Extensive recent research efforts have established that constant-round concurrent/resettable zero-knowledge for non-trivial languages cannot be achieved in the plain model without setup assumptions.

大量和深入的最新研究已经证明对于非平凡的语言常数轮的并发及可重置的零知识系统在没有Setup假设的朴素模型下是不存在的。

Some statistics reports show that in 80％(566/670) of environmental protection criminal responsibility legal cases were about waste in 2006, and the illegal abandon of the construction waste was 60％ of the violative Waste Disposal Act cases , which was showed in the 2007 court verdicts of Taichung District Prosecutors Office. According to the examples, which were studied in this study, those nouns, reuse, resource recycling, and regeneration were defined and evidence the important of the control structure.

经研究结果显示，95年「台湾各地方法院检察署环保刑事侦查案件终结统计」，废弃物件数共566件，占全部670件数之8成以上，另96年台湾台中地方法院裁判书-刑事类之查询结果，其中营建废弃物之任意弃置约占违反废弃物清理法案件之6成，辅以本研究中所列举各案例，可确实得知如何厘清及汇整废弃物、再利用、再生资源、回收再利用、再生利用、再生产品及应回收废弃物等名词定义及管制架构之重要性，因此，如何建构「废弃物是错置资源」观念，进而消弭环境污染事件及后续衍生之清理管制问题，以提升生活环境品质，已是实现零废弃目标及刻不容缓之国际趋势。

System.out.println("a.length="+ a.length); System.out.println("b.length ="+ b.length);// The handles inside the array are // automatically initialized to null: for(int i = 0; i nbsp;b.length; i++) System.out.println; System.out.println("c.length ="+ c.length); System.out.println("d.length ="+ d.length); a = d; System.out.println("a.length ="+ a.length);// Java 1.1 initialization syntax: a = new Weeble { new Weeble, new Weeble }; System.out.println("a.length ="+ a.length);// Arrays of primitives: int e;// Null handle int f = new int[5]; int g = new int[4]; for(int i = 0; i nbsp;g.length; i++) g = i*i; int h ={ 11, 47, 93 };// Compile error: variable e not initialized://!

句柄。此时，编译器会禁止我们对这个句柄作任何实际操作，除非已正确地初始化了它。数组b被初始化成指向由Weeble句柄构成的一个数组，但那个数组里实际并未放置任何Weeble对象。然而，我们仍然可以查询那个数组的大小，因为b指向的是一个合法对象。这也为我们带来了一个难题：不可知道那个数组里实际包含了多少个元素，因为length只告诉我们可将多少元素置入那个数组。换言之，我们只知道数组对象的大小或容量，不知其实际容纳了多少个元素。尽管如此，由于数组对象在创建之初会自动初始化成null，所以可检查它是否为null，判断一个特定的数组&空位&是否容纳一个对象。类似地，由基本数据类型构成的数组会自动初始化成零、null或者false。
