1.The results show that the optimum explosive charge for the 37mm fragmentation-blast shell is about 120 gram, a value rather close to those used on shells of similar calibre abroad. This model can be used to conduct scheme demonstration and preliminary design as well as evalution of small bore fragmentation-blast shells.
并以37mm杀伤爆破弹对某型飞机射击的实例进行优化设计计算,结果表明该弹的最佳装药量为120g左右,与国外最新装备的相近口径的杀伤爆破弹的装药量相近,说明本文建立的模型是可行的。
2.Three cases of fragmentation failure were due to upper ureteral stones migrating to the renal pelvis. The success rate of fragmentation on one session was 95.8%(69/72),which was 92.1%(35/38) for upper segment calculi and 100%(34/34) for middle-to-lower segment calculi.
3例失败由于位于输尿管上段的结石移至肾脏,一次碎石成功率95.8%(69/72),其中上段结石成功率92.1%(35/38)、中下段结石成功率100%(34/34)。
3.GP-7 could also induce typical apoptotic morphology changes and DNA fragmentation of K562/ADM and K562 cells, but DNA fragmentation induced by GP-7 in K562/ADM cells was weaker than that in K562 cells.
GP-7可引起K562/ADM和K562细胞典型的凋亡形态学变化和DNA凋亡性降解,但GP-7引起的K562/ADM细胞DNA凋亡性降解弱于K562细胞;
4.RESULTS: ① Detection of internucleosomal DNA fragmentation by DNA ladder assay: After 8-day ELF magnetic field exposure, DNA fragmentation pattern was detected by DNA ladder assay, which was not observed in control groups (free of exposure).
结果:①DNA梯度电泳检测细胞核间DNA裂解情况:SK-HEP-1细胞在极低频磁场处理8d后产生DNA片段条带,对照组中(无磁场处理)则未观察到此特征性DNA条带。
5.This paper verified with grey correlation analysis method that the blastability index of rock is the main fac tor affecting the blasting fragmentation of Huidong Lead-Zinc Mine and also demo nstrated that the adjustment of explosive factor and pattern parameters in blast design is still very important to the control of blasting fragmentation.
本文采用灰色关联分析方法 ,确定出会东铅锌矿影响爆破块度的主要因素为岩石爆破性指数 ,同时指出 ,在爆破设计中 ,调整炸药单耗和孔网参数 ,对控制爆破块度仍有重要作用。

7.DNA fragmentation was visualized by agarose gel electrophoresis. RESULTS: 17-β-Estradiol 0.01-1 μmol · L-1 or estrone 10 - 20 μmol·L-1 elicited typical morphological apoptosis and DNA fragmentation in a concentration-dependent manner in MPM.
结果:17-β-雌二醇0.01-1μmol·L~(-1)和雌酮10-20μmol·L~(-1)均能以剂量依赖方式诱导巨噬细胞产生凋亡的典型形态学改变和特征性DNA片段,staurosporine、放线菌酮和他莫西芬能取消这种作用.
8.It is obvious that in Jialing River basin, many landscape components with good patch cohesion are distributed, forming a pattern of landscape fragmentation.
“温带落叶阔叶林”的斑块间隔小，分布紧密，相似性程度高，聚合性强，但自然连接性较低。
