The predicted amino acid sequence of the gene show a rather high homology(84.47% amino acid identities)with Haemaphysalis longicornis(H.longicornis) TnI (GenBank,GI:14041807).Furthermore, the actin-binding domains of troponin I in predicted amino acid sequence, just the same as H. longicornis ,at the amino acid residues 147-167, suggesting the gene is K haemaphysaloides TnI gene.

经同源性比较，该基因预测的氨基酸序列与长角血蜱肌钙蛋白Ⅰ(GenBank，GI：14041807)有很高的同源性(同源性为84.47%)，肌动蛋白结合位点位于147-167氨基酸处，且与长角血蜱肌钙蛋白Ⅰ肌动蛋白结合位点完全相同，表明该基因是镰形扇头蜱肌钙蛋白Ⅰ基因。

Results The micronuclear rate in medium dosage group and high dosage group were significantly higher than that of control group(P＜0.01). The ratio of sperm malformation in middle group and high group were higher than those of controls (P＜0.01).The ratio of sperm malformation increased in dose-dependent manner with dose, a dose-response relationship was found. Conclusion The DBP contamination presents the positive results under the certain dosage to the mouse marrow micronucleus experiment and the spermatozoon abnormal experiment.

结果 中、高剂量组微核率与阴性对照组相比明显升高(P＜0.05)，且各剂量组微核率随染毒浓度的增加而升高，呈现剂量-反应关系(r=0.937，P＜0.01)；中、高剂量组精子畸形率与阴性对照组比较差异有统计学意义(P＜0.05)，且各剂量组精子畸形率随染毒浓度的增加而升高，呈剂量-反应关系(r=0.904，P＜0.01)，畸形精子中以无钩为最多，其次是香蕉形、尾折叠、双头，分别为4.5%、3.09%和1.32%，结论 DBP染毒在一定剂量下对小鼠骨髓微核试验和精子畸形试验呈现阳性结果。

The microkemel and sperm cell abnomalities were analyzed. Results The micronuclear rate in medium dosage group and high dosage group were significantly higher than that of control group(P＜0.01). The ratio of sperm malformation in middle group and high group were higher than those of controls (P＜0.01).The ratio of sperm malformation increased in dose-dependent manner with dose, a dose-response relationship was found.

When manufacture part which with curved surface by of contour machining,the shape of profile modeling is not as same as the part,they also without simple relation of minify or magnify.

仿形车、铣加工曲面零件，主要是通过靠模曲线来实现的，靠模曲线形状通过带有滚轮的靠模触头传递到刀具上，加工出零件所需的曲面形状。靠模曲线与零件曲面有什么样的关系？

Pomfret are Perciform, pomfret Branch, body short and high, very-side flat, slightly diamond-shaped head and small, round kissing, mouth small, thin teeth.

鲳鱼属于鲈形目，鲳科，体短而高，极侧扁，略呈菱形，头较小，吻圆，口小，牙细。

The use of the ratio between the migration length and the diameter of the comet head (LDR, see Tice et al., 2000) as a parameter to represent the data of the genotoxic effects in D. polymorpha was found (Bolognesi et al., 2004) to be able to reduce the inter-individual variability of the data (from 20–30% for TL to 5–10% for LDR).

使用的，两者的比例约为迁移长度和直径的彗星头（低剂量辐射，见泰斯对持不同等人， 2000年）作为参数，以代表该数据的遗传毒性效应四多形被发现（ bolognesi等人， 2004年）为了能够减少跨个别变异性数据（从20-30 ％铊，以5-10 ％的LDR ）。
