進一步對xynba進行了脫糖基化處理得到xynbb ，其分子量恢復到23kd ，證明xynba是糖基化蛋白。通過對畢赤酵母重組表達的木聚糖酶xynba 、脫糖基化的木聚糖酶xynbb以及橄欖綠鏈黴菌a1所產原酶xynb之間酶學性質的比較發現：三種酶的最適ph差異不大， xynb和xynba均為5 . 2 ， xynbb為5 . 0 ； xynb和xynba的最適溫度均為60 ， xynbb降為50 ：在耐熱性上， xynba由於糖基化作用熱穩定性明顯高於未糖基化的xynb和xynbb ； xynba和xynbb的比活性分別為883 . 88iu mg和832 . 51iu mg ，明顯低於原酶的比活2814 . 45iu mg ； xynb和xynba的km值相當，分別為21 . 56 （ g kg ）和20 . 87 （ g kg ） ，而xynbb的km值較大為27 . 10 （ g kg ） ； xynba和xynbb的vmax相差不大，分別為4568 mol mg ? min和5329 mol mg ? min ，明顯低於xynb的27623 mol mg ? min此外三種酶均無纖維素酶活性，對胃蛋白酶和胰蛋白酶有很好的抗性，且對作用環境中的各種離子、表面活性劑、螯合劑不敏感。通過對不同木聚糖的酶解產物的糖份分析發現：以樺木木聚糖為底物時，酶解產物主要為木三糖和木四糖，含量分別為68 . 43和16 . 50 ，另外還含有11 . 79的木二糖；以玉米芯木聚糖為底物時，酶解產物主要為木二糖和木三糖，含量分別為81 . 78和11 . 55 。The shutdown is a potential threat to heating systems in harbin, one of china ' s coldest cities, where day temperatures are already below freezing as winter approaches

由於加熱只發生在白天，因此50公里高度上的溫度日變化約為4k 。During winter nights and under clear skies, the ground surface is cooled rapidly by radiating heat off to space. the air temperature near the ground will also fall and when the grass temperature drops below zero degrees celsius, hoar frost will form by direct sublimation of water vapour onto the grass surface
在冬天的晚上，如果天氣晴朗，地面的熱量會透過輻射快速散失，貼近地面的空氣也同時降溫，當草面溫度降到攝氏零度以下時，空氣里的水蒸氣便會在草面凝華成為白茫茫的霜。Thermistors - directly heated positive step - function temperature coefficient - blank detail specification - inrush current application - assessment level ez
