For ALIF, this ranged from 0.8 (complete, 100% fusion) to 3.3 (solid fusion of the posterior 25% disc space). For PLIF, the numbers were more aried, ranging from 0.7 (complete, 100% fusion) to 6.9 (solid fusion of posterior 25% disc space with bilateral facetectomy). For intertranserse process fusion, the least motion was with a solid bilateral fusion, with medial healing to the pars (2.0); the greatest motion was found with a solid unilateral fusion without medial healing (6.0). Interspinous process fusion allowed only 1.9 of motion.

前路椎间融合，范围是0.8度（完全、100%融合）到3.3度（后方椎间隙25%的稳定融合）；后路椎间融合范围较大，是0.7度（完全、100%融合）到6.9度（伴有双侧峡部近内侧融合的后方椎间隙25%的稳定融合）；横突间植骨融合，最小值2.0度是双侧偏内侧稳定融合，最大值6.0度是单侧且不偏向内侧融合；椎板棘突间植骨融合只出现1.9度的活动度。

With the inducing time prolonged, the amount of fusion protein increased, and the highest content amounted to 39. 14% of total protein. Different temperature (15℃, 25℃ and 37℃) could induce expression of fusion protein, and the higher inducing temperature was, the more total fusion protein and soluble fusion protein was produced. Most fusion protein was expressed in the cytoplasm and was soluble, a little of fusion protein was expressed in periplasm or expressed as inclusion bodies, and no fusion protein was found in culture. Furthermore, the results of in vitro enzymatic reaction suggested that the fusion protein could catalyze the methylation of theobromine.

随着诱导时间的延长，表达的融合蛋白产量逐渐增加，表达蛋白总量最高可达到菌体总蛋白的39.14％；在15℃、25℃和37℃三个不同的诱导温度下，均能诱导产生融合蛋白，而且产生的融合蛋白的总量及其可溶性部分所占比例均随诱导温度升高而增加；在菌体的各个部位中，融合蛋白主要在细胞质中以可溶的形式进行表达，有少量在外周质中表达或以包含体形式在细胞质中表达。

This article has studied HG70 steel and HS-70 welding wires weldings,the welded joint,welding quality,and the welding operational performance,in restricts under the welding condition,Uses HS-70 welding wires,Experiments the steel plate the weld joint stretch,degree of hardness and the resilience test result indicated that,HG70 steel and HS-70 welding wires weld joints have the low crack sensitivity,The welding quality is good,Its weld joint has the fine mechanics performance,thus explained they had the fine welding match.

0前言非调质钢具有优良的使用性能和较低的生产成本，受到普遍重视。HG70钢是武钢开发的工程结构用钢，具有强度高、低温韧性好的特点。传统高强度钢一般碳当量较高，焊接性能较差。通过加入微量合金元素、采取新的控轧和调质工艺，使得HG70钢在提高强度的同时，亦保持了较高的韧性和较低的碳当量，因而从理论上讲HG70应具有较好的焊接性能，但HG70钢与HS-70焊丝的匹配情况，还有待于分析验证。

The relationships between welding pool width, wire extension and welding parameters including welding current duty ratio, base current, peak current, welding speed and wire-feeding speed were studied.
