角

They are characterize by irregular and subangular with sandy filling or no filling,and some of them are jointable.

经研究，金顶矿区存在两种成因的角砾岩：构造-膏溶角砾岩和底辟-侵位角砾岩。

The amount of attached gingiva is increased through eversion of the sulcular epithelium, appearing first as immature non keratinized tissue (known as "red patch") and then as keratinized tissue Fig.

数额重视牙龈是通过增加外翻的沟上皮细胞，出现第一次作为不成熟的非角化组织，然后作为角化组织（图4）；的过程中角化需要28至42天[ 15 ] 。

Seven patients were admitted into this department in acute phase of trauma, repair of popliteal artery in 2 patients and repair of PMC and MCL in 4 patients were performed in this phase. Arthroscopic combined reconstruction of ACL and PCL with autografts was performed in all patients from 4 to 12 weeks after trauma, reconstruction of PLC with the posterior half of biceps femoris tendon tenodesis in 3 patients and reconstruction of PMC and MCL with femoral fascia in 1 patient were completed simultaneously.

方法］自2001年9月~2005年2月，13例病人（13膝）经关节镜检查证明ACL和PCL均断裂，其中5膝伴后内侧角、内侧副韧带损伤，4膝伴后外侧角损伤，2膝伴外侧半月板破裂，1膝伴内侧半月板损伤，3膝伴动脉损伤，2膝伴腓分神经损伤。7例病人于损伤后急性期入院，2膝于急性期行血管探查修复，4膝行膝后内侧角、内侧副韧带修复。13例病人于伤后4~12周在关节镜下行自体移植物单束ACL和PCL联合重建术，其中4例同期后1/2 股二头肌腱重建后PLC，1例同期阔筋膜PMC、MCL重建。

Some spore-pollen assemblages of late Trias and the youngest zircon of 225Ma were also obtained in this type.Deriveration of the ore is from the upper crust according to the features of trace elements,zircorn U-Pb age and initial value of ~(87)Sr/~(86)Sr.It has not any charateristics of the mantle.

底辟-侵位角砾岩是本次工作新发现的，它在空间上与构造-膏溶角砾岩密切伴生，剖面上呈脉状或火焰状分布，局部呈脉状穿刺于围岩中，其胶结物中含有晚三叠世的孢粉组合，最年青锆石的年龄为225Ma，角砾岩本身是铅和锌的富矿体。

Keratinase can degrade disulfide bonds in the keratin obviously,and make it hydrolysable,which can effectively solve the problem of serious pollution in the traditional unhairing process in leather-making industry.

角蛋白酶可以特异降解维系角蛋白结构的双硫键，使角蛋白发生水解，从而达到使动物皮脱毛的目的，因而能够从根本上消除传统制革工业硫化碱脱毛产生的严重污染。

The separation angle about beam and beam is depended on the vice structure angle:the design of splitting Li P prism is better about the need of beam vertical out;the design of splitting Grand · Thompson prism is better about the need of big splitting angle .

出射的 光与光的分离角与副结构角有关；对于光垂直出射的需要，选用分束李普奇棱镜设计为好；对于大分束角的需要，选用分束格兰·汤普逊棱镜设计为好。

For improving the survivability of the guided weapons in target district,aggrandizing its damaging power to target,and to satisfy the demand of the actual military tactics,the guided weapon must attack targets in the desired impact angle,thus the problem of homing guidance with impact angle constraints is put forward.

为提高制导武器在目标区域的生存能力，增大对目标的杀伤威力，以及实际战术应用的需要，需要武器按期望的方位角、俯冲角对目标实施攻击，因此提出了带有碰撞角约束的导引问题。
