The results indicated that there were six types of sensilla, namely, finger-like sensilla, platcodeum sensilla, trichoid sensilla, ampullaceous sensilla and chaetic sensilla on the antenna of two wasps. The type, number, and distribution patterns of the antennal sensilla were similar in the two species, but the differences between two sexes were significant.

After two-cluster testing,branch length testing and relative rate testing ,two sequences(Melantitta nigra and Aythya americana) of 15 Cty b sequences were deleted because thek evolutionary rate were heterogeneous. The divergence between Anseriformes and Galliformes was chosen as an anchor point. Nucleotide sequence and amino acid sequence of 13 sequences data set was used to calibrated Anatidae molecular clocks. The results indicated that amino acid sequence is better than nucleotide sequence when divergence time is calculated with two kinds of sequences. The reliable divergence time of Anatidae were estimated with """"1+2TiTv"""" model.

The Antennal ultrastructures of the two closely related wasp species, Aprostocetus prolixus and Aprostocetus fukutai, were observed by scanning electron microscope. The types, numbers, morphological characteristics and distribution patterns of the antennal sensilla of the two species were described, and the differences between two sexes were compared too.

The coordination mode of La can be described as a distorted aquare antiprism, which was completed by two oxygen atoms from one oxalate, four oxygen atoms from four different PDC ligands, and two oxygen atoms from two water molecules.

La呈现四方反棱柱体的配位模式，分别和2个来自同一个草酸配体的氧原子、4个来自4个PDC配体的氧原子以及2个来自2个配位水分子的氧原子配位。

The neighbor-ing two Gd3+ ions are connected by two simple bridged carboxyl groups and a μ2-bridging carboxylgroup. Each G-d3+ ion is simuetaneosly coordinated by two water molecules. So the coordination num-ber of Gd3+ is nine, forming a coordination polyhedron of distorted mono capped square antiprism.

相邻Gd3+离子通过2个简单羧基桥和1个μ2羧基桥联结起来，还有2个水分子配位于每个Gd3+离子，所以Gd3+的配位数为9，形成变形的单帽四方反棱柱体。

Motheds: to select 336 lomars with pulposis or apicitis from the aged and to devide them into two groups. in group the control group,the illed teeth were given only the root canal therapy. in group the experimental group, according to the difference of every root canal, the unobstructed root canals were treated by root canal therapy. while the obstructed ones were given the root canal resinifying, use two kinds of therapy method together to molais' pathological changes.then their curative effects were observed after two year.

Next the discussion in this study, about an ellipse with an angle of attack and two circular cylinders with different diameters in the flow, the aim of this study is investigated for the ability of the present numerical method by solving the suppression of the vortex shedding flow behind the two-cylinder system which was kind of difficult to reach by a Cartesian grid method. In this study, the suppression of the vortex shedding flow is tested to solve a uniform flow past through two different diameter cylindrical in the flow field with Fractional Step Method and Immersed Boundary Method.The numerical method which we investigated is showed that the results of the problem is appropriable in other literatures.

The ISSR markers were fitted to a 3:1 ratio of simplex and duplex segregation for the parental alleles, as the sweet potato was expected to be autohexaploid. Fourteen and nine quantitative trait loci linked to specific ISSR markers were detected for traits in (NH×TN27) and (TN27×NH), respectively. Twenty-two of these QTL-mapped markers were unique to the specific traits, and two were linked to two traits in each linkage map. These markers appear to be applicable to crop improvement.
