It is important for the application of formal approach and formal specification in all stages of software development to study and design automatic refinement from Z to high-levellanguage: Insure complete formalization in all stages of software development; Avoid antilogy in refinement due to mistaken operation or computative mistake and insure consistency and integrity of system; Due to avoiding manual operation in refinement process, it is feasible to bulid a compile environment that Z specification automatic refine and form high-level programme, this will accelerate the promotion and application of Z in industry.

Z到高级语言自动求精的研究与设计对于形式化方法及形式规格说明应用于软件开发的各个阶段具有非常重要的意义：确保了从需求分析阶段开始的软件开发周期的完全形式化；避免了人工的误操作或演算错误导致的求精前后不一致，保证了系统的一致性和完整性；由于求精过程避免了手工操作，因而Z规格说明自动精化为程序代码的编译环境可以建立，这将会加速Z规格说明在工业界的推广应用。

SHRIMP and LA-ICP-MS zircon U-Pb dating yielded some age data: the Longchahe porphyritic granite is (81.2±1.4)~(83.2±1.4) Ma, the porphyritic granite in Malage-Songshujia area is (82.8±1.7) Ma, the porphyritic granite in Laochang area is (83.3±1.6) Ma and the Baishachong equigranular granite is (77.4±2.5) Ma.

文章首次采用LA-ICP-MS和SHRIMP U-Pb方法对研究区内的花岗岩进行了精确定年，数据表明，不同类型的花岗岩同时或近于同时形成。龙岔河似斑状花岗岩主要形成于(82.0±0.3)~(83.2±1.4)Ma，马拉格－松树脚似斑状花岗岩形成于(82.8±1.7)Ma，老厂似斑状花岗岩形成于(83.3±1.6)Ma，白沙冲等粒花岗岩形成于(77.4±2.5)Ma，均集中形成于晚白垩世。

They can reach 72.04% and 84.5% separately(P.05). 2. The methods such as Percoll uncontinuous density gradient centrifugation, isolation according to the different adhesiveness can be used to isolate and purify rabbit SSC effectively. Spermatogonia mainly distribute between the gradient 27% to 35%(density between 1.0410g/ml to 1.0508g/ml).

Percoll 不连续密度梯度离心和差异粘附等方法可以有效的对兔精原细胞进行分离纯化，其中精原细胞主要分布于密度梯度为27%-35%(密度 1.0410g/ml~1.0508g/ml)的带间，此带中精原细胞的纯度平均达到 60.42%(P.01)。

We cannot tell if a women is urinating or ejaculating outside a medical lab. These fluids all exist trough the urethra so the visible source is the same whitch doesn't help matters.

我们不能让一个女人在实验室里排尿或者射精加上阴精存在于尿道里所以分析他的成分容易被尿液干扰，从而很难得出确切结论。
