Firstly, Receding horizon H〓 control based on state feedback with terminal constraints is proposed for systems with disturbance inputs and parameter perturbations. Linear Fractional Transformation and some existed results on Receding horizon H〓 control for systems without perturbations are introduced.

The results showed that the decomposition of 4-nitroimidazole began with the split of the C—NO2 bond in the temperature range of 185—210℃. The strongly oxidative product NO2 destroyed the instable annulus of 4-nitroimidazole instantly, all the other C＝N, C＝C, C—H and N—H bonds of the five membered ring were broken simultaneously, and the detected gas products of 4-nitroimidazole decomposition were NO2, CO2 and CO.

结果表明，4-硝基咪唑的催化热分解起始于其分子中C-NO2化学键的断裂，温度范围是185~210℃。C-NO2键的强氧化性的裂解产物NO2瞬间作用于4-硝基咪唑分子中不稳定的五员环，使化学键C=N、C=C、C-H和N-H同时被打破。4-硝基咪唑的气体分解产物包括NO2、CO2和CO。

According to the heterogeneous migmatite and granite of South and North Dabie Blocks, and the formula △h=h which was inferred in this paper, the melting of metamorphio rock might make NB uplift about 4. 4km, but SB only about 1. 9km. Therefore, the difference of melting degree of metamorphic rocks of NB and SB led to the volume different, and this could be one of the reasons of different uplift of NB and SB.

根据南、北大别地块混合岩、花岗岩分布不均匀的特点和本文推导的公式Δh=h(〓-1)估算表明，变质岩的熔融可使北大别地块隆升幅度达4.4km，而南大别隆升幅度仅为1.9km，因此，南、北大别变质岩熔融程度差异所引起体积变化的不同，可能是南、北大别地块差异隆升的原因之一。

We suppose that C is a category with involution *, a is a morphism of Category C, h and k are inversive symmetrical morphisms of category C. If there is a morphism x, satisfyingthen x is called a general Moore-Penrose inverse of a on morphism h and k .

Whenp≠0 and q is an n -th primitive root of unity,H has an n~4 -dimensionalquotient algebra H_n isomorphic to DA_n(q~(-1),which is the Drinfeldquantum double of n~2 -dimensional Taft algebra Anq~(-1. This distinguishedproperty draws people's interesting on H .

Methods Peritoneal macrophages of guinea pigs were infected in vitro by three different Leptospira strains, the virulent Leptospira interrogans serovar Lai type strain Lai, the avirulent L. interrogans serovar Lai type strain IPAV, and the nonpathogenic L. biflexa serovar Patoc type strain PatocⅠ, respectively, and heat inactivated Staphylococcus epidermidis was added 0.5, 1.5, 3 and 6 h after infection and incubated for 30 min. The effect of Leptospira on the phagocytosis of macrophage was evaluated by the inactivated Staphylococcus epidermidis phagocytosis rate and phagocytosis index. Phagocytosis and ultrastructure of peritoneal macrophages were observed by transmission electron microscopy 3 h after infection, and changes of cytoskeleton of the macrophages were observed by laser scanning confocal microscopy.

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
