Degradation test in vitro was carried out in phosphate buffer solution (0.1M, pH7. 4) at 37 ℃. The buffer solution was changed daily. Degradation test in vivo was implanted the sample to subdermal in adult ICH rat in the scapular area lateral to the dorsal midline. At suitable time the samples were recovered. Molecular weight changes in surface layer and bulk of polymer sample were measured by GPC and weight loss was determined gravimetrically. It was found that the degradation behavior can be regulated by changing the composition of copolymers. The critical compositions from surface to bulk degradation behavior for PGCA, PLCA, PLMCA, PLDCA systems were 15-20, 20-30, 30- 40, 40 of mol percent GA or LA unit in copolymers, respectively. The degradation behavior of PGCA, PLCA, PLMCA, PLDCA systems were compared and analysed. Some factors influencing the degradation character, such as copolymer composition, hydrophobicity, crystallinity and enzyme affect etc. played important role.

In summary, Although in recent years combine development is swift and violent, But because our country vast in territory, The climate and the geography condition as well as the cultivated variety, the planter way have the big difference,Adds on the economical development not to be balanced, Some harvested the machinery jointly the performance and the part key technologies still is not mature,In next period of time, Thresher in our country's grain crops harvest work, Specially in the mountainous area, the knoll patch of land, the interplanting and the miscellaneous grains planted the area was still the essential work machines and tools.

综上所述，尽管近几年联合收割机的发展迅猛，但由于我国地域辽阔，气候和地理条件以及栽培品种、种植方式有较大的差异，加上经济发展不平衡，有些联合收获机械的性能和部分关键技术尚不成熟，在今后一段时间内，脱粒机在我国的粮食作物收获作业中，特别是在山区、丘陵小块地、间作套种和杂粮种植地区仍是不可缺少的作业机具。

ConclusionTo begin with, the blood supply is adequate in the intertransverse area, and the distribution of blood vessels follows some regularities, so to be familiar with the anatomy and to operate carefully can reduce bleeding.

结论横突间及小关节区域血管丰富，走行具有一定规律，熟悉此区域解剖结构并注意操作可减少术中出血；L3、4、L4、5节段行横突间入路腰椎椎体间融合术具有一定可行性。

But pitch is irrelated with length in clauses or utterances; only in tone 3, pitch is negatively correlated with length.

但在小句和语段内部，音高和音长几乎不相关，只有上声位置音高和音长呈负相关。

On the stage of Kongyi Member,the main sedimentary facies are the fluvial fan group and flooding plain,and going with the sedimentary surrounding of minitype limnological fluvial fan—gypsum saline.

研究区的沉积受喜山运动影响，在盆地南区产生拉张裂陷，形成孤立的沉积小盆地，并在这种沉积环境中沉积了孔店组地层，孔一段时期以盆缘冲积扇群、洪泛平原为主，局部伴有小型准盐化湖沼的冲积扇—膏盐湖沉积环境。

Positioning is examined by using micrococcal nuclease to examine cleavage sites relative to a restriction site at the 5 end of the gene.

最初基因会展现一个核小体的模型，它是由穿过基因一段有效距离的启动子构成的；在3ˊ端范围中定位作用遗失。

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.
