值，就可以得到两个船位圆，则航船一定在两个船位圆的一个交点上。

Firstly, according to electromagnetic field theory, the 2-dimensional (2-D) mathematical model of a three phase squirrel-cage Y802-2 induction motor is developed. Then general equations can be deduced from finite element discrete and functional analysis. The motor's 2D solving region of electromagnetic field is given based on the boundary conditions and assumption conditions of the squirrel-cage induction motor. Through finite element mothod and inner–outer convergence method, magnetic field distributions and magnetic forces of bars can be calculated in following rotor conditions: health rotor, one single broken bar, two adjacent broken bars, two broken bars with one good interval, two broken bars with two good interval and four adjacent broken bars.

I got on Board the Ship, as before, and prepar'd a second Raft, and having had Experience of the first, I neither made this so unwieldy, nor loaded it so hard, but yet I brought away several Things very useful to me; as first, in the Carpenter's Stores I found two or three Bags full of Nails and Spikes, a great Skrew-Jack, a Dozen or two of Hatchets, and above all, that most useful Thing call'd a Grindstone; all these I secur'd together, with several Things belonging to the Gunner, particularly two or three Iron Crows, and two Barrels of Musquet Bullets, seven Musquets, and another fowling Piece, with some small Quantity of Powder more; a large Bag full of small Shot, and a great Roll of Sheet Lead: But this last was so heavy, I could not hoise it up to get it over the Ship's Side.

我像前次那样上了船，并又做了一个木排。有了上次的经验，我不再把木排做得像第一个那么笨重了，也不再装那么多货物了，但还是运回了许多有用的东西。首先，我在木匠舱房里找到了三袋钉子和螺丝钉，一把大钳子，二十来把小斧，尤其有用的是一个磨刀砂轮。我把这些东西都安放在一起，再拿了一些炮手用的物品，特别是两三只起货用的铁钩，两桶枪弹，七支短枪、一支鸟枪，还有一小堆火药，一大袋小子弹，还有一大卷铅皮。可铅皮太重，我无法把它从船上吊到木排上。

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。
