Then,we discuss the question that when there is a q-process P,such thatπwhich is theμ-invariant measure orμ-subinvariant measure of a given q-pair,is theμ-invariant measure of P...

第三章分别分了三种情形，对给了保守或π-非保守q-对的μ-不变测度或μ-次不变测度π，何时存在q-过程P，使得π是P的μ-不变测度的问题进行了讨论研究。

Even weassume that such an invariant measure exists,there are still problems related to the nonex-istence of the corresponding functional integral when we apply this technique to concreteproblems,such as constructing gauge invariant operatorsout of gauge variantones.

即使我们假设这样一个不变测度存在，当我们将这一技术应用到具体问题时，比如由规范非不变的算符构造规范不变的算符，仍然存在由于相应的泛函积分不存在而带来的问题。

Many enterprises in advertising language issues often feel confused, in the 'change' and 'unchanged' on the horns of a dilemma,'no change' is very easy for the aging brand;'change' can very easily have unknown risks.

很多企业在广告语问题上常感困惑，在'变'与'不变'的问题上左右为难，'不变'很容易使品牌老化；'变'则很容易产生未知风险。

Hung-fat, director of Shanxi Province Economic and Trade Bureau, the provincial government leadership has repeatedly stressed that the requirements of the province's power plants can no longer take the main source of electricity supply pressure at the local small coal kiln, the quality of the local small coal kiln no guarantee that the supply of instability, although a certain degree of price advantage, but said变就变is not conducive to security and stability of plant production, with the coal industry in our province to implement three major strategies of small coal mines and the implementation of resource integration, requested the power enterprises to adjust the coal supply structure as soon as possible, we must allow for large coal mines to account for more than 50%.

据山西省经委主任洪发科介绍，省政府领导多次强调，要求省内的电厂再不能把电煤供应的主要来源压在地方小窑煤上，地方小窑煤质量没保证、供应不稳定，虽有一定的价格优势，但说变就变，不利于电厂的安全稳定生产，随着我省煤炭行业实施三大战略，对小煤矿实施资源整合，要求电力企业要尽快调整煤炭供应结构，一定要让大矿供的煤能够占到50%以上。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
