The yeast Pxa1p and Pxa2p dimerize to form a functional transporter involved in very long chain fatty acid oxidation in the peroxisome. The formation of PMP70 assembles as dimeric or oligomeric forms on peroxisomal membranes implies that Pxa2p may form a homodimers.

同源於Pxa2p的PMP70被证实会形成同源二聚体或多聚体，这对於Pxa2p是否也会形成同源二聚体或多聚体的研究，是非常有意义的。

Applying the concept of star dual, which is introduced by Moszynska, we establish some inequalities for star duals of intersection bodies. Hence, we present a new kind of duality between intersection bodies and projection bodies.

采用Moszynska引入的星对偶的概念，我们在第五章中研究相交体的星对偶体，从而更进一步地揭示了投影体和相交体两者之间的对偶关系；引入了对偶混合体的概念。

A method of forming a glass melt including heating a glass feed material in a first melting furnace to form a glass melt, flowing the glass melt into a second melting furnace through a refractory metal connecting tube, and further heating the glass melt in the second melting furnace.

研究结果表明，二沉池出水中的颗粒主要为小絮体，SS超标主要是因为污泥中小絮体比例过大，降低污泥中的小絮体比例便可以降低出水SS，但因氧化沟工艺的污泥龄一般较长，所以污泥老化现象严重，小絮体的比例一般较高。

The study we have performed demonstrated that the main roof first broke with asymmetry character; gully mining-induced slope was divided into multilateral blocks by surface advance cracks. Furthermore, multilateral blocks rotated and subsided by the function of extrusion and friction between the broken rock block above the goaf and the rock mass advance the coalface.

冲沟坡体下开采时，基本顶初次破断具有不对称性；冲沟采动坡体被地表超前裂隙切割成多边块状，并在两侧坡体的夹持摩擦作用下缓慢回转下沉；相同地质条件下，坡角越大，采动坡体对工作面矿压影响越大。

Vegetative agriculture is a kind of productive system, which concentrates mainly on the production of vegetative organs such as stems and leaves of plants including herbages, green fodder, vegetations, flowers, teas, tobaccos, as well as rhizome and fibre crops. The principal difference between the traditional agriculture and vegetative agriculture is that the former focuses on the productivity of the seed in the whole growing period and the latter focuses on the productivity of available nutrients at the different growing stages of plants.
